The correct answer is B.
With negative numbers, the "smaller" the number looks the bigger it is.
-2 is greater than -4.
Positive numbers are greater than negative numbers so we have:
8 > -2 > -4
Answer:
35000
Step-by-step explanation:
Answer:
- f(t) = 100·1.845^(t/10)
- $1025.15
Step-by-step explanation:
(a) The given numbers can be put directly into the form ...
... f(t) = (initial value) · (ratio)^(t/(time to achieve that ratio))
Here, we have an intial value of $100, and a ratio of $184.50/$100 = 1.845. The time to achieve that multiplication is 10 years (1967 to 1977). So, the equation can be written ...
... f(t) = 100·1.845^(t/10)
(b) You want to find f(38).
... f(38) = 100·1.845^(38/10) = 100·1.845^3.8 ≈ 1025.15 . . . dollars
Answer:
Step-by-step explanation:
a) Set up the variables:
Let <u>x</u> represent the width; Then <u>2x</u> will represent the length.
b) What is the equation that represents the above situation?
<u>Use perimeter formula:</u>
As we set up w = x and l = 2x, and we know that the perimeter is 30 cm, we can build an equation by substituting the values we know or set up:
c) solve the equation
- 30 = 2( 2x + x)
- 30 = 2(3x)
- 30 = 6x
- x = 30/6
- x = 5
d) the length and width are?
- The width is 5 cm and the length is twice the width, 5*2 = 10 cm
