Answer:
y=x+11
Step-by-step explanation:
Plant grows at 3CM per day
equation: y= 3x
21 is y so 21= 3x. divide by 3 so it's been 7 days
Answer:

Step-by-step explanation:
The question to be solved is the following :
Suppose that a and b are any n-vectors. Show that we can always find a scalar γ so that (a − γb) ⊥ b, and that γ is unique if
. Recall that given two vectors a,b a⊥ b if and only if
where
is the dot product defined in
. Suposse that
. We want to find γ such that
. Given that the dot product can be distributed and that it is linear, the following equation is obtained

Recall that
are both real numbers, so by solving the value of γ, we get that

By construction, this γ is unique if
, since if there was a
such that
, then

Answer: 132
Step-by-step explanation:
Since we are informed that Group 1 of trees produced 25 percent more coconuts than Group 2 did and that Group 1 produced 165 coconuts, the number of coconuts that Group 2 produce will be:
= [100 / (100 + 25)] × 165
= 100/125 × 165
= 0.8 × 165
= 132
Group 2 produced 132 coconuts.
