A man flies a kite at a height of 16 ft. The wind is carrying the kite horizontally from the man at a rate of 5 ft./s. How fast

Talja [164]

Answer:

4.41 feet per second.

Step-by-step explanation:

Please find the attachment.

We have been given that a man flies a kite at a height of 16 ft. The wind is carrying the kite horizontally from the man at a rate of 5 ft./s. We are asked to find how fast must he let out the string when the kite is flying on 34 ft. of string.

We will use Pythagoras theorem to solve for the length of side x as:

$x^2+16^2=34^2$

$x^2=34^2-16^2$

$x^2=900\\\\x=30$

Now, we will use Pythagorean theorem to relate x and y because we know that the vertical side (16) is always constant.

$x^2+16^2=y^2$

Let us find derivative of our equation with respect to time (t) using power rule and chain rule as:

$2x\cdot \frac{dx}{dt}+0=2y\cdot \frac{dy}{dt}$

We have been given that $\frac{dx}{dt}=5$ , $y=34$ and $x=30$ .

$2(30)\cdot 5=2(34)\cdot \frac{dy}{dt}$

$300=68\cdot \frac{dy}{dt}$

$\frac{dy}{dt}=\frac{300}{68}$

$\frac{dy}{dt}=4.4117647058823529$

$\frac{dy}{dt}\approx 4.41$

Therefore, the man must let out the string at a rate of 4.41 feet per second.

The scale on a map shows 1 cm = 5 km. On this same map, the distance between Clarkstown and Millburn is 3.5 cm. What is the actu

Ugo [173]

Answer:

15.10 km

Step-by-step explanation:

All you would have to do is add 5 km every time you add 1 cm. Then for the .5 you would divide 5 by .5 to get the second part of the answer.

Hope this helps!

I got it wrong I'm sorry!

Answer:

15. a, 16. ∠GOH = 26

Step-by-step explanation:

15. A straight angle looks as a line.

16. ∠GOI = ∠GOH + ∠HOI

47 = ∠GOH + 21

∠GOH = 47 - 21 =26

∠GOH = 26

Answer:

The three consecutive odd integers are: -1, 1, 3

Step-by-step explanation:

The three consecutive odd integers be x, x + 2, x + 4

Now according to the question

It is mentioned that

The four times the middle integer is two lower than tfhe sum of the first and third

i.e.

4(x+2) = [x + (x+4)] + 2

4x + 8 = 2x + 6

2x = -2

x = -1

Hence, The three consecutive odd integers are: -1, 1, 3
