Answer:

Both answers are 3.

Step-by-step explanation:

10^3 = 10 * 10 * 10 = 1000

When you multiply 42.12 by 10^3, you are multiplying 42.12 by 1000.

When you multiply a number by a power of 10, such as 10, 100, 1000, etc., move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10.

42.12 * 1000 = 42,120

I need help on this please
ziro4ka [17]

Answer:

See answers below

Step-by-step explanation:

From the given functions, the equivalent function for when x = 0 is -(x-1)²

h(x) = -(x-1)²

h(0) = -(0-1)²

h(0)= -(-1)²

h(0) = -1

when x = 2, the equivalent function is -1/2x - 1

h(x) =  -1/2x - 1

h(2) =  -1/2(2) - 1

h(2) = -1-1

h(2) = -2

when x = 5, the equivalent function is -1/2x - 1

h(x) =  -1/2x - 1

h(5) =  -1/2(5) - 1

h(5) = -5/2-1

h(5) = -7/2

Solve the following proportions<br> 3/x-3=8/2x+6<br> X=
Rzqust [24]

Answer:

21

Step-by-step explanation:

3/(x-3) = 8/(2x+6)

or, 3(2x+6) = 8(x-3)   ( by cross multiplication)

or, 6x + 18 = 8x - 24

or, 8x - 6x = 24 + 18

or, 2x = 42

or, x = 42/2

=21
