Answer:
error in step 1
Step-by-step explanation:
well where is does the step not make sense?
remember cos(pi) = -1 and sin(pi)=0
that means step 1 is strange... it didn't distribute properly
it should have been:
cos(pi) - cos(A)
hope that helps! ^-^
Answer:
a= -1 b=4 c = 5 y-int = -1, 5 x-int = 5
Step-by-step explanation:
In order to find a, b, and c you just look at the coefficients for the first second and third term in the equation. To find the y-intercepts you need to factor the equation down to (-x +5)(x + 1) then set both of those new equations equal to zero and solve. Lastly, to get the x-int just fill in 0 for every x in the problem and then simplify.
Answer:
75kg
Step-by-step explanation:
Decrease =25÷100×100kg
= 0.25×100kg
= 25kg
Decrease 100kg by 25%=100kg-25kg
= 75kg
Use the formula y2-y1/x2-x1 and sub in the points
Hope this helps
