Answer:
see explanation
Step-by-step explanation:
Using the identities
tan x = \(\frac{sinx}{cosx}\) , cot x = \(\frac{cosx}{sinx}\) , cosec x = \(\frac{1}{sinx}\) , sec x = \(\frac{1}{cosx}\)
Consider the left side
tanθ + cotθ
= \(\frac{sin0}{cos0}\) + \(\frac{cos0}{sin0}\)
= \(\frac{sin^20+cos^20}{sin0cos0}\)
= \(\frac{1}{sin0cos0}\)
= \(\frac{1}{sin0}\) × \(\frac{1}{cos0}\)
= cosecθ × secθ
= right side , thus verified

Which equations have infinitely many solutions?
Answer:
The 1st, 3rd and 4th
Step-by-step explanation:
Answer:
Options B and D
Step-by-step explanation:
Let's solve each equation:
x-3x=-2x+4
-2x=-2x+4
0=4
No solutions, so A is wrong
x-1/3(3x)=0
x-(3x/3)=0
x-x=0
0=0
Infinitely many solutions, so B is correct
1/3x-3=4+2x
1/3x=7+2x
-5/3x=7
x=-21/5
One solution, so C is incorrect
3x+2-1/3(3x)=2+2x
3x+2-(3x/3)=2+2x
3x+2-x=2+2x
2x+2=2+2x
2x=2x
0=0
Infinitely many solutions, so D is correct
x-1/3x+2=0
2/3x+2=0
2/3x=-2
x=3
One solution, so E is incorrect
As you can see, when both sides of the equations are equal to each other such as 0=0 and x=x, you'll always have infinitely many solutions. Therefore, options B and D are correct

Answer:
When -8 is x then y = -29
When -4 is x then y = -17
When 4 is x then y = 7
When 6 is x then y = 13
Step-by-step explanation:
You simply substitute the numbers on the x row for x in the equation, then you solve the problem. (3 x -8) - 5, ect.
The vectors
[-4] [ -3 ] [-4]
u =[-3], v = [ -3 ], w = [-1]
[ 5] [-11 + k] [ 7]
are linearly independent if and only if k ≠
The vectors u, v, and w are linearly independent if and only if k ≠ -8.
To understand why, let's consider the determinant of the matrix formed by these vectors:
| -4 -3 -4 |
| -3 -3 -11+k |
| 5 -11+k 7 |
If the determinant is nonzero, then the vectors are linearly independent. Simplifying the determinant, we get:
(-4)[(-3)(7) - (-11+k)(-11+k)] - (-3)[(-3)(7) - 5(-11+k)] + (-4)[(-3)(-11+k) - 5(-3)]
= (-4)(21 - (121 - 22k + k^2)) - (-3)(21 + 55 - 55k + 5k) + (-4)(33 - 15k)
= -4k^2 + 80k - 484
To find the values of k for which the determinant is nonzero, we set it equal to zero and solve the quadratic equation:
-4k^2 + 80k - 484 = 0
Simplifying further, we get:
k^2 - 20k + 121 = 0
Factoring this equation, we have:
(k - 11)^2 = 0
Therefore, k = 11 is the only value for which the determinant becomes zero, indicating linear dependence. For any other value of k, the determinant is nonzero, meaning the vectors u, v, and w are linearly independent. Hence, k ≠ 11.
In conclusion, the vectors u, v, and w are linearly independent if and only if k ≠ 11.

There are 370 fish in the school pond, and 296 are goldfish. What percent of the fish are goldfish? help pls
Answer:
80% of the fish in the school pond are goldfish.
Step-by-step explanation:
To find the percentage of goldfish in the pond, we need to divide the number of goldfish by the total number of fish and multiply by 100.
percent of goldfish = (number of goldfish / total number of fish) x 100%
So, in this case:
percent of goldfish = (296 / 370) x 100%
percent of goldfish = 0.8 x 100%
percent of goldfish = 80%

The arrangements of numbers, variables, symbols, or phrases in a rectangular table with varying numbers of rows and columns are known as matrices, which is the plural version of the word matrix. They are rectangular arrays with defined operations for addition, multiplication, and transposition. The constituents of the matrix are its numbers or entries. Vertical entries in matrices are referred to as columns, whereas horizontal entries are known as rows. A matrix is a rectangular array of numbers, variables, symbols, or expressions that are defined for operations like subtraction, addition, and multiplication. The number of rows and columns in a matrix determines its size, sometimes referred to as its order.

