Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
On further simplification, we get
The distance from point C to D is 5 units. Therefore, the correct option is A.
Answer:
Part 1) The perimeter of the park is
Part 2) The area of the park is
Step-by-step explanation:
see the attached figure to better understand the problem
Part 1) Find the perimeter pf the park
we know that
The perimeter of the figure is the sum of its six length sides (see the figure)
so
Part 2) Find the area of the park
The area of the park is equal to the area of two rectangles
The area of rectangle is equal to
substitute the values
Answer:
x = -2
Step-by-step explanation:
If you factor out 1/9 you get rid of the fractions and that makes the equation a whole lot easier.
Next, eliminate the brackets:
Combine the terms:
Answer:
(- ∞ , 3) u (7 , ∞ )
Step-by-step explanation:
f(x) is negative below the x- axis
This is int the intervals x < 3 , x > 7
domain is (- ∞ , 3 ) u (7, ∞ )
