The difference between the set of non-negative real numbers and the set of positive real numbers is:
Inessa05 [86]

Answer:

C; A singleton set

Step-by-step explanation:

Mathematically, when a number is non-negative; it is either positive or zero

Now, this is because 0 identifies as neither a positive or a negative number

hence, when we find the difference between the two sets, the only number that stands out unmatched is the value 0

What this mean is that we are having a set with a single number result

So we have our answer as {0}

A bag holds 12 red marbles, 11 green marbles, 17 blue marbles, and 5 yellow marbles. What is the probability that you will NOT c
grigory [225]
The probability that you will NOT choose a blue marble is 28/45.
45 because there are 45 marbles in total 12+11+17+5=45
And then 28 because you add all the marbles that are NOT blue 12+11+5=28

Does the point (-5, 3) satisfy the equation y = x − 8?
o-na [289]
No. This is because you can plug it in and see if it is true. Meaning...
3=-5-8
3=-13
3 is not equal to -13. Therefore the point does not satisfy the equation

What is an equation with more than one variable called
Eddi Din [679]

Answer: a. a literal equation


Step-by-step explanation:

A literal equation is an equation which comprises basically of letters., where letters are nothing but variables.

All the kinds of formulas are said to be examples of literal equations.

For example slope intercept form y=mx+c

The rate of change of position on a straight line r=\frac{d}{t}, where 'd' is the distance and 't' is the time.

Therefore, a literal equation is an equation with more than one variables.

Evaluate the line integral, where C is the given curve. C sin(x) dx + cos(y) dy, where C consists of the top half of the circle
kenny6666 [7]

Parameterize the circular part of C (call it C_1) by

x=4\cos t

y=4\sin t

wih 0\le t\le\pi, and the linear part (call it C_2) by

x=-4-t

y=4t

with 0\le t\le1.

Then

\displaystyle\int_C\sin x\,\mathrm dx+\cos y\,\mathrm dy=\left\{\int_{C_1}+\int_{C_2}\right\}\sin x\,\mathrm dx+\cos y\,\mathrm dy

=\displaystyle\int_0^\pi(-4\sin t\sin(4\cos t)+4\cos t\cos(4\sin t))\,\mathrm dt+\int_0^1(-\sin(-4-t)+\cos4t)\,\mathrm dt

=0+\displaystyle\int_0^1(\sin(t+4)+\cos4t)\,\mathrm dt

=\cos4-\cos5+\dfrac{\sin4}4
