I do know the bottom one is 2.8
Top is 1.6
I don’t know the middle one
Answer:
a = 1, b = 3.
Step-by-step explanation:
a + b = 4
a - b = -2 Adding to eliminate b:
2a = 2
a = 1
So 1 + b = 4
giving b = 3.
c^2 = a^2 + b^2 - 2(ab)(cos C)
c^2 + 2(ab)(cos C) = a^2 + b^2
2(ab)(cos C) = a^2 + b^2 - c^2
cos C = (a^2 + b^2 - c^2) / 2ab - Answer choice E
Hope this helps! :)
We know that
<span>Trinomial of degree 35 means a polynomial
that
a) Having three terms
b) highest degree is 35
examples
x</span>^35+x³+3
x^35+2x-8
x^35+x²+2
etc
About $0.48
you can make an equation
12/5.79 = 1/x
