Option (c) has the same equation as above after simplification, so the answer is (c):y-8=-0.2(x+10).

Simplification involves reducing an expression, equation, or problem to a simpler form. This can involve performing operations such as combining like terms, factoring, or canceling out common factors.

Point-slope form is a way of writing the equation of a straight line in two-dimensional space, using a given point on the line and the line's slope.

The point-slope form equation for a line passing through a point (x1, y1) with slope m is:y - y1 = m(x - x1).

In the given question,

To write the equation of a line in point-slope form, we need to use the formula:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is any point on the line.

We are given two points on the line: (-10, 8) and (10, 4). We can use these points to find the slope of the line:

m = (y2 - y1) / (x2 - x1)

= (4 - 8) / (10 - (-10))

= -0.15

Now we can use the point-slope form with the point (-10, 8) and slope -0.15:

y - 8 = -0.15(x - (-10))

Simplifying this equation, we get:

y - 8 = -0.15(x + 10)

Option (c) has the same equation as above after simplification, so the answer is (c):

y-8=-0.2(x+10).

The results of the matrix operations are:

To compute each matrix sum or product, we first need to determine if the operation is defined. Then, we can use the rules of matrix arithmetic to find the result.

-2A is defined, since we can multiply a matrix by a scalar. To find the result, we simply multiply each element of A by -2:

-2A = [-2(2) -2(0) -2(-1); -2(4) -2(-3) -2(2)] = [-4 0 2; -8 6 -4]

B - 2A is defined, since both matrices have the same dimensions. To find the result, we first compute -2A as shown above, then subtract each corresponding element of B and -2A:

B - 2A = [7 -5 1; 1 -4 -3] - [-4 0 2; -8 6 -4] = [7-(-4) -5-0 1-2; 1-(-8) -4-6 -3-(-4)] = [11 -5 -1; 9 -10 1]

AC is undefined, since the number of columns in A (3) does not match the number of rows in C (2).

CD is defined, since the number of columns in C (2) matches the number of rows in D (2). To find the result, we multiply each row of C by each column of D and sum the products:

CD = [(1)(3)+(2)(-1) (1)(5)+(2)(4); (-2)(3)+(1)(-1) (-2)(5)+(1)(4)] = [1 13; -7 -6]

The scale factor of dilation is 3.

What is Dilation of a circle?

Dilation is the process of altering an object's or shape's size by reducing or enlarging its dimensions by a certain amount of scale. A circle with a radius of 10 units, for instance, is reduced to a circle with a radius of 5 units. This technique is applied in art and craft, photography, and logo design, among other fields.

Given : Radius of original circle A = 3

            Radius of Dilation circle B = 9

We know that, Scale factor of dilation =

Dimension of Dilation shape / Dimension of original shape

So, Scale factor of given dilation = Radius of Circle B / Radius of Circle A

                                                      = 9/3

                                                      = 3.

We can write tanz in terms of secz using the Pythagorean Identity as:
tanz = -sqrt(sec^2z - 1)

Part 1 of 2:
The Pythagorean Identity states that sin^2z + cos^2z = 1. We can use this identity to write tan^2z in terms of sec^2z.

First, let's rearrange the Pythagorean Identity to isolate cos^2z:
cos^2z = 1 - sin^2z

Next, we can divide both sides of the equation by cos^2z to get:
1 = sec^2z - (sin^2z)/(cos^2z)

Since tan^2z = (sin^2z)/(cos^2z), we can substitute this into the equation:
1 = sec^2z - tan^2z

Finally, we can rearrange the equation to isolate tan^2z:
tan^2z = sec^2z - 1

Now, let's consider the case when z is in Quadrant II. In this quadrant, tanz is negative and secz is negative. Therefore, we can write:
tanz = -sqrt(sec^2z - 1)

Part 2 of 2:
In the case when z is in Quadrant IV, tanz is negative and secz is positive. Therefore, we can write:
tanz = -sqrt(sec^2z - 1)

So, in both cases, we can write tanz in terms of secz using the Pythagorean Identity as:
tanz = -sqrt(sec^2z - 1)

If more than 400 sheets are duplicated, this equation will provide us with the overall expense, t.

A method that describes how two lines along both side of a sign connect each other. It typically contains an equal symbol and one variable. Similarly, 2x - 4 = 2. The variable x is present in the particular circumstance.

The equation that could be used to calculate the total cost, t, to copy p pages when p is greater than 400 is:

t = $5,000 + ($0.01 × (p - 400))

The base cost for copying the first 400 pages is $5,000. For each additional page above 400, the customer is charged $0.01 per page. Therefore, to calculate the total cost for copying p pages, we need to subtract 400 from p to determine the number of pages that are being charged at the additional rate, and then multiply that by $0.01 to determine the additional cost. This gives us:

Additional cost = $0.01 × (p - 400)

The total cost is then the sum of the base cost and the additional cost:

t = $5,000 + ($0.01 × (p - 400))

This equation will give us the total cost, t, for any number of pages greater than 400 that are copied.

