Answer:

(2, f(2))

Step-by-step explanation:

f(x) = -3x^2

For point B, the y-coordinate is f(2).

Point B is (2, f(2))

F(x) = -3x^2 is same as
y= -3x^2

To evaluate f(x) = -3x^2 substitue x = 2 which gives you the y coordinate which would be f(2)

Therefore the ordered pair which gives location of point B is

(2, f(2))

What is the value of x in the equation 4x+8y=40 when y=0.8
GREYUIT [131]
Substitute in 0.8 for y.

4x+8y=40 \\ \\ 4x + 8(0.8) = 40 \\ \\ 4x + 6.5 = 40 \\ \\ 4x = 40 - 6.4 \\ \\ 4x = 33.6 \\ \\ x = 8.4 \\ \\

The final result is: x = 8.4.

jason runs 440 yards in 75 seconds.At this rate how many minutes does it take him to run a mile? (1 mile = 1,760 yards)​
Zepler [3.9K]

Answer: 5 minutes

Step-by-step explanation:

We know that 1760 yards are in a mile. We can convert the given info into a proportion. 440/75 = 1760/x, where x is the number of seconds it takes to run a mile. Cross-multiply to get 440x = 75*1760. Divide both sides by 440 to get x = 75*4 = 300 seconds. The problem asks for how many minutes so you have to convert 300 seconds to minutes. To do this, we have to divide 300 by 60 to get 5 minutes.

Express the radical using the imaginary unit i
valentinak56 [21]

Answer:

=\pm i\sqrt{66}

Step-by-step explanation:

So we have:

\pm\sqrt{-66}

This is the same as:

=\pm\sqrt{66\cdot-1}

Separate:

=\pm\sqrt{66}\cdot\sqrt{-1}

Replace the second term with i:

=\pm i\sqrt{66}

The square root of 66 cannot be simplified.

So, this is our answer :)
