Answer:

a: -2f(x+4)

Step-by-step explanation:

Took the quiz, got 100%.

The function f(x) = ∛x is transformed to obtain g(x) = -2f(x + 4). Option A is correct.

The function f(x) = ∛x is shifted horizontally to the left by 4 units.

This means that every point on the graph of f(x) is moved 4 units to the left.

After the horizontal shift, the function is reflected vertically and stretched vertically by a factor of 2.

The reflection indicates that the graph is flipped upside down, and the stretching means that the graph is elongated vertically by a factor of 2.

By applying these transformations to the function f(x) = ∛x, we obtain the function g(x) = -2f(x + 4).

The negative sign indicates the vertical reflection, and the factor of 2 represents the vertical stretching.

The horizontal shift of 4 units is applied to the argument of the function, which is (x + 4)

*Correct Question:

Based on the similar triangles shown below, Theodore claims that ∆TUV is transformed to ∆WXY with a scale factor of 3/2. Is Theodore correct?

A. Yes, the triangles are similar with a scale factor of 3/2.

B. No, the triangles are similar with a scale factor of 2/1.

C. No, the triangles are similar with a scale factor of 2/3.

D. No, the triangles are similar with a scale factor of 4/3.

Answer:

C. No, the triangles are similar with a scale factor of 2/3.

Step-by-step explanation:

∆TUV is the original triangle. After transformation, the size reduced to give us ∆WXY. This means ∆TUV was reduced by a scale factor to give ∆WXY. The scale factor should be a fraction, suggesting, the original size of the ∆ was reduced upon transformation.

Thus, the ratio of their corresponding sides = the scale factor.

This is: [tex] \frac{8}{12} = \frac{16}{24} = \frac{12}{18} = \frac{2}{3} [/tex]

If you multiply the side length of ∆TUV by ⅔, you'd get side length of ∆WXY.

So, Theodore is wrong.

Statement: As the input power's current grows beyond 1 ampere...

Feature: Relative minimum or maximum (specifically, relative maximum)

Statement: At its most efficient, the motor uses...

Feature: x-intercept

Statement: The motor loses all efficiency when the current...

Step-by-step explanation:

The first statement describes a decreasing interval, specifically the decreasing efficiency beyond 1 ampere of input current

The second statement describes a relative maximum, specifically the maximum efficiency at an input current of 1 ampere

The third statement describes an x-intercept, specifically the efficiency hitting 0% when the input current is ≥ 3 amperes

Answer:

(a) x -intercept with the last statement (the one at the bottom)

(b) Relative maximum with the second (middle) statement.

(c) Increasing or decreasing with the first (top) statement.

See details below:

Step-by-step explanation:

(a)  The x-intercept goes with the info on what happens when the graph crosses the horizontal axis, so it goes with the third statement given:

The motor loses all efficiency when the current hits 3 amps.

(b)  Relative max: agrees with what happens at the maximum the curve shows reaching approximately 50% value in the vertical scale:

At its most efficiency the motor uses about 50% of the  input power

(c)  Increasing or decreasing interval: The function clearly increases from values of the horizontal variable starting at around 0.4, up to a value of 1, and from then onwards it decreases. So it agrees with:

As the input grows more than 1 ampere, the motor becomes less efficient.

Answer:

Parametric tests are used for interval and ratio data and Non parametric tests are used for ordinal and nominal data.

Step-by-step explanation:

Parametric tests are used for interval and ratio data and Non parametric tests are used for ordinal and nominal data.

The interval data shows data with differences or intervals.

The ratio data is the one in which statistical inferences is used and can be added ,subtracted , multiplied, or divided.

Ordinal data is one in which we measure quantitative data such as height , weight  but is in order.

Nominal data  is one in which we measure quantitative data such as hair color eye color  without order or which does not require order or sequence.

Answer:

Two integers are relatively primes if and only if their only common positive integer factor is 1.

Step-by-step explanation:

The prime number is one whose only divisor is 1 and itself.

The prime factors of a whole number are the exact prime divisors of that whole number. In other words, every composite number can be written as a multiplication of two or more prime factors.

So, two integers are relative primes if they have no prime factor in common, or, put another way, if they have no common divisor other than 1.

So, two integers are relatively primes if and only if their only common positive integer factor is 1.

Answer:

6:8 and 9:12

Step-by-step explanation:

The equivalent ratios of the given quantity of silver parts of paint to green which is 3:4 are: 6:8 and 9:12.

When compared to one another, equivalent ratios are defined as having the same values.

For example, 8/16, 4/8 and 1/2 re equivalent ratios because:

Given:

The table that shows the ratio of the number of parts silver to number of parts green as 3 parts silver to 4 parts green, then

ratio = 3:4.

