Prove that the two circles shown below are similar.

Setler [38]

Answer:

The scale factor is $\frac{R_{A}}{R_{C}}=\frac{5}{2}$

We can say that both circles are similar.

Step-by-step explanation:

If we move the little circle to the center of the bigger circle, so the translate vector will be (3,5).

Now we realize that the bigger circle is just a dilation of the smaller circle, the scale factor is:

$R_{A}=5$

$R_{C}=2$

$\frac{R_{A}}{R_{C}}=\frac{5}{2}$

Therefore, we can say that both circles are similiar.

I hope it helps you!

A machine dispenses water into a glass. Assuming that the amount of water dispensed follows a continuous uniform distribution fr

natima [27]

Answer:

(a) 13 ounces.

(b) 1.732 ounces.

(c) 0.5

(d) 0.33

Step-by-step explanation:

Given : The amount of water dispensed follows a continuous uniform distribution from 10 ounces to 16 ounces. So, a=10 and b=16.

(a) The average amount of water dispensed by the machine = (a+b)/2 = (10+16)/2 = 13 ounces.

(b) The standard deviation of the amount of water dispensed = $\int\limits^a_b {\frac{(b-a)^{2} }{12} } \, dx \\$ = √36/12 =√3 = 1.732 ounces.

(c) P (13 or more ounces will be dispensed in a given glass) = $\int\limits^a_b {f(x)} \, dx$ = $\int\limits^b_a {\frac{dx}{b-a} } \, dx$ = 0.5

(d) P (between 12 and 14 ounces will be dispensed in a given glass) = ( here a=12 and b=14.) $\int\limits^a_b {f(x)} \, dx$ = $\int\limits^b_a {\frac{dx}{b-a} } \, dx$ = 0.33

The product of two whole numbers is 490 and their sum is 49. What are the two numbers?

larisa86 [58]

Answer:

Step-by-step explanation:

x*y = 490

x + y = 49

x = 49 - y

y*(49 - y ) = 490

49y - y^2 = 490

0 = y^2 - 49y + 490

This does factor (oddly). It doesn't look like it, but it does.

(y - 35) (y - 14) = 0

y - 35 = 0

y = 35

y - 14 = 0

y = 14

x = 49 - y

Let y = 14

x = 49 - 14

x = 35

x = 49 - y

let y = 35

x = 49 - 35

y = 14

Solutions

(35,14)

(14,35) Both solutions are valid.
