HELP NEEDED: Will mark Brainliest to best answer!! The center of a dilation is (0,0) and the scale factor is 7. If A(3,4), then which is the distance between A and A prime? A. 5 B. 7 C. 30 D. 35
Answers
Answer:
C. 30
Step-by-step explanation:
Distance formula - [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}[/tex]
The scale factor of 7 is basically saying that the coordinates (3,4) are going to be increased 7 times.
3•7 = 21=x --> A prime = (21,28)
4•7 = 28=y
[tex]\sqrt{(21-3)^2+(28-4)^2}[/tex]
= [tex]\sqrt{324+676}[/tex]
= [tex]\sqrt{900}[/tex]
= 30

Answers
Answer:
$1715
Step-by-step explanation:
You have to find out what 25% of $6,860 is, which is the same as dividing the total by 4, since 1/4 = 25%. So,
$6,860/4=$1715

Select the correct answer from each drop-down menu. cos2x-cos4x/sin2x+sin4x cos2x+cos4x/sin2x-sin4x
Answers
Select the correct answer from each drop-down menu.
cos2x-cos4x/sin2x+sin4x = tan x
cos2x+cos4x/sin2x-sin4x = -cot x
The trigonometric equations have value tan x, -cot x .
What is a Trigonometric Ratios?Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.
The trigonometric equation is
(cos 2x - cos 4x )/(sin2x +sin4x)
cos A + cos B = - sin (A+B)/2 sin(A-B)/2
sin A - sin B = sin( A+B)/2 cos (A-B)/2
= (-sin 3x) sin ( -2x)/2)/( cos 3x cosx)
= sin 3x sin x/ (sin 3x) cos x
= tan x
The other equation is
(cos 2x +cos 4x)/(sin 2x- sin4x)
= cos 3x cosx/ cos3x sin(- x)
= - cot x

HELP!!!!Find the measurement of 4(Explain)
Answers
Answer:
26°
Step-by-step explanation:
The angle 5 is equal to angle 154° as these are both corresponding angles and corresponding angles are equal.
Angles on a straight line equal 180°, so if we take 154° from 180° we get angle 4, which is 26°
I hope that helped!
XY and WZ are parallel.
Angle 1 + 154° = 180° (Linear pair)
→ Angle 1 = 180 - 154
→ Angle 1 = 26°
Now, Angle 4 = Angle 1 (Alternative interior angles)
→ Angle 4 = 26°
Hence, we got the answer.

The number of hot dogs Ryan can eat varies directly with the amount of time he spends eating. If Ryan can eat 14 hot dogs in 6 minutes, how many hot dogs can he eat in 15 minutes?
Answers
Answer:
35
Step-by-step explanation:
If I am not correct I'm sorry.
If Ryan can eat 14 hot dogs in 6 min then he should be able to eat about 35 hot dogs in 15 mins.
14/6= 2.333...
so 2.333... x 15 would equal 35
I hope this helps.
Answer:
Ryan can eat about 34.5 hot dogs in 15 minutes
Step-by-step explanation:
You first need to find how many hot dogs ryan eats in one minute. By doing this you need to do 14 divided by 6 and that will get you to 2.3
Than you need to take that 2.3 and muliply it by the 15 minutes and than that would get you to your answer of 34.5 hotdogs in 15 minutes

Use the given endpoint Y and the midpoint M of YZ (there is a line over YZ) to find the coordinates of the other endpoint Z
Answers
The x-coordinate of our midpoint = 3
The x-coordinate of Y = 0
k = x-coordinate of Z
3 = (0 + k) / 2
Multiply both sides by 2
6 = k + 0
Simplify
6 = k
The y-coordinate of our midpoint = 3
the y-coordinate of Y = 5
w = y-coordinate of Z
3 = (w + 5) / 2
Multiply both sides by 2
6 = w + 5
Subtract 5 from both sides
1 = w
For problem #17, Z(6, 1)
Let's do problem 18 now.
The x-coordinate of our midpoint = 5
The x-coordinate of Y = -1
k = x-coordinate of Z
5 = (k + (-1)) / 2
Multiply both sides by 2
10 = k + (-1)
Simplify the right side
10 = k - 1
Add 1 to both sides
11 = k
The y-coordinate of our midpoint = 9
The y-coordinate of Y = -3
w = y-coordinate of Z
9 = (w + (-3)) / 2
Multiply both sides by 2
18 = w + (-3)
Simplify the right side
18 = w - 3
Add 3 to both sides
21 = w
For problem #18, Z(11, 21)

NO is an angle bisector. Solve for x.
A. x = -10
B. Not enough information
C. x = 10
D. x = 4
Answers
x= -10
Explanation:
When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.
