A string running from the ground to the top of a fence has an angle of elevation of 45°. The string is 10 feet long. What is the

Elza [17]

Answer: The distance between the fence and where the string is pegged to the ground is 7.07 feet.

Step-by-step explanation:

Since we have given that

Length of string = 10 feet

Angle of elevation = 45°

We need to find the distance between the fence and where the string is pegged to the ground.

We will apply "Cosine formula "

$\cos 45^\circ=\dfrac{Base}{Hypotenuse}\\\\\dfrac{1}{\sqrt{2}}=\dfrac{Base}{10}\\\\Base=\dfrac{10}{\sqrt{2}}\\\\Base=7.07\ feet$

Hence, the distance between the fence and where the string is pegged to the ground is 7.07 feet.

A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year

Andru [333]

Answer:

$y = 18 * 1.15^x$

Step-by-step explanation:

Given

$a = 18$ --- initial

$r =15\%$ -- rate

Value after a year = $20.70

Required

Expression to calculate its value after y years

This is calculated using:

$y = ab^x$

Where

$b=1 +r$

Substitute $r =15\%$ in $b=1 +r$

$b = 1 + 15\%$

$b = 1 + 0.15$

$b = 1.15$

Substitute $b = 1.15$ and $a = 18$ in $y = ab^x$

$y = 18 * 1.15^x$
