Answer:

164 square inches

Step-by-step explanation:

You can compute the area by adding the areas of the 4 corner triangles, the 4 side rectangles and the central square.

The area of the triangle is ...

A = (1/2)bh = (1/2)(4 in)(4 in) = 8 in²

The area of a rectangle is ...

A = LW = (6 in)(4 in) = 24 in²

The area of the central square is ...

A = s² = (6 in)² = 36 in²

Then the total area is ...

4(8 in²) +4(24 in²) +36 in² = (32 +96 +36) in² = 164 in²

Alternatively, you can draw a 14-inch square around the whole figure, then subtract the areas of the four corner triangles that are not part of the octagon. The area computed that way would be ...

(14 in)² - 4((1/2)(4 in)(4 in)) = 196 in² -32 in² = 164 in²

A new DVD is available for sale in a store one week after its release. The cumulative revenue, $R, from sales of the DVD in this

AnnyKZ [126]

Solution :

It is given that :

$f'(t) = (350 \ln t)'$

$=350(\ln t)'$

$=\frac{350}{t}$

So, $f(5)=350 \ln (5) \approx 563$

$f'(5) = \frac{350}{5}$

$=70$

The relative change is then,

$\frac{f'(5)}{f(5)}=\frac{70}{350\ \ln(5)}$

$=\frac{1}{5\ \ln(5)}$

$\approx 0.12$

$=12\%$

This means that after 5 weeks, the revenue from the DVD sales in $563 with a rate of change of $70 per week and the increasing at a continuous rate of 12% per week.

5y + 2 + 6 + 2y 5y + 2(y + 3) + 2 combining like terms 6y − y + 2y + 10 − 4 + 2 Commutative Property Distributive Property arrow

Paraphin [41]

Answer:

Distributive Property

Step-by-step explanation:

5y + 2 + 6 + 2y

= 5y + 2(y + 3) + 2 This is the distributive property of multiplication w.r.t. addition

= 6y − y + 2y + 10 − 4 + 2

The distributive property of multiplication with respect to addition is the one which separates each term by using multiplication and then addition.

So we see that 2 is multiplied with y and 3 and then added with the like terms. If there was a minus sign the property would be distributive over subtraction.
