There were two containers of oil. There was twice as much oil in the second container as in the first one. After using 13 liters of oil from the first container and 7 liters from the second one, the second container still had 3 times more oil than the first one. How many liters of oil in total were in both containers originally?

The statement that best compares the graph of g(x) = -5x³ with the graph of f(x) = x³ is that the graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."

Option D is the correct answer.

We have,

Reflection across the x-axis:

The negative coefficient of -5 in g(x) reflects the graph across the x-axis compared to f(x).

This means that the points on the graph of g(x) will have the same

x-coordinates as the corresponding points on the graph of f(x) but will have opposite y-coordinates.

Vertical stretching by a factor of 5:

The absolute value of the coefficient (-5) in g(x) indicates that the graph is vertically stretched by a factor of 5 compared to f(x).

This means that for any given x-value, the corresponding y-value on the graph of g(x) will be five times larger (or smaller, depending on the sign) than the corresponding y-value on the graph of f(x).

Thus,

The graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."

Answer: 5 milimeters.

Step-by-step explanation:

The formula for calculate the volume of a rectangular prism is:

[tex]V=lwh[/tex]

Where "V"  is the volume, "l" is the lenght, "w" is the width and "h" is the height.

You know that the volume, the lenght, and the width of this rectangular prism are:

[tex]V=750mm^3\\l=15mm\\w=10mm[/tex]

Substitutute these values into the formula and solve for the the height "h":

[tex]750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm[/tex]

Final answer:

To find the height of a rectangular prism, you can use the formula V = l x w x h and calculate the missing dimension. In this case, the height of the rectangular prism is 5 millimeters.

Explanation:

A rectangular prism, also known as a rectangular solid or box, is a three-dimensional shape that has six rectangular faces. The formula to find the volume of a rectangular prism is V = l x w x h, where l is the length, w is the width, and h is the height. In this case, the given length is 15 mm, the width is 10 mm, and the volume is 750 cubic mm. To find the height, plug these values into the formula as follows:

750 = 15 x 10 x h

h = 750 / (15 x 10) = 750 / 150 = 5 mm

Therefore, the height of the rectangular prism is 5 millimeters.

3. The input is h

Step-by-step explanation:

The value inside the bracket of the function is the input given to the function.

1. g(f) = 2f

The input is f

2. h(g) = -4+g

The input is g

3. f(h) = h - 7

The input is h

Answer:

g(f)=2f⇒  f

h(g)=-4+g ⇒ g

f (h) =h-7 ⇒h

Step-by-step explanation:

Hi, to answer this question we have to understand what is the input of a function.

A function has an input and an output. The input is inside the parentheses, next to the name of the function.

The input is the independent variable.

Now, with this information, we can match each function with its input.

So:

g(f)=2f⇒  f

h(g)=-4+g ⇒ g

f (h) =h-7  ⇒h

Step-by-step explanation:

f(x) = g(x)

Substitute the functions in

3x+12 = -9.5x -13

Add 9.5x to each side

3x+9.5x+12 = -9.5x+9.5x -13

12.5x +12 = -13

Subtract 12 from each side

12.5x+12-12 = -13-12

12.5x = -25

Divide by 12.5

12.5x/12.5 = -25/12.5

x = -2

Answer:

a. x = −2

f(x) = g(x)

Substitute the functions in

3x+12 = -9.5x -13

Add 9.5x to each side

3x+9.5x+12 = -9.5x+9.5x -13

12.5x +12 = -13

Subtract 12 from each side

12.5x+12-12 = -13-12

12.5x = -25

Divide by 12.5

12.5x/12.5 = -25/12.5

x = -2

Answer:

y = 1/3 x.

Step-by-step explanation:

The slope of the given line is

(4 - (-2) / 2 - 4)

=   -3.

So the slope of the line perpendicular to it = -1 / (-3) = 1/3.

This line also passes through the point (3, 1) so its equation is ( by the point-slope form):

y - 1 = 1/3(x - 3)

y - 1 = 1/3x - 1

y = 1/3 x (answer).

