Step-by-step explanation:
A ball is thrown directly upward from a height of 3 ft with an initial velocity of 20 ft/sec. The function s(t)=-16t^2+20t+3 gives the height of the ball, in feet, t seconds after it has been thrown. Determine the time at which the ball reaches its maximum height and find the maximum height.
Answer:
#1: s'(t)= -32t+20
#2: -32t+20=0
t=2/3
#3: s(2/3)=-16(2/3)^2+20(2/3)+3=83/9
Step-by-step explanation:
first find the derivative of the original funtion #1
set the equation equal to 0 because when s't=0 is the maximum height
put the t at highest point into the funtion to solve for distance

The measure of angle JKL can be represented using the expression 3x + 5.
Answer:
The measure of ∠JKL is 65°
Step-by-step explanation:
Consider the provided diagram.
We need to find the degree measure of ∠JKL.
It is given that ∠JKM=45° and ∠MKL=x°
Also it is given that the measure of angle JKL can be represented using the expression 3x + 5.
Thus ∠JKL=3x+5
From the figure it can be concluded that ∠JKL is equal to the sum of ∠JKM and ∠MKL
This can be written as:
∠JKL = ∠JKM+∠MKL
Substitute the respective values in the above equation.
3x+5 = 45+x
Subtract x and 5 from both the sides.
3x+5-x-5 = 45+x-x-5
2x = 40
x = 20
Thus, the measure of ∠MKL=20°
Substitute the value of x in ∠JKL = 3x+5.
∠JKL = 3(20)+5
∠JKL = 60+5
∠JKL = 65
Hence, the measure of ∠JKL is 65°

Answer:
To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

Joy makes 6.5 litres of soup, correct to the nearest 0.5 litres.
She serves the soup in 280ml portions, correct to the nearest 10ml.
22 people order this soup.
Does joy definitely have enough soup to serve 22 people?
Show how you decide.
Your final line must be written as,Joy definitely does have enough soup or Joy may not have enough soup.
I tried so hard to answer it but it isn't right so if you give me an answer please explain it so next time I will have a similar type of question I will know how to do it.
This is what i tried
6250:275=22.8 (1 d.p)
Answer:
She can serve up to 22 people
Step-by-step explanation:
Given that the total amount of soup that Joy makes in liters is 6.5L
also that the portions are in ml
280ml to liters we have 280/1000= 0.28L
our aim is to know weather 6.5L divided by 0.28L can be up to 22
let us try it out
6.5/0.28= 23.214
we have 23.
Therefore the 6.5L can serve up to 22 portions of 280ml in 6.5 L of soup
Find the slope of the line that passes through:
(-4,7) and (-6, -4)
Answer:
[tex]\frac{11}{2}[/tex] or 5.5
Step-by-step explanation:
In order to find the slope of a line using two points on a graph, you must use
[tex]y_2-y_1/x_2-x_1[/tex]
Pluging in the points (-4,7) and (-6, -4) to the formula you will get:
[tex]\frac{-4-7}{-6+4} =\frac{-11}{-2} =5.5[/tex]
The equation for the line would be [tex]\frac{11}{2}[/tex]x+29

z1 =3+4i and z2=4+3i then what is the relation of z1 and z2?
The modulus of the functions z₁ and z₂ will be same.
What is Modulus function?
The modulus function is the absolute value of a positive or negative number.
Given that;
The functions are,
⇒ z₁ = 3 + 4i
⇒ z₂ = 4 + 3i
Now,
Since, The functions are,
⇒ z₁ = 3 + 4i
⇒ z₂ = 4 + 3i
Hence, The modulus of the functions are find as;
⇒ | z₁ | = √ 3² + 4²
⇒ | z₁ | = √ 9 + 16
⇒ | z₁ | = √ 25
⇒ | z₁ | = 5
And, | z₂ | = 4 + 3i
⇒ | z₂ | = √ 4² + 3²
⇒ | z₂ | = √ 16 + 9
⇒ | z₂ | = √ 25
⇒ | z₂ | = 5
Thus, The modulus of the functions z₁ and z₂ will be same.

After a bad break up, you decide to burn all the things a former boyfriend/girlfriend has given to you and any keepsakes. You have 50 items to put into the "pit" to burn. There are 85% of the items remaining at the end of 5 minutes. When will all your memories be gone?
Answer:
5.9 minutes
Step-by-step explanation:
85% of 50 items is gone in 5 minutes
42.5 items = 5 minutes
50 items = x minutes
42.5 items × x minutes = 50 items × 5 minutes
x = 50 items × 5 minutes/42.5 items
x = 5.8823529412 minutes
x ≈Approximately to 1 decimal place 5.9 minutes

3. Marcus was offered a position which pays a salary of $150 every week and a 25 cent commission for each ice cream cone he sell. Marcus sells an average of 125 ice cream cones each week. How much will Marcus make in the new position. Compare this to how much he made for a week at his current job. She he take the new position? Why or why not?
Answer:
Should he take the new position?
He shouldn't not take the new position
Why or why not?
This is because he makes a lot more at his old job than his new position
Step-by-step explanation:
Please find attached to this answer, Marcus worksheet at for a week at the coffee shop
For his first job
Marcus works at a coffee shop. He earns $10.25 each hour.
Let the number of hour is = x
The equation is given as:
$10.25x
For a week
October 11, He worked from 5:45 - 12.00pm = 6 hours 15 mins = $61.5
For his
October 12, He worked from 5:45 - 1:00pm = 7 hours 15 mins = 71.75
October. 13
3. Marcus was offered a position which pays a salary of $150 every week and a 25 cent commission for each ice cream cone he sell.
Let the number of ice cream sells be equal to x
25cent = $0.25
$150 + $0.25× x
$150 + $0.25x
Marcus sells an average of 125 ice cream cones each week.
The amount Marcus makes in his new position in 1 week =
$150 + $0.25 × 125
= $150 + $31.25
= $181.25
Compare this to how much he made for a week at his current job.
Marcy makes more at his old job than his new position.
Should he take the new position?
He shouldn't not take the new position
Why or why not?
This is because he makes a lot more at his old job than his new position

A class is playing a game called “Guess my Number,” in which the number is an integer. The teacher gives these clues for the unknown number.
4 + h ≤ 7 and h + 1 > 3
What is the value of the unknown number, h?
Answer:
h=3
Step-by-step explanation:
you want h alone on one side of the equation and you must do the same to both sides, 4-4 cancels out the 4, 7-4=3 so h is greater than or equal to 3, next, 1-1 cancels out 1, 3-1=2 so h>2, therefore h=3
Answer:
h = 3

Answer:
5/2 or 2.5
Step-by-step explanation:
use the equation y=mx+c
where m=slope=coefficient of x
-5x+2y=10
