Analyzing the given values and the given equation, we have the following:
A = $25,000
r = 0.11
t = 6
The equation has the form:
y = A (1-r)^t
Plugging in the given values into the equation,
y = $25,000 (1 - 0.11)^6
y = $25,000 (0.89)^6
Therefore, the answer is
A. y=25,000(.89)^6
Given:
f(x) = 4x² + 1
g(x) = x² - 5
Then
(f + g)(x) = 4x² + 1 + x² - 5
= 5x² - 4
Answer: 5x² - 4
Answer: c= $( 5 x 5.20)
Step-by-step explanation:
Given: Total people =5
Money paid by each person = $5.20
Total cost of the sundae = (Number of people ) x (Money paid by each person)
Total cost of sunday : c= 5 x ($5.20)
i.e.Total cost of sunday = $(5 x 5.20)
i.e.Total cost of sunday = $ 26
Hence, the required equation to represent the total cost (c) of the sundae:
c= $( 5 x 5.20)
Answer: 1
Step-by-step explanation:
Bc 1 is match of P
The magnification is 0.54
Given,
The distance between object and concave lens, u = -21 cm
Focal length of the concave lens, f = -25 cm
Let m be the magnification.
m = v/u
Here v is the position of image.
We have to find v first.
By using lens equation we can determine v.
That is,
1/f = 1/v – 1/u
So,
- (1/25) = 1/v – (-1/21)
- (1/25) = 1/v + 1/21
1/v = - (1/25) – 1/21
1/v = (-25 – 21) / (21 x 25)
1/v = - (46/525)
Therefore v = - (525/46)
v = -11.41 cm
Now we have to find magnification, m.
m = v/u
= (-11.41) / (-21)
= 0.54
Here magnification is 0.54
