Well, let's first square 3.5x10^4 which is 1,225,000,000
Scientific notation is when you put a decimal place after the first digit and then say the answer is that multiplied by 10 to a power. This power is the number of digits that come after the first. In this case, the power should be 9 (if you count the 225 and all the 0's, you'll count 9 numbers).
Thus the answer is 1.225x10^9
√(t + 3) = 14 ← -2 both sides
t + 3 = 196 ← square both sides
t = 193 ← subtract 3 from both sides
5x² + 8x + 3 = 0 ← put in standard form
(5x + 3)(x + 1) = 0 ← factor
5x + 3 = 0 or x + 1 = 0 ←Zero product property
x =
![- \frac{3}{5}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B3%7D%7B5%7D%20)
or x = -1
Answer:
1 = 35
2 = 55
Step-by-step explanation:
so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do
180 - 90 = 90
this means the angle next to line 1 is also 90 degrees
then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do
55 + 90 = 145
180 - 145 = 35 degrees so angle 1 is 35 degrees
then we would find angle 2
90 - 35 = 55 degrees so angle 2 = 55
hope this helps : )
