Answer:

33.6 feet

Step-by-step explanation:

Given : An ant looks up to the top of a tree with an angle of elevation of 38.

To Find:  If the ant is 43 feet from the base of the tree, what is the height of the tree, to the nearest tenth?

Solution:

Refer the attached figure

An ant looks up to the top of a tree with an angle of elevation of 38.i.e.∠ACB= 38°

The ant is 43 feet from the base of the tree i.e.BC = 43 feet.

Now we are supposed to find the height of the tree i.e. AB

Now we will use trigonometric ratio

Tan \theta = \frac{Perpendicular}{Base}

Tan 38^{\circ} = \frac{AB}{BC}

Tan 38^{\circ} = \frac{AB}{43}

0.78128= \frac{AB}{43}

0.78128 \times 43= AB

33.6= AB

Hence the height of the tree is 33.6 feet.

Wut is the value of m?<br><br> 7m=90
Sedbober [7]
The value of m is 12 6/7.

Explanation:
To find m, we want one m instead of 7, so we divide both sides by 7. 7m/7 = 90/7, which would be m = 12 6/7.

Find f(1/4)<br><br> if f(x)=4x^2-2/3x<br><br>please guys explain it to me I cant understand it ​
Jet001 [13]

Answer:

f(1/4) = 1/12

Step-by-step explanation:

f(x) = 4x^2 - 2/3 x is a function. The name of the function is simply the letter f. It tells you a rule. f(x) is the same as y.

It is the same as having

y = 4x^2 - 2/3 x

For each value of x you are given, you can calculate a corresponding value of y. Instead of calling y, y, we call y "f(x)" which is a way of showing that this relation is a function.

If you were given

y = 4x^2 - 2/3 x and were asked to find the value of y when x = 1/4, what would you do?

You would substitute 1/4 for x in the expression 4x^2 - 2/3 x, and you'd find the value of y.

Being asked to find f(1/4) for function f(x) = 4x^2 - 2/3 x means exactly the same. It means what is the value of the function when x = 1/4? What is the y value corresponding to an x value of 1/4?

Let's calculate it:

f(x) = 4x^2 - 2/3 x

To show we are evaluating the function at an x value of 1/4, we use the notation f(1/4). f(1/4) means find the value of y for function f when x = 1/4. We replace x with 1/4 and do the math.

f(1/4) = 4(1/4)^2 - (2/3)(1/4)

f(1/4) = 4(1/16) - 2/12

f(1/4) = 4/16 - 2/12

f(1/4) = 1/4 - 2/12

f(1/4) = 3/12 - 2/12

f(1/4) = 1/12

(fx+cd)/(x-f)=1/2 solve for x
sesenic [268]

Answer:

Step-by-step explanation:

(fx+cd)/(x-f)=1/2

Cross multiplication,

2*(fx + cd) = 1 * (x-f)

2fx + 2cd = x - f

2fx - x  = -2cd - f

x (2f - 1) = -2cd -f

x = (-2cd-f )/ (2f-1)
