If the temperature is 86∘f, what is it in celsius?
a. write the formula for temperature from your text:
b. solve that formula for c (hint: see example 3)
c. now use your new formula from b to find the temp in celsius if it is 86o f.

The answer to your question is: T = 30°C

Step-by-step explanation:

Data:

T = 86°F

T =   ? °C

a. Write the formula for Temperature from your text:

                        °C = (°F -32)/ 1.8

b. Solve that formula for C (hint: see example 3)

                        I don't know which is the example 3

c. Now use your new formula from b to find the temp in Celsius if it is

86o F.

                        °C = (86°F - 32) / 1.8         substitution

                              = 54/1.8                       simplifying

                              = 30                             result

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.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
