Where does the normal line to the parabola, given below, at the given point, intersect the parabola a second time? illustrate with a sketch. (round the answers to three decimal places.) y = 4 x - 2 x^ 2 p = (2, 0)?

Answers

Answer 1
The graph of the parabola when sketched is shown in the picture illustrated as the blue curve. If you want to find the normal line to the parabola at point (2,0), you want to find the line perpendicular to the curve at that certain point. Note that two equations are perpendicular to each other when the product of their slopes is equal to -1. With that, let's find the slope of the parabola at point (2,0). The slope can be determined by finding the first derivative of the equation and substituting the x-coordinate of the point.

y' = 4 - 4x = 4-4(2) = -4
Thus, the slope of the normal line is 1/4 (negative reciprocal of -4). Its equation would be y = 1/4 x + b. To find b (y-intercept), substitute the coordinates of point (2,0):

0 = 1/4 (2) + b
b = -0.5

Therefore, the equation of the normal line is y = 1/4 x - 0.5. This is illustrated as the orange line in the picture.

A gutter at the edge of a roof drops 2 inches for every 30 feet of length. The measure of the angle to the nearest tenth of a degree that the gutter makes with the roof is ____ degrees. (Enter only the number.)

Answers

1 foot = 12 inches,

so 1 in=1/12 ft, 

this means 2 in=2/12=0.1667 ft.

check the picture, 

let the black line segment represent 30 ft of the roof, the blue line segment represent the gutter.

let α be the angle formed by the roof and the gutter.

tan α =(opposite side)/(adjacent side)= 0,1667/30=0.00556

then, α=arctan(0.00556)=0.39 (degrees)

At a grocery store, an uncooked beef roast is on sale for $4.99/lb. At the same store, prepared roast beef is at the deli for $2.99/100g. How many times more expensive is the deli roast compared to the uncooked roast?

Answers

for us to find out how many times more expensive is the deli roast compared to the uncooked roast we need to change the units;
cost of 100g=0.221lb is $2.99
cost of 1 lb will therefore be:
1/0.221*2.99
=$13.53/lb
therefore the number of times more expensive the deli roast is compared to uncooked roast is:
[price of 1lb roasted meat]/[price of 1 lb uncooked meat]
=13.53/4.99
=2.7 times

What is the approximate measure of acute ∠A when cosA=0.1045cos⁡A=0.1045? Make sure your calculator is in degree mode. Round to the nearest degree.

Answers

Final answer:

To find the acute angle A when cosA=0.1045, use a calculator in degree mode to perform the inverse cosine operation and round the result to the nearest degree, which is approximately 84 degrees.

Explanation:

To find the measure of acute ">∠A when cosA=0.1045, we use the inverse cosine function (also known as arccos or cos-1). Make sure your calculator is in degree mode. The approximate measure of acute ∠A can be calculated as follows:

Enter the value 0.1045 into the calculator.Press the inverse cosine button (often labeled as cos-1, acos, or similar) to find the angle whose cosine is 0.1045.Round the result to the nearest degree.

Using a calculator set to degree mode, the result for cos-1(0.1045) should be approximately 84 degrees, when rounded to the nearest whole degree.

D. 60

Answer:

The correct option is D) 60°

Step-by-step explanation:

Consider the provided triangle.

From the provided figure it is given that one angle is 60° and we need to find the value of y.

As we know the sum of all interior angle in a triangle is 180°.

y°+y°+60°=180°

Now solve the above equation to find the value of y.

2y°+60°=180°

2y°=180°-60°

2y°=120°

y°=120°÷2

y°=60°

Hence, the value of y is 60°.

mary and jolene are both growing tomatoes in thier backyards to sell.jolene had 3 times as many as mary.but birds had eaten 6 before she picked them all.for the season they have a total of 54 tomotoes.how many did mary grow?

Answers

Mary grew 15 tomatoes. A simple algebraic equation was formulated and solved to determine the quantity: m + 3m - 6 = 54, where m represents the number of tomatoes grown by Mary.

Given that Jolene had 3 times as many tomatoes as Mary and birds ate 6 of Jolene's tomatoes, and together they have 54 tomatoes, we need to set up an equation to solve for the number of tomatoes Mary grew.

Let's denote the number of tomatoes Mary grew as m. Therefore, Jolene grew 3m tomatoes. Since birds ate 6 of Jolene's tomatoes, we have 3m - 6 for the number of tomatoes left with Jolene. The equation representing the total number of tomatoes then becomes m (Mary's tomatoes) + (3m - 6) (Jolene's remaining tomatoes) = 54. Simplifying this equation:

m + 3m - 6 = 54

4m - 6 = 54

4m = 60

m = 15

Therefore, Mary grew 15 tomatoes.

Answers

The system b is the same

Answer:

System 1 and System 2 are equivalent.

Step-by-step explanation:

The first and second system have the same solutions, the are equivalent systems of equations. Let's calculate solutions to demonstrate it:

System 1.

[tex]\left \{ {{4x - 5y = 2} \atop { 3x - y = 8}} \right.[/tex]

If we multiply the second equations by -5, we can eliminate one variable and find the first solution:

[tex]\left \{ {{4x - 5y = 2} \atop { -15x +5y = -40}} \right.\\-11x=-38\\x=\frac{38}{11}[/tex]

Now, we use this value to find the other solution:

[tex]3x - y = 8\\3(\frac{38}{11})-y=8\\\frac{114}{11}-8=y\\ y=\frac{114-88}{11}=\frac{26}{11}[/tex]

The solution of the first system is [tex](\frac{38}{11} ;\frac{26}{11} )[/tex]

System 2.

