If f(3) = -4, f'(3) = 4, g(3) = 2, and g'(3) = 0, find (f + g)'(3).

Answers

Answer 1

Final answer:

The derivative of the sum of functions f and g at x = 3 is calculated by adding the derivatives of f and g at 3. Given that f'(3) = 4 and g'(3) = 0, the derivative (f + g)'(3) equals 4.

Explanation:

The student is asking about the derivative of a sum of two functions at a specific point, which is a concept covered in calculus. From the given information, we know that:

f(3) = -4, f'(3) = 4g(3) = 2, g'(3) = 0

To find (f + g)'(3), we apply the rule for the derivative of a sum of functions, which states that:

(f + g)'(x) = f'(x) + g'(x)

Therefore, (f + g)'(3) is:

(f + g)'(3) = f'(3) + g'(3)

(f + g)'(3) = 4 + 0

(f + g)'(3) = 4.

Thus, the derivative of the sum of functions f and g at x = 3 is 4.

Square OSER, ER equals (2a+b) what is the area of square OSER

Answers

Answer:

4a² + 4ab + b² units²

Step-by-step explanation:

Area of a square = Length²

ER is a length of the square

ER = (2a + b)

Area of a square = (2a + b)² = (2a + b)(2a + b) = (2a)(2a) + (2a)(b) + (2a)(b) + (b)(b) = 4a² + 4ab + b²

The area of the square OSER = [tex]4a^{2}+4ab+b^{2}[/tex] sq unit

Step-by-step explanation:

Given,

Length of each side(ER) = (2a+b) unit

To find the area of the square OSER.

Formula

The area of a square with each side a unit is [tex]a^{2}[/tex] sq unit

[tex](a+b)^{2}= a^{2} +b^{2} +2ab[/tex]

Now,

The area of the square OSER = [tex](2a+b)^{2}[/tex] sq unit

= [tex]4a^{2}+4ab+b^{2}[/tex] sq unit [ by using the formula of ([tex]a+b)^{2}[/tex]]

You have inherited land that was purchased for $30,000 in 1960. The value of the land increased by approximately 5% per year. What is the approximate value of the land in the year 2011?​

Answers

Answer:

  $361,223

Step-by-step explanation:

Each year, the value is multiplied by 1+5% = 1.05. After 51 years, it has been multiplied by that factor 51 times, so is now ...

  $30,000×1.05^51 ≈ $361,223

Final answer:

To find the approximate value of land purchased for $30,000 in 1960 with a 5% annual increase by 2011, we use the compound interest formula which results in an approximate value of $447,187.25.

Explanation:

To determine the approximate value of land in the year 2011, which was purchased for $30,000 in 1960 with an average annual increase of 5%, we will use the formula for compound interest. This situation can be treated as a compound interest problem where the initial principal is the initial land value, the rate is the annual increase, and the time is the number of years the land has appreciated.

The compound interest formula is [tex]A = P(1 + r/n)^(nt),[/tex] where A is the future value of the investment/loan, including interest, P is the principal investment amount (initial value of land), r is the annual interest rate (annual increase in value), n is the number of times that interest is compounded per year, and t is the time the money is invested or borrowed for, in years.

In this scenario, P is $30,000, r is 0.05 (5% expressed as a decimal), n is 1 since we are compounding annually, and t is 51 (2011 - 1960).

Therefore,

[tex]A = 30,000(1 + 0.05/1)^(1*51).[/tex]

Carrying out the calculation gives us the approximate value of the land in 2011.

[tex]A = 30,000(1.05)^51[/tex]
Approximate value of the land in 2011 = $447,187.25

A. (6, 3)
B. (3, -6)
C. (-6, 3)
D. (-3, 6)

Answers

C. Coordinates of D' (-6,3)

Step-by-step explanation:

When any figure is rotated 180° in the counterclockwise direction, then the coordinates of the vertices is changed into its opposite sign.

(x, y) → (-x, -y)

The coordinates of the vertices of quadrilateral ABCD is changed when it is rotated 180 degrees counterclockwise about the origin as,

A (7,-7) → A'(-7,7)

B (4,-10) → B' (-4,10)

C (1.5, -2.5) → C' (-1.5, 2.5)

D (6, -3) → D'(-6,3)

So the coordinates of D' will be (-6,3)

claire spends 1/2 of her monthly salary on food, 1/4 on rent and 1/3 on power bills, she saves rest. what fraction of her monthly salary does she have?

Answers

Claire spends 1/2+1/4+1/3 on necessities, so we find a common denominator:

1/2=6/12

1/4=3/12

1/3=4/12

Then we add of these fractions together:
6/12+3/12+4/12=13/12

It looks like Claire is over-budget with her purchases.

(I’m not really sure if that is the problem)

Maybe it’s 1/2+1/8+1/24=12/24+3/24+1/24=16/24

This simplifies to 2/3 (dividing by 8).

