Answer:
4 1/2 hours
Step-by-step explanation:
Pragnesh = 30 minutes
Qazi = 1 1/2 hours
Ronghui = 2 1/2 hours
add them and that gets you 4 1/2 hours. You can also check this yourself by putting this in the number problem. :)
To get the answer, you have to multiply 1,817.43 by 0.0344 (decimal form of 3.44%). So that would equal 62.52.
B. $62.52
Answer:
£20
Step-by-step explanation:
1-1/4=3/4
3/4=15
1
1*15/3/4
15*4/3=20
An exponent is customarily indcated using a caret (^), the character above the "6" on most keyboards. People like to write your first term as sin^2(x), but it is perhaps better written as sin(x)^2, the square of sin(x). Note that parentheses are required to identify the argument of the sine function.
You can let some variable stand for sin(x), such as ...
.. z = sin(x)
Now, the expression can be written as
.. z^2 +z -2
This quadratic expression can be factored in the usual way: find two factors of -2 (the constant term) that add to +1 (the coefficient of z).
You know
.. -2 = -1*2 = -2*1
The first factor pair (-1, 2) sums to +1, so we can write the factorization as
.. z^2 +z -2 = (z -1)(z +2)
In terms of the trig function, this is
.. sin(x)^2 +sin(x) -2 = (sin(x) -1)*(sin(x) +2)
