What is the slope of this line? (The answer should be a decimal.)
Airida [17]

Answer:

10/3 = 3.3333333...

Step-by-step explanation:

Point A -> (x₁,y₁) -> (0,1)

Point B -> (x₂,y₂) -> (3,11)

Slope -> (y₂-y₁)/(x₂-x1) -> (11-1)/(3-0) -> 10/3 -> 3.3333

Therefore, the slope of the line is 3.3 repeating

HELP. Write key ideas or a short summary about algebraic notation.
kramer

Answer:

Coefficients

In Algebra we work with Variable, Symbols or Letters whose value is unknown to us.

Algebraic Expression

In the above expression (i.e. 5x – 3),

x is a variable, whose value is unknown to us which can take any value.

5 is known as the coefficient of x, as it is a constant value used with the variable term and is well defined.

3 is the constant value term which has a definite value.

The whole expression is known to be the Binomial term, as it has two unlikely terms.

Find the length of side BC.<br> Give your answer to 3 significant figures.
Ksju [112]

Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = \frac{adjacent}{hypotenuse} = \frac{AB}{BC} = \frac{6.3}{BC} ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = \frac{6.3}{cos71} ≈ 19.4 cm ( to 3 significant figures )
