For f(x)=2x, find f(9)

Answer:

24

Step-by-step explanation:

The sum of the three angles in a triangle is always 180 degrees.

Let x be the measure of the third angle.

Then we have:

102 + 54 + x = 180

Simplifying the left side:

156 + x = 180

Subtracting 156 from both sides:

x = 180 - 156

x = 24

Therefore, the measure of the third angle is 24 degrees.

Answer:

the answer in this is letter A

Kevin buys a motorcycle for $11,000 with an annual interest rate of 10.75% and a 108-month term, his monthly payments will be $200.39 if he makes a down payment of $2,300.

The monthly payment for a $11,000 loan with an annual interest rate of 10.75% and a 108-month term can be calculated using the formula for the present value of an annuity:

[tex]PV = PMT * (1 - (1 + r/n)^{-n*t}) / (r/n)[/tex]

where PV is the present value of the loan, PMT is the monthly payment, r is the annual interest rate, n is the number of compounding periods per year, and t is the loan term in years.

With a down payment of $2,300, the loan amount is reduced to $8,700 ($11,000 - $2,300). Plugging in the values, we get:

PV = $8,700

r = 0.1075

n = 12 (since payments are monthly)

t = 9 (108 months / 12)

PMT = $200.39 (rounded to the nearest cent)

Kevin needs to pay off a loan of $11,000, which he plans to do over a period of 108 months with an annual interest rate of 10.75%. However, if he makes a down payment of $2,300, his loan amount will be reduced to $8,700. Using the formula for the present value of an annuity, we can calculate his monthly payments, which come out to be $200.39. Therefore, his monthly payments will be $200.39 if he makes a down payment of $2,300.

Using probability distribution, we can find that P(x=9) = 0.13

To determine the chance of each potential value that a random variable might have, a function known as the probability distribution is used. A discrete probability distribution can be defined using a probability distribution function and a probability mass function.

Both a probability density function and a probability distribution function can be used to define a continuous probability distribution. The geometric, Bernoulli, binomial, and Bernoulli distributions are examples of probability distributions.

Now in the given question,

P(3) = .04

P(6) = .62

P(12) = .21

Now,

p (3) + p (6) + p (9) + p (12) = 1

0.04 + 0.62 + p(9) + 0.21 = 1

p(9) = 0.13

Answer:

C. 10 sandwiches

Step-by-step explanation:

Each section of a box plot makes up 25% of it. Since Q1 is marked by $18, that means 25% of 40 sandwiches can be bought with it. So, [tex]\frac{40}{4}[/tex] = 10.

The question involves a basic division operation in Mathematics. Without the cost of a sandwich, it's impossible to answer. If provided, just divide the total money by the price of a sandwich to find the number that can be purchased.

The student's question involves simple division, which is a topic under the subject of Mathematics. To determine how many sandwiches one can afford with $18, it is necessary to have the cost of one sandwich. Unfortunately, without the given price of a single sandwich as indicated in the boxplot, we cannot compute the answer.

But if we are provided the cost of a single sandwich, we would simply divide the total amount of money ($18) by the cost of a single sandwich. This would give us the total number of sandwiches affordable with the given amount of money.

Assuming a sandwich costs $2, here is how the computation would be: $18 ÷ $2 = 9 sandwiches. So, with $18, we could afford 9 sandwiches at $2 each.

The equivalent expression is option D)  [tex]81/m^7.[/tex]

What is the equivalent expression?

In mathematics, an equivalent expression is one that has the same value or meaning as another expression, even though it may look different. In other words, two expressions are equivalent if they simplify to the same value or form.

To simplify the expression [tex](3m^{(-4)})^3 * (3m^5)[/tex], we need to apply the power of a power property of exponents, which states that [tex](a^b)^c = a^(b*c)[/tex].

Using this property, we can rewrite [tex](3m^{(-4)})^3[/tex] as [tex]3^3[/tex] * [tex](m^{(-4)})^3 = 27 * m^{(-12)[/tex]. Similarly, we can rewrite (3m⁵) as 3 * m⁵.

Substituting these values back into the original expression, we get:

[tex](3m^{(-4)})^3 * (3m^5) = 27 * m^{(-12)} * 3 * m^5[/tex]

[tex]= 81 * m^{(-12+5)[/tex]

From the system of equations one apple pie costs $6 and one lemon meringue pie costs $7.

A group of equations that need to be solved concurrently is referred to as a system of equations. The values of the variables that satisfy each and every one of the system's equations are the solutions to the corresponding equations. Systems of equations can be solved using a variety of techniques, such as substitution, elimination, and graphing. Systems of equations can be used to simulate situations in business, science, and engineering when there are several variables at play. Systems of differential equations, linear equations, and quadratic equations are a few examples of systems of equations.

Let us suppose the cost of the apple pie = x.

Let us suppose the cost of the meringue pie = y.

Given that, Dan sold 14 apple pies and 9 lemon meringue pies for a total of $147.

14x + 9y = 147

For Jenny:

8x + 12y = 132

Using the elimination method we have:

Multiplying Dan's equation by 4 gives:

56x + 36y = 588

Multiplying Jenny's equation by 3 gives:

24x + 36y = 396

Subtracting the second equation from the first:

32x = 192

x = 6

Substitute the value of x in equation:

14(6) + 9y = 147

84 + 9y = 147

9y = 63

y = 7

Hence, from the system of equations one apple pie costs $6 and one lemon meringue pie costs $7.

The equation are: x = -1 radians (-57.3°) and x = 11 radians (626.9°).

To solve this equation, use the identity sin2x + cos2x = 1 and apply it to the left side of the equation.

2 sin2x + 20 cos x = 6

2 (1 - cos2x) + 20 cos x = 6

2 - 2 cos2x + 20 cos x = 6

2 cos2x - 20 cos x + 2 = 6

cos2x - 10 cos x + 1 = 0

Next, solve the resulting quadratic equation using the quadratic formula: x = [-b ± √(b2 - 4ac)]/2a. In this case:

x = [-(-10) ± √((-10)2 - 4(1)(1))]/2(1)

x = [10 ± √(100 - 4)]/2

x = [10 ± √(96)]/2

x = (10 ± 4√6)/2

x = (10 ± 12)/2

x = 5 ± 6

We then use the interval [0,2π) to calculate the exact radian values for x. The two solutions in this interval are:

x = 5 - 6 = -1

x = 5 + 6 = 11

For reference, the angle corresponding to -1 radians is -57.3° and the angle corresponding to 11 radians is 626.9°.
To check the solution, graph the two sides of the equation on Desmos, with the interval [0,2π). The graph will show the two points of intersection (marked with circles) which correspond to the two solutions.

To solve this problem, we can use a system of equations. Let's call the number of main-floor seats x and the number of balcony seats y.
The first equation can be written as:
10x + 4y = 5800
The second equation can be written as:
0.3x + 0.5y = 1900

Now we can use the elimination method to solve for one of the variables. Let's multiply the second equation by -10 to eliminate the x variable:
-3x - 5y = -19000
Adding the two equations together gives us:
7x - y = 3900
Now we can use substitution to solve for one of the variables. Let's solve for y in the first equation:
y = (5800 - 10x)/4
And substitute this value into the second equation:
7x - (5800 - 10x)/4 = 3900
Multiplying both sides by 4 gives us:
28x - 5800 + 10x = 15600
Solving for x gives us:
38x = 21400
x = 563.16
And plugging this value back into the first equation to solve for y gives us:
y = (5800 - 10(563.16))/4
y = 609.21
So there are approximately 563 main-floor seats and 609 balcony seats.

Answer:

Let x be the number of additional miles Tammy needs to run this week to reach her goal of at least 10 miles per week.

To determine the inequality, we can start with the given information and use the inequality symbol for "greater than or equal to" (≥):

4.5 + x ≥ 10

This inequality states that the sum of the distance Tammy has already run this week (4.5 miles) and the additional distance she still needs to run (x miles) must be greater than or equal to 10 miles in total for her to reach her goal.

To solve for x, we can start by subtracting 4.5 from both sides of the inequality:

x ≥ 10 - 4.5

Simplifying, we get:

x ≥ 5.5

Therefore, Tammy must run at least 5.5 more miles this week to reach her goal of at least 10 miles per week.

[tex]\dfrac{\text{d}y}{\text{d}x}=4x-1[/tex]

Step-by-step explanation:

Differentiating from First Principles is a technique to find an algebraic expression for the gradient at a particular point on the curve.

[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Differentiating from First Principles}\\\\\\$\text{f}\:'(x)=\displaystyle \lim_{h \to 0} \left[\dfrac{\text{f}(x+h)-\text{f}(x)}{(x+h)-x}\right]$\\\\\end{minipage}}[/tex]

The point (x + h, f(x + h)) is a small distance along the curve from (x, f(x)).

As h gets smaller, the distance between the two points gets smaller.

The closer the points, the closer the line joining them will be to the tangent line.

To differentiate y = 2x² - x + 3 using first principles, substitute f(x + h) and f(x) into the formula:

[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{2(x+h)^2-(x+h)+3-(2x^2-x+3)}{(x+h)-x}\right][/tex]

Simplify the numerator:

[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{2x^2+4xh+2h^2-x-h+3-2x^2+x-3)}{x+h-x}\right][/tex]

[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{2x^2-2x^2+x-x+3-3+4xh+2h^2-h)}{h}\right][/tex]

[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{4xh+2h^2-h)}{h}\right][/tex]

Separate into three fractions:

[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[\dfrac{4xh}{h}+\dfrac{2h^2}{h}-\dfrac{h}{h}\right][/tex]

Cancel the common factor, h:

[tex]\implies \displaystyle \dfrac{\text{d}y}{\text{d}x}=\lim_{h \to 0} \left[4x+2h-1\right][/tex]

As h → 0, the second term → 0:
