Answer:
Step-by-step explanation:
The values of the number is 43
x+21=64
subtract 21 on each side
x = 43
6x54= 324
6x50=300
6x4=24
300+24=324
The previous nearest cube root is 216 and the next cube root would be 343.
p/q could be any prime number which there are a lot of.
im going to say p is 1 and q is 3
next you would divide 1 by 3
1/3=0.666666667
324x0.666666667=216 exact
Answer:
y = -2x^2 - 4x - 1
Step-by-step explanation:
We can see that the graph passes through (-2, -1), (-1, 1) and (0, -1).
Let's solve
ax^2 + bx + c = y
a(-2)^2 + b(-2) + c = -1
4a - 2b + c = -1
a(-1)^2 + b(-1) + c = 1
a - b + c = 1
a0^2 + b0 + c = -1
c = -1
we got c = -1 so we input it into the other 2
4a - 2b - 1 = -1
4a - 2b = 0
2a - b = 0
2a = b
a - b - 1 = 1
a - b = 2
a = b + 2
Let's input b = 2a
a = 2a + 2
-a = 2
a = -2
b = 2a = 2*(-2) = -4
c = -1
y = -2x^2 - 4x - 1
Answer:
Find the complete table in attached file.
Step-by-step explanation:
Find the Incomplete table in attached file
Given:
A car travels 55 miles per hour for 2 hours.
So the speed of the car 55 miles per hour is constant for 2 hours.
Using speed formula.
Second row.
From the second row of the table 
and speed is constant 
, so we need to find only distance.
Third row.
From the third row of the table 
and speed is constant , so we need to find only distance.
Fourth row.
From the fourth row of the table 
and speed is constant , so we need to find time.
Therefore we complete the table from the above calculation.
