Answer:
2s or 3s
Step-by-step explanation:
Given the function that models the height of the object as;
h(t) = - 16t^2 + 80t + 96
The ball reaches the ground when h = 0
Substitute
0 = - 16t^2 + 80t + 96
Divide through by -16
0 = t²-5t-6
t²-5t-6 = 0
t²-2t-3t+6 = 0
t(t-2)-3(t-2) = 0
(tt-2)(t-3) = 0
t - 2 = 0 and t-3 = 0
t = 2 and 3s
Hence it will take the ball 2s or 3s to reach the ground
Subtract the expressions: (5z + 4) - 5(-3z -6)
Hey there!
“(5z – 4) – 5(–3z – 6)”
DISTRIBUTE the RIGHT side of your equation
5z – 4 –5(–3z) + (–5)(–6)
–5(–3) = 15z
(–5)(–6) = 30
NEW EQUATION: 5z – 4 + 15z + 30
COMBINE your LIKE TERMS
(5z + 15z) + (4 + 30)
5z + 15z = 20z
4 + 30 = 34
ANSWER: 20z + 34 ☑️

Find the value of x so that the function has the given value.
n(x) = -6x + 2; n(x) = 44
9514 1404 393
Answer:
x = -7
Step-by-step explanation:
Substitute the given value and solve for x
n(x) = -6x +2
44 = -6x + 2
42 = -6x . . . . . subtract 2
-7 = x . . . . . . . divide by -7
n(x) will have the value 44 for x = -7.

An angle measures 29.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
104.6 deg, 75.4 deg
Step-by-step explanation:
One angle measures x.
The other angle measures 29.2 deg less than x, so it measures x - 29.2.
They are supplementary angles, so the sum of their measures is 180 deg.
x + x - 29.2 = 180
2x - 29.2 = 180
2x = 209.2
x = 104.6
x - 29.2 = 75.4
Answer: 104.6 deg, 75.4 deg

Answer:
Frequency = 8 Hz ; Period = 0.125 s
Step-by-step explanation:
The amplitude of a wave is simply regarded as the maximum displacement experienced by a vibrating both from its equlibrum position.
The Displacement marked A in th picture is tbe Amplitude of the wave
The wavelength refers to the a complete cycle moved by a wave, that is the distance from a crest to another (maximum upward Displacement) or a trough to another (maximum downward Displacement).
2.)
Given that :
Velocity (V) of wave = 20 m/s
Wavelength (λ) = 2.5 m
The frequency (f) of the wave ;
f = v /λ
f = (20 m/s) ÷ 2.5m
f = 8 Hz
The period T of the wave :
T = 1 /f
T = 1 / 8
T = 0.125 seconds

Grandma gave 13 pieces of jewelry and grandma fien gave y pieces to the sister to divide evenly among them selves.There are 5 sister
Complete question :
Grandma gave 13 pieces of jewelry and grandma fien gave y pieces to the sister to divide evenly among them selves.There are 5 sister. How many pieces of jewelry does each sister get
Answer:
(13 + y) / 5
Step-by-step explanation:
Given that :
Number of jewelries Given by grandma = 13
Number of jewelries Given by grandma fien = y
Total number of jeweleries Given = (13 + y)
Number of people among which the jeweleries is to be divided = 5
Hence, since the distribution is to be even, then, each sister gets :
Total jeweleries / number of sisters
(13 + y) / 5

frankie can build a speaker box in 120 minutes trash can build a speaker box 40 minutes faster if they work together how many minutes does it take them to build the speaker box
9514 1404 393
Answer:
48 minutes
Step-by-step explanation:
Each minute, F can build 1/120 of a speaker box, and T can build 1/80 of a speaker box. Working together, in 1 minute, they can complete ...
1/120 + 1/80 . . . . . speaker boxes
= 2/240 +3/240 = 5/240 = 1/48 . . . . speaker boxes
Then there will be 1 complete speaker box after 48 minutes.

A firm has a cash conversion cycle of 80 days, an average collection period of 25 days, and an average age of inventory of 70 days. Its operating cycle is ________ days.
Answer: 95 days
Step-by-step explanation:
Cash conversion cycle = 80 days
Average collection period = 25 days
Average age of inventory = 70 days
Then, operating cycle will be:
= Average collection period + Average age of inventory
= 25 days + 70 days
= 95 days

You want to buy a shirt that costs $14. Identify an inequality that represents the amount of money, x (in dollars), you will have left if you buy the shirt
Complete question :
You can spend up to $35 on a shopping trip.
a. You want to buy a shirt that costs $14. Write and solve an inequality that represents the amount of money you will have left if you buy the shirt.
b. You notice that the shirt is on sale for %30 off. How does this change the inequality?
c. Do you have enough money to buy the shirt that is on sale and a pair of pants that cost $23? Explain.
Answer:
x ≤ 21
x ≤ 25.2
Yes
Step-by-step explanation:
Cost of shirt = $14
Total Amount to spend ≤ $35
After shirt purchase :
Let amount left = x
x + 14 ≤ 35
x ≤ 35 - 14
x ≤ $21
B.) discount on shirt sale = 30%
(100% - 30%) of $14 = 0.7 * $14 = $9.8
x ≤ 35 - 9.8
x ≤ 25.2
C.)
Cost of Jean = 23
25.2 > 23
Hence, there is enough money

Step-by-step explanation:
(3 , -4) ; slope(m) = 2/3
y - y1 = m (x -x1)
[tex]y - [-4] = \frac{2}{3}(x - 3)\\\\y + 4 = \frac{2}{3}x - 3*\frac{2}{3}\\\\y +4 = \frac{2}{3}x-2\\\\ y = \frac{2}{3}x - 2 - 4\\\\ y = \frac{2}{3}x - 6[/tex]

Marion is 24, Judy is 12
Step-by-step explanation:
Let j represent Judy's age now. 6 year ago, the relation was ...
3(j -6) = (2j) -6
3j -18 = 2j -6 . . . . . eliminate parentheses
j = 12 . . . . . . . . . . . add 18-2j
2j = 24 . . . . . . . . . Marion's age now
Judy is 12; Marion is 24.
