Given the points (-4,8)and(6,-12)

MissTica

Answer:

$midpoint = ( \frac{ - 4 + 6}{2} , \: \frac{ - 12 + 8}{2} ) \\ = (1, \: - 2)$

$distance = \sqrt{ {( - 4 - 6)}^{2} + {( - 12 - 8)}^{2} } \\ = \sqrt{500} \\ = 22.4 \: units$

A right regular pentagonal prism has a base edge length 14 cm, and height 12 cm. Identify the volume of the prism to the nearest

maks197457 [2]

Answer:

4046.56 cm3

Step-by-step explanation:

The base is made by 5 isosceles triangles, with one side of 14 cm, and the opposite angle of $\frac{360} 5 = 72°$ . Each of the other angle is $\frac{180-72} {2} =54°$ . From there, you can calculate the height of each base triangle as in $\frac {h} 7 = tan54$ or 9.634...cm.

Your volume will be $5 * \frac {(14 * 9.634)} 2 * 12 = 4046.56 cm^3$

The average number of points you scored in the first 9 basketball games of the season was 23. What do you need in the 10th game

Vlada [557]

Answer:

B. 10n-207

Step-by-step explanation:

Given,

The average number of points of 9 games = 23,

∵ Sum of observations = their average × number of observations

So, the total points for 9 games = 9 × 23 = 207,

Now, if the average of 10 games is n,

Then the total points for 10 games = 10n,

Hence, the number of points earned in 10th game = the total points for 10 games - the total points for 9 games

= 10n - 207

i.e. OPTION B is correct.

Write an equation in point slope and slope intercept form of a line that passes through the given point and has the given slope

Evgesh-ka [11]

Answer:

Point-Slope: $y+4=-\frac{1}{2}(x+3)$

Slope-Intercept: $y=-\frac{1}{2}x-\frac{11}{2}$

Step-by-step explanation:

The point-slope formula is $y-y_{1}=m(x-x_{1} )$ . The slope-intercept formula is $y=mx+b$ . Since we are given the point and slope, we can directly plug it into the point-slope formula.
