The answer is choice D

-----------------------------------------

Explanation:

We can rule out choice B and choice C which are y = 2.4^x and y = 3.5^x respectively. Why can we eliminate these? Because they are growth functions (the bases are larger than 1). The graph shown is a decay function. It goes downhill as you read it from left to right.

The answer is either choice A or choice D

If we plug in x = -2 into the equations for A and D, we get
y = 0.65^x = 0.65^(-2) = 2.36686
y = 0.32^x = 0.32^(-2) = 9.765625

The result for choice D is much closer to what the graph is showing. The graph appears to have the point (-2,11) on the curve. So that's why choice D is the best answer. 

Note: the graph is a bit small and its not entirely clear which points are on this graph other than (0,1). So this is a bit of educated guesswork.

I would say it is <span>D- (-4,-5), for counterclockwise you turn towards the right. At 180 degrees it would be (4, -5) if you turn again you would get (-4,-5) hope this helps</span>

How is the graph of y=3(x+1)^2 related to its parent function y=x^2
creativ13 [48]
The parent function is y = x^2

There is a compression of 3:

y = 3x^2

There is a shift by 1 unit to the left:

y = 3(x + 1)^2

Hello! can you please, help me by finding some missing angles.
yuradex [85]

Answer:

Going horizontally,

Q1 a) x = 133°

Q1 b) x = 59°

Q1 c) x = 189°

Q1 d) x = 32°

Q1 e) x = 72°

Q1 f) x = 36°

Q2 a) x = 53°

Q2 b) x = 94°

Q2 c) x = 10°

Workings out:

To work out the interior angles, you need to know that angles on a straight line add up to 180°. In addition, you also need to know that angles around a point add up to 360°. When you need to find a missing angle, if the angle is on a line or in a triangle, take whatever value/values the angle/angles you have are and take it away from 180°. If the angle is around a point, (or in a square, where all angles are the same anyway) add however many values you have for the angles then take that away from 360°. Hope this helps! :)

Answer:

64 ft²

Step-by-step explanation:

10 ft · 10 ft

100 ft²

A=\frac{bh}{2}

6 · 6 = 36

36 ÷ 2 = 18

18 ft² + 18 ft² = 36 ft²

100 ft² - 36 ft²

64 ft²
