A kite is 85 feet high with 100 feet of string let out. What is the angle of elevation of the string with the ground? Please sho
a_sh-v [17]

Answer:

  58°

Step-by-step explanation:

A right triangle can be drawn to model the geometry of the problem. The hypotenuse of the triangle is the length of the string, 100 ft. The side opposite the angle is the height of the kite above the ground, 85 ft.

The mnemonic SOH CAH TOA reminds you of the relationship between sides and angles.

  Sin = Opposite/Hypotenuse

  sin(α) = (85 ft)/(100 ft) = 0.85

The angle whose sine is 0.85 is found using the arcsine (inverse sine) function:

  α = arcsin(0.85) ≈ 58.2°

The angle of elevation is about 58°.

_____

When using your calculator to find the values of inverse trig functions, make sure it is in <em>degrees</em> mode. Otherwise, you're likely to get the answer in radians (≈ 1.01599 radians).

Which is an x-intercept of the continuous function in the table?
Airida [17]

we know that

The x-intercept is the value of the variable x when the value of the function is equal to zero

so

In the table we have

(-1, 0) is a x-intercept, because

For x=-1 the value of the function is equal to zero

(-6, 0) is a x-intercept, because

For x=-6 the value of the function is equal to zero

therefore

<u>the answer is</u>

the continuous function in the table has two x-intercepts

(-1, 0)

(-6, 0)

When a = 6 and b = 22, c = 33. If c varies directly with b and inversely with a, which equation models the situation?
deff fn [24]

Answer:

c= 9b/a

Step-by-step explanation:

The statement "y varies directly as x," means that when x increases, y increases by the same factor. The statement "y varies inversely as x means that when x increases, ydecreases by the same factor.

Then, we can say that:

c ∝ b, thus c= kb and c = k/a.

Using both equations we have that:

c= kb/a

Given that a=6, b=22 and c=33 we have that:

33 = 22k/6

Solving for k:

k=9.

Then the equation that models the situation is:

c= 9b/a

f(x) = 3/4 * x - 7 . Find x if f(x) = - 1 . PLEASE tell how to solve it bc that what i dont know, i dont want just the answer​
Eva8 [605]

Answer:

x=-8 if f(x)=-1

Step-by-step explanation:

Given --> f(x)=-\frac{3}{4}x-7

Substitute f(x)=-1 into the equation and solve for x:

-1=-\frac{3}{4}x-7

6=-\frac{3}{4}x

24=-3x

-8=x

So, when f(x)=-1,x=-8
