When system of equations solved graphically, the solutions are points of interceptions, So here, the solution is the point of interception (0,-5).
Answer (0,-5).
To solve for the area of a triangle you use the formula A=b*h/2. The base for this triangle is 4 and the height is 8. Take 4*8 which is 32 and divide that answer in half to get 16 which is your answer.
Answer:
x= sine inverse of 0.75
Step-by-step explanation:
Pythagoras theorem
after that then using sine rule u can get ur angle x
Remember you can do anything as long as you do it to both sides
add 7 to both sides
x>5
the solution set could look like
x>5
or
S={x|x>5} or
(5,∞)
A=84 and r=1/5
Since r, the common ratio squared is less than one, the sum will converge to a limit. Rule: if r^2<1 infinite series converges, otherwise it diverges.
Since the sum of any geometric sequence is:
s(n)=a(1-r^n)/(1-r)
And if r^2<1, (1-r^n) becomes 1-0=1 as n approaches infinity.
So whenever r^2<1 the sum of the infinite series is just:
s(n)=a/(1-r)
Since a=84 and r=1/5 this infinite series has a sum of:
s(n)=84/(1-1/5)
s(n)=84/(4/5)
s(n)=5(84)/4
s(n)=105
