By using trigonometric relations, we can see that the angle x on the right triangle is:

x = 62.96°

On the image, we can see a right triangle, and we want to find the value of x, which is the measure of an angle on the right triangle.

On the given triangle we can see that the hypotenuse measures 77 units, and the adjacent cathetus to the angle has a measure of 35.

Then we can use the trigonometric relation:

cos(x) = (adjacent cathetus)/(hypotenuse)

Replacing the values that we know:

cos(x) = 35/77

Now we can apply the inverse cosine function in both sides:

Acos(cos(x)) = Acos(35/77)

x = Acos(35/77) = 62.96°

The x-coordinate of the minimum on [-2,3] is -1. This is because the second derivative of a function is equal to 0 at the minimum or maximum of the function, so f''(c) must equal 0 at the minimum of [-2,3], which is at x=-1.

1. A minimum or maximum of a function occurs when the second derivative equals 0 (f''(c) = 0).

2. Since the interval [-2,3] is given, we can determine that the minimum of the function must occur at x=-1 since the second derivative must equal 0 at the minimum.

The x-coordinate of the minimum on the interval [-2,3] is -1. This is because the second derivative of a function is equal to 0 at the minimum or maximum of the function. Therefore, for the interval [-2,3], the second derivative of the function must equal 0 at the minimum, which is at x=-1. To determine this, we can use the fact that the second derivative is equal to 0 at the minimum or maximum of a function. This means that the minimum of the function must occur at x=-1 since the second derivative must equal 0 at the minimum. This is why the x-coordinate of the minimum on the interval [-2,3] is -1.

The exponential function y = 0.5(34)t has the form y = a*b^t, where a is the initial amount and b is the rate of decay. In this case, a = 0.5 and b = 34.

To find the rate of decay as a percent, we need to find the decimal form of b and then convert it to a percent. To find the decimal form, we need to take the square root of b = 34.

√34 = 5.83

To convert this decimal to a percent, we need to multiply it by 100.

5.83 * 100 = 583%

Therefore, the rate of decay is 583%.

Now we can use these values to evaluate the function when t = 3.

y = 0.5(34)^3

y = 0.5(363)

y = 181.5

So when t = 3, the value of y is 181.5, rounded to the nearest tenth.

Note that the initial amount a = 0.5, the rate of decay r = 583% and the function at t = 3 is 181.5.

Answer:

b. |−37| + |−28|

Step-by-step explanation:

The absolute value of a number is its distance from 0 on the number line. Since the divers are below sea level, both 37 and 28 will be negative numbers.

To find the distance between the two divers, we need to add the absolute values of their depths.

The first diver is at -37 ft and the second diver is at -28 ft, so we can calculate the distance between them as |-37| + |-28| = 37 + 28 = 65 ft

A cereal box has dimensions of 12 inches, (7)3/4 inches, and 2 inches.

A pastry box has a dimensions of (3)2/3 inches, (3)1/2 inches, and (2)1/3 inches.

To find the volume of the cereal box, we multiply the length, width, and height:

12 inches * 7 and 3/4 inches * 2 inches = 96 inches * 7.75 inches * 2 inches = 1458 cubic inches

To find the volume of the pastry box, we multiply the length, width, and height:

3 and 2/3 inches * 3 and 1/2 inches * 2 and 1/3 inches = 3.666 inches * 3.5 inches * 2.333 inches = 25.158 cubic inches

To find the difference in volume between the two boxes, we subtract the volume of the pastry box from the volume of the cereal box:

Answer:

y = -[tex]\frac{9}{7}[/tex] + [tex]\frac{8}{7}[/tex]

Step-by-step explanation:

Answer:

y = [tex]-\frac{9}{7} x +\frac{8}{7}[/tex]

Step-by-step explanation:

To turn the coordinates into y=mx+b, you first need the slope, m.

To find that you would use [tex]m = \frac{y2 - y1}{x2 - x1}[/tex],

Let (-3, 5) = (x2, y2)

and (4, -4) = (x1, y1)

[tex]m = \frac{5 - (-4)}{-3 -4}[/tex]

or, [tex]m = -\frac{9}{7}[/tex].

