Answer: 14 1/15

Step-by-step explanation:

4 2/5 + 9 2/3 = 13 + 6/15 + 10/15 = 13 + 16/15 = 14 1/15

the answer is 221/15 = 14 1/15

Step-by-step explanation:

4 2/5 + 9 2/3

= (4+9)+(2/5 +2/3)

= 13+2×3 + 2×5

5×3 3×5

= 13+ 6/15 + 10/15

= 13+ 6+10

= 13+ 16/15

= 13+ 1 1/15

= 14 1/15

Find all critical numbers for the following function. Then use the second-derivative test on each critical number to determine

Gelneren [198K]

Critical values are values where f'(x)=0 and the bounds of a function. Thus, let's solve for f'(x)!

f(x)=2x^3-3x^2+3x+8
f'(x)=6x^2-6x+3

Now let's set f'(x)=0

0=6x^2-6x+3
0=2x^2-2x+1

As it turns out, 2x^2-2x+1 isn't factorable!
This saves me some time because this means there are no critical numbers!

Answer:

$XY=16.2$

Step-by-step explanation:

It is given that the two figures are similar. This means that the ratio between the corresponding sides is equal. In essence, a side in the larger figure over its corresponding side in the smaller figure is equal to another side in the larger figure over its corresponding side in the smaller figure. Therefore, one can set up a proportion and solve to find the unknown side.

$\frac{WX}{ST}=\frac{XY}{TU}$
