Answer:

13064 feet

Step-by-step explanation:

We can rewrite the formula so that x is in feet. Equating the new formula to 8.743 PSI, we have ...

8.743 = 14.7e^(-0.21x/5280)

Dividing by 14.7 and taking natural logs, we have ...

ln(8.743/14.7) = -0.21x/5280

Multiplying by the inverse of the coefficient of x gives ...

x = 5280·ln(8.743/14.7)/-0.21 ≈ 13064.0806

The peak of the mountain is about 13,064 feet high.

Answer: OPTION B

Step-by-step explanation:

You can observe in the graph of the function given, it begins to decrease from --3π/2 to -π/2. Then it increases again to y=3, where it reaches it maximum point, this is when x=kπ/2 (With k an odd integer: 1,3,5,7...)

Finally, it begins to decrease again from π/2 to 3π/2.

Therefore, the answer is the option B.

Round to the nearest tenth

Note: I am assuming we have to determine the value of the side 'x'.

Answer:

The value of x = 8.1 units

Step-by-step explanation:

Note: I am assuming we have to determine the value of the side 'x'.

Given

Angle Ф = 32°

To determine:

x = ?

Using the trigonometric ratio

tan Ф = opposite / adjacent

here

Ф = 32°

opposite to angle 32° = x

adjacent to angle 32° = 13

Therefore,

substituting adjacent = 13, Ф = 32°, opposite = x in the equation

tan Ф = opposite / adjacent

$\tan \left(32^{\circ \:}\right)=\frac{x}{13}$

$\:x\:=\:13\:\times tan\:32^{\circ }\:$

x = 8.1 units tan 32° = 0.62

Therefore, the value of x = 8.1 units
