Answer:

F. Obtuse isosceles

Step-by-step explanation:

Since we have an angle that is 100 degrees, we have an obtuse angle

We have two angles that are 40, which means we have two sides that are equal length, because two angles have the same measure. That means it is isosceles

The triangle is an obtuse isosceles

Answer:

Perimeter = 21 units

Volume = 110 cubic units

Step-by-step explanation:

Let the center of circle be (x,y).

$(x+2)^{2} +(y-7)^{2} = (x)^{2}+(y+2)^{2}$

4x - 18y = - 45

$(x)^{2}+(y+2)^{2}=(x-2)^{2}+(y-2)^{2}$

4x + 8y = 4

x + 2y = 1

Solving these 2 equations,

4 - 26y = -45

y = $\frac{49}{26}$

x = $\frac{-36}{13}$

radius = 3.35

Perimeter = 2 $\pi r$ = 21 units

Volume of cylinder = $\pi r^{2} h$

We have to add the volumes of the cylinders.

Volume of smaller cylinder = $\pi \times 2^{2} \times 2$ = 8 $\pi$

Volume of larger cylinder = 27 $\pi$

Total volume = 35 $\pi$ = 110 cubic feet

Will give brainliest.

Leno4ka [110]

Part A: y-intercept = 12 miles

Part B: Find the average rate of change: 36 - 20/2 = 16/2 = 8 mph
This tells us that the bird can travel long distances.

Part C: 172 - 12 = 160 miles at a rate of 8 mph
160 mi ÷ 8mph = 20 hrs

Domain of function = 0 ≤ x ≤ 20

What is the numerator of the fraction equivalent to 3\5 that has a denominator of 30

aliya0001 [1]

Well, the numerator is the number on top, so in the fraction 3/5, 3 is the numerator. To find the equation with a denominator of 30 that is equivalent, find what the difference is. 30/5 = 6. So now, multiply the numerator by 6. 6 * 3 = 18. The new fraction is 18/30. The numerator is 18. Hope this helps!
