Answer:

Step-by-step explanation:

Arithmetic sequence

The terms of an arithmetic sequence have common difference. If the missing term is x, then the difference between terms is the same:

  x -250 = 10 -x

  2x = 260 . . . . . . add 250+x to both sides

  x = 130 . . . . . . . . divide by 2

The missing term of an arithmetic sequence is 130.

(the common difference is -120)

__

Geometric sequence

The terms of a geometric sequence have a common ratio. If the missing term is x, then the ratios between terms are the same:

  x/250 = 10/x

  x^2 = 2500 . . . . . . . multiply both sides by 250x

  x = ±√2500 = ±50 . . . take the square root

The missing term of a geometric sequence is +50 or -50.

(the common ratio is ±1/5)

Answer:

cosA = [tex]\frac{8}{17}[/tex]

Step-by-step explanation:

Using the identity

cosA = [tex]\frac{1}{secA}[/tex] = [tex]\frac{1}{\frac{17}{8} }[/tex] = [tex]\frac{8}{17}[/tex]

Answer:

8/17

Step-by-step explanation:

sec A = Hypotenuse/ Adjacent = 17/8

cos A = Adjacent / Hypotenuse = 8/17

Answer:

Step-by-step explanation:

Her car doing a 360 means that the car turned in a manner akin to going round a full circle. This is because, she was moving on an icy way. Ice have been known to be slippery, and thus, stepping on the brakes unexpectedly would have made the car tilt a bit, which then increased to turning sideways, and an eventually full circle turning. This full circle turning is what is being referred to as 360

Answer:

square root of 2

Step-by-step explanation:

Answer:

A 10.28in

Step-by-step explanation:

Find the perimeter of the circle first. Because there are two half-circles, you can just find the circumference of one whole circle. 2πr is the formula. r is the radius. The circumference of the circle is 2π or 6.28.

Then add the two sides of the square. It is 2+2=4. Add 6.28 and 4.

Answer:

18.9

Step-by-step explanation:

perimeter of a trapezoid is base + base + side + side (p = a + b + c + d)

adding up each of the sides gives you 18.9

Answer: 140cm²

Step-by-step explanation:

Perimeter of a rectangle is calculated as: = 2(length + width)

where,

Length = x+4

Width = x

Therefore, perimeter = 2(length + width)

2(x + x+4) = 48

2(2x + 4) = 48

4x + 8 = 48

4x = 48 - 8.

4x = 40

x = 40/4

x = 10cm

The other side = x+4 = 10+4 = 14cm

Area = length × width

Area = 10cm × 14cm

Area = 140cm²

Answer:

B

Step-by-step explanation:

I am assuming that this ball is a perfect sphere.

The volume of a sphere is [tex]\frac{4}{3} *\pi *r^3[/tex]

We have the diameter, and in order to find the radius, we just have to divide by 2. 6/2=3. Now, we have to plug in the 3 to the equation.

[tex]\frac{4}{3} *\pi *3^3[/tex]

3 cubed is 27, so now we have [tex]\frac{4}{3} *\pi *27[/tex]

27*4/3*pi=36pi

Step-by-step explanation:

2 in/16mi = 19 in/x mi

152 mi

Answer:

16 miles = x miles

(1/2) inch 2 3/4 inches

x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles

(1/2)

Step-by-step explanation:

As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.

Answer:

B. [tex] (2, -\frac{5}{2}) [/tex]

Step-by-step explanation:

Given:

(2, 4) and (2, -9)

Required:

Midpoint of the vertical line with the above endpoints

Solution:

Apply the midpoint formula, which is:

[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]

Where,

(2, 4) = (x_1, y_1)

(2, -9) = (x_2, y_2)

Plug in the values into the equation:

[tex] M(\frac{2 + 2}{2}, \frac{4 + (-9)}{2}) [/tex]

[tex] M(\frac{4}{2}, \frac{-5}{2}) [/tex]

[tex] M(2, -\frac{5}{2}) [/tex]

Answer:

62 feet. looked it up.

Step-by-step explanation:

Have a great day! :)

We know a or b != 0

but a-b==0 so both are the same unknown number

b/a must = 1

so

a/b is equivalent to b/a as a/b=1 as well.

So the last answer choice.

True, (x-2) is a factor of the polynomial 4x^2-6x-4. Option A is correct.

A polynomial is an algebraic statement made up of variables and coefficients.

Variables are sometimes known as unknowns. We can use arithmetic operations like addition, subtraction, and so on. However, the variable is not divisible.

Given equation;

[tex]\rm 4x^2-6x-4[/tex]

The factors of the given equation:

2(2x+1)(x−2)

True, (x-2) is a factor of the polynomial 4x^2-6x-4.

Hence option A is correct.

Answer: I am truly sorry for doing this.

Step-by-step explanation:

Answer:

22.44 cm^2

Step-by-step explanation:

There's four triangles and one square so lets start with the triangles.

2.24×3÷2=3.36

That's the area of one triangle, there's four so:

3.36×4=13.44

Then the square!

3×3=9

13.44+9=22.44 cm^2

I'm not sure if this is the standard way since I didn't learn about pyramids so I used the area stuff, so sorry if its not correct.

Have a nice day!
