Find the perimeter of the triangle with vertices. Round your answer to the nearest tenth. A(-2, 5) B(3, 8) C(7, -4)

Answers

Answer:

perimeter = √34 + √160 + √162

perimeter ≈ 31.21

Step-by-step explanation:

AB = √[(3 + 2)² + (8 - 5)²] = √34

BC = √[(7 - 3)² + (-4 - 8)²] = √160

AC = √[(7 + 2)² + (-4 - 5)²] = √162

perimeter = √34 + √160 + √162

perimeter ≈ 31.21

Solve the system of linear equations below.2x + 5y = 34
x + 2y = 14

x = -26, y = 20

x = 2, y = 6

x = 3, y = 5.5

x = 10, y = 2

Answers

Answer:

Option (b) is correct.

x = 2 and y = 6 is the solution to the given system of linear equation.

Step-by-step explanation:

Given: The system of linear equation

2x + 5y = 34

x + 2y = 14

We have to solve the given system of linear equations.

Consider the given system of linear equation

2x + 5y = 34 .....(1)

x + 2y = 14 .......(2)

We solve the syatem using elimination method,

Multiply equation (2) by 2, we get,

(2) ⇒ 2x + 4y = 28 .....(3)

Subtract equation (1) and (3) , we have,

2x + 5y - (2x + 4y) = 34 - 28

Simplify, we get,

y = 6

And put y = 6 in (2), we get,

x + 2(6) = 14

x = 14 - 12

x = 2

Thus, x = 2 and y = 6 is the solution to the given system of linear equation.

moving company a charges 45$ on arrival and $25 an hour. The final bill was $470. How many hours did the movers work?

Answers

17 hours because if it's $25 an hour then you multiply 17 times 25 and you get 425 then you add the arrival money which is $45 then you get $470 :)

Alexander went to the store to buy some walnuts. The price per pound of the walnuts is $8 per pound and he has a coupon for $1 off the final amount. With the coupon, how much would Alexander have to pay to buy 2 pounds of walnuts? Also, write an expression for the cost to buy pp pounds of walnuts, assuming at least one pound is purchased.

Answers

Final answer:

Alexander would have to pay $15 for 2 pounds of walnuts after using the coupon. The expression for the cost to buy p pounds of walnuts is (8 * p) - 1.

Explanation:

The price per pound of walnuts that Alexander is buying is $8. If he is buying 2 pounds, without the coupon he would have to pay 2 * $8 = $16. But since he has a $1 off coupon, he would have to pay $16 - $1 = $15.

To formulate an expression for the cost to buy p pounds of walnuts, we consider that each pound costs $8 and there is a $1 off from the total price. So for p pounds, the expression would be (8 * p) - 1.

Alexander would have to pay $15 to buy 2 pounds of walnuts with the coupon. The expression is cost = ($8/pound) x pp - $1.

What is a cost function?

The functional connection between cost and output is referred to as the cost function. It examines the cost behaviour at various output levels under the assumption of constant technology. An essential factor in determining how well a machine learning model performs for a certain dataset is the cost function. It determines and expresses as a single real number the difference between the projected value and expected value.

Given that, the price per pound of walnuts is $8.

2 pounds x $8/pound = $16

Alexander would get $1 off the final amount.

Thus,

$16 - $1 = $15

So Alexander would have to pay $15 to buy 2 pounds of walnuts with the coupon.

The expression for the cost can be written as:

cost = ($8/pound) x pp - $1

Hence, Alexander would have to pay $15 to buy 2 pounds of walnuts with the coupon. The expression is cost = ($8/pound) x pp - $1.
