Answer:
Area = 260
Step-by-step explanation:
The formula for the area of a 6-gon is
Area = 3*sqrt(3) * side^2 / 2
side = 10
Area = 3 * 1.7321 * 100/2
Area = 259.8
Area = 260
Which answer represents the domain of the logarithmic function given below? F(x) = log8x
a. x 0
b. x < 0
c. x > 0
d. All real number
ASAP !!!!
Answer:
C. [tex]x>0[/tex]
Step-by-step explanation:
Given: [tex]f(x)=log(8x)[/tex]
To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.
[tex]8x>0[/tex]
[tex]x>0[/tex]
So since x is greater than zero, we have just found out our domain:
Interval Notation: (0, ∞)
Set Notation: {[tex]x|x>0[/tex]}
The domain of the logarithmic function is,
⇒ x > 0
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that:
The function is,
⇒ F (x) = log₈ x
Now, To find the domain of a logarithmic function, we need to take the term, 8x, and set it greater to zero.
This is because an argument of a logarithmic function cannot be zero or negative.
Hence, We get;
8x > 0
x > 0
Thus, The domain of the logarithmic function is,
⇒ x > 0

slope intercept equation for (0,-4) and (4,1)
Answer:
y = (5/4)x - 4
Step-by-step explanation:
As we move from (0, -4) to (4, 1), x increases by 4 and y increases by 5.
Thus, the slope of the line segment connecting these two points is
m = rise / run = 5/4.
Subbing these knowns into the point-slope formula for the equation of a straight line, we get:
y - 1 = (5/4)(x - 4), or
y = (5/4)x - 5 + 1, or
y = (5/4)x - 4
Let's check this out. Determine whether or not (0, -4) satisfies the equation:
-4 = (5/4)(0) - 4
Yes, this is true; the equation is correct.

Simplify the expression given below x^2+x-2/x^3-x^2+2x-2
Answer:
The simplest form is [tex]\frac{x+2}{x^2+2}[/tex]
Explanation:
The given is: [tex]\frac{x^2 + x-2}{x^3-x^2+2x+2}[/tex]
1- For the numerator:
[tex]x^2+x-2[/tex] can be factorized to give (x-1)(x+2)
2- For the denominator:
[tex]x^3-x^2+2x-2[/tex]
We will factor this using grouping
Take [tex]x^2[/tex] as a common factor from the first two terms and [tex]2[/tex] as a common factor from the last two terms
This will give us:
[tex]x^3-x^2+2x-2[/tex] [tex]=x^2(x-1) + 2(x-1)[/tex]
Now, take (x-1) as a common factor:
[tex]x^3-x^2+2x-2[/tex] = (x-1)(x²+2)
3- Finally, getting the simplest form:
[tex]\frac{x^2+x-2}{x^3-x^2+2x-2}=\frac{(x-1)(x+2)}{(x-1)(x^2+2)}=\frac{x+2}{x^2+2}[/tex]
Hope this helps :)

Similar triangles are triangles which have the same shape but not the same size. This means their angle measures are equal but their side lengths are not instead they are proportional. To solve, we will set up a proportion and solve.
A proportion is two equal ratios set equal to each other. We form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). Out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:
[tex]\frac{BC}{EF} =\frac{AC}{DF}[/tex].
[tex]\frac{18}{x}=\frac{12}{10}[/tex]
To solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
[tex]\frac{18}{x}=\frac{12}{10}\\ 18*10 = x*12 \\ 180 = 12x \\ 15 = x[/tex]

How do you calculate the area of a circle. Area of a circle is equal to the times
Answer:
Radius Squared
Step-by-step explanation:
Following answer is Pi
The area of a circle is π times the square of its radius.
What is a circle?A circle is a locus of a point in a plane such that its distance from a fixed point always remains constant. This fixed point is called the centre of the circle while the distance between the centre and the moving point is called the radius of the circle.
The area of a circle is given by [tex]A=\pi r^{2}[/tex]
Where [tex]\pi[/tex] is an irrational number with a value of 3.14159...... and r is the radius of the circle.
So, the area of a circle is π times the square of its radius.
Hence, the area of a circle is π times the square of its radius.

