Answer:

2 x

Step-by-step explanation:

A simple way of determining a derivative of an expression is that the power is brought down and the new power is reduced by 1. For example,

d/dx [x^3] = 3x^2.

d/dx [2x^3] = 2(3)x^2

= 6x^2

Hence derivative if x^2 = 2x^1 = <u>2</u><u>x</u>

german

Answer:

365.73 miles

Step-by-step explanation:

Given that :

Angle of elevation (western high) = 41.25°

Angle of elevation (pine high) = 23.125

From the diagram attached :

Angle A = 180 - (41.25 + 13.125) = 115.625

Using the Sine rule :

a / SinA = b/SinB = c/sin C

512 / sin 115.625 = b / sin 41.25

554.68738 = b / sin 41.25

554.68738 * sin 41. 25 = b

b = 365.73 miles

Larry buys a tent that is on sale for 25% off the original price. The original price is $80 more than the sale price. What is th

myrzilka [38]

Answer:

The original price of the tent = $320

Step-by-step explanation:

Let the original price be =$ $x$

Discount offered = $25$ % of the orignal price = $\frac{25}{100}\times x=0.25\times x =\$ 0.25x$

Original price is $80 more than sale price

Discount = Original price - Sale price = $80

So, we have

$0.25x=80$

We need to solve for $x$ to find original price

Dividing both sides by $0.25$

$\frac{0.25}{0.25}x=\frac{80}{0.25}\\x=\$320$

∴ The original price of the tent = $320

How do you find the width of a rectangle when the perimeter is given?

ololo11 [35]

Usually you are given more information about the rectangle such as distance of length in terms of width.

You know that the formula for perimeter is

P=2(l+w)

Substitute p and the other values to find width.

Hope I helped :)
