Answer:

Distance = 7 units

Step-by-step explanation:

We can find the distance between a set of points using the distance formula, which is

\(d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\), where

Allowing (-6, 2) to be our (x1, y1) point and (-6, 9) to be our (x2, y2) point, we can plug these in and find the distance:

\(d=\sqrt{(-6-(-6))^2+(9-2)^2}\\ d=\sqrt{(-6+6)^2+(7)^2}\\ d=\sqrt{0^2+49}\\ d=\sqrt{49}\\ d=7\)

Although taking the square root of a number gives you both a negative and positive answer since squaring both a positive and negative answer yields a positive number (e.g., 2 * 2 = 4, but -2 * -2 also = 4), we cannot have a negative distance.  Thus, the distance, d, between (-6, 2) and (-6, 9) is 7 units.

Surface area = 400 ft²

Volume = 448 ft³

length = 4 ft

width = 8 ft

height = 14 ft

The storage chest is a rectangular prism in shape

We use volume of rectangular prism formula:

Hence, the volume of the storage chest is 448ft³

Surface area of rectangular prism = 2(lw + hw + hl)

Surface area = 2(4 × 8 + 14 × 8 + 14 × 4)

Surface area = 2(32 + 112 + 56)

Surface area = 2(200)

Surface area = 400 ft²

Surface area of the chest = 400 ft²

The value of a + b is 39. In this case, a = 20 and b = 19. To find a + b, we'll add the two values together:

a + b = 20 + 19 = 39. We need to find the composite function of g(x) and f(x), which is fog(x).  fog(x) = f(g(x)) = 5(4x+3) + 4 = 20x + 19

Now, we can see that a = 20 and b = 19, so
a + b = 20 + 19 = 39
Therefore, the answer is 39.  In summary, we found the composite function of g(x) and f(x) by plugging in g(x) into f(x) and simplifying. We then identified the values of a and b from the resulting expression and added them together to find the final answer of 39.  To find the value of a + b for the composite function fog(x) where f(x) = 5x + 4 and g(x) = 4x + 3, we first need to find fog(x).
fog(x) is defined as f(g(x)). So, we will substitute g(x) into f(x):
fog(x) = f(4x + 3) = 5(4x + 3) + 4
Now, we'll distribute the 5 and simplify the expression:
fog(x) = 20x + 15 + 4
Combine the constant terms:
fog(x) = 20x + 19

Answer:

slope = $50

Step-by-step explanation:

Given the linear equation, y = mx + b:

The slope (m) is the rate of change for every x number of labor hours. What this implies is that whenever the input (x-value) or the number of labor hours increases or decreases, the value of y (total cost) will increase by the given slope value.

Slope: The painting company charges $50 for every 1 hour of labor.

The y-intercept (b) represents the flat rate or initial value. In the given problem, it states that the company charges $500 for supplies. This means that regardless of whether the company finishes working on the painting job, they will charge their customers the flat rate.

Combined, the linear equation will be:

y = 50x + 500

Options

\((A)\left(-\infty , \dfrac23\right]\\\\(B)\left(-\infty , \dfrac23\right) \\\\(C)(\frac23\right, \infty ) \\\\(D) [\frac23\right, \infty )\)

Answer:

\((C)(\frac23\right, \infty )\)

Step-by-step explanation:

Given the solution to an inequality

{x|x>2/3}

The solution set does not include \(\dfrac23\) , therefore, it must be open at the left. Recall that we use a curvy bracket ( to denote openness at the left.

Since x is greater than  \(\dfrac23\) , the solution set contains all values of larger than  \(\dfrac23\) up till infinity. Since infinity is an arbitrarily large value, we also use an open bracket at the right.

Therefore, another way to represent the solution {x|x>2/3} is:

\((\frac23\right, \infty )\)

The correct option is C.

Answer:

x = 20

y = 20√2  

Step-by-step explanation:

This is a 45 - 45 - 90° special right triangle

In a 45 - 45 - 90° triangle the legs are congruent and the hypotenuse = leg * √2

If one leg = 20 then the other leg also = 20

Thus, x = 20

If leg = 20

Then hypotenuse = 20 * √2 or 20√2

Thus, y = 20√2  

Step-by-step explanation:

2x - 3y > 9

the target as slope intercept form is

y = ax + b (or any fitting inequality sign)

so, let's transform the original inequality

2x > 3y + 9

2x - 9 > 3y

2x/3 - 3 > y

or

y < 2x/3 - 3

the slope is 2/3 (always the factor of x). the y-intercept = -3.

So the radius of the circle at that instant is 1.

Let's call the radius of the circle at that instant "r."

The formula for the area of a circle is A = pi * r^2 and the formula for the circumference of a circle is C = 2 * pi * r.

