A computer can sort x objects in t seconds, as modeled by the function

r-ruslan [8.4K]

Answer:

36 objects

Step-by-step explanation:

You want the value of x when t=9, so you're solving ...

9 = 0.007x^2 +0.003x

9 = 0.007(x^2 + 3/7x)

From here, we observe that an approximation is probably sufficient.

9/0.007 = x(x +3/7) . . . . . the expression on the right is nearly x^2

x ≈ 3/√.007 ≈ 35.9 ≈ 36

We can check:

.007(36)(36 3/7) = 9.18

.007(35)(35 3/7) = 8.68

To keep the computer busy for 9 seconds, it needs to sort 36 objects.

16 POINTS HELP ASAP plzzzzzzzzz

schepotkina [342]

Answer:

$\large\boxed{\large\boxed{\sqrt{3}$

Explanation:

You are comparing irrational numbers.

By inspection, i.e. at first sight you can only compare $\sqrt{3} \text{ }and\text{ } 2\sqrt{3}$ because they have the same radicand.

You can order: $\sqrt{3}$

You can introduce the 2 inside the radical by squaring it:

$2\sqrt{3}=\sqrt{2^2\times3}=\sqrt{12}$

Since 5 is between 3 and 12, you can order:

$\sqrt{3}$

Which is:

$\sqrt{3}$

You must know that π ≈ 3.14.

5 is less than 9 and the square root of 9 is 3; hence, $\sqrt{5}$ and $\sqrt{5}$

Now you must determine whether π is less than or greater than $\sqrt{12}$

Using a calculator or probing numbers between 3 and 4 you get $\sqrt{12} \approx3.46$

Hence, the complete order is:

$\sqrt{3}$

The difference of twice a number and five is three. Find the num

Grace [21]

Answer:

add 5 then multiply by 1/2

Step-by-step explanation:

Twice a number is 2n.

The difference of twice a number and five 2n - 5.

The difference of twice a number and five is three. 2n - 5 = 3

2n - 5 = 3

2n - 5 + 5 = 3 + 5 (1) add 5

2n = 8

1/2*2n = 1/2*8 (2) multiply by 1/2

n = 4
