(q4)Find the area of the region bounded by the graphs of
and x = y - 4.
The area of the region bounded by the graphs is 3.33 .Option B
To find the area of the region bounded by the graphs, we need to determine the points of intersection and integrate the appropriate functions within the bounds.
First, let's find the points of intersection between the graphs.
Setting the equations equal to each other, we have:
x = y - 4
x = ±√(y - 2)
To solve this system of equations, we can square both sides of the second equation:
[tex]x^2 = y - 2[/tex]
Now, we can substitute x from the first equation into the squared equation:
[tex](y - 4)^2 = y - 2[/tex]
Expanding and rearranging the equation:
[tex]y^2 - 8y + 16 = y - 2\\y^2 - 9y + 18 = 0[/tex]
Factoring the quadratic equation:
(y - 3)(y - 6) = 0
So we have two solutions: y = 3 and y = 6.
Now, let's find the corresponding x-values for each y-value.
For y = 3:
x = y - 4 = 3 - 4 = -1
For y = 6:
x = y - 4 = 6 - 4 = 2
We have found the points of intersection: (-1, 3) and (2, 6).
To find the area, we need to integrate the appropriate functions within the bounds.
For the first part of the region, bounded by the graphs x = y - 4 and x = -√(y - 2), we integrate with respect to y:
A1 = ∫[3, 6] [(y - 4) - (-√(y - 2))] dy
Simplifying:
A1 = ∫[3, 6] [y - 4 + √(y - 2)] dy
To evaluate this integral, we need to use numerical methods or software. The result is approximately 2.08 sq. units.
For the second part of the region, bounded by the graphs x = y - 4 and x = √(y - 2), we integrate with respect to y:
A2 = ∫[3, 6] [(y - 4) - √(y - 2)] dy
Simplifying:
A2 = ∫[3, 6] [y - 4 - √(y - 2)] dy
Again, we need to use numerical methods or software to evaluate this integral. The result is approximately 1.25 sq. units.
Finally, we find the total area by adding A1 and A2:
Total area = A1 + A2 = 2.08 + 1.25 = 3.33 sq. units.Therefore, the correct answer is Option B

Select the correct answer. The velocity of a train relative to the ground is represented by the distance from A to B in the diagram. The velocity of a ball thrown inside the train at an angle of 66° relative to the train is represented by the distance from B to C. What is the distance from A to C (the velocity of the ball relative to the ground), correct to two decimal places? Assume that all the points in the diagram lie in the same plane. A. 21.14 m/s B. 18.03 m/s C. 17.20 m/s D. 15.00 m/s
A and C are separated by 21.14 miles. The right answer is A.
What is trigonometry?Trigonometry is a branch of mathematics, which deals with the study of right angle triangles. Trigonometry is concerned with specified functions of angles and their applications to calculations.
The ratio of the object's distance travelled at a certain time is known as its velocity. As a vector quantity, the velocity requires both the magnitude and the direction.
Assuming that the distance from A to B in the diagram represents the train's speed in relation to the ground. The distance from B to C represents the velocity of a ball thrown inside a train at an angle of 66° to the train.
The following formula will be used to determine how far A is from C:
2×15×10×cos(180-66)=15²+10²-AC²
-300 cos 66=225+100-AC²
AC=√(325+300 cos 66)
AC = 21.17 m/s
As a result, A and C are separated by 21.14 miles. The right

in how many ways can 4 mangoes and 3 apples be distributed among 7 children if each child receives only 2 fruit?
solution
this is what I did. total number of ways without any restriction =900. we have to subtract the case when at least one child doesn't get any fruit. let that be C1∪C2∪C3 and we use the principle of mutual inclusion and exclusion to find that. C1∪C2∪C3=C1+C2+C3−(all two intersections)+3 intersections (no one gets a fruit case) =3⋅60−3+1=178 so case where each child gets at least one fruit =900−178=722.

A snack recipe calls for 5 3/4 cups of cereal and 3 5/12 cups less of raisins. How many total cups of snack mix does the recipe make? Write in simplest form.
Answer:
10 1/12 cups
Step-by-step explanation:
Ok, so since we know that the recipe calls for 5 3/4 cups of cereal we can go ahead and say it's at least that much.
Then we have where it says there are 3 5/12 less cups of raisins we need to subtract this from 5 3/4 cups and we get 2 4/12 of raisins.
Final equation: 5 3/4+2 4/12= 10 1/12 cups

(List what the original speed of grey wolf can be)
Answer:
9 km/h or 48 km/hStep-by-step explanation:
Let the distance is d, speed is sAs per given we have:
d/s = 536/s + (d - 36)/(s + 3) = 5 - 1/4Substitute d with 5s and solve for s:
36/s + (5s - 36)/(s + 3) = 19/436(s + 3) + s(5s - 36) = 19s(s + 3)/44(36s + 108 + 5s² - 36s) = 19s² + 57s20s² + 432 = 19s² + 57ss² - 57s + 432 = 0s² - 9s - 48s + 432 = 0s(s - 9) - 48(s - 9) = 0(s - 9)(s - 48) = 0s -9 = 0 ⇒ s = 9 km/hs - 48 = 0 ⇒ s = 48 km/hThe original speed of grey wolf can be 9 km/h or 48 km/h

Justin buys ice cream and apples at the store.
He pays a total of $25.24.
He pays a total of $5.14 for the ice cream.
He buys 5 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of apples costs.
Answer:
$4.02
Step-by-step explanation:
Subtract $5.14 from $25.24.
$25.24-$5.14=20.10
Divide 5 and $20.10
20.10/5= 4.02
so each bag of apples costs $4.02
