The anti derivative of the function eˣ² is eˣ²/2x.

The given function is;  eˣ².

To find the anti derivative of the function, integrate the function with respect to x.

Let y = eˣ²

Integration of exponential function remains same but applying the chain rule, the derivative of the power of exponent comes at the denominator.

∫y. dx = ∫eˣ² .dx.

∫eˣ² .dx. = eˣ²/(d/dx)x²

∫eˣ² .dx. =  eˣ²/2x

Thus, the anti derivative of the function is found as eˣ²/2x.

The number of pounds of peaches sold is given as follows:

65 pounds, option 2.

The amount is obtained solving a system of equations, for which the variables are given as follows:

She sold a total of 165 pounds, hence:

x + y = 165

x = 165 - y.

She made $337.50, hence:

1.75x + 2.5y = 337.50.

Replacing the first equation into the second, the value of y is obtained as follows:

1.75(165 - y) + 2.5y = 337.50

0.75y = 48.75

y = 48.75/0.75

y = 65 pounds.

Answer:

9)  17 miles/hr

10)  7.14 miles

Step-by-step explanation:

See the attached worksheet.  Note the use of conversion factors.  In question 9 we want to convert minutes to hours.  We know there are 60 minutes/hr.  So we can set up a conversion factor in one of 2 ways:  (60 minutes/1 hr) or (1 hr/60 minutes).  Both are valid, and both are = 1, since the numerator and denominator are both equivalent.  This means we can invert a conversion factor and it is still = 1.  Since conversion facots are equal to 1, we can multiply them times anything, and the result is numerically the same (anything times 1 = anything) and only the units have changed.  For question 9, we want to convert miles/min to miles/hr.  I'll choose the conversion factor (60 min/1 hr), mostly because I like multiplication over division.  Note how the units cancel in the attachment, resulting in 17 miles/hr.  One may also use the factor (1hr/60min), but then a division is required.  Perfectly fine, but not my preferred route.

The same approach is used to answer question 10.  Again, note how he units cancel, leaving a number wth just the units desired,

Answer:

Step-by-step explanation:

If E and F are complementary I means that the sum of their angles add up to 90° since all complementary angles have the sum of their angles equal to 90°

To find m\(\angle\)F add m\(\angle\)E and m\(\angle\) F and equate it to 90 to find x then substitute it into the expression for m\(\angle\)F

Thats

m\(\angle\)E + m\(\angle\)F = 90

\(\rarr\) 9x - 38 + 2x + 40 = 90

\(\rarr\) 11x + 2 = 90

\(\rarr\) 11x = 90 - 2

\(\rarr\) 11x = 88

Divide both sides by 11

x = 8

Now we have

if m \(\angle\)F = 9x - 38

m\(\angle\) F = 9( 8) - 38

m\(\angle\)F = 72 - 38

Answer:

51380000 mg

Step-by-step explanation:

10 - 3 = 7

7.34 x 7 = 51.38

1 kg = 1000000 mg

51.38 x 1000000 = 51380000

When \(7.34 \times 10^{-3} kg\) is converted to milligrams the result is 7340 mg.

Given, that kilograms to be converted to milligrams.

Multiplication: It is the basic mathematical operation among subtraction, division and addition. Multiplication follows associative and distributive property.

Exponential multiplication:

a) \(10^{-3} = \frac{1}{1000}\)

b) \(10^3 = 1000\)

Conversion factors:

1 Kg = 1000 grams

1 Gram = 100 milligrams

1 kg = 1000000 mg

Apply unitary method to convert Kg to mg.

1 kg = 1000000 mg

Multiply both sides by  \(7.34 \times 10^{-3} kg\)

\(7.34 \times 10^{-3} kg\) × 1 = \(7.34 \times 10^{-3} kg\) × 1000000

Here the kilograms is converted to equivalent milligrams.

\(7.34 \times 10^{-3} kg\) = 7340 milligrams

Thus the total milligrams in \(7.34 \times 10^{-3} kg\) are 7340 .

The vectors u, v, and w are linearly independent if and only if k ≠ -8.

