What are linear equations?

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.

Each dime roll has 50 dimes, then x dime rolls are worth 50×10×x=500x cents or $5x.

Each nickel roll has 40 nickels, and then y nickel rolls are worth 40×5×y=200y cents or $2y.

A. The total value of Alysha's rolls is 500x+200y cents or $(5x+2y).

If the total value of the coins is $71 and she has 9 rolls of dimes, then x = 9 and 5×9+2y=71.

⇒45+2y=71

⇒2y=71-45

⇒2y=26

⇒y=13

Therefore, Alysha has 13 nickel rolls.

Does the absolute (global) maximam / minimam have? c) Determine where f (x) curves up and down. Also find any turning points.

Answers

we are given

[tex]f(x)=e^x sin(x)[/tex]

(a)

Firstly, we will find critical numbers

so, we will find derivative

[tex]f'(x)=e^x sin(x)+e^x cos(x)[/tex]

now, we can set it to 0

and then we can solve for x

we get

[tex]x=\frac{3\pi }{4} ,x=\frac{7\pi }{4}[/tex]

now, we can draw a number line and then locate these values

and then we can find sign of derivative on each intervals

increasing intervals:

[tex][0,\frac{3\pi}{4} )U(\frac{7\pi}{4} , 2\pi][/tex]

Decreasing interval:

[tex](\frac{3\pi}{4} ,\frac{7\pi}{4} )[/tex]

(b)

Local maxima:

It is the value of x where function changes from increasing to decreasing

so, local maxima is at

[tex]x=\frac{3\pi}{4}[/tex]

Local minima:

It is the value of x where function changes from decreasing to increasing

so, local minima is at

[tex]x=\frac{7\pi}{4}[/tex]

now, we will plug critical numbers and end values into original function

and we get

At x=0:

[tex]f(0)=e^0 sin(0)[/tex]

[tex]f(0)=0[/tex]

At [tex]x=\frac{3\pi}{4}[/tex]:

[tex]f(\frac{3\pi}{4})=e^{\frac{3\pi}{4}} sin(\frac{3\pi}{4})[/tex]

[tex]f(\frac{3\pi}{4})=7.46049[/tex]

At [tex]x=\frac{7\pi}{4}[/tex]:

[tex]f(\frac{7\pi}{4})=e^{\frac{7\pi}{4}} sin(\frac{7\pi}{4})[/tex]

[tex]f(\frac{7\pi}{4})=-172.640[/tex]

At [tex]x=2\pi [/tex]:

[tex]f(2\pi)=e^{2\pi} sin(2\pi )[/tex]

[tex]f(2\pi )=0[/tex]

Global maxima:

It is the largest value among them

so, we get

[tex]f(\frac{3\pi}{4})=7.46049[/tex]

Global minima:

It is the largest value among them

so, we get

[tex]f(\frac{7\pi}{4})=-172.640[/tex]

(c)

now, we can find second derivative

[tex]f'(x)=e^x sin(x)+e^x cos(x)[/tex]

[tex]f''(x)=\frac{d}{dx}\left(e^x\sin \left(x\right)+e^x\cos \left(x\right)\right)[/tex]

[tex]=\frac{d}{dx}\left(e^x\sin \left(x\right)\right)+\frac{d}{dx}\left(e^x\cos \left(x\right)\right)[/tex]

[tex]=e^x\sin \left(x\right)+\cos \left(x\right)e^x+e^x\cos \left(x\right)-e^x\sin \left(x\right)[/tex]

[tex]f''(x)=2e^x\cos \left(x\right)[/tex]

now, we can set it to 0

and then we can solve for x

[tex]f''(x)=2e^x\cos \left(x\right)=0[/tex]

so, we get

[tex]x=\frac{\pi}{2} ,x=\frac{3\pi}{2}[/tex]

now, we  can draw number line and locate these values

and then we can find sign of second derivative on each intervals

concave up intervals:

[tex][0,\frac{\pi}{2})U(\frac{3\pi}{2}, 2\pi][/tex]

