Let R be the triangular region in the first quadrant with vertices at points (0,0), (a,0), and (0,b), where a and b are positive constants. Write dow the volume of the solid generated when region R is revolved about the x-axis?
Answer:
volume of the solid generated when region R is revolved about the x-axis is π ₀∫^a ( [tex]\frac{-b}{a}[/tex]x + b )² dx
Step-by-step explanation:
Given the data in the question and as illustrated in the image below;
R is in the region first quadrant with vertices; 0(0,0), A(a,0) and B(0,b)
from the image;
the equation of AB will be;
y-b / b-0 = x-0 / 0-a
(y-b)(0-a) = (b-0)(x-0)
0 - ay -0 + ba = bx - 0 - 0 + 0
-ay + ba = bx
ay = -bx + ba
divide through by a
y = [tex]\frac{-b}{a}[/tex]x + ba/a
y = [tex]\frac{-b}{a}[/tex]x + b
so R is bounded by y = [tex]\frac{-b}{a}[/tex]x + b and y =0, 0 ≤ x ≤ a
The volume of the solid revolving R about x axis is;
dv = Area × thickness
= π( Radius)² dx
= π ( [tex]\frac{-b}{a}[/tex]x + b )² dx
V = π ₀∫^a ( [tex]\frac{-b}{a}[/tex]x + b )² dx
Therefore, volume of the solid generated when region R is revolved about the x-axis is π ₀∫^a ( [tex]\frac{-b}{a}[/tex]x + b )² dx
The volume of the solid generated when region R is revolved about the x-axis is [tex]\frac{b^{5} }{3a^{2} }[/tex].
Equation of the line AB
[tex]y-0 = \frac{b-0}{0-a} (x-a)[/tex]
[tex]y = \frac{-b}{a} (x-a)[/tex]
What is the volume generated when a curve f(x) is generated about the x-axis?The volume generated when a curve f(x) is rotated about the x-axis in x∈(c,d) is given by:
[tex]V=\int\limits^d_c {y^2} \, dx[/tex]
So, the volume generated when line AB is rotated about the x-axis will be [tex]V=\int\limits^b_0 ({\frac{-b}{a} (x-a))^2} \, dx[/tex]
[tex]V=\frac{b^{5} }{3a^{2} }[/tex]
Therefore, the volume of the solid generated when region R is revolved about the x-axis is [tex]\frac{b^{5} }{3a^{2} }[/tex].

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.
A) 7.2
B) 6.0
C) 2.8
D) 6.3
Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
Step-by-step explanation:
Given
L(3,4)M(1,-2)Determining the length of LM
(x₁, y₁) = (3, 4) (x₂, y₂) = (1, -2)The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)
[tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]
[tex]=\sqrt{2^2+6^2}[/tex]
[tex]=\sqrt{4+36}[/tex]
[tex]=\sqrt{40}[/tex]
[tex]=\sqrt{4\times 10}[/tex]
[tex]=\sqrt{2^2\times \:10}[/tex]
[tex]=2\sqrt{10}[/tex]
[tex]=6.3[/tex]
Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
Darius has a 6-month loan for $500. He must pay 5.6% annual interest on the loan. Using the formula for simple interest, I = Prt, where I is interest owed, P is the amount borrowed, r is the rate as a decimal, and t is time in years, find the amount of interest owed by Darius after 6 months.
The amount of interest that's owed by Darius after 6 months will be $14
Principal = $500
Rate = 5.6%
Time = 6 months.
Based on the information given, the simple interest will be calculated as:
Simple Interest = PRT/100
Simple Interest = ($500 × 5.6 × 1/2) / 100
Simple Interest = $1400/100
Simple Interest = $14
Therefore, the amount of interest that's owed by Darius after 6 months will be $14

Write an equation of the line in slope-intercept form.
Answer:
y = 2x+3
Step-by-step explanation:
You can see that the line crosses the y-axis at (0,3), so the y-intercept is 3.
To find the slope, compare the coordinates of the two points marked on the line, (0,3) and (-3,-3).
slope = Δy/Δx = ((-3)-3)/((-3)-0) = (-6)/(-3) = 2
Slope-intercept equation for line of slope 2 and y-intercept 3:

