Answer:
![V(x)=(11-2x)(12-2x)x= 4 x^3- 46 x^2 + 132 x.](https://tex.z-dn.net/?f=V%28x%29%3D%2811-2x%29%2812-2x%29x%3D%204%20x%5E3-%2046%20x%5E2%20%2B%20132%20x.)
Step-by-step explanation:
Consider the picture attached, which illustrates the process of making the box.
Observe that in figure (2) the sides of the rectangle were both reducing two times the length of the side of the square. Therefore, the sides of the new figure are 12-2x units and 11-2x units, respectively.
In figure (3), when the box is done, we see that its dimensions are 11-2x, 12-2x and x (width, length and high, respectively). Thus, by the formula of the volume of a box, we know that the volume V(x) is given by
Solving the parenthesis, we get that ![V(x)=4 x^3- 46 x^2 + 132 x.](https://tex.z-dn.net/?f=V%28x%29%3D4%20x%5E3-%2046%20x%5E2%20%2B%20132%20x.)
Answer:
Part a) The raisins cost $0.8 per ounce
Part b) 1.25 ounces
Step-by-step explanation:
<u><em>The correct question is</em></u>
Jackson bought 5 ounces of raisins for $4 dollars.
a) How much do raisins cost per ounce?
b) How many ounces of raisins can be bought for $1?
Part a) How much do raisins cost per ounce?
we know that
To find out the unit rate divide the total cost by the total weight
so
![\frac{4}{5} =\$0.8\ per\ ounce](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20%3D%5C%240.8%5C%20per%5C%20ounce)
therefore
The raisins cost $0.8 per ounce
Part b) How many ounces of raisins can be bought for $1?
we know that
The raisins cost $0.8 per ounce
using proportion
Find out how many ounces of raisins can be bought for $1
Let
x -----> the ounces of raisins
![\frac{1}{0.8}=\frac{x}{1}\\\\x= 1.25\ ounces](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B0.8%7D%3D%5Cfrac%7Bx%7D%7B1%7D%5C%5C%5C%5Cx%3D%201.25%5C%20ounces)
- /-49
-/-1 * 7 * 7
-7i
4 - 3i
Go to 4 on the x axis (right)
Go to -3i on the y axis (down)
Your coordinate is (4, -3i)
To graph -3i, it is like 0 - 3i
Your coordinate is (0, -3i)
Answer:
cos = 3/5
sin = 4/5
Step-by-step explanation:
tan=4/3 Q1
if you use Pythagorean theorem
![c {}^{2} = a {}^{2} + b {}^{2} \\ c {}^{2} = 4 {}^{2} + 3 {}^{2} \\ c {}^{2} = 16 + 9 \\ c {}^{2} = 25 \\ c = + - 5 \\](https://tex.z-dn.net/?f=c%20%7B%7D%5E%7B2%7D%20%20%3D%20a%20%7B%7D%5E%7B2%7D%20%20%2B%20b%20%7B%7D%5E%7B2%7D%20%20%5C%5C%20c%20%7B%7D%5E%7B2%7D%20%20%3D%204%20%7B%7D%5E%7B2%7D%20%20%2B%203%20%7B%7D%5E%7B2%7D%20%20%5C%5C%20c%20%7B%7D%5E%7B2%7D%20%20%3D%2016%20%2B%209%20%5C%5C%20c%20%7B%7D%5E%7B2%7D%20%20%3D%2025%20%5C%5C%20c%20%3D%20%20%2B%20%20-%205%20%5C%5C%20)
Becauseof Q1

sin = 4/5
cos = 3/5
