If i were you, I would just plug these into my calculator.
1. 1.587
2. 11.469
3. 6.503
4. 1.81
5. 28.984
Answer:
6400
Step-by-step explanation:
so every 5 hours it gains 800 bacteria so 4800+800=5600 (hour 10)
and 5600+800=6400 (hour 15)
Answer:
29.56
Step-by-step explanation:
From the given diagram
x = hypotenuse
27 = adjacent
Using SOH CAH TOA identity
cos theta = adj/hyp.
Cos 24 = 27/x
x = 27/cos24
x = 29.56
Hence the value of x to the hundredth place is 29.56
A trapezium has a pair of parallel sides.
Step-by-step explanation:
this is really simple : we only need to put the given x and y coordinate values into both equations and see, if both equations remain true.
(-2, -1) means x = -2, y = -1
first equation :
-1 = 3×-2 + 5 = -6 + 5 = -1
so, -1 = -1
true.
second equation :
-2 + -1 = -3
-3 = -3
true.
therefore, (-2, -1) is a solution to the linear system.
the point is the crossing point of both lines.
