Answer:
Part a) 45 degrees
Part b) The image looks the same as the original, the vertices rotate around point M in three steps of 45 degrees each (see attached image)
Step-by-step explanation:
Part a)
Notice that since this is a regular figure with 8 sides, in order to find the angle subtended by each, we divide 360 degrees into 8 parts, and that gives us a measure of : 360 / 8 = 45 degrees
So each angle measures 45 degrees, and also the requested angle AMB
m AMB = 45 degrees.
Part b)
Notice that a rotation of 135 degrees is equivalent to 3 rotations of 45 degrees, since 45 x 3 = 135
Then as we rotate the image around the center M in 3 chunks of 45 degrees, we are going to end up in a figure that looks exactly like the original one, but the only thing is that we see the names of the vertex in different positions. Vertex A goes now to where vertex F was. Vertex B goes to where vertex G was, etc. Please see attached imagewhere the new vertex are denoted in red.

How many terms are in the expression 32abc + 17ab -14bc -5?
Hey there! I'm happy to help!
A term is anything in an expression that is added. If you see a - sign it is still a term it is just adding a negative number.
We are adding 32abc, 17ab, -14bc, and -5, so this is four total terms.

Given f(x)=13(4−x)2, what is the value of f(16)?
Answer:
1872
Step-by-step explanation:
Plug is 16 for x
f(x)=13(4−x)^2
f(16)=13(4−16)^2
f(16)=13(-12)^2
-12^2=144
f(16)=13(144)
f(16)=1872
Hope this helps! Plz award Brainliest : )
The value of function f(x)= 13(4 - x)² at x= 16 is 1872.
To find the value of f(16), we substitute x = 16 into the expression for f(x) and evaluate it.
f(x) = 13(4 - x)²
Substituting x = 16:
f(16) = 13(4 - 16)²
Now, let's calculate:
f(16) = 13(-12)²
= 13(144)
= 1872
Therefore, the value of f(16) is 1872.

Enter your answer, including the inequality symbol, in the boxes.
Answer:
[tex]x\leq6\text{ or } x>30[/tex]
Step-by-step explanation:
We are given the compound inequality:
[tex]\displaystyle 9x+4\leq 58\text{ or } \frac{1}{6}x-2>3[/tex]
Note that this is an "or" inequality. In other words, we just have to solve each inequality individually and then combine the answers!
1)
We have:
[tex]9x+4\leq58[/tex]
Subtract 4 from both sides:
[tex]9x\leq54[/tex]
Divide both sides by 9:
[tex]x\leq6[/tex]
So, our first solution is all numbers less than or equal to 6.
2)
We have:
[tex]\displaystyle \frac{1}{6}x-2>3[/tex]
Add 2 to both sides:
[tex]\displaystyle \frac{1}{6}x>5[/tex]
To cancel out the fraction, let's multiply both sides by 6. So:
[tex]\displaystyle 6\left(\frac{1}{6}x\right)>6(5)[/tex]
The left side will cancel. Therefore:
[tex]x>30[/tex]
So, our second solution is all numbers greater than 30.
Therefore, our full solution will be:
[tex]x\leq6\text{ or } x>30[/tex]
And we're done!

Samantha went to the store to buy cereal, milk and bread. The cereal cost $3.68. The milk cost $3.53 and the bread cost $2.14. If Samantha gave the clerk $10.00, how much change did she receive?
Answer:
$0.65
Step-by-step explanation:
The cereal ($3.68) + the milk ($3.53) + the bread ($2.14) costs a total of $9.35. If Samantha gave the clerk $10.00, she'd receive 65 cents back.
$10.00 - ($3.68 + $3.53 + $2.14) = $0.65

