Basically, you just have to use the formula of the volume of a cylinder, which is πr^2h, to find the answers
Sorry about the picture being blurry, really bad camera
3. Radius = 6 ÷ 2
= 3 cm
Volume = πr^2h
= π × 3^2 × 5
= 45π
31.+ addition
32. - subtraction
X= 48 is the correct answer. You can always plug in 48 back into the original equation and make sure it works.
48-23+84+48+23=180
Answer:
20. y = 3·3^x
21. y = (1/3)^x
Step-by-step explanation:
These exponential functions can be written in the form ...
y = a·b^x
where a is the value of y when x=0, and b is the common ratio between terms that have x different by 1.
__
20. The ratio is 9/3 = 3; the multiplier is 3 (the value of y when x=0), so the function is ...
y = 3·3^x
__
21. The ratio is (1/3)/1 = 1/3; the multiplier is 1, so the function is ...
y = (1/3)^x
_____
<em>Alternate solution</em>
Each of these can be written in a more compact form:
20: y = 3^(x+1)
21: y = 3^(-x)
