Answer:

Solution given:

short cut to find x

Tan 30°=P/B

Tan30°=x/22√3

x=tan 30×22√3

x=22

and

for y

cos 30=B/H

cos30×y=22√3

y=22√3/cos30

y=44

Write the equation of the circle centered at (0,1) with radius 15.

NNADVOKAT [17]

Answer:

$x^2+(y-1)^2=225$

Step-by-step explanation:

we know that

The equation of the circle in center radius form is equal to

$(x-h)^2+(y-k)^2=r^2$

where

(h,k) is the center of the circle

r is the radius of the circle

In this problem we have

$(h,k)=(0,1)\\r=15\ units$

substitute

$(x-0)^2+(y-1)^2=15^2$

$x^2+(y-1)^2=225$

The correct answer to the question above is 4/13. Below it shows how it's achieved...

EQUATION:
P(A|B) = P(A ∩ B)
 P(B)

Step 1: Identify
P(B) = 5/14
P(A ∩ B) = 10/91

Step 2: Insert into the equation and Solve
10/91 ÷ 5/14
Use reciprocal to divide
10/91 × 14/5
Simplify the answer
140/455
Simplified (Final Answer)
4/13
