Estimate the Value Of Each Expression to the nearest integer .
omeli [17]

Answer:

see below

Step-by-step explanation:

14. We can represent 1 as √1 and 2 as √4 and because 1 < 3 < 4, we know that √3 is in between 1 and 2. However, 3 is closer to 4 than it is to 1 so √3 is about 2.

15. Again, 3 is √9 and 4 is √16. 9 < 10 < 16 so √10 is in between 3 and 4, however, since 10 is closer to 9 as it is to 16, we know that √10 is about 3.

16. -4 = -√16 and -5 = -√25, since 16 < 22 < 25, we know that -√22 is in between -4 and -5 but 22 is closer to 25 so the answer is -5.

17. -10 = -√100 and -11 = -√121 so -√120 is in between -10 and -11. Since 120 is closer to 121, the answer is -11.

Write the equation 0.3x2 + 5x - 7 =0 in general form and then choose the value of "b."
Musya8 [376]

For this case we have that by definition, an equation of the second degree is given by:

ax ^ 2 + bx + c = 0

We have the following equation:

0.3x ^ 2 + 5x-7 = 0

Then, according to the definition above, we have to:

a = 0.3\\b = 5\\c = -7

Thus, b equals 5.

Answer:

b = 5
