Answer:

-4, -1, and 5

Step-by-step explanation:

1. The x-intercepts of a function is where the function intersects with the x-axis.

2. Given the information above, we can see that the function intersects the x-axis at (-4,0), (-1,0), and (5,0).

This means that the x-intercepts are -4, -1, and 5.

A is more because 1/4 is equal to 2/8 and 2/8 is less than 7/8 so you would have more than a minute
B is three minutes 2/8 goes into 7/8 three times

M is the incenter of triangle ABC. Find the lengths of MD and DC. (Look at pic)

Deffense [45]

Answer:

Part 1) $MD=9\ units$

Part 2) $DC=12\ units$

Step-by-step explanation:

Step 1

Find the length of MD

we know that

The incenter is the intersection of the angle bisectors of the three vertices of the triangle. Is the point forming the origin of a circle inscribed inside the triangle

In this problem

$MD=ME=MF$ ------> is the radius of a circle inscribed inside the triangle

we have that

$MF=9\ units$

therefore

$ME=9\ units$

$MD=9\ units$

Step 2

Find the length of DC

we know that

In the right triangle MDC

Applying the Pythagoras theorem

$MC^{2} =MD^{2}+DC^{2}$

we have

$MD=9\ units$

$MC=15\ units$

substitute

$15^{2} =9^{2}+DC^{2}$

$DC^{2}=225-81$

$DC=\sqrt{144}\ units$

$DC=12\ units$

The diagonal of a square has length 10√2. Find the area of the square.

alex41 [277]

Answer: $A = 100$ square unit

Step-by-step explanation:

The formula for calculating the area of a square when the diagonal is given is :

$Area = d^{2} / 2$

That is :

$A = \frac{(10\sqrt{2})^{2}}{2}$

$A = \frac{100(2)}{2}$

$A = 100$ square unit
