The question is related to trigonometry and we have to use the formula of double angle .
Here we use double angle formula of tangent function which is
Given expression is
Comparing it with double angle formula, we will get x = 5
SO the required expression is equal to
So the answer is tan(10) .
-3(3x-5y-9) that’s the factored expression
Answer:
Below
Step-by-step explanation:
You can use this formula to find the sum of an arithmetic series
Sn = n / 2 (a1 + an)
You need to find the number of terms in each series before using the formula
Tn = a + (n - 1) d
a) 53 = 5 + (n - 1) 3
n = 17
Sn = 17 / 2 (5 + 53)
= 493
b) 98 = 7 + (n - 1) 7
n = 14
Sn = 14 / 2 (7 + 98)
= 735
c) -102 = 8 + (n - 1) -5
n = 23
Sn = 23 / 2 (8 + (-102))
= - 1081
d) 41/3 = 2/3 + (n - 1) 1
n = 14
Sn = 14 / 2 (2/3 + 41/3)
= 301 / 3 or 100 1/3
Hope this helped! Best of luck <3
Answer:
Step-by-step explanation:
The given equation is :
We need to solve it using inverse operations.
Subtract 5 from both sides of the equation.
So, the solution of the given equation is .
Answer:
The last option
Step-by-step explanation:
It can't be 100 added to any, as that would make y greater than x when it is not. And, 35x and 3.5x would be too much.
y = 0.35x + 1.5
y = 0.35(100) +1.5
y = 35 + 1.5
y = 36.5
x = 100, y = 36.5 Which is the first set when x is not 0
