After Jeremy runs across the width of the building, he must run down a ramp to the next building. Use the following portion of the picture to set up a ratio. a. sin=70 =(4/x)
b. cos70 = (4/x)
c. cos 70 =(x/4)
d. sin 70 = (x/4)

is the correct answer.

Step-by-step explanation:

First of all, let us label the diagram as shown in the attached figure.

OR = 20'

QS = 16'

is the right angled triangle that we get.

From the given figure symmetry, we can clearly see that:

Side OP = OR - QS

OP = 20 - 16 = 4'

Now, let us use trigonometric identity of cosine in .

Let the distance of ramp, OQ = x'

So, the above ratio becomes:

So, the correct answer is:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
