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:
The trinomial
is not a perfect square trinomial because the third term is not a square.
Step-by-step explanation:
A trinomial is an expression composed of three terms that are joined together by addition or subtraction.
A perfect square is created when a value is multiplied times itself. Thus,
, making the trinomial a² + 2ab + b² a perfect square.
To show that a trinomial is a perfect square you must show that if the first and third terms are squares, figure out what they're squares of. Multiply those things, multiply that product by 2, and then compare your result with the original quadratic's middle term. If you've got a match (ignoring the sign), then you've got a perfect-square trinomial.
The trinomial
is not a perfect square trinomial because the third term is not a square.
Answer:
x=12 ADB= 56 BDC= 54
Step-by-step explanation:
ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation
(3x+10) + (4x-4) = 90
I combined like terms to give me 7x+6=90
Then I subtract 6 from both sides giving me 7x=84
Last I divide 7 on both sides. x=12
Then I input the x (12) into the equation and solve it from there
3(12)+10 and 4(12)-4
3(12)+10=56
4(12)-4=54
. . . I think. Hope this helps!
