What’s 2(b+3y+4z+7) if b=3 and y=6 and z=1

Answer:

The equation that would give the number of parts produced per hour, [tex]P_H[/tex] is given as follows;

[tex]P_H[/tex] = P/H - 100/H

Step-by-step explanation:

The given parameters are;

The number of parts produced is given by the equation, P = 14·x + 100, where x represents the number of hours worked on a particular day

The number of hours worked = H

Therefore, we have;

P = 14·H + 100

At H = 0, P₀ = 100

At H = 1, P = 114

At H = 2, P = 128

Therefore, the rate of change of the number of parts produced with the number of hours spent = The number of parts produced per hour, ΔP/ΔH = [tex]P_H[/tex], is given as follows;

ΔP/ΔH = [tex]P_H[/tex] = (P - P₀)/(H - 0) = P/H - P₀/H = (128 - 100)/(2 - 0) = 14

∴ The number of parts produced per hour, [tex]P_H[/tex] = P/H - 100/H.

Answer:

The radius increase when the volleyball is fully inflated is 0.5

Step-by-step explanation:

Volume of Partially inflated volleyball = 180 in³

Volume of Full inflated volleyball = 294 in³

We need to find how much does the radius increase when the volleyball is fully inflated?

First we will find the radius of both Partially inflated and Full inflated volleyball. Then we will find increase in radius.

The formula for Volume of sphere is: [tex]Volume=\frac{4}{3}\pi r^3[/tex]

Finding Radius of Partially inflated volleyball

Volume = 180

Putting values and finding radius of Partially inflated volleyball

[tex]Volume=\frac{4}{3}\pi r^3\\180=\frac{4}{3}*3.14*r^3\\4.186r^3=180\\r^3=\frac{180}{4.186}\\r^3=43.0\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{47}\\r= 3.6[/tex]

So, radius of Partially inflated volleyball is r = 3.6

Finding Radius of Fully inflated volleyball

Volume = 294

Putting values and finding radius of Fully inflated volleyball

[tex]Volume=\frac{4}{3}\pi r^3\\294=\frac{4}{3}*3.14*r^3\\4.186\:r^3=294\\r^3=\frac{294}{4.186}\\r^3=70.23\\Taking\:cube\:root\:on\:both\:sides\\\sqrt[3]{r^3}=\sqrt[3]{70.23}\\r= 4.1[/tex]

So, radius of Partially inflated volleyball is r = 4.1

Now, finding increase in radius by subtracting radius of fully inflated volleyball with partially inflated volleyball

Increase in radius of Fully inflated volleyball = 4.1 - 3.6

Increase in radius of Fully inflated volleyball = 0.5

So, the radius increase when the volleyball is fully inflated is 0.5

Answer:

Y=2x+4

Step-by-step explanation:

trust me

Answer: 2x+y+11=0

Step-by-step explanation:

The equation of given line is x-2y-2=0

Slope of given line is (m1)= - coefficient of x÷coefficient of y

m1= -1÷-2 =1÷2

Let slope of required line be m2.

Since the two lines are perpendicular,

So,

m1×m2= -1

or, 1÷2×m2 = -1

m2 = -2

The required line is passing through (4,-3)

Using two points slope form,

y-y1 = m(x-x1)

or, y-(-3)= -2(x+4)

or, y+3= -2x -8

or, 2x+y+3+8 = 0

2x+y+11 = 0 which is required equation of line.

Answer:

Jada will be .6 miles ahead of Elena

Step-by-step explanation:

3 miles per hour times 3 (for the 3 hours) gives you nine miles.

2.8 miles per hour time 3 ( for the 3 hours) give you 8.4 miles.

Subtract 9 by 8.4 to get .6 miles.

Answer:

B:  x  <  -5

A: For the Dentist, their average income in 30 years is $4,282,200

B: For the Manager, their average income in 30 years is $2,592,000

C: The difference in both their earnings is $1,690,200

Work: So, I just multiplied their average earnings by 30, and that's what their average income will be in 30 years. For the difference, I subtracted the higher earning by the lower earning, and that's the difference.

