Answer:
13 x 1 = 13
Step-by-step explanation:
With the area on a shape you would take the width and multiply it by the length. Also anything times 1 is its self
Answer:
![A:E:M = 6:4:5](https://tex.z-dn.net/?f=A%3AE%3AM%20%3D%206%3A4%3A5)
Step-by-step explanation:
Given
Abam =N3.00 when Emeka = N2.00
Emeka = N4.00 when Madu = N5.00
Required
Determine their ratios
Represent their ratios with the first letter of their names:
From the first statement
---- (1)
From the second
----- (2)
Multiply the ratio in (1) by 2
![A:E = 3 * 2: 2 * 2](https://tex.z-dn.net/?f=A%3AE%20%3D%203%20%2A%202%3A%202%20%2A%202)
---- (3)
Notice that the value of E in both cases is the same i.e E = 4
(1) and (3) can be merged to give:
![A:E:M = 6:4:5](https://tex.z-dn.net/?f=A%3AE%3AM%20%3D%206%3A4%3A5)
Given:
The exponential function is
![y=2200(1.074)^x](https://tex.z-dn.net/?f=y%3D2200%281.074%29%5Ex)
To find:
The percentage rate of increase or decrease.
Solution:
The general form of an exponential function is
...(i)
Where, a is the initial value, r<0 is the rate of decrease, r>0 rate of increase, x is time period.
We have,
![y=2200(1.074)^x](https://tex.z-dn.net/?f=y%3D2200%281.074%29%5Ex)
It can be written as
...(ii)
On comparing (i) and (ii), we get
![r=0.074](https://tex.z-dn.net/?f=r%3D0.074)
r>0, so the it is the rate of increase. Multiply it by 100 to get the percentage rate of increase.
![r=0.074\times 100\%](https://tex.z-dn.net/?f=r%3D0.074%5Ctimes%20100%5C%25)
![r=7.4\%](https://tex.z-dn.net/?f=r%3D7.4%5C%25)
Therefore, the percentage rate of increase is 7.4%.
Answer:
Choice B
Step-by-step explanation:
Analysing both rhe graph and the table, we can see the functions f and g have a common point of (1,0), the x-intercept and same behaviour of reaching certain point of f or g, when the value of x gets closer to infinity.
This is matching the answer choice of B.
