If a kite is 40 feet off the ground and the string holding the kite is 42 feet long, what is the angle of elevation to the kite

1 answer:

3 0

In this case, 40ft is the vertical distance from the ground, which is the height. This means that the kite and the string form an angle with the horizontal ground. A right angled triangle is formed. Use the inverse of sine to get the angle.

Answer:

Part A: 12.5 cm

Part B: 0.8 km

Step-by-step explanation:

Map scale problems can be solved with proportions.

Part A

5 cm / 2 km = x cm / 5 km

5/2 = x/5

2x = 25

x = 12.5

Answer: 12.5 cm

Part B

5 cm / 2 km = 2 cm / x km

5/2 = 2/x

5x = 4

x = 4/5

x = 0.8

Answer: 0.8 km

How is this written in an expanded version?

Yuri [45]

Powers distribute over multiplications:

$(ab)^c = a^c\cdot b^c$

So, you have

$(3k^5)^2 = 3^2 \cdot (k^5)^2$

Now, $3^2$ is simply 9.

As for $(k^5)^2$ , we have to use the rule

$(a^b)^c = a^{bc}$

to get

$(k^5)^2=k^{5\cdot 2}=k^{10}$

So, the final answer is

$(3k^5)^2 =9k^{10}$
