Answer: -1 and 1
Step-by-step explanation:
i gotchu, no worries!
first, move the constant to the right. then, you calculate that. then change the signs, and simplify the expression. (i can't type out square root signs, so thats why there's no work shown.)
then, evaluate it.
x^2 - 9 = -2^3
next, move the constant to the right.
x^2 - 9 = -8
next, calculate it.
x^2 = -8 + 9
simplify it.
x^2 = 1
finally separate the solutions.
x = 1
x = -1
Answer:
j(t)=600*1.09ᵗ⁻¹
Step-by-step explanation:
In 2014, there were 600 jobs.
The next year, the number is expected to grow by 9%.
Since the growth rate is a percentage, this is an example of a geometric sequence.
The nth term of a Geometric Progression is given as:
Uₙ=arⁿ⁻¹
In the first year, population =600
r=(100+9)%=1.09
Therefore the function j(t) that gives the expected number of jobs from the year 2014 is given as:
Uₙ=arⁿ⁻¹
j(t)=600*1.09ᵗ⁻¹ where t=1,2,3...
The value of t=1 is for the year 2014.
Answer:
1727 inches or approximately 143.91667 feet
Step-by-step explanation:
circumfrence is the so its . this gives you a circumfrence of 69.08 inches which is eaual to one revolution. you simply have to do inches. I didnt know if you also needed the answer in feet, so i divided that by 12 to get an approxamation of 143.91667 feet (it comes out with a repeating 6, so i rounded it to 7 on the third to six be accurate).
7.$56,8.-$17,500,9.$810,10.-45,11.$-45,12.-$1,368,13.$27,14.$8,848,15.$390,$209
the answer is 2) 10 degrees below zero.
If it's below zero then it is a -10.
