Option 1: Product. 250 is being multiplied by (1 + 0.018/2)^2t
Option 2: Sum. 1 is being added to 0.018/2
Option 3: Compounding periods. If it was just years, the exponent would be t not 2t.
Hope this helps!
Answer:
1/2(bh)
A=20
Step-by-step explanation:
The word "sum" means addition, so the question is asking you to add 914 and 878.
First you can add the hundreds, so 900 + 800 = 1,700
Then you can add the tens, so 10 + 70 = 80
And finally the units, so 4 + 8 = 12
When you add up all of these, you get your final answer as 1,792.
I hope this helps!
Answer:
A = 33.33
Step-by-step explanation:
P = 0.006A^2 - 0.02A + 120
*** P = 126 ***
126 = 0.006A^2 - 0.02A + 120
126 = (3/500)A^2 - (1/50)A + 120
*** multiplied with 500 on both sides ***
63000 = 3A^2 - 10A + 60000
63000 - 3A^2 + 10A - 60000 = 0
3000 - 3A^2 + 10A = 0
3A^2 - 10A - 3000 = 0
3A^2 + 90A - 100A - 3000 = 0
3A(A + 30) - 100(A + 30) = 0
(A + 30)(3A - 100) = 0
A + 30 = 0 | 3A - 100 = 0
A = -30 | 3A = 100
A = -30 | A = 100/3
Human age cannot be negative so
A = 100/3 = 33.33
Answer:
The ratio between the radii of circles A and B is equal to 
and this ratio represent the scale factor
Step-by-step explanation:
Let
x -----> the radius of circle A
y -----> the radius of circle B
z -----> the ratio between the radii of circles A and B
so
we know that
----> radius of circle A
----> radius of circle B
Find the ratio z
The ratio represent the scale factor of the dilation of radius of circle B to obtain the radius of circle A
Circles A and B are similar, because A translation, followed by a dilation will map one circle onto the other
