Answer:

Write the problem as a mathematical expression.

y=−x²+18x−72

Rewrite the equation in vertex form.

y=−(x−9)²+9

Use the vertex form, y=a(x−h)2+k , to determine the values of a, h, and k.

a=−1

h=9

k=9

Find the vertex (h,k).

(9,9)

Michael just became a personal trainer and is finalizing his pricing plans. One plan is to charge $36 for the initial consultati

nexus9112 [7]

The cost will be same for one session. The cost will be $128.

Step-by-step explanation:

Given,

Initial consultation charges for Plan One = $36

Per session fee = $92

Let,

x be the number of sessions.

O(x) = 92x+36

Initial consultation charges for Plan Two = $86

Per session fee = $42

T(x) = 42x+86

For same cost;

O(x) = T(x)

$92x+36=42x+86\\92x-42x=86-36\\50x=50$

Dividing both sides by 50

$\frac{50x}{50}=\frac{50}{50}\\x=1$

Putting x=1 in T(x)

$T(1)=42(1)+86\\T(1)=42+86\\T(1)=128\\$

Putting x=1 in O(x)

$O(x) = 92(1)+36\\O(x) = 92+36\\O(x) = 128$

The cost will be same for one session. The cost will be $128.

A hiker climbs a 5-mile trail up a mountain in 2 hours. On the return trip downhill, she walks the same trail and returns to her

Ivahew [28]

Answer:

3.33 miles per hour

Step-by-step explanation:

The total distance traveled by the hiker is 5 * 2 = 10 miles, and the total time travelled is 2 + 1 = 3 hours.

So, to find the average speed of the entire trip, we can use the formula:

distance = speed * time

With distance = 10 and time = 3, we have:

10 = speed * 3

speed = 10/3 = 3.33 miles per hour.
