Solve for t(advanced rational equations)

Answers

Answer 1

Answer: t² -7 + 12t⁻² = 0

Multiply each side by t² :

t⁴ -7t² + 12 = 0

This is a quadratic equation in the variable ' t² '.
For just a moment, to avoid confusion, let U = t².
Then the equation is

U² - 7U + 12 = 0
whence
(U - 4) (U - 3) = 0
and
U = 4 and U = 3 .

Now we can go back to ' t² ' in place of U :

t² = 4
t = +2 and t = -2

t² = 3
t = +√3 and t = -√3

Answer 2

Answer: $t^2-7+12t^(-2)=0\n t^4-7t^2+12=0\n t^4-3t^2-4t^2+12=0\n t^2(t^2-3)-4(t^2-3)=0\n (t^2-4)(t^2-3)=0\n (t-2)(t+2)(t^2-3)=0\n t=2 \vee t=-2 \vee t=-√(3)\vee t=\sqrt3$

Find the lateral area of the right prism with height 0.3 dm, if the base of the prism is: Parallelogram with sides of 6 cm and 20 mm

Answers

The lateral area of the parallelogram prism is 0.048 m²

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

0.3 dm = 0.3 m, 6 cm = 0.06 m, 20 mm = 0.02 m, hence:

The lateral area of the right prism is given by:

Lateral area = 2(0.06 * 0.3) + 2(0.02 * 0.3) = 0.048 m²

The lateral area of the parallelogram prism is 0.048 m²

Item 1 The value of a car is $23,000. It loses 11.1% of its value every year. Find the approximate monthly decrease in value. Round your answer to the nearest tenth.

Answers

Answer:

$212.8

Step-by-step explanation:

If the car loses 11.1% per year, we need to calculate how much money is that:

$23,000(11.1)/(100) = 2,553.$ ; this value is the lost per year.

Now, in order to calculate this loss per month, we divide it by 12:

$(2553)/(12) =212.75$

Hence, the monthly value decrease is $212.8, rounding it to the tenth.
