F(x)=2x^2+7x-5+g(x)=-8x^2-3x+5

what is g(x) + f(x)

Answers

Answer 1

Answer: f(x) = 2x² + 7x - 5
g(x) = -8x² - 3x + 5

g(x) + f(x)
-8x² - 3x + 5 + 2x² + 7x - 5
-8x² + 2x² - 3x + 7x + 5 - 5
-6x² + 4x + 0

-2x(3x - 2)

If we wanted to know how high a 5th-grade student could jump, how many students would be reasonable to test? 5, 12, 30, or 200.please help

Answers

200 students would be reasonable to test because you can average the score more easily.

What is average in maths?

In plain English, an average is indeed a single number chosen to represent a group of numbers; it is often the sum of the values divided by the number of numbers in the group. The average of a integers 2, 3, 4, 7, or 9 is, for instance, 5. An average could be another statistic like the median or mode depending on the situation.

here, we have,

Because the mean would be greater if the personal incomes of a few billionaires were included, the median—the amount below which 50% of personal incomes fall and over which 50% of personal incomes rise—is sometimes used to represent the average personal income.

It is advised to avoid to use the word "average" while addressing central tendency measurements because of this.

If we wanted to know how high a 5th-grade student could jump, 200 students would be reasonable to test because you can average the score more easily.

Therefore, 200 students would be reasonable to test because you can average the score more easily.

The right amount to test would be 30.

200 is to many kids and 12 is not enough.

Gerard ran out of tile for his patio. The width of the remaining area is 2 and two ninths feet. The length of the remaining area is 7 feet. How much does Gerard have left over to tile. I don't get it my brain is not working please help me

Answers

Gerard has left 15.33 square feet area to tile.

The width of the remaining area = $2(2)/(9)$ feet

The width of the remaining area = $(20)/(9)$ feet

The length of the remaining area = 7 feet

What is the area of a rectangle?

The area of a rectangle is the product of length to width.

So, the remaining area = $(20)/(9) *7$

The remaining area = $(140)/(9)$ square feet

The remaining area = 15.33 square feet

So, Gerard has left to tile = 15.33 square feet

Thus, Gerard has left 15.33 square feet area to tile.

To get more about rectangles visit:

brainly.com/question/25292087

To figure this out, you have to use the formula for area. A=l×w where l is the length, and w is the width.

l = 2 2/9 ft.

w = 7 ft.

First, we should put 2 2/9 into decimal form, as it'll make it easier to
multiply.

2/9 = 0.22

So, 2 2/9 = 2.22

A = l × w

A = 2.22 × 7

A = 15.54

The area Gerard has left over to tile is 15.54 square feet.

Answer:

Both Jules' and Lauren's equations are correct because they have slopes that are the negative reciprocal of the slope of the given line, making them perpendicular to the given line.

Step-by-step explanation:

Let's reevaluate the equations based on the corrected given line equation:

$\sf y - 2 = (1)/(5)(x - 3)$

The given line equation is in point-slope form: $\sf \boxed{\sf y - y_1 = m(x - x_1)}$ , where m is the slope.

Given line equation: $\sf y - 2 = (1)/(5)(x - 3)$

While comparing, we get

$\textsf{The\underline{ slope (m) }of the given line is }(1)/(5)$

For a line to be perpendicular to the given line, its slope must be the negative reciprocal of the slope of the given line.

The negative reciprocal of $\sf (1)/(5)$ is $\sf -5.$

Now let's check the slopes of the equations provided by Jules and Lauren:

1. Jules' equation: $\sf y = -5x + 1$

The slope of Jules' equation is -5, which matches the negative reciprocal of the slope of the given line.

2. Lauren's equation: $\sf y = -5x + 7$

The slope of Lauren's equation is also -5, which again matches the negative reciprocal of the slope of the given line.

Both Jules' and Lauren's equations have a slope of -5, which is the negative reciprocal of the slope of the given line $(1)/(5)$ .

Therefore, both equations are correct and satisfy the condition of being perpendicular to the given line $\sf y - 2 = (1)/(5)(x - 3)$

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

$y-2=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{5}}(x-3)\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\n \cline{1-1} \n y-y_1=m(x-x_1) \n\n \cline{1-1} \end{array} \n\n[-0.35em] ~\dotfill$

$\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{ \cfrac{1}{5}} ~\hfill \stackrel{reciprocal}{\cfrac{5}{1}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{5}{1} \implies -5}}$

so ANY line that is perpendicular to that equation above, will have a slope of -5, so any of these are all perpendicular to it

$\begin{array}{llll} \stackrel{ Jules }{y=-5x+1} \n\n\n \stackrel{ Lauren }{y=-5x+7} \n\n\n y=-5x+999999999 \n\n\n y=-5x-93789 \end{array}\hspace{5em} \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\n \cline{1-1} \n y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \n\n \cline{1-1} \end{array}$

Twenty-two is what percent of 55?A.
22%

B.
40%

C.
250%

D.
50%

Answers

Answer:

Option B is correct.

Twenty-two is 40 percent of 55

Step-by-step explanation:

Let x be the number.

As per the statement:

Twenty-two is x percent of 55

Solve for x:

Twenty-two is x percent of 55

"of" means multiply

⇒ $22 = (x)/(100) * 55$

Divide both sides by 55 we get;

$(22)/(55) = (x)/(100)$

Simplify:

$(2)/(5) = (x)/(100)$

Multiply both sides by 100 we have;l

$x = (2)/(5) * 100$

Simplify:

x = 40%

Therefore, Twenty-two is 40 percent of 55

To find the percentage
that 22 is for the actual number 55 = (22/55) * 100
      = (2/5) * 100
      = 2 * 20
      = 40 percent
So the correct option among all the options given in the question is option "B".Most of the information’s that are required for solving thisproblem is already given in the question. I hope the procedure for solving theproblem is also clear for you to understand. In future you can always use thismethod for solving similar problems.
