Check all that apply.
Answer:
A and D are true.
Step-by-step explanation:
A function is a relationship that maps elements from one set (the domain, set of the inputs) into elements from another set (the range, set of the outputs), such that each element from the domain can be mapped into only one element from the range.
So, if the inputs are represented in the horizontal axis, and the outputs are represented in the vertical axis, when we draw a vertical line in any given point, this line can not intersect the graph more than once (because that would mean that a given input has two different outputs). This is known as the vertical line test. Note that two different values from the domain can be mapped into the same value in the range.
Also, we define a function as one-to-one if each output is mapped from only one input.
(so here we can not have two different inputs mapped into the same output).
Here we can do a similar test to the one above, this time we should use the horizontal line test to verify if the function is one-to-one or not.
So, here the correct options are:
A and D.
Option B is false.
And for option C, a sequence is a function where the variable is a set of natural numbers, so option C is also false.
Answer:
A and B is correct

If y^4-y^3-3 is multiplied by 2y^3-2, what is the coefficient of y^3 in the product?
A. -4
B. -2
C. -1
D. 1
E. 6
Answer:
-4
Step-by-step explanation:
[tex](y^4-y^3-3) \times (2y^3-2)=...+[(-1)(-2)+(2)(-3)]y^3+...\\=...+[2-6]y^3+...\\=...+(-4)y^3+...\\[/tex]
so coefficient of y^3=-4

Answer:
[tex] \displaystyle {r}^{} = 6[/tex]
Step-by-step explanation:
remember that,
[tex] \displaystyle V _{ \rm sphere} = \frac{4}{3} \pi {r}^{3} [/tex]
given that,
V=288πthus substitute:
[tex] \displaystyle \frac{4}{3} \pi {r}^{3} = 288\pi[/tex]
divide both sides by 4/3π:
[tex] \displaystyle {r}^{3} = 216[/tex]
cubic root both sides:
[tex] \displaystyle {r}^{} = 6[/tex]
and we are done!
Now solve this equation for y. Remember the roller coaster is above ground, so you are only interested in the positive root.
Answer:
[tex]y = \sqrt{ 900 - x\²[/tex]
Step-by-step explanation:
In the complete question, the area of the roller coaster is:
[tex]x\² + y^2 = 900[/tex]
Required
Solve for y
We have:
[tex]x\² + y^2 = 900[/tex]
Subtract [tex]x\²[/tex] from both sides
[tex]y^2 = 900 - x\²[/tex]
Take positive roots of both sides
[tex]y = \sqrt{ 900 - x\²[/tex]
find the volume of and round all answers to the nearest hundredth.
Answer:
The answer would be : 7,500 <-- (rounded)
Step-by-step explanation: How i got this answer is, i just multiplied all of the sides together since thats what you do with area's. ( 21 x 21 x 17= 7,497)
Now, the last step is to just round the number off. As we see, the "497" is much more closer to the number "500". So we can just simply round "497" to "500". So your final number for the area would be (7,500) ft.

During math class, Laura stated that the two cylinders shown below have the same volume. Jean interrupted Laura and argued that the volumes of the two cylinders are different. Their
eacher explained that Laura was correct.
Answer:
3rd option
Step-by-step explanation:
Cavalieri's principle states that two figures which have the same height and same cross-sectional area have the same volume
the height of the cylinders are both 42
the diameter of both figures is 24 as the diameter of the second cylinder = 12 x 2 = 24
the radius of the cylinders are both equal to 12
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
thus the volumes should be equal
A college cafeteria wants to know which lunch food is least popular. Which of the following groups should be interviewed to ensure that the survey results will not be misleading?

