Answer:
49.3 feet
Step-by-step explanation:
Shadow lengths and object heights are considered to be proportional, so we have ...
tree height/(tree shadow) = Andrew's height/(Andrew's shadow)
height / (85 ft) = (5.8 ft)/(10 ft)
height = (85 ft)(5.8/10) = 49.3 ft
The tree is 49.3 feet tall.
Answer:
It is a factor.
Step-by-step explanation:
its definitely a factor
rule: put (x-2)=0
so x = 2
now put this 2 in the equation as x

which equals to 0, as a result its a factor
you can check the sum in the calculator by yourself
hope it helps.
Using the domain concept, the restrictions on the domain of (u.v)(x) are given by:
A. u(x) ≠ 0 and v(x) ≠ 2.
<h3>What is the domain of a data-set?</h3>
The domain of a data-set is the set that contains all possible input values for the data-set.
To calculate u(x) x v(x) = (u.v)(x), we calculate the values of u and v and then multiply them, hence the restrictions for each have to be considered, which means that statement A is correct.
Summarizing, u cannot be calculated at x = 0, v cannot be calculated at x = 2, hence uv cannot be calculated for either x = 0 and x = 2.
