I’m pretty sure it would be equilateral because all the sides are the same:)

Find its x-coordinate.

Ilya [14]

Answer:

2.5

Step-by-step explanation:

The formula to find the midpoint of a line segment: $(\frac{1}{2}x_{1} + \frac{1}{2}x_{2}, \frac{1}{2}y_{1} + \frac{1}{2}y_{2})$

<u><em>Where:</em></u>

$x_{1} = -5\\x_{2} = 10\\y_{1} = 9\\y_{2} = 8$

1) Substitute the values into the midpoint formula.

$(\frac{1}{2}*-5 + \frac{1}{2}*10, \frac{1}{2}*9 + \frac{1}{2}*8)$

2) Solve it.

= $(-2.5 + 5, 4.5 + 4)$

= (2.5, 8.5)

The dimensions of a portable kennel can be expressed as width x, length x + 0.4, and height x − 0.2? What are the dimensions of

horsena [70]

Answer:

$L=2.3\ ft\\W=1.9\ ft\\H=1.7\ ft$

Step-by-step explanation:

we know that

The volume of a portable kennel (rectangular prism) is equal to

$V=LWH$

where

$L=(x+0.4)\ ft\\W=x\ ft\\H=(x-0.2)\ ft$

$V=7.4\ ft^3$

substitute the given values in the formula of volume

$7.4=(x+0.4)(x)(x-0.2)$

Apply distributive property right side

$7.4=x(x^2-0.2x+0.4x-0.08)$

$7.4=x(x^2+0.2x-0.08)$

$7.4=x^3+0.2x^2-0.08x$

$x^3+0.2x^2-0.08x-7.4=0$

Solve the cubic equation by graphing

using a graphing tool

The solution is x=1.9

see the attached figure

Find the dimensions

substitute the value of x

$L=(1.9+0.4)=2.3\ ft\\W=1.9\ ft\\H=(1.9-0.2)=1.7\ ft$

Help please logarithms

DochEvi [55]

Answer:

Simplified: 40

Step-by-step explanation:

To simplify this, we need to first separate the terms in this expression. There is a property of exponents that says: $x^{a+b} =x^ax^b$ We can do this same thing to simplify this expression. Next, we can simplify each of these terms. $2^2$ simply becomes 4. In the other term, the $2^{log_2}$ simply cancel each other and leave the 10. This means that we're left with 4*10, which is 40

$2^{2+log_210} \\\\2^2*2^{log_210} \\\\4*10\\\\40$
