Answer:
Here we don't have the options, so i will answer in a general way.
Every sentence that has the general structure like:
"something is greater than something"
"something is smaller than something"
"Something is no greater than something"
"something is no smaller than something"
There are a lot of other sentences, for example the ones like:
"N is at least equal to M" written as: N ≥ M
"N is at most equal to M" written as: N ≤ M
And there may be other ways to represent inequalities in sentences, but this is the most general way
Then the given sentence:
"One-half + k greater than 18"
This is written as:
1/2 + k > 18
Which is an inequality.
-5/8n= -0.4
Divde both sides by -5/8
n = 0.64
Algebra
The inverse of -9n is dividing by -9.
Answer:
10(3)^x
Step-by-step explanation:
The function contains the points (2,90) and (4,810). Use the general form y=abx to write two equations:
90=ab^2 and 810=ab^4
Solve each equation for a:
a=90/b^2 and a=810/b^4
Since a=a, set the other sides of the equations equal and solve for b.
90/b2=810/b4
Cross multiply, then divide and simplify as follows:
90b^4=810b^2
b^4/b^2=810/90
b^2=90
b^3
Now, use the value of b and the point (2,90) to find the value of a.
90=a(3^2)
a=10
So, substitute answers in original equation for a final answer of f(x)=10(3)^x.
Answer:
The area of the cover for the hot tub must be:
Step-by-step explanation:
First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:
- <u>Area of a circle = pi * radius ^ 2</u> (you must know that the radius is half the diameter)
Since the diameter is mentioned, it can be replaced in the formula:
- Area of a circle = 3.14 * (3.5 feet) ^ 2
- <u>Area of a circle = 38,465 square feet. Approximately 38 square feet</u>.
