B is the midpoint of AC and E is the midpoint of BD. if A(-9,-4), C(-1, 6), and E(-4, -3) find coordinates of D

Answers

Answer: The coordinates of D are (-3, -7).

Step-by-step explanation:

First, we need to find the coordinates of B. In order to do that, take the average of the two points that make up the segment which are A and C.

Average of x's: -9 + -1 = -10/2 = -5

Average of y's: -4 + 6 = 2/2 = 1

Therefore, the coordinates of B are (-5, 1). Coordinates are always (x,y).

Now we can find D by noting that the E will be the average of B and D. So we can use the average equation to determine the value of D.

Average of the x's:

(B + D)/2 = E

(-5 + D)/2 = -4

-5 + D = -8

D = -3  

Average of the y's:

(B + D)/2 = E

(1 + D)/2 = -3

1 + D = -6

D = -7

The coordinates of D are (-3, -7).

Two poles, A and B, are 12 meters apart. Pole A is 5 meters high. A rope 20 meters long is tied to the top of pole A and stretches to the top of pole B. What is the height of pole B? Assume that pole B is taller than pole A.

The value of the arithmetic series is 550. The correct answer is C) 550.

To evaluate the arithmetic series, we can use the formula:

Sn = (n/2)(2a1 + (n-1)d)

Given:

a1 = 10 (first term)

d = 8 (common difference)

n = 11 (number of terms)

Plugging the values into the formula:

Sn = (11/2)(2(10) + (11-1)(8))

= (11/2)(20 + 10(8))

= (11/2)(20 + 80)

= (11/2)(100)

= 550

Therefore, the value of the arithmetic series is 550.

The correct answer is C) 550.

What is the equation of the line that passes through the point (-7, 2) and has a
slope of -1

Answers

Answer:

y = -x - 5

Step-by-step explanation:

y = mx + b

slope = m = -1

y = -1x + b

y = -x + b

Plug in (-7, 2) for x and y, and solve for b.

2 = -(-7) + b

2 = 7 + b

b = -5

y = -x - 5

To find:

The property for the given statement.

Solution:

Multiplication property of equality: Let [tex]a,b,c[/tex] are real numbers.

If [tex]a=b[/tex], then [tex]ac=bc[/tex].

We have,

[tex]a=42[/tex]

Using the multiplication property of equality, multiplying both sides by 6.

[tex]6\cdot a=6\cdot 42[/tex]

On simplification, we get

[tex]6a=252[/tex]

Compare the numbers 3.333/10 and 6/10, and that will allow you to determine which of the numbers is larger.

6 is closer to 10 on the number line than 3.33333. Thus the number that is closer to 10, is larger than the other number which is not.

Can someone please help me find the domain of this function

Answers

Given the function,

[tex]t(v) = \sqrt{ {v}^{2} + 2v - 8 } [/tex]

We are aware that square root function is defined for only non negative values.

So,

[tex]\to {v}^{2} + 2v - 8 \geqslant 0[/tex]

[tex] \to{v}^{2} + 4v - 2v- 8 \geqslant 0[/tex]

[tex]\to {v}(v + 4) - 2(v + 4) \geqslant 0[/tex]
