Answer:

x=3

Step-by-step explanation:

Sub y=x-1 into 2x+y=8.

You will get 2x+x-1=8.

Simplify 3x-1=8

Solve 3x=9

x=3

Answer: V ≈ 46.6

The formula for a cylinder with a diameter is: [tex]V=\pi (\frac{d}{2})^2h[/tex]

As that being said, we multiply the diameter with pi, then divide the diameter by 2, then multiply the height.

Remember, pi is 3.14.

π → 3.14

Let's break the equation down.

3.14 × 2.4 / 2 × 10.3.

Let's solve.

3.14 × 2.4 / 2 × 10.3 = 46.5961

We solved the equation, but we aren't done. We round the decimal to the nearest tenth.

To do that, find the 5 in the tenth place and take a look at 9. Round up if the digit to the right is greater or equal to 5. Round down if the digit to the right if less than 5.

Therefore, 9 is greater than 5, so we round up.

46.5961 → 46.6

Hence, 46.6 is the answer.

Answer:

v=46.6

Step-by-step explanation:

ok so the shape of the bottle isn't given, but we can assume that it's a cylinder.

with that, we need to 'find' the formula for the volume of a cylinder-

v=πr²h

now, lets plug in what we know-

we were given the diameter, which is the straight line passing from side to side through the center of a body or figure, especially a circle or sphere. but what we need is the radius, so to find that we'll divide the diameter in half-

2.4/2=1.2

now we can plug in the radius and height-

v=π*1.2²*10.3

v=46.6

good luck :)

i hope this helps

have a nice day!

Answer:

k(x) = 1.20^x

Step-by-step explanation:

Here, we want to get a function

The output in this case refers to k(x)

the input refers to the value x

So, for every 1 increase in x, we want k(x) to increase by 20%

20% is same as 20/100 = 0.2

So at an initial value of 1, each increase if 20% will be 0.2 + 1 = 1.2

So therefore, we have the function as;

k(x) = 1.20^x

b) 220 units

c) 0 units

Answer:

(B) Is the answer here

Step-by-step explanation:

Well a function’s domain can’t repeat no matter what.

Domain is X.

So the first one doesnt work since it repeats to every single digit that exists.

The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.

Answer:

B

Step-by-step explanation:

Hello There!

In order for the relations to be a function the x values may not repeat

For answer choice A the x value -2 repeats multiply times therefore the relation is not a function

For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices

For answer choice C the x values -3 and 2 repeat therefore it is not a function

For answer choice D the x value 2 repeats therefore the relation is not a function

So we can conclude that the correct answer is B

Answer:

(-9,6)

Step-by-step explanation:

The center of a circle represented by the equation is (-9, 6)

The standard equation of a circle is expressed as:

(x- a)^2+(y−b)^2= r^2

where:

r is the radius of the circle

(a, b) is the center

Given the equation of a circle expressed as (x+9)^2+(y−6)^2=10^2, on comparing;

a = -9

b = 6

Hence the center of a circle represented by the equation is (-9, 6)

O: (2,-4)

P: (5, -2)

Step-by-step explanation:

What you would do is find out where the two lines intercross. The 2 right quadrants are positive. The two left are negative. Count the lines and figure out the ordered pair. X is left and right, y is up and down. For example, if you were given a ordered pair, (4,-2) you would go up four, and left 2.
