A line contains the point (4, 5) and is perpendicular to a line with a slope of . Write an equation of the line satisfying the g

KATRIN_1 [288]

Answer:

See example below.

Step-by-step explanation:

This question does not state the slope. But here is an example with the same point (4,5). Perpendicular lines have negative reciprocal slopes. If the slope of one line is -8, its perpendicular line will have the slope of 1/8.

Substitute m = 1/8 and (4, 5) into the point slope form of a line.

$y - y_1 = m(x-x_1)\\y - 5 = \frac{1}{8}(x -4)\\y - 5 = \frac{1}{8}x +\frac{1}{2}\\ y = \frac{1}{8}x \frac{11}{2}$

What is the value of x? enter your answer in the box.

jarptica [38.1K]

To solve this problem, you would have to apply the Pythagorean Theorem: a^2+b^2=c^2

X is the hypotenuse; therefore:

24^2+7^2=x^2

576+49=x^2

625=x^2

To solve this you would have to figure out what the square root of 625 is.

Mr. Litterski creates a ball from rubber bands.

kupik [55]

Answer:

The surface area of the ball is of 29 square inches.

The volume of the ball is of 15 cubic inches.

Step-by-step explanation:

The ball has an spherical format:

Circumference of a sphere:

The circumference of a sphere is 6.2832 times the radius.

Surface area

$A = 4\pi r$

In which r is the radius.

Volume:

$V = \frac{4\pi r^3}{3}$

The circumference of the ball is 9.4 inches.

So the radius is:

$6.2832r = 9.4$

$r = \frac{9.4}{6.2832} = 1.53$

Surface area

$A = 4\pi(1.53)^2 = 29.3$

Rounding to the nearest unit, the surface area of the ball is of 29 square inches.

Volume:

$V = \frac{4\pi (1.53)^3}{3} = 14.9$

Rounding to the nearest unit, the volume of the ball is of 15 cubic inches.

How many yards are in 3 times of 4 yards 2 foot

Len [333]

4 yards and 2 feet is equal 14 feet since each yard is made up of 3 feet.

1 yard = 3 feet.

So if we take 14 feet and multiply that by 3 we get 42 feet.

42/3 is equal to about 14 yards in total

So the answer is 14 yards.
