Answer:
f(2) = 36
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = 6^2
An exponent of 2 means 6 is a factor two times.
f(2) = 6×6
f(2) = 36
Answer:
36
Step-by-step explanation:
To evaluate f(x) = 6^x at x = 2, substitute 2 for x:
f(2) = 6^2 = 36
The length of the rectangular field is two times its breadth. If the perimeter of the field is 300m, find the length and breadth.
Answer:
Youu can call the breadth x and then, as the length is two times the breadth, it would be 2x.
So now when we call x to the breadth and 2x to the length we can do an equation, as we know the sum of the four sides is 300 meters, so
2x + 2x + x + x = 300
6x = 300
x = 300/6 = 50
We know that the breadth is 50m, and, the length, which is twice the breadth, would be 100m in this exercise.
SO in this case, the breadth is 50 meters and the length is 100 meters..

A scuba diver dove 40 feet below the surface. He swam up 12 feet to see a unique fish. He followed the fish down 8 feet. Then he followed the fish up 27 feet. How far below the surface is the diver now?
Answer: 9 feet below the surface.
Step-by-step explanation:
The scuba diver starts 40 ft below the surface. We can represent the position of the scuba diver as:
Position = -40ft
Where the negative sign is because it is below the surface of the water, so
"He swam up 12 feet to see a unique fish."
Now we need to add 12ft
Then his new position is:
Position = -40ft + 12 ft = -28ft
"He followed the fish down 8 feet.
Now we need to subtract 8ft
His new position is:
Position = -28ft - 8 ft = -36 ft
"Then he followed the fish up 27 feet."
Now we add another 27 ft.
The final position will be:
Position = -36ft + 27ft = -9ft
Then the final position of the scuba diver is -9ft, that means that he is 9 feet below the surface.

Ann and bill shared £440 in the ratio 9:2 Ann gives bill some of her money Bill now has the same amount as ann
Answer:
Bill gave Ann £220
Step-by-step explanation:
plz mark brainliest :D
Ann shared £360 and Bill shared £80.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Ann and bill shared £440
Ratio = 9:2
Total is = 9+ 2= 11
So, Anna shred
= 9/11 x 440
= 360
and Bill shred
= 2/11 x 440
= 80

Step-by-step explanation:
An acting school claims that 71% of its graduates land major acting roles within one year of graduation. A random sample of 50 graduates was surveyed, and 30 of them had landed major roles within one year of graduation. Let p hat = the proportion of the sample who had landed major roles within one year of graduation.
The probability that 60% or fewer graduates land a major acting role within one year of graduating from this school is 0.043. Does this result provide convincing evidence against the school’s claim?
A. Yes, it is expected that at least 60 graduates from this school will land a major role within one year of graduation.
B. Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely (0.043 < 0.05).
C. No, the difference between the sample proportion and the parameter is 11%, which is greater than 5%.
D. No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely (0.043 < 0.05).
Answer:
B
Step-by-step explanation:
EDGE2021!! since the actual probability is smaller than .05, we have evidence against the acting school claiming that 71% of its graduates land major acting roles within one year of graduation.

which graph shows a system of equations that can be entered into a graphing calculator to solve 16.9x-3.2x+18
Answer:
36.08
Step-by-step explanation:
This my answer thanks
The equation that can be entered into a graphing calculator to solve 16.9x–2.3=3.2x+18 are y = 16.9x - 2.3 and y = 3.2x + 18 respectively. Option B is correct.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
The equation is
16.9x - 2.3 = 3.2x + 18
From options
y = 16.9x - 2.3 and y = 3.2x + 18
Hence, the equation that can be entered into a graphing calculator to solve 16.9x–2.3=3.2x+18 are y = 16.9x - 2.3 and y = 3.2x + 18 respectively.
