Just sub x in with 5.
So 6(5)^3+8(5) = 6 (125) + 40 = 750 + 40 = 790.
So 790
Answer:
1650 families
Step-by-step explanation:
In a survey of his neighborhood, Timothy found out that 3 families out of 7 have a dog for a pet.
The given ratio = 3:7
When written as a fraction = 3/7
The number of families that would have a pet dog in a town with about 3,850 families is given as:
3/7 × 3,850
= 1650 families
Therefore, 1650 families would have a pet dog in town.
We're given an inner product defined by
That is, we multiply the values of 
and 
at 
and add those products together.
The inner product is
To find the norms 
and 
, recall that the dot product of a vector with itself is equal to the square of that vector's norm:
So we have
Finally, the angle 
between 
and 
can be found using the relation
You can use a calculator and just root them
Answer:
x=2. or. x=8
Step-by-step explanation:
x^2-10x+16=0. s=-10
x^2-8x-2x+16=0. p=16
x(x-8)-2(x-8)=0. [-8,-2]
(x-2)(x-8)
x=2. or. x=8