if 60 of a number is 90 what is the number% of a number is 180 what is 150% of the number of beads. Hurry, it's for a test
Answer:
If 60% of a number is 90.
Suppose that the number is N.
60% of that number can be written as:
(60%/|00%)*N = 0.6*N = 90
Now we can solve that for N
0.6*N = 90
N = 90/0.6 = 150.
for the second part, we have that:
% of a number is 180, what is the 150%?
We do not have the first percentage, so i could not really answer this, so lets do it in a general way.
A% of a number N, is equal to 180.
(A%/100%)*N = 180
(A/100)*N = 180
Then:
N = 180*(100/A).
Now we want to compute the 150% of this number, this will be:
(150%/100%)*N
0.15*N = 0.15*180*(100/A). = 0.15*18,000/A = 2,700/A
Where A will depend on the first percentage.
In space, how many planes can be perpendicular to a given line at a given point on that line in space?
A. 1
B.0
C. 3
D. infinitely many
In space, there can be infinitely many planes that are perpendicular to a given line at a given point on that line.
The correct answer is Option D.
The key concept here is that a plane is defined by having at least three non-collinear points.
When a line is given, we can choose any two points on that line, and then construct a plane that contains both the line and those two points. By doing so, we ensure that the plane is perpendicular to the given line at the chosen point.
Since we can select an infinite number of points on the given line, we can construct an infinite number of planes that are perpendicular to the line at various points.
Thus, the correct answer is D. infinitely many planes can be perpendicular to a given line at a given point in space.
The correct answer is Option D.

Calculate the weight and balance and determine if the CG and the weight of the airplane are within limits.
To determine if the weight and balance of an airplane are within limits, calculations need to be performed. These calculations consider the weights of various components and their respective arm distances from the reference datum.
By comparing the calculated center of gravity (CG) with the allowable CG range, it can be determined if the CG and weight of the airplane are within limits. Weight and balance calculations are crucial for ensuring the safety and performance of an aircraft. The weight and balance system involves determining the weights of different components, such as the airframe, engines, fuel, passengers, cargo, and other equipment. Each component's weight is multiplied by its arm distance from the reference datum, which is a fixed point on the aircraft.
The arm is the horizontal distance between the reference datum and the center of gravity of a particular component. The center of gravity is the point at which the aircraft would balance if it were suspended. By summing the moments (weight multiplied by arm) of all components and dividing it by the total weight, the CG can be calculated.
To determine if the CG and weight of the airplane are within limits, the calculated CG is compared to the allowable CG range specified by the aircraft manufacturer. The allowable CG range defines the limits within which the aircraft must operate to ensure stability and controllability. If the calculated CG falls within this range, the weight and balance are considered within limits. However, if the calculated CG exceeds the allowable range, it indicates an imbalance and corrective measures, such as redistributing weight or adjusting the load, are necessary to bring the CG within acceptable limits.
In conclusion, weight and balance calculations involve determining the weights and arm distances of various components in an aircraft. By calculating the CG and comparing it to the allowable CG range, it can be determined if the weight and CG of the airplane are within limits. Ensuring proper weight distribution and CG positioning is vital for maintaining stability and controllability during flight.

On your bike, you can travel 6 miles per hour. Which variable is independent?
for the transformation rule in the form , replacing which variable with what number will result in the transformation displayed in the graph?
For the function transformation form of f(x), \(g(x) = a f(\frac{1}{b} x - h) + k \), we are replacing variable a by 2, result will in the transformation displayed in the above graph. So, option(d) is right one.
A transformation is an another way to a parent function's graph. There are serval formulas for distinct rules of transformation. If consider transformation function of f(x) is g(x) = f(x - h) + k,
Vertically transformation of function by k units. Horizontal transformation of the function f(x) by h units.g(x) = -f(x), refelction in x-axisg(x) = f(-x), reflection in y-axisg(x) = cf(x) , if c>1, vertical stretch by factor cif c < 1, vertical shrink by factor cWe have a function f(x) = 2cos(x), that is cosine function and g(x) is it's transform function. Here, \(g(x) = a f(\frac{1}{b} x - h) + k \), now see the graph carefully.
Thus, for g(x) in above graph, there are no horizontal and vertical translation. So, h = k = 0. Also, the graphs are not reflected on both axes. However, notice that the graph of g(x) is just the vertical stretched version of f(x). The values of g(x) are twice that of f(x). Therefore, the factor a must be twice, a = 2. Hence, we replace a by 2.
