14 Hamburgers because if you multiply 38 by 2 because it was hamburgers AND cheesburgers, you would get 76...then subtract 62 from 76 and you get 14

4. Here are the equations that define three functions.

luda_lava [24]

The functions f(x), g(x) and h(x) are all linear functions

The function value that is largest is h(-100)
The function value that is largest is h(-100)
The function value that is largest is f(1/100)

<h3>How to determine the function with the largest values</h3>

The functions are given as:

$f(x) = 4x - 5$

$g(x) = 4(x - 5)$

$h(x) = x/4 -5$

At x = 100, we have:

$f(100) = 4 * 100 - 5 = 395$

$g(100) = 4 * (100 - 5) = 380$

$h(100) = 100/4 - 5 = 20$

Hence, the function value that is largest is f(100)

At x = -100, we have:

$f(-100) = -4 * 100 - 5 = -405$

$g(-100) = 4 * (-100 - 5) = -420$

$h(-100) = -100/4 - 5 = -30$

Hence, the function value that is largest is h(-100)

At x = 1/100, we have:

$f(1/100) = 4/100 - 5 = -4.96$

$g(1/100) = 4 * (1/100 - 5) = -19.96$

$h(1/100) = (1/100)/4 - 5 = -4.9975$

Hence, the function value that is largest is f(1/100)

Find the surface area of a square pyramid with side length 3 cm and slant height 3 cm

ipn [44]

Answer:

Step-by-step explanation:

base length b = 3 in

slant height L = 3 in

base area = b² = 3² = 9 in²

lateral area = 4·½bL = 4·½·3·3 = 18 in²

surface area = base area + lateral area = 27 in²

If the cost of an item increased by a percentage and decreased by the same percentage, what would that percentage be if the new

Orlov [11]

The percentage, if the new cost was 84% of the original is 40%

Let the cost of the item be x.

When the price increased by y%, the new price is:

$New =x \times (1 + y\%)$

When the price decreased by the same percentage (i.e. y%), the new price is:

$New =x \times (1 + y\%) \times (1 - y\%)$

The cost is said to be 84% of the original price.

So, we have:

$x \times (1 + y\%) \times (1 - y\%) =84\% \times x$

Divide both sides by x

$(1 + y\%) \times (1 - y\%) =84\%$

Apply the difference of two squares

$1 - (y\%)^2 =84\% \\\\$

Subtract 1 from both sides of the equation

$- (y\%)^2 =-16\%$

Cancel out the common factors

$(y\%)^2 =16\%$

Take the square root of both sides

$y\% =0.4$

Multiply both sides by 100

$y =40$

Hence, the percentage is 40%
