ANSWER

[tex] \sqrt{13} = 3.606[/tex]

to the nearest thousandth.

EXPLANATION

The given irrational number is

[tex] \sqrt{13} [/tex]

We use the calculator to evaluate this to obtain,

[tex] \sqrt{13} = 3.605551...[/tex]

To round to the nearest thousandth means we are rounding to 3 decimal places.

The third decimal place is 5.

The next number is 5 so we round up.

[tex] \sqrt{13} = 3.606[/tex]

Answer:

[tex]y\geq 3x-1[/tex] ; [tex]x+3y\leq 6[/tex]

Step-by-step explanation:

we know that

step 1

Find the inequality of the solid line x+3y=6

The solution is the shaded area below the solid line

therefore

The equation of the inequality is

[tex]x+3y\leq 6[/tex]

step 2

Find the inequality of the solid line y=3x-1

The solution is the shaded area above the solid line

therefore

The equation of the inequality is

[tex]y\geq 3x-1[/tex]

therefore

The system of linear inequalities is

[tex]y\geq 3x-1[/tex] ; [tex]x+3y\leq 6[/tex]

The correct system of linear inequalities represented by the graph is 'y ≥ 3x – 1; x + 3y ≤ 6'. This means all points that lie on and above the line y = 3x - 1 and also on or below the line x + 3y = 6 are solutions.

Looking at the given options and their corresponding inequalities, it’s evident that the graph must represent an area where y is greater or equal to 3x-1, and also, x + 3y is less than or equal to 6.

Therefore, the correct system of linear inequalities whose solution represents the graph should be:

y ≥ 3x – 1; x + 3y ≤ 6

This suggests that all points that lie on the line y = 3x - 1 and above it and all points that are on the line x + 3y = 6 and below it, make both inequalities true at the same time.

Answer:

(D) [tex]8.46\cdot 3.51^x[/tex]

Step-by-step explanation:

One could run this on a computer and verify the best fit through brute force. The more elegant way is, as usual, to think: What are special values of x for an exponential function? Zero, for starters - anything to the power of zero is 1. The function value for x=0 in the table is 10. Which choices A through D are close to 10 for x=0? Well, (C) and (D), the rest is too far. Next, what is the function value for the next easy one, x=1? The table says 30. Which of (C) and (D) is close to 30 for x = 1. It turns out we can safely exclude (C) because 10.84*1.77 is about 19 and that's way too far from 30. Let's check (D): 8.46*3.51=29.7 - that's quite close. Since there is no other candidate left, I bet my money on (D). Feel free to verify closeness for the other values of x if you are unconvinced yet.  

Answer:

[tex]\text{D. }y = 8.46(3.51)^{x}[/tex]

Step-by-step explanation:

The quickest way is probably to do some direct substitution.

First, let's try f(0).

The values of y predicted by the four equations are, respectively, 3.14, 5.32. 10.84, and 8.46.

It looks like C and D are the closest to the observed data.

Now, let's try f(4) on C and D.

C: 10.84(1.77)⁴ = 10.84 × 9.815 = 106.4

D:  8.46(3.51)⁴ =    8.46 × 151.4 = 1284

The best curve is [tex]y = 8.46(3.51)^{x}.[/tex]

Answer:

at t=4, the particle is at x = 20

Step-by-step explanation:

This question revolves around velocity and displacement of a particle moving in a straight line (along the x-axis). At t = 0 the particle is at x = 0. The velocity of the particle as function of time is given as;

v(t) = 5

The velocity is thus constant, implying further that the particle has 0 acceleration.

To find the position of the particle at t = 4, we employ integral calculus since displacement is an integral of velocity while velocity is a derivative of displacement.

In short, we shall be integrating the velocity function between t =0 and t = 4 to find its location at t = 4.

[tex]\int\limits^4_0 {5} \, dt[/tex]

The integral of 5 with respect to t is 5t + c but we ignore the constant of integration since we are dealing with a definite integral;

5t

The final step is to substitute t with the limits given;

5(4) - 5(0) = 20

The particle was moving along the x-axis, so its new position would be;

x = 20

A particle moving with constant velocity v(t) = 5m/s on the x-axis starts from x = 0. At t = 4 seconds, using the equation of motion (x = xo + vt), we calculate the particle's position to be x = 20m.

The physics question asked here pertains to motion along a line, known as 1-Dimensional Kinematics. Specifically, we are considering a particle moving with a constant velocity, given by v(t) =5 for any time t greater than, or less than 0.

To find the position of the particle at a given time, we can use one of the basic equations of motion:

x = xo + vt.

As per the problem, the particle starts from position x = 0 at time t = 0, so xo = 0. The velocity, v, is a constant 5m/s.  We can use the provided time, t = 4 seconds, and substitute these values in the equation to get:

x = 0 + 5*4.

Therefore, at t = 4 seconds, the particle is at position x = 20m along the x-axis.

Final answer:

To use order numbers in different forms, you convert between fractions, decimals, and percents. For example, to convert from percent to decimal, you divide by 100; to convert from decimal to percent, you multiply by 100.

