Answer:

Let's find the height:

Half of 8 is 4.

4^2 + 8^2 = 80

80(lets find the square root of 80): 8.944 ^2 = 79.995136 close enough to 80

Your new height is 8.944.

8 x 8.944 = 71.552, 71.552 x 1/2 (basically just dividing by 2) = 35.776 rounded would be = 35.78 cm^2

Formula of area of a triangle:

B(base)H(height) x 1/2(basically just dividing by 2)

In this case 8 is your base and 8.944 is your height.

Explain how to determine it a function is exponential growth or exponential decay. Give an example of each.
kozerog [31]

Answer: Formula is given in the picture Step-by-step explanation: For the exponential growth we have the formula Exponential functions are in the form  y = ab^ xIf  a is positive and b  is greater than  1, then it is exponential growth. If a is positive and b is less than 1 but greater than 0, then it is exponential decay. For Example2 months ago you had 3 mice, you now have 18 shows and exponential growth And Atmospheric pressure (the pressure of air around you) decreases as you go higher shows exponential decay.

How might you prove your observations from question 4 about the length of a midsegment using geometric theorems?
just olya [345]

Answer:To prove the relationship about the length of a midsegment, I can use the properties of parallel lines and transversals. If I draw at least two midsegments, I see that they form congruent triangles within the original triangle, ∆ABC. I can prove the congruence of these triangles using triangle congruence criterion, and then use properties of congruent triangles and the Transitive Property to show that the length of the midsegment is half the length of the side it is parallel to.
