Answer:

Step-by-step explanation:

Generally equation of a line is given as

y=mx+c

Then given the point (x, y)=(0,2)

Therefore x=0 and y=2

y=mx+c

2=m×0+c

2=0+c

Then, c=2

Then intercept is 2

Also given the point (x, y)=(3,4)

x=3 and y=4 and c=2

y=mx+c

4=m×3+2

4=3m+2

4-2=3m

2=3m

Then, m=2/3

Then, the slope of the graph is 2/3

y=mx+c

Now, m=2/3 and c=2

The general equation of the line becomes

y=2/3x+2

Multiply through by 3

3y=2x+6

Then this is the equation of the line

Answer:

6m is the answer

Step-by-step explanation:  We have rounded numbers down and the correct answer is 6.25 =60%  in the illustration it measures 70% =6m rounded up from 5.6

If we refer to reduction r to find meters and input m in the equation to find percent at 6m shown. We can re-arrange at point 6(6m)100 = 36   (6m)100=36/6 =6m 1/100 = 0.6.   or 0.6/6 =1 To find ?r we can show 0.6  as 6r = 0.6 x 100  6r=10   6/10= 4r reduction etc..   60%  to work this out. Based on isolated data of only 6ft being shown and compare the relation with that 0-30%. and 0-40% in change of data with 6= 30% decrease = r  = 6.25 as 6ft is r4 within reduction to 1dp. =3.2 which could be 3.2x 100=+30 etc rearrange and 3.2 x100 =32 +30 is 6.2 

The requried depth at which the intensity will be 60% is 9 meters.

The function which is in format f(x) =aˣ where a is constant and x is variable,  the domain of this exponential function lies   (-∞, ∞).

Here,
Let the y be the intensity at distance x below the surface,
Now, exponential function representing the scenario is given as,
y = abˣ

Where,
a = 100%,
b = constant of variability.

Now,
for x = 0, y = 100%,
a = 100% - - - - (1)

And x = 6, y = 70%,
70 = ab⁶ - - - (2)

Dividing equation 1 by 2,
Gives b = 0.9423

Now,
y = 100(0.9423)ˣ

Put y = 60
60 =  100(0.9423)ˣ
x = 8.69
x≈ 9 meters

Thus, the requried depth at which the intensity will be 60% is 9 meters.

After accounting for exemptions, Melissa's tax is calculated by multiplying her taxable income by the state income tax rate. Due to missing information regarding the value of exemptions, we've assumed Melissa's entire gross pay is taxable. Therefore, she pays $1,560 per year in state income tax.

Based on the information presented in your question, we're to determine state income tax withholdings for an individual named Melissa Sartini. First, we need to subtract any allowable exemptions from Melissa's annual gross pay. In this question, the figures for the married exemptions are not provided so we'll have to assume that Melissa's taxable income is still $52,000.

To calculate the tax, we simply multiply her taxable income by the state income tax rate. The state income tax rate is given as 3%, so we convert 3% to a decimal (0.03) and multiply by $52,000. This gives us:

$52,000 * 0.03 = $1,560

Therefore Melissa has $1,560 withheld each year for state income tax.

The probability that both are country music is 2/87.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that,

Number of CDs = 30

Number of country music CDs = 5

Now , at first when 1st CD is selected

Probability (1st), P(1st) = 5/30 = 1/6

After selecting 1st CD,

Total CDs left will be 29

Number of country music CD= 4

So, for 2nd CD selection,

Probability (2nd), P(2nd) = 4/291

Hence the required probability,

P(1st∩2nd) = P(1st) x P(2nd)

                  = 1/6 x 4/29

                  = 2/87

Hence,the probability that both are country music is 2/87.

Answer:

y = 8

Step-by-step explanation:

remove the constant, 6:

3y=24

divide both by 3. leave x by itself

3y/3=24/3

y = 8

do these steps and you can do these easily

The solution to the equation 3y + 6 = 30 is y = 8.

To solve the equation 3y + 6 = 30 and find the value of y, we need to isolate the variable y on one side of the equation by performing various operations. Here are the steps to solve the equation:

Step 1: Begin with the given equation:

3y + 6 = 30

Step 2: Subtract 6 from both sides of the equation to move the constant term to the other side:

3y + 6 - 6 = 30 - 6

3y = 24

Step 3: Divide both sides of the equation by 3 to isolate the variable y:

(3y)/3 = 24/3

y = 8

Step 4: Verify the solution by substituting the value of y back into the original equation:

3(8) + 6 = 30

24 + 6 = 30

30 = 30

Since the equation is true, we can conclude that the solution to the equation 3y + 6 = 30 is y = 8. By performing the necessary operations, we successfully isolated the variable y and found its value that satisfies the original equation.

Answer: 8x³ - 7x² - 6x + 5

Step-by-step explanation:

8x³ - 7x² - 6x + 5 is a cubic expression.

