The triangles shown are similar. Which similarity statement expresses the relationship between the two triangles?

2 answers:

4 0

The answer is triangle PRQ is similar to triangle XWY because the order of the angles correspond with the angles that have the same angle measurement. Angle p is the first one and has a measure of 86. Angle x is the first one and also has a measure of 86 and so on. They are similar because AAA is not a postulate that can prove congruency. This means that 2 triangles can have the same angle measurements and different side lengths. However, triangles with all of the same angles are similar.

The domain and f^1(x)

TEA [102]

To solve for the inverse, just swap the x and y and solve for the new y.

$y=\sqrt{x} -8$

$x=\sqrt{y}-8$

$x+8=\sqrt{y}$

$(x+8)^2=y$

Then inspect both functions for the domain.

In the original function, x has to be greater than or equal to 0 or else you would have a negative square root which is impossible.

The inverse function has no limitations as any x could make that true.

The main things that will limit domain is square root of negative or divide by zero.

Therefore, x>=0 is the only domain restriction.

The area of the trapezium is 63cm and the top is 6cm and the bottom is 12cm what’s the height

steposvetlana [31]

Answer:

height = 7 cm

Step-by-step explanation:

The area (A) of a trapezium is calculated using the formula

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the parallel bases

here a = 6, b = 12 and A = 63, hence

$\frac{1}{2}$ × h × (6 + 12) = 63

$\frac{1}{2}$ h × 18 = 63

9h = 63 ( divide both sides by 9 )

h = 7

A snowstorm began on Monday evening. It snowed steadily until 6:00 am on Tuesday morning when the snow was 12 inches deep. Kevin

poizon [28]

Answer:

what is expected at 7am is 15 inches deep snow but what we have is 12 inches deep snow. The equation has failed in its prediction.

Step-by-step explanation:

In this question, we are asked to calculate if the prediction made by an equation modeled is correct.

Firstly let’s look at the equation in question;

y = 3t - 6

where y is the snow depth and t is the number of hours after midnight.

now we are looking at 7am, that’s 7 hours past 12am, meaning 7 hours after midnight.

let’s plug the value of t as 7 into the equation

y = 3(7) - 6

y = 21-6

y = 15 inches

according to the equation by Kevin, what is expected is 15 inches deep snow but what we have is 12 inches deep snow. The equation has failed in its prediction.
