Answer:

5.2 ft

Step-by-step explanation:

\cos 30 \degree =  \frac{6}{length \: of \: platform}  \\  \\  \frac{ \sqrt{3} }{2} =  \frac{6}{length \: of \: platform}  \\  \\ length \: of \: platform  = \frac{2 \times 6}{ \sqrt{3} }  \\  \\ length \: of \: platform  = \frac{12\sqrt{3} }{ 3}  \\  \\ length \: of \: platform  =4 \sqrt{3}  \\  \\ length \: of \: platform  =4 \times 1.732 \\  \\  length \: of \: platform = 5.228 \\  \\ length \: of \: platform  = 5.2 \: ft

Answer:

Question 1: Answer would be A.

Question 2: Answer would be B.

Question 3: I cannot answer this one because an image is not provided. I do not have the image of the original triangle LMN. If you message me with a photo of this question, I will be able to answer.

Question 4: This answer may be wrong, but I believe that it would be A. I don't know how to calculate dilation transformations, but after graphing out all the points, I found that (6,4) would be the correct point because the distance between Point S and (6,4) is even and is able to be divided by two.

Question 5: Again, I cannot answer this one because an image is provided. Message me with a photo, I'll answer.

Question 6: Answer would be C.

Question 7: Again, I cannot answer this one because an image is provided. Message me with a photo, I'll answer.

Question 8: Answer would be C.

Step-by-step explanation:

Question 1 Explanation: Answer would be A because the quadrilateral was rotated 180 degrees and dilated to be larger.

Question 2 Explanation: Quadrant IV is on the bottom right, Quadrant I is on the top right. If a triangle were to be rotated from the origin (0,0), it would have to rotate 270 degrees in order to reach Quadrant I.

Question 3 Explanation:

Question 4 Explanation:

Question 5 Explanation:

Question 6 Explanation: Using a rotation calculator, I input the degree of rotation as -90.

Question 7 Explanation:

Question 8 Explanation: Using a rotation calculator, I input the degree of rotation as -180.

Sara has $150 in her savings account. The amount in her account increases by %6 every year. If she does not put more money into
strojnjashka [21]

Answer:

$159

Step-by-step explanation:

we know that

The equation of a exponential growth function is equal to

y=a(1+r)^x

where

y is the balance in the saving account

x is the number of years

a is the initial amount

r is the percent rate of change

we have

a=\$150\\r=6\%=6/100=0.06

substitute

y=150(1+0.06)^x

y=150(1.06)^x

For x= 1 year

substitute

y=150(1.06)^1=\$159
