Answer:
Step-by-step explanation:
take angle C as reference angle
using cos rule
cos C=adjacent/hypotenuse
cos C=21/75
cos C=0.28
C=
0.28
C=73.7 degree
Answer:
(x + 8)(x - 2)(4x - 1)
Step-by-step explanation:
Given that x = - 8 is a zero then (x + 8) is a factor
Divide f(x) by (x + 8) using Synthetic division
- 8 | 4 23 - 70 16
↓ - 32 72 - 16
---------------------------------
4 - 9 2 0
Quotient = 4x² - 9x + 2 = (x - 2)(4x - 1)
Thus
f(x) = (x + 8)(x - 2)(4x - 1)
He could have 30 dimes and 13 quartars
The correct option will be: A. 67%
<em><u>Explanation</u></em>
Given equation is:
, where
is the length of the film in minutes and
is the percentage of people finish watching the film.
Here, the length of the documentary is given as 95 minutes. So, we will <u>plug
into the above equation</u> and get....

<em>(Rounded to the nearest percent)</em>
So, the percentage of people in an audience who will finish watching a documentary that is 95 minutes long will be 67%
