Answer:
1: proportional
2: non-proportional
3: non-proportional
4: non-proportional
5: proportional
6: proportional
7: non-proportional
8: proportional
9. proportional.
10. proportional.
11. non-proportional.
12. proportional.
Step-by-step explanation:
I'm unsure how the proportional ones are actually calculated depending if it requires a dot on the exact origin, but depending on what I can graphically view and assume; every graph with the line running through the origin is proportional and every graph where the line does not run through the origin is non-proportional.
Answer:
Step-by-step explanation:
As for the angles of both triangles; they’re the same. The sides are 1:2.
I’m giving you formulas that are labeled: side a shortest
” b mid length
” c hypotenuse
angle α(alpha) opposite side a
” β(beta) ” ” b
” γ(gamma) ” ” c
A major formula for rt triangles is: a^2+b^2=c^2.
*Another is: a/sinα=b/sinβ=c/sinγ.
Remember α+β+γ=180°.
As for sides a&b use the above formula.
As for <ACB; the angle is γ which is a rt <.
Given: tan<x=5/2+1/2=6/2=3atan=71.565……….°=β. So α=18.44…….°. γ= rt angle.
To get the sides use the formulas at *.
Answer:
2(7) = 14
Step-by-step explanation:
When there is a number in the brackets, we want to input that into our function and get the output. In other words, we simply substitute 7 for x
2(7) = 14
-0.027 is the answer, basically you would just count out the zeros behind the decimal since it's 100, you would place one zero to create the "hundredths" place
