$\bf 5(x-5)^2-9=6\implies 5(x-5)^2=15\implies (x-5)^2=\cfrac{15}{5}\implies (x-5)^2=3 \\\\\\ \sqrt{(x-5)^2}=\sqrt{3}\implies x-5=\sqrt{3}\implies x=\sqrt{3}+5$

If f(1) = 10 and f '(x) ≥ 3 for 1 ≤ x ≤ 6, how small can f(6) possibly be?

Natalka [10]

Answer:

$f'( x ) = \frac{f(b) - f(a)}{b - a} \\ = \frac{f(6) -f(a)}{6 - 1} \\ 3\leqslant \frac{f(6) - 10}{5} \\ 15\leqslant f(6) - 10 \\ f(6) \geqslant 15 + 10 \\ f(6) \geqslant 25$

What is the value of x?<br><br><br><br> Enter your answer in the box.

Lapatulllka [165]

We can see that

there are six sides

so, n=6

so, firstly we will find total angle

total angle =(n-2)*180

total angle =(6-2)*180

total angle =720

so, sum of all angles must be 720

so, we get

$x+120+100+128+133+112=720$

now, we can solve for x

$x+593=720$

$x=127$ .............Answer

Which expression shows another way to write 36+16?<br> 4(9)+4<br> 4(9+4)<br> 6(6+8)<br> (6+4)(6+4)

allsm [11]

Answer:

36+16= 52

4(9)+4= 40, which does not equal 52.

4(9+4) = 52.

6(6+8) = 84, which does not equal 52.

(6+4)(6+4) = 100, which does not equal 52.

So, 4(9+4) is correct.

Let me know if this helps!
