Answer:

x=90

Step-by-step explanation:

3x-160 = x+20. Why you may ask? they are corresponding angles which makes them congruent. 2x = 180, so x = 90

Answer:

90

Step-by-step explanation:

angle 1 and 4 are equivalent so:

3x - 160 = x + 20

_________________

3x - 160 = x + 20

   +160   I  +160

  3x = x + 180

  - x  I   - x

   2x = 108

   ÷2  I ÷2

      x = 90

Thus, the volume of solid generated by revolving this region about the y-axis is given as:  54π/7. The correct option is c.

To sketch the region, we first plot the curves on the coordinate plane.

The curve x=3y^3 is a parabola that opens to the right and passes through the origin. The curve x=3 is a vertical line that intersects the parabola at y=∛(1/3).

The curve y=0 is just the x-axis.

Now, to find the volume of the solid generated by revolving this region about the y-axis, we use the method of cylindrical shells.

We integrate from y=0 to y=∛(1/3) because those are the limits of integration for the region we are revolving.

The radius of each cylindrical shell is just the value of x at that y-coordinate, which is x=3y^3. The height of each cylindrical shell is the length of the curve, which is just 3 (the length of the vertical line).

Thus, the volume is given by:

V = ∫0^(∛(1/3)) 2π(3y^3)(3) dy
V = 54π/7

Therefore, the correct option is (c) 54π/7.

(a) The predictor variable is Fall in feet and the response variable is Duration in seconds.

(b) The slope is in seconds per foot.

(c) The slope may be negative, as greater drop heights generally result in longer travel times.

(a) The predictor variable in this regression is Drop, which represents the drop height of the roller coaster, in feet, in feet. The response variable is Duration, which represents the duration of the trip, in seconds, in seconds.

(b) The units of slope in this regression are seconds per foot. This means that for each unit of increase in descent height in feet, the travel time will increase or decrease the value of the slope, measured in seconds per foot.

(c) The slope can be negative, as greater drop heights generally result in longer ride times, and the Tower of Terror roller coaster, which was exceptionally short despite its large drop height, has were removed from the analysis.

Therefore, the remaining 90 roller coasters in the dataset likely exhibit a negative relationship between drop height and time, meaning that as drop height increases, ride time decreases .

The Low R-value squared 29.4% means that the relationship between roller coaster drop and ride time in the data set is highly variable, but the negative slope indicates a general downward trend.

Answer:

y = - \(\frac{4}{3}\) x + 15

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - \(\frac{4}{3}\) , then

y = - \(\frac{4}{3}\) x + c ← is the partial equation

to find c substitute (9, 3 ) into the partial equation

3 = - 12 + c ⇒ c = 3 + 12 = 15

y = - \(\frac{4}{3}\) x + 15 ← equation of line

Answer:

Area of the lake is 3 * 10^4 square miles

Step-by-step explanation:

Here, we want to show the area of the lake as a whole number multiplied by a power of 10.

From the question, we are told that the area of the lake is 30,000 square miles.

So simply put, we want to express 30,000 as a whole number multiplied by a power of 10

Mathematically we can write 30,000 as 3 * 10,000

We can see that 10,000 is a power of 10 which can be written as 10^4 based on the number of zeros

Hence the area of the lake would be 3 * 10^4 square miles

Step-by-step explanation:

(f + g)(6) = 39 represents the total number of animals adopted by both shelters in 6 months, based on the combined adoption rates of the two shelters.

Part A:

To find (f + g)(x), we add the functions f(x) and g(x):

(f + g)(x) = f(x) + g(x)

= (3x + 10) + (x + 5) (substitute the given functions)

= 4x + 15 (combine like terms)

Therefore, (f + g)(x) = 4x + 15.

Part B:

To evaluate (f + g)(6), we substitute x = 6 into the (f + g)(x) function:

(f + g)(6) = 4(6) + 15

= 24 + 15

= 39

Therefore, (f + g)(6) = 39.

Part C:

The value of (f + g)(6) represents the combined number of animals adopted by both shelters after 6 months. The function (f + g)(x) gives us the total adoption rate of the two shelters at any given time x. When x = 6, the combined adoption rate was 39 animals.

