a) The purchase price of the new equipment is $20,531.76.
b) The amount of interest that will have to be paid is $6,948.24.
The purchase price of the new equipment for New Bread Bakery can be found using the formula for the present value of an annuity:
PV = PMT * [(1 - (1 + i)^(-n)) / i]
Where PV is the present value (or purchase price), PMT is the monthly payment, i is the monthly interest rate, and n is the number of payments.
Plugging in the given values:
PV = 458 * [(1 - (1 + 0.092/12)^(-5*12)) / (0.092/12)]
PV = 458 * [(1 - (1 + 0.00767)^(-60)) / 0.00767]
PV = 458 * [(1 - 0.6887) / 0.00767]
PV = 458 * 40.4624
PV = 18,531.76
The purchase price of the new equipment is $18,531.76. However, this does not include the down payment of $2000. So, the total purchase price is:
PV + Down Payment = 18,531.76 + 2000 = $20,531.76
To find the amount of interest that will have to be paid, we can subtract the purchase price from the total amount paid over the five years:
Interest = (458 * 5 * 12) - 20,531.76 = 27,480 - 20,531.76 = $6,948.24
Therefore, the amount of interest that will have to be paid is $6,948.24.
(a) The purchase price of the new equipment is $20,531.76. (b) The amount of interest that will have to be paid is $6,948.24.

Based on the following figure, determine which value below is correct.
The correct measure is given as follows:
x = 6.
What are vertical angles?Vertical angles are angles that are opposite by the same vertex on crossing segments, hence they share a common vertex, thus being congruent, meaning that they end up having the same angle measure.
Over vertex C, the two angles are congruent, hence the value of x is obtained as follows:
12x - 9 = 6x + 27
6x = 36
x = 6.
(as the vertical angles are congruent, we can just equal the measures of the two angles and then solve the expression for the value of x).

I need help with number 1 the tan= 4/3, lies in quadrant ||| Find sin20
It’s due tonight at 11:59 and I’m struggling
Step-by-step explanation:
Step 1: Simplify the identity we need to find
[tex] \sin(2x) = 2 \sin(x) \cos(x) [/tex]
So we need to find sin and cos
Here, we are given tan(x)
A simple way to find sin (x) and cos(x) when given tan(x) is to use the definition of the trig functions of acute angles.
[tex] \tan( \alpha ) = \frac{y}{x} [/tex]
[tex] \cos( \alpha ) = \frac{x}{r} [/tex]
[tex] \sin( \alpha ) = \frac{y}{r} [/tex]
where r is
[tex]r = \sqrt{ {x}^{2} + {y}^{2} } [/tex]
Here, y is 4 and x is 3.
So
[tex]r = \sqrt{ {3}^{2} + {4}^{2} } = 5[/tex]
Since both cosine and sine are in quadrant 3, they are both negative.
Know we can plug in the knowns, since we know x,y, and r.
[tex] \cos( \alpha ) = - \frac{3}{5} [/tex]
[tex] \sin( \alpha ) = - \frac{4}{5} [/tex]
Now plug in the knowns for sin 2a
[tex] \sin(2 \alpha ) = 2( - \frac{3}{5} )( - \frac{4}{5} ) = \frac{24}{25} [/tex]

Use the properties of logarithms to expand the expression as a sum, difference, and/or constant multiple of logarithms. (Assume all variables are positive.)
The expanded form of the expression as a sum constant multiple of logarithms is:
log₄(xy⁵z⁴) = log₄(x) + 5log₄(y) + 4log₄(z)
What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
According to the problem, we will use some of the basic logarithmic properties,
Given expression,
log₄(xy⁵z⁴)
We can use the properties of logarithms to expand the expression:
log₄(xy⁵z⁴) = log₄(x) + log₄(y⁵) + log₄(z⁴)
Using the properties of logarithms, we can separate the terms inside the logarithm as separate logarithms, where the multiplication of variables is represented as a sum of logarithms.
So, we have:
log₄(xy⁵z⁴) = log₄(x) + 5log₄(y) + 4log₄(z)
Therefore, the expanded form of the expression as a sum constant multiple of logarithms is:
log₄(xy⁵z⁴) = log₄(x) + 5log₄(y) + 4log₄(z)

