Answer:
Step-by-step explanation:
We choose arbitrary values for x and in each case calculate y = 2x + 5.
If x = 0, y = 5; if x = 3, y = 11, and so on.
How? when x = 3, y = 2(3) + 5 = 6 + 5 = 11.
The table, with rows and columns suitable to this problem, would look like:
x y
0 5
3 11
10 25
and so on
Answer:
The answer is d.
Step-by-step explanation:
As we know, sin x= cos (90°-x)
sin 18° = cos (90°-18°)
= cos 72°.
Similarly, sin 72°= cos (90°-72°)
= cos 18°
But, sin 55°= cos (90°-55°)
= cos 35°
We know that
using a graph tool
see the attached figure
<span>The diver reaches the surface when d = 0
</span>so
<span>0.5t (3.5t- 28.25)=0---------> the solution is
0.5t=0--------> t=0
and
</span><span>(3.5t- 28.25)=0----------> 3.5t=28.25--------> t=28.25/3.5--------> t=8.07 minutes
</span><span>
the time it takes for the diver to reach the surface is when the depth is zero
the time is 8 minutes
the answer is
8 minutes</span>
The Answer Is 18
Order Of Operation laws says that you must do the parentheses first, 45x2.
45x2=90
The next thing you must do is divide 90 by 10 since division is before addition.
90/10=9
Now combine like terms.
9+9=18
