Look at this formula showing the relationship between temperature degrees Celsius and temperature in degrees Fahrenheit C = 5/9 * (P - 32) Which of these equations represents the given formula written in terms of H = 9/5 * (C + 32) H = 9/5 * (C - 32) P = 9/5 * C + 32 F = 9/5 * C = 32

The equation which represents the given formula written in terms of P is  

P = 9/5 * C + 32

Step-by-step explanation:

Seems the question is: Which of these equations represents the given formula written in terms of P. If so, we will make P the subject of the given formula.

C = 5/9 * (P - 32)

This can be written as

Multiplying both sides by 9, we get

Now, divide both sides by 5, we get

This gives

Now, Add 32 to both sides of the equation

This becomes

Hence

That is,  P = 9/5 * C + 32

Hence, the equation which represents the given formula written in terms of P is  P = 9/5 * C + 32.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
