Answer:11.9 inches
Step-by-step explanation:
Circumference(c)=75inches
Pi=3.14
Circumference(c)=2 x π x radius(r)
75=2 x 3.14 x r
75=6.28 x r
Divide both sides by 6.28
75 ➗ 6.28=(6.28 x r) ➗ 6.28
11.9=r
Therefore radius=11.9 inches
There could have been one Grandma(One mom), one Mom(Another mom, and a daughter), and one Daughter(another daughter).
Given v=31 and s=0
<span>H(t) = -16t2 + vt + s
</span>
H(t) = -16t^2 + 31t
dH/dt = -32t + 31
<span>At the maximum height, dH/dt = 0
-32t + 31 =0
t = 31/32 = .96875
substitute back to H(t)
</span>
H( .96875) = 15.0 ft
ans is C
Answer:
Step-by-step explanation:
Johnny mows lawns after school and earns $10 per hour.
Let the number of hours h mows = x
Total earning of Johnny = $10x
If the earning is represented by the variable 'y' equation representing the total earnings will be.
y = 10x
Table for Input output values,
x 0 1 2 3 4
y 0 10 20 30 40

Answer:
A: 8x +24
B: not equivalent for any value of x
Step-by-step explanation:
<u>Part A</u>:
The factor of 4 on the outside of parentheses multiplies each term inside:
M = 4(2x) +4(6)
M = 8x +24 . . . . . expression equivalent to M
__
<u>Part B</u>:
Expressions M and N are not equivalent for any value of x. They are equivalent if their difference is zero or can be made to be zero. Subtracting N from M, we find the difference to be ...
M -N = (8x +24) -(8x +10) = 14
There is no value of x that will make the difference of 14 become zero.
