The TIME function is included as part of Excel's Date and Time features. With the assistance of TIME, we are able to create a time by employing various components for the hours, minutes, and seconds.

While conducting financial analysis, it's possible that we'll need to date a report. Under these conditions, the TIME function may be used to convert a text string into a format that presents the time as a decimal representation of the seconds, minutes, and hours. Additionally, the function's capabilities include the ability to merge several values into a single time value.

formula= TIME (hour, minute, second)

distance = rate X time

D = RT

T = D/R

20 feet per second = 1200 feet per minute

16 feet per second = 960 feet per minute

(D/R) + 19 + (D/R) = 21

(D/R) + 19 + (D/R) = 21

(D/1200) + 19 + (D/960) = 21,

This is the equation we can use to find the distance from the flowerbed to the​ hive.

(D/1200) + (D/960) = 2

(D(1200)(960))/1200 + (D(1200)(960))/960 = 2(1200)960

960D + 1200D = 5(1200)960

2,160D = 2304000

D=1066.66667

Sam would need to drive for the two plans to cost the same is 130 miles.

Let, x = Number of miles driven

      y = Total cost

The first plan:

Initial fee = $65

Cost of 1 mile = $0.3

Cost of drive x mile = $0.3x

In total, you will pay

y = 0.3x + 65 for the first plan.

The second plan:

There are no initial costs, but

Cost of 1 mile = $0.80

y = 0.80x

Now we have two equations

y = 0.3x + 65

y = 0.80x

As we know that y is equal to both 0.3x + 65 and 0.80x, this means we can equate the right hand sides and solve for x.

    0.3x + 65 = 0.80x

0.80x - 0.3x = 65

            0.5x = 65

                 x =  65÷0.5

                 x =  130

The cost of two plans will be same when Sam drive 130 miles.

The vertex F(−2, 4) in the dilated image has coordinates of (−6, 12) option (B) F' is correct.

The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.

It is given that:

The coordinates are:

Rectangle EFGH has vertices E(−3, 4), F(−2, 4), G(−2, −2), and H(−3, −2).

After applying dilation with a scale factor of 3:

E(−3, 4) → E'(-3x3, 4x3) = E'(-9, 12)

Similarly,

F(−2, 4) → F'(-6, 12)

G(−2, −2) → G'(-6, -6)

H(−3, −2) → H'(-9, -6)

Thus, the vertex F(−2, 4) in the dilated image has coordinates of (−6, 12) option (B) F' is correct.

Answer: 20/12

Step-by-step explanation:

A composite function exists as a function that depends on another function. The value for (f(1+h)-f(1)) / h = 2

In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.

Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.

Let the function be f(x) = 2x - 3

f(1+h) = 2 (1+h) -3 = 2h - 1

f(1) = 2(1) - 3 = -1

(f(1+h)-f(1)) = (2h - 1 ) + ( -1) = 2h

simplifying the equation, we get

(f(1+h)-f(1)) / h = 2h/ h

(f(1+h)-f(1))/h = 2

Therefore, the value of (f(1+h)-f(1))/h = 2.

The multiplication of the expression ( 3 + √2)( 4 +√2 ) is 14 + 7√2.

Multiplication in elementary algebra is the process of figuring out the outcome of multiplying a number by a number b. The product of a and b is the outcome of multiplication, and each of the integers a and b is referred to as a factor of the product ab.

Consider the expression,

y = ( 3 + √2)( 4 +√2 )

Using the distributive property,

a( b + c ) = ab + ac

y = ( 3 + √2)( 4 +√2 )

y = 3( 4 + √2 ) + √2( 4 + √2 )

y = 3 × 4 + 3 × √2 + √2 × 4 + ( √2 )²

y = 12 + 3√2 + 4√2 + 2

y = 14 + √2( 3 + 4 )

y = 14 + 7√2

The total cost of the laptop, including the sales tax, is $974.57.

The total cost of the laptop is the addition of the listed price and the sales tax (dollars).

The listed price refers to the retailer's (seller's) price before the addition of the sales tax.

After adding the sales tax to the listed price, the total cost is obtained.

Therefore, sales tax, which is a proportional tax, increases the cost of goods and services to consumers.

Listed price before tax = $887.99

Sales tax rate = 9.75%

Total cost after tax = $974.57 ($887.99 x 1.0975)

Thus, the total cost of the laptop after factoring in the sales tax is $974.57.
