Answer: 2 1/4
Step-by-step explanation:
Convert both to same denominators and mixed numbers
1 1/2 = 1 2/4 = 6/4
3/4 = 3/4
3/4*6/4 = 18/16
Simplify: 9/4 = 2 1/4
the answer is 11/7 feet because the perimeter of a circle is πr² and a semi circle is half of a circle then the formula would be 1/2 πr² 1/2×22/7×1 (it is 1 because we have divided the diameter to get radius so we derived at 11/7.
Answer:
The value of x and y is ,
x = and y = 2
Step-by-step explanation:
The given two linear equation can be written as ,
y + 9x = -13 ....1 and
y - 3x = 7 .....2
Put the value of y from eq 1 into eq 2
i.e (-13 -9x) - 3x = 7
or, -12x = 7 +13
Or, -12x = 20
i.e X =
Now put t his value of x in any above two linear equation
Let put this value on eq 2 to get value of y
so its can be writen as.
y = 3x + 7
or, y = 3() + 7
or, y = -5 +7
i.e Y = 2
Hence the value of x and y is , x = and y = 2 Answer
For x = 10, f(x) = f(10) = 0.01(2)^10 = 10.24
For x =
17, f(x) = f(17) = 0.01(2)^17 = 1310.72
Now using
formula for the calculation of average rate of change of f(x).
(f(b) –
f(a)) / b – a = (f(17) – f(10)) / 17 – 10 = (1310.72 -10.24) / 7 = 185.78
