Answer:

23.55

Step-by-step explanation:

We know it's three quarters of a circle since the angle is 270°

Therefore we can calculate like a normal circle and multiply by \frac{3}{4}.

The formula for calculating the circumference is 2 times pi times the radius or 2\pi r .

\pi=3.14\\2\times\pi=6.28\\6.28\times5=31.4\\31.4\times\frac{3}{4}=23.55

8^x times 2^(4-x) = 1<br> Find x.<br> With detailed steps.
Dafna1 [17]

Answer: x= -1

Step-by-step explanation:

In mathematics when you have bases that are the same while multiplying you add the powers. In this case we do not have the same bases so we are going to make it look like 8 is 2. So we sort of simplify it. So we get 8 and put into like 2^4. We do not eliminate the power x that was already there though. So we will have 2^4x × 2^4-x. So like I said earlier we add the powers. Soo we will have

  1. 4x +4-x
  2. 4x-x=1
  3. 3x+4-4 =1-4
  4. 3x/3 = -3/3
  5. x= -1

Is the equation y=4x+1 proportional? *<br> Yes<br> No
Mumz [18]

Answer:

No

Step-by-step explanation:

y = 4x + 1 is not a direct variation. Direct variations have the form y = kx. So y = 4x would be a direct variation (k=4), but not y = 4x+1
