2. find y'' of y = x(x+2)

y=x²+2x

y'=2x+2

3. find y'' of y = (3x+1)(x-2)

y=3x²+x-6x-2

y=3x²-5x-2

y'=6x-5

4. find y'' of y = (3x+4)squared

y=(3x+4)²

y'=2(3x+4)(3)=6(3x+4)=18x+24

5. find y' of y = 3x-2

y'=3

What is the area of the rectangle?

ch4aika [34]

We have been given a graph having coordinate of 4 points which are : (-2,8), (4,9), (6,-3) and (0,-4).

Question says that they are corner points of the rectangle so we can apply distance formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

to find the lenght and width of that rectangle.

$AB=\sqrt{\left(4--2\right)^2+\left(9-8\right)^2}$

$AB=\sqrt{\left(4+2\right)^2+\left(9-8\right)^2}$

$AB=\sqrt{6^2+1^2}$

$AB=\sqrt{36+1}$

$AB=\sqrt{37}$

$BC=\sqrt{\left(4-6\right)^2+\left(9--3\right)^2}$

$BC=\sqrt{\left(4-6\right)^2+\left(9+3\right)^2}$

$BC=\sqrt{\left(-2\right)^2+12^2}$

$BC=\sqrt{4+144}$

$BC=\sqrt{148}$

$BC=2\sqrt{37}$

Now to find the area we will multiply length (AB) and width (BC)

Area of the rectangle $=\sqrt{37}\cdot2\sqrt{37}$

Area of the rectangle =2*37=74

Hence final answer is 74 square units.

Sarah and Kaylee go to the movie theater and purchase refreshments for their friends. Sarah spends a total of $47.00 on 12 drink

Readme [11.4K]

Answer:

1 drink costs $\$3.25$ and 1 popcorn bag cost $\$8$

Step-by-step explanation:

Given:

Sarah spends a total of $47.00 on 12 drinks and 1 bag of popcorn.

Kaylee spends a total of $81.75 on 3 drinks and 9 bags of popcorn

Let the price of 1 drink be x

Let the price of 1 popcorn bag be y

Sarah Spends is given by:

$12x+y =47$

Kayle spends is given by:

$3x+9y=81.75\\3x= 81.75-9y\\x= \frac{81.75-9y}{3}$

Now putting the value of x in sarah spending equation we get

$12(\frac{81.75-9y}{3})+y=47\\4(81.75-9y)+y =47\\327-36y+y=47\\327-47=35y\\y=\frac{280}{35}=8$

Now Substituting value of y=8 in Sarah spends equation we get

$12x+y=47\\12x+8=47\\12x=39\\x=\frac{39}{12}=3.25$

Hence 1 drink costs $\$3.25$ and 1 popcorn bag cost $\$8$
