I think it is 2x + 4 but i am not 100% sure
Formula for exponential growth is:
A = P(1+r)^t
Where A is the resulting amount, P is the initial value, r is the rate, and t is the time passed.
Filling this out for this situation gets you:
13400 = 10000(1+r)^6
Solving for r:
Divide 13400 by 10000
1.34 = (1+r)^6
Take the 6th root of both sides...
1 + r = 1.05
No more work is needed, since you aren’t solving for r.
Full equation:
V = 10000(1.05)^t
Answer C is correct
The value of x in the trapezoid given, to the nearest tenth, is: 10.5.
<h3>What is a Trapezoid?</h3>
A trapezoid is a quadrilateral that has two sides only that are parallel to each other.
<h3>What is the Area of a Trapezoid?</h3>
To find the area of a trapezoid, the formula used is expressed as: 1/2(a + b) × h, where:
- a and b are length of the two base sides that are parallel.
- h is the height of altitude of the trapezoid.
Given the following:
Area of trapezoid = 174 units²
AP = 6
PB = x + 3
CD = 2x + 6
AC = 10
Using the formula, we variables in the formula are:
a = AP + PB = 6 + x + 3 = x + 9
b = CD = 2x + 3
h = PC = √(AC² - AP²)
h = √(10² - 6²) = 8
Plug in the values into 1/2(a + b) × h:
174 = 1/2(x + 9 + 2x + 3) × 8
174 = 1/2(3x + 12) × 8
174 = (3x + 12) × 4
174 = 12x + 48
174 - 48 = 12x
126 = 12x
126/12 = x
10.5 = x
x = 10.5
