A- z=15
B- z= 20
C- z=23
D- z=41

Answers

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

If an arrow is shot straight upward on the surface of the moon with initial velocity 60m/s, its height after t seconds is given by h(t) = 60t - 0.8t². (a) What is the velocity of the arrow after 1 second? (b) At what time t > 0 will the arrow hit the moon? (c) What is the velocity of the arrow when it hits the moon? (d) At what time does the arrow reach its maximal height?​ Show your working out!

Answers

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.

What is a kinematic equation?

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

9                    4

6                    2

0                    -2

-3                   -4

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.

How to complete the table of values?

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

y = mx + c

Where:

m represents the slope.x and y are the points.c represents the y-intercept.

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.

How to write a function for the distance and time?

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

Where:

d represents the distance.t represents the time.k represents the constant of proportionality (speed).

Next, we would determine the constant of proportionality (k) as follows:

Constant of proportionality (k) = d/t

Constant of proportionality (k) = 360/3

Constant of proportionality (k) = 120

Therefore, the required function that relates the distance (d) and time (t) is given by;

d = kt

d = 120t

What is dilation?

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.

How to determine the image of the scaled copy of the square?

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

Square MNOP with vertices M(-7,-4), N(-4,-3), O(-3, -6), and P(-6, -7): Scale factor of dilation, k = 2

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

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

How to solve for the number of trees

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

Which statement concerning the need for an autopsy would apply to this client?The coroner must be notified to determine the need of an autopsy the economic model pattern that describes concentric circles of similar economic/agricultural activities around a central market/business district is known as: how can a monopolistic competitor tell whether the price it is charging will cause the firm to earn profits or experience losses? a client suffering from chronic obstructive pulmonary disease (copd) reports that it is hard to cough up secretions and the secretions are thick and sticky. which intervention will the nurse use to promote respiratory hygiene in this situation? the incorporates a point of view toward the material dramatized in the script, a comedy or tragedy for example, whereas the must understand this point of view and translate it in ways appropriate for the production. (1)Many animals, including some insects, use visual clues to find their way. (2)For example, the female digger wasp lays eggs in a burrow in the soil. (3)She then flies off to capture her prey, which she stores in the burrow to feed her offspring when they hatch. (4)The famous animal-behavior scientist Niko Tinbergen studied the cues used by the female to relocate her burrow. (5)While the female was inside, Tinbergen surrounded the nest with pine cones. (6)When the wasp emerged, she flew around the nest before departing. (7)While she was gone, Tinbergen moved the cones about a foot away. (8)The returning wasp still sought her nest within the ring of cones. (9)Although the nest was in plain sight nearby, she was unable to locate it because the visual landmarks on which she relied had been shifted.(10)Birds may also use landmarks, such as rivers and seashores, to find their way. (11)Several species migrate at night or over large expanses of ocean, using the position of the sun or stars to tell direction. (12)Many species seem to have genetically programmed information about the direction of the sun at various times of day, and also possess a biological clock that measures off a roughly twenty-four-hour day. (13)Other birds have the remarkable ability to read the night sky. (14)Indigo buntings, for example, seem to have a built-in star map that enables them to find which direction is north, during spring migration, by looking at the stars.Question4. The passagea. lists examples of the central idea.b. shows causes for the central idea.c. defines and illustrates a term.d. presents all of the major details in time order.

Using evidence from the cross-section, explain why this statement is true or not. A helium-neon laser emits light with a wavelength of 633 nm. What is the frequency of this light. Alto and Sheryl both worked hard over the summer. Together they earned a total of $500. Sheryl earned $100 more than Alto. (a) Write a system of equations for the situation. Use s for the amount Sheryl earned and a for the amount Alto earned. (b) Graph the equations of the system on the graph provided on the next page. a. Note: Insert->Shape will allow you to add lines, draw dots, and otherwise insert shapes in both Microsoft Word and LibreOffice. The graph should be big enough for you to easily plot points using this method. b. If you do not want to graph using the drawing tools built into Microsoft Word or LibreOffice you may also print out, graph by hand, and scan the page. Please note its perfectly okay to upload multiple files. (c) Use Elimination or Substitution to solve the system. (d) Use your graph to estimate how much each person earned, check your work with part C, and explain your results in complete sentences.
