Answer:

The length of the ramp is x = AC = 10.35 feet

Step-by-step explanation:

From the ΔABC

AC = x = length of ramp

BC = 10 feet

\theta = 15°

\cos 15 = \frac{BC}{AC}

\cos 15 = \frac{10}{x}

x = 10.35 feet

Therefore the length of the ramp is x = AC = 10.35 feet

Enter the number of complex zeros for the polynomial function in the box.
NikAS [45]
Since the equation has a degree of 5 then, it will definitely have 5 zeroes. Complex zeroes of the polynomial always come in pair such that even if there are five zeroes, the complex zeroes could only be either 2 or 4 or none. 

Hence, the answer to this item is none, 2 or 4.

Given a∥b , and c is not parallel to a or b, which statements must be true?
Vlad1618 [11]

Answer:

1. We have been given that a∥b , and c is neither parallel to a nor b.

Let us see which of our given options are correct.

A. m∠7 can not be equal to m∠11  as line c is not parallel to line a.

B. m∠5 can not be equal to m∠12 as line c is not parallel to line b.

C. By alternate interior angles m∠4=m∠5  as ∠4 is inside line a and ∠5 is inside line b. Both angles are on the opposite sides of transversal.  

D. Since we know that corresponding angles are congruent. We can see that ∠5 corresponds to ∠1, therefore, m∠1=m∠5.

Therefore, Option C and D are correct choices.

2. We have been given that  AB∥CD and m∠4=85°. We are asked to find measure of ∠5.

Since we know that same side interior angles are supplementary. In our figure we can see that  ∠4 and ∠5 are same side interior angles.

Therefore, measure of ∠5 will be 95 degrees.  

Step-by-step explanation:

1. is m∠4=m∠5 by the alternate interior angle theorem.

2. Angles 4 & 3 are supplementary angles or linear pair and so they have to equal 180 and 180 - 85= 95 3 & 5 are corresponding angles so 95 should be your answer.

What is the average (arithmetic mean) of the first 90 measurements in a certain list of 92 measurements? (1) the average of the
marishachu [46]
The sum of all the measurements is just the average times the number.

\bar x = \frac{1}{n} \sum_{i=1}^n x_i

\sum_{i=1}^n x_i = n \bar x

So if the average of all 92 is 7 the sum of those is 92 \times 7

The average of the last two is 7.2 so their sum is 2 \times 7.2

That means the sum of the first 90 is 92 \times 7 - 2 \times 7.2

so the average of the first 90 is

 \dfrac{92 \times 7 - 2 \times 7.2}{90} = 6.99556 cm
