The value of y in the table would be greater than the value on the graph, when x = 11 by: B. 110.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

For the table, an equation which represent its data points is given by:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 270 = (360 - 270)/(4 - 3)(x - 3)

y = 90(x - 3) + 270

y = 90x - 270 + 270

y = 90x.

When x = 11, the value of y is given by:

y = 90(11)

y = 990.

For the graph, an equation which represent its data points is given by:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 160 = (320 - 160)/(4 - 2)(x - 2)

y = 80(x - 2) + 160

y = 80x - 160 + 160

y = 80x.

When x = 11, the value of y is given by:

y = 80(11)

From the following set of points, 26 is a trapezoid but not a isosceles trapezoid while 27 is not a trapezoid at all.

A closed, four-sided trapezoid in two dimensions has a perimeter and an area. Two of the sides are considered the bases of the trapezoid because they are parallel to one another.

The non-parallel sides of a trapezoid are referred to as its legs or lateral sides. The altitude is that distance between two parallel sides that is shortest. The area of a trapezoid can be easily calculated because the opposite sides are parallel to one another.

If the given points make an isosceles trapezoid then AB and CD must be equal and BC and AD must not be equal

Lets solve

26. AB =  [tex]\sqrt{(-4-(-4))^2+(-1-6)^2}[/tex]  = 7

CD =  [tex]\sqrt{(2-(2))^2+ (6-(-4))^2}[/tex] = 10

BC = [tex]\sqrt{(-4-2)^2+ (6-6)^2}[/tex] = 6

AD = [tex]\sqrt{(-4-2)^2+ (-1-(-4))^2}[/tex] = 3√5

Thus, this not an isosceles trapezoid.

Step-by-step explanation:

The first problem sets up a situation with a right triangle. See image. Two sides are given, so you can use Pythagorean Theorem to find the last side. See image.

The second problem also sets up a right triangle. But here only one side length is given and one angle, so you use trigonometry. Sine is the ratio of the opposite side/hypotenuse. Use sine to find the missing length. See image.

I rounded these answers to the nearest hundredth (two decimal places) Check directions if they should be rounded more or less.

The Pythagorean theorem states that the square of a right-angled triangle's hypotenuse is equal to the sum of the squares of its other two sides.

You can demonstrate the congruence of two right triangles using the Hypotenuse-Leg (HL) Triangle Congruence Theorem, which is a particular instance. A right triangle is congruent with another right triangle if its hypotenuse and one of its legs are congruent with its hypotenuse and one of its legs.

The hypotenuse (longest side) square in a right-angled triangle is equal to the sum of the squares of the other two sides, according to the Pythagorean theorem (base and perpendicular).

The right triangles are said to be congruent if their respective hypotenuses and legs are congruent with one another, according to the hypotenuse-leg (HL) theorem. By the HL theorem, these triangles are congruent.

The equation of this parallel line using point slope is  y = 4x - 31.

The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis may be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables.

Given that the equation of a line is y = 4x - 2.

Here, we observe that the slope m = 4

Parallel lines have the same slope. So, the slope of the new line is:

m = 4

Given that points (x1, y1) = (5, -11) are also in the new parallel line.

Using the Point-Slope form we can write:

y - y1 = m (x - x1)

Substitute the value of x and y coordinates in the above equation:

y - (-11) = 4 (x - 5)

y + 11 = 4x - 20

y = 4x - 20 -11

y = 4x - 31

The probability that Jay fails the final exam and passed the remedial exam is P(fail the final and passed the remedial) = 0.32.

What is probability?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given:

After giving the final exam, the professor found that many of his students failed the test, so he decided to give a remedial exam.

The probability that a student passes the final exam is 0.6. Given that a student fails the final exam, the probability that the student passes the remedial exam is 0.8.

We are given the following probabilities:

P(passes the final exam) = 0.6

P(fail the final exam = (1 - 0.6) = 0.4

P(passes through the remedial | failed the final) = 0.8

We have to find P(fail the final and passed the remedial).

P(fail the final and passed the remedial) = P(passes the remedial | failed the final)*P(failed the final)

P(fail the final and passed the remedial) = 0.8 x 0.4

P(fail the final and passed the remedial) = 0.32

Hence, the probability that Jay fails the final exam and passed the remedial exam is P(fail the final and passed the remedial) = 0.32.

The resulting quadratic equation is x^2 - x - 7 = 0.

The x-values for which f(x) < 1 can be determined by solving the inequality f(x) < 1.

Since f(x) is not given in the question, we must first define it. Let's assume f(x) = x^2 - 2x + 1.

The resulting equation is (x - 1)^2 < 0.

The function f(x) is defined as f(x) = x^2 - x - 6.

From here, the equation can be solved for x using the quadratic formula, which gives us x = [7 + sqrt(73)]/2 and x = [7 - sqrt(73)]/2.

The velocity is the first derivative of the position function. The position function is given in the attached picture.

s'(t) = v(t)

The position at time t is therefore equal to the definite integral from t = 0 to time t.

Since the graph is linear, the evaluation of each definite integral is equal to the area of triangles underneath the lines.

∫₀⁴ v(t) dt = (1/2) x 2 x 6 = 6

∫₄⁷  v(t) dt = (1/2) x 1 x 8 - (1/2) x 2 x 4  = 0.

∫₇⁹  v(t) dt = 2 x (-4) = -8

The position at t = 0 is s(0) = 2

Hence,

s(4) = s(0) + ∫₀⁴ v(t) dt  = 2 + 6 = 8

s(7) = s(0) +  ∫₀⁴ v(t) dt + ∫₄⁷  v(t) dt = 2 + 6 + 0 = 8
