Answer:
-17x² + 3x
Step-by-step explanation:
(-8x² + 3) + (-9x² + 3x - 3)
-8x² + 3 - 9x² + 3x - 3
-17x² + 3x
Answer:
y=90(0.5)^x
The y-intercept is (0,90), so when x=0, y should be 90.
By replacing x=0 in all equations you get;
1)
y=90(2)^0 =90 accepted
2)
y=2(90)^0 =2 rejected
3)
y=0.5(90)^0 =0.5 rejected
4)
y=90(0.5)^0 =90 accepted
Since this is an exponential decrease,
y=90(2)^x is rejected.
Answer:A
Step-by-step explanation:
Answer:
50.24
Step-by-step explanation:
<u>→To find a circle's (compass) area, you must use the following formula:</u>
A = π
<u>→All you need to do is plug in 4 for the "r," (radius), and solve:</u>
A = π
A = π
<u>→When you multiply 16 by pi, we're going to use 3.14:</u>
A = 3.14(16)
A = 50.24
