Vladimir [108]2 years ago
4 0

Answer:

c = 18.47

Step-by-step explanation:

This would create a triangle in which the length of the wall would be the missing side. We can use the Pythagorean Theorem to find this:

1. a^{2} + b^{2} = c^{2}

2. 5^{2} + 14^{2} = c^{2}

3. 25 + 196 = c^{2}

4. 221 = c^{2}

5. \sqrt{221} = c

6. 18.47 = c

Kari is flying a kite. She releases 50 feet of string. What is the approximate difference in the height of the kite when the str
MakcuM [25]

Answer:

Step-by-step explanation:

The string of a kite forms a right angle triangle with the ground. The length of the string represents the hypotenuse of the right angle triangle. The height of the kite represents the opposite side of the right angle triangle.

To determine the height of the kite, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse.

1) if the kite makes an angle of 25° with the ground, then the height, h would be

Sin 25 = h/50

h = 50Sin25 = 50 × 0.4226

h = 21.1 feet

2) if the kite makes an angle of 45° with the ground, then the height, h would be

Sin 45 = h/50

h = 50Sin45 = 50 × 0.7071

h = 35.4 feet

The approximate difference in the height of the kite is

35.4 - 21.1 = 14.3 feet

Which graph best represents the function f(x)=2x ?
yan [13]

Answer:

B

Step-by-step explanation:

The best - well, only way- is to check a few points.

Namely -1 (unless your eyesight is really poor!), 0, 1, 2, and 3.

f(x) = 2^x\\f(-1) = 2^-^1 = \frac12\\f(0) =2^0 =1\\f(1)= 2^1=2\\f(2)=2^2=4\\f(3)=2^3= 8

Now you can mark all these points in each graph (well, you could if they were on paper and not on a screen) and see which one of the lines passes through all of them. Spoiler alert, it's the B graph.

A represents 2(2^x) = 2^{x+1}, B is the one you want, C is \frac{2^x}2 = 2^{x-1} and D looks like 4^x = 2^2^x

0.43 (3 repeating) as a fraction
valina [46]

If <em>x</em> = 0.4333…, then

10<em>x</em> = 4.333…

100<em>x</em> = 43.333…

so that

100<em>x</em> - 10<em>x</em> = 43.333… - 4.333…

90<em>x</em> = 39

<em>x</em> = 39/90 = 13/30
