Step-by-step explanation:
angle MRP
angle PRS=angle RPN (alternate angles)
2x+x+x+78°=180°(sum of angles of a triangle)
4x+78°=180°
4x=180°-78°
4x=102°
4x/4=102°/4
x=25.5
Answer:
f(x) = 0.4·3^x
Step-by-step explanation:
Exponential growth occurs when the base is greater than 1 and the exponent is an increasing non-negative function of the variable, or when the problem can be cast in that form using the rules of exponents.
Here, in f(x) = 0.4×3^x, the base is 3 (greater than 1), and the exponent of x has a positive coefficient.

Answer:
The theoretical probability is 1/18
Step-by-step explanation:
Firstly, we need to know the total number of possible results
By rolling two cubes, there are a total of 36 possible results
Now, the sum of 3 can be gotten by the addition of 1 to 2 or 2 to 1
If we have 1 on the first cube and 2 on the second, we have the correct sum
we can also have 2 on the first cube and 1 on the second
This gives a total of 2 possible ways of getting 3
The probability can be calculated by dividing the number of ways to get 3 by the total number of possible results
we have this simply as 2/36 = 1/18
Answer:
x = 6
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, thus
6x - 15 = x + 15 ( subtract x from both sides )
5x - 15 = 15 ( add 15 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
