Answer:
Step-by-step explanation:
let polynomial P(x)=ax³+bx²+cx+d
-3=-a+b-c+d
-2=d
-1=a+b+c+d
-1=a+b+c-2
a+b+c=1
-3=-a+b-c-2
a-b+c=1
a+b+c-(a-b+c)=1-1=0
2b=0
b=0
so a+c=1
6=8a+4b+2c+d
6=8a+4b+2c-2
8a+4b+2c=8
4a+2b+c=4
or 4a+0+c=4
4a+c=4
a+c=1
subtract
3a=3
a=1
1+c=1
c=0
reqd .P(x)=1x³-2=x³-2
Answer:
t + 8° > 82°
Step-by-step explanation:
Given that :
Let t = temperature when Susanne checks at 11:00
If t rises by 8 more degrees, it will break the record high temperature for that day
Record high temperature for the day = 82 degree
Hence,
Temperature at 11:00 + 8° > record high temperature for the day
t + 8° > 82°
Answer:
y=3 x=4
Step-by-step explanation:
4x - 2y = 10
<u>4x + y = 19</u>
-3y=-9
the 4x canceled out.
y=3
plug in y into one of the equations
4x + 3 = 19
4x=16
x=4
Hope this helps!
If not, I am sorry.
no this relation is not a function, because for each input (x), there is no output (y)
S = ut + (1/2)a(t²) Subtract ut from both sides
(1/2)a(t²) = S - ut Multiply both sides by 2
a(t²) = 2s - 2ut Divide both sides by t²
a= 2s/t² - 2u/t
a= (2S - 2ut)/t²
Answer is C) but there should be parentheses around the term (2S-2ut)
