A circle has a radius of 6x^9y^5 cm, what is the area of this circle in square centimeters
Answers
[tex]\text {Area of circle }= \pi (6x^9y^5)^2 \text{ cm}^2[/tex]
[tex]\text {Area of circle }= 12\pi x^{18}y^{10} \text{ cm}^2[/tex]
The area of the circle in square centimeters is [tex]\( 36\pi x^{18}y^{10} \)[/tex] cm².
The area of a circle is given by the formula [tex]\( A = \pi r^2 \)[/tex], where [tex]\( r \)[/tex] is the radius of the circle.
Given that the radius [tex]\( r \)[/tex] of the circle is [tex]\( 6x^9y^5 \)[/tex] cm, we can substitute this value into the formula to find the area.
[tex]\( A = \pi (6x^9y^5)^2 \)[/tex]
Now, we square the radius:
[tex]\( (6x^9y^5)^2 = (6x^9y^5)(6x^9y^5) \)[/tex]
[tex]\( = 36x^{18}y^{10} \)[/tex]
Substituting this back into the area formula:
[tex]\( A = \pi \cdot 36x^{18}y^{10} \)[/tex]
[tex]\( A = 36\pi x^{18}y^{10} \)[/tex]
Therefore, the area of the circle in square centimeters is [tex]\( 36\pi x^{18}y^{10} \)[/tex] cm².
Suppose angle A is complementary to angle B, and angle B is supplementary to angle C. If measure of angle A is 21 degree, find measure of angle C.
Answers
Since A and B are complementary they add to 90. So we know that B must be 69 degrees.
Since B and C are supplementary they add to 180. So we know that C must be 111.
In solving this problem, we first identify that angle B is 69 degrees as it is complementary to 21-degree angle A (adding to 90 degrees). Then, we find angle C to be 111 degrees as it is supplementary to angle B (adding to 180 degrees).
Explanation:In this problem, we are told that angle A (measuring 21 degrees) is complementary to angle B. Complementary angles are angles that add up to 90 degrees. So, we can find the measurement of angle B by subtracting the measurement of angle A from 90 degrees, which gives us 90 - 21 = 69 degrees for angle B.
Next, we are told angle B is supplementary to angle C. Supplementary angles are angles that add up to 180 degrees. So, we can find the measurement of angle C by subtracting the measurement of angle B from 180 degrees, which results in 180 - 69 = 111 degrees for angle C.

How do you determine if two probabilities are conditional to each other?
Please help
Answers
Final answer:
You can determine if two probabilities are conditional by checking if the occurrence of one affects the probability of the other. If it does, the probability is conditional, represented by P(A|B), otherwise, the events are independent.
Explanation:
Determining Conditional Probabilities
To determine if two probabilities are conditional to each other, you consider if the occurrence of one event affects the probability of the other event happening. The conditional probability of event A given event B is denoted by P(A|B). This is calculated by dividing the probability of both events A and B occurring together (P(A AND B)) by the probability of event B:
P(A|B) = P(A AND B) / P(B)
This formula is applicable only when P(B) is greater than zero, meaning event B must have a chance of occurring. If the probability of A happening does NOT change whether B occurs or not, then A and B are independent events. Conversely, if the probability of A does depend on the occurrence of B, then A and B are dependent, and the probability P(A|B) is a conditional probability.
Independence is defined as the situation where the probability of A and B occurring together is the product of their individual probabilities (P(A) * P(B)). If this is true, P(A|B) would simply be P(A), as B's occurrence doesn't affect A's probability.

The diameter of a circle is 18 cm. What is its area in terms of π.
Answers
Answer:
Area, [tex]A=(81\pi )\ cm^2[/tex]
Step-by-step explanation:
Given that,
The diameter of the circle, d = 18 cm
The radius of a circle is half of its diameter, r = 9 cm
The formula to find the area of a circle is given by :
[tex]A=\pi r^2[/tex]
When r = 9 cm
[tex]A=\pi (9\ cm)^2[/tex]
[tex]A=(81\pi )\ cm^2[/tex]
So, the area of the circle is [tex](81\pi )\ cm^2[/tex]. Hence, this is the required solution.
The area of a triangle is 30 square feet. If the height of the triangle is 5 feet, what is the base of the triangle? 12 ft 6 ft 3 ft 24 ft
Answers
30=(1/2)*base*5
6=(1/2)*base
base=12 ft
To find the base of the triangle with a known area and height, apply the formula for the area of a triangle and solve for the base, resulting in 12 ft.
The base of the triangle can be found using the formula for the area of a triangle:
Area = 1/2 × base × heightGiven the area is 30 sq ft and height is 5 ftSubstitute the values: 30 = 1/2 × base × 5Solve for base: base = 30 / (1/2 × 5) = 30 / 2.5 = 12 ftHey can you please help me posted picture of question
Answers
Explanation:
Since, rolling a die and tossing a coin are independent events, the sample space of both events is the product of the outcomes for each event, i.e 6 × 2 = 12.
You can check that here:
roll a die toss a coin
1 head
1 tail
2 head
2 tail
3 head
3 tail
4 head
4 tail
5 head
5 tail
6 head

The number of acres of wetland infested by an invasive plant species after t Years is given by u(t)=12•2^t/3. Solve the equation u(t)=50. What does your answer tell you about the wetland?
Answers
u (t) = 12 • 2 ^ t / 3
We equate the equation for u (t) = 50.
We have then:
12 • 2 ^ t / 3 = 50
We clear the value of t:
2 ^ t / 3 = 50/12
log2 (2 ^ t / 3) = log2 (50/12)
t / 3 = log2 (50/12)
t = 3 * log2 (50/12)
t = 6.2 years

