Answer:
S={( 1 )}
Step-by-step explanation:
-3x²+6x+1=4
-3x²+6x+1-4=0
-3x²+6x-3=0
∆=b²-4.a.c
∆=(6)²-4.(-3).(-3)
∆=36-36
∆=0
x'=x"=-b/2a=-(+6)/2.(-3)=-6/-6=1
Answer:
The rate of change in the function Y = 2X +5 is <u>greater than</u> the rate of change of the function represented in the table
Step-by-step explanation:
The given function is
![y = 2x + 5](https://tex.z-dn.net/?f=y%20%3D%202x%20%2B%205)
For a linear function in the form y=mx +c, the rate of change is <em>m</em>.
The rate of change of this function is 2
We now determine the rate of change of the function represented in the table.
This is given by
![\frac{change \: in \: y}{ change \: in \: x}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bchange%20%5C%3A%20in%20%5C%3A%20y%7D%7B%20change%20%5C%3A%20in%20%5C%3A%20x%7D%20)
Using the corresponding values from the table, the rate of change is
![\frac{6 - 4}{5 - 3} = \frac{2}{2} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%20-%204%7D%7B5%20-%203%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B2%7D%20%20%3D%201)
Therefore the rate of change in the function Y = 2X +5 is greater than the rate of change of the function represented in the table
According to the weather station, the temperature was –4 degrees Celsius last night. And today, it is now –10 degrees Celsius.
What was the change in temperature over night?
Answer: 6 degrees Celsius
Solution:
= -4 – (-10)
= -4 + 10
= 6 degrees Celsius
43/100 = 0.43
21/2/100 = 0.105
13.6/100 = 0.136
521/100 = 5.21
28 feet
32 feet divided by 8 equals 4
so the lake is in sections of 4
take 4 times it by 7
answer is 28 feet
to check your answer 28/32 simplified is 7/8
