The probability of getting a 3 on the first roll and a 4 on the second roll when a the probability of getting a 3 on the first roll and a 4 on the second roll is 1/36.

Therefore the answer is 1/36.

The probability of rolling a 3 on the first roll and a 4 on the second roll is the product of the probabilities of rolling each number separately.

Since the number cube is fair, the probability of rolling any number on a single roll is 1/6. Therefore, the probability of rolling a 3 on the first roll and a 4 on the second roll is

(1/6) × (1/6) = 1/36.

The probability of rolling a 3 on the first roll and a 4 on the second roll is 1/36, or approximately 0.028.

This is because the probability of rolling any particular number on a 6-sided number cube is 1/6. Therefore, the probability of rolling a 3 on the first roll is 1/6, and the probability of rolling a 4 on the second roll is also 1/6. Since these events are independent (rolling a 3 on the first roll does not affect the probability of rolling a 4 on the second roll), you can multiply the probabilities of each event to find the probability of both events occurring.

Therefore, the probability of rolling a 3 on the first roll and a 4 on the second roll is (1/6) * (1/6) = 1/36. This can also be written as a decimal as 0.028.

A SSS (side-side-side) theorem is kind of Congruence rule where two triangles with three congruent sides. So, we can solve it by showing the congruency between two triangles.

Statement: Side-Side-Side (SSS) ,the congruence theorem states that two triangles are congruent if three of their sides are equal to the corresponding sides of the other triangle.

Proof: Given, AB = DE, BC = EF, AC = DF.

To prove: ΔABC ≅ ΔDEF.

We know that the three sides of both triangles are equal in size and length. With both triangles superimposed, DE is placed on AB, EF is placed on BC, and DF is placed on AC. That is, AB = DE, BC = EF, AC = DF. Therefore, we can say that ΔABC ≅ ΔDEF.

It will take 5 months for Eduardo and Peta to weigh the same.

Eduardo weighs 120 pounds and is gaining 5 pounds each month, so after 1 month he will weigh 120 + 5 = 125 pounds.

After 2 months he will weigh 125 + 5 = 130 pounds.

This pattern continues, so after n months he will weigh 120 + 5n pounds.

Peta weighs 160 pounds and is losing 3 pounds each month, so after 1 month she will weigh 160 - 3 = 157 pounds.

After 2 months she will weigh 157 - 3 = 154 pounds.

This pattern continues, so after n months she will weigh 160 - 3n pounds.

We want to find the number of months it will take for Eduardo and Peta to weigh the same, so we set the expressions for their weights equal to each other and solve for n:

120 + 5n = 160 - 3n

The first special case of the chain rule for the composition f o c states that the derivative of f(c(t)) is equal to f'(c(t))c'(t).

For case (a):

(f o c) (t) = f(c(t)) = f(e cos(t)) = e cos(t) sin(t)

Therefore, (f o c)' (t) = f'(c(t))c'(t) = [e cos(t) sin(t)]' (e cos(t))' = e sin(t) cos(t) (e cos(t))' = e cos(t) (-sin(t)) = -e cos2(t)

For case (d):

(f o c) (t) = f(c(t)) = f(t, -t) = t exp(-t)

Therefore,

(f o c)' (t) = f'(c(t))c'(t) = [t exp(-t)]' (t, -t)' = exp(-t) (t, -t)' = exp(-t) (1, -1) = t exp(-t) (-1) = -t exp(-t)

The first special case of the chain rule for the composition f o c states that the derivative of f(c(t)) is equal to the product of f'(c(t)) and c'(t). This means that the derivative of the composition of two functions, f and c, is equal to the product of the derivative of the outermost function and the derivative of the innermost function. To verify this for each case, we need to calculate the derivatives of both f and c, then substitute them into the equation for the derivative of the composition. For example, in case (a), we have (f o c) (t) = f(c(t)) = e cos(t) sin(t). Therefore, (f o c)' (t) = f'(c(t))c'(t) = e sin(t) cos(t) (e cos(t))' = -e cos2(t). Similarly, for case (d), we have (f o c) (t) = f(c(t)) = t exp(-t). Therefore, (f o c)' (t) = f'(c(t))c'(t) = exp(-t) (t, -t)' = -t exp(-t).

