I would say Linear because there is no clear non linear pattern! alternatively, you could put the data into a spreadsheet and calculate the R value (pearson's coefficient) then see how strong the linearity is. In short, I would say Linear! hope that helps :)

Answer: non linear

Step-by-step explanation:

It’s difficult to tell because the dots are big and the scale is too small, but the plot should be a decreasing function with negative concavity until x=70 aprox where there is an assyptote. Then, after x=70 we only have one point so we don’t know how it continues.

Which of the following statements is true if m∠E = m∠Y and m∠F = m∠X?

mars1129 [50]

Answer:

segment FE over segment XY equals segment EG over segment YZ equals segment GF over segment ZX

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

If m∠E = m∠Y and m∠F = m∠X

then

Triangles EFG and YXZ are similar by AA Similarity Theorem

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

The corresponding sides are

FE and XY

EG and YZ

GF and ZX

so therefore

segment FE over segment XY equals segment EG over segment YZ equals segment GF over segment ZX Firstly , let us learn about trigonometry in mathematics.

Suppose the ΔABC is a right triangle and ∠A is 90°.

sin ∠A = opposite / hypotenuse

cos ∠A = adjacent / hypotenuse

tan ∠A = opposite / adjacent

Let us now tackle the problem!

A similar triangle has the same angle, in other words the triangle has the same shape but different sizes.

From the figure in the attachment , we can conclude that:

m∠E = m∠Y

m∠F= m∠X

m∠G = m∠Z

∴ ΔEFG ~ ΔYXZ ( ΔEFG is similar to ΔYXZ )

Because of the similarity , then:

FE : XY = EG : YZ = GF : ZX

Conclusion:

ΔFG is similar to ΔYXZ.

Segment FE over segment XY equals segment EG over segment YZ equals segment GF over segment ZX , i.e:

Find the value of x in the triangle shown below. 56° 4 4.5 4

svetlana [45]

Step-by-step explanation:

$\frac{ \sin(56) }{4} = \frac{ \sin(x) }{4.5} \\ \sin(x ) = \frac{4.5 \times \sin(56) }{4} = \frac{3.73}{4} \\ \sin(x) = 0.9326 \\ x = 68.84$

Which relation defined by a set of ordered pairs is not a function?

IRINA_888 [86]

The answer is: [C]:
___________________________________________________________
"{(1, –1), (2, –2), (0, 0), (1, 1), (2, 2)} " {(1, –1), (2, –2), (0, 0), (1, 1), (2, 2)}" .
__________________________________________________________
This set of ordered pairs is NOT a function because their is one x-coordinate in this set that has multiple y-coordinates;
specifically: "(1, -1)" ; and "(1, 1)".
__________________________________________________________
All of the other answer choices given are functions.
