Determine whether this pair of lines is parellel, perpendicular, or neither 6+2x=3y 3x+2y=9 Choose the correct answer below. A.
andriy [413]

Answer:

Option A. These two lines are perpendicular

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are equal

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

step 1

Convert the given equation A in slope intercept form

y=mx+b

where

m is the slope

b is the y-intercept

we have

6+2x=3y ----> equation A

Solve for y

That means----> isolate the variable y

Divide by 3 both sides

y=\frac{2}{3}x+2

so

m_A=\frac{2}{3}

step 2

Convert the given equation B in slope intercept form

y=mx+b

where

m is the slope

b is the y-intercept

we have

3x+2y=9 ----> equation B

Solve for y

That means----> isolate the variable y

subtract 3x both sides

2y=-3x+9

Divide by 2 both sides

y=-\frac{3}{2}x+4.6

so

m_B=-\frac{3}{2}

step 3

Compare the slopes

m_A=\frac{2}{3}

m_B=-\frac{3}{2}

The slopes are opposite reciprocal (the product is equal to -1)

therefore

These two lines are perpendicular

Which shows the expression below in simplified form? (2.4 × 1018) + (3.4 × 1015)
RUDIKE [14]

Answer: 5894.2

Step-by-step explanation:

You'll want to follow PEMDAS to simplify this expression.

1.) P - Parentheses

2.) E - Exponents

3.) M - Multiplication

4.) D - Division

5.) A - Addition

6.) S - Subtraction

We'll start with what's inside the parentheses:

(2.4 × 1018) + (3.4 × 1015)

(2,443.2) + (3,451)

Now all you have to do is add the values together to get your answer!

2,443.2 + 3,451

5894.2

Sam ran 63,756 feet in 70 minutes. What is Sam's rate in miles per hour? ( there are 5,280 feet in one mile.)
umka21 [38]
Simply convert first feets into miles
Given is 5280 feets=1 miles

63756 /5280=12.075 miles

70 minutes  = 1.16666= 1.17 hrs

rate is 12.075 miles/1.17 hrs

A cell tower has the hieght of 70 meters. The Tower casts a shadow of 45 meters on the ground. What is the angle of elevation of
laiz [17]

Answer:

\theta=0.99^{\circ}

Step-by-step explanation:

Given that,

The height of a cell tower, P = 70 m

The tower casts a shadow of 45 meters on the ground.

We need to find the angle of elevation of the shadow to the top of the cell tower. We can use trigonometry to find it.

\tan\theta=\dfrac{P}{B}

Put all the values,

\tan\theta=\dfrac{70}{45}\\\\\theta=\tan^{-1}\left(\frac{70}{45}\right)\\\\\theta=0.99^{\circ}

Hence, the angle of elevation is equal to 0.99^{\circ}.
