(1) the diameter is 20 inches whats the radius? And whats the circumference?

Radius is half the diameter, Answer: 10 inches

Circumference is pi times the radius, Answer: 10π inches

I won't bother with the approximation, though this one is easy, 31.4159 inches.  I'll leave the rest of the calculator work to you if necessary.

(2) the diameter 11 inches whats the radius? And whats the circumference?

Radius half, Answer: 5.5 inches.   Circ: 5.5π inches

(3) the diameter 3.5 inches whats the radius? And whats the circumference?

Radius, 1.75 inches.  Circ: 1.75π inches

D=.5*a*t^2 - solving for a<img src="https://tex.z-dn.net/?f=d%3D.5%2Aa%2At%5E2" id="TexFormula1" title="d=.5*a*t^2" alt="d=.5*a*
Leviafan [203]

Answer:

\displaystyle a=\frac{d}{.5*t^2}

Step-by-step explanation:

<u>Equation Solving</u>

We are given the equation:

d=.5*a*t^2

It's required to solve it for a.

Swap sides to have the letter on the left side:

.5*a*t^2=d

Divide by .5*t^2:

\mathbf{\displaystyle a=\frac{d}{.5*t^2}}

The daytime temperature in Apple Valley is falling by 2.5 degrees each day. What will the net change in the daily temperature be
nexus9112 [7]

Answer:

Option D -17.5 degrees is correct answer

Step-by-step explanation:

Since a calendar week has 7 days. and temperature is falling by -2.5 daily.

So, On Day 1 Temperature is -2.5 degrees

On Day 2 Temperature is -2.5 + -2.5 = -5 degrees

On Day 3 Temperature is = -5 + -2.5 = -7.5 degrees

On Day 4 Temperature is = -7.5 + -2.5 = -10 degrees

On Day 5 Temperature is = -10 + -2.5 = -12.5 degrees

On Day 6 Temperature is = -12.5 + -2.5 = -15 degrees

On Day 7 Temperature is = -15 + -2.5 = -17.5 degrees

So, Option D -17.5 degrees is correct answer.
