The ultimate grade for the course is determined by the average of all completed assignments. Answer is 92.

You must first add up all of your grades if your instructor or professor employs a total points system.Afterward, tally the number of points available for each of those grades.

Your class grade can be calculated by dividing your earned points by the total points available.Follow these steps if you want to accomplish it by hand:The letter grade's value is calculated by dividing it by the course's total number of credits.Do this for each class, then add them all up.

Subtract the total by the number of credits.

75% of the test score would be 76 x 0.75 = 57

80-57 = 23

They need 23 more points to get an 80

The 23 is 25% of the final exam grade so they would need to score a 23 x 4 = 92 on the final exam

The value of x in the interval 0 ≤x≤ pi is 2.083 so the graph f and g have parallel tangent lines

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation.  The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

f(x) = tan x

and, g(x) = x²

Now, f(x) = t g(x)

and, g(x) = x²

On differentiating f(x) we get

f'(x) = t g²(x) + 1

and, g(x) = 2x

Now, the parallel tangent line

f' (x) = g'(x)

t g²(x) + 1 = 2x

since the interval for x is 0 ≤x≤ pi.

So, the value of x = 2.083

Hence, the value of x is 2.083.

A right angled isosceles triangle is a triangle with two sides of equal length and one right angle. To prove that the points (-3, 3), (3, -7) and (7,9) are the vertices of a right angled isosceles triangle, we can use the distance formula and the Pythagorean theorem.

The distance formula is used to calculate the distance between two points in a coordinate plane. It is given by:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Using the distance formula, we can find that the distance between the points (-3, 3) and (3, -7) is:

d = √((3 - (-3))^2 + ((-7) - 3)^2) = √(6^2 + (-10)^2) = √(36 + 100) = √136

Similarly, we can find that the distance between the points (-3, 3) and (7, 9) is also √136 and the distance between the points (3, -7) and (7, 9) is √36.

Now, we can use the Pythagorean theorem, which states that in a right angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

The Pythagorean theorem can be written as:

c^2 = a^2 + b^2

Since d1 and d2 are equal, we can say that the triangle is isosceles.

So, using the distance formula and the Pythagorean theorem, we have proven that the points (-3, 3), (3, -7) and (7,9) are the vertices of a right angled isosceles triangle.

Answer: To find the values of k for which the line y = x + k is tangent to the circle x^2 + y^2 = 25, we need to substitute y = x + k into the equation of the circle and solve for x.

x^2 + (x + k)^2 = 25

Expanding the square, we get:

x^2 + x^2 + 2xk + k^2 = 25

2x^2 + 2xk + k^2 = 0

Now we can solve for x by using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 2, b = 2k and c = k^2

x = (-2k ± √(4k^2 - 42k^2)) / 2*2

x = (-k ± √(-3k^2)) / 4

Since the square root of a negative number is not a real number, we can see that there is no real value of x that will make the equation true. Therefore, the line y = x + k is never tangent to the circle x^2 + y^2 = 25

Answer:

Step-by-step explanation:

To find the values of k that will make the line y = x + k tangent to the circle x^2 + y^2 = 25, we need to set the equation of the line equal to the equation of the circle and solve for k.

First, we'll substitute y = x + k into the equation of the circle:

x^2 + (x + k)^2 = 25

Next, we'll expand the square on x + k:

x^2 + x^2 + 2xk + k^2 = 25

Now we'll combine like terms:

2x^2 + 2xk + k^2 = 25

We'll rearrange the equation so that x^2 is on one side

2x^2 + 2xk + k^2 - 25 = 0

Now we'll divide by 2

x^2 + xk + k^2/2 - 25/2 = 0

Now we'll complete the square

x^2 + xk + (k^2/2 - 25/2) = 0

x^2 + xk + (k^2/2 - 25/2) + (25/2) = (25/2)

(x + k/2)^2 = 25/2

Now we'll take the square root of both sides

x + k/2 = +-sqrt(25/2)

Now we'll solve for x

x = sqrt(25/2) - k/2 or x = -sqrt(25/2) - k/2

Now we'll substitute these values of x into the equation y = x + k and find the value of k.

x = sqrt(25/2) - k/2

y = x + k

y = sqrt(25/2) - k/2 + k

y = sqrt(25/2)

x = -sqrt(25/2) - k/2

y = x + k

y = -sqrt(25/2) - k/2 + k

y = -sqrt(25/2)

So the line y = x + k is tangent to the circle x^2 + y^2 = 25 when k = sqrt(25/2) or k = -sqrt(25/2)
