Guide Questions:
1. How do you saive for the area of the shaded region in figure A?
2. How do you solve for the area of the shaded region in figure B?
3. Is method finding the shaded region in figure A and B the same? Why? or Why not?
please answer on 3 i need answers for that number 3 questions
Answer:
1. The area is found by using the formula for a rectangle
The area is 150 cm²
2. The area is found by the definite integral for the area between two points under a curve
3. The methods are different
The methods are different because the area of figure A is found by the multiplication between the dimensions, while the area of figure B is found by the difference between the values of the integral of the function between the points
Step-by-step explanation:
1. The area of the shaded figure A is found by multiplying the dimensions of the figure, which is the length multiplied by the breadth of the figure
From the question, we have;
The area of the rectangular figure, A = Length × Breadth
The length of the figure = 15 cm
The breadth of the rectangular figure = 10 cm
Therefore, we have;
A = 15 cm × 10 cm = 150 cm²
The area of the rectangular figure, A = 150 cm²
2. The bell shape of the figure B is obtained from a function f(x) as obtained from MIT mathematics website as follows;
[tex]f(x) = e^{-t^2}[/tex]
Therefore the area of the shaded region in the bell shaped figure between the points 0 and 1 on the x-axis is found by integration as follows;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt = \dfrac{1}{2} \cdot \sqrt{\pi} \times erf(t)[/tex]
Using a graphing calculator, we have;
[tex]A = \int\limits^1_0 {e^{-t^2}} \, dt \approx 0.746824[/tex]
3. The method of finding the area of figure A is different from the method of finding the area of the figure B
The methods are different because the area of figure A is the area of the whole figure of a geometric shape with known formula for area while the area of of the shaded region has no predefined formula but is calculated using the calculus for the area under a curve.

Use the distributive property to multiply combine like tems & find the equation
6x(6x+3)-3(6x+3)
Answer:
Solution: 36x2−9
Step-by-step explanation:
So, you always have to start with distrubuting which is basically dividing.
Heres the equation that I started with. You can do it differently of course.
36x2+18x-3(6x+3)
combine like terms.
36x2-9
, your solution will be
36x2-9

Pls help me!!!! Im stuck!!!
Answer:
has no solution.
Step-by-step explanation:
you can see that the two equations are almost identical except for the fact that one is multiplied by 7, but it isnt completely multiplied correctly so there would be no solutions.
Answer:
infinite solutions
Step-by-step explanation:
you can solve this by the elimination method. take the rover a equation and multiply it by -7 and then combine the equations. when you do this, you can see that either side equals 0 which means that there are infinite solutions.
-7(y= 1.5x - 6) which equals the equation below
-7y= -10.5x-42 then combine the other equation
7y=10.5x+42 and that equals
0=0
Write
39
100
as a decimal number
Answer:
0.391.00Step-by-step explanation:
"100% as a decimal is written as 1.00 as decimal notation.""39% = 0.39 in decimal form. Percent means 'per 100'. So, 39% means 39 per 100 or simply 39/100."Tori has a wardrobe that is 7 feet tall, 3 feet wide, and 2 feet long. She wants to buy a new wardrobe that is 7 feet tall, 4 feet wide, and 2 feet long. What is the difference in volume of the two wardrobes? V = ft3
Answer:
14 ft³
Step-by-step explanation:
Previous wardrobe : 7 feet tall, 3 feet wide, and 2 feet long
Volume of previous wardrobe = length × width × height
= 7 ft × 3 ft × 2 ft
= 42 ft³
Volume of previous wardrobe = 42 ft³
New wardrobe: 7 feet tall, 4 feet wide, and 2 feet long
Volume of new wardrobe = length × width × height
= 7 ft × 4 ft × 2 ft
= 56 ft³
Volume of new wardrobe = 56 ft³
What is the difference in volume of the two wardrobes?
Difference in volume of new wardrobe and previous wardrobe = Volume of new wardrobe - Volume of previous wardrobe
= 56 ft³ - 42 ft³
= 14 ft³
Difference in volume of new wardrobe and previous wardrobe = 14 ft³

Find the percent of change in the time to run a
mile from June to September. Round to the
nearest tenth of a percent. (Hint, make sure
change each to seconds first!)
7:45
(5:57
June
September
Answer:
23.225%
Step-by-step explanation:
Runtime in June (x1) = 7:45 = (7 * 60) + 45 = 465
Runtime in September (x2) = 5:57 = (5*60)+57 = 357
Percentage change in Runtime :
[|x2 - x1|÷ x1] * 100%
[|357 - 465| ÷ 357] * 100%
108 / 465 * 100%
0.23225 * 100%
= 23.225%

A sales representative sells a salad
dressing recipe for $620 and gets an
additional $0.15 for each bottle sold.
Write an equation to model the total
payment.
Answer:
620+0.15x=total payment
Step-by-step explanation:
It is the price of the recipe plus the amount the representative gets per bottle sold. Replace x with the number of bottles sold and multiply it by the 0.15. Add the 620 and you get your total.
How can you determine if a situation is asking you to calculate surface area or volume?
Answer:
A situation in which you would need to calculate the surface area or volume of a solid would be when you are going to put up wallpaper in a room. You need to measure the room and the wallpaper. If you wanted to put up moldings on the walls too, than you would need to measure the surface area and volume of the moldings as well so you would know where to cut the wood to fit witht eh wall shape of the room.
