If g(x)= x squared- x find the value of g(3b)

Mathematics
1 answer:
LuckyWell [14K]3 years ago
3 0

If:

g(x) = x^2-x

find g(3b). In this problem, you'd literally plug the 3b into the equation. Let's do that:

g(3b) = (3b)^2-3b

g(3b) = 9b^2-3b

We can further simplify this by pulling out a 3 and a "b":

g(3b) = 3b(3b-1)

So, your answer is g(3b) = 3b(b-1).

MAXImum [283]

Answer:

√36 = 6

a^2 + b^2 = c^2

6^2 + 6^2 = c^2

36 + 36 = c^2

72 = c^2

√72 = c

If A and B are independent events, P(A) = 0.25, and P(B) = 0.3, what is P(AB)?
Marrrta [24]

Answer:

P(A) = 0.25, P(B= 0.3

And if we want to find P(A \cap B) we can use this formula from the definition of independent events :

P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075

And the best option would be:

P(A \cap B) =0.075

Step-by-step explanation:

For this case we have the following events A and B and we also have the probabilities for each one given:

P(A) = 0.25, P(B= 0.3

And if we want to find P(A \cap B) we can use this formula from the definition of independent events :

P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075

And the best option would be:

P(A \cap B) =0.075

What is the slope of the line
cupoosta [38]

Answer:

I believe the slope would be -2

Step-by-step explanation:

The line goes <u>down 2</u> boxes and <u>over 1</u> box before it intersects with another point.  Knowing slope = \frac{rise}{run}, we know that slope = \frac{-2}{1} which is equal to -2.

if a tree 20 meters tall casts a shadow 30 meters long, what is the angle of elevation from the shadow to the tip of the tree, t
inn [45]

sketch the situation

a trigonometric function that is a relation between the angle of elevation and the 2 sides of the rectangles is the tan

\tan \theta=\frac{opp}{adj}\tan \theta=\frac{20}{30}=\frac{2}{3}

find the inverse

\begin{gathered} \tan ^{-1}(\frac{2}{3})=\theta \\ \theta=33.69º \end{gathered}

after rounding the angle of elevation is 34º.
