You are not correct. Here's an explanation as to why: First of all, the triangle is isosceles, since it has two congruent sides that leads to the conclusion of two congruent angles, one opposite each side. This means that all three angle measurements of the triangle are x degrees, x degrees, and 40 degrees. To solve for x, add all three values together and set them equal to 180 degrees, the sum of three angles in any triangle. Your mistake is adding only one x to 40, which isn't inclusive of all three triangles. I hope this helped!

what do the average rates of change of the function y= x+2 over the intervals {-2,0],[0,3], and [-2,3] indicate about the functi

kakasveta [241]

Answer:

The function is linear

Step-by-step explanation:

<u>Given function:</u>

y = x + 2

It is a line with the slope of 1.

Average rate of change is same in any interval of the linear function and it equals to the rate of change or slope of the line.

You can calculate the average rate of change in the given intervals and you will always get the value of 1.

What is the image of the point (0,5)(0,5) after a rotation of 180^{\circ}180

almond37 [142]

The image of the point (0,5) after a rotation of 180° counterclockwise about the origin is (0, -5).

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is:

What is the image of the point (0,5) after a rotation of 180° counterclockwise about the origin?

The rule for the above transformation:

(x, y) → (-x, -y)

(0, 5) → (0, -5)

Thus, the image of the point (0,5) after a rotation of 180° counterclockwise about the origin is (0, -5).

Factor the trinomial. You many need to check the discriminant to make sure it can be factored. SHOW YOUR WORK.

lbvjy [14]

Check the discriminant (always a good idea).

b^2 - 4ac
b = -19
c = -15
a = 10

(-19)^2 - 4(10)(-15)
361 + 600
961

Yes it can be factored, but if you like, you could use the quadratic formula.
x = [- (-19) +/- sqrt(961)]/(2 * 10)
x = [19 +/- 31 ] / 20
x = (19 + 31/20
x = (50)/20
x = 5/2

x = [19 - 31] / 20
x = [- 12]/20
x = -3/5

Getting the factors is a little tricky.
(x - 5/2)(x + 3/5) = 0
The first factor is found by putting
x - 5/2 in that form and multiplying through by 2
1/2 (2x - 5) The 1/2 comes from multiplying by 2.

The second factor is
1/5 (5x + 3)

So the equation will look like
1/2(2x - 5)1/5(5x + 3) = 0 If you multiply by 2 you get
(2x - 5)1/5(5x + 3) = 0 and now multiply by 5 you get
(2x - 5) (5x + 3)

Check
2x*5x - 25x + 6x - 15
10x^2 - 19x - 15 = 0

So everything works out.
