The function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3
<h3>How to determine the function that could be represented by Rebecca’s graph? </h3>
The properties are given as:
- The function is decreasing.
- The left end is approaching a constant.
For an exponential function to keep decreasing, one or more the following must be true:
- The rate is less than 1
- The leading factor is negative and the rate is greater than 1
For the left end of an exponential function to approach a constant, the following must be true:
- The leading factor is negative and the rate is greater than 1
The equation that has the above properties is f(x) =-2(5/4)^x+3
Hence, the function that could be represented by Rebecca’s graph is f(x) =-2(5/4)^x+3

Answer: $85.70
Step-by-step explanation:
So let's break this question down.
You need a bit of both, right? Well we need to calculate how many multiple choices we can do whilst having true/false questions, and not going over or under on points.
So, let's pick a random number, 5. So let's do 8x5, that equals 40.
ohmygoditsrightiwasseriouslyjustguessing
Ok so now we have our number, 5 multiple choice questions.
The true/false questions should be easy, just do 3x20 and you get 60.
ANSWER: 5
Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)
enot [183]
Answer:
<em>The area of the polygon CDEFGH is 7</em>
Step-by-step explanation:
<u>Area of a Polygon</u>
The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.
The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:
The area CDHE is a square of length side 2. Area of a square:
The area HEFG is a trapezoid with bases lengths 4 and 2, and height 1. Area of a trapezoid:
Calculate both areas:
Total Area=4+3=7
The area of the polygon CDEFGH is 7
Answer:
D. 24
Step-by-step explanation:
Angles are the same, so 84 = 3x.
To get x alone, you divide 3 by both sides.
84/3 = 24
24 = x.
