Answer:

Step-by-step explanation:
For this case we have the following profit function:

And we are interested on find the profit after selling 700 pretzels, so we just need to replace X=700 into the profit function like this:

The profit function is on the figure attached. We see that for 0<X<217 we have negative profits, and for X>217 we will have positive values for the profit. And also we can see that for X=700 we have a profit of approximately 169.
ANSWER

EXPLANATION
Method 1
Vertically opposite angles are equal, therefore

This implies that,

We simplify to get,

Dividing through by 3 gives,

Also,

This implies that,

We simplify the right hand side to get,

We divide both sides both sides by 2 to get,



Method 2
Angles on straight line sums to 180°.

This implies that,




Also,






Answer:
(5)2
Step-by-step explanation:
As we know that the equation of circle with center at (h,k) ad radius r is given as-
(x−h)
2
+(y−k)
2
=r
2
Given that the centre of circle is (1,4) and radius is 5.
Therefore the equation of circle is-
(x−1)
2
+(y−4)
2
=(5)

Its the purple graph that looks like a upside down V because all the values are negative due to the "-" being outside the absolute value symbols.
you can also graph it as y=-|x|
