Answer:

The value of y is -5

Step-by-step explanation:

we have

[tex]9x+2y=8[/tex] ------> equation A

[tex]7x+2y=4[/tex] ------> equation B

we know that

If x and y satisfy both equations, then (x,y) is the solution of the system of equations

Using a graphing tool

Remember that

The solution of the systems of equations is the intersection point both graphs

The intersection point is (2,-5)

therefore

The solution of the system of equations is the point (2,-5)

The value of y is -5

To find the value of y in the given system of equations, we can use the method of substitution.

To find the value of y in the system of equations 9x + 2y = 8 and 7x + 2y = 4, we can use the method of substitution. First, we solve one equation for one variable and substitute the expression into the other equation. In this case, we can solve the second equation for y: 7x + 2y = 4, y = (4 - 7x)/2. Now substitute this expression for y in the first equation: 9x + 2((4 - 7x)/2) = 8. Simplify and solve for x. Once we have the value of x, we can substitute it back into the second equation to find y.

Answer:

[tex]f^{-1}(x)=\dfrac{e^x}{3},\ x\in(-\infty,\infty),\ y>0[/tex]

Step-by-step explanation:

Consider the function [tex]f(x)=\ln 3x.[/tex] the domain of this function is x>0 and the range of this function is all real numbers. The inverse function has the domain all real numbers and the range y>0.

If

[tex]y=\ln 3x,[/tex]

then

[tex]3x=e^y,\\ \\x=\dfrac{e^{y}}{3}.[/tex]

Change x into y and y into x:

[tex]y=\dfrac{e^x}{3}.[/tex]

Thus, the inverse function is

[tex]f^{-1}(x)=\dfrac{e^x}{3}.[/tex]

ANSWER

[tex]{f}^{ - 1} (x) = \frac{ {e}^{x} }{3} [/tex]

EXPLANATION

The given logarithmic function is

[tex]f(x) = ln(3x) [/tex]

Let

[tex]y = ln(3x) [/tex]

Interchange x and y.

[tex]x = ln(3y) [/tex]

Solve for y.

[tex] {e}^{x} = {e}^{ ln(3y) } [/tex]

[tex] {e}^{x} = 3y[/tex]

Divide both sides by 3.

[tex] \frac{ {e}^{x} }{3} = y[/tex]

Therefore

[tex] {f}^{ - 1} (x) = \frac{ {e}^{x} }{3} [/tex]

Answer:

50 miles per hour

Step-by-step explanation:

Here,

Time=  8 hours

Distance=400 miles

The speed is calculated by dividing the distance by time.

So,

Average Speed=Distance/Time

=  400/5

=50 miles per hour

The average speed of the Amtrak train traveling from Los Angeles to San Francisco, which is a distance of 400 miles in 8 hours, is 50 miles per hour.

The subject of this question is Mathematics, specifically involving the concept of speed which is a part of physical science and physics. To find the average speed of the Amtrak train, we need to divide the total distance traveled by the time taken for the journey. The total distance from Los Angeles to San Francisco is given as 400 miles, and the time taken is 8 hours.

To calculate the average speed, use the formula:

Average Speed = Total Distance / Total Time

Substituting the given values:

Average Speed = 400 miles / 8 hours = 50 miles/hour

Therefore, the average speed of the Amtrak train is 50 miles per hour.

The experimental probability of tossing tails in the given scenario is 0.4 or 40%, which is determined by dividing the number of tails (6) by the total number of tosses (15).

The student is asking to determine the experimental probability of tossing tails when a coin was tossed 15 times and resulted in 9 heads and 6 tails. Experimental probability is calculated by dividing the number of times an event occurs by the total number of trials. In this case, the coin landed as tails 6 times out of 15 tosses.

To find the experimental probability of tossing tails, use the formula:

Experimental Probability of Tails = Number of Tails / Total Number of Tosses

So, it would be:

Experimental Probability of Tails = 6 / 15

Experimental Probability of Tails = 0.4 or 40%

Answer:

The solution set represented by the following graph is:

                {x | x∈ R, x < -2}

Step-by-step explanation:

Clearly from the figure we could see that the solution set is to the left of ' -2' and excluding the point '-2' since there is a open circle at -2.

This means that -2 is not included in the set.

Also in interval; form the set of points that belong to the solution set are:

                      (-∞,-2)

in set-builder form it is written as:

                      {x | x∈ R, x < -2}

Answer:

Option A.

Step-by-step explanation:

We need to find the solution set represented by the given graph.

From the given figure it is clear that there is an open circle around -2 and shaded region lie left side of -2.

Open circle around -2 represents that -2 is not included in the solution set.

Shaded area towards left of -2 represents that the solution must be less than -2. It means the sign of inequality is "<".

