Ehen you multiply ANYTHING by 10, you add a 0 to the end. In this case, a 0 would nake it still 3.4, so you move the decimal. So 3.4x10=34, which is 3.4 with the decimal moved over.

3x10 equals 30. The .4 is in the tenths place so multiplied by 10 will move it to the ones place.

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

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

$DC^{2}=225-81$

$DC=\sqrt{144}\ units$

$DC=12\ units$

Explain what the slope and intercept mean in the situation.

Vera_Pavlovna [14]

Answer: The slope is the cost per muffin and the intercept of 3 is the delivery charge.

Step-by-step explanation:

I will assume that the graph has total cost in dollars for the y axis and number of muffins on the x axis. A slope of 2 means that y will increase by 2 for every 1 increase in x. That means that the price of a single muffin is $2.

The intercept of 3 at x = 0, means that there is an upfront (delivery) charge of $3. One muffin would cost $2 for the muffin plus $3 for the delivery, for a total of $5.

10 muffins would cost $20 for the muffins plus $3 for the delivery, for a total of $23.
