if f(x) = 2x^2 +1 and g(x) = 3x-2 what is the value of f(g(x))

Answers

Answer:

18x² - 24x + 9

Step-by-step explanation:

To find f(g(x)), substitute x = g(x) into f(x) , that is

f3x - 2)

= 2(3x - 2)²+ 1 ← expand factor using FOIL

= 2(9x² - 12x + 4) + 1 ← distribute parenthesis by 2

= 18x² - 24x + 8 + 1

= 18x² - 24x + 9

Find the 75th term of the arithmetic sequence
16, 15, 14,

Answers

Answer:

[tex]a_{75}=-58[/tex]

Step-by-step explanation:

This is an arithmetic sequence:

[tex]a_n=a_1+(n-1)d[/tex]

where d is the common difference and n is the index of any given term.

For the given sequence, the common difference is -1:

[tex]15-16=-1\\14-15=-1[/tex]

Knowing both the common difference and the first term, you can write the equation for this sequence:

[tex]a_n=16+(n-1)(-1)[/tex]

Then you can use that equation to find the 75th term:

[tex]a_{75}=16+(75-1)(-1)\\a_{75}=16+(74)(-1)\\a_{75}=16-74\\a_{75}=-58[/tex]

Jacoby made and sold x candy bars in one week. His profit, P, in dollars is calculated using the formula P = R-C

where R represents his revenue and C represents his costs. If R = 3x^2 – x+ 6 and C = -7x^2– 7x + 2. what is

the expression that represents his profit in dollars?

Answers

Answer:  P = 10x^2 +6x + 4

Step-by-step explanation:

P = R-C

R = (3x^2 - x + 6)

C = (-7x^2 -7x + 2)

P = (3x^2 - x + 6) - (-7x^2 -7x + 2)

P = 3x^2 - x + 6 + 7x^2 +7x - 2

P = 10x^2 +6x + 4

You are given the domain and range ( the numbers in each oval):

If There is more than one arrow connected to a number, that number is listed the same amount

Domain (-4,0,6,6)

Range (12,18,18,40)

To be a function each input value ( Domain) can only have one output value (range)

Because the 6 has two different outputs ( 12, 18) this is not a function.

Answer:

The input 6 (domain) leads to two outputs thus it is not a function.

Step-by-step explanation:

-k is the same as -1k so you can just solve it like that. Also, when adding terms with variables you just add the number in front (if they have the same variable). So -1k + 3k = 2k. Pretty much the same as -1 + 3, you just add a variable..

What are the coordinates of the point on the directed line segment from (-4,-1) to (6,4) that partitions the segment into a ratio of 3 to 2?

Answers

Using proportions, it is found that the coordinates of the desired point are (2,2).

The first point is A(-4, -1).The second point is B(6, 4).The desired point is C(x,y).

The point C partitions the segment AB into a ratio of 3 to 2, hence:

[tex]C - A = \frac{3}{5}(B - A)[/tex]

This proportion is applied using both the x and y coordinates of the points, hence:

[tex]x - (-4) = \frac{3}{5}[6 - (-4)][/tex]

[tex]x + 4 = 6[/tex]

[tex]x = 2[/tex]

[tex]y - (-1) = \frac{3}{5}[4 - (-1)][/tex]

[tex]y + 1 = 3[/tex]

[tex]y = 2[/tex]

The coordinates of the desired point are (2,2).

Answers

Given that
The length of the rectangle 4cm and the breadth is 3cm
Area of rectangle= length * breadth
Area= 4*3
= 12cm^2
Hope it helped

Step-by-step explanation:

We first calculate the lenght of the diameter, that is also the lenght of the hypotenuse of the right triangle shown in the figure:

d = [tex]\sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex] cm

The radius of the circle will be half of the diameter: r = d/2 = 2.5 cm

The area of the circle will be: Acircle = pi * r^2 = pi * 6.25 cm^2 = 19.6 cm^2 (circa).

Now from the area of the circle we subtract the area of the square:

Asquare = 4cm * 3cm = 12cm^2

A shaded = Acircle - Asquare = 19.6 cm^2 - 12cm^2 = 7.6 cm^2

Since the exponent is uneven you can take 2 and 1 and add them to the x's multiply to get 3 and since 9 is a perfect square you can square root it and get 3 which you put on both sides. Since the 9 is negative one of the symbols have to be negative, usually put in the second parenthesis.

A guidance counselor wants to determine if there is a relationship between a student’s number of absences, x, and their grade point average (GPA), y. He collects data for 15 randomly selected students and determines the value for s was 0.67.

Answers

The interpretation of the value of s being 0.67 is that: the typical distance between the observed grade points and predicted grade points was about 0.67 points.

The given parameters are:

n = 15s = 0.67

Variable s

In regression, the variable s represents the average distance that the observed values fall from the regression line

The grade points

In this case, we have:

The observed grade points and The predicted grade points

Hence, 0.67 represents the typical distance between the observed grade points and predicted grade points.

New guidelines were recently published by the U.S. Department of Agriculture (USDA) to improve the way people eat. Recommendations include lowering salt intake, eating less sugar and saturated fats, and eating more fruits and vegetables. These guides have come out every 5 years, but though they are developed by reputable scientists, the public virtually ignores them. Countless studies have linked overeating and sedentary lives with multiple diseases and increased medical costs. Even with high-profile figures like Michelle Obama leading the fight for healthier lifestyles, the old habits die hard. The need to shift to healthier eating is more urgent now than ever. Weight problems are epidemics in the United States, as is the equally pressing problem of undernourishment. For example, people today eat far too much salt. This salt addiction has been proven to increase the risk for heart disease and stroke, as well as other costly and life-threatening illnesses. The new guidelines give specific recommendations regarding how much daily salt is healthy. However, it's doubtful whether Americans will heed the advice. They'd rather watch cable TV and eat French fries than make changes that would likely prolong their lives. Thankfully, the USDA has become proactive in changing the way we Americans eat. Most people are familiar with the famous food pyramid the agency developed years ago, showing the food groups and servings of each group. However, the agency's guidelines go far beyond the colorful posters hanging in schools across the nation. School meal programs are impacted by the document, as are decisions about the labeling of foods and how foods are marketed to young people. In particular, by using the guidelines to target school breakfast and lunch programs, the USDA hopes to make healthy foods an easy alternative for kids. Clearly, adults cannot be counted on to make healthy eating a priority. With the USDA's help, school kids will get started early on a lifetime of good diet habits.The author of this selection feels A. that Americans don't want to change their eating habits. B. that breakfast is the most important meal of the day. C. that people will wise up and start following the USDA guide. D. that kids will reject the healthy school lunch options.
