Step-by-step explanation:

The range of a function is the set of all possible output values (y-values).

From inspection of the given graph:

Therefore, the most appropriate range from the given answer options is:

Note:  The graph appears to be the exponential function  [tex]y=2^x-2[/tex]  with a horizontal asymptote at y = -2.  This means that the curve will get closer and closer to y = -2 as x approaches negative infinity, but it will never touch it.  The function approaches infinity as x approaches infinity.  Therefore, the range for this function is y > -2

The definition of a geometric sequence is given as follows:

[tex]a_n = a_1(r)^{n - 1}[/tex]

In which the terms are given as follows:

In a geometric sequence, each term is the multiplication of the previous term by the common ratio.

The sequence in this problem is given as follows:

(0.01, 0.02, 0.04, ...).

Hence the first term and the common ratio of the sequence are given as follows:

[tex]a_1 = 0.01, q = 2[/tex]

Thus the definition is of:

[tex]a_n = 0.01(2)^{n - 1}[/tex]

The income on the 31st day is of:

[tex]a_{31} = 0.01(2)^{30} = 10,737,418.24[/tex]

The sum of the first n terms of a geometric sequence is given as follows:

If an orchard has 468 pear trees and The number of rows exceeds the number of trees per row by 8. the number of trees that are in each row would be 18

We have to define T as the number of trees that are in a row.

Then we have to define t + 8 as the number of rows that we have

This would give us the equation that is written as

t(t + 8) = 468

then we would have

t² + 8t -468 = 0

We would have to find the factors of 468 which when inputted in the equation would give us the value 468

t(t + 8) = 468

This factor would be 18

such that

18 ( 18 + 8) = 468

18 * 26 = 468

468 = 468

Hence the number of trees that are in each row would be 18

Answer: N = 5

Step-by-step explanation:

The motion of the arrow, described by the kinematic equation for the height, h(t) = 60·t - 0.8·t² are as follows;

(a) The velocity after 1 second is 58.4 m/s

(b)  The arrow hits the moon after 75 seconds

(c) The velocity of the arrow when it hits the moon is 60 m/s

(d) The arrow reaches the maximum height  in37.5 seconds.

A kinematic equation is an equation that describes the motion of an object moving under constant acceleration.

The kinematic (equation) function for the height of the arrow is; h(t) = 60·t - 0.8·t²

The initial velocity of the arrow = 60 m/s

(a) The velocity of the arrow = The rate of change of the height, therefore;

v = h'(t) = 60 - 2 × 0.8·t = 60 - 1.6·t

The velocity after 1 second = h'(1) = 60 - 1.6 × 1 = 58.4

The velocity of the arrow after 1 second is 58.4 m/s

(b) When the arrow hits the moon, we get;

h(t) = 0, therefore;

h(t) = 60·t - 0.8·t² = 0

( 60 - 0.8·t)·t = 0

t =  0  or 60 - 0.8·t = 0

t = 60/0.8 = 75

The time the arrow hit the moon is 75 seconds after being shot

(c) The velocity of the arrow when it hits the moon is  found using the equation;

h'(37.5) = 1.6 × 37.5 = 60

The velocity when it hits the moon, the velocity is 60 m/s

(d) The motion of the arrow is symmetrical, therefore, the time it takes the arrow to reach the the maximal height is the time it takes the arrow to reach back to the moon surface, which indicates;

The time it takes the arrow to reach maximum height is half the time it takes the arrow to hit the moon after being shot = 75/2 seconds = 37.5 seconds

Answer: 1920

Step-by-step explanation:

The number of $ 5 bills = 3

The number of $ 10 bills = 6

The number of $ 20 bills = 15

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 total amount be = $ 375

Let the total number of bills = 24

Let the number of $ 5 bills be = x

Let the number of $ 10 bills be = y

Let the number of $ 20 bills be = z

The total number of $ 5 bills x = ( 1/2 ) x number of $ 10 bills

So , x = y/2

Now , the equation will be

The total number of bills = x + y + z

So , x + y + z = 24   be equation (1)

And ,

The total amount = 5x + 10y + 20z

So , 5x + 10y + 20z = 375

Divide by 5 on both sides , we get

x + 2y + 4z = 75   be equation (2)