Step-by-step explanation:
The scatter plot shows a collection of points on a coordinate plane. To determine which of the given graphs shows a line that fits the data, we need to analyze the points and their distribution.
From the given points, we can observe that there is no clear linear relationship between the x and y variables. However, we can see that there is a cluster of points between (4,2) and (7,8), and the rest of the points are scattered around this cluster. Therefore, any line that fits the data should pass through this cluster of points.
Now, let's analyze each option:
The first option shows a line passing through (6,6) and (7,7). While these two points are part of the cluster, the line does not seem to fit the rest of the data very well.
The second option shows a line passing through (4,5) and (5,6). These points are also part of the cluster, and the line seems to fit the data reasonably well.
The third option shows a line passing through (3,3) and (4,4). These points are near the edge of the cluster, but the line seems to fit the data reasonably well.
The fourth option shows a line passing through (1,2) and (7,8). While these two points are part of the cluster, the line does not seem to fit the rest of the data very well.
Based on the analysis above, the second and third options seem to be the best fits for the data. However, the second option seems to be a slightly better fit than the third option since the line passes through two points that are closer to the center of the cluster. Therefore, the answer is:
scatter plot with points plotted at 1 comma 2, 1 comma 3, 3 comma 2, 3 comma 3, 4 comma 2, 4 comma 5, 5 comma 6, 6 comma 6, 7 comma 8, 8 comma 7, 9 comma 10, and 10 comma 9, with a line drawn through the points 4 comma 5 and 5 comma 6.

What is the end behavior of y as x goes to negative infinity in
the equation y = -3x^5 + 4x^2 – 7?
The end behavior of y as x goes to negative infinity in the equation y = -3x^5 + 4x^2 – 7 can be determined by looking at the leading term of the polynomial, which is -3x^5. As x goes to negative infinity, this term will dominate the other terms and determine the end behavior of the function.
Since the degree of the leading term is 5, which is an odd number, and the coefficient is negative, the end behavior of the function will be that y goes to positive infinity as x goes to negative infinity. This can be written in notation as:
lim(x→-∞) y = +∞
In conclusion, the end behavior of y as x goes to negative infinity in the equation y = -3x^5 + 4x^2 – 7 is that y goes to positive infinity.

For what values(s) of x does h(x)=−10?
x= ___
The value of h(-9)= 26 using the function h(x)=−2x+8
And, the value of x for which h(x) = -10 is x = 9.
To evaluate h(-9), we simply plug in -9 for x in the function h(x) = -2x + 8:
h(-9) = -2(-9) + 8
h(-9) = 18 + 8
h(-9) = 26
So the value of h(-9) is 26.
To find the value(s) of x for which h(x) = -10, we can set the function equal to -10 and solve for x:
-2x + 8 = -10
-2x = -18
x = 9

The pressure of a gas varies jointly as the amount of the gas (measured in moles) and the temperature and inversely as the volume of the gas. If the pressure is 1170 kpa (kiloPascals) when the number of moles is 6, the temperature is 260 kelvin�, and the volume is�720 cc, find the pressure when the number of moles is 3, the temperature is�280 k, and the volume is 180 cc
The formula for the pressure of a gas is given by the Ideal Gas Law, which states that P = nRT/V, where P is the pressure, n is the amount of gas in moles, R is the ideal gas constant, T is the temperature in kelvin, and V is the volume in cubic centimeters (cc).
Given the initial conditions, we can find the value of the ideal gas constant R:
1170 kpa = (6 moles)(R)(260 K) / (720 cc)
R = (1170 kpa)(720 cc) / (6 moles)(260 K)
R = 8.27 kpa·cc/mol·K
Now, we can use this value of R to find the pressure under the new conditions:
P = (3 moles)(8.27 kpa·cc/mol·K)(280 K) / (180 cc)
P = 3898.6 kpa·cc / 180 cc
P = 2166 kpa
Therefore, the pressure of the gas when the number of moles is 3, the temperature is 280 K, and the volume is 180 cc is 2166 kpa.

