Which types of dilation are the given scale factors? Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.
Answer:
Expansion
Contraction
Expansion
Contraction
Step-by-step explanation:
The correct type of dilation for given scale factors are 1) contraction, 2) contraction, 3) expansion 4) contraction
What is dilation?Dilation is a type of transformation in geometry, in which the original figure changes its scales, either reduce or enlarge.
Given are scale factors,
Scale factor symbolized by k,
We know that, when k > 1, the figure expands or enlarge.
When k < 1, the figure reduces or contract.
And when k = 1, the figure is congruent to the dilation.
1) -5 = (contraction)
1 > -5, therefore, figure is contraction.
2) -1/4 = (contraction)
1 > -1/4, therefore, figure is contraction.
3) 3.5 = (expanding)
1 < 3.5, therefore, figure is expanding.
4) 6/7 = (contraction)
6/7 = 0.8571 < 1, therefore, figure is (contraction)
Hence, -5 = (contraction), -1/4 = (contraction), 3.5 = (expanding) and 6/7 = (contraction)

Answer:
slope = 6x
Step-by-step explanation:
the formula to find slope between 2 points is "m = (y2 - y1)/(x2-x1)", or "m = rise/run". so when you plug in the numbers, you get "m = (12 - 6)/(2 - 1)", which gives you "m = 6/1", which is just 6x.
Answer:
Slope = 6
Step-by-step explanation:
From the graph we get:
(x1, y1) = (1, 6) and
(x2, y2) = (2, 12)
Slope = (y2 - y1) / (x2 - x1)
= (12 - 6) / (2 - 1)
= 6 / 1
= 6

Answer:
x=30 is the answer no hate if I'm wrong :)
Step-by-step explanation:
The sum of angles in a triangle is 180 so we add them all and we get x=30.
Then find the measure of each angle by substitution.
30=-6x+6
Solve the equation
Answer:
-4
Step-by-step explanation:
24 = -6x
-4 = x
............
Answer:
x = -4
Step-by-step explanation:
30 = - 6x + 6
- 6x = 30 - 6
- 6x = 24
- x = 24 / 6
- x = 4
x = - 4

Answer:
isosceles right
Step-by-step explanation:
The three angles total 180°, so you have ...
x° +x° +2x° = 180°
4x = 180
x = 45
2x = 90
The largest angle is a right angle (90°).
A triangle with measures of 45°, 45°, and 90° is an isosceles right triangle.

matt is standing on top of a cliff 305 feet above a lake. the measurement of the angel of depression to a boat on the lake is 42 degrees. how far is the boat from Matt?
Answer:
Distance of boat from Matt = 274.5 ft (Approx.)
Step-by-step explanation:
Given:
Height of cliff = 305 ft
Angle = 42°
Find:
Distance of boat from Matt
Computation:
Tan 42° = Distance of boat from Matt / Height of cliff
0.90 = Distance of boat from Matt / 305
Distance of boat from Matt = 274.5 ft (Approx.)
The measure of ∠A is 12° greater than the measure of ∠B. The two angles are complementary. Find the measure of each angle.
The m∠A is __° and m∠B is __°.
Answer:
39° = m∠A
51° = m∠B
Step-by-step explanation:
Complementary angles have a sum of their measures = 90
Let x = m∠B
then x + 12 = ∠A
m∠A + m∠B = 90
x + 12 + x = 90
2x + 12 = 90
2x = 78
x = 39° = m∠A
x + 12 = 39 + 12 = 51° = m∠B
The measure of ∠A is 39°.
The measure of ∠B is 51°.
Here,
The measure of ∠A is 12° greater than the measure of ∠B.
The two angles are complementary.
We have to find the measure of each angle.
What is Complementary angle?
Complementary angles have a sum of their measures is 90°.
Now,
The measure of ∠A is 12° greater than the measure of ∠B.
Let m∠B = x
Then, ∠A = x + 12
The two angles are complementary.
Hence,
m∠A + m∠B = 90
x + 12 + x = 90
2x + 12 = 90
2x = 78
x = 39°
And, x + 12 = 39 + 12 = 51°
Hence, The m∠A is 39° and m∠B is 51°.

The answer is the 3rd choice.
x cannot be 3 and 5 at the same time.
x = 3
x = 5
Subtract the first equation from the second equation.

2. A mother is three times as old as her daughter.
In 12 years' time she will be twice as old as her daughter will be then.
How old is the mother no.w?
Answer:
The mother is 36 years now.Step-by-step explanation:
x - the age of the daugther now
3x - the age of the mother now
x + 12 - the age of the daugther in 12 years' time
3x + 12 - the age of the mother in 12 years' time
The mother will be twice as old as her daughter will be then:
3x + 12 = 2·(x + 12)
3x + 12 = 2x + 24 {subtract 2x from both sides}
x + 12 = 24 {subtract 12 from both sides}
x = 12 (the age of the daughter now)
3x = 3·12 = 36

Step-by-step explanation:
Option A [tex][x+5=20][/tex]tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.Option B[tex][x=5][/tex] tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.Option C[tex][x<5][/tex] tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.Option D[tex][x+5][/tex] is an expression; It can't be called an equation or an inequality unless we relate it with another expression.Step-by-step explanation:

What is the average rate of change over the interval 1≤x≤3
9514 1404 393
Answer:
3
Step-by-step explanation:
The average rate of change is the slope of the line between the points at the ends of the interval: (1, -2) and (3, 4). That is given by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (4 -(-2))/(3 -1) = 6/2
m = 3
The average rate of change on the interval is 3.

The main height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
Complete Question
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
Answer:
Center Z score = 4.5
The score is unusual
Step-by-step explanation:
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
The formula for z score is:
z = (x-μ)/σ, where
x is the raw score = 6.9feet
μ is the population mean = 6feet
σ is the population standard deviation = 0.2 feet
Hence:
Z = 6.9 - 6/0.2
Z = 0.9/0.2
Z = 4.5
Yes this score is unusual