You must discover the point at which the total cost of each process is equal in order to identify the crossover point between processes a and b. The sum of the fixed cost and the variable cost per unit, multiplied by the number of units, is the cost of process A as a whole. The sum of the fixed cost and the variable cost per unit, multiplied by the quantity of units, is the cost of process b as a whole.

 You can make the overall cost of each process equal to one another and solve for the number of units to determine the crossover point.

  When x is the number of units, the total cost of process an is equal to $1000 + (5 * x).

Process B has a total cost of $500 plus (7.50 * x), where x is the number of units.

When we equalize  these two expressions, we obtain:

$1000 + (5 * x) = $500 + (7.50 * x)

     2.5 *x=500

We have found the missing angle x = 60° using the angle sum property.

The triangle's angle sum property states that the sum of its angles can equal 180 degrees. Since a triangle has three sides, each of its vertices has an angle. Regardless of whether a triangle is acute, obtuse, or right-angled, its interior angles always sum to 180 degrees.

The triangle's angle sum property is one of the geometry's most frequently used properties. The main application of this property is in the calculation of the unknown angles. The angle sum property is used to calculate the measure of an unknown interior angle when the values of the other two angles are known.

Here,

Given that

Let the angles be y, z and x

y = 80°

z = 40°

x = ?

Using the angle sum property

Sum of the interior angle of a triangle = 180°

x + y + z = 180°

x + 80 + 40 = 180

x + 120 = 180

x = 180 - 120

x = 60°

Thus, we have found the missing angle x = 60° using the angle sum property

By using properties for quotients we will see that:

We need to remember two properties.

First, the quotient of two equal numbers is always equal to 1. So for any real number a different than zero, we can write:

a/a = 1

The second property is for the quotient of powers with the same base, we can write:

a^n/a^m = a^{n - m}

Now, notice that if we take the quotient of two numbers with the same exponent, we will get:

(a^n)/(a^n) = a^{n - n} = a^0

And that is the quotient between two equal numbers, then that is equal to 1, so:

a^0 = 1

20x = 360

x = 360/20

x = 18

Then,

which represent the exterior angles of this triangle.

As a check: 54+144+162 = 360 which confirms we have the correct values.

The smallest exterior angle is therefore 54 degrees

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

Method 2

The exterior angles 3x, 8x, and 9x have the corresponding interior angles of 180-3x, 180-8x, and 180-9x in that order.

For any triangle, the interior angles always add to 180 degrees.

angle1+angle2+angle3 = 180

(180-3x)+(180-8x)+(180-9x) = 180

540-20x = 180

-20x = 180-540

-20x = -360

x = -360/(-20)

x = 18

This then leads to 3x = 3*18 = 54 degrees as the final answer.

The equation of the line that is perpendicular to 2x – 4y = 17 and contains p(-8, -2) is y = -2x - 18.

Therefore, the answer is b) y = −2x − 18.

The slope-intercept form of a line's equation is y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To find the equation of a line that is perpendicular to another line, we can use the fact that the slopes of perpendicular lines are negative reciprocals of each other. This means that if the slope of one line is m, the slope of a line perpendicular to it is -1/m.

The equation of the line that is perpendicular to 2x – 4y = 17 and contains p(-8, -2) can be found by first finding the slope of the line 2x – 4y = 17. We can do this by rearranging the equation to the slope-intercept form:

2x – 4y = 17

-4y = -2x + 17

y = (1/2)x - (17/4)

The slope of the line 2x – 4y = 17 is (1/2). Therefore, the slope of a line perpendicular to it is -2.

To find the equation of the line that is perpendicular to 2x – 4y = 17 and contains p(-8, -2), we can use the slope-intercept form of a line's equation and plug in the slope (-2) and the coordinates of the point p(-8, -2):

Answer:

To find the inverse of a function, you need to switch the roles of the x and y variables. So the inverse of ƒ(x) = 4x² for x ≤ 0 is written as ƒ^(-1)(y) = ?.

To find the inverse function, we can solve for x in terms of y:

4x² = y

x² = y/4

x = √(y/4)

So the inverse of ƒ(x) = 4x² for x ≤ 0 is ƒ^(-1)(y) = √(y/4). Note that this inverse function is only defined for y ≤ 0, since the original function is only defined for x ≤ 0.