This means that for 3 parts of silver paint, we would require 4 parts of green paint to give the shade of paint that is needed.

so,

6/8 = 3/4

9/12 = 3/4

Thus, 6/8 = 9/12 = 3/4, which is equivalent.

Hence, the ratios that are equivalent to 3 parts silver paint to 4 parts green paint are: 6:8 and 9:12.

Answer:

The waffle cone is $3.62.

First, say what your variables are.

w = large waffle cone

s = sugar cone

Next, create two equations given the data in the word problem.

[tex]2.06 + s = w[/tex]

[tex]s = 1.56[/tex]

Because you have what the sugar cone is valued at, replace the s in the first equation with 1.56 and solve.

[tex]2.06 + (1.56) = w[/tex]

[tex]w = 3.62[/tex]

The answer is any value that you put in for x would make the equation true. When you simplify the whole equation it looks like this: 2x - 6 = 2x - 6, therefor you could replace x with any value.

Answer: {xI x ∈ R, 19 < x < 32}

Step-by-step explanation:

This notation is:

{xI condition1, condition2, ...}

The first condition is:

From what set we take the values of x?

From the set of real numbers.

x ∈ R

The other conditions are the limitations that we have for x, in this case:

19 < x < 32

Then we can write this as:

{xI x ∈ R, 19 < x < 32}

Answer:

x = 14

Step-by-step explanation:

To solve this problem, we must remember that the addition of two angles that create a straight line should have a sum of 180 degrees.

From this information, we can create the following equation.

(7x - 1) + (6x - 1) = 180

Eliminating the parentheses and grouping like terms gives us:

(7x + 6x) + (-1 + -1) = 180

Simplifying inside the parentheses on the left side produces:

13x - 2 = 180

Next, we should add 2 to both sides to isolate the variable term:

13x = 182

Finally, we should divide by 13 to get the x by itself on the left side of the equation:

13x/13 = 182/13

x = 14

Therefore, the answer to your question is x = 14.

Answer:

A)82.02 mi

B) 18.7° SE

Step-by-step explanation:

From the image attached, we can see the angles and distance depicted as given in the question. Using parallel angles, we have been able to establish that the internal angle at egg island is 100°.

A) Thus, we can find the distance between the home port and forrest island using law of cosines which is that;

a² = b² + c² - 2bc Cos A

Thus, let the distance between the home port and forrest island be x.

So,

x² = 40² + 65² - 2(40 × 65)cos 100

x² = 1600 + 4225 - (2 × 2600 × -0.1736)

x² = 6727.72

x = √6727.72

x = 82.02 mi

B) To find the bearing from Forrest Island back to his home port, we will make use of law of sines which is that;

A/sinA = b/sinB = c/sinC

82.02/sin 100 = 40/sinθ

Cross multiply to get;

sinθ = (40 × sin 100)/82.02

sin θ = 0.4803

θ = sin^(-1) 0.4803

θ = 28.7°

From the diagram we can see that from parallel angles, 10° is part of the total angle θ.

Thus, the bearing from Forrest Island back to his home port is;

28.7 - 10 = 18.7° SE

[tex]\mathbf{ - \dfrac{3 \pi^2}{2}}[/tex]

Step-by-step explanation:

Given that:

F(x, y, z) = 5xi - 5yj - 3zk

The objective is to evaluate the [tex]\int _c F \ dr .C[/tex]

and C is given by the vector function  r(t) = (sin t, cost, t) where  0 ≤ t ≤ π

[tex]F(r(t)) = 5 \ sint \ i - 5 \ cost \ j - 3t \ k[/tex]

∴

[tex]\int_c F . \ dr = \int ^{\pi}_{0} ( 5 \ sint \ i - 5 cos t \ j - 3 t \ k ) ( cos \ t , - sin \ t , 1 ) \ dt[/tex]

[tex]=\int ^{\pi}_{0} ( 5 \ sint \ cost+ 5 cos t \ sin t - 3 t) dt[/tex]

[tex]=\int ^{\pi}_{0} ( 10 \ sint \ cost) \ dt -3 \int ^{\pi}_{0} \ dt[/tex]

[tex]= \int ^{\pi}_{0} ( 10 \ sint \ cost) \ dt - 3 [\dfrac {t^2}{2}]^{\pi}_{0} \ \ dt[/tex]

[tex]= 10 [\dfrac{sin^2 \ t}{2}]^{\pi}_{0} - \dfrac{3}{2}(\pi)^2[/tex]

By dividing 2 with 10 and integrating [tex]= 10 [\dfrac{sin^2 \ t}{2}]^{\pi}_{0}[/tex]; we have:

[tex]=5(sin^2t -sin^2 0) -\dfrac{3 \pi^2}{2}[/tex]

[tex]=5(0) -\dfrac{3 \pi^2}{2}[/tex]

[tex]= 0 - \dfrac{3 \pi^2}{2}[/tex]
