Please find the answer to this function! F(2)= 6x^4-10x^3+40x-50

steposvetlana [31]

<u>Answer-</u>

$f(2)= 6x^4-10x^3+40x-50=46$

<u>Solution-</u>

The given function is,

$\Rightarrow f(x)= 6x^4-10x^3+40x-50$

Now, we have to find the value of f(x) at x=2 i.e f(2), so putting x as 2 in the given function,

$\Rightarrow f(2)= 6(2)^4-10(2)^3+40(2)-50$

$\Rightarrow f(2)= (6\times 16)-(10\times 8)+(40\times 2)-50$

$\Rightarrow f(2)= 96-80+80-50$

$\Rightarrow f(2)= 96-50$

$\Rightarrow f(2)= 46$

Therefore, f(2) was found to be 46.

Dana can rent a van for either $80 with unlimited mileage or $45 plus 40 cents per mile. For what numbers of miles traveled woul

myrzilka [38]

Answer:

88 miles.

Step-by-step explanation:

$.40 x 88(miles) = $35.2

$35.2 + $45 = $80.20

Now, the reason it is 88 is because 87 miles would equal

$.40 x 87 = $34.8 (total is $79.80) so that would be $.20 short.

A box contains paper clips of three different sizes. The numbers of each size of paper clip are listed below.

Bond [772]

Answer:

$\frac{7}{10}$

Step-by-step explanation:

Add all paper clip sizes together:

$100 + 250 + 150 = 500$

They want the probability of either a small or medium being chosen, so you add both paper clips sizes together.

$100 + 250 = 350$

Now put the number of small and medium paper clips together over the total number of paper clips to find the probability.

Can divide 350 and 500 by 50, which simplifies it down to 7/10.

$\frac{350}{500} = \frac{7}{10}$
