Quadrilateral WXYZ has vertices W(–3, 4), X(–3, 1), Y(2, 1), and Z(2, 4). What are the coordinates of the image of point W after a reflection across the y-axis?
A. w-(3, 4)
B. w- ( 3 , - 4 )
C. w- ( - 3 , - 4 )
D. w- ( 4 , - 3 )
Answer: A
Step-by-step explanation:
When you reflect over the Y axis you do (-x,y)
And so (-3,4) = (3,4)
Mateo is studying a human hair with a diameter of 6.5 x 10-4 inches and a horse hair with a diameter of 1.3 x 10-3 inches. Which statement is true?
Answer:
The diameter of horse hair is twice as thick as the diameter of the human hair.
Step-by-step explanation:
The diameter of a human hair = [tex]6.5\times 10^{-4}\ \inches[/tex]
The diameter of a horse hair = [tex]1.3\times 10^{-3}\ \inches[/tex]
Dividing the diameter of a horse hair to the diameter of a human hair as follows :
[tex]\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{6.5\times 10^{-4}}{1.3\times 10^{-3}}\\\\\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{1}{2}\\\\\text{Diameter of horse hair}=2\times \text{Diameter of human hair}[/tex]
So, the diameter of horse hair is twice as thick as the diameter of the human hair.
Answer:
The horse hair is 2 times as thick as the human hair.
$420 is divided between A, B and C. B receives $20 less than A, and C receives half as much as A and B together. how much does each receive?
Also could you explain the answer?
Answer:
A = $150
B = $130
C = $140
Step-by-step explanation:
Let the amount received by a be $x
b receives $20 less than a;
we have that;
b = x - 20
c receives half of Sum A and B
c = (x + x-20)/2
c = (2x-20)/2
c = x - 10
Add all and it gives 420
x - 10 + x -20 + x = 420
3x -30 = 420
3x = 420 + 30
3x = 450
x = 450/3
x =$150
a = 150
b = x - 20; 150 - 20 = 130
c = x-10
c = 150-10
c = $140
A room is 12 feet wide by 35 feet long. How far (in feet) is it from one corner of the room to the opposite corner measuring diagonally?
Answer:
The Correct Answer is 37 feet long.
Step-by-step explanation:
The Calculator can confirm, if we know that the 2 sides small sides are 12 and 35 we know that the hypotenuse is 37 feet long, therefore your answer is...
37 feet long

Answer:
A. (x, y) -> (0.2x, 0.2y)
Step-by-step explanation:
I'll test this out with just point S if that's fine.
Point S's coordinates are (5, -5), as seen on the coordinate plane.
However, Point S' has coordinates of (1, -1).
Divide 1 by 5 to get 1/5. You can also do -1/-5 to also get 1/5 (Remember, dividing two negatives gets you a positive.).
So you can conclude that the dilation has the x and y coordinates shrinking to 1/5 of the original. Both coordinates shrink at the same rate, so B and C are out. The figure is NOT getting bigger so D is also incorrect. This leaves A ((x, y) -> (0.2x, 0.2y)) as our answer.

In ΔHIJ, i = 6.6 inches, j = 6.4 inches and ∠H=62°. Find the length of h, to the nearest 10th of an inch.
Law of cosine helps us to know the third side of a triangle. The length of the third side of the ΔHIJ, h is 6.698 inches.
What is the Law of Cosine?The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,
[tex]c =\sqrt{a^2 + b^2 -2ab\cdot Cos\theta}[/tex]
where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
As it is given that the length of the first two sides of the triangle is i=6.6inches and j=6.4 inches, while the measure of the ∠H=62°. Therefore,
the length of the third side with the help of cosine rule can be written as,
[tex]h =\sqrt{i^2 + j^2 -2ij\cdot Cos(\angle H)}\\\\h =\sqrt{(6.6)^2 + (6.4)^2 -(2 \times 6.6 \times 6.4)\cdot Cos(62^o)}\\\\h = 6.6976 \approx 6.698[/tex]
Hence, the length of the third side of the ΔHIJ, h is 6.698 inches.
