Answer:
-32ft/s
Step-by-step explanation:
Given the function of the height expressed as h(t) is –32t² – 16t + 9.
Rate of change in height is the velocity and expressed as;
v(t) = d(h(t))/dt = -64t - 16
at t = 1sec
v(1) = -64(1)- 16
v(1) = -80ft/s
at t = 1.5secs
v(1.5) = -64(1.5)- 16
v(1.5) = -96-16
v(1.5) = -112ft/s
The average rate of change in the height of the ball between 1 and 1.5 seconds = -112-(-80) = -112+80 = -32ft/s

Malik got a 200 cafe gift on January 1. He always orders decaf mochas which cost 5 each. At the end of January, maliks gift card has 125 left. Write an equation with x as your variable.
Answer:
200 - 5x = 125
Step-by-step explanation:
Let the number of orders made by Malik in the month of January = x
Each order costs = $5
Total cost of decaf mochas in one order = $5x
Malik had cake gift on 1st of January = $200
Amount of money left with Malik at the end of January = $125
Therefore, equation representing this situation will be,
200 - 5x = 125
A box has 3 pencils, 5 pens, and 4 markers. What is the probability of randomly pulling out a marker, then after putting it back your friend

Mrs. Roberts sewed m shirts using 2 yards of cloth for each shirt. She also sewed (m+2) dresses, using 5 yards of cloth for each dress. A) How much cloth did she use altogether? Give your answer in terms of m. B) If m= 7, find how much more cloth she used to sew the dresses than the shirts.
Answer:
7m + 10
31 yards
Step-by-step explanation:
Shirts :
Number of shirts sewed = m
Yards of cloth used per shirt = 2 yards
Number of dresses sewed = m + 2
Yards of cloth used per dress = 5 yards
Cloth used altogether :
Cloths used for shirt = 2 * m = 2m
Cloth used for dress = 5 * (m+2) = 5m + 10
2m + (5m + 10) = 7m + 10
If m = 7
Cloth used for dress - Cloth used for shirt
(5(7) + 10) - (2(7))
(35+10) - 14
45 - 14 = 31 yards

What is the area of circle circumscribing a triangle?
An imaginary tangent line stretching from the triangle's two sides plus a section of the curve that is tangent to one side create this combination. The formula for the radius of a circle enclosing a triangle is
r = ABC / 4A.
Solution:
area of sector ABC = 85/360 × π × (7.3)² cm²
= 39.53 cm²
area of triangle ABC = 1/2 × 9 × 5.7 cm²
= 25.65 cm²
area of shaded region = area of sectot ABC ₋ area of triangle ABC
= 39.53 ₋ 25.65
= 13.88 cm²
Hence the area of shaded region is 13.88 cm²

What expression is equivalent to m(n+p)
Answer:
mn + mp
Step-by-step explanation:
m(n + p) =
m(n) + m(p) =
mn + mp
Hope that helps! :)
-Aphrodite
The equivalent expression for the algebra m(n+p) is mn + mp.
What are equivalent expressions?Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.
From the given information, we have:
= m(n + p)
To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:
= m(n) + m(p)
= mn + mp

Because when doing area for triangles its
base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16
so it would come out to 16 + 10 + 10 + 10 + 10 =

If you know that cosine of the obtuse supplementary angle -0.3456 what can you determine about the acute angle
Answer:
69.8°
Step-by-step explanation:
Since cosФ = -0.3456
Ф = cos⁻¹(-0.3456)
Ф = 110.2°
Since the angles are supplementary, let the acute angle be x
So, x + 110.2° = 180°
x = 180° - 110.2°
x = 69.8°
