Answer:

The answer to your question is (1/2, -5/2)

Step-by-step explanation:

Data

A = (-1, -9)

B = (2, 4)

Formula of midpoint

Xm = (x1 + x2) / 2

Ym = (y1 + y2)/2

x1 = -1 y1 = -9 x2 = 2 y2 = 4

To solve this problem just substitute the values in the formula and simplify.

Xm = (-1 + 2) / 2

Ym = (-9 + 4) / 2

-Simplify

Xm = 1/2

Ym = -5/2

-Solution

Answer:

Midpoint( .5,-2.5)

Step-by-step explanation:

To find the midpoint, add the x coordinates and divide by 2 and then add the y coordinates and divide by 2

x: (-1+2)/2 = 1/2=.5

y: (-9+4)/2 = -5/2 = -2.5

Midpoint( .5,-2.5)

What are the partial products that result from multiplying 15x32?

pashok25 [27]

The answer to this question would be: 300; 20; 150; 10

When you multiply 15 x 32, you can divide both numbers into this:
15= 10 + 5
32= 30 +2

Then the multiplication becomes (10+5) * (30+2) which will result in 4 partial product like this:
10*30= 300
10* 2= 20
5* 30= 150
5* 2= 10

Complete the square to rewrite x^2+y^2+2x+6y-6=0 in graphing form

Ksivusya [100]

Answer:

(x + 1)² + (y + 3)² = 16

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

x² + y² + 2x + 6y - 6 = 0

Collect the x and y terms together and add 6 to both sides

x² + 2x + y² + 6y = 6

To complete the square

add ( half the coefficient of the x/ y terms )² to both sides

x² + 2(1)x + 1 + y² + 2(3)y + 9 = 6 + 1 + 9

(x + 1)² + (y + 3)² = 16

with centre = (- 1, - 3) and r = $\sqrt{16}$ = 4

Let angle G be an acute angle and tan G = 0.43 . Use technology to approximate the measure of angle G to the nearest 10th of a d

klasskru [66]

We need to use the calculator, using the tan⁻¹ function:

$\begin{gathered} \tan(G)=0.43 \\ \tan^{-1}(\tan(G))=\tan^{-1}(0.43) \\ G=\tan^{-1}(0.43) \end{gathered}$

Using the calculator:

$G=\tan^{-1}(0.43)=23.26770481$

To the nearest tenth:

$G=23.3º$

The triangles are similar.

RSB [31]

Answer:

The value of x is 12.

Step-by-step explanation:

In order to find the value of x, we first need to find the scale factor. We can find this by dividing any side of the larger triangle with the corresponding part of the smaller triangle.

28/7 = 4

This means everything in the larger triangle is 4 times as great as the smaller triangle. Knowing this, we can set the larger hypotenuse equal to 4 times the smaller.

6x + 28 = 4(25)

6x + 28 = 100

6x = 72

x = 12
