Does this graph represent a function? Why or why not?

Mathematics

Answer:

Yes, this graph represents a function.

Functions can have a maximum of one y-value for every x-value. On a graph, this means it passes the vertical line test.

Step-by-step explanation:

The vertical line test is when a vertical line is passed though the graph. If at any point the vertical line touch more than one point on the graph, the graph is not a function. Vertical line test is also known as VLT.

3/8 is 4 & 3/5 % of what number? (Round to the nearest hundredth.)
Harman [31]

Answer:

n = 8.15

Step-by-step explanation:

3/8 is 4 & 3/5 % of what number?

Rewrite this as:    3/8 is (4  3/5)% of what number?

Convert 4 3/5% into a decimal:  0.046

Then write out and solve the equation 3/8 = 0.046n, where n is the unknown number.

Dividing both sides by 0.046, we get n = 8.15

Pablo generates the function f(x) = 3/2(5/2)^x-1 to determine the x'th number in a sequence.
BaLLatris [955]

Answer:

A.

f(x+1)=5/2f(x) with f(1)=3/2

Step-by-step explanation:

So we are looking for a recursive form of

f(x)=\frac{3}{2}(\frac{5}{2})^{x-1}.

This is the explicit form of a geometric sequence where r=5/2 and a_1=\frac{3}{2}.

The general form of an explicit equation for a geometric sequence is

a_1(r)^{n-1} \text{ where } a_1 \text{ is the first term and } r \text{ is the common ratio}.

The recursive form of that sequence is:

a_{n+1}=ra_n \text{ where you give the first term value for } a_1.

So we have r=5/2 here so the answer is A.

f(x+1)=5/2f(x) with f(1)=3/2

By the way all this says is term is equal to 5/2 times previous term.
