Answer: to express very large or very small numbers.c

Step-by-step explanation:

Scientific notation or scientific form is a way of expressing numbers that are too large or too small to be appropriately written in decimal form.

It is expressed as the product of a decimal form of number [commonly between 1 and 10] and powers of ten.

Hence, the scientific notation used to express very large or very small numbers.

The perimeter of a playing field for a certain sport is 214 ft. The field is a rectangle, and the length is 41 ft longer than th
malfutka [58]

Step-by-step explanation:

Perimeter of a rectangle = 2(L+W)

L is the length of the rectangle:

W is the width of the rectangle.

Given

Perimeter = 214feet

If the length is 41 ft longer than the width, then L = 41+W

Substitute L = 41+W into the formula:

P = 2(L+W)

214 = 2(41+W+W)

214 = 2(41+2W)

214 = 82+4W

4W = 214-82

4W = 132

W = 132/4

W = 33 feet

Since L = 41+W

L = 41+33

L = 74 feet

Hence the dimension of the field is 74ft by 33ft

<em>The width of the playing field is 33feet</em>

How can you analyze the numerator and/or the denominator in a rational expression to locate the x-intercepts?
andre [41]

Answer:

x=0 for f(x)=\frac{P(x)}{Q(x)}, with Q(x) \neq 0.

Step-by-step explanation:

To obtain x-intercepts, we need to give certain value, specifically x=0.

However, in case of a rational function, we must make sure that x=0 doesn't makes the denominator null, beacuse in that case the function is undefined.

Therefore, for x-intercepts we must say

x=0 for f(x)=\frac{P(x)}{Q(x)}, with Q(x) \neq 0.
