Answer:
√20 units.
Step-by-step explanation:
Please see attached photo for diagram.
The other leg of the triangle is x as shown in the attached photo.
Using the pythagoras theory, we can obtain the the value of x as follow:
x² = 4² + 2²
x² = 16 + 4
x² = 20
Take the square root of both side.
x = √20 units
Therefore, the value of the other leg x of the triangle is √20 units
Answer:
option-B
Step-by-step explanation:
We are given
At the start of the year, 15 chameleons were introduced into a zoo
so,
The population of chameleons is expected to grow at a rate of 41.42% every year
so, r=0.4142
and x represents the number of years since the chameleons were introduced into the zoo
now, we can set equation to find total population
and we get
now, we can plug values
Average rate of change between 2 years and 4 years:
we can use formula
now, we can plug values
Average rate of change between 4 years and 6 years:
we can use formula
now, we can plug values
Average rate of change between 6 years and 8 years:
we can use formula
now, we can plug values
now, we will check each options
option-A:
we can see that
So, this is FALSE
option-B:
So, this is TRUE
option-C:
This is FALSE
option-D:
we got
so, this is FALSE
First you write what the vectors are, then you subtract z from w by subtracting their corresponding values <-4-3,1-4>= <-7,-3>, then to get subtracting the next answer you subtract w from z which is <3--4,4-1> = <7,3>
