The sum of four multiples of 4 is 72. Find these numbers.

Answer:

3 meters per second.

Step-by-step explanation:

The formula for finding speed is: [tex]s = \frac{d}{t}[/tex]. D is distance. T is time. So in your case, you would divide 6.0 (distance) by 2.0 (time). Your answer is 3. Add meters per second because you divided meters/seconds.

Answer:

C. [tex]z = -20\sqrt{3}-i\,20[/tex]

Step-by-step explanation:

The rectangular form of a complex number is represented by the following formula:

[tex]z = a+i\,b[/tex] (1)

Where each coefficient can be determined as function of the polar components:

[tex]a = r\cdot \cos \theta[/tex] (2)

[tex]b = r\cdot \sin \theta[/tex] (3)

Where:

[tex]r[/tex] - Magnitude of the complex number, dimensionless.

[tex]\theta[/tex] - Direction of the complex number, measured in radians.

If we know that [tex]r = 40[/tex] and [tex]\theta = \frac{7\pi}{6}[/tex], then the rectangular form of the number is:

[tex]a = 40\cdot \cos \frac{7\pi}{6}[/tex]

[tex]a = -20\sqrt{3}[/tex]

[tex]b = 40\cdot \sin \frac{7\pi}{6}[/tex]

[tex]b = -20[/tex]

The rectangular form of [tex]z=40\cdot\left(\cos \frac{7\pi}{6}+i\,\sin \frac{7\pi}{6}\right)[/tex] is [tex]z = -20\sqrt{3}-i\,20[/tex]. The correct answer is C.

24/7

Step-by-step explanation:

Answer:

The first one, 24/7

Step-by-step explanation:

The first thing that you would want to do is find the most common denominator which would be 21. then the fractions would be 72/21 and 70/21. In this case, 24/7 is bigger.

Answer:

[tex]89\ \text{minutes}[/tex]

Step-by-step explanation:

Let the number of minutes Ravi spoke for be [tex]x[/tex]

The fixed monthly fee is $2

Per minute Ravi is charged 12¢ = $0.12

The charge in a month will be

[tex]y=2+0.12x[/tex]

In one month Ravi was billed $12.68. So [tex]y=12.68[/tex]

[tex]12.68=2+0.12x\\\Rightarrow x=\dfrac{12.68-2}{0.12}\\\Rightarrow x=89\ \text{minutes}[/tex]

So, Ravi spoke for [tex]89\ \text{minutes}[/tex] that month.

Answer:

B

Step-by-step explanation:

Plug the coordinates in the answer choices to see if they give you 18.

Option A:  5(5) - 2(3) = 25- 6 = 9. Not it

Option B: 5(4) - 2(1) = 20 - 2 = 18. Works.

It has to be B because we've already tested (5,3) in option A and it wasn't correct.

Answer:

2.03 cupcakes per minute.

Step-by-step explanation:

The baker can decorate (61/30) cupcakes per minute, hence she can decorate 2.03 cupcakes per minute.

Hope this helped!

Answer:

The baker can decorate 2 cupcakes per minute

Step-by-step explanation:

The baker can decorate 2 cupcakes per minute and to find this you would divide 61 by 30 and you'd get 2.03333 repeating but you can't decorate three hundredths of a cupcake so you would round it to the nearest whole number to get 2 cupcakes per minute

Answer:

Micah age = x - 6

Micah age is 8 when Raul is 14

Step-by-step explanation:

Let

Raul age = x

Micah is 6 years younger than Raul.

Micah age = x - 6

Find Micah age when Raul is 14.

Micah age = Raul age(x) - 6

= 14 - 6

= 8

Micah age = 8 years

Micah age is 8 when Raul is 14.

Answer:

x = 9

Step-by-step explanation:

The standard form of equation of a line is expressed as y = mx+c

m is the slope

c is the y intercept

Note that the line does not have a slope and the x intercept of the line is a point where the line cuts the x axis. Hence the equation of the line will be expressed as x = c where c is the x intercept;

From the graph, the x intercept =9. Hence the equation of the given line is x = 9

Answer:

(b) Along the straight line from (0, 0, 0) to (0, 1, 1), x = 0, y = 0, dx = 0, dy = 0, while z ... 6(1)(1)}dx + {2(1)+3x(1)} + {1 – 4x(1)(19°30 = S (3x' – 6)dx=-5 ... (c) The straight line joining (0,0,0) and (1, 1, 1) is given in parametric form by x = 1, y = 1, z = 1. ... From this it follows that the line integral around any closed path in R is zero, ...

Step-by-step explanation:

The functions that are symmetric about the y-axis are;

1) The function in the first option; f(θ) = cos(θ)

2) The function in the third option; f(x) = x²

Reason for the above selection;

Definition;

A function is symmetric about the y-axis is also known to be an even function such that the same value of the function is arrived at when x is replaced with -x

Analysis of the graphs;

First Function Graph; The graph represents the graph of cos (θ)

∴ The function is f(θ) = cos(θ)

The value of the function when x = π, f(π) = -1

Similarly, the value of the when x = -π, f(-π) = -1

f(π) = f(-π)

∴ f(x) = f(-x)

Therefore; the first function is an even function

Second Function Graph; The function of the graph is x = y²

∴ y = √(x)

The value of the function when x = 4, y = f(4) = 2

However, the when x = -4, f(-4) does not exist

f(4) ≠ f(-4)

∴ f(x) ≠ f(-x)

Therefore; the second function is not an even function (the function, x = y², is however symmetric about the x-axis)

Third Function Graph; The function the graph represents is y = x²

The value of the function when x = 2, f(2) = 4

Similarly, the value of the when x = -2, f(-2) = 4

f(2) = f(-2)

∴ f(x) = f(-x)

Therefore; the third function is an even function

From the above, the functions which are symmetric about the y-axis, (even functions) are;

The first and the third functions
