Answer:
The correct answer is three full teaspoons, assuming US measurements.
Step-by-step explanation:
15ml = 3.04326 teaspoons. To do this yourself, divide the volume value by 4.929
AnswerdV/dt = 4·pi·(40)2·(-2)
Step-by-step explanation:
Answer:
Only d) is false.
Step-by-step explanation:
Let
be the characteristic polynomial of B.
a) We use the rank-nullity theorem. First, note that 0 is an eigenvalue of algebraic multiplicity 1. The null space of B is equal to the eigenspace generated by 0. The dimension of this space is the geometric multiplicity of 0, which can't exceed the algebraic multiplicity. Then Nul(B)≤1. It can't happen that Nul(B)=0, because eigenspaces have positive dimension, therfore Nul(B)=1 and by the rank-nullity theorem, rank(B)=7-nul(B)=6 (B has size 7, see part e)
b) Remember that
. 0 is a root of p, so we have that
.
c) The matrix T must be a nxn matrix so that the product BTB is well defined. Therefore det(T) is defined and by part c) we have that det(BTB)=det(B)det(T)det(B)=0.
d) det(B)=0 by part c) so B is not invertible.
e) The degree of the characteristic polynomial p is equal to the size of the matrix B. Summing the multiplicities of each root, p has degree 7, therefore the size of B is n=7.
Answer:
It will be equal to 40
Step-by-step explanation:
We have to compute 
Let first find 3 !
For this we have to use factorial concept
So 3! will be equal to 3! = 3×2×1 = 6
Now According to 6+2 = 8
And now after solving bracket we have to multiply with 5
So 5×8 = 40
So after computation 
So the final answer will be 40
Answer:
Worked 40 hrs in week
Pay $300 for week
Step-by-step explanation:
Hours: 7-11a.m = 4
12-4p.m = 4 So, 4+4=8 hrs per day
So, 8 hrs per day × 5 days a week (8×5)=40
Worked 40 hrs in week
Pay: $7.50/hr So, $7.50×40 hrs (7.50×40)=300
So, $300 pay for week
