Answer: A & C
Step-by-step explanation:
g(x) = 8 means where is y = 8?
when we go to -4 on the x-axis, the y value there is 8. so this works!
when we go to 6 on the x-axis, the y value is 6. we were looking for 8. so this does not work.
when we go to 9 on the x-axis, the y value is 8. so this works!
A & C
If no repeats, there are 8×7×6×5×4×3×2×1=40320.
Step-by-step explanation:
The formula to find the final velocity, v of an object having an initial velocity , u , and acceleration , a , at time t is v=u+at
(a) v=u+at
Subtract u from both sides,
v-u=u+at-u
v-u=at
Dividing both sides by t.
![a=\dfrac{v-u}{t}](https://tex.z-dn.net/?f=a%3D%5Cdfrac%7Bv-u%7D%7Bt%7D)
(b) The relationship between the acceleration and time for a given initial and final velocity is given by "
![s=ut+\dfrac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cdfrac%7B1%7D%7B2%7Dat%5E2)
Where
s is the distance covered
t is the time
Hence, this is the required solution.
Answer:
<u>The correct answer is B. 145 in²</u>
Step-by-step explanation:
Let's recall that formula of the surface area of a pyramid:
S.A. = 1/2*(4 * side of the base * height) + side of the base ²
Replacing with the values provided, we have:
S.A. = 1/2*(4 * 5 * 12) + 5²
S.A. = 1/2 * 240 + 25
<u>S.A. = 145 in²</u>
<span>255 + 10m >= 650
10m >= 650 - 255
10m >= 395
m >= 395/10
m >= 39.5</span>
