To solve this equation, start by noticing that you want to find t when P is 75%, or 0.75. Plug in 0.75 for P. Please see the attached screenshot for a step-by-step. The correct answer is 29.496 days.
EDIT 2: I actually was correct! You check the answer by substituting 29.496 for t in the original equation set equal to 0.75. It is 0.75. I had forgotten the negative sign when I checked.
Hello!
2X + 4 = 14
X = 5
2 * 5 = 10
10 + 4 = 14
I hope this helps, and have a nice day!
Answer:
76.3 degrees
Step-by-step explanation:
We use inverse cosine to find the angle.
arccos(1.9/8) = 76.26 deg
It’s D, because the x-value, 8, has two y-values, the 5 and 9. In order to be a function, each x-value has to have only one y-value.