[tex]\left \{ {{4x - 5y = 2} \atop { 10x - 7y = 18}} \right.[/tex]

We do the same process than we did before, but this time we have to multiply by [tex]-\frac{5}{7}[/tex]:

[tex]\left \{ {{4x - 5y = 2} \atop { -\frac{50}{7}x + 5y = \frac{90}{7} }} \right.\\\frac{28x-50x}{7}=\frac{-90+14}{7}\\-22x=-76\\x=\frac{38}{11}[/tex]

Then,

[tex]4x - 5y = 2\\4(\frac{38}{11})-5y=2\\\frac{152}{11}-2=5y\\ 5y=\frac{152-22}{11}\\y=\frac{130}{5(11)}=\frac{26}{11}[/tex]

The solution of the second system is  [tex](\frac{38}{11} ;\frac{26}{11} )[/tex]

Therefore, system 1 and system 2 are equivalent.

Final answer:

To approximate solutions for the system of equations, enter them into graphing technology, look for intersection points, and match them to the provided coordinates, rounding to the nearest tenth.

Explanation:

To approximate the solution(s) to the system of equations using technology, such as a graphing calculator or graphing software, you typically enter the equations into the device or program and view their intersection points. These intersection points represent the solutions to the system of equations. To get an accurate approximation to the nearest tenth of a unit, you may zoom in on the graph to clearly see where the lines intersect or use the device's built-in features to find the intersection.

You would then compare the given coordinates to the intersection points you found graphically and select the ones that match:

(0,0)

(9.2, 1.5)

(9.6, 3.5)

(5.3, 9.8)

(3.5, 9.6)

Remember to round your values to the nearest tenth as required and to quickly check if these values make sense in the context of the original problem.

Solve the triangle. B=36 a=41 c=20

Answers

In the triangle with B = 36°, a = 41, c = 20, b ≈ 45.3, C ≈ 29.5, A ≈ 114.5.

To solve the triangle, we can use the Law of Sines and the fact that the sum of angles in a triangle is 180 degrees.

Given:

[tex]- Angle \( B = 36° \)[/tex]

[tex]- Side \( a = 41 \)[/tex]

[tex]- Side \( c = 20 \)[/tex]

First, we need to find angle [tex]\( A \)[/tex]. We can use the fact that the sum of angles in a triangle is 180 degrees:

[tex]\[ A = 180 - B - C \][/tex]

We can find angle [tex]\( C \)[/tex] using the Law of Sines:

[tex]\[ \frac{\sin C}{c} = \frac{\sin B}{b} \][/tex]

Solving for [tex]\( C \):[/tex]

[tex]\[ \sin C = \frac{c \times \sin B}{b} \][/tex]

[tex]\[ \sin C = \frac{20 \times \sin 36°}{b} \][/tex]

[tex]\[ \sin C = \frac{20 \times 0.5878}{b} \][/tex]

[tex]\[ \sin C = \frac{11.756}{b} \][/tex]

Now we can find angle [tex]\( C \)[/tex] using the inverse sine function:

[tex]\[ C = \sin^{-1}\left(\frac{11.756}{b}\right) \][/tex]

Now, we can substitute [tex]\( C \) i[/tex]nto the equation for [tex]\( A \)[/tex] and solve for [tex]\( b \):[/tex]

[tex]\[ A = 180 - B - C \][/tex]

[tex]\[ A = 180 - 36 - \sin^{-1}\left(\frac{11.756}{b}\right) \][/tex]

[tex]\[ A = 144 - \sin^{-1}\left(\frac{11.756}{b}\right) \][/tex]

Since we know all three angles of the triangle, we can find [tex]\( b \)[/tex] using the Law of Sines again:

[tex]\[ \frac{\sin A}{a} = \frac{\sin B}{b} \][/tex]

[tex]\[ \sin A = \frac{a \times \sin B}{b} \][/tex]

[tex]\[ \sin A = \frac{41 \times \sin 36}{b} \][/tex]

[tex]\[ \sin A = \frac{41 \times 0.5878}{b} \][/tex]

[tex]\[ \sin A = \frac{24.0678}{b} \][/tex]

Now, we can find [tex]\( b \)[/tex] using the inverse sine function:

[tex]\[ b = \frac{24.0678}{\sin A} \][/tex]

Finally, we'll use the given values and calculate the closest option:

[tex]\[ A \approx 144 - \sin^{-1}\left(\frac{11.756}{b}\right) \][/tex]

[tex]\[ b \approx \frac{24.0678}{\sin A} \][/tex]

[tex]\[ c \approx 20 \][/tex]

B = 36°

[tex]\[ a = 41 \][/tex]

After the calculation, the closest option is:

[tex]\[ b \approx 45.3, \ C \approx 29.5, \ A \approx 114.5 \][/tex]

Complete Question:

Solve the triangle.

B = 36°, a = 41, c = 20

choices:

b ≈ 27.5, C ≈ 115.5, A ≈ 28.5

b ≈ 45.3, C ≈ 25.5, A ≈ 118.5
