How many significant figures are in the measured value 550,000,000?

1 answer:

NikAS [45]3 years ago

5 0

There are 2 significant figures (sig figs) which are the two '5' digits. The zeros aren't considered sig figs because we can write the number as 5.5 * 10^8 to represent the exact same idea. The 0's are simply placeholders to tell how big the number is, not necessarily how accurate it is. If the 0s were between the decimal point and a nonzero value, then the 0s would be significant. If the 0s were to the right of the decimal, then they would be significant.

Answer: 2

Which statement about g(x)=x^2-576 is true

Ipatiy [6.2K]

Answer:

c. the zeros, -24 and 24, can be found when 0= (x+24)(x-24).

Step-by-step explanation:

The given function is

$g(x)=x^2-576$

When we equate the function to zero, we obtai;

$x^2-576=0$

Use difference of two squares:

$x^2-24^2=0$

$(x-24)(x+24)=0$

Use the zero product property to obtain;

$x-24=0,\:and\:x+24=0$

This implies that;

$x=24,\:and\:x=-24$

The correct choice is C

olga_2 [115]

Answer:

the first option

Step-by-step explanation:

solution:

distance: d=1/4 lc (because is a quarter of a circle)

length of the circumference: lc=2 pi r

pi: constant=3.14

radius of the circle: r=80 feet

replacing pi and r in the formula of lc:

lc=2 pi r

lc=2 (3.14) (80 feet)

lc=502.4 feet

replacing lc in the formula of d:

d=1/4 lc

d=1/4 (502.4 feet)

d=502.4/4 feet

d=125.6 feet

So you need to divide 1000 by 125 which is 8. Which then you times by two to equal the two kilograms. So he needs to fill the cup up 16 times.
