Answer:

Step-by-step explanation:

As we can see, this triangle has 2 equal sides in length, which makes it an isosceles triangle. As the Base Angles Theorem states, the base angles of an isosceles triangle are congruent. In this case, angles a and b are the base angles. We now know they are both congruent, so we'll mark them both as a. Next, we notice that the measure of the other angle is 122°. We also know that the sum of all of the angle measures in a triangle is 180°. Using algebra and what we know so far, we can write this equation:

122°+a+a=180°.

When we solve for a, we get:

122°+2a=180° (add a and a)

2a=58° (subtract 122 from both sides)

a=29°

Since we know a=b, b=29°.

The function h(t) = -4.9t² + 19.6t is used to model the height of an object projected in the air where h(t) is the height (in me

goblinko [34]

Answer:

Step-by-step explanation:

when h(t)=0

-4.9 t²+19.6t=0

4.9t(-t+4)=0

either t=0 or t=4

so domain is 0≤t≤4

for range

h(t)=-4.9t²+19.6t

=-4.9(t²-4t+4-4)

=-4.9(t-2)²+19.6

so range is 0≤h≤19.6

Find the perimeter of triangle PQR. Round your answer to the nearest tenth.

BabaBlast [244]

We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.

Side PQ = $\sqrt{ (6-(-2))^{2}+ (1-1)^{2} }=8$

Side QR = $\sqrt{ (4-6)^{2}+ (-3-1)^{2} }=4.5$

Side RP = $\sqrt{ (2-(-4))^{2}+ (-3-1)^{2} }=7.2$

So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7

You probably misplaced the digits in option A. The correct answer is 19.7 units.

500x+38000

500(22)+38000

11000+38000

49000

Step-by-step explanation:

We can write the following equation

38000+500x= salary

where x is the number of air conditioners sold

To get the answer just plug in 22 for x

38000+500(22)=49000

Find the greatest power of 3 that is divisible of 100!

Vitek1552 [10]

Answer:

There is no greatest power of 3 that is divisible of 100.

Step-by-step explanation:

Since any number can always be divisible of 100, there would be no greatest power of 3 that is divisible of 100 since the powers can go on and on forever without stopping, and all powers of 3 is able to be divided by 100.
