How do you write 19,830 in scientific notation? × 10^

1.983(10⁴)

Step-by-step explanation:

Since we need to have ones and decimals as proper scientific notation, we have 1.983. Since we need the value of 19830, we need to move the decimal place 4 places to the right, so our exponent is 4.

*I double checked my work this time.

1.983 * 10 ^4

Step-by-step explanation:

19,830

Move the decimal so there is only 1 digit before the decimal

We move it 4 places to the left

1.9830

The exponent is the number of places moved, since it was moved to the left the exponent is positive

1.983 * 10 ^4

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

-14 is the answer

hope this : ))
