Answer:

(i)

time to bounce in one direction is 0.75 sec

(ii)

time to bounce in other direction is 1.5 sec

(iii)

total time is 2.25 sec

Step-by-step explanation:

Time to bounce in one direction:

we can see that height is increasing till t=0.75sec

so, time to bounce in one direction is 0.75 sec

Time to bound in other direction:

we can see that height is decreasing from t=0.75 to 2=2.25 sec

so, time to bounce in other direction is 2.25-0.75

=1.5 sec

Total time :

We know that

total time = (time to bounce in one direction)+(time to bounce in other direction)

now, we can plug values

total time =0.75+1.5=2.25 sec

What is the answer for B and how did you get it ?
Orlov [11]
The length of side b is 52 because using the Pythagorean theorem we know that a² + b² = c². When we plug in the known values we would get 1521 + b² = 4225, and when we subtract 1521 from both sides we would get b = 52.

Will marl brainliest! Please help :,)
Gnom [1K]

Answer:

x= -4

Step-by-step explanation:

A line is 180 degrees. This means that we can use the equation

60+x+124=180

Simplify:

184+x=180

x= -4

We can check this answer by plugging it back in:

60 + (-4) +124 =180

180=180

I hope this helps!

Evaluate the polynomial when a. x = 0 and b. X = - 1.<br><br> x^2 - 8x - 7
jeka57 [31]

Answer:

(a) -7, (b) 2

Step-by-step explanation:

a) When x = 0,

=> x² - 8x - 7

=> (0)² - 8(0) - 7

=> 0 - 0 - 7

=> - 7

b) When x = -1,

=> x² - 8x - 7

=> (-1)² - 8(-1) - 7

=> 1 + 8 - 7

=> 9 - 7

=> 2
