Answer:
5.3-1.45=3.85
Step-by-step explanation:
she has 3.85 miles left to go because she already ran 1.45 and if you subtract that from the 5.3 you get 3.85 left to run.
Area would be 15 if base is 6m and height is 5m
So 6*4=24
5*4=20
Area would be 240 for the 2nd answer
240/15=16
The area is 16x bigger
Answer:
Perimeter: 14.2
Area: 9.2
Step-by-step explanation:
Simple times for area
simple plus for perimeter
3x^2 + 6x - 10 = 0
x = [-6 +/- sqrt(^2 - 3*3*-10)] / 2*3
= 1.08 and -3.08
Other x -intercept is (-3.08,0)
The speed of the ball is
ds/dt = 32t
At t =1/2 s
ds/dt = 16 ft/s
The distance from the ground
50 - 16(1/2)^2 = 46 ft
The triangles formed are similar
50/46 = (30 + x)/x
x = 345 ft
50 / (50 - s) = (30 + x)/x
Taking the derivative and substituing
ds/dt = 16
and
Solve for dx/dt
