Graph the relation {(5, 0), (0, 5), (5, 1), (1, 5)}. Is it a function? Why or why not?

MissTica

D. is the correct answer, as functions cannot have the same x value correspond to different y values. For a function to be considered a function, it must always pass the vertical line test.

What is a1 for the geometric sequence for which a8= -3584 and a3 = 112 ?

jasenka [17]

Answer:

The first term is 28.

Step-by-step explanation:

Given: 8th term of Geometric sequence , $a_8=-3584$

and 3rd term of Geometric Sequence, $a_3=112$

We have to find First term of given geometric Sequence.

Let a be the first term of geometric sequence.

We know that,

$a_n=ar^{n-1}$

So,

$\frac{a_8}{a_3}=\frac{ar^{8-1}}{ar^{3-1}}=\frac{-3584}{112}$

$\frac{r^{7}}{r^{2}}=-32$

$r^5=-32$

$r=-2$

So, $a_3=112$

$a\times(-2)^{2}=112$

$a=\frac{112}{4}=28$

Therefore, The first term is 28.

F(x)=∣x∣

elixir [45]

Answer:

Step-by-step explanation:

There are two transformations, one vertical, one horizontal.

The + 9 part outside the absolute value sign moves the graph up 9 units.

Replacing x with x - 1 moves the graph right 1 unit.

<em>Comment:</em> The horizontal shifts sometimes appear backwards: x - 1 looks like a shift to the left, but it's not.

Example: f(4) = |4| = 4. To get the same output (4) from g(x), you have to use a value for x that is 1 unit <u>larger</u> than 4. g(5) = |5 - 1| = 4.

Joe what's to build a fence for his dog Charlie he plans to surround the rectangle to the right with fence. How many feet will h

Aleksandr [31]

Joe wants to build a fence for his dog Charlie.
The lengths of the perimeter of the rectangle that he plans to surround with fence are as follows:

10 feet + 15 feet + 10 feet + 15 +feet.

The total perimeter area of a rectangle is worked out as follows:
10 + 15 + 10 + 15 = 50
Therefore Joe needs 50 feet of fencing to totally surround the rectangle with fence.
