It preserves angle measurements and each side it multiplied by 2
Answer:
C (see attached)
Step-by-step explanation:
Similar right triangles will have the same ratio of short side to long side as the original.
That ratio for the given triangle is ...
(3/2)/2 = 3/4

For the answer choices, (left-to-right) as supplied in this problem statement, the ratios are ...
a) 2/2 = 1 . . . . . both sides are the same length
b) 1/(3/2) = 2/3

x =
Answer:
2.25
Step-by-step explanation:
Because if you do 8/6 you get 1.33333333333 so you would need to do 3/1.33333333333 and you would get 2.25.
Answer:
x = 2.25
Step-by-step explanation:
Since this is simply a reduction of a figure, we can assume the ratio is constant. With this in mind, we can set up the following proportion to solve for x.
8 / 3 = 6 / x
8 * x / 3 = 6
8 * x = 6 * 3
x = 6 * 3 / 8
x = 18 / 8
x = 9 / 4 = 2.25

Which statements about the graph of the function f(x) = –x2 – 4x 2 are true? Select three options.
The domain of the function is the real number and the range of the function is (-∞, 6].
What is a function?The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The function f(x) = -x² - 4x + 2
The function can be written as
[tex]\rm f(x) = -x^2- 4x +2\\\\f(x) = -x^{2}- 4x - 4 + 4 +2 \\\\f(x) = -(x^{2} +4x +4) + 6\\\\f(x) = -(x+ 2)^2 + 6[/tex]

2. At a school shop, pens are sold at dallars each and ruler at y dollars each. Mr. James bought 4 pens and 5 rulers for $20. Mr. Pike bought 2 of the same pens and 4 of the same ruler for $16 a. Write two equations in and y to represent the information given above. b. Solve the equations
Help pleaseee :)
Answer:
x = 0, y = 4
Step-by-step explanation:
1 pen = x dollars
4 pen = 4x
1 ruler = y dollars
5 rulers = 5y
now,
a) = 5y + 4x = 20
2x + 4y = 16
Now,
2x + 4y = 16
or, 2x = 16 - 4y
or, x = (16 - 4y)/2
Now,
5y + 4x = 20
or, 5y + 4{(16 - 4y)/2} = 20
or, (10y + 64 - 16y) = 40
or, 64 - 6y = 40
or, 64 - 40 = 6y
or, 6y = 24
so, y = 4
now,
x = (16 - 4(4))/2
or, x =(16 - 16)/2
so, x = 0
A plane can fly 312 miles with the wind in 3 hours, while it takes the same plane 4 hours to fly the same distance against the wind. Find the speed of the plane in still air, and the speed of the wind.
The speed on the plane is 104mph while that of the wind is 78mph
Speed and distancesThe formula for calculating distance is expressed as:
Speed = Distance/Time
If the plane is flying with the wind;
3(r+ w) = 312
r + w = 104 ................... 1
If against the wind
4(r - w )= 312
r- w = 78 .................. 2
Add both equations
2r = 104 + 78
2r = 182
r = 91
Since r + w = 104
w = 104 - 91
w = 13
Speed on the plane = r + w = 91 + 13 = 104mi/hr
Speed on the wind = 91 - 13 = 78mi/hr

The equatin of line AB is y = 2x + 4. What is the equation of a line parallel to line AB in slope-intercept form that contains the point (3, -2)2
Answer:
Step-by-step explanation:
Parallel lines have the same slope, so if the slope of the given line is 2, the slope of the "new" line is also 2, and the slope-intercept equation becomes:
y = 2x + b.
Here you seem to have a "misprint," as "(3, -2)2 is not a valid expresion.
Supposing that y ou meant (3, -2), then our equation becomes
-2 = 2(3) + b, or -8 = b.
The desired equation is then y = 2x - 8
If this is not what you expected, please focus on your (3, -2)2 and rewrite it properly.

Answer:
10 terms
Step-by-step explanation:
equate the sum formula to 55 and solve for n
[tex]\frac{1}{2}[/tex] n(n + 1) = 55 ( multiply both sides by 2 to clear the fraction )
n(n + 1) = 110 ← distribute parenthesis on left side
n² + n = 110 ( subtract 110 from both sides )
n² + n - 110 = 0 ← in standard form
Consider the factors of the constant term (- 110) which sum to give the coefficient of the n- term (+ 1)
the factors are + 11 and - 10 , since
11 × - 10 = - 110 and 11 - 10 = + 1 , then
(n + 11)(n - 10) = 0 ← in factored form
equate each factor to zero and solve for n
n + 11 = 0 ⇒ n = - 11
n - 10 = 0 ⇒ n = 10
However, n > 0 , then n = 10
number of terms which sum to 55 is 10
Given f(x) = 2x2 – x+ k, and the remainder when f(x) is divided by x – 1 is 3,
then what is the value of k?
Given :-
f(x) = 2x² - x + k .When f(x) is divided by (x-1) , the remainder is 3 .To Find :-
The value of k .Solution :-
Here we are given that ,
→ f(x) = 2x² - x + k
By Remainder Theorem , if f(x) is divided by x-a , then the remainder is f(a) .Hence here is f(x) is divided by x-1 , then the remainder will be f(1) . On substituting x = 1 , we have ,→ f(x) = 2x² - x + k
→ f(1) = 2(1)² - 1 + k
f(1) = 3 ,→ 3 = 2*1 -1 + k
→ 2 -1 + k = 3
→ k +1 = 3
→ k = 3-1
→ k = 2
Hence the value of k is 2 .

Mrs. Nguyen thought that she had $40 in her wallet. She actually has $48. What is her percent error? (Round to the nearest percent.)
Explanation:
Her guess is off by 8 dollars (since 48-40 = 8) and this is out of the true value of 48
So 8/48 = 1/6 = 0.1667 = 16.67% approximately is the percent error
This rounds to 17%
