Answer:
0, 2
Step-by-step explanation:
Let's start by factoring an x² out
we have
x²( -x³+8)=0
we can easily see that x=0 is an answer
next we have
-x³+8=0
Solve for x and get 2

Answer:
108
Step-by-step explanation:
I believe its 108 because the angle above it is alternate exterior angles with bmd so its 72. And we know that the angle across it must be congruent as well. Straight line adds up to 180 so 180-72 is 108

The slope of the linear model is 1.5. What does this
mean in terms of the maximum noise level and the
number of people?
Answer:
Noise level increase by 1.5 per unit increase in number of persons
Step-by-step explanation:
The slope, m of a linear model is the value which represents the unit change in the dependent variable due to a unit chahe in the independent dependent.
The maximum noise in decibel is the dependent variable while the number of persons is the independent variable. Hence, the Coefficient of the independent vatiabkw is the slope and gives the rate of change in the dependent variable per unit Change in the independent variable.

Answer:
3√3
Step-by-step explanation:
Below I have attached the template on how to solve 30-60-90 triangles
We see that the hyptonouse has a length equal to 2x which means that
2x= 6√3
x= 3√3
We then see (from the template) that the lenght opposite to the 30 degree angle is equal to x and therefore our answer is just 3√3

A city's population has increased 40% in the last 5 years and is now 53,782 people.
What was the population 5 years ago?
Given:
A city's population has increased 40% in the last 5 years and is now 53,782 people.
To find:
The population 5 years ago.
Solution:
Let x be the population 5 years ago.
A city's population has increased 40% in the last 5 years.
So, present population is
[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]
It is given that the present population is 53782.
[tex]1.4x=53782[/tex]
[tex]x=\dfrac{53782}{1.4}[/tex]
[tex]x=38415.7142857[/tex]
[tex]x\approx 38416[/tex]
Therefore, the population 5 years ago was about 38416.

A train travels a total of 42 km at a constant speed of 85 km/h.
How long is its journey? Give your answer in minutes and seconds, to the nearest seconds
Answer:
formula is speed equals distance/ time.
now, speed above is 85km/h and distance is 42km.
time therefore is 42/85 which is 0.494h
now, 0.494h× 60 minutes is 29.64minutes(which is your answer in minutes)
now,29.64minutes × 60secs is 1778.82 seconds to the nearest seconds is 1779 seconds( which is your answer in seconds)
The population of a small town was 10,800 in 2003. Since then, the population has
decreased at a rate of 2.5% each year. What is the population of the town in 2021?
Answer: 5940
Step-by-step explanation: I don't know if it's for sure right but here
First I knew 10,800 was 100% and I wanted to find 2.5%
So I did:
10,800 divided by 100 and I got 108 = 1%
Than you want to do
108 x 2.5 = 270 ( 2.5% )
After that you wanted to find out how much years apart so
2021 - 2003 = 18
Then
18 x 270 = 4,860
Last of all you have to do
10,800 - 4,860 = 5940