Explain how to use equivalent fractions to compare the fractions 3/4 7/12
To compare fractions using equivalent fractions, we need to find a common denominator, convert each fraction to an equivalent fraction with that denominator, and then compare the numerators directly.
To compare fractions 3/4 and 7/12 using equivalent fractions, we need to find a common denominator for both fractions. A common denominator is a number that is divisible by all the denominators of the fractions being compared. In this case, the least common denominator (LCD) for 4 and 12 is 12.
To convert 3/4 to an equivalent fraction with a denominator of 12, we need to multiply both the numerator and denominator by 3. This gives us the equivalent fraction of 9/12.
To convert 7/12 to an equivalent fraction with a denominator of 12, we need to multiply both the numerator and denominator by 1. This gives us the equivalent fraction of 7/12.
Now that both fractions have the same denominator, we can compare them directly. We can see that 9/12 is greater than 7/12 since 9 is greater than 7. Therefore, 3/4 is greater than 7/12.
This method allows us to compare fractions with different denominators and make accurate comparisons based on the relative size of the numerators.

A rectangular swimming pool in a small recreation centre can hold 60 000 L of water. A new, larger recreation centre is being built with a pool that is a scaled-up (enlarged) version of the smaller centre's pool. If the new pool can hold 3 039 180 L of water, what was the scale factor from the original pool's dimensions (length, width, and height) to the new pool's dimensions?
The scale factor from the original pool's dimensions to the new pool's dimensions is approximately 3.682.
The volume of a rectangular prism (such as a swimming pool) is given by the formula V = lwh, where l is the length, w is the width, and h is the height.
Let x be the scale factor from the original pool's dimensions to the new pool's dimensions. Then, the dimensions of the new pool can be expressed as lx, wx, and hx, where l, w, and h are the dimensions of the original pool.
We know that the original pool can hold 60,000 L of water, so we can set up the equation:
60,000 = lwh
Substituting in lx for l, wx for w, and hx for h, we get:
60,000 =[tex](lx)(wx)(hx)[/tex]
We also know that the new pool can hold 3,039,180 L of water, so we can set up another equation:
3,039,180 = [tex](lx)(wx)(hx)[/tex]
The result of dividing the second equation by the first equation is:
3,039,180/60,000 = [tex](lx)(wx)(hx)/(lx)(wx)(hx)[/tex]
Simplifying, we get:
50.653 =[tex]x^3[/tex]
The result of taking the cube root of both sides is:
x ≈ 3.682
Therefore, the scale factor from the original pool's dimensions to the new pool's dimensions is approximately 3.682.

Work out the cincumference of a cylinder with a 6 cm radius and a 4 cm height
In the following question, among the conditions given, the circumference of a cylinder is "20π cm, or approximately 62.83 cm" with a 6 cm radius and a 4 cm height.
The formula for the circumference of a cylinder is:
Circumference = 2πr + 2πh
where r is the radius of the circular base and h is the height of the cylinder.
In this case, the radius is 6 cm and the height is 4 cm, so we can plug those values into the formula:
Circumference = 2π(6) + 2π(4)
Circumference = 12π + 8π
Circumference = 20π

The domain of a logarithmic function is the set of all values for which the function is defined. In the case of y = log(5x+6), the function is only defined for values of x that make the expression inside the logarithm, 5x+6, greater than zero. This is because the logarithm of a negative number or zero is not defined.
To find the domain analytically, we need to solve the inequality 5x+6 > 0 for x:
5x+6 > 0
5x > -6
x > -6/5
This means that the domain of the function is all values of x greater than -6/5. In interval notation, this can be written as (-6/5, infinity).
So the domain of the logarithmic function y = log(5x+6) is (-6/5, infinity).

