Answers:
cos(A) = 0.8480
tan(B) = 1.6
=============================================
Explanation:
Before we can compute cos(A), we'll need to find the hypotenuse.
Use the pythagorean theorem.
a^2 + b^2 = c^2
8^2 + 5^2 = c^2
89 = c^2
c^2 = 89
c = sqrt(89)
The hypotenuse is exactly sqrt(89) units long.
This will allow us to find the cos(A) value
cos(angle) = adjacent/hypotenuse
cos(A) = AC/AB
cos(A) = 8/sqrt(89)
cos(A) = 0.84799830400509 which is approximate
cos(A) = 0.8480 when rounding to four decimal places
-------------------------
For the tangent ratio, we won't use the hypotenuse. Instead, we use the opposite and adjacent sides like so:
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 8/5
tan(B) = 1.6
Answer:
the mean of 8 children = mean of 5 boys + mean of 3 girls / 2
10.5 + 9.5 / 2
20 / 2
= 10 kg
therefore mean of 8 children is 10 kg
Answer:
x^6 - 7x^5 + 69/4x^4 + -35/2x^3 + 25/4x^2
Step-by-step explanation:
x^2(x-1)^2(x-5/2)^2 is the factored form of the polynomial. Now you simplify it to convert to standard form.
The equation would be y=1/3x. The slope rises 1 unit for every 3 units it moves right.
