Answer:
4th option
Step-by-step explanation:
using the rule of logarithms
= nlogx
- 8 = - 2 ( add 8 to both sides )
= 6 ( take the log of both sides )
log = log6
7xlog3 = log6 ( divide both sides by 7log3 )
x = 
≈ 0.23 ( to the nearest hundredth )
Answer:
The practical domain for the function f(x) will be [0,5].
Step-by-step explanation:
A model rocket is launched from the ground and its height from the ground is given by f(x), t seconds after its launch.
It is given that the rocket reaches maximum height at t = 2.5 seconds and comes back to the ground after t = 5 seconds.
So, at t = 0 seconds, the rocket was at the ground and hence, t can not be negative and after t = 5 seconds the rocket comes back to the ground and hence, t can not be greater than 5 seconds.
Therefore, the practical domain for the function f(x) i.e. the values of t lies in the interval [0,5]. (Answer)
Both integers have negative values
Explanation
Let
x and y represents the number
so, the options are
a) Both integers have negative values Both integers
b) Both integers have positive values
c)One integer has a positive value, and one integer has a negative value
d)The values of the two integers are opposites
as the point C , the sign depends on the bigger number
for example
so, the answer is Both integers have negative values

Answer:
Find x;
tg 45º= x/7
x=7*tg45º
x=7*1=7
Answer= x=7
Find y;
Cos 45º=7/y
y=7/ Cos45º
y=7/(√2/2)=14/√2=14√2/2=7√2
Answer= 7√2≈9.9.
