Answer:
5
Step-by-step explanation:
3 times 3 times 3 times 3 times 3 = 243
243 is between 200 and 300
Answer:
10058
Step-by-step explanation:
The equation is of the form
y = ab^x
Where a is the initial value, y is the final amount and x is the time
y = 6000 b^x
7200 = 6000 b^6
Divide each side by 6000
7200/6000 = b^6
1.2 = b^6
Take the 6th root on each side
1.2 ^ 1/6 = b^6 ^ 1/6
1.030853321 = b
y = 6000 (1.030853321) ^ x
Let x = 17
y = 6000 (1.030853321) ^ 17
y=10057.68696
Rounding to the nearest whole number
y = 10058
Answer:
b
Step-by-step explanation:
you can see in the figure, the function decrease from -1 to +3
Answer:
2w + 3y - 1
Step-by-step explanation:
(2x+2)/y = 4w + 2
isolate x:
2x+2= y(4w + 2)
2x = y(4w + 2) - 2
x = y(2w + 1) - 1
x = 2wy + y - 1
x = 2w + 3y -1
Answer:
The area of circle with radius half of original circle is 7 π cm² .
Step-by-step explanation:
Given as :
The Area of original circle = 28 π square centimeter
Let The radius of original circle = R
Let The area of circle with radius half of original circle = A square centimeters
Let The radius of circle with radius half of original circle = R'
Now, According to question
∵ Area of original circle = π × radius²
So, 28 π cm² = π × R²
Or, R² = 
Or, R² = 28 cm²
∴ R =
cm
i.e R = 2
cm
So, The radius of original circle = R = 2
cm
<u>Again</u>
∵ The radius of circle with radius half of original circle = R'
So, R' = 
i.e R' = 
∴ R' =
cm
So, The area of circle with radius half of original circle = π × R'²
i.e A = π × R'²
Or, A = π ×(
) ²
or, A = π × 7
So, The area of circle with radius half of original circle = 7 π cm²
Hence The area of circle with radius half of original circle is 7 π cm² . Answer
