Which graph corresponds to the function f(x) = x2 + 4x – 1?

Answers

Answer:

See below

Step-by-step explanation:

I don't know if this helps you, but I wanted to get you an answer as quickly as I could in case you needed it really soon.  This is what a graph of this function would look like.  Choose the answer that looks like this one.

I really hope this helps!

The graph for the given function is plotted. The graph of a function is represented by y = f(x).

How to graph a function?Consider the given function as y = f(x)Consider some values for x and find y-valuesPair these x and y values as coordinates and plot them in the graphConnect all the points forming a curve (since it is a quadratic function)

Graphing the given function:

The given function is f(x) = x² + 4x - 1

Consider x values as {-5, -4, -3, -2, -1, 0, 1, 2}

Substituting these values in the function for finding y-values

When x = -5

y = f(-5) = (-5)² + 4(-5) -1 = 4

∴ (-5, 4)

When x = -4

y = f(-4) = (-4)² + 4(-4) -1 = -1

∴ (-4, -1)

When x = -3

y = f(-3) = (-3)² + 4(-3) -1 = -4

∴ (-3, -4)

When x = -2

y = f(-2) = (-2)² + 4(-2) -1 = -5

∴ (-2, -5)

When x = -1

y = f(-1) = (-1)² + 4(-1) -1 = -4

∴ (-1, -4)

When x = 0

y = f(0) = 0 + 4(0) -1 = -1

∴ (0, -1)

When x = 1

y = f(1) = 1² + 4(1) -1 = 4

∴ (1, 4)

When x = 2

y = f(2) = 2² +4(2) -1 = 11

∴ (2, 11)

Plotting these points in the graph and connecting them gives a curve (parabola).

Checking for the vertex:

f(x) = a(x - h)² + k

⇒ x² + 4x - 1

⇒ (x - (-2))² -5

So, the vertex is (h, k) = (-2, -5).

Step-by-step explanation:

arc JL = 2 (<JKL)

arc JL = 2(82)

arc JL = 164°

The measure of JL is 164°.

The correct option is (B)

What is minor arc?

An arc whose measure is less than 180 degrees is called a minor arc.

Given: angle JKL= 82°

We know by the theorem that

"When two angles are subtended by the same arc, the angle at the centre of a circle is twice the angle at the circumference."

I was expecting a choice that said A(1,4) is in the first quadrant so 90 degrees clockwise is fourth quadrant.  For perpendicularity we reverse the coordinates, negating one of them.  For the fourth quadrant, it must be the y coordinate that's negative.  We end up at A'(4,-1).

Leticia spends $18.45 on a shirt. She spends a maximum of $3.00 more than Humberto spends. If h represents the amount
Humberto spends, which symbol can be used to complete the inequality below to represent this situation?
18.45_3+h

Answers

Answer: C

Step-by-step explanation:

Final answer:

The correct symbol to complete the inequality 18.45_3+h is ≤, representing that Leticia spends at most $3 more than Humberto, so her spending of $18.45 is less than or equal to Humberto's spending plus $3.

Explanation:

Leticia spends a certain amount on a shirt, and we have an inequality to show that she spends at most $3 more than Humberto. The inequality to represent this situation, where h represents the amount Humberto spends, is 18.45 ≤ 3 + h. This means that Leticia's spending of $18.45 is less than or equal to Humberto's spending plus an additional $3. The symbol ≤ (less than or equal to) completes the inequality because it indicates that the amount Leticia spends is not greater than the cost of the shirt plus an extra $3. In other words, Humberto's spending could be exactly $3 less than Leticia's, or even less, but not more.

Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations.
4x - 3y + z = 22
4x + y + 5z = 30
3x-y-z = 4​

Answers

The augmented matrix for this system is

[tex]\left[\begin{array}{ccc|c}4&-3&1&22\\4&1&5&30\\3&-1&-1&4\end{array}\right][/tex]

Subtract row 1 from row 2, and subtract 3(row 1) from 4(row 3):

[tex]\left[\begin{array}{ccc|c}4&-3&1&22\\0&4&4&8\\0&5&-7&-50\end{array}\right][/tex]

Multiply row 2 by 1/4:

[tex]\left[\begin{array}{ccc|c}4&-3&1&22\\0&1&1&2\\0&5&-7&-50\end{array}\right][/tex]

Subtract 5(row 2) from row 3:

[tex]\left[\begin{array}{ccc|c}4&-3&1&22\\0&1&1&2\\0&0&-12&-60\end{array}\right][/tex]

Multiply row 3 by -1/12:

[tex]\left[\begin{array}{ccc|c}4&-3&1&22\\0&1&1&2\\0&0&1&5\end{array}\right][/tex]

While this isn't exactly RREF, you can already solve the system quite easily:

