2. Factorise : (i) 9x² + y² + 64 - 6xy +16y - 48x​

Answers

Answer:

9x² + y² + 64 - 6xy - 16y - 48x

= 9x² - 6xy - 48x + y² - 16y + 64

= 9x² - 6x(y - 8) + y² - 2.8y + 8²

= (3x)² - 6x(y - 8) + (y - 8)²

= [3x - (y - 8)]²

= (3x - y + 8)²

Michael uses a blend of dark chocolate and milk chocolate to make the ice cream topping at his restaurant. He needs to buy 100 kg of chocolate in total for his next order. Dark chocolate costs $12 per kilogram, milk chocolate costs $10 per kilogram, and he wants to spend $1120 total.

Let d be the number of kilograms of dark chocolate he buys and m be the number of kilograms of milk chocolate he buys.

Which system of equations represents this situation?

Answers

Answer:

d + m = 100

12d + 10m = 1120

Step-by-step explanation:

d = 60

m = 40

Answer: 60 kg dark chocolate, 40 kg milk chocolate

Step-by-step explanation:

Okie soooo

Let's name the variables (which they did for us lol)

d = kg of dark chocolate and m = kg of milk chocolate

He needs 100 kg of chocolate

d + m = 100

and he wants to spend 1120 when dark chocolate costs $12/kg and milk chocolate costs $10/kg

12d + 10m = 1120

Now we solve the system (I shall use elimination method)

Multiply the first equation my -10

-10(d + m) = (100)(-10)

which becomes

-10d - 10m = -1000

12d + 10m = 1120 (rewrite the second equation)

------------------------- (add the two equations together)

2d = 120

d = 60

now substitute d into either equation

60 + m = 100

m = 40

60 kg dark chocolate

40 kg milk chocolate

A right rectangular prism has a volume of

What are expressions for the length, width, and height?​

Answers

Answer:

3x, 2x + 5, and x - 3

Step-by-step explanation:

Since the given figure is a 3-dimensional shape, we know that there must be three zeroes.

Our equation is:

6x³ - 3x² - 45x

First, we can factor out an x:

x (6x² - 3x - 45)

From here, we can see that by factoring out a 3:

3x (2x² - x - 15)

Now, after completing the square and factoring:

3x (2x + 5) (x - 3)

These are our three expressions.

What is perimeter of the semi circle?

Answers

Answer:

54.22 mm

Step-by-step explanation:

Find the circumference of the circle and then divide it by 2.

We start with the formula for the circumference for the circle:

C = 2πr

To find r, divide 22 by 2:

22/2=11

Now find the cicumference:

C = 2πr = 2(3.14)(11) = 108.46 mm

NOW, to find the perimeter of the semicircle, divide the circumference by 2:

108.46/2 = 54.22 mm

What is a, the initial amount, for the function: f(x) = 300(1.16)*?

Answers

Answer:   300

====================================================

Explanation:

One general template of exponential functions is

f(x) = a*(b)^x

The 'a' is the initial amount, which in this case is a = 300

----------------------

Extra info:

The b is the base of the exponential, which is b = 1.16

The value of b is helpful to determine if you have exponential growth or decay, and how much of either. Because b = 1.16 is greater than 1, it indicates exponential growth. The rate of growth is found by solving 1+r = 1.16 to get r = 0.16, which leads to 16% growth.
