Answer:
1
Step-by-step explanation:
f(x)=x^3+2x^2-x-1
f(1)=1^3+2(1)^2-1-1
f(1)=1+2*1-1-1
f(1)=1+2-1-1=3-1-1=2-1=1
Answer: h = 70ft
Step-by-step explanation: To find the height the ball reached after 2 seconds, substitute variable t for 2 and calculate height:




h = 70
<u>After 2s, the football reached a height of </u><u>70 feet</u><u>.</u>
Answer:
the correct answer is 7 and 9
<span>(1 + 5 ) x 2 = 12 1
+ [(5 x 2) – 2] = 10 </span>
<span>1 + [5 x (2 – 2)] = 1 [1
+ (5 x 2)] – 2 = 9</span>
<span>8 = 12 – [8 / (4 / 2)] 11 = 12 – [(8 / 4) / 2]</span>
<span>½ = [(12 – 8 ) / 4] / 2 20
= 6 x 4 – 4 x 5 </span>ß----can’t figure it out …sorry
<span>0 = 6 x
(4 – 4) x 5 100
= [(6 x 4) – 4] x 5</span>
<span>24 = [14 –(8 -2)] x 3 0=
(14 –8) – (2 x 3)</span>
<span>12 = [{14 – 8)
- 2] x 3 12
= 14 – [8 - (2 x 3)]</span>
The slope is 9/11 because if you use the formula (change in y)/(change in x), you would get -18/-22 and then if it were to be simplified, it would be 9/11
