Answer:

centre= (2,-3)

radius=2

equation= (x-2)^2+(y+3)^2= 4

Step-by-step explanation:

equation is found by the co-ordinates and the length of the radius

if the co-ordinates (2,-3)

x=2

y=-3

r= 2

so the equation will be like

=(x-2)^2+(y+3)^2=2^2

=(x-2)^2+(y+3)^2=4

Thankyou ^^

Rate (R) = 25/3<br>Interest = Rs. 350<br>(d) Principal = Rs. 2400<br><br>Find the time (t)

julia-pushkina [17]

Answer:

The value of t is 1.75 years.

Step-by-step explanation:

Given that simple interest formula is I = (P×R×T)/100. So you have to substitute the following values into the formula :

$i = \frac{prt}{100}$

$let \: i = 350,p = 2400,r = \frac{25}{3}$

$350 = \frac{2400 \times \frac{25}{3} \times t }{100}$

$350 = \frac{20000t}{100}$

$350 \times 100 = 20000t$

$20000t = 35000$

$t = 35000 \div 20000$

$t = 35 \div 20$

$t = 1.75 \: years$

You toss a coin a randomly selecte a number from 0 to 9. What is the probability of getting tails and selecting a 9?

In-s [12.5K]

First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.

Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.

To find them combined, multiply:

1/2 * 1/10
1/20
0.05

Hope this helps!
