What is the length of segment ae
Usimov [2.4K]
<h3>Answer: 4 units</h3>

=================================================

Work Shown:

Start at point A' and count how many spaces it takes to get to E'. You should count out 6 spaces. This means A'E' = 6

Since A'E' is 6 units long, and the scale factor is 3/2 = 1.5, this means we can say

x = length of AE

y = length of A'E' = 6

x*1.5 = y

x*1.5 = 6

x = 6/1.5

x = 4

Segment AE is 4 units long

Lawrence sells 40% of the apples on his cart, and are left with 420 apples. How many apples had Lawrence started with?
lutik1710 [3]

Answer:

700 apples

Step-by-step explanation:

Let

x = Total number of apples in the cart

Percentage of apples sold = 40%

Number of apples sold = Percentage of apples sold * Total number of apples in the cart

= 40% * x

= 0.4 * x

= 0.4x

Number of apples left in the cart = 420

Total number of apples in the cart = Number of apples sold + Number of apples left in the cart

x = 0.4x + 420

x - 0.4x = 420

0.6x = 420

x = 420/0.6

x = 700

x = Total number of apples in the cart = 700

Lawrence started with 700 apples

The graph below shows three functions: Graph of function f of x equals 2 to the power of negative x. Graph of function g of x eq
jeyben [28]

The straight line is a polynomial. ALL polynomials have real numbers as its domain.


The exponential functions f(x) and g(x) both have the form b^x or b^(-x). Both these exponential functions have a real domain, but the range of both are limited to strictly positive numbers.