Now you have the slope, you will need the y-intercept, b, which you will need to use the point-slope formula (y - y2) = m(x - x2) and plug one of the points and slope into the equation (It does not matter which point you use).

So, (y - 5) = [tex]-\frac{9}{7}[/tex](x - (-3) or (y - 5) = [tex]-\frac{9}{7}[/tex](x + 3)

Then you would distribute the -9/7 to the (x + 3),

which turns into

(y - 5) = [tex]-\frac{9}{7}x[/tex] + ([tex]-\frac{9}{7}[/tex])3

y - 5 = [tex]-\frac{9}{7} x -\frac{27}{7}[/tex]

After that , add 5 from both sides,

y - 5 = [tex]-\frac{9}{7} x -\frac{27}{7}[/tex]

 + 5               +5

--------------------------------

y = [tex]-\frac{9}{7} x +\frac{8}{7}[/tex]

And that should be in y=mx+b form!

Points P and Q are 3/8 unit away from 0, and because absolute values cannot be zero, the absolute values are the same. Tim is the correct one here, and the correct argument is the second answer option.

Absolute values are numbers that are either zero or positive. They can never be negative, since it is the very definition of absolute values. If a given number is negative, then you only need to change the sign to positive so that you get the absolute value of the number. For example, the absolute value of - 0.001 is 0.001.

Points P and Q are equally 3/8 unit away from 0, but P is negative and Q is positive. The distance of both are not 3/8 unit but twice as that. Even though - 3/8 and 3/8 are not the same because of the different signs, they have the same absolute value, which is 3/8. Therefore, Tim is the correct one.

A weighted mean is similar to an average. Rather than contributing equally to the final mean, some data points contribute more "weight" than others. If all of the weights are equal, the weighted mean equals the arithmetic mean (the familiar "average").

Given numbers are  -1 and 1.

A quadratic equation has two roots.

A function can have two roots. A root of a function is a point at which the function's value is equal to zero. This means that the function crosses the x-axis, and two roots means that it crosses the x-axis twice. Depending on the type of function, these two points can be either real or complex numbers. For example, the quadratic equation x2-3x+2 has two real roots, namely x = 1 and x = 2.A quadratic polynomial may have one, two, or zero roots. Quadratic polynomials have a degree of two.

The remaining area of the square is 16(4 - π) square inches.

To find the remaining area of the square after four circles are removed from it, we first need to find the area of the square and then subtract the combined area of the four circles.

The area of a square can be found by multiplying the length of one side by itself. If the circles have a radius of 2 inches, the side length of the square would be 2 inches + 2 inches + 2 inches + 2 inches = 8 inches. Therefore, the area of the square is 8 inches * 8 inches

= 64 square inches.

The area of a circle can be found by using the formula:

A = πr^2,

where A is the area, π is a constant (approximately 3.14) and r is the radius of the circle.

So the area of each circles is

A = πr^2

= π*2^2

= 4π square inches

The combined area of the four circles is 4*4π = 16π square inches.

So the remaining area of the square would be 64 square inches - 4*4π square inches

= 64 square inches - 16π square inches

The probability that the student really knew the correct answer is 0.9375, or 93.75%.

(i) If the probability that the student knows the answer to the question is 0.75 and the probability that the student guesses is 0.25, the probability that the question is answered correctly is:

P(correct) = P(knowing the answer) * P(guessing correctly given knowing the answer) + P(guessing) * P(guessing correctly given guessing)

In this case, the probability of guessing correctly given knowing the answer is 1, since the student knows the correct answer. And the probability of guessing correctly given guessing is 0.25.

Therefore, P(correct) = 0.75 * 1 + 0.25 * 0.25 = 0.75 + 0.0625 = 0.8125

(ii) If it is answered correctly, what is the probability that the student really knew the correct answer?

This is called conditional probability and is represented as P(knowing the answer | correct). To calculate it we use Bayes' theorem,

P(knowing the answer | correct) = P(correct | knowing the answer) * P(knowing the answer) / P(correct)

In this case, P(correct | knowing the answer) = 1, P(knowing the answer) = 0.75 and P(correct) = 0.8125

Therefore, P(knowing the answer | correct) = 1 * 0.75 / 0.8125 = 0.9375

So the probability that the student really knew the correct answer is 0.9375, or 93.75%.
