What is ​ BC ​ ? <br><br> Enter your answer in the box.<br><br> units
Vladimir79 [104]

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

The equation gives the speed at impact, V metres per second, of an object dropped from a height of h metres. SHOW WORK From what
devlian [24]

Answer:

h = 17.65 m

Step-by-step explanation:

The given equation gives the speed at impact :

v=\sqrt{2gh}

h is height form where the object is dropped

Put v = 18.6 m/s in the above equation.

h=\dfrac{v^2}{2g}\\\\h=\dfrac{(18.6)^2}{2\times 9.8}\\\\h=17.65\ m

So, the object must be dropped from a height of 17.65 m.

a farmer sells his corn for $230 a metric ton with a small surcharge of $25. his neighbor sells her corn for $230 a metric ton a
anyanavicka [17]

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
