In a function f(x):

set of all the values that x can take is called the domain of the function.

Set of all the values that f(x) (or y) can take is called the range of the function.

Range can have either finite or infinite number of values depending on the function its domain.

For example, f(x) = x^2
can have infinite number of values in range.

whereas :
f(x) = [x] , 0<x<10
where [x] is the greatest integer function,

has finite number of values in its range.

A, B &amp; C form a triangle where
andrew-mc [135]

Answer:

16.5mm to. 1 decimal place

Step-by-step explanation:

Please check attachment for diagrammatic representation of the triangle.

Since one of the angles of the triangle is 90, this means that we are dealing with a right angled triangle

To find the length of AC, we make use of pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the other two sides. The hypotenuse is the longest side of the triangle which we have as 17.88 mm

Mathematically therefore

17.8^2 = 6.6^2 + AC^2

AC^2 = 17.8^2 - 6.6^2

AC^2 = 283.28

AC = √(273.28)

AC = 16.53 mm

This is 16.5 to 1 decimal place

Verizon [17]

Answer:

Mrs. Cabrini has a total of 2 1/8 quarts of tomato sauce.

Step-by-step explanation:

Since Mrs. Cabrini needs 2 quarts of tomato sauce to make a large batch of her spaghetti sauce. she has 1 1/4 quarts of her own, and she borrows 1/2 quart from the neighbor across the hall and 3/8 quart from the neighbor next door, to determine how many quarts does she have in all of her own must perform the following calculation:

1/4 = 0.25

1/2 = 0.5

3/8 = 0.375

0.25 + 0.5 + 0.375 = X

1.125 = X

1 + 1,125 = 2,125

Therefore, Mrs. Cabrini has a total of 2 1/8 quarts of tomato sauce.

What is the area of the composite figure?
lana [24]

Hello! :)

\large\boxed{A = 32.5cm^{2}}

We can use the following area to solve for the area of the trapezoid pictured:

A = \frac{1}{2}(b_{1} + b_{2})h

Where:

h = height

b1 = bottom base

b2 = top base

Plug in the given values:

A = \frac{1}{2}(9 + 4)(5)

Simplify:

A = \frac{1}{2}(65)\\\\A = 32.5 cm^{2}
