Hello there!
Soo..to convert a number from standard notation to scientific notation you first have to write a decimal point in the number so that there is only one digit to the left of the decimal point. Sooo for example if u had 240,000 you would put the decimal after the 2 (2.40000)
Hope this helped and have a great day!!
Goodluck (:
Answer:
8
Step-by-step explanation:
0 = –x^2 + 4x – 2
This is of the form
ax^2 +bx +c
a = -1 b = 4 x = -2
The discriminant is
b^2 -4ac
4^2 - 4(-1)(-2)
16 - 8

Answer:
1.
Step-by-step explanation:
cos 30 = √3/2 (obtained from the 30-60-90 triangle)
sin 60 = √3/ 2 ( as above)
cot 60 = 1 / tan 60 = 1/√3 (as above)
So (cos30°+sin60°)cot60° = (√3/2 + √3/2) / √3
= 2√3/2 / √3
= √3 / √3
= 1.
