Answer:

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

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

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

Answer:

y = 3x + 1

Step-by-step explanation:

The y - intercept is +1

And the rise over run = 3/1  (because 3 is also 3/1)

Answer:

A) y=3x+1

1 is the y-intercept (it is on the y axis)

you start at the 1 on the graph where the line passes through, then go 3 squares up and 1 to the right to land on the line again. This is rise over run, which you rise 3 squares up from 1, then run 1 square to the right. 3/1 = 3

Answer:

it's 5

Step-by-step explanation:

Answer:

r = 5

Step-by-step explanation:

if x and y are proportional then 'y = rx' where 'r' is the constant of proportionality

35 = 7r

60 = 15r

100 = 20r

'r' is 5

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

Answer:

1.78 hours

Step-by-step explanation:

If t varies inversely with the speed, the formula for that is  t= \frac{k}{r} .  If t = 2 and r = 40, then we can solve for k, the constant of variation.  Multiply both sides by 40 to get  k = 80.  Now we need to find the value for t when r = 45.  Using the k value we just solved for, we will fill in the equation as  t= \frac{80}{45}   for a t value of about 1.78 hours

____________

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

[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]

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

[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,

thus 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:
