Answer:
a) The maximum height that the ball reaches is 73.1 meter
b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds
Step-by-step explanation:
The complete question is
During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?
Solution:
For maximum height
[tex]\frac{dh}{dt} =0[/tex]
[tex]\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2[/tex]seconds
a) Maximum height
[tex]5 * t^2 + 22t + 0.5[/tex]
[tex]= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1[/tex]
b) Time elapsed when the ball reaches maximum height is 2.2 seconds
What is the value of the x ? x + x + x = 56
Hey there!
ORIGINAL EQUATION
x + x + x = 56
CONVERT/COMBINE the LIKE TERMS
1x + 1x + 1x = 56
2x + 1x = 56
NEW EQUATION
3x = 56
DIVIDE 3 to BOTH SIDES
3x/3 = 56/3
SIMPLIFY IT by canceling out 3/3 because it give you 1 & KEEP 56/3 because help solve for the x-value (it also give you the x-value result)
x = 56/3
x = 18.666667
x = 18 2/3
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE ALL EQUIVALENT TO EACH OTHER
Good luck on your assignment & enjoy your day!

Given the function g(x) = -3x + 4, compare and contrast g(-2) and g(4). Choose the statement that is true concerning these two values.
Answer: D
Step-by-step explanation:
Fill in the x's with -2 for the first time to get one answer then go back and fill in 4 for the second answer.
g(-2)= 10
g(4)=-8
Proving g(-2) is greater than g(4).

Find the geometric mean between 4 and 20.
Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Geometric mean is when you multiply the two numbers 4 and 20 and then take the square root of the product.
So 4 x 20 = 80, and the [tex]\sqrt{80}[/tex] = 4[tex]\sqrt{5}[/tex]
However-- that's if you meant finding the geometric mean of 4 and 20 when you said "between"
change 4x - 5y = 10 into slope intercept form and graph
Answer:
Slope intercept form: y = 4/5x - 2
Step-by-step explanation:
(subtract 4x from both sides) -5y = -4x + 10
(divide everything by -5) y = 4/5x - 2
To graph, place a point at (0,-2), and then travel up 4 and over right 5 (or down 4 and to the left 5) to place the next point, then draw a line through the points

Two streets form an intersection. C and D are supplementary
angles. If the measure of C is 140° and the measure of D is
two times the value of x, what is the value of x?
Answer:
20degrees
Step-by-step explanation:
The sum of angle C and D is 180 degrees since they are supplementary
Given
m<C = 140 degrees
m<D = 2x
Taking the sum and equating to 180
140 + 2x = 180
2x = 180-140
2x = 40
x = 40/2
x = 20 degrees
Hence the value of x is 20degrees

Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day
Answer:
26.3 grams
Step-by-step explanation:
57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)
Write an equation in point-slope form of the line that passes through the two given

The product of
two integers is – 24. The difference
between the two integers is 14. The sum of
the two integers is 10. What are the two
integers?
Answer:
a= 12
b=-2
Step-by-step explanation:
12 x -2 = -24
12 - (-2) = 14
12 + (-2) = 10
The two integers are 12 and -2.
What are simultaneous equation?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Let x and y be the two integers.
So it is given that,
Product of two integers = – 24
⇒ xy = - 24 ....(i)
The difference between the two integers = 14
⇒ x - y = 14 ...(ii)
The sum of the two integers = 10
⇒ x + y = 10 ....(iii)
Now adding equation (ii) and (iii) we get,
2x = 24
⇒ x = 12
Putting the value of x in equation (i) we get,
12y = - 24
⇒ y = - 2
So the required integers are 12 and - 2.

What’s the value of a?
Answer:
a = 69
Step-by-step explanation:
The linear pair equals 180 degrees.
a + 90 + 21 = 180
a + 111 = 180
a = 69
nice!
Answer:
A= 69 degrees
Step-by-step explanation:
if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.
21 + 90 = 111
180- 111 = 69
What is the value of angle 2?

66°
Please helpp
Answer:
The value of angle 2 is 114 degrees
Step-by-step explanation:
We start with 180 degrees, since it is a Line.
To fine the other degree, subtract 66 from 180, which is 114
Angle 2 is 114 because of the theory of interior alternate angles are congruent. Angle 1 is 66 degrees because of the same reason.

added to her bill. After, Emily added a 20% tip on the total after tax. What
was Emily's final total?
*
Answer: $22.68
Step-by-step explanation:
17.50 times 0.08 = 1.40
17.50 + 1.40 = 18.90
