A ball is thrown from the top row of seats in a stadium. The function h(t) = - 16t^2 + 80t + 96 gives the height, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
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

Jailene is mixing marshmallows and
Rice Krispies to make Rice Krispy
treats. The number of cups of
marshmallows, m, needed for r
cups of Rice Krispy r is described by
the equation r= 1.5m.
How many cups of marshmallows
are needed to mix with 3 cups of
Rice Krispies?
Answer:
m = 2
Step-by-step explanation:
The number of cups of marshmallows, m, needed for r cups of Rice Krispy r is described by the equation :
r= 1.5m ...(1)
We need to find the no. of marshmallows are needed to mix with 3 cups of Rice Krispies.
Pu r = 3 in equatin (1) :
[tex]m=\dfrac{r}{1.5}\\\\m=\dfrac{3}{1.5}\\\\m=2[/tex]
So, there are 2 cups of marshmallows .

m=16-12/4-3
m=4/1
m=4
Answer:
I think its m = 1/4
Step-by-step explanation:
subtract 4 from 3 and 16 from 12 and you will get the answer
Drag each tile to the correct box. A group of marine biologists on a marine expedition recorded the elevations at which they found a few animals, with respect to sea level. Arrange the animals in the decreasing order of the elevations at which the marine biologists found them. sea turtle -502 feet sea urchin -452 feet garden eel -396 feet great white shark -430 feet > > >
Answer:
Garden eel, Great white shark, sea urchin, Sea turtle
Step-by-step explanation:
Given that:
Animal ____ altitude
Sea turtle __ - 502
Sea urchin __ - 452
Garden eel __ - 396
Great white shark __ - 430
Arranging in decreasing order of elevation :
-396 > - 430 > - 452 > - 502
Hence, the animals can be arranged in decreasing order of elevation thus :
Garden eel, Great white shark, sea urchin, Sea turtle
Answer:
Garden eel, Great white shark, sea urchin, Sea turtle

The monthly gross receipts for the ABC Copy Creation house amounted to $20,834.34. Unfortunately the expenses amounted to $18,750.91, but this did give the owner of the company some profit. What was the profit for the month?
Answer:
the Profit for the month is $2,083.43
Step-by-step explanation:
The computation of the profit for the month is shown below:
Profit for the month is
= Monthly gross receipts - expenses
= $20,834.34 - $18,750.91
= $2,083.43
hence, the Profit for the month is $2,083.43
We simply applied the above formula so that the correct value could come
And, the same is to be considered

Domain: (-3, 1] and Range: [-4, 0]
Step-by-step explanation:
The domain is the set of the x-coordinates.
-3 is not included, but numbers greater than -3 are included up to 1, including 1.
Domain: (-3, 1]
The range is the set of the y-coordinates.
The lowest y-coordinate is -4, and the highest is 0.
Range: [-4, 0]
Answer: Domain: (-3, 1] and Range: [-4, 0]
Answer: Domain: {-3, oo) and Range: {0,oo)

What is the solution to 8(2^x+3)=48
16/3=48
Step-by-step explanation:
evaluate
happy holidays
The solution to the equation 8(2ˣ + 3) = 48 is x = 0.
Here, we have,
To solve the equation 8(2ˣ + 3) = 48, we can follow these steps:
Distribute the 8 to both terms inside the parentheses:
8 * 2ˣ + 8 * 3 = 48
Simplify the equation:
2⁽ˣ⁺³⁾ + 24 = 48
Subtract 24 from both sides to isolate the exponential term:
2⁽ˣ⁺³⁾ = 48 - 24
2⁽ˣ⁺³⁾ = 24
Rewrite 24 as a power of 2:
2⁽ˣ⁺³⁾ = 2³ * 3
Apply the property of exponentiation, where if two powers with the same base are equal, then their exponents must be equal:
x + 3 = 3
Solve for x by subtracting 3 from both sides:
x = 0
Therefore, the solution to the equation 8(2ˣ + 3) = 48 is x = 0.

Write the simplest polynomial function for each set of zeros
Zeros = -2, 5, -1
Answer:
the answer should be y = x^3 - 2x^2 - 13x - 10
Step-by-step explanation:
x = -2 5 -1
x + 2 = 0
x - 5 = 0
x + 1 = 0
f(x) = (x + 2) (x + 1)
x(x) + 2(x) + x(1) + 2(1)
x^2 + 2x + x + 2
x^2 + 3x + 2
f(x) = (x^2 + 3x + 2) ( x - 5)
x^2(x) + 3x(x) + 2(x) + x^2(- 5) + 3x(- 5) + 2(- 5)
x^3 + 3x^2 + 2x - 5x^2 - 15x - 10
x^3 - 2x^2 - 13x - 10
f(x) = x^3 - 2x^2 - 13x - 10

You can buy 5 pounds of grapes for $9.95. What is the cost c if you buy 4 pounds of grapes?
Answer:
$7.96
Step-by-step explanation:
The equation 9.95/5=x would give you the price of one pound of grapes.
So, now that you have x, you would find out how much it costs if you bought 4 pounds.
4*x=7.96
(x = 1.99)

Answer: NOT CONGRUENT
Step-by-step explanation:
Answer:
They are congruent because of ASA.
Step-by-step explanation:
Since these points are at the same rate, we can safely assume that it is congruent based on these given statements below. It is also ASA because angle B and angle C are mentioned in the given statements and there is a side explanation which is BC and EF which makes them angle-side-angle.
