help please. I will give brainliest to first answer.

Answer:

x² + 2x - 6

Step-by-step explanation:

= f(x) + g(x)

= (2x + 1) + (x² - 7)

= 2x + 1 + x² - 7  

= 2x - 6 + x²  

= x² + 2x - 6

good luck, i hope this helps :)

Step-by-step explanation:

Answer: Approximately 49 degrees

A slightly more accurate angle value is about 49.458398 degrees.

======================================================

Explanation:

Draw a right triangle as shown in the diagram below. The horizontal leg is 13 ft and the hypotenuse is 20 ft. The angle between these two sides is what we want to find.

With this reference angle, the adjacent side is 13 and the hypotenuse is 20. We use the cosine ratio to tie the sides together with this angle.

Let x be the unknown angle.

cos(angle) = adjacent/hypotenuse

cos(x) = 13/20

cos(x) = 0.65

x = arccos(0.65)

x = 49.4583981264954

x = 49

I'm rounding to the nearest whole number since the given values (13 and 20) are also whole numbers. If your teacher provides other rounding instructions, then be sure to follow that of course.

The angle of elevation is roughly 49 degrees. Make sure your calculator is in degree mode. The notation "arccos" stands for "arccosine" and it's the same as inverse sine.

My brother, they would add to 180 :D

You can see, QTS is an obtuse angle, and the PTQ is smaller, but no matter what, if you add them, they will always add up to 180

Answer:

  12.  median: AD; altitude: CE; midsegment: none

  13.  x = 2

Step-by-step explanation:

12. The median joins a vertex with the midpoint of the opposite side. Point D is identified as the midpoint of BC, so AD is the median.

An altitude is a segment from a vertex that is perpendicular to the opposite side. CE is an altitude of this triangle.

A midsegment joins midpoints of adjacent sides of the triangle. Only one midpoint (D) is identified in this triangle, so no midsegment can be named.

Additional comment: BF is an angle bisector. Perhaps that is what is intended in part (c). You may want to report this question to your teacher.

13. The base segment is twice the length of the midsegment:

  2(5x -3) = x +12

  10x -6 = x +12 . . . . . eliminate parentheses

  9x = 18 . . . . . . . . . .  add 6-x

The answer is "(0.782, 0.818)".

Step-by-step explanation:

computing the sample proportion:

[tex]p=\frac{x}{n}= \frac{1,600}{2000}=0.80 \\\\[/tex]

[tex]\text{Computing the} \ 95\% \ \ C.I \\\\[/tex]

[tex]C.I= p \pm Z_{\frac{\alpha}{2}}\sqrt{\frac{P(1-p)}{n}}[/tex]

     [tex]= 0.80 \pm 1.96 \sqrt{\frac{0.80(1-0.80)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.80(0.20)}{2000}} \\\\= 0.80 \pm 1.96 \sqrt{\frac{0.16}{2000}} \\\\ = 0.80 \pm 1.96 \sqrt{0.00008} \\\\=0.80 \pm 0.18 \\\\= (0.782, 0.818)[/tex]

conclusion:

Since the interval calculation contains higher values than 75 percent of its union membership, the merger proposal is likely to pass.

Answer:

the 9 in the tenths place is 10 times bigger than the one in the hundredths place

Step-by-step explanation:

The value of the 9 in the tenth place is "10 times" the value of the 9 in the hundredth place.

Place value strategies are defined as math strategies that use to assist you in resolving your elementary math problems, using your place values, such as tens and hundreds.

The decimal we are examining is 3.9928.

The 9 in tenth place has a value of 0.9.

The value of 9 in the hundredth place is 0.09

The fraction of the 9 in the tenth place is now the 9 in the hundredth place.

To get this, simply multiply the value of 9 in the hundredth place by the value of 9 in the tenth place.

Mathematically, that would be;

0.09/0.9 = 0.1 = 1/10

This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place

So you can complete the statement by dragging and dropping "10 times" into the response area.

Answer:

3 meters

Step-by-step explanation:

A sphere is a three-dimensional geometrical object.

Let r denotes radius of a sphere.

Area of a sphere = [tex]4 \pi r^2[/tex]

Volume of a sphere = [tex]\frac{4}{3}\pi r^3[/tex]

As a sphere which area (in square meters) is equal to its volume (in cubic meters) ,

[tex]4\pi r^2=\frac{4}{3}\pi r^3\\\\ r^2=\frac{r^3}{3}\\\\\frac{r^3}{r^2}=3\\\\[/tex]

r = 3 meters

Answer:

around  571% or to be more exact, around 571.15384615%

Step-by-step explanation:

468 = 100%

2673 = ?

2673/468 = 297/52 = 5.71153846...≈5.7

468 * 2673/468 = 100%* 2673/468

2673 ≈571.15384615%

% ≈ 571%

Answer:

Amazing but what is the question

Step-by-step explanation:

Answer:

32 minutes

Step-by-step explanation:

There are 60 seconds in a minute

That means we will need to know how many feet he walks in a minute

So we would do 3 x 60 which equals 180 so he walks 180 ft per miute

Now we need to figure out how many minutes it took for him to walk 5760 ft.

So we would do 5760 ÷ 180 which equals 32

So the aswer is 32 minutes for him to walk 5760 ft.

Answer:

  12.9 square yards

Step-by-step explanation:

The base is an equilateral triangle, so we can assume that the three faces have the same dimensions. Each of those face triangles has an area of ...

  A = 1/2bh

  A = 1/2(3 yd)(2 yd) = 3 yd²

The base area is computed using the same formula and the given height:

  A = 1/2(3 yd)(2.6 yd) = 3.9 yd²

Then the total surface area is that of the base and the three faces:

  SA = (3.9 yd²) + 3(3 yd²) = 12.9 yd² . . . total surface area

Answer:

shorter side = 7 in

longer side = 12 in

Step-by-step explanation:

Let w = width

then w + 5 = length

The perimeter of the rectangle = 2 widths + 2 lengths.

So, w + w + w + 5 + w + 5 = 38  or 2w +2(w + 5) = 38 are two ways to write the equation to solve the problem.

Now 4w + 10 = 38

4w = 28

w = 7

w + 5 = 7 + 5 = 12

shorter side = 7 in

longer side = 12 in

Check:  7 + 7 + 12 + 12 = 38 = perimeter
