Answer:

(-7, 1)

Step-by-step explanation:

Coordinate rules :]

Reflection over x-axis -- (x, y) -> (x, -y)

Reflection over y-axis -- (x, y) -> (-x, y)

Reflection over y = x -- (x, y) -> (y, x)

Reflection over y = -x -- (x, y) -> (-y, -x)

Can you help me solve this please​

Answer:

  180 days

Step-by-step explanation:

The formulas for the volume of a cone and a cylinder are ...

  V = πr²h . . . . . volume of a cone

  V = (1/3)πr²h . . . . . volume of a cylinder

Comparing these formulas, you can see that the 6' high cone at the top will have the same volume as a cylinder of the same radius that is 2' high. So, we can simplify the problem to finding the volume of a cylinder that is 66+2 = 68' high.

  V = π(12 ft)²(68 ft) = 9792π ft³ ≈ 30752.5 ft³

When the corn is used at the rate of 170 ft³/day, it will last ...

  (30752.5 ft³)/(170 ft³/day) ≈ 180.96 days

The corn will last 180 days.

_____

<em>Additional comment</em>

In scenarios like this, it is inappropriate to round up. There will be about 162 ft³ of corn left after 180 days, which is not enough for an additional day.

Please help, i do not get this.
Artyom0805 [142]

Answer:

k(x) = |x - 4| - 2

Step-by-step explanation:

So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.

When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.

Best of Luck!

There are 11 candidates for three postions at a restaraunt. One postion is for a cook. The second position is for a food server
LenaWriter [7]

Answer:

165 combinations possible

Step-by-step explanation:

This is a combination problem as opposed to a permutation, because the order in which we fill these positions is not important.  We are merely looking for how many ways each of these 11 people can be rearranged and matched up with different candidates, each in a different position each time.  The formula can be filled in as follows:

₁₁C₃ = \frac{11!}{3!(11-3)!}

which simplifies to

₁₁C₃ = \frac{11*10*9*8!}{3*2*1(8!)}

The factorial of 8 will cancel out in the numerator and the denominator, leaving you with

₁₁C₃ = \frac{990}{6}

which is 165
