Answer:

x = 27

Step-by-step explanation:

because the angles are on a line that means they add up to 180

18 + x + 5x = 180

then combine like terms

18 + 6x = 180

then you subtract 18 from both sides

6x = 162

lastly divide both sides by 6

x = 27

I am going to assume that leg a:

  ⇒ is the horizontal distance between the house and the gas station

     ⇒ Distance for leg a: 6 miles

I am also going to assume that leg b

  ⇒ is the vertical distance between the house and gas station

     ⇒ Distance for leg b: 5 miles

Thus using the Pythagorean theorem: [tex]a^2+b^2=c^2[/tex]

   ⇒ (look at diagram attached for further explanation)

Answer: [tex](2, 2), (6, 4), (8, 10), (9, 28)[/tex]

Step-by-step explanation:

The first four ordered pairs using the two sequences are:[tex](2, 2), (6, 4), (8, 10), (9, 28)[/tex]

The first rule is to add 10, then divide by 2 starting from 2

Add/Divide:

[tex]10=2+10=12[/tex]

[tex]2=12[/tex]÷[tex]2=6[/tex]

Add/divide again:

[tex]10=6+10=16[/tex]

[tex]2 = 20[/tex]÷[tex]2 = 10[/tex] [tex]2=16[/tex]÷[tex]2=8[/tex]

Add/divide again:

[tex]10=8+10=18[/tex]

[tex]2=18[/tex]÷[tex]2=9[/tex]

Answer:

B. acute, isosceles

Step-by-step explanation:

The two small lines intersecting the two sides stand for congruency.

Two sides are congruent, so this is an isosceles triangle.

None of the angles here are greater or equal to 90 degrees, so it is an acute triangle.

Please mark brainliest!

Answer:

B. Acute, isosceles

Step-by-step explanation:

Angles can be classified by both their sides and angles. There are 3 classification for each measurement, making 6 total classifications. This includes acute, right, and obtuse for angles and isosceles, scalene, and equilateral for sides.

Sides

The tic marks on 2 sides on the side show that they are congruent. Any triangle that has 2 congruent sides is classified as isosceles.

An additional fact is that the angles opposite of the congruent sides are also congruent. This information is not pertinent to this question, but might be useful in the future.

Angles

A triangle's classification for its angles is always based on the largest angle in the triangle. In this case, the largest angle is an acute angle. Remember that an acute angle is less than 90 degrees. This means that the triangle is acute.

Answer:

  an = 40 -7(n -1)

Step-by-step explanation:

The given sequence has terms with a common difference, so it is an arithmetic sequence. The formula for the general term of an arithmetic sequence applies:

  an = a1 +d(n -1)

__

The first term of the given sequence is ...

  a1 = 40

The common difference for this sequence is ...

  d = 33 -40 = -7

Using these values in the equation for the n-th term, we have ...

  an = 40 -7(n -1) . . . . . explicit formula for the n-th term

The volume of the cylinder is 471.43 cm³.

The volume of the cone is 157.14 cm³.

The volume of the sphere is  523.81 cm³.

The shape that would hold the most volume is the sphere.

A cylinder is a three-dimensional object. It is a prism with a circular base.

Volume of a cylinder = πr²h

Where:

π = 22/7

r = radius

22/7 x 5² x 6 = 471.43 cm³

Volume of a cone = 1/3 x volume of a cylinder

1/3 x  471.43 cm³ = 157.14 cm³

What is the volume of a sphere?

Volume of a sphere = 4/3 x pi x r³

4/3 x 5³ x 22/7 = 523.81 cm³

Answer:

  a)  f'(x) = 12x

  b)  -120

  c)  36

  d)  y = 36x -55

Step-by-step explanation:

The derivative is the limit of the average slope on an interval as the interval size approaches zero. The equation for a tangent line is conveniently written in point-slope form when the tangent point and the derivative there are known.

__

The derivative is ...

  [tex]\displaystyle f'(x)=\lim_{h\to 0}{\dfrac{f(x+h)-f(x)}{h}}=\lim_{h\to 0}\dfrac{(6(x+h)^2-1)-(6x^2-1)}{h}\\\\=\lim_{h\to 0}\dfrac{(6x^2+12xh+6h^2-1)-(6x^2-1)}{h}=\lim_{h\to 0}\dfrac{12xh+6h^2}{h}=\lim_{h\to 0}(12x+6h)\\\\\boxed{f'(x)=12x}[/tex]

__

  f'(-10) = 12(-10) = -120

__

  f'(3) = 12(3) = 36

__

The point of tangency is ...

  (3, f(3)) = (3, 6·3² -1) = (3, 53)

The slope there was found in part (c) to be 36. So, the point-slope equation for the tangent line can be written ...

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

  y -53 = 36(x -3) . . . . equation of the tangent line at (3, 53)

This equation can be rearranged to slope-intercept form:

  y = 36x -55 . . . . . add 53 and simplify
