Answer:

f(-2) =8

Step-by-step explanation:

f(x) = 3x^2+x-2

Let x = -2

f(-2) = 3 * (-2)^2 + (-2) -2

       = 3(4) -2 -2

If you can walk 3 1/3 miles in an hour, how many miles can you walk in 30 minutes, given the
Vedmedyk [2.9K]

Answer:

d = 1.67 miles

Step-by-step explanation:

Given that,

Speed of a person,  s=3\dfrac{1}{3}\ mph

We need to find how many miles can you walk in 30 minutes, given the  same pace.

30 minutes = 0.5 h

3\dfrac{1}{3}\ mph = \dfrac{10}{3}\ mph

Speed = distance/time

d=v\times t\\\\d=\dfrac{10}{3}\ mph\times 0.5\ h\\\\d=1.67\ miles

So, the person will cover a distance of 1.67 miles

Which shows how to best estimate the product of 4.73 x 8.92?
Anettt [7]

Answer:

5 x 9 = 45

Step-by-step explanation:

A good way to estimate this would be rounding to the nearest whole number.

First we'll look at 4.73. If we're rounding to the nearest whole number, then that means we'll look at the digit one place to the right of 4. The digit to the right of 4 is 7. 7 is greater than 5 so we round up. We get 5. If we do the same for the other number we see that it also gets rounded up to 9. So our new equation is: 5 x 9. That is a simple multiplication equation and when we multiply we get 45.

Hope this helped!
