How to define a linear function?

The slope-intercept representation of a linear function is given by the equation presented as follows:

y = mx + b

The coefficients of the function and their meaning are described as follows:

m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.

The intercept of the line in this problem is given as follows:

b = 26.

Hence $26 is the monthly cell phone bill when shared data equals zero.

What are the answers to these questions?

Answers

Step-by-step explanation:

the inside expression of an absolute value expression can be positive or negative, but the result is only the positive one.

therefore, for our example here the negative case would be

2.5x - 6.8 = -12.9

which gives us

2.5x = -6.1

x = -6.1/2.5 = -2.44

and the positive case would be

2.5x - 6.8 = 12.9

and that gives us

2.5x = 19.7

x = 19.7/2.5 = 7.88

Answers

Answer:

Step-by-step explanation:

So we have ratio of 5 red:10 yellow.

So 10+5=15. 75/15=5

So there are 5*5=25 red flowers and 5*10=50 yellow flowers.

Answer:

Step-by-step explanation:

What you need to do first is divide 75 ÷ 5, which eqals 15. Then divide 15 ÷ 5. which is 3. Now multiply 3 x 10. Which is 30.

Find the angle θ between a = 3i − k, b = 2i + 2k

Answers

We can use the dot product formula to find the angle between the vectors:

a · b = ||a|| ||b|| cos(θ)

where ||a|| and ||b|| are the magnitudes of the vectors a and b, respectively.

First, we need to find the magnitudes of the vectors:

||a|| = sqrt(3^2 + 0^2 + (-1)^2) = sqrt(10)
||b|| = sqrt(2^2 + 0^2 + 2^2) = 2sqrt(2)

Then, we can calculate the dot product:

a · b = (3i - k) · (2i + 2k)
a · b = 6 + 0 - 2
a · b = 4

Now we can solve for the angle θ:

a · b = ||a|| ||b|| cos(θ)
4 = sqrt(10) * 2sqrt(2) cos(θ)
cos(θ) = 4 / (sqrt(10) * 2sqrt(2))
cos(θ) = 2 / sqrt(5)

Finally, we can calculate the angle θ:

θ = cos^-1(2 / sqrt(5))
θ ≈ 54.7 degrees

Therefore, the angle between a and b is approximately 54.7 degrees.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Now, Using the formula for the present value of an annuity, with a rate of 6% and 20 years, we get:

Present Value = $2,000,000 [ (1 - (1+0.06)⁻²⁰) / 0.06 ]

= $2,000,000 [ (1 - 0.312) / 0.06 ]

= $31,333,333.33

So, the present value of the estimated toll revenue for the proposed highway construction is approximately $31,333,333.33.

What is the sum of the first six terms of the geometric series?

Answers

Answer:

S₆ = - 364

Step-by-step explanation:

the sum to n terms of a geometric series is

$S_{n}$ = $\frac{a_{1}(r^{n}-1) }{r-1}$

where a₁ is the first term and r the common ratio

here a₁ = 2 and r = $\frac{a_{2} }{a_{1} }$ = $\frac{-6}{2}$ = - 3 , then

S₆ = $\frac{2((-3)^{6}-1) }{-3-1}$

= $\frac{2(729-1)}{-4}$

= $\frac{2(728)}{-4}$

= $\frac{1456}{-4}$

Volume of sphere =

Density

TT = 3.142
Which ball should he choose?

Answers

Dylan should choose Ball B which having lowest density.

What is volume of spere?

The volume of a sphere is calculated using the formula volume = 4/3πr³ where r is the sphere's radius.

Given that:

Ball A = diameter 7cm, mass 1.742kg

Ball B = diameter 6cm, mass 1.040kg

As we know that,

volume of a sphere =4/3πr³

1) For Ball A,

volume of a Ball A = 4/3π(3.5)³

volume of a Ball A = 179.6 cm³

given mass for Ball A is 1.742 kg = 1742 g.

So, Density = $\frac{mass}{volume}$

Density of Ball A will be 9.7 g/cm³.

2) For Ball B,

volume of a Ball B = 4/3π(3)³

volume of a Ball B = 113.11 cm³

given mass for Ball B is 1.040 kg = 1O40 g.

So, Density = $\frac{mass}{volume}$

Density of Ball B will be 9.19 g/cm³.

By comparing density of both balls,

Density of Ball A > Density of Ball B

Hence, Dylan should choose Ball B which having lowest density.

The sum of the sides of a regular polygon is 96ft, find the measure of it side.

Answers

Answer:

two are supplementary. the measure of one of these angles is 12 degrees less than one-third the measure of the other.what is the measure of each angle

Let's call the measures of the two angles x and y, where x is the larger angle. We know that the two angles are supplementary, which means they add up to 180 degrees:

x + y = 180

We also know that one of the angles (let's say y) is 12 degrees less than one-third the measure of the other angle (x):

y = (1/3)x - 12

Now we can substitute the second equation into the first equation to solve for x:

x + (1/3)x - 12 = 180

Multiplying both sides by 3 to get rid of the fraction, we have:

3x + x - 36 = 540

Combining like terms, we get:

4x - 36 = 540

Adding 36 to both sides, we get:

4x = 576

Dividing both sides by 4, we get:

x = 144

Now we can use the first equation to solve for y:

144 + y = 180

Subtracting 144 from both sides, we get:

y = 36

Therefore, the measures of the two angles are 144 degrees and 36 degrees.

The sum of the sides of a regular polygon is 96ft, find the measure of it side.

Let's say that the regular polygon has n sides, and each side has length s. The formula for the sum of the sides of a regular polygon is:

sum of sides = n * s

We know that the sum of the sides is 96ft, so we can write:

96 = n * s

We want to find the length of each side, so we need to isolate s on one side of the equation. We can do this by dividing both sides by n:

s = 96/n

Now we can substitute this expression for s into the formula for the perimeter of a regular polygon:

Perimeter = n * s

Perimeter = n * (96/n)

Simplifying this expression, we get:

Perimeter = 96

We know that the perimeter of a regular polygon is the sum of the lengths of all its sides, so we can divide the perimeter by the number of sides to find the length of each side:

s = Perimeter / n = 96 / n

Therefore, the length of each side of the regular polygon is 96/n feet. We cannot determine the value of n from the given information in the problem.
