Diep is saving money so he can buy a used car in 12 months. The total cost of the car he wants is $1,450. Diep determines that he needs to save $120 each month to be able to afford the car, as shown below.
12 StartLongDivisionSymbol 1450 EndLongDivisionSymbol minus 12 = 25. 25 minus 25 = a remainder of 0 and a quotient of 120.
What error did Diep make?
There is a subtraction error. Diep will need to save less than $120 each month.
There is a subtraction error. Diep will need to save exactly $121 each month.
There is a multiplication error. Diep needs to save exactly $120.83 each month.
There is a multiplication error. Diep needs to save an average of 120.8 dollars ModifyingAbove 3 with bar each month. Some months he needs to save $120.83 and other months he needs to save $120.84.
step-by-step explanation:∠c= 180-(90+30)
(so this is a standard 30 60 90 triangle, it if you have a drawing)ac=817cmyou'd have to use the angles since you don't have up to 2 sidesusing sin:
you're trying to find bc so it has to be either the opp or hyp. you know it's not hyp because you're already given that. the angle opposite bc is 30. that's how you know your angle's 30 and not 60
sin 30= bc/817
=408.5 cmusing cos:
same here. hyp is given so adj has to be bc. the angle adjacent to bc is 60 so 60 is the angle here and not 30.
bc= 817 cos 60 (adj=cos×hyp)
sorry im not sure if this is right sorry if i am wrong
answer: reflected about y axis and vertically up by 4 .
f(x) = x
for -f(x) it becomes -f(x) = -x ) [ multiplying by -1 both sides ]
to find -f(x) +4 ,we add 4 both sides of equation (1) ,we get
-f(x) +4 = -x +4 (2)
therefore on applying two transformation [ first reflection about y axis and translated 4 units upwards makes the function -x+4
