GCF of 9ab^2 and 6bc^2
Alchen [17]

For this case we have that by definition, the GCF (Greatest Common Factor) is the largest integer that divides the numbers.

We have the following expressions:

9ab ^ 2\\6bc ^ 2

We find the factors of 9 and 6:

9: 1,3,9\\6: 1,2,3,6

Thus, the largest number that divides 9 and 6 is 3

It is also observed that "b" is the common variable of both expressions

Therefore, the GCF of the expressions is:

3b

Answer:

3b

Can you help me with this word problem?​
dangina [55]

Answer:

The ratio of flour to sugar is 2:1

Step-by-step explanation:

Let f = weight of a bag of flour

Let s = weight of a bag of sugar

3f+2s = 32

4f = 32

We have 2 equations and 2 unknowns, we can solve

4f=32

Divide by 4

4f/4 = 32/4

f = 8

Each bag of flour weights 8 pounds

Substitute this back into the first equation

3(8) +2s = 32

24+2s = 32

Subtract 24 from each side

24-24 +2s =32-24

2s = 8

Divide by 2

2s/2 = 8/2

s = 4 pounds

Flours weighs 8 pounds and sugar weights 4 pounds

We want the ratio of flour to sugar

Flour: sugar

8:4

We can divide each side by 4

8/4: 4/4

2:1

X = sin 1/2θ, y = cos 1/2θ, −π ≤ θ ≤ π(a) eliminate the parameter to find a cartesian equation of the curve.
Roman55 [17]
First solve for theta in 'x' equation:
\theta = 2 sin^{-1} x

Substitute into 'y' equation:
y = cos (\frac{2 sin^{-1} x}{2}) = cos (sin^{-1} x)

Simplify by rewriting cos in terms of sine.
Using pythagorean identity: sin^2 + cos^2 = 1

cos = \sqrt{1-sin^2} \\  \\ y = \sqrt{1-sin^2 (sin^{-1} x)}
Simplify using inverse function property: f(f^{-1} (x)) = x

y = \sqrt{1 - x^2}
