What is the area of the trapezoid?

Mathematics
1 answer:
liberstina [14]3 years ago

Answer:

Second option.

Step-by-step explanation:

You can use the formula for calculate the area of a trapezoid. This is:

A_{(trapezoid)}=\frac{h}{2}(B+b)

Where "B" is the larger base, "b" is the minor base and "h" is the height.

You can identify in the figure that:

B=8units\\b=4units\\h=4units

Then you can substitute values into the formula, getting that the area of the trapezoid is:

A_{(trapezoid)}=\frac{4units}{2}(8units+4units)

 A_{(trapezoid)}=24units^2

True or false: an cubic function may have 3 irrational zeros
jolli1 [7]
<h3>Answer: True</h3>

The key word here is "may" meaning that we could easily have 3 rational roots as well. An example of a cubic having 3 irrational roots would be

(x-1)(x-2)(x-3) = x³ - 6x² + 11x - 6

This has the rational roots x = 1, x = 2, x = 3.

However, we could easily replace 1,2,3 with any irrational numbers we want. So that's why the statement "a cubic has three irrational roots" is sometimes true.

In some cases, a cubic may only have 1 real root and the other 2 roots are imaginary.

Answer: 3

Step-by-step explanation:

A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. We have to find PQ. TAking the difference we have 94-91= 3.

In 1999, there were 9860 Great Danes registered with the American Kennel Club. The number of registered Labrador Retrievers was
jekas [21]

Answer:

153,997 Labrador Retrievers

Step-by-step explanation:

Let's make an equation for this problem. We know that there were 9,860 Great Danes. The number of Labrador Retrievers was 6,997 more than 15 times the number of registered Great Danes. More than can be changed to a plus sign. 15 times the number of Great Danes is 15 times 9,860. The equation is now 15*9,860 + 6,997.

15*9,860 is 147,900

147,900 + 6,997 is 153,997.
