Answer:

5, -35, 3.75, 4a + 4b + 5

Step-by-step explanation:

1. f(0) = 3(0)^2 - 2(0) + 5 = 5

2. f(-4) = 3(-4)^2 - 2(-4) + 5 = -35

3. f(-1/2) = 3(-1/2)^2 - 2(-1/2) + 5 = 3.75

4. f(a+b) = 3(a+b)^2 - 2(a+b) +5 = 4a + 4b + 5

3(a+b)(a+b) - 2a -2b + 5

6a + 6b -2a -2b +5

These are our two tables of values for the following functions using the integers from -4 to 4.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

The given functions using the integers from -4 to 4 are

a. F(x)=6/x-2b.

r(x)=6x+12/x²-4

According to given question we have

f(x) = 6/x - 2

Now we just need to evaluate the function in all the given points:

a) f(x) = 6/x - 2

Now we can put the value

f(-4) = 6/(-4) - 2 =  -3/2 - 4/2 = -7/2

f(-3) = 6/-3 - 2 = -4

f(-2) = 6/-2 - 2 = -5

f(-1) = 6/-1 - 2 = -8

f(0) is undefined

f(1) = 6/1 - 2 = 4

f(2) = 6/2 - 2 = 1

f(3) = 6/3 - 2 = 0

f(4) = 6/4 - 2 = -1/2

b. r(x)=6x+12/x²-4

Now we can put the value

r(-4) = 6(-4)+12/(-4)²-4=-27.25

r(-3) = 6(-3)+12/(-3)²-4=-20.66

r(-2) = 6(-2)+12/(-2)²-4=-13

r(-1) = 6(-1)+12/(-1)²-4= 2

r(0) = 6(0)+12/(0)²-4= ∞

r(1) = 6(1)+12/(1)²-4 =14

r(2) = 6(2)+12/(2)²-4=11

r(3) = 6(3)+12/(3)²-4 =15.33

r(4) = 6(4)+12/(4)²-4=20.75

Therefore, these are our two tables of values for the following functions using the integers from -4 to 4.

Step-by-step explanation:

The distinction between present value and future value is that the former is required now and the latter is needed at a future period

What is the difference between present value and future value?

The present value indicates today's worth or dollars of a future value  of a  flow whereas the future value determines the future worth of an investment or deposit made today or deposits over a number of years at a time in the future

The amount that Claudia would have in a year's time is future value because the present value is the initial deposit made today

The amount that Steven would  have to deposit today in order to accumulate $400,000 in 15 years is the present value

The amount that a deposit of $4,500 made today would worth in 6 years is the future value because the initial deposit is the present value.

Joe would have to deposit payments in expectation of future value after 3 years and the deposit required today to earn a rate of return of 5% in order to have $1000 in 5 years is a present value

Hope this helps a little. :)

Step-by-step explanation:

2 cups of sugar mix with 7 cups of water.

so, 2/2 = 1 cup of sugar mixes therefore with 7/2 = 3.5 cups of water.

and 5 cups of sugar (= 5×1 cups) mix with 5×3.5 = 17.5 cups of water.

not 21. not 28. it is 17.5 cups of water !

Answer:

AB and CD are congruent.

Step-by-step explanation:

Given points:

To determine if AB and CD are congruent, calculate the length of the two lines using the distance formula.

[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}\implies AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-4)^2+(6-1)^2}\\& = \sqrt{(-2)^2+(5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]

[tex]\begin{aligned}\implies CD & = \sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\& = \sqrt{(-4-(-2))^2+(-3-2)^2\\& = \sqrt{(-2)^2+(-5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]

Therefore, as AB = CD, we can conclude that AB and CD are congruent.

Using the calorie count C for a serving of food C =5h + 8f + 5​p, the formula for f is derived to be; f = (C - 5h  - 5​p) / 8

An equation is an expression that shows the relationship between two or more numbers and variables.

WE have been Given data that C =5h + 8f + 5​p

Where C is the calorie count, h is the number of grams of carbohydrate, f is the number of grams of fat and p is the number of grams of protein

Now solving for f in the given equation;

C = 5h + 8f + 5​p

Then f the subject of formula;

C - 5h  - 5​p = + 8f

8f = C - 5h  - 5​p

Now dividing through by 8

f = (C - 5h  - 5​p) / 8

Hence, The number of grams of fat, f, contained in a serving of food is; f = (C - 5h  - 5​p) / 8

Use the roster method to write each of the given sets. the set of natural numbers x that satisfy x + 6 = 5.

There is no set of natural numbers of x that satisfy the condition for x+6=5

Roster method is nothing but listing the items of a set inside brackets, the roster method provides a means to display the set's components.

For Example, A={1,2,3,4,5}

The Natural numbers is the category of numbers known as "natural numbers" (n) contains only positive values. They are used in numerical ordering and counting.

They are {N=0,1,2,3,4,......}

Here, x+6=5

Only an integer can meet the condition from the given parameters. This is because an integer has two possible values: positive and negative.

i.e

By adding (-6) to both sides, we have:

x+6-6=5-6

The graph of the quadratic equation is shown in the image attached below.

In accordance with algebra fundamental theorem, we can construct a quadratic equation by knowing the locations of at least three points on Cartesian plane. Herein we find a quadratic equation in vertex form, whose formula is described below:

y - k = C · (x - h)²

Where:

By using this expression, we can find the locations of the vertex and intercepts of the parabola. Now we proceed to find all the required information:

Vertex

y = (x + 5)²

(h, k) = (- 5, 0)

x-Intercepts

(x + 5)² = 0

x = - 5

y-Intercept

y = (0 + 5)²

y = 25

Another point

x = - 1

y = (- 1 + 5)²

y = 4²

y = 16

Finally, we mark the three points on the Cartesian plane and pass a curve through them. The result is shown in the image attached below.

Explanation- Did the maths

The number of pounds of steak she buys is 0.82 pounds

From the question, we have the following parameters:

3.5 pounds of steak = $36.75

From the question, we understand that

Hannah spent $8.61 on steak

This means that

x pounds = $8.61

So, we have the following system of equations

3.5 pounds of steak = $36.75

x pounds = $8.61

Cross multiply in the above equation

So, we have

36.75 * x = 3.5 * 8.61

Divide both sides of the equation by 36.75

x = 3.5 * 8.61/36.75

Evaluate the quotient

x = 0.82

Hence, the number of pounds of steak she buys is 0.82 pounds

The linear equation that passes through (-1, 8) and (5,-2) is:

y = (5/3)*x + 29/3

A general linear equation in the slope-intercept form is:

y = a*x + b

Where a is the slope, and b is the y-intercept.

If we know that this line passes trhough the points (-1, 8) and (5, -2) then we can write the slope as:

a = (-2 - 8)/(5 + 1) = -10/6 = 5/3

Then we can write:

y = (5/3)*x + b

Now to find the value of b we can replace the values of one of the points in the line, if we use (-1, 8) we will get:

8 = (5/3)*-1 + b

8 + 5/3 = b

24/3+  5/3 = b

29/3 = b

We conclude that the linear equation is:

y = (5/3)*x + 29/3

The solution to the equation is x = 38

Expressions are mathematical statements that are represented by variables, coefficients and operators

The equation is given as

1/3|x - 8| = 10

Multiply through by 3

So, we have

|x - 8| = 30

Remove the absolute bracket

So, we have

x - 8 = 30

Add 8 to both sides of the equation

So, we have

x = 38
