Answer:

Step-by-step explanation:

11. Write in point slope form first;

y+4 = (x+1)^2; Convert to standard form;

y=x^2+2x+1-4

y = x^2+2x-3; Final standard form

12. Convert the original point-slope form with the vertex given;

y-3 = a(x-4)^2; plug in the point (1,12) to solve for a;

12 -3 = a(1-4)^2

9 = 9a

a = 1

y-3 = (x-4)^2

y=(x-4)^2+3: Final vertex from

13. The vertex is at (-1,-4)

y +4= (x+1)^2; Factored form can mean many things;

this is the equation of the function; factor it how your teacher taught you.

The scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches what is the actual distanc
DanielleElmas [232]

Answer:

4 3/8 miles

Step-by-step explanation:

We are told that: the scale on a map is 1 inch =2 1/2 miles.the distance between two streets on the map is 1 3/4 inches

If 1 inches = 2 1/2 miles

1 3/4 inches =

Cross Multiply

1 3/4 × 2 1/2/1

= 7/4 × 5/2

= 35/8

= 4 3/8 miles

The actual distance between these streets is 4 3/8 miles

The probability that a person is accepted for admission to a specific university is 0.6. Determine the probability that exactly
frozen [14]

Answer: the probability that exactly two of the next five people who apply to that university get accepted is 0.23

Step-by-step explanation:

We would number of people that applies for admission at the university and gets accepted. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - p) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 0.6

q = 1 - p = 1 - 0.6

q = 0.4

n = 5

the probability that exactly two of the next five people who apply to that university get accepted is

P(x = 2) = 5C2 × 0.6^2 × 0.4^(5 - 2)

P(x = 2) = 10 × 0.36 × 0.064

P(x = 2) = 0.23
