The correct answer is C) n- 0.18
Answer:
Step-by-step explanation:
Using the section formula, if a point (x,y) divides the line joining the points (x
1
,y
1
) and (x
2
,y
2
) in the ratio m:n, then
(x,y)=(

The vertices of the triangle are given to be (x
1
,y
1
),(x

) and (x
3
,y
3
). Let these vertices be A,B and C respectively.
Then the coordinates of the point P that divides AB in l:k will be

Answer:
Bryson’s age is 14 years
Step-by-step explanation:
Let
x ----> Bryson’s age
we know that
Bryson’s age multiplied by 3 minus 4 must be equal to 38
so
The linear equation that represent this situation is
solve for x
Adds 4 both sides
Divide by 3 both sides
therefore
Bryson’s age is 14 years
Sin Q = oppo. / hypo
sin Q = 9/15
sin Q = 0.6
Answer:
4.52 x 10^-7
Step-by-step explanation:
you have a very small number (numbers to right of decimal) so you're exponent will be negative.
