Right triangle ABC is located at A (−1, 4), B (−1, 1), and C (−5, 1) on a coordinate plane. What is the equation of a circle A w
alexandr1967 [171]

The circle is in A, so (-1, 4) coords

(x - xo)² + (y - yo)² = r²

(x - (-1))² + (y - 4)² = r²

(x + 1)² + (y - 4)² = r²

And the radius is the length of segment AC

distance of AC is

\sqrt{(yc-ya)^2+(xc-xa)^2}

\sqrt{(1-4)^2+(-5-(-1))^2}

\sqrt{(-3)^2+(-4)^2}

\sqrt{9+16}

\sqrt{25}

5

So r = 5

(x + 1)² + (y - 4)² = 5²

(x + 1)² + (y - 4)² = 25

What’s the answer ??
scoundrel [369]
So to find the answer, you'll have to substitute b for 6 and a for 1/4 as shown. Then, you will get 5(6)/32(1/4)^2.
Now, all you have to do is just calculate it, which you will get 15 as your final answer.
I hope this helps :)

Using Postulates and/or Theorems, determine whether ABC~AXY.
Xelga [282]

Answer:

They are not similar

Step-by-step explanation:

To see whether the triangles are similar or not we can compare their side lengths:

AB = 24

AX = 6

AX/AB = 1/4 is the ratio now let's compare this to AY/AC

AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.

A car rental agency rents 190 cars per day at a rate of 29 dollars per day. for each 1 dollar increase in the daily rate, 5 fewe
Leviafan [203]

The equation that we can create from this situation is:

i = (190 – 5 x) * (29 + x)

where i is the income and x is the increase in daily rate

Expanding the equation:

i = 5510 + 190x – 145x - 5x^2

i = -5x^2 + 45x + 5510

Taking the 1st derivative:

di/dx = -10x +45

Set to zero to get the maxima:

-10x + 45 = 0

x = 4.5

 

So the cars should be rented at:

29 + x = 33.5 dollars per day

 

The maximum income is:

i = (190 – 5*4.5) * (33.5)

i = 5,611.25 dollars
