The lowest common denominator of the two fractions is 4 because it is the smallest number that both fractions can be transformed into. 3/2 is multiplied by 2 to create 6/4 which can be added to 11/4.

Which sequence is modeled by the graph below?
Maru [420]

We have

a2 = 4

a3 = 2

a4 = 1

 calculate the difference

a3 - a2 = -2

a4 - a3 = -1

 The differences are not equal---------- >the sequence is not arithmetic.

 Getting the ratio:

a3/a2 = 0.5

a4/a3 = 0.5

 The common ratio is 0.5. Using the general form for a geometric series:

an = a1 r^(n-1)

for n = 2---------------- > a2=4

4 = a1 (0.5)^(2-1)

a1 = 8

therefore

an = 8 (1/2)^(n-1)

the answer is an = 8 (1/2)^(n-1)

the answer is none of those indicated in the question

Can somebody help me with this !!!!!!!thanks
dalvyx [7]

Given:

The graph of a parabola.

To find:

The domain, range and check whether it is a function or not.

Solution:

Domain: The set of x-values or input values is known as domain.

Range: The set of y-values or output values is known as range.

A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.

Vertical line test: Each vertical line intersect the graph at most once.

The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:

Domain=[-3,\infty)

The given function values can be any real number. So, the range of the given graph is:

Range=(-\infty,\infty)

For x=0, we have two values of the function because the graph intercept the y-axis at two points.

Since the graph does not pass the vertical line test therefore the given graph is not a function.

Triangle HIJ is similar to triangle KLM. Find the measure of side MK. Round your answer to the nearest tenth.
AnnZ [28]

Answer:

MK\approx 87.7

Step-by-step explanation:

By definition, similar polygons have corresponding sides in a constant proportion. Therefore, we can set up the following proportion (ratio of corresponding sides) to solve for MK:

\frac{20}{13}=\frac{MK}{57},\\MK=\frac{57\cdot 20}{13}\approx \boxed{87.7}
