Answer:

1. The formula used to the find distance formula is: [tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

2. The distance between the points (-3,8) and (-4, -2) is 10.04

Step-by-step explanation:

1. Which of the following is the correct form of the distance formula?

The formula used to the find distance formula is: [tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

2. Use the distance formula to find the distance between the points (-3.8) and (-4. -?)

Note: Since the y-term in (-4,-) is missing So, I am using -2 to solve the question and find distance. You can use the term given in question and replace it with -2 and use this solution as reference to solve and find the correct answer.

We have points (-3,8) and (-4,-2)

Putting values in distance formula and finding result:

[tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have x_1=-3, y_1=8, x_2=-4, y_2=-2

[tex]Distance=\sqrt{(-2-(-3))^2+(-2-8)^2}\\Distance=\sqrt{(-2+3)^2+(-2-8)^2}\\Distance=\sqrt{(1)^2+(-10)^2}\\Distance=\sqrt{1+100}\\Distance=\sqrt{101}\\Distance=10.04[/tex]

So, the distance between the points (-3,8) and (-4, -2) is 10.04

Answer:

The two triangles are similar by SAS postulate of similarity ⇒ A

Step-by-step explanation:

Let us revise the cases of similarity

In the given figure

∵ There are 2 triangles

∵ The ratio between 2 corresponding sides in the Δs is [tex]\frac{28}{40}[/tex]

∵  [tex]\frac{28}{40}[/tex] = 0.7

∵ The ratio between the other 2 corresponding sides in the Δs is [tex]\frac{42}{60}[/tex]

∵  [tex]\frac{42}{60}[/tex] = 0.7

→ That means 2 sets of corresponding sides have an equal ratio

∴ The 2 sets of corresponding sides are proportional

→ By using the parallel sides

∵ There are two parallel sides

∴ The angles between the sides 28, 42, and the sides 40, 60 equal

   because they are corresponding angles

∴ The included angles are equal in measures

→ By using case 4 above

∴ The two triangles are similar by SAS postulate of similarity

Answer:

-(1/5)

Step-by-step explanation:

The slope is the Rise/Run between the two points (5,-2) and (0,-1):

Rise = -1 - (-2) = 1

Run = 0 - 5 = -5

Slope = Rise/Run = 1/-5 or -(1/5)

Point (0,-1) tells us that the y-intercept, b, is -1, so the full equation is:

 y = -(1/5)x - 1

Answer:

60

Step-by-step explanation:

because 12 inches is one foot so there’s 6 feet per 6 feet of ribbon and there’s 10 of these ribbons so 6 times 10 is 60

The 12-inch pieces the dressmaker can cut from 10 of these rolls of ribbon will be 60 strips .

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is given that the dressmaker has 720 inches of ribbon.

dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length.

The amount of rolls she has =  10 rolls

so,

6(strips per roll) x 10(amount of rolls) = 60 strips

Answer:

5:2

Step-by-step explanation:

Start with what the question is asking for, which is the ratio of math problems to minutes.

With ratios "to" also means ":", so you can change it to math problems : minutes.

Then, substitute the numbers for the labels. Math problems = 10 and minutes = 4, so now you have 10:4

Lastly, to simplify the ratio, find the greatest common factor, in this case 2, and divide both sides, which gives you your answer 5:2

Answer:

From Calculating, the slope would be 0.

Step-by-step explanation:

           This is because of the fact that the two points create a straight line across the x-axis. The points do not have any distance up or down, the only distance is 8 units across. The slope would be 0 because there isn't a slope, only a distance. Hope this helps.

Answer:

a) The distance travelled on the cycle in the first 14 seconds is 96 meters.

b) The acceleration in the first 4 seconds is 2 meters per square second.

Step-by-step explanation:

a) The distance travelled by the cycle is equal to the area below the curve, which is the sum of the first triangle and the rectangle:

[tex]\Delta x = \frac{1}{2}\cdot \left(8\,\frac{m}{s} \right) \cdot (4\,s-0\,s)+\left(8\,\frac{m}{s}\right)\cdot (14\,s-4\,s)[/tex]

[tex]\Delta x = 16\,m +80\,m[/tex]

[tex]\Delta x = 96\,m[/tex]

The distance travelled on the cycle in the first 14 seconds is 96 meters.

b) The acceleration is represented by the slope of the line, which is determined by definition of secant line:

[tex]a = \frac{v(4\,s)-v(0\,s)}{4\,s-0\,s}[/tex] (1)

[tex]a = \frac{8\,\frac{m}{s}-0\,\frac{m}{s}}{4\,s-0\,s}[/tex]

[tex]a =2\,\frac{m}{s^{2}}[/tex]

The acceleration in the first 4 seconds is 2 meters per square second.

Answer:

i - n ii - m

Step-by-step explanation:

Any coordinate on N has a sum of 2, any coordinate on M has a y that is 10 less than the x.

a)

The sum of the coordinates of each point is 2 is line n.

The y-coordinate of each point is 10 less than the x-coordinate is line m.

b)

The labeled points are given above.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

a)

Some of the coordinates of the line m.

= (10, 0), (13, 3), (6, -4)

The y-coordinate of each point is 10 less than the x-coordinate.

Some of the coordinates of the line n.

= (2, 0), (6, -4), (-2, 4)

The sum of the coordinates of each point is 2.

b)

Two points with a sum of 2.

= (2, 0) and (6, -4) on the line m.

Two points where the y-coordinate is 10 less than the x-coordinate.

= (10, 0) and (13, 3) on the number line n.

Two points with a sum of 2 and they-coordinate are 10 less than the

x-coordinate.

= no such points.

Thus,

a)

The sum of the coordinates of each point is 2 is line n.

The y-coordinate of each point is 10 less than the x-coordinate is line m.

b)

The labeled points are given above.

Answer:

41

Step-by-step explanation:

41 degrees is the measure of AngleQ, when the smallest angle in a triangle whose sides have lengths 4, 5, and 6.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Given the side lengths PR = 4, RQ = 6 and PQ = 5

According to the law of cosine,

c=√a²+b²-2abcosФ

Substituting the values,

4=√5²+6²-2×5×6 cos∠Q

4=√25+36-60 cos∠Q

4=√25+36-60 cos∠Q

Take square on both sides

16=25+36-60 cos∠Q

16=61-60 cos∠Q

16-61=-60cos∠Q

-45=-60cos∠Q

Divide both sides by 60

cos⁻¹(45/60)=∠Q

41=∠Q

Hence, the measure of ∠Q is 41 degrees.
