Has endpoints q(4, 10) and s(–2, 3). find the coordinates of the midpoint of . (1, 6.5) (1, 13) (6.5, 3.5) (6.5, 1)

1 answer:

5 0

The midpoint is (1, 6.5)

The best way to find the midpoint of a line is by taking the average of its respective coordinates.

The average of the x coordinates 4 and -2 is 1 because when they are added together and divided by 2 you get 1.

Similarly for the y coordinates, which are 10 and 3. Added together they give an answer of 13 and when that is divided by 2 we get 6.5.

3,2

Step-by-step explanation:

Reflection across the x-axis:

(x,y) -> (x,-y)

In other words, you want to change the sign of the y.

(3,-2) -> (3,2)

A conical paper cup has a radius of 2 inches. Approximate, to the nearest degree, the angle β (see the figure) so that the cone

Aneli [31]

I don't know where the angle β is, so I will make the assumption that tanβ = h/r
$V = \frac{1}{3} \pi r^{2} h$

V volume = 60
r radius = 2
h = r tanβ

$tan \beta = \frac{3V }{ \pi r^{3} } = \frac{ 180}{25,1} = 7,17 \\ \\ \beta = 82$

In the expression -5g12 whIn the expression -5g12 which part is the coefficient?ich part is the base?

kiruha [24]

Answer:

The coefficient is -5, and the base is 12.

Step-by-step explanation:

The coefficient is the number that the variable is being multiplied by in an expression, so -5 would be the coefficient in the expression $-5g_{12}$ . The base would be the little subscript number that is next to the variable, so the base in the expression $-5g_{12}$ is 12.

13(y+3)=13y+39 how many solution

Jobisdone [24]

13(y+3)=13y+39

mutiply the bracket by 13

(13)(y)= 13y

(13)(3)= 39

13y+39= 13y+39

move 13y to the right side

sign changes from +13y to -13y

13y-13y+39= 13y-13y+39

0+39= 0+39

39= 39