The variable is x

The variable x has highest power as 3.

8x³ - 7x² - 6x + 5 is a polynomial.

-7x + 4 is a linear expression because highest power of the variable x is 1.

7x² - 5x + 6 is a quadratic expression because the highest power of the variable x is 2.

9x^4 + 8x^3 - 6x^2 - 2x + 11 is a polynomial with the highest power of the variable being 4.

The expression that represents a cubic expression is 8x³ − 7x² − 6x + 5, as it contains the highest power of x raised to 3, making it a cubic polynomial.

A cubic expression is a type of polynomial with the highest degree term being raised to the power of 3. In mathematical terms, it is represented as f(x) = ax^3 + bx^2 + cx + d, where 'a' is the coefficient of the cubic term, 'b' is the coefficient of the quadratic term, 'c' is the coefficient of the linear term, and 'd' is the constant term.

Among the options provided:

- −7x + 14 is a linear expression as it contains only a single degree term (degree 1).

- 7x² − 5x + 6 is a quadratic expression as it contains a term with x^2 (degree 2).

- 8x³ − 7x² − 6x + 5 is indeed a cubic expression as it contains a term with x^3 (degree 3).

- 9x⁴ + 8x³ − 6x² − 2x + 11 is a quartic expression with the highest power of x being 4 (degree 4).

Therefore, the expression that represents a cubic expression is 8x³ − 7x² − 6x + 5, as it has the highest power of x equal to 3.

Final answer:

The expression simplifies to [tex]1/t^72[/tex] by using exponent rules to multiply the exponents and then applying the rule for negative exponents.

Explanation:

To simplify the expression [tex](t^9)^-8[/tex] , you need to use the exponent rules.

Specifically, when you have a power raised to another power, you multiply the exponents.

Here, you have the base t raised to the 9th power, and then that result is raised to the -8th power.

The rule is: [tex](a^m)^n = a^(m*n).[/tex]

Applying this rule here gives us:

[tex]= (t^9)^-8[/tex]

[tex]= t^(9*-8)[/tex]

[tex]= t^-72.[/tex]

Since we are dealing with a negative exponent, the rule for negative exponents says that [tex]a^-n = 1/a^n.[/tex]

Therefore, our final simplified expression is [tex]1/t^72.[/tex]

The perimeter of the given shape is 63.50 units and its area is 170.625 square units.

Step-by-step explanation:

Step 1:

First, we need to determine the distance between each of the points in the shape ABCDEFGH.

There are vertical lines and horizontal lines. The distances between vertical lines are found by calculating the difference in y values while for horizontal lines, the distances are found by calculating the difference between the x values.

Step 2:

Distance of line AB, 15 - 4.5 = 10.5,

Distance of line BC, 14 - 8 = 6,

Distance of line CD, 15 - 10 = 5,

Distance of line DE, 8 - 3 = 5,

Distance of line EF, 15 - 10 = 5,

Distance of line FG, 3 - (-2.25) = 5.25,

Distance of line GH, 15 - 4.5 = 10.5 and

Distance of line AH, 14 - (-2.25) = 16.25.

Step 3;

The area of ABCDEFGH = The area of ABGH - the area of CDEF.

The area of ABGH = Length × Width = AH × AB = 16.25 × 10.5 = 170.625 square units.

The area of CDEF = Length × Width = CD × DE = 5 × 5 = 25 square units.

The area of ABCDEFGH = 170.625 - 25 = 145.625 square units.

Step 4:

The perimeter of shape ABCDEFGH is just the sum of all its lines.

Perimeter of ABCDEFGH = 10.5 + 6 + 5 + 5 + 5 + 5.25 + 10.5 + 16.25 = 63.50 units.

Answer:

the second option 2/5 and (3, -2)

Step-by-step explanation:

first for the slope you do rise over run. Meaning you find a point on the graph intersects "cleanly" as in (-2,-4) then find another point on the graph where the line intersects (3,-2). to find the slope you do the change in Y over the Change in X so what that means is that tou would take one Y value and subtract it from the otherY value (from the two points you just found) so in this example (-4)-(-2) which equals -2. then you do the same process for the X values (make sure to start with the same point) so (-2)-(3) which equals -5. then you divide (or leave as a fraction in this case) -2/-5 which simplifies to 2/5. so The slope is 2/5.

Answer:u=1/16

Step-by-step explanation:

u is inversely proportional to v^2

u=k× 1/v^2

u=k/v^2

When U=4/9 when v=3

4/9=k×1/3^2

4/9=k×1/9

4/9=k/9

Cross multiply

4×9=k×9

36=9k

Divide both sides by 9

36/9=9k/9

4=k

When v= 8, u=?

u=k/v^2

Recall k=4

u=4/8^2

u=4/64

u=1/16
