What is indicated by arrowheads on a line?

1 answer:

5 0

Arrows on a line mean that the line continues forever in that direction. If there are two arrows in both directions along a line, then you have a geometric line. If you only have one arrow, then it is a ray. Having no arrows indicates a segment.

prem gave 1/3 of his property for charity of the rest he gave 2/3 to his wife and rest divided equally between his son and daugh

Anna11 [10]

Given parameters:

Fraction given to charity = $\frac{1}{3}$

Fraction given to wife = $\frac{2}{3}$

Unknown:

Fraction given to son and daughter =?

Solution:

Let the total property = x

Fraction given to charity = $\frac{1}{3} x$

Fraction given to wife = $\frac{2}{3} x$

The remaining was given to son and daughter = F

So;

Total property = fraction given to charity + fraction given to wife + fraction given to son and daughter

x = $\frac{1}{3} x + \frac{2}{3} x + F$

F = x - ( $\frac{1}{3} x + \frac{2}{3} x$ )

F = 0

The son and daughter will not inherit anything

The product of two positive integers plus their sum is 95. The integers are relatively prime, and each is less than 20. What is

creativ13 [48]

Let the fist integer be x, the second is x+20
the product of the numbers is:
x(x+20)
the sum of the numbers is:
x+x+20=2x+20
the sum of the above operations will give us:
2x+20+x^2+20x=95
x^2+22x+20=95
this can be written as quadratic to be:
x^2+22x-75=0
solving the above we get:
x=3 and x=-25
but since the integers should be positive, then x=3
the second number is x+20=3+20=23
hence the numbers are:
3 and 23

tatuchka [14]

Answer:

dy/dx = d/dx (sin3x.cos2x)

dy/dx = cos3x . 3 . -sin2x . 2 (Using chain rule)

dy/dx = -6cos3xsin2x
