By applying the slope of the function at that point, linear approximation provides an estimate of the value of a function close to a beginning point.

When estimating the value of a function at a nearby location, linear approximation uses the slope of the function at a particular position. In order to arrive at the starting position, it first calculates the difference between the two points, multiplies it by the slope, and adds it. This provides a rough estimate of the function's value at the new location. A technique for calculating a function's value close to a beginning point is called linear approximation. It is predicated on the notion that a linear function can be used to roughly approximate the function close to the point of interest. This indicates that the value of the function at surrounding places can be inferred from the slope of the function at the point in question.

The total cost of the skateboard is $76.07.

The first step is to determine the price of the skateboard after the 12% discount. A discount reduces the price of an item.

Price after discount = price before discount x (1 - percent discount)

Caleb can choose which 20 items to buy in 1140 ways if he wants all 3 cheeses.

To choose 20 items at the grocery store, Caleb has narrowed down his selections to 5 vegetables, 8 fruits, 3 cheeses, and 7 whole grain breads. Since he wants all 3 cheeses, he only needs to choose 17 more items.

The number of ways he can choose these 17 items from the remaining vegetables, fruits, and breads is given by the combination: C(5+8+7, 17) = C(20, 17) = 1140.

This formula means that there are 20 items to choose from, and Caleb wants to choose 17. The order doesn't matter, so we use a combination.

Answer:

Step-by-step explanation:

To find the appropriate scale factor, we need to determine how many times smaller the piece of paper is compared to the dog. We can start by finding the ratio of the length of the paper to the length of the dog:

3 inches / 9 inches = 1/3

Similarly, the ratio of the width of the paper to the height of the dog is:

5 inches / 7 inches = 5/7

So, the smaller of these two ratios, 1/3, is the appropriate scale factor for Meredith to use in her drawing. This means that the length of the dog in the drawing will be 9 inches * 1/3 = 3 inches, and the height will be 7 inches * 1/3 = 2.3333 inches.

The measures of the angles formed by the cords and secant in the circle are found using circle theorems and presented as follows;

A secant is a line that has two points of intersection on a circle.

The specified parameters are;

1. The measure of arc  [tex]m\widehat{AB}[/tex] = 80°, and the measure of [tex]m\widehat{CD}[/tex] = 15°

Angle at the center of the circle = 2 × Angle at the circumference

Angle at the center of the circle = The arc angle of the circle

Therefore;

m∠DAC = 15°/2 = 7.5°

m∠ACO = 80°/2 = 40°

The external angle of a triangle theorem, indicates that we get;

m∠1 = 40° + 7.5° = 47.5°

m∠1 = 47.5°

2. m∠BOD = 100°, [tex]m\widehat{AC}[/tex] = 90°

The intersecting chords theorem indicates that we get;

m∠BOD = (1/2)×([tex]m\widehat{AC}[/tex] + [tex]m\widehat{BD}[/tex])

Therefore; 100° = (1/2)×(90° + [tex]m\widehat{BD}[/tex])

[tex]m\widehat{BD}[/tex] = 2 × 100° - 90° = 110°

[tex]m\widehat{BD}[/tex] = 110°

3. [tex]m\widehat{AB}[/tex] = 90°, [tex]m\widehat{CD}[/tex] = 20°

Therefore; m∠ACO = 90°/2 = 45°

m∠DAC = 20°/2 = 10°

The external angle theorem indicates that we get;

m∠COD = 45° + 10° = 55°

m∠COD = 55°

4. m∠1 = 35°, [tex]m\widehat{AB}[/tex] = 50°, therefore;

m∠ACO = 50°/2 = 25°

m∠CAO = 35° - 25° = 10°

[tex]m\widehat{CD}[/tex] = 2 × m∠CAO

Therefore; [tex]m\widehat{CD}[/tex] = 2 × 10° = 20°

[tex]m\widehat{CD}[/tex] = 20°

5. m∠AOC = (1/2)×([tex]m\widehat{AC}[/tex] + [tex]m\widehat{BD}[/tex])

