4,320 books
$17,928+19.25b=$52,938+11b
where b represents books
Answer:
dunno
Step-by-step explanation:
Answer:
#1
<u>Sum of interior angles is 180:</u>
- y = 180 - (42 + 31) = 107
<u>The law of sines:</u>
- x / sin 107 = 11 / sin 42
- x = 11 sin 107deg / sin 42deg
- x = 15.72
#2
<u>The law of cosines:</u>
- cos 76 = (6² + 17² - x² )/2(6)(17)
- 204*0.24 = 325 - x²
- x² = 325 - 48.96
- x² = 276.04
- x = √276.04
- x = 16.61
#3
<u>Same as above:</u>
- 2*9.4*10*cos 20 = (10² + 9.4² - x²)
- 176.66 = 188.36 - x²
- x² = 188.36 - 176.66
- x² = 11.7
- x = √11.7
- x = 3.42
#4
<u>Sum of interior angles is 180:</u>
<u>The law of sines:</u>
- x / sin 34 = 15 / sin 94
- x = 15 sin 34 / sin 94
- x = 8.41
The y intercept is where the function passes through the y axis, so the “x” value needs to equal 0. We sub 0 in for “x” and solve for “y”.
f(0) = 9(0)^2 - 7 - 8(0)
f(0) = -7
Therefore the “y” coordinate would be -7
The ordered pair would be
(0, -7)
