For the following product, determine whether the result is rational or irrational and choose the appropriate reason.

5/19 x 4/9

A:The result is rational because the product of a nonzero rational number and an irrational number is sometimes rational.

B:The result is irrational because the product of a nonzero rational number and an irrational number is always irrational.

C:The result is rational because the product of two rational numbers is always rational.

D:The result is irrational because the product of two irrational numbers is sometimes irrational.

Answers

Answer:

Sugar | Flour

¼ | 1

½ | 2

⅝ | 2½

4 | 16

Step-by-step explanation:

¼ part of sugar = 1 part flour (given)

Ratio of sugar to flour = ¼ : 1

Use this proportion to complete the table.

✔️Sugar to flour = ¼ : 1

½ : x = ¼ : 1

½/x = ¼/1

cross multiply

x*¼ = 1*½

x/4 = ½

Multiply both sides by 4

x = ½*4

x = 2

✔️Sugar to flour = ¼ : 1

x : 2½ = ¼ : 1

x : ⁵/2 = ¼ : 1

x/⁵/2 = ¼/1

Cross multiply

x*1 = ¼*⁵/2

x = ⅝

✔️Sugar to flour = ¼ : 1

4 : x = ¼ : 1

⁴/x = ¼/1

Cross multiply

x*¼ = 1*4

x/4 = 4

Multiply both sides by 4

x = 4*4

x = 16

inflection points?

Answers

Answer:

1 and 6

Step-by-step explanation:

it is just like the roots of a polynomial, since [tex]\sqrt{x-1}[/tex](x-6)^2=0

we can separate the two pieces of the problem

\sqrt{x-1} =0

square both sides to get

x-1=0. x=1

(x-6)^2=0

square root both sides and get

x-6=0

x=6

so the two inflection points of the equation are 6 and 1

Bob took his family out to lunch. He bought 3 hot dogs and 2 hamburgers for $11. If the guy in front of him bought 2 hot dogs and 4 hamburgers for $16, what is the cost of one hamburger?

Answers

Answer:

Hotdog: $1.50

Hamburger: $3.25

Step-by-step explanation:

You write down the 2 equations based off of the information as I did:

Let x = cost of a hotdog

Let y = cost of a hamburger

and so:

3x + 2y = 11

2x + 4y = 16

Now, we need to find x and y:

We will make both equations equal to y to compare them to each other.

2y = 11 - 3x

y = 5.5 - 1.5x

4y = 16 - 2x

y = 4 - 0.5x

4 - 0.5x = 5.5 - 1.5x

x = $1.5

Now plugging in x into the equation:

2(1.5) + 4y = 16

3 + 4y = 16

4y = 13

y = $3.25

And so hotdog = $1.5 and hamburger = $3.25

Given the function f(x) = 4x + 1, EXPLAIN and show how to find the average rate of change between x = 1 and x = 3.

Answers

The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula

m = (y2 - y1)/(x2 - x1)

m = (1 - (-3))/(3 - 1)

m = 4/2

m = 2

Therefore the slope, or the average rate of change, between these points is 2.

Average rate of change is another word for the slope. The function you have is presented in slope-intercept form (y=mx+b), where m=your slope. This means that you already know the slope, which is 4.

Just in case you need to show why the slope = 4, I’ll leave how to find it here:

To find the slope, use the formula: y2-y1/x2-x1

First, you need to find the y-values at x=1 and x=3. To do this, plug the x-values into the equation. The value you end up with is your y-value.

f(1) = 4(1) + 1 = 5
f(3) = 4(3) + 1 = 13

So your two points are (1, 5) and (4, 13). Now plug these points into the slope formula

m = (13-5)/(3-1) = 8/2. 8 divided by two is 4, so your average rate of change is 4. You can double check this by graphing.

Answer:

f(t)=t^2 rests at (0/0) and grows upwards, so there is only a single x-intercept. g(t)=(t+3)^2 is f moved 3 to the left, so it also only has one intercept but at (-3,0).
