Answer:

f(x) = (x + 10)(x + 4)(x - 1)

Step-by-step explanation:

Given the zeros of a polynomial, say x = a and x = b, then

the factors are (x - a) and (x - b)

The polynomial is then the product of the factors

f(x) = (x - a)(x - b)

Here the zeros are x = - 10, x = - 4 and x = 1, thus the factors are

(x - (- 10)), (x - (- 4)) and (x - 1), that is

(x + 10), (x + 4) and (x - 1)

f(x) = (x + 10)(x + 4)(x - 1)

Estimate to the nearest integer.<br> 21<br> O 3<br> O 4<br> O 5
Rudiy27

Answer:

5

Step-by-step explanation:

So the square root of 21 is 4.582...

If you round 4.582.. it is 5

Because you look at the first number behind the decimal (tenths place) if it is 4-0 you leave the number the same. If it is 5-9 you increase the number by 1.

Hope this helps ya!!

Estimate the answer to 26.6 x 24.4/ 5.67 x 4.02.
NeTakaya
For this question, we must use BIDMAS

Brackets
Indices
Division
Multiplication
Addition
Subtraction

26.6  x  24.4  /  5.67  x 4.02

First, round all the values to their first significant figure

30 x 20 / 6 x 4

The first occurring operation in BIDMAS is Division
20/6 = 3 1/3

Now do the multiplication

30 x 3 1/3 x 4 = 400

Or you can round to the nearest whole number (although it can be more difficult if doing sums in your head)

27 x 24 / 6 x 4
27 x 4 x 4
27 x 16 = 432

The more accurately you round, the closer the estimation is to the actual answer (≈460)

1 Sig Fig = 400
Whole number = 432
