A ball is thrown into the air. Its height in
feet after t seconds is given by the
function h(t) = −5t² + 20t. How high will
the ball be after 3 seconds?
Answers
Answer:
15 ft
Step-by-step explanation:
h(t) = −5t² + 20t (Given)We need to find: height of the ball after 3 seconds.So, plug t = 3 in the above equation, we find:h(3) = −5(3)² + 20(3)->h(3) = −5(3)² + 20(3)->h(3) = −5(9) + 60->h(3) = −45 + 60->h(3) = 15 feetRelated Questions

Answer: Discriminant, in mathematics, a parameter of an object or system calculated as an aid to its classification or solution. In the case of a quadratic equation ax2 + bx + c = 0, the discriminant is b2 − 4ac; for a cubic equation x3 + ax2 + bx + c = 0, the discriminant is a2b2 + 18abc − 4b3 − 4a3c − 27c2

Answer:
Option C √32 is correct
Step-by-step explanation:
Here,
x₁ = 8
x₂ = 4
y₁ = (-3)
y₂ = (-7)
Now,
By Using Distance Formula
D = √(x₂ - x₁)² + (y₂ - y₁)²
= √(4 - 8)² + [(-7) - (-3)]²
= √(-4)² + [(-7) + 3]²
= √16 + (-4)²
= √16 + 16
D = √32
Thus, The distance between (8, -3) and (4, -7) is √32

Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?
Answer:
Minutes = 8 minutes
Step-by-step explanation:
Topic: Inequality
Given:
Available Size of water = 17 liters
Increment = 5 liters/minute
Size of water needed = At least 57 liters
Putting the above together, as have
17 + 5m > 57
where m represents total minutes and > represent at least
Solving the Inequality
5m > 57 - 17
5m > 40 ------ Divide through by 5
5m/5 > 40/5
m > 8
So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.

Remark
His pay gets income tax deducted at a rate of 18% = 18/100
That means you multiply is weekly wage by 18/100 to get what the government takes off.
Solution
18/100 * 495 = 80.10
The government takes $80.10
His take home pay is 495 - 80.10 = $405.90
Note:
There is a short way of doing his take home pay if that is all you are interested in. His take home pay is 82% of his gross pay which is 82/100 * 495.
82/100 * 495 = 405.90

15 tractors each working 8 hours a day take to take eight days to Plough a piece of land how many days will it take 24 tractors each working 10 hours a day to plough the same piece of land
Answers
It will take 24 tractors, each working 10 hours a day, a total of 4 days to plough the same piece of land.
To determine how many days it will take 24 tractors, each working 10 hours a day, to plough the same piece of land, we can use the concept of man-hours.
Given that 15 tractors, each working 8 hours a day, took 8 days to complete the task, we can calculate the total man-hours required to plough the land.
Total man-hours = Number of tractors * Hours per tractor * Number of days
Total man-hours = 15 tractors * 8 hours/tractor * 8 days
Total man-hours = 960
Now, let's calculate the number of days required for 24 tractors, each working 10 hours a day, to complete the task.
Number of days = Total man-hours / (Number of tractors * Hours per tractor)
Number of days = 960 / (24 tractors * 10 hours/tractor)
Number of days = 960 / (240)
Number of days = 4
As a result, ploughing the same plot of land will require 24 tractors to labour for a total of 4 days at 10 hours per day each.
