evaluate the integral. π/2 ∫ sin^3 x cos y dx y
The value of the integral is -1/4 times the integral of cos(y) over the interval [0, π], which is 0 since the cosine function is periodic with period 2π and integrates to 0 over one period.
To evaluate the integral ∫sin^3(x) cos(y) dx dy over the region [0, π/2] x [0, π], we integrate with respect to x first and then with respect to y.
∫sin^3(x) cos(y) dx dy = cos(y) ∫sin^3(x) dx dy
= cos(y) [-cos(x) + 3/4 sin(x)^4]_0^(π/2) from evaluating the integral with respect to x over [0, π/2].
= cos(y) (-1 + 3/4) = -1/4 cos(y)
Therefore, the value of the integral is -1/4 times the integral of cos(y) over the interval [0, π], which is 0 since the cosine function is periodic with period 2π and integrates to 0 over one period. Thus, the final answer is 0.

Fill in the missing numbers to complete the linear equation that gives the rule for this table.x: 0, 1, 2, 3y: 3, 17, 31, 45Y = ?x + ?
ANSWER
y = 14x + 3
EXPLANATION
We have the table that gives the values of x and y.
We want to find the linear equation that describes the data.
The general form of a linear equation is:
y = mx + c
where m = slope
c = intercept
So, we have to find the slope of the equation first.
We do that by using:
\(m\text{ = }\frac{y2\text{ - y1}}{x2\text{ - x1}}\)where (x1, y1) and (x2, y2) are two sets of data from the table.
Let us pick (x1, y1) as (0, 3) and (x2, y2) as (2, 31)
So, we have that:
\(\begin{gathered} m\text{ = }\frac{31\text{ - 3}}{2\text{ - 0}} \\ m\text{ = }\frac{28}{2} \\ m\text{ = 14} \end{gathered}\)Now, we use the point-slope method to find the equation:
y - y1 = m(x - x1)
=> y - 3 = 14(x - 0)
y - 3 = 14x
=> y = 14x + 3
That is the equation.

Answer:
y = 122.57
Explanation:
y = 143 when x = 49
Y varies directly with x, so the equation is --> y = kx (k would be the constant of variation).
k = y/x = 143/49
y = (143/49) x
When x = 42 --> y = (143/49) · 42 --> y = 2.92 · 42 --> y = 122.57

Area of figure 2 = 150 square cmWX = 25/6 cm (exact)WX = 4.167 (approximate)It's not clear which version of WX your teacher wants, so I provided both of them.
============================================================
Explanation:
Focus on the perimeters. The jump from 36 to 30 means the linear scale factor is 30/36 = 5/6
This means,
WX/YZ = 5/6
WX/5 = 5/6
6WX = 5*5
6WX = 25
WX = 25/6 which is exact
WX = 4.167 approximately
---------------
The linear scale factor is 5/6, so the area scale factor is (5/6)^2 = 25/36.
The area of figure 1 is 216 cm^2, making the area of figure 2 to be 216*(25/36) = 150 cm^2

Which combination correctly pairs a vector quantity with its corresponding unit?(1) weight and kg(2) velocity and m/s(3) speed and m/s(4) acceleration and m2/s
The correct pairing is (2) velocity and m/s , weight is a scalar quantity measured in newtons (N), not kilograms (kg)
Weight is the force experienced by an object due to gravity and is measured in newtons, not the unit of mass which is kilograms.
Velocity is a vector quantity that measures the rate at which an object changes its position. It is defined as the displacement of an object divided by the time taken and is measured in meters per second (m/s).
Speed is the magnitude of velocity and is also measured in meters per second (m/s). It represents how fast an object is moving regardless of its direction. Speed is a scalar quantity, not a vector quantity.
Acceleration is a vector quantity that measures the rate of change of velocity. It is defined as the change in velocity divided by the time taken and is measured in meters per second squared (m/s^2).
Acceleration represents how quickly an object's velocity is changing. Therefore, the correct pairing is (2) velocity and m/s.

Kayla bought 8 hot dogs and hamburgers for her and her friends. Hot dogs cost $1.50 and hamburgers cost $1.75. If she spent a total of $13.25, how many hot dogs did she buy?
Answer:
5 hamburgers and 3 hot dogs
Step-by-step explanation:
D = number of hot dogs
H = number of hamburgers
D + H = 8 then D = 8 - H
1.50D + 1.75H = 13.25
substitute for D
1.50(8-H) + 1.75H = 13.25
12-1.50H + 1.75H = 13.25
subtract 12 from each side
-1.50H + 1.75H = 1.25
0.25H = 1.25
divide both sides by 0.25
H = 5
D = 8-5
D = 3

What are 3 consecutive numbers that have a sum of 399?
The sum of these numbers is indeed 131 + 133 + 135 = 399. Therefore, the three consecutive odd numbers are 131, 133, and 135.
What are consecutive numbers ?
Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.
Here we will use algebra to find three consecutive integers whose sum is 399. We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 399. Therefore, you can write the equation as follows:
(X) + (X + 1) + (X + 2) = 399
To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 399
3X + 3 = 399
3X + 3 - 3 = 399 - 3
3X = 396
3X/3 = 396/3
X = 132
Which means that the first number is 132, the second number is 132 + 1 and the third number is 132 + 2. Therefore, three consecutive integers that add up to 399 are 132, 133, and 134.
132 + 133 + 134 = 399
Since, 132 + 133 + 134 equals 399 as displayed above.
Hence ,The sum of these numbers is indeed 131 + 133 + 135 = 399. Therefore, the three consecutive odd numbers are 131, 133, and 135.

b = ____ ( look at photo )
Answer:
b = 64°
Step-by-step explanation:
The sum of interior angles of a polygon is 180°(n - 2), where "n" is number of sides.
~~~~~~~~~~
180°(6 - 2) = 720°
114° + (b + 49°) + (2b - 25°) + 142° + (b + 39°) + (3b - 47°) = 720°
7b + (114° + 49° - 25° + 142° + 39° - 47°) = 720°
7b + 272° = 720°
7b = 448°
b = 64°
if the wind speed at 60 meters is 8 m/s, what is the wind speed at 80 meters? use the industry standard of 1/7 for the shear exponent. (round two decimal places)
Thus, the wind speed at 80 meters is approximately 8.74 m/s when the wind speed at 60 meters is 8 m/s and the shear exponent is 1/7.
In order to find the wind speed at 80 meters, we need to use the shear exponent. The industry standard for the shear exponent is 1/7, which means that the wind speed will decrease by a factor of 1/7 for every meter increase in height.
To calculate the wind speed at 80 meters, we can use the following formula:
Wind speed at 80m = Wind speed at 60m * (80/60)^(1/7)
Plugging in the given values, we get:
Wind speed at 80m = 8 * (80/60)^(1/7)
Wind speed at 80m = 8 * 1.092
Wind speed at 80m = 8.74 m/s
Therefore, the wind speed at 80 meters is approximately 8.74 m/s when the wind speed at 60 meters is 8 m/s and the shear exponent is 1/7.
It's important to note that the shear exponent can vary depending on the atmospheric conditions, terrain, and other factors. So, this calculation provides an estimate based on the given standard.
