Answer: A line with a slope of 2

Step-by-step explanation: the slope of the line is -1/2 so the negative reciprcal of the slope is 2 (It would be perpendicular to it)

i used m=y2-y2/x2-x1 to figure ou the slope and -(x/y) as the negative reciprcal for the perpendicular line.

Answer:

5.4 ft

Step-by-step explanation:

Given that the volume of the hemisphere sphere, [tex]V= 324 ft^3[/tex].

Let r be the radius of the hemisphere.

As the volume of the hemisphere, [tex]V=\frac {2}{3}\pi r^3[/tex]

By using the given value, we have

[tex]\frac {2}{3}\pi r^3=324[/tex]

[tex]\Rightarrow r^3=\frac{324\times 3}{2\pi} \\\\\Rightarrow r^3=\frac{324\times 3}{2\times3.14} \\\\\Rightarrow r^3=154.78 \\\\\Rightarrow r=\left( 154.78 \right)^{1/3} \\\\[/tex]

[tex]\Rightarrow r=5.4[/tex] ft

Hence, the radius of the hemisphere is 5.4 ft.

The solution to the given inequality is: I only.

An inequality can be defined as a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following arguments:

When x = -10, a solution to the inequality is given by:

-7 ≥ 2 + 5x

-7 ≥ 2 + 5(-10)

-7 ≥ 2 - 50

-7 ≥ -48 (True).

When x = 3, a solution to the inequality is given by:

-7 ≥ 2 + 5x

-7 ≥ 2 + 5(3)

-7 ≥ 2 + 15

-7 ≥ 17 (False).

When x = -1, a solution to the inequality is given by:

-7 ≥ 2 + 5x

-7 ≥ 2 + 5(-1)

-7 ≥ 2 - 5

-7 ≥ -3 (False).

Therefore, the solution to the given inequality is "I only."

Answer:

m∠W = (4x)° = 4 × 18 = 72°

m∠Y = (3x)° = 3 × 18 = 54°

m∠Z = (3x)° = 3 × 18 = 54°

Step-by-step explanation:

m∠W = (4x)°

m∠Y = (3x)°

m∠Z = (3x)°

i.e.,

We Know That,

The sum of a Triangle is 180°

So,

m∠W + m∠Y + m∠Z

i.e.,

(4x)° + (3x)° + (3x)° = 180°

10x° = 180°

x = 180/10

x = 18°

Now,

m∠W = (4x)° = 4 × 18 = 72°

m∠Y = (3x)° = 3 × 18 = 54°

m∠Z = (3x)° = 3 × 18 = 54°

Thus, x = 18°

(4x)° + (3x)° + (3x)° = 180°

4 × 18 + 3 × 18 + 3 × 18 = 180

72° + 54° + 54° = 180°

180° = 180°

Hence, L.H.S = R.H.S

Answer:

A. y=[tex]\frac{3}{2}[/tex]x-3

B.y=[tex]\frac{-3}{4}[/tex]x-3

Step-by-step explanation:

Okay so essentially, the first thing you need to do is find the slope and y intercept for each equation. To find the slope, I like to look at the two points and divide the rise (How much it goes up or down) by the run (How much it moves left or right). For A the rise is 6 and the run is 4, so the slope is 6/4 or 3/2. To find the equation for A, you also need the y-intercept which is just the y value (how high up or down) it is when it crosses the y axis. In graph a, this is at -3. Because the equation of a line is y=mx+b (m being slope and b being y intercept), we know the equation for a is y=[tex]\frac{3}{2}[/tex]x-3. We can do the same thing for B. The rise is -3 and the run is 4, so the slope is -3/4. The y value when x is equal to zero is 2, so that is the y intercept. The equation is y=[tex]\frac{-3}{4}[/tex]x-3

In this equation, it will require 175 + 7x - 550 - 8x water to fill both tanks to the same level.

A formula that describes how two expressions on each side of a sign are connected. It typically has an equal sign and one variable. akin to this 2. 2x - 4 = 2. The variable x is present in the preceding example.

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the expressions 3x + 5 and 14 make up the equation 3x + 5 = 14, with the word "equal" separating them.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

Answer:28

Step-by-step explanation:

f(0) =  ( f(k) +f(-k) ) / 2

f(0) = (16 - 4) / 2

f(0) = 12 / 2

f(0) = 6  → ANSWER

*Remember that f(0) = m(0) + n = n

If we have f(x) = mx + n, then:

f(k)= mk + n     and       f(-k)= -mk + n

If we add them:

  f(k) + f(-k)

= mk + n -mk + n

= 2n

= 2f(0)

So we conclude that:

f(0) = [f(k) + f(-k)] / 2

[tex]a_{n}[/tex] = - 4n + 12

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 8 and d = a₂ - a₁ = 4 - 8 = - 4 , then
