Find the slope of the line.
lorasvet [3.4K]
<h3>Given ↓</h3>
  • Two points that a line goes through

<h3>To Find ↓</h3>
  • The line's slope

<h3>Calculations ↓</h3>

When we have two points that a line passes through and asked to determine the slope of the line, the slope formula is going to come in handy.

This is the formula :

\boxed{\\\begin{minipage}{3cm}slope~formula~: \\ $\displaystyle\frac{y2-y1}{x2-x1}$ \\ \end{minipage}}

y2 and y1 are y-coordinates, and x2 and x1 are x coordinates

Plug in the values :

\boxed{\\\begin{minipage}{3cm}$\displaystyle\frac{0-(-7)}{7-0} $\end{minipage}}

\boxed{\\\begin{minipage}{3cm}$\displaystyle\frac{0+7}{7} \end{minipage}}

Which simplifies to ^7/_7, or 1

<h3>Slope ↓</h3>

1 (Option D.)

Can anyone please help me with this ?

Answer:

The distance from point A to the top of the building is 5\sqrt{2} feet

The Height of the Skyscraper is 5 feet

Step-by-step explanation:

Given

Let Top point of building be point C

Also Let Base of the building be point  B

Distance from point A to base B of the building AB= 5 feet

∴ It makes a Right angle triangle

Also ∠ACB = 45°

Also tan 45° = 1

Now tan ∠ACB =\frac{AB}{BC}

∴ AB= BC =5 feet

The Height of the Skyscraper is 5 feet

Now Triangle ABC is right angle triangle with right angled at B

So by Pythagoras theorem

AC= \sqrt{AB^2+BC^2}=\sqrt{5^2+5^2} =\sqrt{50} =\sqrt{25\times2} =\sqrt{5^2\times2}=5\sqrt{2}

The distance from point A to the top of the building is 5\sqrt{2} feet

If 3 = m^x, then we know 9 = (m^x)^2 because 9 is 3 squared.

(m^x)^2 can be simplified to m^{2x}

So now we know 9m^2 = m^{2x}·m^2

Since m^{2x} and m^2 have the same base, we can express it as a single term by adding the exponents together.

So the answer is C) m^{2x+2}
