Answer:
Volume of the cylinder = 62.4 cm³
Step-by-step explanation:
Volume of a cylinder = area of base × height of the cylinder
Area of base = 15.6 square centimeters
Height of the cylinder = 4 centimeters
Volume of a cylinder = area of base × height of the cylinder
= 15.6 cm² × 4 cm
= 62.4 cm³
Volume of the cylinder = 62.4 cm³
The sum of -19ab and 7ab = -19ab + 7ab = -12ab
the sum of -11ab and -23ab = -11ab + (-23ab) = - 34ab
So
<span>Subtract the sum of -11ab and -23ab from the sum of -19ab and 7ab:
</span> (-12ab) - (-34ab) = -12ab + 34ab = 22ab
Answer
22ab
2000 is the y-intercept, it is the amount of money in the account initially.
<h3>
Exponential function</h3>
An exponential function is in the form:
y = abˣ
where a is the initial value of y, b is the multiplier, y, x are variables.
Let y represent the amount in the bank after x years.
Given the function y=2000(0.64)ˣ
Hence:
a = 2000, b = 0.64
0.64 = 1 + x
x = -0.36 (36% decrease)
2000 is the y-intercept, it is the amount of money in the account initially.
