Manuel has scored 27,29 and 28 points in his three basketball games so far. How many points does he need to score in his next game so that his average (mean) is 28 points per game?
Answer:
28.71 points
Step-by-step explanation:
(27.29 + 28 + x) / 3 = 28
(27.29 + 28 + x) = 84
28 + x = 56.71
x = 28.71
The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28.
What is mean?The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.
Mean = sum of data / Number of data
As per the given,
Manuel has scored 27,29 and 28 points in his three basketball games so far.
Suppose his score in the fourth game is x.
Mean = (27 + 29 + 28 + x)/4 = 28
(84 + x)/4 = 28
84 + x = 112
x = 28
Hence "The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28".

Jesse has a storage container in the shape of a right rectangular prism. The volume of the container is 43.875 cubic meters, the length is 5 meters and the width is 3.9 meters.
Note: Consider we need to find the height of the container.
Given:
The volume of container in the shape of right rectangular prism = 43.875 cubic meters.
Length = 5 meters.
Width = 3.9 meters.
To find:
The height of the container.
Solution:
We know that the volume of a rectangular prism is:
[tex]V=l\times w\times h[/tex]
Where, l is length, w is width and h is height.
Putting [tex]V=43.875,l=5,w=3.9[/tex] in the above formula, we get
[tex]43.875=5\times 3.9\times h[/tex]
[tex]43.875=19.5\times h[/tex]
[tex]\dfrac{43.875}{19.5}=h[/tex]
[tex]2.25=h[/tex]
Therefore, the height of the rectangular container is 2.25 meters.

Solve The Quadratic Equation by the Square Root Method.
(x + 2)^2=25
Answer:
x=-7, x=3
Step-by-step explanation:
Seperate into possible cases
Solve the equation
Answer:
x = 3 or x = -7
Step-by-step explanation:
(x + 2)^2=25
Take the square root of each side
sqrt((x + 2)^2)=sqrt(25)
x+2 = ± 5
Subtract 2 from each side
x+2-2 = -2 ±5
x = -2 +5 or x = -2 -5
x = 3 or x = -7

2) What x value makes the exponential function greater than the
quadratic function?
A)X = -2
B)x = 0
X = 2
D) =4
Answer:
The answer is b
Step-by-step explanation:
X= 0 makes the exponential function greater than the quadratic function. Therefore, the correct option is option B.
What is exponential function?The mathematical symbol for the exponent is [tex]e^{X}[/tex]. The word, unless specifically stated differently, generally relates to the positive-valued functional of something like a real variable, though it can be extended towards the complex numbers or adapted to other mathematical like matrices or Lie algebras.
The idea of exponentiation is where the exponential function got its start, although recent definitions allow for a rigorous extension to all real arguments, especially irrational values. X= 0 makes the exponential function greater than the quadratic function.
Therefore, the correct option is option B.

Area is l*w and since the length is known, solve for width
182/13=13w/13
w=14
Answer:
14 units
Step-by-step explanation:
Given, the area of rectangle = 182 square units
length = 13 units
width = ?
By using the formula to find the area of a rectangle, we have
area of rectangle = length * width
182 = 13 * width
182/13 = width
14 units = width
For which function k does the output increase by 20% every time the input increases by 1?
Answer:
k(x) = 1.20^x
Step-by-step explanation:
Here, we want to get a function
The output in this case refers to k(x)
the input refers to the value x
So, for every 1 increase in x, we want k(x) to increase by 20%
20% is same as 20/100 = 0.2
So at an initial value of 1, each increase if 20% will be 0.2 + 1 = 1.2
So therefore, we have the function as;
k(x) = 1.20^x
