Answer: 0.907
Step-by-step explanation:
The average rate of change in a function from x= a to x = b is given by :-
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given: [tex]S(x)=573-133(0.987)^x[/tex]
Then, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year will be :
[tex]\dfrac{S(60)-S(40)}{60-40}=\dfrac{573-133(0.987)^{60}-573-133(0.987)^{40}}{20}\\\\=\dfrac{512.34-494.20}{20}\\\\=\dfrac{18.14}{20}\\\\=0.907[/tex]
Hence, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per yearr= 0.907

Which graph represents an exponential function?
Answer:
(You never showed the graphs we were suppose to choose from)
The graphs of all exponential functions have these characteristics. They all contain the point (0, 1), because a0 = 1. The x-axis is always an asymptote. They are decreasing if 0 < a < 1, and increasing if 1 < a.

form a triangle?
Answer:
No
Step-by-step explanation:
No, 5cm, 5cm, and 15cm cannot create a triangle because the side lengths do not follow the formula a + b > c. Since 5 + 5 = 10, and 10 is not greater than 15, these side lengths won't be able to form a triangle.

what is the probability of rolling a die and having it land on a factor of 30?
Using the probability concept, it is found that there is a 0.8333 = 83.33% probability of rolling a die and having it land on a factor of 30.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.In this problem, the outcomes are:
In total, there are 6 possible outcomes for the dice, which are the numbers from 1 to 6.Of those outcomes, 5 of them, 1, 2, 3, 5 and 6, are factors of 30, as the division of 30 by these numbers result in a remainder of 0.Hence:
[tex]p = \frac{5}{6} = 0.8333[/tex]
0.8333 = 83.33% probability of rolling a die and having it land on a factor of 30.

Simplify the expression (9.6x10-8) + (2x10-15). Express your answer in scientific notation.
Answer:
10.6^ -14
Step-by-step explanation:
The solution of the expression (9.6x10⁻⁸) + (2x10⁻¹⁵) is 9.6 x 10⁻⁸.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
The given expression will be solved as:-
E = (9.6x10⁻⁸) + (2x10⁻¹⁵)
First, multiply the numbers and convert them into decimal form now add both the numbers and again write in the scientific form.
E = 9.6 x 10⁻⁸.
Therefore, the solution of the expression (9.6x10⁻⁸) + (2x10⁻¹⁵) is 9.6 x 10⁻⁸.

What is the measure of angle b?
Answer:
44 degrees
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees!
You are given the two angles in the diagram, 46 and 90
Here's the equation I used to solve it!
180 = 46 + 90 + x
1. 180 = 136 + x
2. 180 - 136 = x
4. x = 44
