Answer:
It is the second choice.
Step-by-step explanation:
Divide both side by pi r squared. Boom.
We are given that the distance light travel is:
9.45 x 10^15 meters / year
And that there is:
3.15 x 10^7 seconds / year
So the distance light travels per second is:
distance = (9.45 x 10^15 meters / year) * (1 year / 3.15 x
10^7 seconds)
<span>distance = 3 x 10^8 meters / second</span>
I think that the correct answer is f(-1)=-8 and f(0)=-5
I hope this helps :D
Answer:
B
Step-by-step explanation:
Using the rule of exponents
= 
Given
y = 12 × 
← substitute x = - 2 into the expression
y = 12 × 
= 12 × 
= 12 × 
= 
= 
→ B
First of all, i will start by comparing the given values. That will be;
7/2 meters=$231/4
1 meter= x
I represented the unknown value by x. Anyway, you have to cross and multiply. SO 7/2 multiplies x to give you 7/2x and 1 multiplies 231/4 to give you 231/4. That will be;
7/2x=231/4
Divide the both sides by 7/2.
7/2x÷7/2=231/4÷7/2
When dividing fractions, the division sign changes to a multiplication sign and the fraction on the right turns upside down. So;
x=231/4 x 2/7
x=231/14
x=$33/2.
Hope i helped.
