Answer:

diagram is below
6, 11, 16, 21
s[n] = s[n-1] +5
26, 31, 36

Step-by-step explanation:

a) See below for the next diagram in sequence.

b) The numbers of straws in each diagram are ...

6, 11, 16, 21, ...

c) Each term is 5 more than the previous one, so the recursive rule for the number of straws is ...

s[1] = 6

s[n] = s[n-1] +5

d) The next three terms of the sequence are ...

..., 26, 31, 36, ...

Locate the absolute extrema of the function on the closed interval: y = 3x^(2/3) - 2x, [-1, 1]

Alecsey [184]

To get the extrema, derive the function.
You get y' = 2x^-1/3 - 2.
Set this equal to zero, and you get x=0 as the location of a critical point.
Since you are on a closed interval [-1, 1], those points can also have an extrema.
Your min is right, but the max isn't at (1,1). At x=-1, you get y=5 (y = 3(-1)^2/3 -2(-1); (-1)^2/3 = 1, not -1).
Thus, the maximum is at (-1, 5).

Gertie 3/4 mile.

Sarah 2/4 mile.

Gertie ran farther by: 3/4 - 2/4 = (3 -2)/4 = 1/4

Gertie ran farther by 1/4 mile.

Determine whether the fractions 3 4 and 4 5 are equivalent. Question content area bottom Part 1 Select the correct choice below

VMariaS [17]

Answer: Choice A

The fractions are not equivalent because the product of the numerator of the first fraction and the denominator of the second fraction is  15  , which is not equal to the product of the numerator of the second fraction and the denominator of the first fraction  16 

===================================================

Explanation:

We have the template $\frac{P}{Q} = \frac{R}{S}$ which cross multiplies to $PS = QR$

So if $\frac{3}{4} = \frac{4}{5}$ was true, then $3*5 = 4*4$ must be true as well, and vice versa.

The left side 3*5 turns into 15, while the right hand side 4*4 becomes 16. The 15 and 16 don't match up.

In short, $3*5 = 4*4$ turns into $15 = 16$ which is a false statement. So the original claim that $\frac{3}{4} = \frac{4}{5}$ is also false.
