Answer:
Step-by-step explanation:
Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...
x + (x+40) = 1180
2x = 1140 . . . . subtract 40
x = 570 . . . . . .divide by 2
x+40 = 610 . . . . the speed of the faster plane
The two speeds are 570 mph and 610 mph.
H(d)=height from water
when he reaches the water, his height from water=0
so set the equation equal to zero and solve
0=-d^2+2d+24
multiply both sides by -1 for ease
0=d^2-2d-24
now find what 2 factors of -24 add up to -2
answer is -6 and 4
0=(d-6)(d+4)
set each to zero
d-6=0
d=6
d+4=0
d=-4
you cannot have negative distance because that means he hasn't jumped yet so get rid of this number
d=6
answer is 6 meters
Answer:
c
Step-by-step explanation:
Answer:
A = 0
Step-by-step explanation:
3 times 0 =0
0 + 8 = 8
8 divided by 2 = 4
4 is less than 10
