Answer: each base angle in an isosceles right triangle measures 45 degrees.

Step-by-step explanation:

In an isosceles right triangle, two sides have equal lengths, and one angle is a right angle (90 degrees).

Since it is an isosceles triangle, the two base angles (the angles opposite the equal sides) must be congruent, meaning they have the same measure.

To find the measure of each base angle, we can use the fact that the sum of the angles in a triangle is 180 degrees.

Let's denote the measure of each base angle as "x". Then, the sum of the three angles in the triangle can be expressed as:

x + x + 90 = 180

Simplifying the equation:

2x + 90 = 180

Subtracting 90 from both sides:

2x = 90

Dividing both sides by 2:

x = 45

Answer:

Arc EF = 11.30

Step-by-step explanation:

For Circle A

S = r∅

18.08=(8)∅

Where ∅ is the angle subtended by the Arc

So

∅ = 18.08/8

∅ = 2.26 (in radians)

Now

For Circle C

S = r∅

S = (5)(2.26)

S = 11.30

Polynomial M is 2(x - \((\frac{1}{12}a)^{2}\) - (1/72)\(a^{2}\) + by

To find the polynomial M, we need to rearrange the equation given to us. We can start by adding M to both sides of the equation to isolate the constant term. This gives us:

2\(x^{2}\) - (1/3)ax + by = M

Now, we have the polynomial M in terms of x, a, b, and y. However, this is not in its simplest form yet. We can simplify this further by factoring out the coefficient of x. This gives us:

2(\(x^{2}\) - (1/6)ax) + by = M

Now, we can complete the square inside the brackets to get a perfect square trinomial. This means taking half of the coefficient of x, squaring it, and adding it and subtracting it inside the brackets. This gives us:

2((x - \((\frac{1}{12}a)^{2}\)  - (1/144)\(a^{2}\)) + by = M

Simplifying this further, we get:

2(x - \((\frac{1}{12}a)^{2}\)  - (1/72\(a^{2}\) + by = M

Therefore, the polynomial M is given by:

M = 2(x - \((\frac{1}{12}a)^{2}\)  - (1/72)\(a^{2}\) + by

This is the final answer for the polynomial M.

The required graph has been attached below that represents the function f(x) = 5 cos (2x).

The graph of the function f(x) = 5 cos(2x) is a periodic function that oscillates between its maximum and minimum values as x changes.

Specifically, the function is a cosine function with amplitude 5 and period π, since the coefficient of x is 2 in the argument of the cosine function.

The graph of the function f(x) = 5 cos(2x) has a maximum value of 5 when cos(2x) = 1 (i.e., at 2x = 0 + 2πk, where k is an integer), and a minimum value of -5 when cos(2x) = -1 (i.e., at 2x = π + 2πk, where k is an integer).

Thus, the graph has been attached below that represents the given function.

Answer:

The area of the shaded region is 3.

Step-by-step explanation:

Since point E lies halfway between AB and BC, the area of the shaded region (As) consists of two identical triangles with base equal to AB and height equal to half the measure of BC:

\(A_s=2 * A_t\)

Where At is the area of each triangle.

\(\displaystyle A_t=\frac{AB*BC/2}{2}\)

\(\displaystyle A_t=\frac{AB*BC}{4}\)

We know AB=3 and BC=2, thus:

\(\displaystyle A_t=\frac{3*2}{4}=\frac{6}{4}\)

Simplifying:

\(\displaystyle A_t=\frac{3}{2}\)

Finally:

\(\displaystyle A_s=2 * \frac{3}{2}\)

\(A_s=3\)

The area of the shaded region is 3.

Note the area of the shaded region is half the area of the rectangle.

Answer:

0.1875 = 18.75% probability that a battery will last 15 hours or more given that it has lasted 10 hours or more.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

\(P(B|A) = \frac{P(A \cap B)}{P(A)}\)

In which

P(B|A) is the probability of event B happening, given that A happened.

\(P(A \cap B)\) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Lasting 10 hours or more.

Event B: Lasting 15 hours or more.

The probability that a battery will last 10 hours or more is 80%.

This means that \(P(A) = 0.8\)

Probability of lasting 10 hours or more and 15 hours or more.

This is the probability of lasting 15 hours or more(if it has lasted 15 or more, it has lasted 10 or more).

The probability that a battery will last 15 hours or more is only 15%, which means that \(P(A \cap B) = 0.15\)

What is the probability that a battery will last 15 hours or more given that it has lasted 10 hours or more?

\(P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.15}{0.8} = 0.1875\)

0.1875 = 18.75% probability that a battery will last 15 hours or more given that it has lasted 10 hours or more.

The vertical shifts in graphs are caused by a constant added to the output (y - axis).

Vertical shifts are outside changes that affect the output (y- axis) values and shift the function up or down (vertical direction).

Horizontal shifts are inside changes that affect the input (x-) axis values and shift the function left or right

The vertical shift results from a constant added to the output (y - axis). The graph will move up if the constant added is positive OR it will move down if the constant is negative.

Thus, the vertical shifts in graphs are caused by a constant added to the output (y - axis).

The chance that a randomly chosen passenger will wait longer than 3.25 minutes is 0.35, or 35%.

Probability is a way to gauge how likely something is to happen. It is a number between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty for the event.

Since the waiting times are uniformly distributed between 0 and 5 minutes, the probability density function (PDF) is:

f(x) = 1/5

for 0 ≤ x ≤ 5

f(x) = 0, otherwise

To find the probability that a randomly selected passenger has a waiting time greater than 3.25 minutes, we need to find the area under the PDF to the right of 3.25:

P(X > 3.25) = ∫\(3.25^5\) f(x) dx

= ∫\(3.25^5\) (1/5) dx

= [x/5]\(3.25^5\)

= (5 - 3.25) / 5

= 0.35

As a result, the chance that a randomly chosen passenger will wait longer than 3.25 minutes is 0.35, or 35%.