So if Claire spends 1/2 on food, 1/4 of what’s left on rent, and 1/3 of that on power bills, then she will have 1/3 (1-2/3) left of her monthly salary.

Answer:

1/2

Step-by-step explanation:

To multiply fractions we do keep change flip, keeping the first fraction, changeing the division into multiplication and flipping the last fraction so we don't have to go into decimals   so 1/8 divded by 1/4 becomes

1/8 * 4/1

Now we multiply the numerators together and the denominators together and then put it back in fraction form. Another option is to cross reduce, both will be shown.

Multiplying numerators and denominators

1 * 4 = 4

8 * 1 = 8

Put it into fraction form;

4/8          Now simplify

1/2

Cross Reducing

To cross reduce you can divde two numbers that are accross from each other in a fraction equation (Multiplication only) by the same number

1/8 * 4/1      The four and eight are across from each other so we can cross reduce by 4 because that is there gcf

then we have

1/2 * 1/1       now we multiply the numerators by numerators and the denominators by denominators in this case we don't have to go that far though because 1/1 is 1 and anything times one is itself, therefore the awnser is

Final answer:

The length of the rectangle with a perimeter of 60 inches and a width of 12 inches is 18 inches, calculated using the perimeter formula for rectangles and solving for the length.

Explanation:

The question asks us to find the length of a rectangle given its perimeter and width. To solve this, we use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. In this case, we have P = 60 inches and w = 12 inches.

So, substituting the given values into the formula, we get:

60 = 2l + 2(12)

First, calculate the double of the width:

2(12) = 24 inches

Now, subtract this value from the total perimeter to find the double of the length:

60 - 24 = 36 inches

Finally, divide by 2 to find the length of the rectangle:

36 / 2 = 18 inches

Therefore, option B, 18 inches, is the correct answer for the length of the rectangle.

Answers

Answer:

1) A - 42°

2) 74°

3) B - 45°

4) B - 66°

Step-by-step explanation:

1) E = D+H

87 = 45 + H

H = 42°

2) 180 - 50 - D

D = 180 - 44 - 62 = 74°

3) F = 105

H = 180-105 = 75

I + H = C + E

I + 75 = 83 + 37

I = 45°

4) D = 180 - (E + F)

D = 180 - (30 + 57) = 93°

93 = A + 27

A = 66°

Answer: In figure 1, angle H = 42°. In figure 2, angle F = 56°. In figure 3, angle I = 45° and in figure 4, angle A = 66°

Step-by-step explanation: Please refer to the attached diagram for details.

From figure 1, if angle E measures 87, then angle F would be calculated as

Angle F = 180 - 87 {Sum of angles on a straight line equals 180}

Angle F = 93

Then looking at triangle FHD, we have angles D and F as 45 and 93. Angle H = 180 - (45 + 93) {Sum of angles in a triangle equals 180}

Angle H = 180 - 138

Angle H = 42

From figure 2, if triangle ACB has two angles given as 44 and 62, then the third angle C, would be calculated as

Angle C = 180 - (44 + 62) {Sum of angles in a triangle equals 180}

Angle C = 180 - 106

Angle C = 74

Note that angle D equals angle C {Opposite angles are equal}. So if angle D measures 74, then looking at triangle FED, we have two angles already, E and D which are 50 and 74. To calculate angle F, the equation would be

f = 180 - 50 - 74

f = 56

That is, angle F = 56.

From figure 3, we have angles C and E given as 83 and 37. To calculate angle G

Angle G = 180 - (83 + 37) {Sum of angles on a straight line equals 180}

Angle G = 180 - 120

Angle G = 60

Also, to calculate angle H,

Angle H = 180 - 105 {Sum of angles on a straight line equals 180}

Angle H = 75

Looking at triangle GHI, we have identified two angles which are 60 and 75. To calculate the third angle which is angle I,

Angle I = 180 - (60 + 75) {Sum of angles in a triangle equals 180}

Angle I = 180 - 135

Angle I = 45

From figure 4, if angles B and E measure 27 and 30 respectively then the whole of that angle measures 27 + 30 which equals 57.

So looking at the biggest of all three triangles, two angles have been identified which are angles F and {B + E}

To calculate angle A

Angle A = 180 - (57 + 57) {Sum of angles in a triangle equals 180}

Angle A = 180 - 114

Angle A = 66.

Answers

Answer:

Step-by-step explanation:

Given that,

x^8/x^a=x²

Applying indices

Division rule a^m ÷ a^n = a^(m-n)

Then,

x^8/x^a=x²

x^(8-a)=x²

For this to be equal means that, the power are equals since they have the same base

Then, 8-a=2

8+2=a

So, a=10

Taking the second equation

(x^6)^b=x¹²

Using indices again

x^(6b)=x¹²

Also, for this to be equal

6b=12

Then, b=12/6

b=2

Then, b=2 and =10

We need to find b-a.

b-a=2-10=-8
