Answer:
9r
Step-by-step explanation:
1.5r - 3r + 10.5r
10.5r + 1.5r = 12r
12r - 3r = 9r
Final Answer = 9r
Answer:
7 decimal digits
Step-by-step explanation:
Because it ws rounded up to 0.6289731
and the known digits after the decimal are 7 in numbers.
0.6290 ......4 decimal digits
0.62897..... 5 decimal digits
0.628973.... 6 decimal digits
0.628973 ..... 7 decimal digits
Answer:
Here we are given with the numbers 4 16 36 64 100
So in these kind of questions we have to find what common pattern is prevailing so in this one:
Subtracting every no from it's succeeding no gives a difference and those respective differences are forming pattern as follows:
16–4=12
36–16=20
64–36=28
100–64=36
So we have a new series 12 20 28 36 in this Subtracting every no from it's succeeding no gives a difference of 8 now in the latter series continues with the same pattern of difference of 8 and the series proceeds with next numbers 44 52 60 now these no gets added in the first original series as described as follows :
100+44=144
144+52=196
196+60=256
So the next 3 numbers are 144,196,256
We have been given Marley was asked to solve 
using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.
We are asked to determine whether Marley is correct or not.
We know when an equation is in form 
, we can use discriminant to check for the real solutions of equation.
If 
, then the equation will have two real solutions.
If 
, then the equation will have one real solution.
If 
, then the equation will have no real solutions.
Let us find discriminant.
Since 
, therefore, the equation will have no real solutions, so Marley is correct.
