Answer:
BC = 25
Step-by-step explanation:
AB = AC since it is an isosceles triangle
4x+1 = 2x+23
subtract 2x from each side
4x-2x+1 = 2x-2x+23
2x +1 = 23
subtract 1 from each side
2x+1 -1 = 23-1
2x = 22
divide by 2
2x/2 =22/2
x =11
BC = 3x-8
BC = 3(11) -8
BC =33-8
BC = 25
Answer:
h = 17.65 m
Step-by-step explanation:
The given equation gives the speed at impact :

h is height form where the object is dropped
Put v = 18.6 m/s in the above equation.

So, the object must be dropped from a height of 17.65 m.
Step-by-step explanation:
Step one:
The farmer sells his corn for $230 a metric ton
small surcharge = $25.
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x+25--------------1
The neighbor sells her corn for $230 a metric ton
he gives $15 rebate------<em>A rebate is a partial refund of the cost of an item</em>
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x-15----------------2
Step two:
Equating the two equation above
230x+25=230x-15
230x-230x=25+15
0=40
The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost
