Answer:
x ≈ 31.0°
Step-by-step explanation:
From the right triangle given in the picture,
By applying tangent rule,
tan(x) = 
tan(x) = 
x = 
x = 
x = 30.96
x ≈ 31.0°
Therefore, measure of angle x is 30.0°
<em><u>ANSWER</u></em>
x° + 74° + 90° = 180°(Angles in a triangle)
x° + 164° = 180°
x° + 164° - 164° = 180° - 164°
x° = 16°
Answer:
354.
Step-by-step explanation:
Exponential growth:
380 = 200e^(k*9) where k is a constant to be found.
e^9k = 380/200 = 19/10
ln e^9k = ln 1.9
9k = ln 1.9
k = ln 1.9 / 9
k = 0.071
After 8 hours:
Number of bacteria =
200*e^(8*0.071)
= 354.
Answer:
1)Take the smallest power common
2) simply the bracket
3) multiply with the power taken common
Example:
5×10⁶ - 4×10³
Smaller power is 3, so take 10³ common:
10³[(5×10²) - 4]
10³[500 - 4]
10³(496)
496×10³
4.96×10⁵
