Answer:

D

Step-by-step explanation:

f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15)  Remove the brackets

f(x) - g(x) = -9x^2 - 7x  + 12 - 3x^2 + 4x + 15

f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15

f(x) - g(x) = -12x^2- 3x + 27

Answer D

Answer:

Option D. -12x² - 3x + 27

Step-by-step explanation:

The given functions are f(x) = -9x² - 7x + 12 and g(x) = 3x² - 4x - 15

We have to find the value of f(x) - g(x)

f(x) - g(x) = (-9x² - 7x + 12) - (3x² - 4x - 15)

              = -9x² - 7x + 12 - 3x² + 4x + 15

              = (-9x² - 3x²) - (7x - 4x) + 12 + 15

              = -12x² - 3x + 27

This value of f(x) - g(x) matches with option D.

Therefore, Option D. is the correct option.

Answer:

There are 8 cans on each of the equal shelves

Step-by-step explanation:

Total number of cans put in display = 35

Shelves with equal no of cans =  4 Shelves

And one shelf displays only 3 cans

Therefore, 4 shelves with equal no of cans + 1 shelf with 3 cans = 35 cans

Let us assume equal no. of cans be x

We get, 4x + 3 = 35

             4x = 35 - 3

             4x = 32

              x  = 32 ÷ 4

              x = 8

Thus, 4 shelves with equal no of cans contains 8 cans each.

Answer:

The company should charge $ 3.25 for the smaller size.

Step-by-step explanation:

The price per ounce of the 32-ounce product is required to be 25% greater than the larger-sized product.

We know that for the size of 48 ounces the price is $ 3.90

So, the price per ounce is:

[tex]\frac{3.90}{48}[/tex]= $ 0.08125

For the smallest size the price per ounce should be 25% higher.

So:

$ 0.08125 (1 + 0.25) = $ 0.10156

The total price for the smallest size is:

$ 0.10156 * 32 = $ 3.25

The company should charge $ 3.25 for the smaller size.

Answer:

3.25

Step-by-step explanation:

We could solve this problem by figuring out the per-ounce cost of the 48-ounce package, increasing it by $25\%$, and then multiplying that by 32 for the smaller package. However, if we simply increase the price by $25\%$, and then scale the package size down to 32 ounces from 48 ounces, these are the same calculations, but in a different order that makes it easier to calculate. Thus: $3.90 \times 1.25 \times \frac{32}{48} = \boxed{3.25\text{ dollars}}$

To calculate SUTA and FUTA for the first 12 weeks, calculate the taxable wages for each employee. Multiply the taxable wages by the respective tax rates to find the amount owed. Roger owes $371 for SUTA and $56 for FUTA for the first 12 weeks.

To calculate the amount that Roger owes for SUTA (State Unemployment Tax Act) and FUTA (Federal Unemployment Tax Act) for the first 12 weeks, we need to calculate the taxable wages for each employee. The taxable wages for SUTA is the first $7,000 and for FUTA is the first $7,000 as well.

Since the three employees earn $500, $550, and $700 respectively, their total wages for the first 12 weeks would be $17,100 (12 weeks x ($500 + $550 + $700)). However, since SUTA and FUTA only consider the first $7,000 of wages, we can calculate the amount for each tax.

For SUTA, the total taxable wages would be $7,000. Using the SUTA rate of 5.3%, we can calculate the amount owed: $7,000 x 0.053 = $371.

For FUTA, the total taxable wages would also be $7,000. Using the FUTA rate of 0.8%, we can calculate the amount owed: $7,000 x 0.008 = $56.

Therefore, Roger owes $371 for SUTA and $56 for FUTA for the first 12 weeks for his three employees.

So for this, we will be setting up a system of equations with the information we have:

[tex]x+y=13\ \textsf{"The sum of two numbers is 13."}\\2x-3y=1\ \textsf{"Two times the first number minus three times the second number is 1."}[/tex]

Now we have our system of equations set up. Next, I will be using the substitution method to solve this system. So firstly, subtract y on both sides of the first equation:

[tex]x=13-y\\2x-3y=1[/tex]

Now, substitute x for (13 - y) in the second equation and solve for y as such:

[tex]2(13-y)-3y=1\\26-2y-3y=1\\26-5y=1\\-5y=-25\\y=5[/tex]

Now that we have the value of y, substitute it into either equation to solve for x:

[tex]x+5=13\\x=8\\\\2x-3(5)=1\\2x-15=1\\2x=16\\x=8[/tex]

In short, the first number (x) is 8 and the second number (y) is 5.

The surface area of the cylinder is approximately 191.9 square inches.

The surface area of a cylinder is the sum of the areas of its curved surface and its two circular bases. The formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

where SA is the surface area, r is the radius of the circular base, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14159).

The first term on the right-hand side of the equation (2πr²) represents the area of the two circular bases of the cylinder. The second term (2πrh) represents the area of the curved surface of the cylinder.

The area of the square embedded in the circular base of the cylinder is 18 in², which means each side of the square has a length of √18 in = 3√2 in. Since the square is embedded in the circular base, the diameter of the base of the cylinder is equal to the diagonal of the square, which is 2 times the length of one side, or 6√2 in.

The radius of the circular base is half the diameter, or 3√2 in. The surface area of the cylinder consists of the area of the top circular base, the area of the bottom circular base, and the lateral area (the curved surface area) of the cylinder.

The area of each circular base is πr² = π(3√2)² = 18π in².

