Answer:
A=30 B=90 C=60
Step-by-step explanation:
A=30 C=60 B=90
For this case we have the following equation:
H (t) = - 16t ^ 2 + 28t
When the dolphin finishes a jump, then the height is equal to zero.
We have then:
-16t ^ 2 + 28t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 1.75 s
Therefore, the dolphin takes 1.75 seconds to make a jump.
Answer:
it will take for the dolphin to make one jump about:
t = 1.75 s
The formula for slope is
m= (y₂-y₁)/(x₂-x₁)
you can plug in the points that you are given to find the slope
m= (-1-2)/(2-(-4)
m= -3/6
the slope is -3/6 which reduced to -1/2
so the answer would be
c) -1/2

Answer:
9 × 7 + (8 - 5) = 66
Step-by-step explanation:
9 × 7 + 8 - 5 = 66
Applying the order of operations (PEMDAS);
The parenthesis would go to 9 × 7 + (8 - 5) = 66
