Answer:

Step-by-step explanation:

The standard form of this exponential function is

$y=a(b)^x$ where a is the initial value and b is the growth rate. Our initial value is 490 and our growth rate is .2 so the equation is

$y=490(.2)^x$

Answer:

30.48 miles

Step-by-step explanation:

This can be represented as a right angle triangle with sides 20 miles and 23 miles. The hypotenuse is the distance from the starting point. Pythagoras theorem states that for a right-angled triangle, the square of side of the hypotenuse is equal to the sum of squares of the other two sides. It is given by the equation:

c² = a² + b², where c is the hypotenuse and a,b are the sides

Let a = 20 miles and b = 23 miles

c² = a² + b²

c² = 20² + 23²

c² = 400 + 529

c² = 929

c = √929 = 30.48

c = 30.48 miles

What is the value of z?

weqwewe [10]

Answer:

z = 30.45 feet

Step-by-step explanation:

The volume (V) of a triangular prism is calculated as

V = area of triangular end (A) × length

Here V = 913.5 and length = 15, thus

A × 15 = 913.5 ( divide both sides by 15 )

A = 60.9 ft²

The area of the triangle = $\frac{1}{2}$ bh ( b is the base and h the height ), thus

$\frac{1}{2}$ × 4 × z = 60.9

2z = 60.9 ( divide both sides by 2 )

z = 30.45

From 170 to 97, there's a difference of 73.

so hmm if we take 170 to be the 100%, what is 73 in percentage off of it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
170&100\\
73&p
\end{array}\cfrac{170}{73}=\cfrac{100}{p}\implies p=\cfrac{73\cdot 100}{170}$
