b = -0.5 and a = 1. 2=3+-1. 1 to the third power is just 1, times 8 is 8. -0.5 to the third power is -0.125. -0.125 times 8 is -1. 8 - (-1) is 9. 36 times 1 is 36, times -0.5 is -18. 9-(-18) = 27. I hope this helps! Could I possibly get brainliest?
Answer:56/x
Step-by-step explanation:
that is the answer
Answer:
257.5 mph
332.5 mph
Step-by-step explanation:
The initial distance between the two planes is 960 miles, while the final distance (after t=1.5 h) is 75 miles, so the total distance covered by the two planes in 1.5h is
miles
Calling v1 and v2 the velocities of the two planes, we have the following equations:
(1)
--> velocity of plane 1 exceeds velocity of plane 2 by 75 mph
(2)
--> the total distance covered by the two planes is 885 miles (t=1.5 h is the time, and the products v1 t and v2 t represent the distance covered by each plane)
Substituting t=1.5 h, the second equation becomes:

By substituting (1) into this last equation, we find:

And substituting this back into eq.(1), we find

So, the speeds of the two planes are
257.5 mph
332.5 mph
Step-by-step explanation:
m and n are both located on the number line and are on the left of 0.
Therefore m and n are both negative reals.
m¹³ * n⁵
= (-)¹³ * (-)⁵
= (-) * (-)
= (+)
The answer is positive.
So we need to first do $75 + $35 = $110 then take $110 * "10% which is 0.1" 'so $110 *0.1 = $11 so $11 is the tax
so now again add $75 + $35 = $110 take $110 + $11 = $121
$121 is her final total
