Answer:
nth term = 18 - 3n
Step-by-step explanation:
nth term = a + (n - 1)d
a1 = 15
d = -3
nth term = a + (n - 1)d
= 15 + (n - 1)-3
= 15 + (-3n + 3)
= 15 - 3n + 3
= 18 - 3n
nth term = 18 - 3n
For instance, if you want to find the 10th term
nth term = 18 - 3n
10th term = 18 - 3(10)
= 18 - 30
= -12
10th term = -12
Answer:
50 %
Step-by-step explanation:
From the diagram attached,
Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1
The number of students that like watching television and reading (WnR) = 70
The total number of students (μ) = 40+20+70+10
The total number of students (μ) = 140
Substitute these values into equation 1
Percentage of total students that like watching television = (70/140)×100
Percentage of total students that like watching television = 1/2(100)
Percentage of total students that like watching television = 50 %
Answer:
6
Step-by-step explanation:
Alright! So, this might seem complicated at first, but in the end its just a bit of algebra. If we think of a triangle, adding all of the sides together creates the perimeter. This means that 3(x-3) + 4x-1 + 2x+5 = 49. After this we can simplify to 9x - 5 = 49, and 9x = 54. Since 54/9 = 6, this means that x = 6.
It's letter A bc 4/9 is 0.444444444
Answer:
For x=1 substituting in f(x) the value of x
f(1)=-3(1)+1 = -2
For x=0 substituting in g(x) the value of x
g(0)=3^(0) =1
Finally, we have to find for what value of x the function f(x) gives -8
f(x) = -8
-8 = -3x+1
-3x=-9
x=3
