Answer:

1,256 dm^2 and 400π dm^2

Step-by-step explanation:

The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2

Solve the following equation for y.<br>x-5y=-18<br>​
olganol [36]

Answer:

y=15x+185

Step-by-step explanation:

Step 1: Add -x to both sides.

x−5y+−x=−18+−x

−5y=−x−18

Step 2: Divide both sides by -5.

−5y−5=−x−18−5

y=15x+185

In ∆abc, m∠cab = 2x and m∠​acb = x + 30. if line segment a b is extended through point b to point d, m∠​cbd = 5x − 50. what is t
Allisa [31]
The answer is option "3, 40".

<span>m∠cab = 2x
m∠​acb = x + 30
m∠​cbd = 5x − 50
Now,
</span>m∠cab + m∠​acb = m∠​cbd 
2x+x+30 = 5x-50
2x+x-5x = -50-30
-2x = -80
x = 40

What is the equation of the exponential graph shown?
Evgesh-ka [11]

Answer:

  • f(x) = 100*(1/2)ˣ

Step-by-step explanation:

<u>Exponential function is:</u>

  • f(x) = a*bˣ

<u>Use two points on the graph to determine the value of a and b:</u>

  • (0, 100), (1, 50)

<u>Find the values of a and b:</u>

  • f(0) = a*b⁰ = a = 100
  • f(1) = a*b¹ = ab = 100b = 50 ⇒ b = 50/100 = 1/2

<u>The function is:</u>

  • f(x) = 100*(1/2)ˣ