From the given graph it is clear that value of x lie in the interval (-∞,-2). So, the solution set is

[tex]\text{Solution set}=\{x|x\in R,x<2\}[/tex]

Therefore, the correct option is A.

a. Triangle: 1/2*b*h = 1/2*30*15 = 225 in²

b. Rectangle: b*h = 22*30 = 660 in²

c. Semi-circle: 1/2*πr² = 1/2*π*(d/2)² = 1/2*3.14*11² = 189.97 in²

d. Total: 225 + 660 + 189.97 = 1074.97 in²

2. Find height: 20 in

3. Find volume: 1074.97*20 = 21499.4 in³

Check the picture below.

so, the composite is really, a triangular prism on top of a rectangular prism with a semi-circle.

now, if we can just get the volume of each individual solid, then we're golden.

for the triangular prism, its volume is simply the triangular face's area times the length, in this case 20.

for the rectangular prism, is the same, the rectangular face's area times the length.

now, for the semicircle is the same, let's recall, the area of a full circle is πr², so the area of half a circle is (πr²)/2.  Notice in the picture, the semi-circle has a radius of 11.

[tex]\bf \stackrel{\textit{area of the triangle}}{\left[\cfrac{1}{2}(30)(15) \right]}(\stackrel{\textit{length}}{20})~~+~~ \stackrel{\textit{rectangle's area}}{(22\cdot 11)}(\stackrel{\textit{length}}{20})~~+ \stackrel{\textit{semi-circle's area}}{\left(\cfrac{\pi 11^2}{2} \right)}(\stackrel{\textit{length}}{20}) \\\\\\ 4500+4840+1210\pi \implies \stackrel{\pi =3.14}{13139.4}[/tex]

Answer:

About 75% of the time, the mixture of cow manure and mashed bananas IS LIKELY to produce MORE biogas than pure cow manure on THIS local farm.

Step-by-step explanation:

(don't worry I guessed and got it correct)

In his experiment, Vector can report that bananas added to cow manure results in more energy production, as indicated by larger balloon growth. However, "he should mention that other factors may also influence the results".

Since the exact data from Vector's experiment isn't provided, I would still be able to draw a generalized conclusion based on the given situation. Vector produced bio-gas from cow manure and bananas, and the growth of balloons served as an indication of energy production. If the balloons corresponding to the banana-mixture bottles grew larger than the manure-only ones, it would imply that adding bananas creates more energy. Increased biogas production can be observed with larger circumference balloons because more gas fills up the balloon, causing it to grow larger. Thus, the experimenting student can report in Biogas Club that using a banana-enhanced biomass recipe for cow manure can potentially increase biogas production. It is, however, crucial to note that various other factors can influence gas production, and it might be beneficial to continue research and experimentation.

We can use the quadratic equation to find the two values of x that are roots of the given equation. We must remember that most of the quadratic equations have two roots, however, we could find quadratic equations with just one root or even with no roots, at least in the real numbers.

Quadratic equation:

[tex]\frac{-b+-\sqrt{b^{2}-4ac} }{2a}[/tex]

So,

From the given equation we have:

[tex]a=1\\b=3\\c=-5[/tex]

Substituting it into the quadratic equation to find the roots, we have:

[tex]\frac{-b+-\sqrt{b^{2}-4ac} }{2a}=\frac{-3+-\sqrt{3^{2}-4*1*-5} }{2*1}\\\\\frac{-3+-\sqrt{3^{2}-4*1*-5} }{2*1}=\frac{-3+-\sqrt{9+20} }{2}\\\\\frac{-3+-\sqrt{29}}{2}[/tex]

So,

[tex]x_{1}=\frac{-3-\sqrt{29}}{2}\\\\x_{2}=\frac{-3+\sqrt{29}}{2}[/tex]

So x 2x are the sides using Pythagorean theorem x^2 + (2x)^2= 5x^2

So the side is the square root of 5x^2 so now we have the third side

The sum of the sides should add to 28 so:

X+2x+√5x=28 factor the x

X(3+√5)=28 and we know √5=2.236

So x= 28/5.236= 5.347

To find the lengths of all three sides of the right triangle, set up two equations using the given information and the Pythagorean theorem. Solve these equations to find the values of x and the lengths of the other two sides.

Let x be the length of the shorter side of the right triangle. According to the problem, the longer side is twice as long as the shorter side, so its length is 2x. The perimeter of the triangle is given as 28, so we can set up the equation x + 2x + hypotenuse = 28. Using the Pythagorean theorem, we know that the sum of the squares of the two legs is equal to the square of the hypotenuse, so we can write another equation x^2 + (2x)^2 = hypotenuse^2. Solving these two equations will give us the lengths of all three sides of the triangle.

From the perimeter equation, we have x + 2x + hypotenuse = 28. Simplifying, we get 3x + hypotenuse = 28. Rearranging, we get hypotenuse = 28 - 3x.

Substituting this into the Pythagorean theorem equation, we have x^2 + (2x)^2 = (28 - 3x)^2. Simplifying and solving this equation will give us the value of x, which we can then use to find the lengths of the other two sides of the triangle.
