Answer: Option D
Step-by-step explanation:
Note that the projectile height as a function of time is given by the quadratic equation
To find the maximum height of the projectile we must find the maximum value of the quadratic function.
By definition the maximum value of a quadratic equation of the form
is located on the vertex of the parabola:
Where 
In this case the equation is:
Then
So:

"<span>The sum of the squares of the digits is 26"
</span>10t + u = 26 ---->(1)
<span>"If the number is decreased by the number with its digits reversed, the result is 36"
u - 10t =36 -----> (2)
By subtracting the equation we can find t.
</span> u+10t = 26)<span>
-(u-10t=36)</span>
______________
0u +20t = 26 -36
---> 20t = -10
t= -10/20
t= -1/2
Inserting value t in (1)
10t + u = 26
10(-1/2) + u= 26
-5+u=26
u= 26+5 = 31
<span>
Using u and t in the original expression 10t+u express a positive number
10t+u
= 10(-1/2) +u
= -5 + 31
= 26
----> Proves this statement is true
</span>"The sum of the squares of the digits is 26"

Answer:
a. x = 8
b. m<B = 140
Step-by-step explanation:
a.
m<A = m<B
40 = 5x
x = 8
b.
m<A + m<B = 180
m<B = 180 - m<A
m<B = 180 - 40
m<B = 140
Answer: 34 miles
Step-by-step explanation:
First multiply the 2 miles she power walked by the 7 days. (14 miles)
Next, multiply the 5 miles by the 4 days. (20)
Add both numbers, 20+14=34 miles
