Answer 1

Answer:

y = - 3x² - 24x - 60

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (- 4, - 12 ), thus

y = a(x + 4)² - 12

To calculate a substitute (- 7, - 39) into the equation

- 39 = a(- 7 + 4)² - 12 ( add 12 to both sides )

- 27 = 9a ( divide both sides by 9 )

- 3 = a

y = - 3(x + 4)² - 12 ← in vertex form

Expand (x + 4)²

y = - 3(x² + 8x + 16) - 12

   = - 3x² - 24x - 48 - 12

y = - 3x² - 24x - 60 ← in standard form

   = - 3(x²

Answer:

g(x) = |x-5|

Step-by-step explanation:

f(x) = |x|

y = f(x + C)  C < 0 moves it right

g(x) = |x-5| moves it to the right 5 units

We start off with: f(x) = |x|

c < 0 means move right

y = f(x + c)

Move 5 units to the right

After: g(x) = |x - 5|

Answers

Answer: (6,-10)

Step-by-step explanation:

When you reflect a point over the y-axis, the sign of the number changes. It goes from negative to positive and positive to negative. Since both our numbers are positive, only the y-coordinate become negative because it is only being reflected over the y-axis, not x-axis. (6,-10)

What is the square root of 586

Answers

here’s everything you might need to know! hope this helps!!

Square root of 586 definition
The square root of 586 in mathematical form is written with the radical sign like this √586. We call this the square root of 586 in radical form. The square root of 586 is a quantity (q) that when multiplied by itself will equal 586.

√586 = q × q = q2

Is 586 a perfect square?
586 is a perfect square if the square root of 586 equals a whole number. As we have calculated further down on this page, the square root of 586 is not a whole number.

586 is not a perfect square.
Is the square root of 586 rational or irrational?
The square root of 586 is a rational number if 586 is a perfect square. It is an irrational number if it is not a perfect square. Since 586 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 586?" will have an infinite number of decimals. The decimals will not terminate and you cannot make it into an exact fraction.

√586 is an irrational number


Can the square root of 586 be simplified?
You can simplify 586 if you can make 586 inside the radical smaller. We call this process "to simplify a surd". The square root of 586 cannot be simplified.

√586 is already in its simplest radical form.


How to calculate the square root of 586 with a calculator
The easiest and most boring way to calculate the square root of 586 is to use your calculator! Simply type in 586 followed by √x to get the answer. We did that with our calculator and got the following answer with 9 decimal numbers:

Aaron puts $1,000 in an account that pays 10% interest compounded quarterly. He leaves it in the account for six months. Estimate how much interest he earns.

Answers

Answer: $50.63 --- Interest

Step-by-step explanation:

Step 1

Using the formulae

A = P(1 + r/n)^nt

Where

A = principal + interest Amount

P = Principal Amount = $1000

t = Time  in years= 6months = 0.5 years

n = number of compounding periods= quarterly =4

Step 2

6 months = 6/12 = 0.5 years

Rate = 10 % = 0.1

A = P(1 + r/n)^nt

= 1000 ( 1 + 0.1/4)^(4 x 0.5)

=1000(1 +0.025)^2

= 1000(1.025)^2

= 1000 x 1.050625

A= $1,050.625

but A = principal + interest Amount

Interest = A- Principal=$1,050.625-$1,000

=$50.625

The recipe below makes enough
fruit punch for 1 person.

1/2 lime
1/2 lemon
100ml pineapple juice 200ml lemonade 100ml orange juice
1) How much of each ingredient will she need?

Limes
Lemons Pineapple juice Lemonade Orange juice
Cost of ingredients:
Pineapple Juice
Lemons 50 each
Limes 40c each
Lemonade (2 liter bottle) $1.60
Orange juice (1 liter carton) 80c
Pineapoe juice (1 liter carton) 90c

Answers

Answer:

1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice

2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c

Step-by-step explanation:

1/2 limes · 10 = 5

1/2 lemons · 10 = 5

100 mL of pineapple juice · 10 = 1,000 mL

200 mL of lemonade · 10 = 2,000 mL

100 mL of orange juice · 10 = 1,000 mL

Cost:

5 limes · 0.4 = $2

5 lemons · 0.5 = $2.5

mL to L

1,000 mL of pineapple juice = 1 L, this costs 90¢

2,000 mL of lemonade = 2 L, this costs $1.60

1,000 mL of orange juice = 1 L, this costs 80¢

Overall:

5 limes for $2

5 lemons for $2.5

1 L of of pineapple juice for 90¢

2 L of lemonade for $1.60

1 L of orange juice for 80¢
