Answer:

3.2 x 10^13

Step-by-step explanation:

(8x10^4)(4x10^8)

reorder the terms using the commutative property

(8x4)x(10^4x10^8)

multiply

32x (10^4 x 10^8)

= 32 x 10^4+8

= 32 x 10^12

now convert to scientific notation

=3.2 x 10^13

Is the graph a linear function, non linear function, or relation
serious [3.7K]

a LINEar function has well, the graph of a straight line, so this isn't that.

is it a relation? well, yes, because the y-value correlates with the x-value, so one depends or relates to the other.

is it a non-linear function?  well, a function has to pass the <u>vertical line test</u>, meaning if we draw vertical lines they must touch the graph only once on their way down.... and in this case it seems they do, so it is non-linear clearly, and it's also a function.

In the given figure, if y = 30, find (i) x (ii) z and (iii) u​
pogonyaev

Answer:

u=30

x=150

z=150

y=30

Step-by-step explanation:

u=y [ being vertically opposite angle]

x+u=180[ being linear pair]

x+30=180

x=180-30

x=150

z=x[being vertically opposite angle]

z=150

y=u[ being voa]

Please help find missing side length
maria [59]

Answer:

The missing side length is 6.

Step-by-step explanation:

Because the two triangles are similar,

the following equation of ratios is true:

m        4

----- = -----

15       10

Cross-multiplying, we get:

10m = 60, or m = 60/10 = 6

The missing side length is 6.