Answer: The answer is y= x/3

Step-by-step explanation:

Given  points =(2,4)  and (4,-2) whose mid point is (3,1)

Let the points be named  as A(2,4) and B(4,-2) and mid point as C(3,1)

So slope of AB = [tex]\frac{4-(-2)}{2-4}[/tex]

=[tex]\frac{6}{-2}[/tex]

= -3

We know that   Product of Slope of perpendicular lines = -1

Now slope of the line perpendicular to AB × slope of AB = -1

-3 × m2 =-1

i.e. m2 =[tex]\frac{1}{3}[/tex]

Now equation of perpendicular bisector of AB passing through C(3,1)  is

[tex]y -1 =\frac{1}{3}(x-3)\\[/tex]

[tex]y= 1+\frac{1}{3}x -1[/tex]

[tex]y=\frac{1}{3}x[/tex]

Hence the equation of line is y =x/3

Check the picture below.

now, based on the provided information, we know the hexagon and triangle are regular polygons, equal sides and equal angles, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.

now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.

if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a full revolution will be 360°, so the remaining angle in green there must be 360° - 120° - 136°  = 104°, and her twin at vertex J is also 104°.

Answer: Jacob ran for half an hour, and walked for the remaining half an hour.  15 km/hr x 0.5 hr = 7.5 km running, and 5km/ hr x 0.5 hr=2.5 km walking

Step-by-step explanation:

Let x hours be the time Jacob ran, and therefore for 1-x hours he walked.

time x speed= distance

we get, 15x + 5*(1-x)=10

15x+5-5x=10,

10x=5,

x=0.5 hours.

Average speed was 10km/h.

HOPE THIS HELPS.

Jacob ran 7.5 km at a speed of 15 km/h. By setting up a system of simultaneous equations, we found the distances for both running and walking that add up to the total distance of 10 km, while also fulfilling the constraint of a 1-hour total journey time.

To solve this problem with simultaneous equations, let's define two variables for the two different parts of the journey: x for the distance Jacob runs at 15 km/h and y for the distance he walks at 5 km/h. We know that Jacob covers a total distance of 10 km and the total time taken for the journey is 1 hour.

Set up the equations:

Equation for the distance: x + y = 10

Equation for the time: (x/15) + (y/5) = 1 (Since time is distance divided by speed)

Solve these equations simultaneously.

Multiply the second equation by 15 to clear the denominators: x + 3y = 15

Subtract the first equation from this new equation to solve for y: 2y = 5, so y = 2.5 km.

Substitute y back into the first equation to find x: x = 10 - 2.5, so x = 7.5 km.

Jacob ran 7.5 km at 15 km/h.

Check the answer:

Is 7.5 km in 1 hour at 15 km/h reasonable? Yes, because 15 km/h means he would run 15 km in 1 hour, so running for less than an hour for 7.5 km is plausible.

A real world situation for the function f(x) = 3(1.06x) + 2 could be a situation where a person is investing money in a savings account. The function represents the balance in the account after a certain amount of time (x years) with an interest rate of 6%.

Explanation:

A real world situation for the function f(x) = 3(1.06x) + 2 could be a situation where a person is investing money in a savings account. Let's say the initial amount of money deposited in the account is $2. The function represents the balance in the account after a certain amount of time (x years) with an interest rate of 6%. The key features of the function are:

3: This represents the multiplier of the initial investment, indicating that the account balance increases by three times the amount of the initial investment.

1.06: This represents the growth factor due to the 6% interest rate. It is multiplied by the current balance each year.

2: This represents the $2 initial deposit in the account.

To find the percent of decrease from the original price of a video game, subtract the new price from the original price, divide by the original price, and multiply by 100.

To find the percent of decrease from the original price, we can use the formula:

Percent decrease = [(change in price)/(original price)] × 100

Substituting the given values:

Percent decrease = [(49.95 - 45.50)/(49.95)] × 100 = 4.45/49.95 × 100 = 8.9%

Therefore, the percent of decrease from the original price is 8.9%
