Answer:

So the vertex is (3,36)

Step-by-step explanation:

y = a (x-h)^2 +k is the vertex form of a parabola

(h,k) is the vertex

Assuming the equation is

y = (x-3)^2 +36

h = 3 and k = 36

So the vertex is (3,36)

A museum groundskeeper is creating a semicircular statuary garden with a diameter of 29 feet. There will be a fence around the g

Jlenok [28]

Answer:

The fence will cost $330.09

Step-by-step explanation:

First we have to calculate the perimeter of the semicircle for that we use the following formula:

d = diameter = 29ft

s = perimeter of semicircle

π = 3.14

s = d * 1/2 * π

we replace the values that we know

s = 29ft * 1/2 * 3.14

s = 45.53ft

Now we multiply the number of feet by the price of 1 foot of fence

45.53 * $7.25 = 330.0925

Rounding to the nearest hundredth

$330.0925 = $330.09

Which equation would you use to solve this problem: Laura bought 4 1/3 bushels of apples for $16. How much did each bushel cost?

loris [4]

Answer: $3.69

Step-by-step explanation:

Laura bought 4 1/3 bushels of apples.

Firs convert this to an improper fraction for easier calculation:

= 13/3 bushels of apples.

If cost $16 altogether, individually they must cost:

= Cost / Quantity purchased

= 16 ÷ 13/3

= 16 * 3/13

= $3.69

<em>Note: You can divide by a fraction by multiplying the inverse of that fraction. </em>

-y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

Dimas [21]

Answer:

Part 1) $x=2.375$

Part 2) $y=3.3$

Part 3) $k=6.7$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Part 1) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

we know that

$y*x=k$

substitute the given values and solve for x

$8*x=19$

$x=19/8$

$x=2.375$

Part 2) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?

we know that

$y*x=k$

substitute the given values and solve for y

$y*7=23$

$y=23/7$

$y=3.3$

Part 3) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?

we know that

$y*x=k$

substitute the given values and solve for k

$6.7*1=k$

$k=6.7$
