At 16 feet we have
16 = 3 + 30t - 16t^2
16t^2 - 30t + 13 = 0
t = [- -30 +/- sqrt(30^2 - 4*16*13) ] / 32
t = 1.20 , 0.68 seconds answer ( correct to the nearest hundredth)
Answer:
Step-by-step explanation:
We know that formula for average rate of change of a function from a to b is
Here f equals h and a =-3 b=5
h(a) = 
and
h(b) = 
h(b)-h(a) =
b-a = 5-(-3) =8
Hence average rate of change is
2/4+5/6+7/2=29/6-1/2=26/6=13/3=4 1/3
Answer:
50
Step-by-step explanation:
ABCD is quadrilateral. Sum of all the angles in a quadrilateral is 360. This means angle ADC will be 130.
ADE is a straight line. Angle ADC and angle CDE should sum up to 180. From here we can infer that angle CDE=x is 50