GUYS I NEED HELP PLSSSSSS! Ive been working on this ALL day!
First, let's write what we know.
We can represent the number of students in the play from each class as L, G, and C. We know that L = 7, and if Gardener has 4 more students than Cho, then G = C + 4.
Then, taking the third line, we can write an inequality:
C < L < G
C < 7 < C + 4
C - 4 < 3 < C
3 < C < 7
If C is greater than 3 and less than 7 and is an integer, than means C is 4, 5, or 6.
Then, we need to find how many students are in the play.
C + L + G
C + 7 + C + 4
2C + 11
So we have our expression for the number of students in the play. Then, we need to find the total number of students. We know that 2C + 11 will be 30% of the total, so if T is the total, we can find T.
0.3T = 2C + 11
(Divide by 3/10 or multiply by 10/3 on both sides)
T = 20/3 C + 110/3
We know from before that C is 4, 5 or 6. We can plug these into our equation here to find which one produces a whole number.
T = 20/3 * 4 + 110/3
T = 190/3
T = 20/3 * 5 + 110/3
T = 210/3
T = 70
T = 20/3 * 6 + 110/3
T = 230/3
We can see here that only when C is 5 will the total be a whole number. That means Mrs. Cho has 5 students in the play. If Mrs. Gardner has 4 more than that, she has 9 students in the play in her class. We now need to figure out the number of student in her class.
The total students are Cho's, Logan's, and Gardner's classes added together. We know that Logan's class is 23 students, so if we subtract that from the total, we can see that Cho's and Gardner's class have 47 students. If Mrs. Cho has 24 students in her class, we can subtract that from the 47, so we know that Mrs. Gardner has 23 students in her class.
Describe the possible lengths of the third side of the triangle given that the lengths of the other two sides are 12 feet and 18 feet.
I attached the picture too.
Answer:
6 ft < L₃ < 30 ft
Step-by-step explanation:
To obtain the answer to the question given above, we must bear in mind that:
The sum of the length of two sides of any triangle is always greater than the 3rd length i.e
L₁ + L₂ > L₃
With the above information in mind, we can obtain the answer to the question given above as follow:
Length 1 (L₁) = 12 feet
Length 2 (L₂) = 18 feet
Length 3 (L₃) =..?
Case 1:
L₁ + L₂ > L₃
12 + 18 > L₃
30 > L₃
L₃ < 30 feet
Case 2:
L₁ + L₃ > L₂
12 + L₃ > 18
Collect like terms
L₃ > 18 – 12
L₃ > 6 feet
Thus,
6 feet < L₃
Combining case 1 and 2,we obtained:
6 ft < L₃ < 30 ft
Therefore, the possible Lenght of the 3rd side is : 6 ft < L₃ < 30 ft
Ms. Hagan invested twice as much money in an account that pays 7% interest as she did in an account that pays 6% in interest. Her total investment pays her $1,000 a year in interest. How much did she invest at each rate?
Answer: She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.
Step-by-step explanation:
Let P be the initial amount she invested in an account that pays 6% interest.
Then, amount invested in other account = 2P
Simple interest = Principal x rate x time
After one year, for the first account,
Interest = P(0.06)(1) = 0.06P
For second account,
Interest = (2P)(0.07)(1)=0.14P
Total interest = [tex]0.06P+0.14P=1000[/tex]
[tex]\Rightarrow\ 0.20P=1000\\\\\Rightarrow\ P=\dfrac{1000}{0.20}\\\\\Rightarrow\ P=5000[/tex]
2P = 2(5000)=10000
Hence, She invested $5000 in an account that pays 6% interest and $10000 in an account that pays 7% interest.
At the interest rate of 6%, amount invested is; $5000
At interest rate of 7%, amount invested is; $10000
Let P be the initial amount that Ms. Hagan invested in the 6% interest account that
Since she invested twice as much in the 7% interest account as in the 6% interest account, then;
Initial amount invested in the 7% interest account = 2P
Formula for Simple interest is;
I = Principal × rate × time
Interest after 1 year for the 6% interest account is,
I_1 = P × 0.06 × 1
I_1 = 0.06P
Interest after 1 year for the 7% interest account is,
I_2 = 2P × 0.07 × 1
I_2 = 0.14P
Total investment pays her $1000 after a year. Thus;
0.06P + 0.14P = 1000
0.2P = 1000
P = 1000/0.2
P = $5000
Then amount initially invested in the 7% interest account = 2P = $10000