Concave down intervals:

[tex](\frac{\pi}{2} ,\frac{3\pi}{2})[/tex]

Turning points:

All values of x for which concavity changes

so, we get turning points at

[tex]x=\frac{\pi}{2} ,x=\frac{3\pi}{2}[/tex]

fff

[tex]f(x) = e^x sin (x)[/tex]

To find increasing and decreasing intervals we take derivative

[tex]f'(x) = e^xsin(x)+e^x(cosx)= e^x(sinx+cosx)[/tex]

Now we set the derivative =0  and solve for x

[tex]e^x(sinx+cosx)=0[/tex]

sinx + cosx =0

divide whole equation by cos x

[tex]\frac{sinx}{cosx} + \frac{cosx}{cosx} =0[/tex]

tanx +1 =0

tanx = 1

[tex]x=\frac{3\pi }{4}[/tex] and  [tex]x=\frac{7\pi}{4}[/tex]

Now we pick a number between 0 to  [tex]\frac{3\pi }{4}[/tex]

Lets pick  [tex]\frac{\pi }{2}[/tex]

Plug it into the derivative

[tex]f'(x) =e^{\frac{\pi }{2}}(sin(\frac{\pi}{2})+cos(\frac{\pi }{2}))[/tex]

= 4.810 is positive

So the graph of f(x) is increasing on the interval [0, [tex]x=\frac{3\pi }{4}[/tex])

Now we pick a number between   [tex]\frac{7\pi}{4}[/tex] to 2pi

Lets pick  [tex]\frac{11\pi}{6}[/tex]

Plug it into the derivative

[tex]f'(x) =e^{\frac{11\pi}{6}}(sin(\frac{11\pi}{6})+cos(\frac{11\pi }{6}))[/tex]

= 116 is positive

So the graph of f(x) is increasing on the interval [tex](\frac{7\pi }{4}, 2\pi)[/tex]

Increasing interval is [tex](0,\frac{3\pi }{4}) U (\frac{7\pi }{4}, 2\pi)[/tex]

Decreasing interval is [tex](\frac{3\pi}{4}, \frac{7\pi}{4})[/tex]

(b)

The graph of f(x) increases and reaches a local maximum at [tex]x=\frac{3\pi}{4}[/tex]

The graph of f(x) decreases and reaches a local minimum at [tex]x=\frac{7\pi}{4}[/tex]

(c)

f(0) = 0

[tex]f(2\pi)=0[/tex]

[tex]f(\frac{3\pi }{4})=7.46[/tex]

[tex]f(\frac{7\pi}{4})=-172.64[/tex]

Courtney has $50 to spend at the county fair. She spends $10 on admission and $15 on snacks. The games at the fair cost $1.25 each. Which inequality could be used to find the maximum number of x games that Courtney can play while at the fair?

Answers

$1.25x + $10 + $15 (less than or equal to) $50

Answer:

So, with the reaming 25 dollars she can play at max 20 games.

Step-by-step explanation:

Given that

Amount Courtney has to spend = $ 50

Amount Spent on Admission = $ 10

Amount Spent on Snacks = $ 15

Price of a Game at Share = $ 1.25

Now, lets find the total amount spent by her already

Amount Spent = 50 - 10 - 15 = $ 25

Suppos x represent the number of games so, we can represent the remaining amount and in term of games that can be purchased by using it

[tex]1.25x\leq25[/tex]

the above inequality can be simplified as follows

[tex]x\leq\frac{25}{1.25}[/tex]

[tex]x\leq20[/tex]

So, with the reaming 25 dollars she can play at max 20 games.

Answers

You can solve this using long division. The answer should end up being 2.3.

