If 3 to the power of k+3 minus 3 to the power of k equals m, what is 3 to the power of k+2 in terms of m?
Sergeu [11.5K]

Answer:

3^(k+2) = 9m/ 26

Step-by-step explanation:

Let 3^k = y :

y×3^3-y = m

26y = m

26×3^k = m

3^(k+2) = m/26×3^2

Therefore 3^(k+2) = 9m/26

1. A slide 3.5 m long makes an angle of 28° with
balu736 [363]

Answer: Option d.

Step-by-step explanation:

Draw a right triangle using the data given in the exercise (Observe the picture attached)

Let be "h" the height in meters from the ground to the top of the slide.

You need to use the following Trigonometric Identity:

sin\alpha =\frac{opposite}{hypotenuse}

In this case you can identify that:

\alpha =28\°\\oppossite=h\\hypotenuse=3.5

Therefore, susbstituting values into sin\alpha =\frac{opposite}{hypotenuse} and solving for "h", you get:

sin(28\°) =\frac{h}{3.5}\\\\(3.5)(sin(28\°))=h\\\\h=1.64
