Answer:
-12
Step-by-step explanation:
F(T)=2(1×+1)
2(1×+1)= x2 + 2, and since we were trying to find what f is, we know know f=2 because of the equation 2(1×+1), so, 2(-6)= -12

Write the equation of the line in slope-intercept form The line is parallel to y + x =3 and passes through the point (-12, 0)
Step-by-step explanation:
The line is parallel to y + x =3
=> y = -x+3
the slope = -1
passes (-12, 0)
the equation would be :
y-0 = -1(x+12)
y = -x -12

Super easy please help
To find the x-intercept, you need to see where the line intersects the x-axis, the horizontal line with numbers on it. The line intersects the x-axis at (2, 0). Therefore, the x-intercept is (2, 0).
To find the y-intercept, you need to see where the line intersects the y-axis, the vertical line with numbers on it. The line intersects the y-axis at (1, 0). Therefore, the y-intercept is (1, 0).
There are two ways to find the slope. The easiest one in my opinion is rise over run, but you can also use an equation too. I am going to be showing you the rise/run method, but you can also ask if you want the equation method as well. First of all, the line goes to the left, not the right, so we know that the slope is going to be negative. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x). All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run). I am going to choose point (1, 0) if I go up by 2 and over by 4, I'll get to the point (-4, 3) that also lands on the line. 2/4 is 1/2. Therefore, the slope is -1/2.
I hope this helps! Let me know if I got something wrong.

Use the definition mtan=lim
(a) mtan refers to the slope of the tangent line. Given f(x) = 9 + 7x ², compute the difference quotient:
[tex]\dfrac{f(x+h)-f(x)}h = \dfrac{(9+7(x+h)^2)-(9+7x^2)}h = \dfrac{(9+7x^2+14xh+7h^2)-9-7x^2}h = \dfrac{14xh+7h^2}h[/tex]
Then as h approaches 0 - bearing in mind that we're specifically considering h near 0, and not h = 0 - we can eliminate the factor of h in the numerator and denominator, so that
[tex]m_{\rm tan} = \displaystyle \lim_{h\to0}\frac{f(x+h)-f(x)}h = \lim_{h\to0}\frac{14xh+7h^2}h = \lim_{h\to0}(14x+7h) = 14x[/tex]
and so the slope of the line at P (0, 9), for which we take x = 0, is 0.
(b) The equation of the tangent line is then y = 9.

Please help with geometry
Answer:
m∠2 = 68°, m∠3 = 112°, m∠4 = 68°
Step-by-step explanation:
m∠3 = m∠1 ( Vertically opposite angles )
m∠3 = 112°
m∠2 = 180 - m∠1
m∠2 = 180 - 112
m∠2 = 68°
m∠4
Solution 1:
m∠4 = m∠2 (Vertically opposite angles)
m∠4 = 68°
Solution 2:
m∠4 = 180 - m∠1
m∠4 = 180 - 112
m∠4 = 68°

Answer:
$42,918
Step-by-step explanation:
There are basically a couple ways to do this
First way:
46,000 x 0.067 = 3,082
46,000 - 3,082 = 42,918
Second way
46,000 x (1 - 0.067)
46,000 x 0.933 = 42,918
Either way works; just use which one you prefer

One end of a wire is attached to the top of a 24-foot pole; the other end of the wire is anchored to the ground
18 feet from the bottom of the pole. If the pole makes an angle of 90° with the ground, find the length of the
wire.
Answer:
30 feet
Step-by-step explanation:
We can use Pythagorean theorem for this question because the pole and the wire that is anchored to the ground forms an right triangle because the pole makes an angle of 90 degrees.
One side of the right triangle formed is equal to 24 feet, and because the wire that is anchored to the ground is 18 feet from the bottom of the pole, another side is 18 feet.
Pythagorean theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]. With a and b being the sides of the right triangle and c being the hypotenuse. In this problem, the length of the wire is equal to the hypotenuse of the triangle.
a=24 and b =18. 24 squared is equal to 576, and 18 squared is equal to 324. We add 576 and 324, which is 900. This means that [tex]c^{2}[/tex] =900. To find c, we find the square root of 900, which is 30. Therefore, the length of the wire is 30 feet.
Answer:
30 feet
Step-by-step explanation:
1. The 24-foot pole and the 18 feet from the bottom of the pole form a right angle, meaning that when you add the length of the wire, a right triangle forms.
2. "24-foot pole" is the height, and "18 feet from the bottom of the pole" is the base. The length of the wire is the hypotenuse.
3. To find the hypotenuse of a right triangle, we can use the Pythagorean theorem to solve it: [tex]a^2 + b^2 = c^2[/tex], where a = leg of triangle, b = leg of triangle, and c = hypotenuse (or in this case, the wire).
4. Now, let's apply the formula:
[tex]18^2 + 24^2 = c^2[/tex]Step 1: Simplify both sides of the equation.
[tex](18*18)+(24*24)=c^2[/tex] [tex]324 + 576 = c^2[/tex] [tex]900 = c^2[/tex]Step 2: Take square root of both sides.
[tex]\sqrt{900} =\sqrt{c^2}[/tex] [tex]30 = c[/tex]Step 4: Check if solution is correct.
[tex](18*18)+(24*24)=(30*30)[/tex] [tex]324 + 576 = 900[/tex] [tex]900 = 900[/tex]Therefore, the length of the wire is 30 feet.

After adding the ice, they noticed the soup became watery and did not taste very good. They wanted to figure out a way to quickly cool the soup but not water it down. They had two separate ideas. The older brother wanted to place the entire bowl into the freezer and let it sit for 2 minutes. The younger brother wanted to divide the soup into two smaller bowls and then place both of them in the freezer for 2 minutes. Describe how you could use science ideas and tools to decide which brother has the better method of cooling their soup. As you explain your answer, talk about energy and explain how it moved. You can include a diagram, but it must be explained with words.
Answer: This is your opinion and is probably graded for you stating your opinion.
Step-by-step explanation:
If you use the older brothers method, your soup would not cool down as fast in 2 minutes, because it's a lot of soup in one bowl, just like how a cup of water would freeze faster than a whole lake. If you want your soup to completely cool down in 2 minutes, use the younger brothers method.

if abc~ dec , what is the length of de? Please help
Answer:
B) 12
Step-by-step explanation:
Given:
ΔABC ~ ΔDEC
AB ~ DE
AC ~ DC
BC ~ EC
We will just use ratios and substitute DE as x:
[tex]\frac{AB}{AC} =\frac{DE}{DC} \\\\\frac{16}{20} =\frac{x}{15} \\\\20x=240\\\\x=\frac{240}{20} \\\\x=12[/tex]
DE = 12
The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. If two triangles are similar, then the ratio of the corresponding sides will remain constant.
The triangles ABC and DEC are similar triangles. Then the ratio of the corresponding sides will be the same.
DE/AB = CD/AC
From the diagram, AB = 16, AC = 20, and CD = 15. Then the measure of the side DE will be given as,
DE/16 = 15/20
DE/16 = 0.75
DE = 16 x 0.75
DE = 12
The measure of the side DE of the triangle DEC will be 12. Then the correct option is B.
