a box with no top is constructed from a 10 inch x 12 inch piece of cardboard by cutting out congruent squares from each corner of the cardboard and then folding the resulting tabs. We determined the volume of that box (in cubic inches) is given by V(x) = 4x³ - 44x² + 120x where x denotes the length of the side of the square which is removed from each corner (in inches), 0 < x < 5. Solve the inequality V(x)≥80 analytically and interpret your answer in the context of that example.

The figure shows eight congruent triangles made by dividing a square that has an area of 64 cm2. What is the area of ABH? A. 20 cm2

B. 16 cm2

C. 8 cm2

D. 6 cm2

E. 4 cm2

Answers

The answer is C) 8 cm squared.

That is because 64/8 = 8 cm squared. Hope this helps!!!

Answer:

C. 8 cm2

Step-by-step explanation:

If the big square is 64 cm2, then each side is 8 cm (8cm x 8cm = 64 cm2)

Each of the small squares then has both sides of half the side of the big one, then, each small square has 4cm x 4cm = 16 cm2

Ihen, each small triangle's area (such as ABH) is (b.h)/2, being the base and the height equal to the sides of the small square. Each small triangle is (4cm x 4cm)/2=8cm2

Which value of K will make x^2-1/4x+k a perfect square trinomial?

Answers

For this case we have the following polynomial:
$x^2 - (1)/(4)x + k$
We suppose that we have a standard equation of the form:
$ax ^ 2 + bx + c$
To make a perfect square trinomial, we need to complete the square.
Therefore, the value of c is:
$c = ((b)/(2))^2$
Using this definition for this case, we have:
$k = (((-1)/(4))/(2))^2$
$k= ( (-1)/(8) )^2$
$k = (1)/(64)$
Therefore, the perfect square trinomial is:
$x^2 - (1)/(4)x + (1)/(64)$
Answer:
The value of k is:
$k = (1)/(64)$

1/64, because (-1/4)/2 is -1/8, and -1/8 ^2 is 1/64

Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?

Answers

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

Sales tax = 11% * original price = 0.11 * x= 0.11x
Tips for dinner = 20% * original price = 0.20 * x = 0.2x
0.11x + 0.2x = 18.60
0.31x = 18.60
x = 60
$60 was the price of Zoe's dinner, before sales tax and tip.

Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

1. Sales tax = 11% times original price = 0.11 times x= 0.11x

2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x

3. 0.11x + 0.2x = 18.60

4. 0.31x = 18.60

5. x = 60

6. $60 was the price of Zoe's dinner, before everything else

From its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position?

Answers

the first position is at rest, that is 0 seconds, then it goes one direction up to 0.75 seconds and starts returning to original position, it reaches original position again at 1.5 seconds, and goes in the opposite direction up to 2.25 seconds, then starts returning and hits original position once again at 3 seconds
