Alexander is correct. He uses P=2(l+w)
First you would have to get them to have the same denomitator so 2 3/4 is the same as 2 6/8 but u cant subtract 1 by 6 so u move 1 8/8 over from 5 1/8 and get 4 9/8 and then u subtract and get 2 3/8
This can be
solve using sine law, first solve the angle created at the steeple, x
X = 180 – 40 –
32
X = 108 degrees
Solve one side,
opposite to 32 degree angle, side a
Sine law:
Sin ( 32 ) / a =
sin ( 108) / 50
Solve for a
a = 27.86 m
then
sin (40) = h /
27.86
solve for h
<span>h = 17.91 m high
is the steeple</span>
Step-by-step explanation:
formula: gram of solute/gram of solution X 100
so 150/400 X 100 is <u>3</u><u>7</u><u>.</u><u>5</u><u>%</u><u> </u><u>of</u><u> </u><u>KNO3</u>
Graph
quadratic function is of the form
In our f(x) there is no x term and constant so we put 0
The value of a=1 , b=0 and c=0
To find vertex , use formula
Plug in the values
=0
Now plug in x=0 in f(x) equation
=0
So vertex is (0,0)
Now we pick some number for x below and above 0
Make a table
x y=x^2
-2 4
0 0
2 4
Now plot all the points (-2,4) (0,0) and (2,4)
The graph is attached below
