WRITE 0,000003 56 IN SCIENTIFIC NOTATION ​
Elanso [62]

Answer:

3.56X10^-6

Step-by-step explanation:

In converting numbers to scientific notation, simply move the decimal point of the number until the numerical coefficient is greater than 1 but less than 10. Be sure to take note of the following:

1. The numerical coefficient.

2. Number of times we move the decimal point. It will be the exponent with the base of 10.

3. The direction we take in moving the decimal point. If the direction is to the right, take the negative sign for the exponent. If the direction is to the left, take the positive sign for the exponent.

Here, we move the decimal point of 0.00000356 to the right 6 times. So, we have now 3.56X10^-6.

Find f(x) and g(x) so the function can be expressed as y = f(g(x)).
elena55 [62]
Y=2/(x^2 +3)
g(x) = x^2 + 3 and f(x) = 2/x
fog(x) = f[g(x)]
= f(x^2 + 3)
= 2/(x^2 + 3)

It should be 12cm because

h=height
a=area
b=base

h=a/b we have base 15cm and height 8cm

8cm=a/15cm
8cm*15cm=a
120cm^2=a

we then use the area to find the height with base 10

h=a/b
h=120cm^2/10cm

h=12cm