How far will a freight train travel in 3 hours at an average speed of 48 miles per hour?
Answer:
48 X 3= 144 miles
Step-by-step explanation:
Answer:
144 miles
Step-by-step explanation:
First, let's use the distance formula which is distance = rate*time.
We know the rate is 48 miles and the time is 3 hours so if you were to plug it in to the formula you'd get distance = 48*3.
When you multiply 48 by 3 you get 144 which will be the distance.

Step-by-step explanation:
1 1/3x=-8/3
Answer:
x=−2 is the answer
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2/3(x - 4) = 2x
(2/3) (x) + (2/3) (-4) = 2x Distributed
2x/3 + -8/3 = 2x
Step 2: Subtract 2x from both sides.
2x/3 + -8/3 = 2x
(2x/3) (-2x/1) + -8/3 =0
-4x/3 + -8/3 = 0
Step 3: Add 8/3 to both sides.
-4x/3 = 8/3
Step 4: Multiply both sides by 3/(-4).
(3/-4) (-4x/3) = ( 3/-4) (8/3)
X= -2 because 3 x 8= 24 and -4 x 3 = -12

Complete the inequality statement. 14 ft ____ 4 1/2 yd.
ok if i am right their are 0.3333 yards in a foot so if their is 14 feet it would be 4.66667
so your answer would go to the 4 1/2
Answer:
14 ft > 4 1/2 yd.
Step-by-step explanation:
1 yard = 3 ft
so
4 1/2 yard = 4.5 x 3 = 13.5 ft so it's less then 14 ft or 14 ft is greater than 13.5 ft
answer
14 ft > 4 1/2 yd.

the price c of a used car plus 8% sales tax
Answer:
1.08c or c + 0.08c
Step-by-step explanation:
The price of any used car plus 8% tax can be found by writing an expression. You can write an expression using a variable c where c is the price of the car. You will pay the 100% the whole price of the car and add on 8% of the price as tax. This means you pay 100 + 8 = 108% of the price c. This is 1.08c. Or you can also write it as c + 0.08c.

The vertex form of the equation of
a parabola is y = 2(x +4^2 - 7.What is the standard form of the equation?
Answer:
The standard form of the equation is y = 2x^2 + 16x + 25
Step-by-step explanation:
To find the standard form, first square the parenthesis.
y = 2(x + 4)^2 - 7
y = 2(x^2 + -8x + 16) - 7
Now distribute the 2
y = 2(x^2 + 8x + 16) - 7
y = 2x^2 + 16x + 32 - 7
Now combine like terms
y = 2x^2 + 16x + 32 - 7
y = 2x^2 + 16x + 25
Answer:
y = 2x^2 + 16x + 25
Loren and Julie have different part-time jobs after school. They are both paid at a constant rate of dollars per hour. The tables bellow show Loren and Julie’s total income for work given amount of time.
How much money would Julie earn for working 16 hours?
Julie works 1/12 hours/dollars. Write one or two-sentence explanation of what this rate means use this rate to find how long it takes for Julie to earn $228
Julie would earn $12/h×16h=$192
This rate means that for each hour she works, she gets $12.
The general formula for calculating these types of problems is:
m = r × t,
where m marks the total amount of money, r marks the rate and t marks the time.
To find the time when
m = $228
r = $12/h,
t = m ÷ t = 228 ÷ 12 = 19 hours.
Julie's income for 16 hours is $192. Julie takes only 24 hours to earn $288. The rate is $12 for each hour.
What are ratio and proportion?A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given
Loren and Julie have different part-time jobs after school.
They are both paid at a constant rate of dollars per hour.
The income of Julie is $36 in 3 hours.
For 1 hour, Julie earns $12.
Thus the rate of Julie is $12 per hour.
For the 16 hours, Julie's income will be.
Julie's income for 16 hours = 12 x 16
Julie's income for 16 hours = $192
Julie's income for 16 hours is $192.
Julie takes time to earn $228 will be
[tex]\rm Time = \dfrac{288}{12}\\\\Time = 24[/tex]
Thus, Julie takes only 24 hours to earn $288.
