А support wire 12 yards long is attached to the top of a utility pole 10
stira [4]

Answer:

6.6 yd

Step-by-step explanation:

a^{2}+b^{2}=c^{2}

10^{2}+b^{2}=12^{2}        Substitute a= 10 and c=12

100+b^{2}=144      Evaluate the Powers

b^{2}=44               Subtract 100 on both sides.

b=\sqrt{44}             Square root both sides b>0 so you dont need ⊥

b=6.6              Use a calculator to evaluate.

Solve each of the quadratic equations.
lozanna [386]

The solution of the quadratic equation is x = 0 or x = 6 ⇒ 4th answer

Step-by-step explanation:

The form of the quadratic equation is ax² + bx + c = 0, where

  • a is the coefficient of x²
  • b is the coefficient of x
  • c is the numerical term

The quadratic equations has two roots, to find them factorize it into two factors and equate each factor by zero

∵ 3x = 0.5 x²

- Subtract 3x from both sides

∴ 0 = 0.5x² - 3x

- Multiply both sides by 2 to make the coefficient of x² integer

∴ 0 = x² - 6x

- Switch the two sides

∴ x² - 6x = 0

- Factorize it by taking x as a common factor

∴ x(x - 6) = 0

- Equate each factor by 0

∴ x = 0 → 1st root

∴ x - 6 = 0

- Add 6 to both sides

∴ x = 6 → 2nd root

∴ The roots of the equation are 0 or 6

The solution of the quadratic equation is x = 0 or x = 6

Lisa paid $42.37 for 15.3 gallons of gasoline. What was the cost per gallon, rounded to the nearest hundredth?
Sergio [31]

The answer is $2.80.

Step by step explanation:

42.37/15.3

15.3 divided by 15.3= 1

And you have to do the same for the numerator which is 42.37, so

42.37 divided by 15.3=2.76 (please check the calculator)

You would now have to round it which would be 2.80 (I think)

I hope it helps:) ❤️

Have a good day
