Answer:

Step-by-step explanation:

As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.

Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)

The option A is incorrect due to the same problem for the point (8,7)

The correct option is D.

Diff Eq dy/dx= (ycos(x))/(1+y^2) initial condition is y(0)=1 work below ...?

Volgvan

Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2

Nigel is planning his training schedule for a marathon over a 4-day period. He is uncertain how many miles he will run on two da

KengaRu [80]

Answer:

$12+17+y+z$ or $29+y+z$ .

Step-by-step explanation:

We have been given that Nigel is planning his training schedule for a marathon over a 4-day period. He is uncertain how many miles he will run on two days. One expression for the total miles he will run is $12+y+17+z$ .

The Commutative Property of Addition states that we can add numbers in any order. For example a and b be two numbers.

According to Commutative Property of Addition $a+b=b+a$ .

Similarly, we can write an equivalent expression to our given expression as:

$12+17+y+z$

We can simplify our expression as:

$29+y+z$ .

Therefore, our required expression would be $12+17+y+z$ or $29+y+z$ .

Answer:

Step-by-step explanation:

add up all the inside angels, you'll get 122, subtract that from the total area of the triangle which is 180. you will have 58 for your missong inside triangle. the outside line makes 180 with the angel we just found, so subtract 58 from 180 and you get 122. check out Khan Academy for help.

Ok, so remember the exponentioal law that says
