Answer:

It doesn't form a right triangle

Step-by-step explanation:

According to the Pythagorean theorem, the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

a^2 + b^2 = c^2 by substituting the three values, 10, 15, and 20 you should get an equivalent value of the hypotenuse.

10^2 + 15^2 = 20^2

100 + 225 = 400

325 =/= 400

This is false.

Since this is not equivalent, it is NOT a right triangle.

Hope this helped :)

Answer:

The weighted average for the following score is $W = 85.72$

Step-by-step explanation:

From the question we are told that

The worth of the lab score is 23% of total grade i.e 0.23

The worth of each major test is 22.5% of the total grade 0.225

The worth of the final exam is 32% of the total grade 0.32

The score on lab is 85

The score on first major test is 95

The score on the second major test is 91

The score on the final exam is 76

Generally the weighted average is mathematically represented as

$W = [0.23 * 85 ]+ [0.225 * 95] + [0.225 * 91 ]+ [0.32 *76 ]$

=> $W = 85.72$

Which is the equation of a line that passes through the point (3,-4) and has a slope of 2.

Travka [436]

Answer:

y = 2x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = 6 + c ⇒ c = - 4 - 6 = - 10

y = 2x - 10 ← equation of line