Therefore; m∠AOC = (1/2)×(90° + 110°) = 100°

m∠AOC = 100°

6. [tex]m\widehat{CD}[/tex] = 20° and [tex]m\widehat{AB}[/tex] = 70°

The external secant, tangent theorem, indicates that we get;

m∠APB = (1/2) × ([tex]m\widehat{AB}[/tex] - [tex]m\widehat{CD}[/tex])

m∠APB = (1/2) × (70° - 20°) = 25°

m∠APB = 25°

7. [tex]m\widehat{AB}[/tex] = 50°,

The angle at the center of a circle is twice the angle subtended at the circumference, therefore;

m∠ADB = 50°/2 = 25°

m∠ADB = 25°

8. m∠CAD = 45°

The angle formed by an arc at the center of a circle theorem, indicates that we get;

[tex]m\widehat{CD}[/tex] = 2 × m∠CAD

[tex]m\widehat{CD}[/tex] = 2 × 45° = 90°

[tex]m\widehat{CD}[/tex] = 90°

9. m∠ACB = 70°

m∠ACB is the angle subtended by the arc [tex]m\widehat{AB}[/tex] on the circumference

Therefore;

[tex]m\widehat{AB}[/tex] = 2 × m∠ACB

[tex]m\widehat{AB}[/tex] = 2 × 70° = 140°

[tex]m\widehat{AB}[/tex] = 70°

10. m∠AOB = 80°, [tex]m\widehat{AB}[/tex] = 60°

m∠(AOB) = (1/2) × ([tex]m\widehat{AB}[/tex] + [tex]m\widehat{CD}[/tex])

Therefore; m∠(AOB) = 80° =  (1/2) × (60 + [tex]m\widehat{CD}[/tex])

80° =  (1/2) × (60 + [tex]m\widehat{CD}[/tex])

[tex]m\widehat{CD}[/tex] = 2 × 80° - 60° = 100°

[tex]m\widehat{CD}[/tex] = 100°

Total expense: 6500⋅40=260,000

Total profit: 344,000−260,000=84,000

Answer:

$84000

Step-by-step explanation:

40% of the cars would be 16 cars that are sold for $8000 each.

16×$8000=$128000

The remaining 60% of cars would be 24 cars to be sold at $9000 each.

24×$9000=$216000

The total profit = the sum - the amount he paid for all cars.

total profit = ($128000+$216000) - (40×$6500)

total profit = $344000 - $260000

Step-by-step explanation:

The function f(x) = 6log₂x - 3 increasing at the greatest rate in the interval [1/8, 1/2].

The maxima and minima of a function are the extreme values within the range; in other words, they are the maximum and minimum values of a function, respectively, at a given position.

Let the function be f(x) = 6log₂x - 3

For the interval x ∈ [2, 6]

f(x) ∈ [-0.678, 3]

For the interval x ∈ [1/8, 1/2]

f(x) ∈ [ -9.96, -5.32]

For the interval x ∈ [1, 2]

f(x) ∈ [-3, -0.67]

For the interval x∈ [1/2, 1]

f(x) ∈ [-5.32, -3]

The function increased most rapidly in the interval [1/8, 1/2], as can be seen from the function value and its interval values.

Therefore, the range [1/8, 1/2] is where the function f(x) = 6log₂x - 3 increases at the fastest pace.

The complete question

Ashton picked 6 pounds of pecans. He used 1/3 of the pecans in a soup recipe. Ashton puts the pecans that are left in 1/4 pound bags. How many bags of pecans does he have

If Kashif and Ali invested equal sums in the two different banks at 9 % and 10% , then in 6 years Ali will have $0.0945 more than Kashif .

We use the formula for compound interest, to calculate the amount that each person will have after 6 years  ;

Amount after 6 years for Kashif is :

⇒ A = P(1 + r/n[tex])^{nt}[/tex]

where A = (amount after 6 years) ; P = (initial investment)

r = interest rate = 9%  ; n = 1 ; t = time period (6 years) ;

So, A = P(1 + 0.09/1)⁶  ⇒ P(1.09)⁶  ;

Amount after 6 years for Ali is :

⇒ A = P(1 + 0.10/1)⁶ = P(1.10)⁶  ;

So , difference in the amounts that Kashif has compared to Ali after 6 years is  ⇒ P(1.09)⁶ - P(1.10)⁶  ;

Simplifying this expression, we get:

⇒ P(1.09⁶ - 1.10⁶)  ;

≈ -$0.0945     ;

Since the value is negative, it means that after 6 years, Ali will have more money than Kashif and difference between their amounts is approximately $0.0945    .
