Answer:
P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)
Step-by-step explanation:
The translation vector, ⟨−6,3⟩, can be used to derive a rule for the translation of the coordinates: (x,y)→(x−6,y+3).
Apply the rule to translate each of the three preimage vertices to the image vertices.
P(−4,−5)→P'(−10,−2)
L(1,−7)→L'(−5,−4)
K(−9,8)→K'(−15,11)
Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.
Answer:
P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)

K(−9,8)→K'(−15,11)
Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.
the sum of six interior angles of a regular octagon is 800 the other two angles are equal find the size of each angle
An octagon is a polygon with 8 sides and angles. The two equal angles are 140 degrees each
How to calculate the sum of an interior angle of a polygon?An octagon is a polygon with 8 sides and angles
The formula for calculating the sum of interior angle of a regular polygon is expressed as:
S = (n-2) * 180
If the sum of six interior angles of a regular octagon is 800 the other two angles are equal, then;
800 + 2x = (8-2)*180
800 + 2x = 1080
2x = 1080 - 800
2x = 280
x = 140

c. How long will it take the ball to be 56 ft above the ground?
No answer text provided.
(a) The vertical motion equation for the ball is h = 8 + 48t - 16t².
(b) The time for the ball to hit the ground is 3.15 s.
(c) The time for the ball to travel 56 ft above the ground is 0.79 s.
Vertical motion equation for the ball
The vertical motion equation for the ball is calculated as follows;
h = h₀ + vt - ¹/₂gt²
h = 8 + 48t - ¹/₂(32)t²
h = 8 + 48t - 16t²
Time for the ball to hit the ground0 = 8 + 48t - 16t²

what is the surface area, in square inches, of the rectangular prism formed by folding the next below?
Therefore, the surface area of the rectangular prism is 2600 square inches.
What is surface area?In geometry, surface area is the total area that the surface of a 3-dimensional object covers. It is the sum of the areas of all the faces or surfaces that make up the object. Surface area is often used to determine the amount of material needed to cover an object or to calculate the heat transfer between an object and its surroundings.
Here,
To find the surface area of the rectangular prism, we need to find the area of each of its faces and add them together. Looking at the net, we see that there are three pairs of identical rectangles: the top and bottom faces, the front and back faces, and the left and right faces. Each of these rectangles has dimensions of 23 inches by 8 inches.
Therefore, the surface area of the rectangular prism is:
=2 * (23 in. * 8 in.) (top and bottom faces)
=2 * (36 in. * 8 in.) (front and back faces)
=2 * (23 in. * 36 in.) (left and right faces)

To use the tree house as the start of the zip line, the cable needs to be attached to
the starting tree at a height 18 feet above the ground.
To meet the slope constraint, Esteban wants to change the height 7 feet and end the
zip line at a height 11 feet above the ground. He claims this vertical change meets the
slope constraint.
Test Esteban's claim for Tree A and Tree B. Use specific numbers from the situation to
justify or refute whether having a vertical change of 7 feet will satisfy the slope
constraint for each tree.
For both tree A and tree B calculated slope is less than 0.06. Then it does not satisfy the slope constraint.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

Answer:
(x+6)^2+3
Step-by-step explanation:
translate 6 left
left is negative
so (x+6)^2. it is + because the x goes in the opposite direction causing (x-6)^2 to go right
and 3 units up so add x by 3 to get (x+6)^2+3
Answer:
g(x) = (x + 6)² + 3
Step-by-step explanation:
To move horizontally replace each x with (x ± c)
if you move it to the right, you need x - c
if you move it to the left , you need x + c
Since we are moving to the left 6, we will have: g(x) = x² + 6
To move up or down, add or subtract the constant equal to the units moved, so to move it up 3 would give us:
g(x) = (x + 6)² + 3

Bart wants to deposit his piggy bank savings into a savings account. If he deposits $325. 76, how many whole years will it take, at 2% simple
Interest, for that amount to grow to $400. 00?
A. 12 years
B. 4 years
C. 16 years
D. 8 years
Answer:
Step-by-step explanation:
Compounding interest :
Future value of money = Present value * (1+ r)^N
r - interest rate
n - number of period
In our example, Present value = 325.76, FV = 400, r = 2%, and we need to find N
by solving that we can find it that N is equal to 10.3675
Simple interest :
400 - 325.76 = 74.26$ we need to increase
325.76*2% = 6.5152$ each year
74.26 / 6.5152 = 11.3949
as a whole year = 12years
Which statement is correct about the period of the function y = sin x?
A) There are 180° in a unit circle, so the period is 180°
B) There are 180° in a unit circle, so the period is 360°
C) There are 360° in a unit circle, so the period is 180°
D) There are 360° in a unit circle, so the period is 360°
Answer:
C
Step-by-step explanation:
The function sine of 'x' repeats its value after a full rotation of π radians. In degrees, that would be 180 degrees. On a unit circle, the sine is the y-component at any point along the circumference of the circle. In the first two quadrants, the y-component is the exact same until you exceed a rotation of 180 degrees. The degree of a circle is 360 degrees, therefore the answer would be C.

Chloe gave out a survey to some students in her school about their favorite color. 219 of those surveyed said their favorite color was purple. If 73% of the students surveyed said their favorite color was purple, how many students were surveyed in total?
If 73% of the students surveyed said their favorite color was purple, 1,000 students were surveyed in total.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Let the total number of persons surveyed be x. However, the question tells us that 350 respondents, or 35% of this x, make up the total.
Hence, mathematically, we have;
73% of x = 219
(73/100) × x = 219
73x = 100×219
73x = 219,000
x = 219,000/219
x = 1,000 students
Thus, if 73% of the students surveyed said their favorite color was purple, 1,000 students were surveyed in total.
