The correct answer is (option A)
How did we figure this out?
We are trying to find the greatest common factor of 6 and 10 so we need to divide 10 and 6:
→ 10/6
→ = 1.6
→ = 2
How does it equal 2?Now we are rounding the number 1.6. 6 is close to 10 so it would equal 10 = 2

find the gradient vector field of f. f(x, y) = tan(3x − 4y)
The gradient vector field of f(x, y) = tan(3x − 4y) is ∇f = (3 [tex]sec^2[/tex](3x − 4y) , −4 [tex]sec^2[/tex](3x − 4y)).
The gradient vector field of f(x, y) = tan(3x − 4y) is given by ∇f = (3 [tex]sec^2[/tex](3x − 4y) , −4 [tex]sec^2[/tex](3x − 4y))
The gradient vector field, also known as the gradient of a scalar function, is a vector-valued function that describes the direction of the steepest increase of a scalar function at a given point. It is represented by the symbol ∇ and is defined as the vector of partial derivatives of the function with respect to each variable.
To find the gradient vector field of f(x, y) = tan(3x − 4y), we take the partial derivatives with respect to x and y:
∂f/∂x = 3 [tex]sec^2[/tex](3x − 4y)
∂f/∂y = −4 [tex]sec^2[/tex](3x − 4y)
The gradient vector field is a useful tool in vector calculus and can be used to find the direction of the maximum increase of a scalar function, the direction of a vector field, the direction of a level curve, the equation of a tangent plane, and many other applications.

método descrito en la demostración del teorema del conjunto generador (sección 4.3) para producir una base de H. (Expli-que cómo seleccionar los elementos apropiados de S.)
Therefore, We can use the Gaussian elimination method to find the basis of H.
Define Gaussian elimination method.In linear and multilinear algebra, the procedure of Gauss elimination involves first solving one of the simultaneous linear equations for one variable (in terms of all the others) and then substituting this expression into the other equations to discover the answers.
Define linear equation.A linear equation is an algebraic equation in which each term has an exponent of 1, which, when plotted on a graph, always yields a straight line. One example with one variable is where ax+b = 0, where a and b are fundamental values and x is the variable.
Selecting the polynomials Pi(t) = 1 + t and P2(t) = 1 - t from the set S. These are linearly independent since they cannot be written as a linear combination of the other polynomials in the set and checking if the span of Pi(t) and P2(t) is equal to H. Then expressing the remaining
polynomials P3(t), P4(t), and Ps(t) in terms of Pi(t) and P2(t) and checking if they can be written as a linear combination of Pi(t) and P2(t) or not.
P3(t) = 4 can be written as 4 * Pi(t) - 4 * P2(t)
P4(t) = 1 + 7t can be written as Pi(t) + 7 * P2(t)
Ps(t) = 1 + 2t + 7t^2 can be written as Pi(t) + 2t * P2(t) + 7 * P2(t)^2
From this, we can see that all the polynomials in S can be written as a linear combination of Pi(t) and P2(t). So, the span of Pi(t) and P2(t) equals H. Hence, { Pi(t), P2(t) } is a basis for the subspace H.

x y= -30............ (1)
and, x + y= 4 ...................(2)
So, x + (-30/x)= 4
x² - 30 = 4x
x² -4x -30 = 0
Solving the Quadratic Equation
x= (4 ±√4² - 4(1)(-30) / 2)
x= (4 ± √136)/ 2
x= (4 ± 11.66)/2
x= (4+ 11.66)/2 or x= (4- 11.66)/2
x= 15.66/2 or x= -7.66/2
x = 7. 83 or x= -3.83
So, For y=7.83

Evelyn bought some belts online for $70. She used a coupon code to get a 10% discount. The website also applied a 5% processing fee to the price after the discount. How much did Evelyn pay, in the end? Round to the nearest cent.
Answer:
66.15
Step-by-step explanation:
70 dollars - discount + fee
discount = 10% of total = 10% of 70 = 0.1 * 70 = 7
fee = 5% of discounted price
discounted price = original - discount = 70 -7 = 63
fee = 5% of 65 = 0.05 * 65 = 3.15
70 - 7 + 3.25 = 66.15

The average rate of change of g(x)=3x^2-5x from x=4 to x=8 is 90
How to determine the average rate of changeFrom the information given, we have that;
g(x) = 3x² - 5x
To determine the rate from x = 4 to x = 8
First, substitute the value of x as 4, we get;
g(4) = 3(4)² - 5(4)
expand the bracket, we get;
g(4) = 48 - 20
Subtract the values
g(4) = 28
For g(8), we get;
g(8) = 3(8)² - 5(8)
expand the bracket
g(8) = 192 -- 40
subtract the values
g(8) = 152
The average rate is;
= 152 + 28/2

A sphere has a volume of 400cm3 find the volume of sphere N whose radius is half radius of m
Answer:
The volume of sphere N is 400cm3/8 = 50cm3
Step-by-step explanation:
The volume of a sphere is given by the formula: V = 4/3 * π * r^3
where V is the volume, π is pi (approximately 3.14), and r is the radius of the sphere.
Given that the volume of sphere M is 400cm3 and the radius of sphere N is half the radius of sphere M, we can write an equation to find the volume of sphere N:
Vm = 4/3 * π * rm^3 = 400cm3
We know that radius of sphere N is half of sphere M so
rn = rm/2
So the volume of sphere N can be found by substituting the value of radius of sphere N in the sphere volume formula:
Vn = 4/3 * π * (rm/2)^3
Vn = 4/3 * π * (rm^3)/8
Vn = (Vm)/8
So, the volume of sphere N is 1/8th of the volume of sphere M, which is 400cm3.
The volume of sphere N is 400cm3/8 = 50cm3

What is the volume of a sphere?The amount of space occupied within a sphere is referred to as its volume. Every point on the surface of the sphere is equally spaced from its centre, making it a three-dimensional round solid figure.
The fixed point and fixed distance are referred to as the sphere's centre and radius, respectively.
Given that the volume of the sphere is 904.78 in³. The radius of the sphere is calculated as,
Volume = ( 4 / 3 )πr³
r³ = ( 3 x volume ) / 4π
r³ = ( 3 x 904.78 ) / 4π
r³ = 2714.34 / 4π
r³ = 216
r = 6 in
