Factor this polynomial completely x2-8x+16
Answers
Answer:
X^2-8x+16
X^2-4x-4x+16
Factorise by gouping terms
X(x-4)-4(x-4)
=(x-4)(x-4)
There are a couple of formulas that we should know about quadratic functions, and this one utilizes this one:
(x - a)^2 = x^2 -2ax + a^2
Notice how x^2 - 8x + 16 fits into the formula:
x^2 - 8x + 16
x^2 - 2*x*4 + 4^2
(x - 4)^2
(x - 4)(x - 4)
Of course, not all expanded quadratic expressions fit into that formula, so there is a universal method to factor quadratic expressions:
x^2 + x(a + b) + ab —> (x + a)(x + b)
Basically, the middle term is the sum of an and b times x, and the last term is the product of an and b. So, if we are using the expression given in the problem, notice how -4 * -4 is 16, and the sum of -4 and -4 is -8. Thus, a and b are both -4 and the factored form is (x - 4)(x - 4)
You and a friend want to know how much rope you need to climb a large rock. Your friend is 5.5 feet tall and casts a shadow that is 18 feet long. If the rock casts a shadow that is 209.5 feet long, calculate the height of the rock from the ground. Round your answer to the nearest foot. (Hint: make a drawing) a. 64 ft b. 18 ft c. 210 ft d. 219 ft
Answers
Answer: The value of x from the equation is 64 ft. Thus, they will be needing approximately 64 ft of rope.
Step-by-step explanation: The concept that is useful in order to answer this item is the concept of ratio and proportion. Let x be the height of the rock from the ground. We use the equation below to answer.
5.5 ft / 18 ft = x ft / 209.5 ft

From a random sample of 16 people in a jail, the number of days remaining in each their sentences was noted. The 16 people have a mean remaining sentence of 645 days with a standard deviation of 31 days. Assume the population of remaining sentences is normally distributed. Construct a 95% confidence interval for the mean remaining sentence of all people in the jail. Round final answer to one decimal place.
Answers
Answer:
The 95% confidence interval for the mean remaining sentence of all people in the jail is between 628.5 days and 661.5 days.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 16 - 1 = 15
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 15 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.1315
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.1315\frac{31}{\sqrt{16}} = 16.5[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 645 - 16.5 = 628.5 days
The upper end of the interval is the sample mean added to M. So it is 645 + 16.5 = 661.5 days
The 95% confidence interval for the mean remaining sentence of all people in the jail is between 628.5 days and 661.5 days.

Solution:
We have,
[tex]x=\log_{10}31,500[/tex]
It can be written as
[tex]x=\log_{10}(2^23^25^37)[/tex]
[tex]x=\log_{10}(2^2)+\log_{10}(3^2)+\log_{10}(5^3)+\log_{10}(7)[/tex] [tex][\because \log(ab)=\log a+\log b][/tex]
[tex]x=2\log_{10}2+2\log_{10}3+3\log_{10}5+\log_{10}(7)[/tex]
[tex]x=2\left(0.30105\right)+2\left(0.47712\right)+3\left(0.69897\right)+0.8451[/tex]
[tex]x=4.49835[/tex]
Clearly, the value of x lies between 4 and 5. So, [tex]x>4[/tex] and [tex]x<5[/tex].
Therefore, the correct options are C and D.
The true statements are: (c) x > 4 and (d). x < 5
The logarithmic expression is given as:

[tex]x = \log_{10}(315) + \log_{10}(100)[/tex]
Evaluate log 100 base 10
[tex]x = \log_{10}(315) + 2[/tex]
Evaluate log 315 base 10
[tex]x = 2.50 + 2[/tex]
Add the expressions
[tex]x \approx 4.50[/tex]
4.5 is greater than 4 and less than 5

The Holbrooks ordered 25 gallons of orange juice and 16 pints of cranberry juice for their resturant. How much juice do they have in all?
Answers = a- 57 gallons b- 29 gallons
c- 216 gallons d- 164 gallons
Answers
Answer:
27gallons
Step-by-step explanation:
First we need to convert 16pints to gallons
Since;
1 pint = 0.125gallons
16 pints = x
Cross multiply
1 * x = 16 * 0.125
x = 2gallons
Since Holbrooks ordered 25 gallons of orange juice and 16 pints of cranberry juice for their resturant, the total juice he has is 25gallons + 2 gallons = 27gallons

The area of the school is about 827 m² less than the area of the museum.
What is area?Area is the amount of area occupied by an object's flat (2-D) surface or shape.
Given:
Sammy finds satellite images of a school and a museum. They put the images on a coordinate grid (shown below).
School coordinate values are in meters.
To find the area of the school:
The school is rectangular.
Area of the rectangle = length x width
To find the length,
use distance formula.
We interpreted coordinates,
Fort length (-20, 20) and (-40, 80)
For width (-50, 10) and (80, -20)
Distance of length = √(60)²+(-20)² = 20√10
Distance of width = √(30)²+(10)² = 10√10
Area of the rectangle = length x width
Area of the rectangle = 20√10 x 10√10 = 2000 m²
The area of the museum is πr².
And r = 30
The area of the museum = π(30)². ≈ 2827 m².
Subtracting the area's = 827 m².
Therefore, the area of the school is about 827 m² less than the area of the museum.

There are 175 cubic unit initially in the tank
How to determine the initial amount of water?The table of values is given as:
Time (minutes) Amount of Water
1 150
3 100
6 25
Calculate the slope (m) of the table using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (100 - 150)/(3 -1)
Evaluate
m = -25
This means that as the time increases by 1, the amount of the water reduces by 25 cubic unit
When x = 1, y = 150
So, we have:
x = 1 - 1 when y = 150 - (-25)
This gives
x = 0 when y = 175
Hence, there are 175 cubic unit initially in the tank

Kristen owns a bakery and is making a cake for a wedding. The dimensions of the cake are shown below. Answer each of the questions below.
What is the frosted area of the top cake? (Round to the nearest tenth)
What is the frosted area of the bottom cake? (Round to the nearest tenth)
What is the total surface area of cake that will be frosted?
Answers
Answer:
$22.5.
Step-by-step explanation:
The total revenue that is gained from the sales of the cakes is determined by multiplying the number of cakes by the price. If we let x be the number of $1 that should be deducted from the price and y be the total revenue,
y = (25 - x)(100 + 5x)
Simplifying,
y = 2500 + 25x - 5x²
We get the value of x that will give us the maximum revenue by differentiating the equation and equating the differential to zero.
dy/dx = 0 = 25 - 10x

Step-by-step explanation:
my explanation is in the picture
The value of w and x in circle M below mathematically given as
w = 74 , x = 32
What is the value of w and x in circle M below?
Generally, the equation for the sum of angle of a triangle is mathematically given as
w+x+c = 180
w+a = 106
w+x = 106
therefore,
106 +c = 180
c = 180-106
c = 74
w = 74
thus,
w+x+c = 180
74 + x + 74 = 180
x = 180 -148
x = 32
In conclusion, the value of w and x in circle M below is
w = 74 , x = 32
