An ant crawls at a rate of 216 ft per minute.
AysviL [449]
First, we need to understand the speed formula:

The time used = distance ÷ rate

In this case, the time needed would be:

5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6

When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:

=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)

Factorize 26 and 13,we get:

=2/5 x 6/1
= 12/5 ft or 2.4 ft

Therefore the answer is 12/5ft or 2.4ft.

Hope it helps!

Find f such that the given conditions are satisfiedf’(x)=x-4, f(2)=-1
kicyunya [14]

Given:

f^{\prime}\left(x\right)=x-4,\text{ and}f\left(2\right)=-1

To find:

The correct function.

Explanation:

Let us consider the function given in option D.

f(x)=\frac{x^2}{2}-4x+5

Differentiating with respect to x we get,

\begin{gathered} f^{\prime}(x)=\frac{2x}{2}-4 \\ f^{\prime}(x)=x-4 \end{gathered}

Substituting x = 2 in the function f(x), we get

\begin{gathered} f(2)=\frac{2^2}{2}-4(2)+5 \\ =2-8+5 \\ =-6+5 \\ f(2)=-1 \end{gathered}

Therefore, the given conditions are satisfied.

So, the function is,

f(x)=\frac{x^{2}}{2}-4x+5

Final answer: Option D
