**Given:-** ; , where a is any positive real number.

**Consider the helix parabolic equation : **

now, take the derivatives we get;

**As, we know that two vectors are orthogonal if their dot product is zero**.

Here, are orthogonal i.e,

Therefore, we have ,

take t common in above equation we get,

⇒ or

**To find the solution for t;**

take

The number determined from the coefficients of the equation

The determinant

Since, for any positive value of a determinant is negative.

Therefore, there is **no solution.**

**The only solution, we have t=0.**

Hence, we have **only one points on the parabola ** i.e <1,0>

**Answer:**

Estimate angle of elevation = 15.4°

**Step-by-step explanation:**

**Given:**

Start elevation = 9,400 ft

Ends near the summit = 14,255 ft

horizontal distance = 17,625 ft

**Find:**

Estimate angle of elevation.

**Computation:**

⇒ Total elevation distance = Ends near the summit - Start elevation

⇒ Total elevation distance = 14,255 - 9,400

⇒ Total elevation distance = 4,855 ft

⇒ Tan A = 4,855 / 17,625

⇒ Tan A = 0.2754

⇒ Tan A = 15.4°

**Estimate angle of elevation = 15.4°**

**The height and length of the box to the nearest tenth will be 10.6 inch and 7.4 inch respectively.**

*Explanation*

Suppose, the height of the box is inch

As the length of the box is 3.2 in. less than the height, so the length will be:

Given that, the width of the box is 2.3 inch. and the volume is 180.4 inch³

__Formula for Volume of a box:__

So, the equation will be....

Now using quadratic formula......

(Negative value of is ignored as the height can't be negative)

**So, the height to the nearest tenth will be 10.6 inch and the length will be: **

**Answer:**

a) The probability that the chosen ball is blue is 56.84%

b) If the chosen ball is blue, there is a 35.19 probability that it came from the first urn.

**Step-by-step explanation:**

a) **What is the probability (as a %) that the chosen ball is blue? **

First the urn is chosen, then the ball. There can be a blue ball from urn 1 and from urn 2.

-The probability of a blue ball being chosen from urn 1 is:

40%(8 blue balls among 20 in urn 1, 8 of 20 is 40%) of 50%(the chance of urn 1 being chosen is 50%)

So

-The probability of a blue ball being chosen from urn 2 is:

73.68%(14 blue balls among 20 in urn 2, 14 of 19 is 73.68%) of 50%(the chance of urn 2 being chosen is 50%)

So

The probability that the chosen ball is blue is %.

**b) If the chosen ball is blue, what is the probability (as a %) that it came from the first urn?**

**This item can be formulated as the following problem:**

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

In this item, A(what has happened) is the ball being blue. In item a), we found that P(A) = 0.5684.

B is the blue ball coming from the first urn. P(B), the probability of the first urn being chosen, is 50% = 0.5.

P(A/B), the probability of the blue ball being chosen from the first urn is 40% = 0.4.

So:

If the chosen ball is blue, there is a 35.19 probability that it came from the first urn.
