Answer:
In standard form 42=
In unit form, 42 as 4 tens 2 ones
Step-by-step explanation:
<u>Standard form</u>: It is the way of writing down the numbers easily in a very large or small numbers.
Rules for writing a number in standard form is that first you write down a number between 1 and 10, then multiply the number with 10(to the power of a number).
Now, to write
42 in standard form:
.
Unit form: it is a form that express the number by giving the number of place value within the number.
Unit form of 42:
42 is written as 4 tens , 2 ones.
Decimal fractions don't exist. Do you mean convert to a decimal and a fraction?
2 weeks, because the first week the second plant will grow to 6 inches and the first plant will grow to 7, the next week the first plant will be 8 inches and so will the second plant.
Factor:
2sin^2x-sinx = 0
sinx(2sinx - 1) = 0
Therefore the solutions are when:
sin x = 0
And
sinx = 1/2
So sinx = 0
is true when x = 0 and pi and all the angles coterminal with these points. Thus, the answer is x = pi*n, (where n is some integer)
sinx = 1/2
is true when x = pi/6 and 5pi/6 and the angles coterminal with these points.
Thus, the answer is x = pi/6 + 2pi*n (where n is some integer)
and x = 5pi/6 + 2pi*n (where n is some integer)
