Answer: 153

Step-by-step explanation:

area of rectangle= 16 x 3= 48

area of trapezium= 1/2(a+b)h

=1/2(16+5)x 10

=105

105+48= 153 in^2

Given a polynomial function f(x), describe the effects on the y-intercept, regions where the graph is increasing and decreasing,

erma4kov [3.2K]

The y-intercept of is .
Of course, it is 3 less than , the y-intercept of .
Subtracting 3 does not change either the regions where the graph is increasing and decreasing, or the end behavior. It just translates the graph 3 units down.
It does not matter is the function is odd or even.

is the mirror image of stretched along the y-direction.
The y-intercept, the value of for , iswhich is times the y-intercept of .Because of the negative factor/mirror-like graph, the intervals where increases are the intervals where decreases, and vice versa.
The end behavior is similarly reversed.
If then .
If then .
If then .
The same goes for the other end, as tends to .
All of the above applies equally to any function, polynomial or not, odd, even, or neither odd not even.
Of course, if polynomial functions are understood to have a non-zero degree, never happens for a polynomial function.

Use the coordinates to find the perimeter of the rectangle. D(1,2), E(1,7), F(4,7), G(4,2) *

JulsSmile [24]

Answer:

Step-by-step explanation:

DE is the vertical line x=1. It extends between y=2 and y=7, a distance of 5 units.

EF is the horizontal line y=7. It extends from x=1 to x=4, a distance of 3 units.

Then the perimeter of half the rectangle is 5+3 = 8 units.

The perimeter of the rectangle is 2·8 = 16 units.

What is the next number? 2+3=8 3+7=27 4+5=32 5+8=60 6+7=72 7+8=?

ale4655 [162]

Answer:

Step-by-step explanation:

2 + 3 = 8

8 : 2 = 4; 4 - 1 = 3 (subtract 1)

3 + 7 = 27

27 : 3 = 9, 9 - 2 = 7 (subtract 2)

4 + 5 = 32

32 : 4 = 8; 8 - 3 = 5 (subtract 3)

5 + 8 =60

60 : 5 = 12, 12 - 4 = 8 (subtract 4)

6 + 7 = 72

72 : 6 = 12, 12 - 5 = 7 (subtract 5)

7 + 8 = x

x : 7 = y, y - 6 = 8 (subtract 6)

Solve:

y - 6 = 8 add 6 to both sides

y - 6 + 6 = 8 + 6

y = 14

x : 7 = y ⇒ x : 7 = 14 ⇒ x = (14)(7) ⇒ x = 98

Below are two parallel lines with a third line intersecting them.

Ulleksa [173]

Answer:

x = 88

Step-by-step explanation:

These angles are same side exterior angles, and when the lines are parallel, same side exterior angles are supplementary

x + 92 =180

Subtract 92 from each side

x+92-92=180-92

x =88
