Answer:
a) 5.6
Step-by-step explanation:
sin 22° = x/15
0.3746 = x/15
x = 5.62
Y=4x shows y as the total earnings and x as the number of windows
Answer:
what's the formula that you're supposed to apply the x to ?
Answer:
C = 96.71 inches
A = 745.06 in ^2
Step-by-step explanation:
d = 30.8
The radius will be 1/2 d= 1/2 (30.8) = 15.4
The circumference = pi *d
= pi * 30.8
=96.761
The area = pi * r^2
= pi * (15.4)^2
= 745.06011
<span>SALES: 5x² + 2x – 80
</span>- COST: 5x² – x + 100
= ------------------
PROFIT: 0x²+3x-180
(+3x because we subtracted a negative (-x), which is called adding, similarly taking away 100 from negative 80 is -180.)
Checking:
5x² + 2x – 80
5(500)²+2(500)-80 = 1,250,920
5x² – x + 100
5(500)² – (500) + 100= 1,249,600
Profit = 1,250,920 - 1,249,600 = 1,320
0(500)²+3(500)-180 = 1,320 YAY! {:-)
Double Checking:
5x² + 2x – 80
5(5000)²+2(5000)-80 = 125,009,920
5x² – x + 100
5(5000)² – (5000) + 100= 124,995,100
Profit = 125,009,920 - 124,995,100 = 14,820
0(5000)²+3(5000)-180 = <span>14,820</span> YAY! {:-)