To understand why, let's consider the determinant of the matrix formed by these vectors:

| -4   -3    -4   |

| -3   -3    -11+k |

| 5    -11+k  7    |

If the determinant is nonzero, then the vectors are linearly independent. Simplifying the determinant, we get:

(-4)[(-3)(7) - (-11+k)(-11+k)] - (-3)[(-3)(7) - 5(-11+k)] + (-4)[(-3)(-11+k) - 5(-3)]

= (-4)(21 - (121 - 22k + k^2)) - (-3)(21 + 55 - 55k + 5k) + (-4)(33 - 15k)

= -4k^2 + 80k - 484

To find the values of k for which the determinant is nonzero, we set it equal to zero and solve the quadratic equation:

-4k^2 + 80k - 484 = 0

Simplifying further, we get:

k^2 - 20k + 121 = 0

Factoring this equation, we have:

(k - 11)^2 = 0

Therefore, k = 11 is the only value for which the determinant becomes zero, indicating linear dependence. For any other value of k, the determinant is nonzero, meaning the vectors u, v, and w are linearly independent. Hence, k ≠ 11.

In conclusion, the vectors u, v, and w are linearly independent if and only if k ≠ 11.

It would be more appropriate to multiply the rate of 4 apples per minute by the given time of 8 minutes. This would result in 32 apples, as Dennis correctly stated, but his reasoning behind this calculation was flawed.

Dennis' reasoning is incorrect.

To determine the rate of picking apples per minute, Dennis correctly divided the total number of apples (24) by the time it took (6 minutes), resulting in 4 apples per minute. However, his approach to calculating the number of apples that could be picked in 8 minutes is flawed.

Dennis multiplied the rate of picking apples per minute (4 apples) by the given time (8 minutes), assuming that the rate remains constant. This approach would be valid if the rate of picking apples per minute were constant, but in this scenario, it is not necessarily the case.

The rate of picking apples could vary depending on factors such as fatigue, efficiency, or other variables. Therefore, it is not accurate to assume that the rate of picking apples per minute remains the same over a longer duration of time.

To determine the number of apples that could be picked in 8 minutes, it would be more appropriate to multiply the rate of 4 apples per minute by the given time of 8 minutes. This would result in 32 apples, as Dennis correctly stated, but his reasoning behind this calculation was flawed.

Answer:

c would be the closest

Step-by-step explanation:

All triangles equal 180*. so if you combine the 2 angles, which adds up to 77* then that would leave the third angle to be 103* but since that isnt an option choose c since its the closest.

Answer:

105°.

Step-by-step explanation:

1) to calculate m(∠ABC): m(∠ABC)=180-m(∠BAC)-m(∠(ACB)=180-90-65=25°;

2) note, m(∠ABC)=m∠(ABD)=25°, then it is possible

3) to calculate m(∠BAD): m(∠BAD)=180-m(∠ABD)-m(∠ADB)=180-25-50=105°.

The line segment joining the first point (-1, -5, 4) to the second point (-6, 4, -2) can be represented by parametric equations.  The parametric equations are: x = -1 + t(-5) y = -5 + t(9) z = 4 + t(-6)

To derive the parametric equations, we use the concept of parameterization. Let's introduce a parameter t that varies from 0 to 1 to represent the distance along the line segment.

We can find the direction vector of the line segment by subtracting the coordinates of the first point from the coordinates of the second point:

Direction vector = (-6, 4, -2) - (-1, -5, 4) = (-5, 9, -6)

Now, we can express the parametric equations by adding the direction vector multiplied by the parameter t to the coordinates of the first point:

x = -1 + t(-5)

y = -5 + t(9)

z = 4 + t(-6)

These parametric equations allow us to generate points along the line segment by plugging in different values of t. When t = 0, we get the first point (-1, -5, 4), and when t = 1, we get the second point (-6, 4, -2). As t varies between 0 and 1, we traverse the line segment connecting the two points.

The Jackson family averaged 22.71 miles per gallon on their trip.

To find out the average miles per gallon used by the Jackson family on their trip, the distance they covered and the amount of fuel they consumed are both necessary information.

They started their trip with an odometer reading of 18,649.3 miles, and the odometer reading at the end of the trip was 20,630.5.

The distance covered, therefore, is:20,630.5 - 18,649.3 = 1,981.2 miles

Next, to determine the average miles per gallon, divide the total distance covered by the amount of fuel consumed:1,981.2 miles ÷ 87.3 gallons

The value of the integral is (x²+1)^(3/2)/3 + C.

To evaluate the integral:

I = ∫x √(x²+1) dx

we can use substitution u = x²+1, which implies du/dx = 2x or dx = du/2x.

Substituting these values in the integral, we get:

I = ∫x √(x²+1) dx

Let u = x²+1, then

du/dx = 2x -> dx = du/2x

Substituting, we get:

I = ∫√u (du/2)

I = (1/2) ∫u^(1/2) du

I = (1/2) * (2/3) u^(3/2) + C

I = u^(3/2)/3 + C

I = (x²+1)^(3/2)/3 + C