[tex]\boxed{z=5}[/tex]

[tex]y+z=2\implies\boxed{y=-3}[/tex]

We can confirm this solution by continuing with the row reduction. Subtract row 3 from row 2:

[tex]\left[\begin{array}{ccc|c}4&-3&1&22\\0&1&0&-3\\0&0&1&5\end{array}\right][/tex]

Subtract -3(row 2) and row 3 from row 1:

[tex]\left[\begin{array}{ccc|c}4&0&0&8\\0&1&0&-3\\0&0&1&5\end{array}\right][/tex]

Finally, multiply row 1 by 1/4:

[tex]\left[\begin{array}{ccc|c}1&0&0&2\\0&1&0&-3\\0&0&1&5\end{array}\right][/tex]

and we end up with [tex]\boxed{(x,y,z)=(2,-3,5)}[/tex], as before.

Final answer:

To solve for x, y, and z, the given system of equations is represented as an augmented matrix, then reduced to its reduced row-echelon form through row operations, from which the solutions can be directly obtained.

Explanation:

To solve the system of equations by finding the reduced row-echelon form of the augmented matrix, we first write the system as an augmented matrix:

[ 4 -3  1 | 22 ]
[ 4  1  5 | 30 ]
[ 3 -1 -1 |  4 ]
Next, we perform row operations to convert the matrix to its reduced row-echelon form. Once we have the reduced form, we can directly read off the solutions for the variables x, y, and z.

These row operations usually involve scaling rows, adding and subtracting rows, and swapping rows to systematically bring the matrix into the desired form. The final reduced row-echelon form should look like:

[ 1 0 0 | x ]
[ 0 1 0 | y ]
[ 0 0 1 | z ]

Where x, y, and z are the solutions to the original equations. At this stage, each row corresponds to an equation of the form x=..., y=..., z=..., making it straightforward to determine the values of the variables.

Rachel works as a tutor for $15 an hour and as a waitress for $8 an hour. This month, she worked a combined total of 109 hours at her two jobs. Let t be the number of hours Rachel worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.

Answers

Answer:

$ (7t+872)

Step-by-step explanation:

Earning for 1 hour as a tutor= $15

Earnings for 1 hour as a waitress= $8

Total hours worked in the month combined jobs= 109 hrs

Number of hours worked as tutor for the month= t

Find the number of hours worked as waitress for the month= 109-t  hours

Total amount earned that month = amount earned as a tutor+ amount earned as a waitress

Amount earned as a tutor=  $15 × t = $15t

Amount earned as a waitress= $8× (109-t)= $ (872-8t)

Total amount earned combined= $ 15t + $ (872-8t)

                                                    =$ ( 15t-8t +872)

                                                    = $ (7t+872)

Final answer:

Rachel's total earnings from both jobs can be expressed as the sum of her hourly rates multiplied by the hours worked in each job, which gives the equation: Total Earnings = 15t + 8(109 - t), where t is the number of hours she worked as a tutor.

Explanation:

To write an expression for the combined total dollar amount Rachel earned this month through her two jobs, we can start by indicating that she earns $15 an hour for tutoring and $8 an hour as a waitress. Given that t represents the number of hours she worked as a tutor, we can calculate her earnings from tutoring as 15t. If the total number of hours worked is 109, then the remaining number of hours worked as a waitress would be 109 - t. Her earnings from working as a waitress would thus be 8(109 - t).

Adding these two amounts together gives us the expression for Rachel's total earnings:
Total Earnings = 15t + 8(109 - t)

Find the discriminant if 3x^2-10x=-2

Answers

[tex]3x^2-10x=-2\\3x^2-10x+2=0\\\\\Delta=(-10)^2-4\cdot3\cdot2=100-24=76[/tex]

Answer:

The discriminate is 76

Step-by-step explanation:

* Lets explain what is the discriminant

- In the quadratic equation ax² + bx + c = 0, the roots of the

 equation has three cases:

1- Two different real roots

2- One real root or two equal real roots

3- No real roots means imaginary roots

- All of these cases depend on the discriminate value (D)

- The discriminate D = b² – 4ac determined from the coefficients of  

  the equation ax² + bx + c = 0.

# If the value of D positive means greater than 0

∴ There are two different real roots

# If the value of D = 0

∴ There are two equal real roots means one real root

# If the value of D is negative means smaller than 0

∴ There is real roots but the roots will be imaginary roots

∴ We use the discriminant to describe the roots

* Lets solve the problem

∵ 3x² - 10x = -2

- Put it in the form of ax² + bx + c = 0

- Add 2 for both sides

∴ 3x² - 10x + 2 = 0

- Compare between this equation and the form up to find a , b , c

∵ 3x² - 10x + 2 = 0 and ax² + bx + c = 0

∴ a = 3 , b = -10 , c = 2

- Lets find the discriminate D

∵ D = b² - 4ac

∵ a = 3 , b = -10 , c = 2

∴ D = (-10)² - 4(3)(2)  

∴ D = 100 - 24 = 76

* The discriminate is 76

Alana has 12.5 cups of flour with which she is baking four loaves of raisin bread and one large pretzel. The pretzel requires 2.5 cups of flour to make. How much flour is in each loaf of raisin bread? Explain the steps to follow to get the answer.