Answer:

2.3

Step-by-step:

To make it easier,break it down first;35.5 also means 345/10(after the point,the number of digits is the number of 0’s behind the 1 that was used to divide a whole number.e.g;784.25=78425/100 e.t.c).You can then make the divided by 15 which also means 15/1 to multiplication by reversing it to *1/15(an example is division of 17/4 reversed to multiplied by 4/17).Note;After reversing the sign would change from division to multiplication.From there,we have an easier decimal;345/10*15/1=23/10 which is then equal to 2.3

If Raul rides his bike 3 miles for 10 minutes how many mile would he ride for 60 minutes at the same speed

Answers

60 divided by 10 =6

3x6=18

Raul would ride 18 miles.

Hope this helped :)

Final answer:

Raul would ride 18 miles for 60 minutes at the same speed.

Explanation:

To find out how many miles Raul would ride for 60 minutes at the same speed, we can set up a proportion. If Raul rides 3 miles for 10 minutes, then we can say that 3 miles is to 10 minutes as x miles is to 60 minutes. Setting up this proportion, we get: 3/10 = x/60. To solve for x, we can cross multiply and then divide both sides by 10. This gives us: x = (3/10) * 60 = 18 miles.

Error Analysis. Find and Correct ALL 3 of the errors in the proof.( 3 points)

Answers

Answer: The correct reason for [tex]\angle4\cong \angle7[/tex] is property of corresponding angles and the reason for [tex]\angle4+\angle6=180[/tex] is substitute [tex]\angle7=\angle4[/tex] and the third error is the forget the property that the sum of consecutive interior angles is 180.

Explanation:

It is given that m is parallel to n.

When  two parallel lines intersected by a transversal eight angles are produced as shown in the given figure, where m and n are parallel and l is the transversal line.

In this case corresponding angles are congruent. Example [tex]\angle1\cong \angle5[/tex],[tex]\angle2\cong \angle6[/tex] etc.

So, [tex]\angle4\cong \angle7[/tex] by the property of corresponding angles.

[tex]\angle7+\angle6=180[/tex] because these are supplementary angles.

Substitute [tex]\angle7=\angle4[/tex]

[tex]\angle4+\angle6=180[/tex]

So, the correct reason is substitution.

Hence proved [tex]\angle4+\angle6=180[/tex]

The third error is the forget the property that the sum of one side interior angles is 180. Since the alternate interior angles are congruent therefore the consecutive interior angles are supplementary angles around the sum of consecutive interior angles is 180 degree.

Final answer:

The product of (3x - 4) and (2x² + 2x - 1) is calculated by multiplying each term in the first polynomial by each term in the second and combining like terms, resulting in the final expression 6x³ - 2x² - 11x + 4.

Explanation:

The product of the polynomials (3x − 4) and (2x2 + 2x − 1) is obtained by applying the distributive property, otherwise known as FOIL (First, Outer, Inner, Last) method in this context. Each term in the first polynomial is multiplied by each term in the second polynomial and then the results are summed together. The step-by-step calculation is as follows:

Multiply the First terms: (3x) × (2x2) = 6x3.

Multiply the Outer terms: (3x) × (2x) = 6x2.

Multiply the Inner terms: (− 4) × (2x2) = − 8x2.

Multiply the Last terms: (− 4) × (− 1) = 4.

Once these calculations are done, we combine like terms:

6x3 (no like terms to combine here)

6x2 − 8x2 = -2x2

(3x) × (2x) = 6x2 (already accounted for in the previous step)

(3x) × (−1) = -3x

(− 4) × (2x) = − 8x

4 (no like terms to combine here)

So, adding all these up, we get:

6x3 − 2x2 − 3x − 8x + 4

Combining the x terms, we have:

− 3x − 8x = − 11x, so the final answer is:

6x3 − 2x2 − 11x + 4

A music store gives every 20th customer a $5 gift card. Every 50th customer gets a $10.00 gift card. Which customer will be the first to receive both types of gift cards?

Answers

100th customer is your answer

Find the first number that shows up on both answers when they are added

Add 20 each time for $5 gift card:

20, 40, 60, 80, 100

Add 50 each time for $10 gift card:

50, 100

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

As seen above, the first number that shows up on both is 100, therefore, 100 is your answer

hope this helps
