x = 89 - 78

4) 4√3i

Answers

We can change the negative sign into i instantly as sqrt-1 is i.

With this the problem simplifies to sqrt48*i.

Now sqrt48=sqrt4*sqrt4*sqrt3=2*2*sqrt3

So the final product is 4sqrt3*i=4isqrt3.

Nineteeen less than 6 times a number;

6x - 19

equals; 16 more than the number; this is 16 + x

Thus;

6x - 19 = 16 + x

6x-x = 16 + 19

If Xavier rolls a number cube 90 times, how many times can he expect it to land on a number greater than 4? *

Answers

Answer:

30

Step-by-step explanation:

There are 6 possible outcomes when rolling a number cube, and each outcome is equally likely.

What is probability?

Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event.

There are 6 possible outcomes when rolling a number cube, and each outcome is equally likely.

Since we are interested in the number of times the cube lands on a number greater than 4, we only need to consider the outcomes 5 and 6.

The probability of rolling a 5 or a 6 on one roll of the cube is 2/6, or 1/3. Therefore, we can expect Xavier to roll a number greater than 4 about 1/3 of the time.

To find out how many times he can expect it to happen in 90 rolls, we can multiply the probability by the number of trials:

Expected number of rolls with a number greater than 4 = (1/3) x 90 = 30

Therefore, Xavier can expect the cube to land on a number greater than 4 about 30 times out of 90 rolls.

If a bowling ball is dropped out of an airplane,
what will its speed (velocity) be after 3.4
seconds, assuming no air resistance? (Hint: Use
the equation v = 32t).

Answers

Answer: The velocity of the ball is 108.8 ft/s downwards.

Step-by-step explanation:

When the ball is dropped, the only force acting on the ball will be the gravitational force. Then the acceleration of the ball will be the gravitational acceleration, that is something like:

g = 32 ft/s^2

To get the velocity equation we need to integrate over time, to get:

v(t) = (32ft/s^2)*t + v0

where v0 is the initial velocity of the ball. (t = 0s is when the ball is dropped)

Because it is dropped, the initial velocity is equal to zero, then we get:

v(t) = (32ft/s^2)*t

Which is the same equation that we can see in the hint.

Now we want to find the velocity 3.4 seconds after the ball is dropped, then we just replace t by 3.4s, then we get:

v(3.4s) = (32ft/s^2)*3.4s = 108.8 ft/s

The velocity of the ball is 108.8 ft/s downwards.

1. first identify a trigonometric ratio that will make it possible to find the value of x.
Answer = X is opposite to the angle 69° and 11 is adjacent to the angle 69°

2. To find the unknown​ value, which trigonometric function should be​ used?
Answer = Tangent

3. Use the tangent ratio for TAN 69°.
Answer = TAN 69° = [tex]\frac{x}{11}[/tex]

4. Multiply both sides by 11.
TAN 69° = [tex]\frac{x}{11}[/tex]
Answer = 11 · TAN 69° = x

5. Simplify
11 · TAN 69° = x

Answer = 28.7 ≈ x < -- (Rounded to the nearest tenth)

I think I'm suppose to use a geometry calculator and input TAN then multiply(or divide I don't know), but I don't have one right now so I need to know if there's any way I could get the same answer with a regular calculator.
