HELP PLEASE EQUATION OF PARABOLA

Mathematics
1 answer:
Masteriza [31]3 years ago
6 0

It has a minimum value at x = 3 and f(x) = 4

Vertex form is

f(x) = a(x - 3)^2 + 4 where a is some constant to be found

From the graph when x = 5 f(x) = 15, so

15 = a * 2^2 + 4

a = 15-4/4 = 11/4

so our equation is f(x) = 11/4(x - 3)^2 + 4

Mr. Drysdale earned 906.25 in interest in one year on money that he had deposited in
VikaD [51]

Answer: Mr Drysdale deposited 14,500

Step-by-step explanation:

Using the simple Interest formula

Simple Interest = Principal(Initial Money) * Interest Rate * Time Period

I = P*R*T

I = PRT

To get P which is the initial money he deposited, we divide both sides by RT

I/RT = PRT/RT

I/RT = P

Therefore the money deposited

P = I/RT

Interest (I)= 906.25

Interest Rate (R)= 6.25% = { converting percentage to decimal} (6.25/100)= 0.0625

Time Period (T) = 1 year

Principal (P)= ?

P= I/RT

P= 906.25/(0.0625 * 1)

P= 906.25/0.0625

P= 1450

The money he deposited in his local bank is 14,500

Find the value of x.<br><br> Please help and can somebody tell me how to find x?
Olegator [25]

Answer:

x = 75°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

78° + 27° + x° = 180°

Add like terms

105 + x = 180

105 + x - 105 = 180 - 105 (substraction property of equality)

x = 75°
