Answer:

Step-by-step explanation:

If a function has x in the denominator, it cannot be a polynomial.

The rest of the options either don't apply to the equation, or are not rules for polynomials.

John is looking up at the top of the Empire State Building from 1 mi. away and measures the angle of elevation to be 11 degrees.

torisob [31]

Refer to the attached image.

Let the height of the Empire State Building = BC = 'x'

John is standing at distance from Empire State Building = AB = 1 mile

The angle of elevation = 11°

In triangle ABC,

Consider $\tan 11^{\circ}= \frac{Perpendicular}{Base}$

$\tan 11^{\circ}= \frac{BC}{AB}$

$\tan 11^{\circ}= \frac{x}{1}$

$0.194= \frac{x}{1}$

x = 0.194 mile

Since 1 mile =5280 feet

So, x = $0.194 \times 5280$

= 1024.32 feet.

So, the height of the Empire State Building is 1024.32 feet.

Slope intercept form of a line that has a slope of -3/4 and passes through (4, 3)

tia_tia [17]

<h3>Explanation</h3>

First Method

We have the given slope value and the coordinate point that the graph passes through.

$y = mx + b$

where m = slope and b = y-intercept. Substitute the value of slope in the equation.

$y = - \frac{3}{4} x + b$

We have the given coordinate point as well. After we substitute the slope, we substitute the coordinate point value in the equation.

$3 = - \frac{3}{4} (4) + b \\$

Solve the equation for b-term

$3 = - 3 + b \\ 3 + 3 = b \\ 6 = b$

The value of b is 6. We substitute the value of b in the equation.

$y = - \frac{3}{4} x + 6$

Second Method

We can also use the Point-Slope form to solve the question.

$y - y_1 = m(x - x_1)$

Given the y1 and x1 = the coordinate point value.

Substitute the slope and coordinate point value in the point slope form.

$y - 3 = - \frac{3}{4} (x - 4)$

Simplify/Convert into Slope-intercept

$y = - \frac{3}{4} (x - 4) + 3 \\ y = - \frac{3}{4} x + \frac{12}{4} + 3 \\ y = - \frac{3}{4} x + 3 + 3 \\y = - \frac{3}{4} x + 6$

<h3>Answer</h3>

 $\large \boxed {y = - \frac{3}{4} x + 6}$
