I don’t understand how this works?
Please help, thanks.
Answer:
(B) Is the answer here
Step-by-step explanation:
Well a function’s domain can’t repeat no matter what.
Domain is X.
So the first one doesnt work since it repeats to every single digit that exists.
The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.
Answer:
B
Step-by-step explanation:
Hello There!
In order for the relations to be a function the x values may not repeat
For answer choice A the x value -2 repeats multiply times therefore the relation is not a function
For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices
For answer choice C the x values -3 and 2 repeat therefore it is not a function
For answer choice D the x value 2 repeats therefore the relation is not a function
So we can conclude that the correct answer is B

Answer: The answer to what is the measure of angle x is 48°.
Step-by-step explanation: It’s because this angle is complementary Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Example: 5° and 85° are complementary angles.
48°+42°=90° and this is a right scalene triangle.

plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 132 t + 108 h ( t ) = - 16 t 2 + 132 t + 108 models the ball's height above the ground, h ( t ) h ( t ) , in feet, t t seconds after it was thrown. a) What is the maximum height of the ball?
Answer:
The maximum height of the ball is 380.25 feet in the air.
Step-by-step explanation:
The quadratic function:
[tex]h(t)=-16t^2+132t+108[/tex]
Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.
We want to determine the maximum height of the ball.
Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.
Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:
[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]
In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:
[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]
So, the maximum height occurs after 4.125 seconds of the ball being thrown.
To find the maximum height, substitute this value back into the equation. Thus:
[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]
The maximum height of the ball is 380.25 feet in the air.
"What is the GCF (greatest common factor) of 60x^3- 10x^2+ 30x?
Answer:
10x
Step-by-step explanation:
Given the expression 60x^3- 10x^2+ 30x, we are to find the GCF
First let us find the factors of each terms
60x³ = 6 * (10 * x) * x²
10x² = 1 * (10 * x) * x
30x = 3 * (10 * x)
From the three factors, you can see that 10*x is common to them all. Hence the GCF of the expression will be 10x

A trapezoid has bases of 20 inches and 30 inches. The height of the trapezoid is 15 inches. What is the area of the trapezoid in square inches? in2
Answer:
375in^2
Step-by-step explanation:
area of a trapezoid is base + base divded by 2 then times that by the height
20 + 30 = 50
50/2 + 25
25 x 15 = 375

Calculate
√6x√20 divided by
√3
Give your answer in the form a√b where a and b are integers, and b is as small as
possible.
Answer:
(√6x√20) / √3 = 2√10
Step-by-step explanation:
hello :
(√6x√20) / √3 =√2x√3 x√4x√5 / √3
because : √6 = √2x√3 and √20= √4x√5 = 2x√5
now simplify by √3 :(√6x√20) / √3 =√2x2x√5
(√6x√20) / √3 = 2√10 so : a =2 and b =10
The number of households without a computer at home in 2009 was closest to A)801000 B)1153000 C)1737000 D)3433000 E)4017000
Answer:
B) 1153000
Step-by-step explanation:
Given
See attachment
Required
Number of households without computer in 2009
From the attachment, we have:
[tex]n=5170000[/tex] --- survey
[tex]p = 22.3\%[/tex] --- proportion without computer
So, the actual number is:
[tex]Number = p * n[/tex]
[tex]Number = 22.3\% * 5170000[/tex]
[tex]Number = 1152910[/tex]
[tex]Number \approx 1153000[/tex]
Hence: (B) is correct
Sophie invested 5,000 into an account that will increase in value by 2.3% each year. Write a function to model this situation, then find the value of the investment after 15 years
Answer:
$6725
Step-by-step explanation:
Given data
Princiapal= $5000
Rate=2.3%
Time= 15years
The function that will model this situation is given as
A=P(1+rt)
The above function is a simple interest function
Substitute our data we can find the amount A
A=5000(1+0.023*15)
A= 5000(1+0.345)
A=5000(1.345)
A=5000*1.345
A=$6725
Hence the value of the investment after 15 years is $6725
Write a quadratic function that has been translated 1
units to the right and 3 units down.
Step-by-step explanation:
Hi,
f(x) = (x - 1) - 3
The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)
And the -3 is not embedded with the x, meaning the function will move 3 units down.
I hope this helps :)
