what is the slope of the line that passes through the points (-9,10) and (-13,13)

Answers

Answer:

-3/4

Step-by-step explanation:

The slope of line passes through the points (-9,10) and (-13,13) is -3/4.

what is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

(-9,10) and (-13,13)

So, slope= (13 - 10)/ ( -13 + 9)

slope= 3 / (-4)

slope= -3/4

Hence, the slope of line is -3/4.

One angle of a parallelogram measures 162°. What are the measures of the other three angles in the parallelogram?

Answers

Answer:

The important properties of parallelograms to know are:

-Opposite sides of parallelogram are equal (AB = DC).

-Opposite angles of parallelogram are equal (D = B).

-Consecutive angles in a parallelogram are supplementary (A + D = 180°).

-If one angle is 90 degrees, then all other angles are also 90 degrees.

FROM

SURAJ SAINI

Answer:

162,162,18,18

Step-by-step explanation:

each two opposite angles are equal

since there is an angle equals 162° then the opposite angle equals 162°

since the sum of all angles equal 360°

360-(162+162)= 36

so the sum of the other two opposite angle = 36 then the measure of one angle =36/2 =18°

the radius of a circle is 7 cm .the circle is divided into two equal parts .what is the perimeter of the semi circular part

Answers

Answer:

P = 35.98 cm

Step-by-step explanation:

The Perimeter of a shape is the distance around the outside of it. This semi-circle (half circle) has a straight part and the curved part. See image. The straight part is the diameter (distance through the center) it is double the radius that was given, 7 cm.

The circumference of a circle is the perimeter of the whole circle.

C = 2pi•r or pi•d

C = 2pi•7 = 14pi

But you only need half, so 14pi/2 is 7pi.

ADD the straight part and the curved part to get the whole distance around the shape

P = 14 + 7pi

P ~= 35.98 cm

Lily threw a ball. The balls equation that demonstrated its height and velocity is:
h(x) = -16x2 + 3x + 35
What was the initial height that she threw the ball from?

Answers

The initial height of the ball is the y-intercept of the function

The initial height she threw the ball from is 35

How to determine the initial height

The function is given as:

[tex]h(x) = -16x^2 + 3x +35[/tex]

Set x = 0.

So, we have:

[tex]h(0) = -16 * 0^2 + 3*0 +35[/tex]

Evaluate the exponent

[tex]h(0) = -16 * 0 + 3 * 0 + 35[/tex]

Evaluate the products

[tex]h(0) = 0 + 0 + 35[/tex]

Evaluate the sum

[tex]h(0)= 35[/tex]

Hence, the initial height she threw the ball from is 35

What is the actual length of the swing set area of the park?

Enter your answer in the box.

The actual length of the swing set area of the park is [blank]

feet.

Answers

Answer:

The dimensions of the park on the scale drawing are 12 inches by 20 inches

The actual dimensions are given as:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

The dimension of the swing set on the scale drawing is given as: 0.5 inch by 2 inches

The above means that, the scale factor (k) is:

--- i.e. divide the scale measurement by the actual measurement

Evaluate both equations

So, we have:

Multiply the scale factor by the dimensions of the park, to get the scale measurement

Hence, the dimensions of the park on the scale drawing are 12 inches by 20 inches

Researchers estimate that 21.5% of men and 17% of women smoke cigarettes.1
The rate of new cases in 2008 showed that men develop lung cancer more often than women (70.2 and 50.5 cases per 100,000 persons, respectively).2
Smoking, a main cause of small cell and non-small cell lung cancer, correlates to 90% and 80% of lung cancer deaths in men and women, respectively.3 That is, 90% of men who are diagnosed with lung cancer are active smokers, and 80% of women who are diagnosed with lung cancer are active smokers.

My little brother spent $53 on comic books and magazines. He bought 17 items. If comic books cost $4 and magazines cost $3, how many of each item did my brother buy?

Answers

Answer:

comic books = 2

magazines = 15

Step-by-step explanation:

Let c = number of comic books bought

Let m = number of magazines bought

He bought 17 items, so

c + m = 17

Comic books cost $4 each and magazines cost $3 each.

He spent $53 on comic books and magazines, so

4c + 3m = 53

Rearrange c + m = 17 to make m the subject:

m = 17 - c

Substitute m = 17 - c into 4c + 3m = 53 and solve for c:

4c + 3(17 - c) = 53

⇒ 4c + 51 - 3c = 53

⇒ c = 2

Substitute c = 2 into m = 17 - c to and solve for m:

m = 17 - 2 = 15

Write the point slope form of the equation of the line through the given point and slope

Answers

Step-by-step explanation:

the point-slope form in general is

y - y1 = m(x - x1)

where (x1, y1) are the coordinates of a point, and m is the slope.

so, we have

y - -1 = 4/3 × (x - 3)

or simplified

y + 1 = 4/3 × (x - 3)

Answer:

[tex]y + 1 =\frac{4}{3} (x-3)[/tex]

Step-by-step explanation:

Pre-Solving

We are given that a line contains the point (3, -1), and has a slope of [tex]\frac{4}{3}[/tex].

We want to write the equation of this line in point-slope form.

Point-slope form is given as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1 ,y_1)[/tex] is a point.

Solving

Since we are already given the slope and the point of the line, we can plug these values into the formula to get the equation.

Let's start with the slope; replace m with [tex]\frac{4}{3}[/tex] in the formula.

[tex]y-y_1=\frac{4}{3}(x-x_1)[/tex]

Now, replace 3 as [tex]x_1[/tex] and -1 as [tex]y_1[/tex]. Remember that the formula has subtraction in it.

[tex]y--1=\frac{4}{3} (x-3)[/tex]

This can be simplified to become:

[tex]y + 1 =\frac{4}{3} (x-3)[/tex]