The world population is estimated to be 7.8 billion in 2020, and growing at an instantaneous rate of 1.05%. (a) Estimate the population in 2100 if the growth rate remains constant at 1.05%. (b) Estimate the population in 2100 using the logistic function, assuming a carrying capacity of 13 billion. Also, what will be the growth rate in 2100
Answer:
Population in 2100 is 17.99 billion.
Step-by-step explanation:
The population of the world in 2020 = 7.8 billion.
The growth rate = 1.05%
Now find the population after 2100. Use the below formula to find the population.
Population in 2100 = Population of 2020 (1 + growth rate)^n
Population in 2100 = 7.8 (1 + 0.0105)^80
Population in 2100 = 17.99 billions.
Now, find the growth rate in 2100.
dN/dt = [r N (K – N) ] / K
r = Malthusian parameter
K = carrying capacity.
Now divide both sides by K, now x = N/K then do the differential equation.
dx/dt = r x ( 1- x)
Now integrate, x(t) = 1/ [ 1 + (1/x – 1) c^-rt
From the first equation = dN/dt = (13 – 7.8) / 80 = (r × 7.8×(13 – 7.8) / 12
0.065 = (r × 7.8× 5.2) / 12
0.065 = r × 3.38
r = 1.92%
Solve. 9(4h - 6) = 2( -13 - 2h)
Answer: h= 7/10
Step-by-step explanation:
9(4h - 6 ) = 2(-13 - 2h) Distribute on both sides
9(4h) + 9(-6) = 2(-13) + 2(-2h)
36h - 54 = -26 - 4h Add 4h to both sides
+4h +4h
40h - 54 = -26 Add 54 to both sides
+54 +54
40h = 28 Divide both sides by 40
h = 7/10
Answer:
h= 7/10
Step 1: Remove the parentheses
9(4h - 6) = 2( -13 - 2h) = 36h-54= -26 -4h
Step 2: Move the terms
36h-54= -26 -4h = 36h+4= -26 + 54
Step 3: Calculate like terms
36h+4= -26 + 54 = 40h=28
Step 4: Divide both sides
40h=28 = h= 7/10
(In decimal form - h=0.7)

a jogger runs 218 meters eastward then 72 meters westard then 62 meters eastward and finally 184 meters westward. For this motion what is the distance moved
Answer:
Total distance = 536 m
Total displacement = 24 m
Step-by-step explanation:
Distance and Displacement
A moving object constantly travels for some distance at defined periods of time. The total moved distance is the sum of each individual distance the object traveled. It can be written as:
dtotal=d1+d2+d3+...+dn
This sum is obtained independently of the direction the object moves.
The displacement only takes into consideration the initial and final points of the path defined by the object in its moving. The displacement, unlike distance, is a vectorial magnitude and can be even zero if the object starts and ends the movement at the same point.
For the question at hand, it's not known if the requirement is about the distance or the displacement, so we will compute both.
To compute the distance, we just add all the distances:
dtotal= 218 m + 72 m + 62 m + 184 m = 536 m
To compute the displacement, we must establish a positive direction as desired. Let's choose the east as the positive direction. Any movement eastward is considered positive and any movement westward is negative. We mentioned the displacement is a vector, but since we only have movement in the x-axis, we can only manage the signs. Thus, the total displacement is:
xtotal = 218 m - 72 m + 62 m -- 184 m = 24 m
Since the result is positive, the jogger stopped 24 meters eastward form the original point.

Determine the slope and y intercept. Y=3/2x+3
Slope: 3/2 (the coefficient of x)
Y-Intercept: (0,3) (substituting x = 0 into the equation)
Ans: Yellow
Slope of the line [tex]Y=\frac{3}{2} x+3[/tex] is [tex]\frac{3}{2}[/tex] and the y intercept is [tex](0,3)[/tex].
We have equation of the line is[tex]Y=\frac{3}{2} x+3[/tex]
As the standard form of the equation is [tex]y=mx+b[/tex] where m is the slope.
Now, here [tex]m=\frac{3}{2}[/tex]
So slope of the line is [tex]\frac{3}{2}[/tex]
Now, for y intercept put x=0, we get
[tex]y=\frac{3}{2}0+3\\y=3[/tex]
So y intercept is (0,3).
