Answer:
In terms of pi: 164.5pi cm squared
Substituting pi for 3.14: 516.53 cm squared
Step-by-step explanation:
3.5^2 = 12.25pi
12.25*2 = 24.5pi
7pi*20 = 140pi
140 + 24.5 = 164.5pi
164.5*3.14 = 516.53
Answer:

Step-by-step explanation:
We are given the following in the question:
Let
be the proportion of the internet sales and
be the proportion of the store sale.
Hypothesis:
We have to conduct a hypothesis to check that the Internet sales are more than 10 percent higher than store sales.
Thus, we can design the null and alternative hypothesis as:

Alternate Hypothesis:
The alternate hypothesis states that the proportion of the internet sales is greater than the proportion of store sales by 10 percent.
Answer:
(−∞, ∞) and (−∞, ∞)
Step-by-step explanation:
One example (of many) might be y = 2x. The domain and range of this function are (−∞, ∞) and (−∞, ∞).
Sine is an odd function, meaning that sin(-x)=-sin(x) ∀ x ∈ R.
=>
sin(-t)-sin(t)=-sin(t)-sin(t)=-2sin(t)=-2a