The first monthly charge has about $78.78 allotted in the direction of reducing the principal.

The total buy charge of the house is $96,400 and the Spinoses made a 25% down payment, because of this they paid $96,400 x 0.25 = $24,100 in advance.

Therefore, the final quantity that they financed is $96,400 - $24,100 = $72,300.

They financed this amount at 5.50% for 30 years, which gives us the following method for calculating the monthly payment (P):

P = (r * PV) / (1 - (1 + r)^(-n))

in which:

Substituting the values, we get:

P = (0.00458 * 72,300) / (1 - (1 + 0.00458)^(-360))

P ≈ $410.66

We recognise that the monthly payment is $410.66 and we will calculate the interest portion of the primary monthly price as follows:

interest = balance * monthly interest price

interest = $72,300 * (5.50% / 12) ≈ $331.88

To calculate the amount of the primary monthly charge this is used to lessen the fundamental, we subtract the interest component from the total monthly payment:

$410.66 - $331.88 ≈ $78.78

Since the new poison kills half the population every 2 months, we can say that the remaining half will survive for another 2 months. Therefore, after 2 months, the rodent population will be half of 1,000,000, which is 500,000.

After another 2 months, the remaining half of the 500,000 will survive, which is 250,000.

After another 2 months, the remaining half of the 250,000 will survive, which is 125,000.

After 6 months, the rodent population will be 125,000.

Since 12 months is six 2-month periods, we can repeat this process again. After another 2 months, the rodent population will be 62,500.

After another 2 months, the rodent population will be 31,250.

After another 2 months, the rodent population will be 15,625.

There will be 22 blue signs at the end of the event.

The probability of an event can be determined by dividing the number of favorable outcomes by the total number of possible outcomes. For example, the probability of rolling a six on a standard six-sided die is 1/6, as there is only one favorable outcome (rolling a six) out of six possible outcomes (rolling a one, two, three, four, five, or six).

To solve this problem, we need to consider the factors that determine whether a house's sign will be flipped or not. A sign will only be flipped if the number of residents can divide the house number. For example, the sign on house number 12 will be flipped by the residents of that house because 12 is divisible by 2, 3, 4, and 6 (the factors of 12).

At the beginning, all signs are red, which means that none of the houses have had their sign flipped yet. Let's start with house number 1 and consider which houses will flip its sign.

For house number 1, its sign will not be flipped because 1 is only divisible by 1.

For house number 2, its sign will be flipped because 2 is divisible by 2.

For house number 3, its sign will not be flipped because 3 is only divisible by 1 and 3.

For house number 4, its sign will be flipped because 4 is divisible by 2 and 4.

For house number 5, its sign will not be flipped because 5 is only divisible by 1 and 5.

And so on, continuing this process for all 500 houses.

We can see that the signs on the houses with numbers that have an odd number of factors will end up blue, and the signs on the houses with numbers that have an even number of factors will end up red. This is because a factor always comes in pairs, except when the number is a perfect square, in which case the factor pair is identical (e.g. 4 has factors 1, 2, and 4, which is an odd number of factors).

So we need to count the number of integers from 1 to 500 that have an odd number of factors. These are the perfect squares, which are 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, and 484.

You should invest $26,100 in Stock Boll and $12,900 in Stock Coff to maximize your annual interest earned, and the maximum annual interest is $2,337.

To maximize your annual interest earned, you should invest as much money as possible in the stock with the higher interest rate, which is Stock Coff. However, there are two constraints that you need to consider: the buying limit on Stock Coff and the requirement to spend at least twice as much money on Stock Boll as Stock Coff.

Let's use algebra to solve this problem. Let x be the amount of money you invest in Stock Boll and y be the amount of money you invest in Stock Coff. Then we have the following equations:

x + y = $39,000 (the total amount of money you have to invest)
y <= $12,900 (the buying limit on Stock Coff)
x >= 2y (the requirement to spend at least twice as much money on Stock Boll as Stock Coff)

To maximize your annual interest earned, you want to maximize the expression 0.05x + 0.08y (the sum of the interest earned from Stock Boll and Stock Coff).

If you invest the maximum amount of money in Stock Coff ($12,900), then you have $39,000 - $12,900 = $26,100 left to invest in Stock Boll. This satisfies the requirement to spend at least twice as much money on Stock Boll as Stock Coff ($26,100 >= 2 * $12,900).

So the optimal solution is to invest $26,100 in Stock Boll and $12,900 in Stock Coff. The maximum annual interest earned is 0.05 * $26,100 + 0.08 * $12,900 = $1,305 + $1,032 = $2,337.