Explanation:

You can use order numbers that are written as fractions, decimals, and percents for various mathematical and real-life applications. They are different ways to represent the same value, and you can convert between them. For example, to convert a percent to a decimal, you write the value of the percent as a fraction with a denominator of 100 and divide the numerator by the denominator. Similarly, to convert a decimal to a percent, you write the decimal as a fraction. If the denominator of the fraction is not 100, convert it to a fraction with a denominator of 100, then write the fraction as a percent.

Example of Converting Percents

To convert 75% to a decimal, write it as 75/100, which simplifies to 0.75. Conversely, to convert 0.75 to a percent, you multiply by 100 to get 75%.

Answer:

240 degrees.

Step-by-step explanation:

The minute hand passes through  60 minutes ( = 360 degrees) in 1 hour.

In 2/3 hours it passes through 2/3 * 360 =  240 degrees.

The number of degrees moved by the minute hand of a clock in a given amount of time is 240 degrees.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that the minute hand of a clock in the given amount of time of 2/3 hour.

The minute hand passes through 60 minutes Or 360 degrees in 1 hour.

In 2/3 hours, it passes through;

2/3 x 360 =  240 degrees.

Therefore, the number of degrees moved by the minute hand of a clock in a given amount of time is 240 degrees.

Answer: D) All of these are correct

Answer:

D. All of these are correct

Step-by-step explanation:

She needs four inches of ribbon and each spool has 24 inches, so we can write this equation like:

384/24 = s

where s is the number of spools.

If we divide 384 inches by the 24 inches each spool has she will get how many spools she needs.

Now having the equation: 384/24 = s, we can change it and it will mean the same.

384/24 = s  is the same as 24s = 384; just sending the 24 to multiply on the other side.

And it is the same as 384/s = 24 just sending the s to the other side dividing.

So all of the answers are correct they are just in different orders.

Answer:

B option. AB is larger than FD

Step-by-step explanation:

The rule which must be remembered here is:

The side opposite to the larger angle will be larger in measure. We have to compare two sides that are opposite to two angles 72 and 65.

So using the above rule we can say that side opposite to angle 72 will be greater in measure than the side opposite to 65.

The side opposite to 72 is AB and side opposite to 65 is FD.

Therefore, we can conclude that AB is larger in measure than FD, which makes option B as the correct answer,

Answer:

The correct answer option is AB is longer than FD.

Step-by-step explanation:

We are given two triangles, ΔABC and ΔDEF, where AC ≅ FE and BC ≅ DE.

One out of three angles is known for each triangle: ∠ACB = 72° and ∠DEF = 65° and we are to determine which of the statements is correct about AB and FD.

We know that the side opposite to the bigger angle is longer. Since ∠C = 72° is greater than ∠E, therefore side AB is longer than FD.

The radius of the bell's edge is 3 yards.

To find the radius of the bell, we can use the formula for the circumference of a circle: C = 2πr, where r is the radius. Given that the circumference is 18.84 yards, we can solve for r. Rearranging the formula, we have r = C / 2π. Plugging in the values, we get r = 18.84 / (2 * 3.14) = 3 yards.

x = 60°

Answer: The correct answer is 3.

Step-by-step explanation:

You need to write an equation to solve this problem, using x as the number of personal training sessions.

The equation to solve this problem is

35 + 25 x = 65 + 15x

First, subtract 35 from both sides:

25x = 30 + 15x

Subtract 15x from both sides:

10x = 30

The last step is to divide both sides by 10:

x = 3

You can then double check your work to make sure that the answer is correct:

35 + (25 x 3) = 110

65 + (15 x 3) = 110

The y-coordinate of the y-intercept is  [tex]b=-5[/tex]

Step-by-step explanation:

Part a) Which line represents the linear equation [tex]-3y=15-4x[/tex]?

To graph the linear equation find the intercepts

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

[tex]-3y=15-4(0)[/tex]

[tex]-3y=15[/tex]

[tex]y=-5[/tex]

The y-intercept is the point [tex](0,-5)[/tex]

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

[tex]-3(0)=15-4x[/tex]

[tex]4x=15[/tex]

[tex]x=15/4=3.75[/tex]

The x-intercept is the point [tex](3.75,0)[/tex]

Plot the intercepts to graph the linear equation

see the attached figure

Part b) Rewritten in slope-intercept form

we know that

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

where

m is the slope

b is the y-coordinate of the y-intercept

we have

[tex]-3y=15-4x[/tex]

convert to slope intercept form

isolate the variable y

[tex]3y=4x-15[/tex]

[tex]y=(4/3)x-5[/tex]

The slope is  [tex]m=(4/3)[/tex]

The y-coordinate of the y-intercept is  [tex]b=-5[/tex]

The function that models the total earnings will be E = 2.50n + 24.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given,

Sam earns $2.50 per person as a tip.

For n number of people the earnings through tip = $2.50n

The earning per hour = $6

For 4 hours the earning = $6 x 4 = $24

Total earning E = 2.50n + 24
