The graph is a line.
The graph intersects
the x-axis.
The input x-1 has
many outputs.
The graph is a
vertical line.
Answer:
The input x = 1 has many outputs.
The graph is a vertical line.
Step-by-step explanation:
Hi there!
A function is defined as a relation that only gives one output for every given input. For every x-value, there is only one y-value.
Because the x-value of 1 gives us an infinite number of y-values, this is therefore not a function.
More generally, no vertical line is a function for this reason.

Answer:
See answer below
Step-by-step explanation:
[tex]V = \frac{4}{3} \pi r^3[/tex] 2km = radius
[tex]V=\frac{4}{3}\pi (2)^3[/tex]
[tex]V = \frac{4}{3}\pi (8)[/tex]
[tex]V = \frac{4}{3}(8)\pi[/tex]
[tex]V =\frac{32}{3}\pi[/tex] [tex]\pi =3.14[/tex]
[tex]V = \frac{32}{3}(3.14)[/tex]
[tex]V = 33.493[/tex]
V≈ 33.49
Using π on the calculator
[tex]V = \frac{32}{3} \pi[/tex]
[tex]V = 33.510[/tex]
V ≈ 33.51

Find the measures of each numbered angles
Answer:
∠ 1 = 109° , ∠ 2 = 29° , ∠ 3 = 71°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 35° + 36° = 180°
∠ 1 + 71° = 180° ( subtract 71° from both sides )
∠ 1 = 109°
-------------------
∠ RVU and ∠ 1 are adjacent angles on a straight line and sum to 180° , then
∠ RVU + ∠ 1 = 180°
∠ RVU + 109° = 180° ( subtract 109° from both sides )
∠ RVU = 71°
In Δ RVU
∠ 2 + 80° + 71° = 180° ( sum of angles in triangle )
∠ 2 + 151° = 180° ( subtract 151° from both sides )
∠ 2 = 29°
-------------------------
∠ 3 and ∠ RVU are vertically opposite angles and are congruent , then
∠ 3 = 71°
Δ UVT has: ∠V₁ = 180⁰ - ∠TUV - ∠VTU = 180⁰ - 35⁰ - 36⁰ = 109⁰
We have: ∠RVU = ∠V₃ = 180⁰ - ∠V₁ = 180⁰ - 109⁰ = 71⁰
ΔRVU has: ∠U₂ = 180⁰ - ∠URV - ∠ RVU = 180⁰ - 80⁰ - 71⁰ = 29⁰
Answer:
∠V₁ = 109⁰∠U₂ = 29⁰∠V₃ = 71⁰Ok done. Thank to me :>
The sum of the measures of three adjacent angles is 150∘. The measures of the angles are in the ratio of 1:2:3. What is the measure, in degrees, of the largest angle?
Answer:
75°
Step-by-step explanation:
1:2:3
so there are a total of 6 parts. Then, each part would be:
=) 150÷6= 25
The largest angle is 3 parts. so, if 1 part is 25, 3 parts is 25×3= 75
The largest angle is is 75°

Nora rings up an item that costs $86.25. After sales tax, the total is $91.08. What is the sales tax percentage?
Write your answer as a decimal using a percent sign (%). For example, 0.5% or 12.7%
Answer:
The sales tax is equal to 5.6%
Step-by-step explanation:
To solve first we have to subtract the item's cost before sales tax from the total due. 91.08 - 86.25 = 4.83.
Next we take the amount we payed as tax and divide it by the pre-tax price. 4.83/86.25 = 0.056
Lastly we take 0.056 and convert it to a percentage. This can be accomplished by moving the decimal sign to 2 times to the left or multiplying the tax rate by 100.
The sales tax percentage is equal to 5.6%

In right triangle ABC below, CD is the altitude to hypotenuse AB. If CD=6 and the ratio of AD to AB is 1:5, determine and state the length of BD.
Step-by-step explanation:
the altitude makes a right angle at hypotenuse
cd^2+ ad^2 = ac^2
36+ (h/5)^2 = ac^2
ad/ab = 1/5; ad/h = 1/5; ad=h/5
similarly
bd^2+cd^2 = bc^2
(4/5)^2+ 36 = bc^2
ac^2+bc^2 = ab^2
36+h^2/25+ 16/25h^2+36 = h^2
h= 15
bd/ab = 4/5
bd= .8*15=12

Scores on an exam follow an approximately normal distribution with a mean of 76. 4 and a standard deviation of 6. 1 points. What percent of students scored above 75 points?.
Using the normal distribution, it is found that 59.09% of students scored above 75 points.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is [tex]\mu = 76.4[/tex].The standard deviation is [tex]\sigma = 6.1[/tex].The proportion of students who scored above 75 points is 1 subtracted by the p-value of Z when X = 75, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{75 - 76.4}{6.1}[/tex]
[tex]Z = -0.23[/tex]
[tex]Z = -0.23[/tex] has a p-value of 0.4091.
1 - 0.4091 = 0.5909
0.5909 = 59.09% of students scored above 75 points.

Answer:
15 cm²
Step-by-step explanation:
To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².
In equation form would be:
V=A×L [V=volume A=area L=length]
So if you do inverse operations you would divide the volume by the length to get the area.
V/L=A
You rent an apartment that costs $1200 per month during the first year, but
the rent is set to go up $90 per year. What would be the monthly rent during
the 6th year of living in the apartment?
Answer:
In year 6 monthly rent would cost you $1650 and it would cost $19,800 for the whole year of year 6
Step-by-step explanation:
1200x12=14,400 = year 1
1290x12=15,480=year 2
1380x12=16,560=year 3
1470x12=17,640=year 4
1560x12=18,720=year 5
1650x12=19,800=year 6
The monthly rent during the 6th year of apartment is A = $ 1,650
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
After each year, the rent goes up by $90, so in the second year the rent would be $1200 + $90 = $1290 per month, in the third year it would be $1290 + $90 = $1380 per month, and so on
On simplifying the equation , we get
Therefore, during the 6th year of living in the apartment, the monthly rent would be:
A = $1200 + ($90 x 5)
A = $1200 + $450
A = $ 1,650
Hence , the monthly rent is A = $ 1,650
