A. -f(1)=1,f(2)=2,f(n)=2f(n-1)f(n-2);n>2
You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
Answer:
Step-by-step explanation:
Sum of angle in a triangle = 180°
<A+<B+<C = 180
Given <B = 50°
Substituting into the formula
<A+50+<C = 180
<A+<C = 180-50
<A+<C = 130°
Since the ∆ABC is an acute triangle, the angles <A and <C must be angles less than 90° since acute angles are angles less than 90°
The possible values of <A and <C that will be acute and give a sum of 130° are;
∠A= 58° and ∠C= 72°
∠A= 80° and ∠C= 50°
∠A= 60° and ∠C= 70°
You can see that all the Angles are less than 90° and their sum is 130°
Answer:
b
Step-by-step explanation:
I Think B is the right answer
Answer:
h = b - 11.50
Step-by-step explanation:
Sharron(h) has 11.50 less than Rita(b)
h = b - 11.50
