Find the center and radius of the circle with equation (x + 8)2 + (y + 3)2 = 49.

Answer:

if you still need this is answer its C.

Step-by-step explanation:

C. HOPE THIS HELPS

Center is at (h,k) in standard form:

(x-h)2 + (y-k)2 = r2

Center: (-8, -3)

Radius (r): sr49 = 7

(x-h)2 + (y-k)2 = r2

Center: (-8, -3)

Radius (r): sr49 = 7

A fair coin is tossed 25 times. what is the probability that at most 24 heads occur?

The probability that at most 24 heads occur is; 24/25.

What do we mean by probability?Probability is the branch of mathematics that deals with numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true. The probability of all the events occurring need to be 1.

We have been given that a fair coin is tossed 25 times.

So, We need to find the probability:

Favourable outcomes = 24

Total outcomes = 25

The formula of probability = Favourable outcomes/Total outcomes

⇒ 24 /25

Therefore, the probability that at most 24 heads occur is; 24/25.

Very rare. Because 25 is a high chance of it always being heads.

What is the value of the expression when p = –16 and q = 4?

4p/q

So subsitute

(4 times -16)/4=-64/4=-32/2=-16/1=-16

or

(4 times -16)/4=4/4 times -16/1=1 times -16=-16

answer is -16

(4 times -16)/4=-64/4=-32/2=-16/1=-16

or

(4 times -16)/4=4/4 times -16/1=1 times -16=-16

answer is -16

We are simply trying to solve: 4p/q.

p = -16, q = 4.

= 4p/q = 4 * -16 / 4 = -16. 4 below divides into 4 at top. Left with -16 at top.

Answer = -16.

p = -16, q = 4.

= 4p/q = 4 * -16 / 4 = -16. 4 below divides into 4 at top. Left with -16 at top.

Answer = -16.

Which of the following points does not lie on the graph of y = 5x - 5? (0, -5)

(1, 0)

(-5, 0)

Y=5x-5 (0,-5) (1,0) (-5,0)

-5=5(0)-5

-5=-5

0=5(1)-5

0=5-5

0=0

0=5(-5)-5

0=-25-5

0=-30

the following point that does not lie on the graph of y=5x-5 is point (-5,0)

-5=5(0)-5

-5=-5

0=5(1)-5

0=5-5

0=0

0=5(-5)-5

0=-25-5

0=-30

the following point that does not lie on the graph of y=5x-5 is point (-5,0)

Answer:

(-5,0)

The club's total number of members will grow exponentially each month. She uses the given expression to model the number of club members, in hundreds, after advertising for t months. 1.8(1.02)^12t

What does the value 1.8 represent?

Answer:

1.8 represents the initial number of the club members in hundreds.

Step-by-step explanation:

* Lets revise the exponential grows

- If a quantity grows by a fixed percent at regular intervals,

the pattern can be depicted by this function.

- The function of the exponential growth is:

y = a(1 + r)^x

# a = initial value (the amount before measuring growth)

# r = growth rate (most often represented as a percentage and

expressed as a decimal)

# x = number of time intervals that have passed

* Now Lets study the problem to solve it

- The club's total number of members will grow exponentially

each month

- The expression to model the number of club members, in

hundreds, after advertising for t months is

1.8(1.02)^12t

* Lets compare between this model and the function above

# a = 1.8 ⇒ initial number of members in hundreds

# r = 1.02 - 1 = 0.02 ⇒ growth rate

# x = 12t ⇒ number of time intervals

* 1.8 represents the initial number of the club members in hundreds.
