Answer:

The coordinates of the point are (-4.5,-1).

Step-by-step explanation:

We want to find point T(x,y).

I am going to say that out points are A(-8,-2) and B(6,2)

Since it partitions the segment in a 1:3 ratio, we have that:.

[tex]T - A = \frac{1}{1+3}(B-A)[/tex]

[tex]T - A = \frac{1}{4}(B-A)[/tex]

We apply this to both the x-coordinate and y-coordinate of T.

x-coordinate:

x-coordinate of A: -8

x-coordinate of B: 6

x-coordinate of T: x.

So

[tex]T - A = \frac{1}{4}(B-A)[/tex]

[tex]x - (-8) = \frac{1}{4}(6-(-8))[/tex]

[tex]x + 8 = \frac{14}{4}[/tex]

[tex]x = \frac{14}{4} - 8[/tex]

[tex]x = \frac{14}{4} - \frac{32}{4}[/tex]

[tex]x = -\frac{18}{4}[/tex]

[tex]x = -4.5[/tex]

y-coordinate:

y-coordinate of A: -2

y-coordinate of B: 2

y-coordinate of T: y.

[tex]T - A = \frac{1}{4}(B-A)[/tex]

[tex]y - (-2) = \frac{1}{4}(2-(-2))[/tex]

[tex]y + 2 = 1[/tex]

[tex]y = -1[/tex]

The coordinates of the point are (-4.5,-1).

Answer:

2.8

Step-by-step explanation:

The tenths place is one place to the right of the decimal place.

Since 1 is less than 5, you keep 8 in the tenths place.

Answer:

  110 square inches

Step-by-step explanation:

First, recall the formula for the area of a trapezoid:

  A = (1/2)(b1 +b2)h

Next, identify the base and height dimensions on the figure.

  b1 = 13 in; b2 = 9 in; h = 10 in

Next, fill the numbers into the formula and do the arithmetic.

  A = (1/2)(13 in + 9 in)(10 in) = (1/2)(22 in)(10 in) = 110 in^2

Last, answer the question asked.

  The area of the trapezoid is 110 square inches.

The slope is equal to the change in y / change in x.

The change in y is always 5 and the change in x is always 1.

So the change in y / change in x is 5/1 or 5.

The y-intercept is the value of y when x = 0.

So the value of y when x = 0 is 2.

Answer:

9.9 m

Step-by-step explanation:

According to the scale the person is 2 cm tall, and the tree is 12 cm tall.

So we know that the tree is 6 times taller than the person because,

12 cm = 6 x 2 cm

The actual height of the person is 1.65 m.

Since we know that the tree is 6 times taller than the person, we can find the height of the tree to be

6 x 1.65 m = 9.9 m

Step-by-step explanation:

Given: A right circular cylinder is to be designed to hold 22 cubic inches of soft drink.

To find: equation in [tex]r[/tex] and [tex]h[/tex]

Solution:

Let [tex]r[/tex] denotes radius of a cylinder and [tex]h[/tex] denotes height of a cylinder.

Volume of a cylinder [tex]=22[/tex] cubic inches

Also,

Volume of a cylinder [tex]=\pi r^2h[/tex]

Answer:

2^7 ≠ 7^2

Step-by-step explanation:

2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2

The only factor is 2

7^2 = 7 * 7

The only factor is 7

Comparing the factors when written as a repeated multiplication,

2^7 and 7^2 have no common factor :

2^7 = 2 * 2 * 2 * 2 * 2 * 2 * 2 = 128

7^2 = 7 * 7 = 49

Answer:

The midpoint is (3, 3).

Step-by-step explanation:

We are given the two points A(9, 11) and B(-3, -5).

The midpoint is given by:

[tex]\displaystyle M=\Big(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\Big)[/tex]

So:

[tex]\displaystyle M = \Big( \frac{9+(-3) }{2}, \frac{ 11+(-5) }{2} \Big) = (3,3)[/tex]

The midpoint is (3, 3).

We want to show that AM = MB.

We can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

The distance between A(9, 11) and M(3, 3) will then be:

[tex]AM=\sqrt{(9-3)^2+(11-3)^2}=\sqrt{6^2+8^2}=\sqrt{100}=10[/tex]

And the distance between B(-3, -5) and M(3, 3) will be:

[tex]MB = \sqrt{ (3-(-3))^2 + (3-(-5))^2 } = \sqrt{(6)^2+(8)^2} = \sqrt{ 100 } = 10[/tex]

So, AM = MB = 10.

Since AM = MB = 10, AM + MB = 10 + 10 = 20.

So, we want to prove that AB = 20.

By the distance formula:

[tex]AB=\sqrt{(9-(-3))^2+(11-(-5))^2}=\sqrt{12^2+16^2}}=\sqrt{400}=20\stackrel{\checkmark}{=}20[/tex]