The lateral area of the cylinder can be found by multiplying the height (which is given as 10 inches) by the perimeter of the circular base (which is 2πr). The perimeter of the circular base is 2π(3√2) = 6π√2 in. Therefore, the lateral area is 10(6π√2) = 60π√2 in².

The total surface area of the cylinder is the sum of the areas of the two circular bases and the lateral area:

Surface area = 2(18π) + 60π√2

= 36π + 60π√2

≈ 191.9 in² (rounded to one decimal place)

Therefore, the surface area of the cylinder is approximately 191.9 square inches.

Answer:

[tex]\frac{(L x M)}{6}[/tex]

Step-by-step explanation:

The greatest common factor is the greatest number that will divide two values. We have two values L and M. Each has numbers which multiply together to give the number. The highest value or most in common they share is 6. This is the GCF.

The least common multiple is the smallest positive number which is a multiple of the two. This means both L and M divide into it evenly.

We know L x M is a multiple because L and M will be factors of it. But we don't know its the least.

As an example if L= 42 and M = 60, they have GCF 6. We can multiply them to find a multiple 42 x 60 = 2520 but we don't know this is the smallest or least multiple we can find. If we divide by the GCF, 2520/6=420. Interestingly, 42 x 10 =420 and 60 x 7 =420. This means 420 is the least common multiple.

We can multiply (L x M) and then divide by the GCF of L & M to find the least common multiple.

Answer:

The answer is 198.

Step-by-step explanation:

First you need to know how much is a batch of cookies which is 60. Since she made 3 batches that means you will need to multiply 3 by 60, which will give you 180 cookies. Next you will need to add 2 to 10 because thats how much were took. That equals 12. Subtract 12 from 180 and that will give you 168. Last but not least you will need to add 30 because that is half the batch of cookies her neighbor gave to her. So 168 plus 30 equals 198.

Answer:

y-12= -3(x-6) (point slope form)

y = -3x + 30  ( slope intercept form)

Initial delivery time = 30 minutes

delivery time decreases 3 minutes per day

Step-by-step explanation:

To find equation of line we pick two points from the graph

(3,21)  and (6,12)

Point slope form of a line is y-y1= m(x-x1)

m is the slope and (x1,y1) is the point on graph

Lets find out slope m

[tex]m=\frac{y_2-y_1}{x_2-x_1} =\frac{12-21}{6-3} =-3[/tex]

(x1,y1) is (6,12)

Point slope form of a line is y-y1= m(x-x1)

y-12= -3(x-6) (point slope form)

Now we solve for y to get slope intercept form

y-12 = -3x +18

Add 12 on both sides

y = -3x + 30  ( slope intercept form)

(b) To find initial time we plug in 0 for x

y = -3x + 30

y= -3(0) + 30

y=30

Initial delivery time = 30 minutes

Slope is the delivery time decreases per day

We got slope m = -3

So delivery time decreases 3 minutes per day

Answer:

well basically  y-12= -3(x-6) (point slope form)

y = -3x + 30  ( slope intercept form)

Initial delivery time = 30 minutes

delivery time decreases 3 minutes per day

Step-by-step explanation:

To find equation of line we pick two points from the graph

(3,21)  and (6,12)

Point slope form of a line is y-y1= m(x-x1)

m is the slope and (x1,y1) is the point on graph

Lets find out slope m

(x1,y1) is (6,12)

Point slope form of a line is y-y1= m(x-x1)

y-12= -3(x-6) (point slope form)

Now we solve for y to get slope intercept form

y-12 = -3x +18

Add 12 on both sides

y = -3x + 30  ( slope intercept form)

(b) To find initial time we plug in 0 for x

y = -3x + 30

y= -3(0) + 30

y=30

Initial delivery time = 30 minutes

Slope is the delivery time decreases per day

We got slope m = -3

So now we can say that the delivery time decreases 3 minutes per day! Hope this helps :)

To find the length of the wall represented by a line that is 3 7/8 inches long on the blueprint, we can use the scale conversion. The length of the wall is 15 1/2 feet.

To find the length of the wall represented by a line that is 3 7/8 inches long on the blueprint, we need to use the scale conversion.

The given scale is 1 inch corresponds to 4 feet.

So, we can set up a proportion:

1 inch − 4 feet

3 7/8 inches − x feet

To solve for x, we can cross-multiply:

1 × x = 4 × 3 7/8

Multiply 4 by the whole number 3 and then add the product to the result of 4 multiplied by the fractional part 7/8.

x = 12 + 28/8

x = 12 + 3 1/2

x = 15 1/2 feet

Therefore, the length of the wall represented by a line that is 3 7/8 inches long on the blueprint is 15 1/2 feet.

The expression equal to 2x^(2)+8 is:

First option (2x-4i)(x+2i)

Step-by-step explanation:

If we multiply

(2x-4i)(x+2i)=(2x)(x)+(2x)(2i)-(4i)(x)-4i(2i)

Step-by-step explanation:

3.27 Times 10⁻⁴ in standard form is 0.000327. This is found by moving the decimal point in 3.27 four places to the left, resulting in the number 0.000327.

The number 3.27 TImes  10⁻⁴ into standard form.

To do this, we move the decimal point four places to the left, because the exponent on the 10 is negative four.

So, starting with the number 3.27, we move the decimal point to the left four times, which introduces three zeros after the decimal point and before the 327.

The correct answer is B: 0.000327.
