I'll do 14 and 18, and you can apply those techniques for the other problems!
For 14, we get 30*(1/10^8). This means that you move the decimal place in 00.0000030.0 seven places to the left, resulting in 0.00000300
For 18, we can use the associative property of multiplication to get
5*3.5*10^3*10^(-1)=17.5*10^2. We get 10^2 by adding 3 and -1 up. Since it's positive 2, we simply move the decimal 2 places to the right to get 1750
So for this, we will be using the exponential equation formula, which is y=ab^x, with a = initial value and b = growth/decay. Since the value is increasing, you would add 1 and 0.02(2% in decimal form) together to get 1.02, which will be the b variable. And since we are starting in 2005 with $8 and trying to figure out the value in 2011, 8 will be the a variable and 6 will be the x variable (2011-2005=6)
With this info, our equation will be: y = 8(1.02)^6
Firstly, solve 1.02^6: y = 8(1.12616242)
Next, multiply and your answer will be (rounded to the hundreths): y = $9.01
When a square root of an expression is multiplied by itself, the result is that expression
-10 x 2 x 15
Calculate the product
-300

Step-by-step explanation:
we know that
The area of a circle is equal to
Part 1) Find the area of the circle with diameter 6 m
we have
-----> the radius is half the diameter
substitute the values
Part 2) Find the area of the circle with diameter 10 m
we have
-----> the radius is half the diameter
substitute the values
Part 3) Find the area of the circle with diameter 13 m
we have
-----> the radius is half the diameter
substitute the values

Step-by-step explanation:
To get a double of a number, we add the same number to itself. For example, double of 2 is 2 + 2 = 4. Example: Michelle has 4 marbles and Jane has double the marbles that Michelle has. ... It is easy to remember the numbers that we get by doubling one-digit numbers.
