help a girl out What is the slope of a line that would be perpendicular to line k?

Answer:

A

Step-by-step explanation:

Random sampling is a sampling method where each sample has an equal chance of being chosen. The random sample chosen is meant to be an unbiased representation of the population.

If 30% of the sample uses the app, it means that 30% of the population are likely to use the app

Answer:

12%

Step-by-step explanation:

2.79 - 2.49 = $0.30

0.30 / 2.49 = 0.12 = 12% (decimal changes to percent)

You can check your work by doing original cost times the decimal of the percent increase. $2.49 * 0.12 = $0.30. Add this to original -> 0.30 + 2.49 = $2.79.

Step-by-step explanation:

from what i know you do division first so when you do that you get

.83 repeasted add theat to 46 and you ger 45.83 with the three repeated

Answer:

To write 45 as a fraction with a common denominator, multiply by 6/6.

45⋅6/6+5/6=50

Combine 45 and 6/6.

(45⋅6)/6+5/6=50

Combine the numerators over the common denominator.

(45(6+5))/6=50

Simplify the numerator.

275/6=50

Answer:

168 in

Step-by-step explanation:

Pythagoras says:

b² + 56² = 70²

so

b² = 70² - 56²

b = √1764 = 42

so the perimeter is 70+56+42 = 168

Answer:

y= -x/2-1

Step-by-step explanation:

The equation of the line in the slope-intercept form is y=2x−5

The slope of the perpendicular line is negative inverse: m=−1/2

So, the equation of the perpendicular line is y=−x/2+a

To find a, we use the fact that the line should pass through the given point: −4=(−1/2)⋅(6)+a

Thus, a=−1

Therefore, the equation of the line is y=−x/2−1

Answer: y=−x/2−1

That's my best in explaining.

Answer:

factors are 2 and 5.

Step-by-step explanation:

Factors are numbers which you can multiply together to get another number. For Example : The numbers 2 and 3 are factors of 6 because 2 x 3 = 6. A number can have many factors! Example : 2 and 4 are factors of 8, because 4 x 2 = 8. Also 1 and 8 can also be factors of 8, because 1 x 8 = 8.

on prime factorization, we get the factors of 20 as,

2 x 2 x 5 = 20.

Essentially, to factor a negative number, find all of its positive factors, then duplicate them and write a negative sign in front of the duplicates. For instance, the positive factors of −3 are 1 and 3.

-2 x 2 x 5 = -20

2 x 2 x -5 = -20

Answer:

radius=6

Step-by-step explanation:

arc ACB=6xPi

Pi=3.14159

arc ACB=18.85 (rounded to 2 places)

ACB is a half circle so a full circle would be 18.85x2 or 37.7

circumference (whole circle)=2 x Pi x radius

37.7=2 x 3.14159 x radius

radius= 37.7/(2 x 3.14159)

radius=6

Answer:

[tex]y=3(x-2)^2[/tex]

Step-by-step explanation:

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola, and a is a coefficient different from zero.

We are given the vertex located at (2,0). The equation is now:

[tex]y=a(x-2)^2+0[/tex]

[tex]y=a(x-2)^2[/tex]

Since we know the point (1,3) is on the parabola:

[tex]3=a(1-2)^2[/tex]

3=a(1)

a = 3

Finally, the quadratic equation is:

[tex]\mathbf{y=3(x-2)^2}[/tex]
