Step-by-step explanation:

Answer:

A

Step-by-step explanation:

When x < 1, y = 1, which is a horizontal line. This eliminates the last 2 options because the red line (which represents x < 1) is not a horizontal line. However, if we look at the second option, we see that the red line is y = 2, not y = 1, and therefore the answer is A. Hope this helps!

Answer:

The relationship between [tex]\angle 1[/tex] and [tex]\angle 8[/tex] are Alternate Exterior Angles.

Step-by-step explanation:

Alternate Exterior Angles, are pair of angles that lie on the outside of the traversal and lie on the opposite sides.

The required name of the relationship between 1 and 8 is alternate exterior angles

The correct option is (c)

When a transversal cut the pair of parallel lines then the alternate exterior angles are congruent.

Consider the given pair of parallel lines and transversal

we have

angel 1 and 5 are corresponding angles

angle 2 ad 6 are corresponding angles

angle 1 and 8 are alternate exterior angle

angle 2 and 7 are also alternate exterior angle

Therefore the correct option is (c)

This is the conclusion to the answer.

Okay, so for this, you need to know that (g°f)(x) = g(f(x))

in order words, we are using the f(x) equation as X for the g(x) equation..

[tex]\frac{ x^{2} +5 + 5}{ x^{2} +5}[/tex] = [tex]\frac{x^{2}+10}{x^{2}+5}[/tex]

Now, we just plug in -3 for X

Answer:

Volume, [tex]V=889.7\ m^3[/tex]

Step-by-step explanation:

From the attached figure,

Radius of shape is 5 m

Height of the cylindrical part is 8 m

It is required to find the volume of the given shape. The volume of the given object is equal to the sum of volume of cylinder and volume of hemisphere. So,

[tex]V=\pi r^2h+\dfrac{2}{3}\pi r^3\\\\V=3.14\times (5)^2\times 8+\dfrac{2}{3}\times 3.14\times 5^3\\\\V=889.7\ m^3[/tex]

So, the volume of the figure is [tex]889.7\ m^3[/tex].

You need to divide 3 on both sides

The correct first step to solve the equation 3x = 44 is to divide both sides by 3.

To solve the equation 3x = 44, the first step is to isolate the variable x on one side of the equation.

To achieve this, you need to undo the multiplication by 3 on the left side of the equation.

Since 3x means 3 multiplied by x, you need to divide both sides of the equation by 3.

By dividing both sides of the equation by 3, you are essentially canceling out the effect of the multiplication by 3 on the left side.

This step allows you to isolate the variable x.

So, the correct first step to solve the equation 3x = 44 is to divide both sides by 3.

Hence the correct option is 4th.

Answer:

The correct options is (a)

The simplified form of the given expression (2ab/a⁻⁵b²)⁻³ is b³/8a¹⁸. The correct answer is option A.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given as follows:

(2ab/a⁻⁵b²)⁻³

= [(2ab) / (a⁻⁵b²)]⁻³

Use the negative exponent rule: a⁻ⁿ = 1/aⁿ and simplify the denominator

= [(2a.a⁵b) / (b²)]⁻³

Combine the coefficients 1 and 5 to get

= [(2a⁶) / (b)]⁻³

= 1/[(2a⁶) / b]³

= 1/[(2a⁶)³ / b³]

Cube the resulting expression to get

= b³/8a¹⁸

Therefore, b³/8a¹⁸ is the simplified form of (2ab/a⁻⁵b²)⁻³.

Hence, the correct answer is option A.

Answer:

546 ft³

Step-by-step explanation:

In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.

Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²

Area of the rectangle: 1.5*11 = 16.5 ft²

Total area: 120 + 16.5 = 136.5 ft²

Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³

Answer:

-64

Step-by-step explanation:

geometric

equation

a1(r)^n-1

-1/2(2)^8

Given sequence is -1/2, -1, -2, -4,...

We get,

a1 = -1/2

r = 2

n = 8

So,

a8 = a.r^(n-1)

a8 = -1/2 * 2^(8-1)

a8 = -1/2 * 2^7

a8 = -1/2 * 128

a8 = -64

Therefore, 8th term of the sequence is -64

A common ratio multiplied to each term to get the next term is a non-zero number is a geometric sequence. An example of a Geometric sequence is 2, 4, 8, 16, 32, 64, … , where the common ratio is 2.