If the rate of increase in the area of the circle is numerically equal to twice the rate of increase in its circumference, we can set up the following equation:

2 * (2 * pi * r) = (pi * r^2)

Solving this equation for r, we find that the radius of the circle at that instant is r = 1.

So the radius of the circle at that instant is 1.

Answer:

Step-by-step explanation:

Let's denote the speed of each car as v, and the distance that Car A travels as d. Then we can set up two equations based on the information given:

d = v * (12/60) (since Car A reaches its destination in 12 minutes)

d + 4 = v * (18/60) (since Car B travels 4 miles farther than Car A and reaches its destination in 18 minutes)

Simplifying the equations by multiplying both sides by 60 (to convert the minutes to hours) and canceling out v, we get:

12v = 60d

18v = 60d + 240

Subtracting the first equation from the second, we get:

6v = 240

Therefore:

v = 240/6 = 40

So the cars travel at a speed of 40 miles per hour.

Step-by-step explanation:

The equation representing Jim's total payment to the gym is $290 = $50 + ($20 * m), and solving for 'm', we find that Jim has been a member of the gym for 12 months.

To solve the problem, we need to set up an equation based on the information given.

Let's denote the number of months Jim has been a member of the gym as 'm'.

Jim paid a gym membership fee of $50, which is a one-time payment. Additionally, he pays $20 per month. The total amount Jim has paid to the gym is $290.

Based on this information, we can set up the equation:

Total amount paid = Membership fee + (Monthly fee * Number of months)

$290 = $50 + ($20 * m)

To solve for 'm', we need to isolate the variable 'm' on one side of the equation.

Subtracting $50 from both sides of the equation:

$290 - $50 = $20m

$240 = $20m

Finally, to find the value of 'm', we divide both sides of the equation by $20:

$240/$20 = m

12 = m

Therefore, Jim has been a member of the gym for 12 months.

In summary, by setting up an equation and solving for 'm', we find that Jim has been a member of the gym for 12 months.

The intercepts are (0, 0), (-√5, 0), and (√5, 0). The relative maximum is at (-1, 4), and the relative minimum is at (1, -4). The point of inflection is at (0, 0). There are no asymptotes.

To analyze the function f(x) = \(x^5\) - 5x, we can find intercepts, relative extrema, points of inflection, and asymptotes.

A. Intercepts:

To find the x-intercepts, we set f(x) = 0 and solve for x:

\(x^5\) - 5x = 0

x(\(x^4\) - 5) = 0

x = 0 (x-intercept at the origin)

\(x^4\) - 5 = 0

\(x^4\) = 5

x = ±√5 (two more x-intercepts)

The y-intercept occurs when x = 0:

f(0) = 0^5 - 5(0) = 0

So the y-intercept is (0, 0).

B. Relative Extrema:

To find the critical points, we take the derivative of f(x) and set it equal to zero:

f'(x) = 5\(x^4\) - 5 = 0

5\(x^4\) = 5

\(x^4\) = 1

x = ±1

To determine whether these are relative minima or maxima, we check the second derivative:

f''(x) = 20x³

When x = -1, f''(-1) = 20(-1)³ = -20 < 0, so there is a relative maximum at (x, y) = (-1, 4).

When x = 1, f''(1) = 20(1)³ = 20 > 0, so there is a relative minimum at (x, y) = (1, -4).

C. Point of Inflection:

To find the point(s) of inflection, we set the second derivative equal to zero:

20x³ = 0

x = 0

D. Asymptotes:

The function f(x) = \(x^5\) - 5x does not have any asymptotes.

E. Graphing Utility:

Using a graphing utility, we can plot the function f(x) = \(x^5\) - 5x and verify the results obtained above.

The professor would use a hypothesis test, specifically a test for the difference in means, to determine if the difference in exam averages between the samples provides convincing evidence of a difference between the time of day or if the difference is just due to chance.

Hypothesis testing is a statistical technique used to make inferences about a population based on sample data. In this scenario, the professor wants to determine if there is a significant difference in exam averages between different times of the day.

To conduct the hypothesis test, the professor would start by stating two competing hypotheses: the null hypothesis (H₀) and the alternative hypothesis (H₁). The null hypothesis typically assumes that there is no difference between the groups or conditions being compared, while the alternative hypothesis suggests that there is a difference.

In this case, the null hypothesis could be that there is no difference in exam averages between different times of the day. The alternative hypothesis would then state that there is a significant difference in exam averages based on the time of day.

Next, the professor would collect sample data from different times of the day and calculate the exam averages for each sample. Then, a suitable statistical test, such as a t-test or ANOVA (Analysis of Variance), would be applied to compare the means of the different samples.