Answers

Answer:2.5 cups of flour in each loaf of raisin bread

Step-by-step explanation:

The pretzel uses 2.5 cups of flour so the remaining flour is 10(12.5-2.5)

Since there are four loaves and 10 cups of flour left

Therefore one loaf has 10/4 or 2.5 cups of flour

Answer:

Four times the amount of flour for the raisin bread plus 2.5 cups equals 12.5 cups total. The equation is 4x + 2.5 = 12.5. First, I subtract 2.5 from both sides, and then I divide both sides by 4. Each loaf contains 2.5 cups of flour.

Which equation can be used to find t, the amount of time Amir spent hiking during the second, more difficult part of the hike? 3(2 – t) = 1.5t 3t = 1.5(2 – t) 3t + 1.5(2 – t) = 5 3(2 – t) + 1.5t = 5

Answers

Answer:

The equation that will be used to find t is:

                [tex]3(2-t)+1.5t=5[/tex]

Step-by-step explanation:

Total distance that is traveled by Amir is: 5 miles.

and the total time taken by him is: 2 hours.

On the first part of the hike, Amir averaged 3 miles per hour.

Let t denote the time he spent hiking during the second i.e. difficult part of the hike.

Hence, the time he spent in first part of hike is: 2-t

( Since, the total time was 2 hours)

Also, we know that:

[tex]Distance=Speed\times Time[/tex]

Hence, distance traveled in first part of hike is:

[tex]Distance=3\times (2-t)[/tex]

Now, the distance he will travel in second part of hike will be: 5-3(2-t)

Since the total distance traveled by him is 5 miles.

It is given that his speed decreased to 1.5 miles per hour.

Now, we know that:

[tex]Time=\dfrac{Distance}{Speed}[/tex]

Hence, time spent by him in second part of hike is:

[tex]t=\dfrac{5-3(2-t)}{1.5}\\\\i.e.\\\\1.5t=5-3(2-t)\\\\i.e.\\\\3(2-t)+1.5t=5[/tex]

Use the four-step process to find f'(x) and then find f'(1), f'(2), and f'(3).
f(x) = -x^2+6x-5
f'(x) =

Answers

Step 1: evaluate f(x+h) and f(x)

We have

[tex]f(x+h) = -(x+h)^2+6(x+h)-5 = -(x^2+2xh+h^2)+6x+6h-5[/tex]

[tex]= -x^2-2xh-h^2+6x+6h-5[/tex]

And, of course,

[tex]f(x)=-x^2+6x-5[/tex]

Step 2: evaluate f(x+h)-f(x)

[tex]f(x+h)-f(x)=-x^2-2xh-h^2+6x+6h-5-(-x^2+6x-5)=-2xh-h^2+6h[/tex]

Step 3: evaluate (f(x+h)-f(x))/h

[tex]\dfrac{f(x+h)-f(x)}{h}=-2x-h+6[/tex]

Step 4: evaluate the limit of step 3 as h->0

[tex]f'(x) = \displaystyle \lim_{h\to 0} \dfrac{f(x+h)-f(x)}{h}=-2x+6[/tex]

So, we have

[tex]f'(1) = -2\cdot 1+6 = 4,\quad f'(2) = -2\cdot 2+6 = 2,\quad f'(3) = -2\cdot 3+6 = 0[/tex]

85/18 divided by 17/18

Answers

Answer:

5

Step-by-step explanation:

85 * 18 / 18 * 17

18 cancels out.

85/17

= 5

Your answer for this question is 5

1.) When you divide 85/18 by 17/18, the first step you want to take is switch the reciprocal.

[tex]\frac{85}{18}[/tex]÷[tex]\frac{17}{18}[/tex]=

[tex]\frac{85}{18}[/tex]×[tex]\frac{18}{17}[/tex]

2.) When you switch the reciprocal, you then division sign is changed to times.

[tex]\frac{85}{18}[/tex]×[tex]\frac{18}{17}[/tex]

3.) Now you simply multiply

[tex]\frac{85}{18}[/tex]×[tex]\frac{18}{17}[/tex]=[tex]\frac{1530}{306}[/tex]

4.) Last step, you divide

[tex]\frac{1530}{306}[/tex] = 5

Hope This Helps.
