Line L passes through the points (1, 1) and (7, 8). What is the slope of a line that is perpendicular to line L?

asambeis [7]

When a line passes through the two points $(x_{1},y_{1}) and (x_{2},y_{2})$ , its slope is given by the formula $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this question, a line L passes through the points $(1,1) and (7,8)$

So, its slope is given by $m=\frac{8-1}{7-1}$

$m=\frac{7}{6}$

When two lines are perpendicular, then the product of their slopes is -1.

Since, the slope of the line L is $\frac{7}{6}$ , so the slope of the line which is perpendicular to the given line L is $\frac{-6}{7}$ as the product of $\frac{-6}{7} \times \frac{7}{6}=-1$ .

Find b in triangle TRG. Please help, I'm not sure how to solve for b.

Marina CMI [18]

Answer:

b=4.9

C. is the correct option.

Step-by-step explanation:

In triangle TGN,

Let <RTG be x

cosx= b/h

or, cosx = 2/a

Again,

In triangle TRG,

cosx = b/h

(for bigger right angled triangle)

cosx = a/(4+2)

cosx = a/6

Now

cosx = 2/a = a/6

or, 2/a = a/6

or, 12 = a²

so, a² = 12

Now,

For TRG,

h² = p²+b²

or, 6² = b² + a²(a²=12)

or, 6² = b² + 12

or, 36 = b² + 12

or, 36 -12 = b²

or, b² = 24

or, b = square root 24

so, b = 4.8989

so, b = 4.9

The legend on a map states that 1

Firdavs [7]

Answer:

$Actual = 480\ miles$

Step-by-step explanation:

Given

$Map : Actual = 1\ in: 80\ miles$

Required

Find actual distance when map distance = 6 inches

Substitute 6 for Map in $Map : Actual = 1\ in: 80\ miles$

$6\ in: Actual = 1\ in: 80\ miles$

Express as fractions

$\frac{6\ in}{Actual} = \frac{1\ in}{80\ miles}$

$\frac{6}{Actual} = \frac{1}{80\ miles}$

Cross Multiply

$Actual * 1 = 6 * 80\ miles$

$Actual = 6 * 80\ miles$

$Actual = 480\ miles$

<em>Hence, the actual distance is 480 miles</em>
