4 0

Answer:

The answer is

<h2>( - 8 \: , \:  -  \frac{1}{2} )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} ) \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-8, 3), (-8,-4)

The midpoint is

M = ( \frac{ - 8 - 8}{2}  \:   , \:  \frac{3 - 4}{2} ) \\    = ( -  \frac{16}{2}  \: , \:  -  \frac{1}{2} )

We have the final answer as

( - 8 \: , \:  -  \frac{1}{2} )

Hope this helps you

Answer:

Since f(25\,ft) < 8\,ft, then we conclude that it will be a goal.

Step-by-step explanation:

Let the trajectory of the ball be represented by f(x) = -0.05\cdot (x-16)^{2}+11, where x is the horizontal distance of the ball from origin, in feet, and f(x) is the height of the ball above ground, in feet.

If Deshawn does not block Chris's shot, then we should check if shot will be a goal and this condition must be fulfilled:

f(25\,ft) < 8\,ft (1)

If we know that x = 25\,ft, then the height of the ball at the start of the goal is:

f(x) = -0.05\cdot (x-16)^{2}+11 (2)

f(x) = 6.95\,ft

Since f(25\,ft) < 8\,ft, then we conclude that it will be a goal.

Please help! i will give u 20 points I need the answer with the method
olga55 [171]

Answer:

6 mm

Step-by-step explanation:

So, the area he needs to fill isn't really important, you don't need to calculate it. What is necessary is the individual dimensions of that area (width/length). The width and the length must be divisible by the lengths of the tiles. This is so you don't need to cut anything. For example let's say the area needed to be filled was 15 mm (width) by 10 mm (length). If I chose 3mm square tiles, it could perfectly fill up the width, but when it came to the length there would be a small 1 mm gap. And you would need to cut one of the square tiles, so it would have a length of 1 mm. In this case the 15mm was divisible by 3, but the 10 mm wasn't. So using this logic, it can't be the 4 mm square tile since 150mm / 4 mm = 37.5. It can be the 6m since 150mm / 6mm = 25 and 180 mm / 6mm = 30. It can't be the 8 mm since 150 mm / 8mm = 18.75 mm

A fireplace arch is to be constructed in the form of a semiellipse. The opening is to have a height of 3 feet at the center and
USPshnik [31]

Answer:

Step-by-step explanation:

Given

Fireplace is in the form of semi-ellipse  with height of 3 ft from center

Length of base=8 ft

if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis

2 a =8

a=4 ft

If contractor cover the whole base

then total length of string=2a =8 ft

(b)String should be nailed at focus

focus of ellipse is a e

where e=eccentricity

e=\sqrt{1-(\frac{b}{a})^2}

e=\sqrt{1-(\frac{3}{4})^2}=\frac{\sqrt{7}}{4}

Focus =ae =\sqrt{7}

Thus string should be nailed at 2.64 m from center