Find the shaded area of the basketball court to the nearest foot.
Answers
Rectangle - 12*19 = 228
Half a circle - [tex]\pi r^2 = \pi 6^2 = 36 \pi/2 = 18 \pi [/tex]
In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36[tex] \pi [/tex]
Then find the area of the semi-circle above it, which is pi times the radius squared. The diameter is 12ft, and we know the radius is half of the diameter, so the radius is 6ft. Our equation is pi times 6^2, or pi times 36.
We’ll just make pi 3.14, so 36•3.14=113.04 feet.
Add the area of the semi-circle and the rectangle together to get one of the shaded areas. 228+113.04= 341.04.
Now that we know the full area of one shaded region, we multiply it by two because there’s two of them. 341.04•2= 682.02.
Since we round it to the nearest foot, our final answer is that the shaded area of the basketball court is 682 square feet.
A tank contains 30 lb of salt dissolved in 300 gallons of water. a brine solution is pumped into the tank at a rate of 3 gal/min; it mixes with the solution there, and then the mixture is pumped out at a rate of 3 gal/min. determine a(t), the amount of salt in the tank at time t, if the concentration of salt in the inflow is variable and given by cin(t) = 2 + sin(t/4) lb/gal.
Answers
[tex]\implies A'(t)=\dfrac{3\text{ gal}}{1\text{ min}}\cdot\left(2+\sin\dfrac t4\right)\dfrac{\text{lb}}{\text{gal}}-\dfrac{3\text{ gal}}{1\text{ min}}\cdot\dfrac{A(t)\text{ lb}}{300+(3-3)t\text{ gal}}[/tex]
[tex]A'(t)+\dfrac1{100}A(t)=6+3\sin\dfrac t4[/tex]
We're given that [tex]A(0)=30[/tex]. Multiply both sides by the integrating factor [tex]e^{t/100}[/tex], then
[tex]e^{t/100}A'(t)+\dfrac1{100}e^{t/100}A(t)=6e^{t/100}+3e^{t/100}\sin\dfrac t4[/tex]
[tex]\left(e^{t/100}A(t)\right)'=6e^{t/100}+3e^{t/100}\sin\dfrac t4[/tex]
[tex]e^{t/100}A(t)=600e^{t/100}-\dfrac{150}{313}e^{t/100}\left(25\cos\dfrac t4-\sin\dfrac t4\right)+C[/tex]
[tex]A(t)=600-\dfrac{150}{313}\left(25\cos\dfrac t4-\sin\dfrac t4\right)+Ce^{-t/100}[/tex]
Given that [tex]A(0)=30[/tex], we have
[tex]30=600-\dfrac{150}{313}\cdot25+C\implies C=-\dfrac{174660}{313}\approx-558.02[/tex]
so the amount of salt in the tank at time [tex]t[/tex] is
[tex]A(t)\approx600-\dfrac{150}{313}\left(25\cos\dfrac t4-\sin\dfrac t4\right)-558.02e^{-t/100}[/tex]
To determine the amount of salt in the tank at time t, we need to consider the inflow and outflow of the brine solution over time. The inflow rate is given as 3 gal/min, and the concentration of salt in the inflow varies with time according to the equation cin(t) = 2 + sin(t/4) lb/gal. The outflow rate is also 3 gal/min.
Explanation:To determine the amount of salt in the tank at time t, we need to consider the inflow and outflow of the brine solution over time. The inflow rate is given as 3 gal/min, and the concentration of salt in the inflow varies with time according to the equation cin(t) = 2 + sin(t/4) lb/gal. The outflow rate is also 3 gal/min.
To find the amount of salt in the tank at time t, we need to integrate the product of the inflow rate and the concentration of salt over the interval [0, t]. This will give us the total amount of salt that has entered the tank up to time t. We can then subtract the amount of salt that has been pumped out of the tank over the same interval to get the amount of salt remaining in the tank at time t.
a(t) = ∫[0,t] (3 gal/min * cin(t)) dt - 3 gal/min * t.
The average value of y=v(x) equals 4 for 1≤x≤6, and equals 5 for 6≤x≤8. what is the average value of v(x) for 1≤x≤8 ?
Answers
Area = 4*(6 -1) +5(8 -6) = 30
Width = 8 - 1 = 7
Average value = 30/7 = 4 2/7
The average value of v(x) for the interval 1≤x≤8 is calculated by summing up the products of the average values each times their respective lengths of interval, and dividing by the total length of the interval, which results in 4.2857 approximately.
Explanation:The average value of v(x) for 1≤x≤8 can be calculated using the formula for the average of a function over an interval, which is the sum of the function values times their respective lengths of interval, divided by the total length of the interval. For the first interval, 1≤x≤6, the average value of y is 4, and the length of the interval is 6-1=5. Hence, the sum of the product of the average value times the length of the interval is 4*5=20.
For the second interval, 6≤x≤8, the average value of y is 5, and the length of the interval is 8-6=2. Hence, the sum of the product of the average value times the length of the interval is 5*2=10.
Summing up these two products, we get 20+10=30. The total length of the overall interval 1≤x≤8 is 8-1=7. Hence, the average value of v(x) for 1≤x≤8 is 30/7=4.2857, approximately.
