Answer: B
Step-by-step explanation:
The equation is not yet in slope-intercept form(
). Simply subtract 2 from both sides to turn the equation into slope intercept form as
. For a line to be perpendicular to another, it must have an opposite reciprocal slope. A reciprocal is the fraction reversed, where the numerator is the denominator and vice versa. Thus, 3/4 would become 4/3. The opposite reciprocal of 3/4 would be -4/3.
The slope of the line given is 3/4. Thus, simply plug in the opposite reciprocal of 3/4 for the slope to get: . Then, because the line passes through -12, 1, plug those values in for x and y, respectively.
Thus, the equation of the line is , or B.

Answer:
8.90 seconds
Step-by-step explanation:
When the rocket hits the ground, its height ( <em>y</em> ) will be zero. This means we can write the equation as:
- 0 = -16x²+129x+119
So we need to <u>solve that equation</u>:
- a = -16
- b = 129
- c = 119
- x =
x₁ = -0.84
x₂ = 8.90
We discard x₁, as it is negative.
So the answer is x₂, 8.90 seconds.
Solution:- Answer is 19.33%
Annual percentage rate (APR) is the yearly rate for a price which have to pay for borrowing money through credit card.
Here Caleb has an offer from a credit card issue for i=0% APR for the first 30 days.
now, effective interest rate for n= 30 days
=
After 30 days APR =17.68%=0.1768
n=365-30=335 days
now the effective interest rate for n=335 days
=
=19.33%
So the effective interest rate for 365 days =0+19.33% =19.33%
So fourth option is correct.
