If 7 pounds of candy cost $16.17. How much does 1 pound of candy cost?

The quadratic equation in vertex form is y = -(x - h)² + k

The parabola passed through points (-1, -3), (0, 0), (1, 1), (2, 0) and so on

For a vertical parabola, the vertex form of the equation is written as

y = a(x - h)² + k    

where:

a = 1/4p

h and k are points of the vertex = v(h, k)

The vertex

v (h, k) = (1, 1)

h = 1

k = 1

y = a(x - 1)² + 1  

using point (0, 0)

0 = a(0 - 1)² + 1

-1 = a

hence a = -1  

the equation is written as y = -(x - h)² + k  

The points the graph passed is read from the graph to be

(-1, -3), (0, 0), (1, 1), (2, 0) and so on

I haven't figured out the last yet and the fraction one

The farmer needs to sow 135 acres of corn and wheat, and 45 acres of wheat.

A linear equation is the algebraic expression y=mx+b. B is the y-intercept, and m is the slope. A "linear equation in two variables" is the term used to describe the previous sentence, where y and x are variables. Two variables make up bivariate linear equations. Examples include the linear equations 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. It is said to be linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.

given

180 acres total land area

The corn acres should be C.

The wheat acres should be W.

A 180-acre property is planted with wheat and corn by a farmer.

Equation 1: C + W = 180

Corn is grown on three times as many acres as wheat:

Equation 2 is created by substituting C = 3W into Equation 1. The result is:

45 acres is W.

For corn, 135 acres equals C.

Answer:

28 units

Step-by-step explanation:

Firstly, we can see that the vertical sides are 9 units each.

To get the diagonal sides, we can turn the ends into right triangles, which we can then use with the Pythagorean Theorum.

To make the top side into a triangle, we would draw a horizontal line connecting points (-1, 3) and (3, 3). This creates a right angle which is essential when using the Pythagorean Theorum.

A^2 + B^2 = C^2

We can plug in values for the Pythagorean Theorum because we can see that going across horizontally from point (-1, 3) to (3, 3), there are 4 units in between the two points. This will be our A value. We will do the same but vertically from points (3, 6) to (3, 3). The 3 units between the two points will be our B value. Now, we can plug in our values into the Pythagorean Theorum to find side C, the hypotenuse.

4^2 + 3^2 = C^2

16 + 9 = C^2

25 = C^2

√25 = C

C = 5

Now that we know the diagonal value of the side, we also know the same diagonal value of the bottom side. When you add all four sides together,

9 + 5 + 9 + 5 = 28

you get 28, which is the perimeter of the parallelogram.

So,  a 72-month loan with a 2 annual simple interest rate is the loan choice that would need her to repay the least amount of money.

An interest rate informs you of how much borrowing will cost you and how much saving will pay off. Therefore, the interest rate is the amount you pay for borrowing money and is expressed as a percentage of the entire loan amount if you are a borrower.

According to the information provided, a 72-month loan with a 2 annual simple interest rate is the loan choice that would require her to repay the least amount of money. This is because the amount she would have to pay will be the least compared to other loan options.

[tex]Loan = 72 months (2per cent of $6,000)\\Loan = 120 for 72 months\\Loan =$8,640\\[/tex]

Step-by-step explanation:

The bicycle tire needs an amount of 115 pumps to be fully inflated. (Correct choice: B)

In this problem we need to determine the number of pumps needed to inflate the bicycle tire at maximum pressure, this number (n) is equal to the maximum capacity of the tire (V), in ounces, and the mass added by a single pump (p), in ounces:

n = V / p

If we know that V = 640 oz and p = 5.6 oz (1 lb = 16 oz), then the number of pumps is:

n = 640 oz / 5.6 oz

n = 114.286

n = 115

An amount of 115 pumps are needed to inflate the bicycle tire to maximum pressure.

The word used to remember the 3 trigonometric ratios sine, cosine, and tangent is SOH-CAH-TOA

We know that in right triangle for an angle θ, the trigonmetric ratios are:

sin(θ) = opposite side of θ/ hypotenuse

cos(θ) = adjacent side of θ / hypotenuse

tan(θ) = opposide side of θ / adjacent side of θ

cot(θ) = 1/tan(θ)

sec(θ) = 1/cos(θ)

cosec(θ) = 1/sin(θ)

The word 'SOH-CAH-TOA' is used to remember the sine, cosine, and tangent ratios in a right triangle.  

SOH means, Sine = Opposite side / Hypotenuse.

CAH means, Cosine = Adjacent side / Hypotenuse.

TOA means, Tangent = Opposite side / Adjacent side

The statement regarding the region of rejection for a 5% significance level would be true is the region of rejection lies between the z-scores -2 and 2.Option B is correct.

A collection of values for the test statistic for which the null hypothesis is rejected constitutes a critical zone, sometimes referred to as the region of rejection. For example, if the observed test statistic is in the critical range, the null hypothesis is rejected and the alternative hypothesis is accepted.

Further the rejection zone is the area in which we have sufficient data to reject the null hypothesis if our test statistic falls within it. The rejection area, for the right-tailed test, for instance, is any value bigger than the critical value, or c 1 .

Therefore, the interval that causes the null hypothesis H 0 to be rejected in a hypothesis test is known as the region of rejection and is measured in the sampling distribution of the statistic under examination.

It may not tell you anything. You have to be careful how you think about the answer to this. An ordered pair is just that: it describes an x and y value and that is really all that it does.

However it may also be used to describe the solution to a system of equations which cross in one place. For example, if you plot

y = x + 1

If she doubles the area of her lot, it should be 2x^2.

But how do you get that?

The answer is that the sides have now increased to √2x

How did I get that, and why did I choose it?

Answer:

x = 25

Step-by-step explanation:

The top angle is the supplement of 3x - 10

180 - (3x - 10) = -3x + 190

The sum of the angles in a triangle is 180

(-3x + 190) + (25) + (x + 15) = 180

Combine like terms

-2x + 230 = 180

Subtract 230 from both sides

-2x = -50

Divide both sides by -2

x = 25

When you and your 3 friends decide to split the bill of $36 evenly and you leaving a 12% tip on your part, you pay a total of $13.32.

Therefore the answer is 13.32 dollars.

When you and your 3 friends decide to split the bill evenly, each person is responsible for paying 1/4 of the total bill. The total bill is $36, so each person is responsible for paying

$36 / 4 = $9

You also decided to leave a 12% tip on your part, so you need to calculate 12% of $36. To do this, you can multiply $9 by 0.12

$36 × 0.12 = $4.32  

So, you are responsible for paying $9 + $4.32 = $13.32

So you are responsible for paying $13.32 in total.

Because 5 is represented by the polynomial 5x0, the answer is yes.

A polynomial is a mathematical statement made up of coefficients and indeterminates that uses only the operations addition, subtraction, multiplication, and powers of positive integers of the variables.

An example of a polynomial of a single indeterminate x is x² − 4x + 7.

An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial (No division operation by a variable).

Sums of terms of the form kxn, where k is any number and n is a positive integer, make up polynomials.