Find the domain of each function and each composite function. (Enter your answers using interval notation.)
domain of f
domain of g
domain of f ∘ g
domain of g ∘ f
The domains of each function and each composite function are as follows:
domain of f: (-∞, ∞)
domain of g: (-∞, ∞)
domain of f ∘ g: (-∞, ∞)
domain of g ∘ f: (-∞, ∞)
To find the composite functions f ∘ g and g ∘ f, we need to substitute the function g(x) into f(x) for f ∘ g, and the function f(x) into g(x) for g ∘ f.
(a) f ∘ g = f(g(x)) = f(x3 + 1) = 3(x3 + 1) − 8 = 3x3 + 3 − 8 = 3x3 − 5
(b) g ∘ f = g(f(x)) = g(3x − 8) = (3x − 8)3 + 1 = 27x3 − 72x2 + 64x − 511
The domain of a function is the set of all values of x for which the function is defined.
The domain of f is all real numbers, since there are no restrictions on the values of x. So the domain of f is (-∞, ∞).
The domain of g is also all real numbers, since there are no restrictions on the values of x. So the domain of g is (-∞, ∞).
The domain of f ∘ g is the same as the domain of g, since the values of x are first substituted into g(x) before being substituted into f(x). So the domain of f ∘ g is (-∞, ∞).
The domain of g ∘ f is the same as the domain of f, since the values of x are first substituted into f(x) before being substituted into g(x). So the domain of g ∘ f is (-∞, ∞).
Therefore, the domains of each function and each composite function are as follows:
domain of f: (-∞, ∞)
domain of g: (-∞, ∞)
domain of f ∘ g: (-∞, ∞)
domain of g ∘ f: (-∞, ∞)

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Find the factors of function f, and use them to complete this statement. f ( x ) = 2 x 4 − x 3 − 18 x 2 + 9 x From left to right, function f has zeros at x = , x = , x = , and x = .
From left to right, function f has zeros at x = 0, x = 3, x = -3, x = 1/2, and x = -3/2.
What, in your perspective, does a function accomplish?An expression, rule, or law in mathematics that explains how one independent variable and one dependent variable are connected (the dependent variable).
The factors of the function f(x) can be found by factoring the expression:
f(x) = 2x⁴ - x³ - 18x² + 9x = x(2x³ - x² - 18x + 9)
To find the zeros of f(x), we need to find the values of x that make the expression in the parentheses equal to zero:
2x³ - x² - 18x + 9 = 0
We can use synthetic division or other methods to factor this polynomial and find its zeros. Alternatively, we can use the Rational Zeros Theorem to test possible rational zeros:
Possible rational zeros: ±1, ±3, ±9, ±1/2, ±3/2, ±9/2
Testing x = 1: 2(1)³ - (1)² - 18(1) + 9 = -8, not a zero
Testing x = -1: 2(-1)³ - (-1)² - 18(-1) + 9 = 28, not a zero
Testing x = 3: 2(3)³ - (3)² - 18(3) + 9 = 0, a zero
Testing x = -3: 2(-3)³ - (-3)² - 18(-3) + 9 = 0, a zero
Using polynomial division or factoring by grouping, we can factor the polynomial further:
2x³ - x² - 18x + 9 = (x - 3)(2x² + 5x - 3)
The quadratic factor can be factored using the quadratic formula or other methods:
2x² + 5x - 3 = (2x - 1)(x + 3)
Therefore, the zeros of f(x) are:
x = 0 (from the factor x)
x = 3 (from the factor x - 3)
x = -3 (from the factor x + 3)
x = 1/2 (from the factor 2x - 1)
x = -3/2 (from the factor 2x - 1)
So the completed statement is:
From left to right, function f has zeros at x = 0, x = 3, x = -3, x = 1/2, and x = -3/2.

been trying to figure this one out for hours, please help
The solution of the system of equations is ([2+9.48i]/2, 17+9.48i).
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
The given system of equations are y=(x-2)²+35 ----(i) and y=-2x+15 ----(ii).
Here, equation (i) = (ii)
(x-2)²+35= -2x+15
x²-4x+4+35= -2x+15
x²-4x+39= -2x+15
x²-4x+39+2x-15=0
x²-2x+24=0
x²-2x+24=0
By using quadratic formula, we get
x = [-b ± √(b² - 4ac)]/2a
x=[2±√((-2)² - 4×1×24)]/2×1
x=[2±√(-90)]/2
x=[2±9.48i]/2
Here, x=[2+9.48i]/2 and x=[2-9.48i]/2
So, y=2+9.48i+15=17+9.48i
Therefore, the solution of the system of equations is ([2+9.48i]/2, 17+9.48i).
