The answer for it has to be 5 because 5*8=40 and 5*10=50 so its 5
Step-by-step explanation:
A and r is 3, hope it helps......
P=2l+2w ---> P=2(11)+2(8.5) -- Substitute
P=2(11)+2(8.5) ---> P=22+17 -- Multiply
P=22+17 ---> P=39 inches -- Add
Answer:
(a) t = 7 sec approximately; (b) t = 6 sec
Step-by-step explanation:
(a) Set h(t)= -16(t-3)^2 + 288 = 0 and solve for t:
16(t-3)^2 = 288
After simplification, this becomes (t - 3)^2 = 18, or t - 3 = ±3√2.
Because t can be only zero or positive, t = 3 + 3√2 = 7 seconds
(b) Solve h(t)= -16(t-3)^2 + 288 = 150:
-16(t-3)^2 = - 162
or (t - 3)^2 = 10.125, or
t - 3 = ±3.18, or, finally, t = 6.18 sec (discard t = -0.18 sec)
Well the 384 part is the harder part because it is a more complex number (for humans) so after you find out what 4x384=(1536) then 4x5000 is simple and you just add the two answers together.