On simplifying equation (1) and equation (2) , we get

x + y + z = 24

Substituting the value of y , we get

x + 2x + z = 24

3x + z = 24   be equation (3)

And ,

x + 2y + 4z = 75

x + 4x + 4z = 75

5x + 4z = 75   be equation (4)

Multiply equation (3) with 4 , we get

12x + 4z = 96   be equation (5)

Subtract equation (4) from equation (5) , we get

7x = 21

Divide by 7 on both sides , we get

x = 3

Therefore , the number of $ 5 bills is 3

Substitute the value of x , we get

y = 2x

y = 6

Therefore , the number of $ 10 bills is 6

Substitute the value for x and y in equation (1) , we get

x + y + z = 24

3 + 6 + z = 24

z + 9 = 24

Subtract 9 on both sides , we get

z = 15

Therefore , the number of $ 20 bills is 15

Hence ,

The number of $ 5 bills = 3

The number of $ 10 bills = 6

The number of $ 20 bills = 15

The image of the scaled copy of the square is M'(-14,-8), N'(-8,-6), O'(-6, -12), and P'(-12, -14)

Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.

From the question, we have the following parameters that can be used in our computation:

This means that

Scaled copy = Scale factor * Vertices of MNOP

So, we have

M'N'O'P' =M(-7,-4), N(-4,-3), O(-3, -6), and P(-6, -7)* 2

A function that relates the distance (d) traveled to the time (t) is d = 120t.

A graph of the function is shown in the image attached below and it is a linear function.

Mathematically, the slope-intercept form of a line can be calculated by using this equation:

y = mx + c

Where:

Next, we would use the given function in slope-intercept to complete the table of values as follows;

When y = 9, the value of x is given by:

y = 3x/2 + 3

9 = 3x/2 + 3

3x/2 = 9 - 3

3x/2 = 6

3x = 12

x = 12/3

x = 4.

When y = 6, the value of x is given by:

y = 3x/2 + 3

6 = 3x/2 + 3

3x/2 = 6 - 3

3x/2 = 3

3x = 6

x = 6/3

x = 2.

When y = 0, the value of x is given by:

y = 3x/2 + 3

0 = 3x/2 + 3

3x/2 = -3

3x = -6

x = -6/3

x = -2.

When y = -3, the value of x is given by:

y = 3x/2 + 3

-3 = 3x/2 + 3

3x/2 = -3 - 3

3x/2 = -6

3x = -12

x = -12/3

x = -4.

Mathematically, a constant of proportionality (speed) for this train's journey (distance) can be represented with the following mathematical expression:

Constant of proportionality (k) = 360/3

Constant of proportionality (k) = 120

Answer:

z = 15

Step-by-step explanation:

The sum S of the interior angles of a regular polygon is given by the formula

S = (n-2) x 180 where n is the number sides

Here n = 9

So S = (9-2) x 180 = 7 x 180 = 1,260

There are 9 interior angles and each angle is (5z + 65)

So the sum of all 9 interior angles = 9 (5z + 65)

= 45z + 585

Set these equal to each other and solve for z

45z + 585 = 1260

45z = 675

z = 675/45 = 15

The double integral is solved in two steps, first the inner integral is solved, and then the result of the inner integral is used to calculate the outer integral.

Considering the function and the region, the complete integral in this problem is given as follows:

[tex]\int_{-4}^{2}\int_{-4}^{2} (3x + y)dxdy[/tex]

Then the inner integral in this problem is given as follows:

[tex]I = \int_{-4}^{2} (3x + y)dx[/tex]

We are integrating the variable x, then the variable y is a constant, as thus the result is given as follows:

I = 1.5x² + xy, from x = -4 to x = 2.

Then, applying the Fundamental Theorem of Calculus, the result is given as follows:

I = 1.5(2)² + 2y - 1.5(-4)² + 4y = 6y - 18.

Then the outer integral is calculated as follows:

[tex]O = \int_{-4}^{2} 6y - 18[/tex]

Then the result is given as follows:

O = y² - 18y, from y = -4 to y = 2.
