Answer:
Step-by-step explanation:
Note*
To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. To evaluate, substitute 3 for x in the expression, and then simplify.
Let's see if we can't be logical here......Pick a formula and see what it yields. For example, choose D.
For n = 1 ---> -1 x 4^1 ----> -1 x 4 = -4, when the correct value is 1. Therefore D is out.
Try C. For n = 1 ---> 1 x 4^(1-1) ---> 1 x 4^0 ----> 1 x1 ---> 1, So it is correct for n =1. How about
n=2? 1 x 4^(2-1) = 1 x 4^1 = 1 x 4 = 4, when the correct answer is -4. Therefore C is out
I'm sure you can do the remaining two choices....
This equation is a direct variation. If y increases, x increases. The constant of variation is 4 I think. Hope that helped.
Answer:
150 squared yards
Step-by-step explanation:
To get the area of something you need to multiple the width and the length of that something.
The scale for he game room is 1 ft: 5 yd.
Multiple 5 yd for every foot.
You get 10 yd as your height and 15 yd as your length.
Multiple 10 and 15 to get the area.
10*15=150 squared yards
P1/T1 = P2/T2
<span>748 / 525 = P2/293 </span>
<span>P2 = 748/525 X 293 = 417.455 kPa </span>
