The answer is D because if you go to 150 and line it up you will get 7 as you answer
Answer: The height and the width is a number that would be multiplied by itself like 5x5=25. The answer to this question would be 12 as the width and the height.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given function is,
f(x) =
Equation form of the function will be,
y =
Interchange x and y,
Solve for y,
y = 2x + 1
Therefore, inverse of the function 'f' will be,
Now = 2 - [2x + 1]
= -2x + 1
Value of = f(2x + 1)
From the given function,
f(2x + 1) =
= x
Therefore, value of
Answer:
she purchased 6 compact discs
Step-by-step explanation:
13.95 × 6 + 1.95= 85.65
Solution: (1)The interval notation of is .
Explanation:
The product of two expression is positive if and only if both are positive or both are negative.
case 1: and
Then and
From above conditions .
case 2: and case 2:
Then and
From above conditions .
By case 1 and 2 it is conclude that the interval notation of is .
Solution: (2) The interval notation of is .
Explanation:
The relative equation of the above inequality is
Equate each factor equal to 0. The zeros of above equation is -7,-1 and 1. These points divides the number line in 4 parts or intervals. The any value from those interval to check the inequality. If the test point satisfies the equality then that interval is the solution of the inequality.
By the above process the interval notation of is .
Solution: (3) The ball is lower than the building for .
Explanation:
The height of the ball is given by the equation and the height of the building is 280ft.
The ball is lower than the building if the height of the ball is less than 280ft, i.e., .
The time is always positive, so the first factor 16t is always positive. Since first factor is positive and the product of both factors is less than zero, therefore the second factor (-t+3) is always less than zero.
Therefore, the ball is lower than the building for .
