Answer:

  4096

Step-by-step explanation:

You want to evaluate (-8)⁴.

The exponent of 4 signifies the base (-8) is a factor 4 times in the product:

  (-8)⁴ = (-8)×(-8)×(-8)×(-8)

The multiplication is accomplished in the usual way. There are an even number of minus signs, so the product will be positive. The value is ...

  (-8)×(-8)×(-8)×(-8) = 8·8·8·8 = 64·8·8 = 512·8 = 4096

  (-8)⁴ = 4096

__

Additional comment

It can be faster to decompose the exponent into powers of 2. This makes it possible to use squaring to reduce the number of operations required.

  (-8)⁴ = (8²)² = 64·64 = 4096

2.1 gaallons of honey

Step-by-step explanation:

If you have to istrubute things then its obvous you need to divide something.  To get 19 equally into 9 containers you divide 19 by 9 an get 2.1

I hope this helped

Each jar will have approximately [tex]\( \boxd{2.111 \text{ gallons}} \)[/tex] of honey.

Step 1

To find out how much honey will be in each jar when Jill distributes all of the honey equally among 9 jars, we need to divide the total amount of honey by the number of jars.

Given:

Total amount of honey = 19 gallons

Number of jars = 9

So, to find out how much honey each jar will have, we divide the total amount of honey by the number of jars:

[tex]\[ \text{Amount of honey per jar} = \frac{\text{Total amount of honey}}{\text{Number of jars}} \]\[ \text{Amount of honey per jar} = \frac{19 \text{ gallons}}{9} \]\[ \text{Amount of honey per jar} = \frac{19}{9} \text{ gallons} \][/tex]

Step 2

Now, let's perform the division:

[tex]\[ \text{Amount of honey per jar} = 2.111111 \text{ gallons} \][/tex]

So, each jar will have approximately [tex]\( \boxd{2.111 \text{ gallons}} \)[/tex] of honey.

Each point is placed in a quadrant based on its x and y values. Quadrant I contains points where both values are positive, Quadrant II where x is negative and y is positive, Quadrant III where both are negative and Quadrant IV where x is positive and y is negative

To determine which quadrant a point is located in, recognize that the x-y coordinate plane is divided into four sections called quadrants. The quadrants are numbered I through IV and progress counterclockwise, starting with quadrant I in the upper right corner.

Quadrant I: Both x and y are positive. Quadrant II: x is negative, y is positive. Quadrant III: Both x and y are negative. Quadrant IV: x is positive, y is negative.

Answer:

The answer is 12

Step-by-step explanation:

Step 1:  Convert words into an equation

What do you is you multiply -2 by something to get -24

-2 * something = -24

We can represent something with a variable called x.

-2 * x = -24

-2x = -24

Step 2:  Solve for x by dividing both sides by -2

-2x / -2 = -24 / -2

x = 12

Answer:  The number we can multiply -2 by to get -24 is 12

Lets write this into an expression.

-2x = -24

Now, lets solve for x.

~Divide -2 to both sides

-2x/-2 = -24/-2

~Simplify

x = 12

Answer:

24:6

Step-by-step explanation:

It is 4 to 1. The ratios added up is 5. So 30 divided by 5 is 6. So 1 (the ratio) is 6 games. 4x6=24. So the new ratio is 24 to 6. 24 wins and 6 losses.

The team won 24 games and lost 6, calculated by first solving for x in the equation 5x = 30 and then applying the 4:1 win-to-loss ratio.

If the ratio of wins to losses for Loyola basketball is 4 to 1, and they played 30 games, we want to find how many of those games were wins and how many were losses. Let's say the number of wins is 4x and the number of losses is x. According to the ratio, there are 4 wins for every loss, which makes the total number of games 4x + x = 5x.

Since we know 5x is 30 games, we can solve for x to find out the number of losses. Dividing 30 by 5, we get x = 6. That's the number of losses. To find the number of wins, we multiply 4 times the number of losses (4x), which gives us 4 * 6 = 24 wins.

Answer: About 4 movies

Step-by-step explanation:

1 2/3 times 4/1 = 28/5

28/5 converted to a mixed number is 5 3/5

so therefore it would be ABOUT 4 movies

To find the number of movies that can be downloaded, divide the total downloading time by the time it takes to download one movie. In this case, 15 movies can be downloaded.

To find the number of movies that can be downloaded, we need to divide the total downloading time by the time it takes to download one movie. First, convert the mixed number 5 1/4 to an improper fraction, which is 21/4. Then, multiply 21/4 by the reciprocal of 1 2/5, which is 5/7. This gives us a total of 15 movies that can be downloaded.

Step-by-step explanation:cause u add 3          

A second linear equation that forms a system with exactly one solution with 3x+9y=-8 could be y = -2x + 4, as it has a different slope and y-intercept, ensuring the lines intersect at one point.

To create a system of equations with exactly one solution, you need to write a second linear equation that has a different slope than the first equation (3x+9y=-8) but does not share any points with it. The slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, will be used to construct our new equation.

Given the slope-intercept form y = 9 + 3x as an example, we see that the slope (m) is 3 and the y-intercept (b) is 9. To ensure our second equation has only one solution when paired with the first equation, we can select a different slope and y-intercept. For instance, an equation such as y = -2x + 4 would suffice, as it has a different slope (-2) and intercept (4), ensuring that the two lines will cross at exactly one point on the graph.

In summary, the original equation 3x+9y=-8 and the second equation y = -2x + 4 when graphed will intersect at exactly one point, forming a system of linear equations with one solution. This process involves selecting different values for the slope and y-intercept to make sure the lines are not parallel and do not coincide.

Answer: No

Step-by-step explanation:

When graphing [tex]y=2x+4[/tex] it comes out not being a proportion relationship.

*(revised answer)

So the answer is no, a proportional relationship has to run through the origin, and y=2x+4 has a y-intercept of 4, meaning that even though x increases when y does, the y-intercept means that this equation is not a proportional relationship.

The general equation is given as:

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

[tex]x = \frac{-b}{2a}[/tex]

[tex]x = \frac{0}{2(2)}\\\\x = 0[/tex]

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

[tex]f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1[/tex]

Thus, y coordinate of the vertex is -1

V ≈ 143.91938 ft

volume of the cylinder is 13577335.51 cubic feet

A 3-dimensional solid geometric figure with straight parallel sides and a circular or oval cross section is called a cylinder.

                                             V = πr²h