I hope this helps you. :)

Answer:

x = 20

Step-by-step explanation:

The 2 given angles are alternate interior angles and are congruent, thus

7x - 3 = 6x + 17 ( subtract 6x from both sides )

x - 3 = 17 ( add 3 to both sides )

x = 20

Answer:140mm

Step-by-step explanation:because if it’s below 5 round down

The error interval for the length of the stick is [141.5,142.5) and this can be determined by using the rules of approximation.

Given :

The length of a stick is 142mm correct to the nearest millimeter.

The following steps can be in order to determine the error interval for the length of the stick:

Step 1 - The rules of approximation can be used in order to determine the error interval for the length of the stick.

Step 2 - If the value is 141.5 or lesser than the value of 142.5 then the value approximate value becomes 142.

Step 3 - So, the error interval for the length of the stick is [141.5,142.5).

Answer:

[tex]\displaystyle \left(\frac{1}{2},-\frac{5}{2}\right)[/tex]

Step-by-step explanation:

Given a segment defined by the points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

The segment CD is defined by the points in graph C(-3,-4) and D(4,-1). The midpoint is:

Answer:

b = 40

Step-by-step explanation:

A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair.

This situation can be described by an equation of the form y=mx+b , where

x = the time in hours

y = the cost in dollars.

What is the value of b in this equation?

A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair

Writing the above in an equation =

y = $70 × x + $40

y = 70x + 40

Therefore, the value of b in the expression = 40

Answer:

The measure of <TRU is 72 deg.

Step-by-step explanation:

<QRU is a right angle, so it measures 90 deg.

Since m<QRT = 18 deg, then m<TRU must be 72 deg since 72 + 18 = 90.

Answer: The measure of <TRU is 72 deg.

Answer:

The better deal is 8 for $7.50

4 of pack one=$25

2 of pack two=$15

Spent altogether= $40

Answer:

Which is the better deal? Pack of 8 is a better deal.

Buy 4 of Pack One: $24.40

Buy 2 of Pack Two: $11.90

How much did you spend altogether? $36.30

Step-by-step explanation:

Let's start with the Swag Bags. To figure out if something is a good price, divide the items inside of it by the price so you can get the $ per item and compare.

[tex]\frac{6.25}{6}[/tex] = $1.04 per item for Pack of 6

[tex]\frac{7.50}{8}[/tex] = $.94 per item for Pack of 8

Generally, saying "which item is the better deal" refers to which price per item is cheaper. In this case, Pack of 8 is a better deal.

Now, goodie bags.

Pack one costs $6.10 while Pack two costs $5.95.

"Buy 4 of Pack One: $" is asking for the price of 4 Pack Ones. To do this, you simply multiply the pack one price by 4, since you are buying 4 of them.

4 * 6.10 = $24.40

Same idea for Pack Two, just different price and different amount.

2 * 5.95 = $11.90

How much did you spend altogether? Add the total values for both goodie bag packs.

$24.40 + $11.90 = $36.30

Answer:

Student 2 only

Step-by-step explanation:

Given that:

The written antiderivatives formulas by the students for k sin (kx), where  k > 1 are:

Student 1 : [tex]\int (k \ sin (kx)) \ dx= k^2 \ cos (kx) + C[/tex]

Student 2: [tex]\int (k \ sin (kx) ) \ dx = - cos (kx) + C[/tex]

The student that wrote the correct anti-derivate formula is Student 2 only.

This is because:

Suppose:

[tex]I = \int (k \sin (kx) ) \ dx[/tex] where; k > 1

This implies that:

[tex]I = \int (k \sin (kx) ) \ dx[/tex]

[tex]I =k \bigg ( \dfrac{-cos (kx)}{k} \bigg) + C[/tex]   because [tex]\int sin (ax) \ dx = \dfrac{-cos (ax)}{a}+C[/tex]

here;

C = constant of the integration

∴

I = - cos (kx) + C  which aligns with the answer given by student 2 only.
