Please help with number 1
bezimeni [28]

Answer:

19.0681

Step-by-step explanation:

Given in the question that,

angle from ted to the dog = 60° with the ground

height of ted from the ground =  16ft

To find,

distance between dog and the door of ted's building

Considering the scenario make a right angle triangle:

<h3>By using pythagorus theorem:</h3>

Tan 40 = opposite / adjacent

Tan 40 = height / distance between dog and the door

Tan 40 = 16ft / x

x = 16 / tan40

x = 19.068057

x ≈ 19.0681 (nearest to thousand)

So, the dog need to walk 19.0681ft to reach the open door directly below Ted.

What is a equation of the line that passes through the point (−5,7) and is parallel to the line x+5y=10
dsp73

Answer:

\displaystyle y = -\frac{1}{5} x +6

Step-by-step explanation:

<u>Equation of a LIne</u>

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Where m is the slope and (h,k) is a point through which the line passes.

We are required to find the equation of a line that passes through the point (-5,7) and is parallel to the line x+5y=10.

This information provides us the values of h=-5 and k=7. We now need to determine the value of the slope.

Two parallel lines have equal values for the slopes. The equation of the line

x + 5y = 10

Can be rearranged in such a way we can find its slope. Let's solve it for y:

5y = -x + 10

y = -\frac{1}{5}+2

The slope of this line is -1/5 and that is the same value of the slope of our line, thus its equation is:

\displaystyle y - 7 = -\frac{1}{5} ( x + 5 )

Adding 7:

\displaystyle y = -\frac{1}{5} ( x + 5 )+7

Operating:

\displaystyle y = -\frac{1}{5} x + -\frac{1}{5}*5 +7

\displaystyle y = -\frac{1}{5} x -1+7

\boxed{\displaystyle y = -\frac{1}{5} x +6}
