Mathematics
1 answer:
IRISSAK [1]3 years ago
7 0

Step-by-step explanation:

let

(-7,-8) =(x1, y1)

and (-6,7)=(x2, y2)

by the formula

d=√(y2-y1) ²+(x2-x1) ²

=√(7+8)²+(-6+7)²

=√15²+1²

= √225+1

= √226

How do you decide what numbers to use as the numerator and the denominator in each equivalent fraction to the given decimal?
Ratling [72]

Answer:

<em><u>For denominator the number of digits after the decimal are counted to find the multiple of 10s. </u></em>

<em><u>The numerator is the decimal number digits with the decimal removed.</u></em>

Step-by-step explanation:

The given number of the decimal is used as the numerator and the denominator of the decimal always has to be 10 or a multiple of 10 depending on the position of the decimal point.

For example if we have a number 4.3

The numerator will be 43( the decimal is removed) and the denominator will be 10 because in the original decimal number 4.3 the decimal was before only 1 number that is 3.

Now take the example of 4.36

The numerator will be 436 ( the decimal is removed) and the denominator will be 100 ( 10 *10 = 100) because in the original decimal number 4.3 the decimal was before 2 number that is 3 and 6.

so the fraction will be 436/100

Now if we divide 436 by 100 we will get the same answer as the original number

100√436         4.36

        <u>400 </u>

          360

          <u>300</u>

            600

        <u>   600</u>

          <u>xxx    </u>

The same process is applied to bigger numbers such as 4.365 and so on.

If we have a number 43.6 the numerator will be 436 ( the decimal is removed) and the denominator will be 10 because in the original decimal number 43.6 the decimal was before 1 number that is 6.

so the fraction will be 436/10

If we have a number 436.5  the numerator will be 4365 ( the decimal is removed) and the denominator will be 10 because in the original decimal number 436.5 the decimal was before 1 number that is 5.

so the fraction will be 4365/10

<em><u>For denominator the number of digits after the decimal are counted to find the multiple of 10s. </u></em>

<em><u>The numerator is the decimal number digits with the decimal removed.</u></em>

The concentration, in parts per million, of a type of antibiotic in a human's bloodstream after h hours can be modeled by the po
saveliy_v [14]

Answer:

C(3)=17.69\ ppm

Step-by-step explanation:

Given:

Given polynomial function is.

C(h)=-0.09h^{2} +3.5h+8

Hours  h=3

We need to find the concentration of the antibiotic after 3 hours.

Solution:

Rewrite the given polynomial function as.

C(h)=-0.09h^{2} +3.5h+8

Substitute  h=3 in given polynomial function.

C(3)=-0.09(3)^{2} +3.5\times 3+8

C(3)=-0.09\times 9+10.5+8

C(3)=-0.81+10.5+8

C(3)=-0.81+18.5

C(3)=17.69\ ppm

Therefore, the concentration of the antibiotic after 3 hours C(3)=17.69\ ppm .
