Find the value of x. Round to the nearest tenth.

Mathematics
1 answer:
lawyer [7]2 years ago
7 0

Answer/Step-by-step explanation:

Apply trigonometric bratio formula where applicable, to find the value of x in each case. Recall the acronym, SOHCAHTOA. This will help toe ash determine which ratio formula to use depending on the information given.

4. \theta = 33

Opp = x

Hyp = 14

Therefore, apply SOH. Which is,

sin(33) = \frac{x}{14}

Multiply both sides by 14

sin(33)*14 = x

7.6 = x (nearest tenth)

5. \theta = 29

Adj = x

Hyp = 14

Therefore, apply CAH. Which is,

cos(37) = \frac{x}{14}

Multiply both sides by 14

cos(37)*14 = x

11.2 = x (nearest tenth)

6. \theta = 29

Opp = x

Adj = 5.4

Therefore, apply TOA. Which is,

tan(29) = \frac{x}{5.4}

Multiply both sides by 5.4

tan(29)*5.4 = x

3.0 = x (nearest tenth)

7. \theta = 55

Opp = x

Adj = 33

Therefore, apply TOA. Which is,

tan(55) = \frac{x}{33}

Multiply both sides by 33

tan(55)*33 = x

47.1 = x (nearest tenth)

Evaluate the function f(x) at the given numbers (correct to six decimal places).
statuscvo [17]

Answer:

The values of given function are shown in the below table.

Step-by-step explanation:

The given function is

f(x)=\frac{x^2-5x}{x^2-x-20}

Simplify the given function.

f(x)=\frac{x(x-5)}{x^2-5x+4x-20}

f(x)=\frac{x(x-5)}{x(x-5)+4(x-5)}

f(x)=\frac{x(x-5)}{(x+4)(x-5)}

Cancel out the common factor.

f(x)=\frac{x}{x+4}

Substitute x=5.5 in the above equation.

f(5.5)=\frac{5.5}{5.5+4}

f(5.5)=\frac{5.5}{9.5}

f(5.5)=0.57894736842

f(5.5)\approx 0.578947

Similarly find the value for all values of x.

The values of given function are shown in the below table.

An observation deck extends 202 feet out above the valley. The deck sits 152 feet above the valley floor. If an object is droppe
OleMash [197]

Answer:

<h3>3 secs</h3>

Step-by-step explanation:

Given the height of the object as it drops from the observation deck expressed as;

h= -16t^2+152

To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;

8 = -16t^2+152

subtract 8 from both sides

8-8 = -16t^2+152-8

0 =  -16t^2+144

0-144 =  -16t^2

-144 = -16t^2

16t^2 = 144

Divide both sides by 16;

16t^2/16 = 144/16

t^2 = 9

t = √9

t = 3seconds

Hence it will take 3 seconds for the object to be 8 feet above the valley floor
