we know that
The x-intercept is the value of the variable x when the value of the function is equal to zero
so
In the table we have
is a x-intercept, because
For
the value of the function is equal to zero
is a x-intercept, because
For
the value of the function is equal to zero
therefore
<u>the answer is</u>
the continuous function in the table has two x-intercepts
![(-1, 0)](https://tex.z-dn.net/?f=%28-1%2C%200%29)
![(-6, 0)](https://tex.z-dn.net/?f=%28-6%2C%200%29)
Answer:
The percentage decrease is 29%
Step-by-step explanation:
Given
![Initial = 300](https://tex.z-dn.net/?f=Initial%20%3D%20300)
![Final = 213](https://tex.z-dn.net/?f=Final%20%3D%20213)
Required
Determine the percentage decrease
This is calculated as thus:
![\%Percentage = \frac{|Final - Initial |}{Initial} * 100\%](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%20%5Cfrac%7B%7CFinal%20-%20Initial%20%7C%7D%7BInitial%7D%20%2A%20100%5C%25)
Substitute values for Final and Initial
![\%Percentage = \frac{|213 - 300|}{300} * 100\%](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%20%5Cfrac%7B%7C213%20-%20300%7C%7D%7B300%7D%20%2A%20100%5C%25)
![\%Percentage = \frac{|-87|}{300} * 100\%](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%20%5Cfrac%7B%7C-87%7C%7D%7B300%7D%20%2A%20100%5C%25)
<em>Get absolute value of -87</em>
![\%Percentage = \frac{87}{300} * 100\%](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%20%5Cfrac%7B87%7D%7B300%7D%20%2A%20100%5C%25)
![\%Percentage = \frac{87* 100\%}{300}](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%20%5Cfrac%7B87%2A%20100%5C%25%7D%7B300%7D)
![\%Percentage = \frac{8700\%}{300}](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%20%5Cfrac%7B8700%5C%25%7D%7B300%7D)
![\%Percentage = 29\%](https://tex.z-dn.net/?f=%5C%25Percentage%20%3D%2029%5C%25)
Hence, the percentage decrease is 29%
Answer:The value of the expression increases as r decreases.
Step-by-step explanation:
To find : What happens to the value of the expression as r decreases?
Given Expression: 80-2r
We check for different value of r as decreasing order,
r 80-2r
5 80-10=70
4 80-8=72
3 80-6=74
2 80-4=76
1 80-2=78
As r decreases the value of expression increases.
Therefore, the value of the expression increases as r decreases.
Hope this helps!
Answer:
Answer: C
Step-by-step explanation:
I think this the one becuase your supposed to find how tall the real pyramid itself, using the current convertion, And this proportion exactly shows the correct way to set up the eqaution.
arc length, s=(radius, r)(angle in radians, q)
q=tan^-1(s/r)
SO that saying the answer is 1.4 radians and the equation is probs q=7/5=1.4
