Answer:
She bought 5 pounds.
Step-by-step explanation:
if she spent 10 dollars and its 2 dollars per pound that means that you have to divide 10 by 2 in order to get how many pounds you can buy for 10 dollars.
If you think about it if you want 2 pounds then you multiply 2 by 2 to get four because its 2 dollars per pound and you need 2 pounds. so since you don't know the number of pounds you fill in the blanks and do 10/2 to get 5.
The slope is -3 or -3/1 both work but you know that Becuase it says -3x this means that every 3 units you go down 3 units every one unit
Answer:
D) -50
Step-by-step explanation:
The answer is D.
Numbers below zero would be negative. This eliminates B and A, as they are positive.
Numbers above zero are positive.
<em>The answer is not C because that would be 25 degrees below zero</em>, not 50 below.
That leaves us with D. D is -50, which is also stated as "50 below zero".
So, our best answer would be D.
Let y = x^2 - 1
x^2 = y + 1
x = sqrt(y + 1)
so f^-1(x) = sqrt (x + 1) (answer)
Answer:
13.) 314.2 in²
15.) 181.5 ft²
Step-by-step explanation:
The area of a circle is found using the equation:
A = πr²
In this equation, "π" represents the number pi (3.14....) and "r" represents the radius (half the diameter).
For 13.), you have been given the radius. Thus, you can substitute it into the equation and solve for "A".
A = πr²
A = π(10)²
A = π x (100)
A = 314.2 in²
For 15.), you have been given the diameter. To find the radius, you need to divide this value by 2. Once you find the radius, you can plug it into the equation and simplify like above.
diameter = 15.2 ft
radius = 7.6 ft
A = πr²
A = π(7.6)²
A = π x (57.76)
A = 181.5 ft²