C. students who eat in the cafeteria
D. students’ families
Answer:
c. students who eat in the cafeteria
Step-by-step explanation:
it wouldnt help to include people who dont eat the food and therefore wont have an honest opinion about the food. They have to talk to the people who do eat the food, which are those who eat in the cafeteria
Slope-intercept from by steps
f f(1) = 160 and f(n + 1) = –2f(n), what is f(4)?
Answer:
Step-by-step explanation:
f(1) = 160
f(n + 1) = -2 * f(n)
n = 1
f(2) = -2*f(1)
f(2) = -2*160
f(2) = - 320
f(3) = - 2*f(2)
f(3) = -2 * - 320
f(3) = 640
f(4) = -2 * f(3)
f(4) = -2 * 640
f(4) = - 1280
The Ratio of Marbles is 3 green: 7 blue: 5 red. If a bag of marbles has 225 marbles in it,
how many green would you expect in the bag?
Answer:
45 green marbles
Step-by-step explanation:
Green : Blue : Red = 3 : 7 : 5
Fraction of green marbles = [tex]\frac{3}{3+7+5}=\frac{3}{15}[/tex]
Total marbles = 225
Number of green marbles = [tex]\frac{3}{15}*225[/tex]
= 3 * 15
= 45

A translation moves point B (-5,3) to point B’ (2,1). What is the image of (x,y) under this translation?
(X-3, y-2)
(X-3, y+2)
(X+7, y+2)
(X+7, y-2)
Answer:
4th option
Step-by-step explanation:
Given
B (- 5, 3 ) → B' (2, 1 )
The change in the x- coordinates are - 5 → 2 , that is + 7
The change in the y- coordinates are 3 → 1 that is - 2
Then the translation rule is
(x, y ) → (x + 7, y - 2 )
If translation moves point B (-5,3) to point B’ (2,1). Then (X+7, y-2) is the image of (x,y) under this translation
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given,
A translation moves point B (-5,3) to point B’ (2,1).
We need to find the image of (x,y) under this translation
A graph is translated k units horizontally by moving each point on the graph k units horizontally.
Which means to get B' which translation is used.
B (- 5, 3 ) and B' (2, 1 )
If we add +7 to x coordinate we will get 2.
When we subtract 2 from B we will get 1
So the translation rule is
(x, y ) → (x + 7, y - 2 )
Hence (X+7, y-2) is the image of (x,y) under this translation

Isaiah brought two dozen donuts to a class party. Half of the donuts had vanilla frosting with sprinkles, 2 had strawberry frosting with cream filling, and the rest had chocolate frosting with sprinkles. What fraction of the donuts had sprinkles? There are 12 donuts in a dozen.
Answer:
22/24
ALL TOGETHER there is 24 donuts.
take half of 24, or 24 divided by 2, and you get 12.
so we know 12 of the donuts are vanilla with sprinkles.
then 2 had strawberry frosting and the rest had chocolate and sprinkles.
we took 12 away so we only have twelve left and if 2 of those 12 are strawberry with no sprinkles and the rest are chocolate WITH sprinkles, this means 10 are chocolate with sprinkles.
so 10 chocolate and sprinkles +12 vanilla and sprinkles=22 donuts with sprinkles out of 24 donuts total
Answer:
22/24

two lines intersect.One has gradient 4 and y-axis intercept 3. The other has gradient 6 and cuts the y-axis at (0,1). What is the point of interesection of the lines?
Answer:
(1, 7 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Then the equations of the 2 lines are
y = 4x + 3 → (1)
y = 6x + 1 → (2)
Substitute y = 6x + 1 into (1)
6x + 1 = 4x + 3 ( subtract 4x from both sides )
2x + 1 = 3 ( subtract 1 from both sides )
2x = 2 ( divide both sides by 2 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (1)
y = 4(1) + 3 = 4 + 3 = 7
Point of intersection = (1, 7 )
Write an
equation of the line that passes through the points (-3,4) and (-5,1).

A parent deposits $2000 into their child's bank account. The account earns 4%
interest each year. Write an explicit function that represents the situation. *
A(t) = 2000(1.04)-1
A (t) = 2000(4)'
A(t) = 2000(1.04)'
A(t) = 2000 + 4t
O
Answer:
A = 2000(1.04)^t
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
P is the principal = $2000
r is the rate = 4% = 0.04
On substituting
A = 2000(1+0.04)^t
A = 2000(1.04)^t
Hence the required expression is A = 2000(1.04)^t