Therefore, you should invest $26,100 in Stock Boll and $12,900 in Stock Coff to maximize your annual interest earned, and the maximum annual interest is $2,337.

By solving the given equation, we can plot these two points on a coordinate plane, and then connect the points with a line. The formed line is the graph of the linear equation 3y=2x-7.

The coordinate plane is made up of two perpendicular lines called the x-axis and the y-axis. The x-axis, which is horizontal, is used to measure the distance of a point from the left and right side of the plane. The y-axis, which is vertical, is used to measure the distance of a point from the top and bottom of the plane.

To graph the equation 3y=2x-7, we first need to identify two points that satisfy the equation. We can do this by plugging in different values for x and solving for y. For example, when x=0, the equation becomes 3y=-7. Thus, one point that satisfies the equation is (0,-7). We can find a second point by plugging in a different value for x. For example, when x=2, the equation becomes 3y=-3. Thus, the second point that satisfies the equation is (2,-3).

Now, we can plot these two points on a coordinate plane, and then connect the points with a line. The formed line is the graph of the linear equation 3y=2x-7.

The solutions to this problem are y = 5 and y = -1/3.

Sure! The quadratic formula is a useful tool for solving equations of the form ax^2 + bx + c = 0. In this problem, we need to rearrange the equation so that it fits this form before we can use the quadratic formula.

First, let's multiply both sides of the equation by y to get rid of the fraction:

y^2 + 1 = 13y/6

Next, let's rearrange the equation so that it equals zero:

y^2 - 13y/6 - 1 = 0

Now we can use the quadratic formula to solve for y. The quadratic formula is:

y = (-b ± √(b^2 - 4ac))/(2a)

In this problem, a = 1, b = -13/6, and c = -1. Plugging these values into the quadratic formula gives us:

y = (-(-13/6) ± √((-13/6)^2 - 4(1)(-1)))/(2(1))

Simplifying the equation gives us:

y = (13/6 ± √(169/36 + 4))/2

Finally, we can solve for y by simplifying the square root and dividing by 2:

y = (13/6 ± √(289/36))/2

y = (13/6 ± 17/6)/2

y = (30/6)/2 or y = (-4/6)/2

11. The area of the floor is 24. 62 m²

12. The area of the enclosed string is 3, 853. 09cm²

13. The circumference of the circular mat is  4.39m

The formula for the area of a circle is expressed with the equation;

A = πr²

Where;

Also, circumference of a circle is 2πr

For a circumference of 17. 6m, we have

17. 6 = 2×3.14r

r = 2. 80

Substitute the value

Area = 3.14 × (2. 80)²

Area = 24. 62 m²

For the string, circumference = 220cm

220 = 2× 31.4r

r = 35. 03 cm

Area of the enclosed string = 3.14 × (35. 03)²

Area = 3, 853. 09cm²

For the circular mat

1.54 = 3.14r²

r² = 0. 49

Take the square root

r = 0. 7m

Circumference = 2× 3.14 × 0. 7 = 4.39m

Answer:

21.6 feet?

Step-by-step explanation:

8 percent of 3 is 0.24

0.24 x 90 is 21.6

All the real solutions of the equation are x=3, x=1, and x=-2. The rational root theorem states that any rational root of the equation x³-2x²-5x+6=0 can be written in the form p/q, where p is a factor of the constant term (6) and q is a factor of the leading coefficient (1). Therefore, the possible rational roots of the equation are: ±1, ±2, ±3, ±6

We can use synthetic division to test each of these possible roots until we find one that gives a remainder of 0.

1 | 1 -2 -5 6
 |   1 -1 4
 |_____________
 | 1 -1 -6 10

The remainder is not 0, so 1 is not a root of the equation.

-1 | 1 -2 -5 6
  |  -1  3 2
  |_____________
  | 1 -3 -2 8

The remainder is not 0, so -1 is not a root of the equation.

2 | 1 -2 -5 6
 |   2  0 10
 |_____________
 | 1  0 -5 16

The remainder is not 0, so 2 is not a root of the equation.

-2 | 1 -2 -5 6
  |  -2  8 14
  |_____________
  | 1 -4  3 20

The remainder is not 0, so -2 is not a root of the equation.

3 | 1 -2 -5 6
 |   3  3 0
 |_____________
 | 1  1 -2 6

The remainder is 0, so 3 is a root of the equation. We can use the quotient (1x²+1x-2) to find the remaining roots of the equation.

1x²+1x-2=0

Using the quadratic formula, we can find the remaining roots:

x = (-1 ± √(1²-4(1)(-2)))/(2(1))

x = (-1 ± √(1+8))/2

x = (-1 ± √9)/2

x = (-1 ± 3)/2

x = 1 or x = -2

Therefore, the real solutions using rational root theorem and quadratic formula are of the equation are x=3, x=1, and x=-2.