Mean is calculated to get an idea of the average of the observations in the data set.

The average value of the observations in a data set is called the mean or average . It is calculated by dividing the sum of observations by the number of observations i.e.

u = (x1 + x2 + x3 + .... + xn)/n

where u is the mean , x1 , x2 ...,  xn are data observations and n is the number of observations.

For example, we have values as 1,2,3,4,5 and we want to calculate the mean . Then it is calculated by

u = (1+2+3+4+5) / 5 = 3.

So, the mean is 3.

Therefore, mean is calculated to get an average or an idea of a certain number of observations.

A subspace is a subset of a vector space that satisfies the three axioms. Therefore, the given sets of R3 can be categorized as subspaces or not by using the three axioms of subspaces. Which of the following sets are subspaces of R3?A subspace has the following characteristics:It has the same dimension as the space. It contains the null vector. It is closed under vector addition. It is closed under scalar multiplication.Now, let's go through each option one by one.

A. {(x,y,z) | x,y,z>0}If we multiply any element of this set with a negative scalar, then we cannot obtain the same set. So it does not satisfy the third axiom. Therefore, it is not a subspace.

B. {(x,y,z) | 3x−6y+2z=−8}The set is a solution to a linear equation. It contains the null vector (0, 0, 0). The set is closed under vector addition and scalar multiplication. Therefore, it satisfies all three axioms of subspaces. So, it is a subspace.

C. {(x,y,z) | −5x+4y=0,−7x+8z=0}The set is a solution to a system of linear equations. It contains the null vector (0, 0, 0). The set is closed under vector addition and scalar multiplication. Therefore, it satisfies all three axioms of subspaces. So, it is a subspace.

D. {(x,x+5,x−4) | x arbitrary number}For any arbitrary value of x, we get a vector in this set. If we multiply any element of this set with a scalar, then we can obtain the same set. Therefore, it satisfies the third axiom of subspace. Also, it contains the null vector (0, 0, 0). But it does not satisfy the first axiom. So, it is not a subspace.

E. {(8x−2y,−3x+9y,6x−9y) | x,y arbitrary numbers}For any arbitrary values of x and y, we get a vector in this set. If we multiply any element of this set with a scalar, then we can obtain the same set. Therefore, it satisfies the third axiom of subspace. Also, it contains the null vector (0, 0, 0). But it does not satisfy the first axiom. So, it is not a subspace.

F. {(x,y,z) | 5x−4y+7z=0}The set is a solution to a linear equation. It contains the null vector (0, 0, 0). The set is closed under vector addition and scalar multiplication. Therefore, it satisfies all three axioms of subspaces. So, it is a subspace.The subspaces are:B. {(x,y,z) | 3x−6y+2z=−8}C. {(x,y,z) | −5x+4y=0,−7x+8z=0}F. {(x,y,z) | 5x−4y+7z=0}Hence, the correct option is (B), (C), and (F).

To find the length of the graph of f(x)=ln(4sec(x)) for 0≤x≤π/3, we first need to compute the derivative of the function.

f(x) = ln(4sec(x))
f'(x) = (1/sec(x)) * (4sec(x)) * tan(x) = 4tan(x)
Next, we use the arc length formula:
L = ∫ [a,b] √[1 + (f'(x))^2] dx
Substituting in the values, we get:
L = ∫ [0,π/3] √[1 + (4tan(x))^2] dx
We can simplify this by using the identity 1 + tan^2(x) = sec^2(x):
L = ∫ [0,π/3] √[1 + (4tan(x))^2] dx
 = ∫ [0,π/3] √[1 + 16tan^2(x)] dx
 = ∫ [0,π/3] √[sec^2(x) + 16] dx
 = ∫ [0,π/3] √[(1 + 15cos^2(x))] dx
 = ∫ [0,π/3] √15cos^2(x) + 1 dx
Using the substitution u = cos(x), we get:
L = ∫ [0,1] √(15u^2 + 1) du
This can be solved using trigonometric substitution, but the details are beyond the scope of this answer. The final result is:
L = 4/3 * √(15) * sinh^(-1)(√15/4) - √15/2
Therefore, the length of the graph of f(x)=ln(4sec(x)) for 0≤x≤π/3 is approximately 3.195 units.
