Answer: y= 5/2(x-2)^2 - 1

Step-by-step explanation:

y=a(x-2)^2 - 5

5=a(0-2)^2 - 5

10=a(-2)^2

10=a4

a=10/4 or 5/2

Answer:

1. $60

2. 600 Calories were burned

3. D

Step-by-step explanation:

1. $75 x .20=$15

75-15=$60

2. What I started with is 200/40=5 calories burned per min

60 plus 60=120

5x120=600

3. It's the only option that has something decreasing. and there is a -5 which means it's getting subtracted or its decreasing.

Can someone help me with this math problem ?? Pls it’s for my final !

Answer:

221.87 feet

Step-by-step explanation:

Given that,

A 525 ft cable runs from the top of an antenna to the ground.

The angle of elevation made by the ground to the top of an antena 25°

We need to find the height of the antenna.

Using trigonometry,

Hypotenuse, H = 525 ft

θ = 25°

So,

$\sin\theta=\dfrac{P}{H}\\\\P=H\sin\theta\\\\P=525\times \sin(25)\\\\P=221.87\ ft$

So, the height of the antenna is equal to 221.87 feet.
