Total charge at park, T = 2×charge on adults + 4×charge on children .
T =$(2×16 + 4×10)
T = $72
Now, Melissa's father paid $100 .
Amount her father get back is :
A = $( 100 - 72 )
A = $28
Therefore, her father get $28 back.
Hence, this is the required solution.
X^4 + (6x)^2 - 7
multiply 6x^2
6x * 6x = 36x^2
x^4 + 36 * x^2 - 7
cannot be factored more
Given:
Two rectangles are similar.
Length of first rectangle = 18 cm
Width of first rectangle = 6 cm
Width of second rectangle = 2 cm
To find:
The length of the second rectangle.
Solution:
We know that the corresponding sides of similar triangles are proportional. So,
Let x be the length of the second rectangle. Then,
Therefore, the length of the second rectangle is 6 cm.
The linear and exponential equation that matches f(2) = 12 and f(4) = 48 are y = 18x - 24 and f(x) = 3(2)ˣ respectively
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
For the exponential function, when f(2) = 12:
12 = ab² (1)
Also, at f(4) = 48:
48 = ab⁴ (2)
Hence:
a = 3, b = 2
f(x) = 3(2)ˣ
For the linear function using the points (2, 12) and (4, 48):
y - 12 = [(48 - 12) / (4 - 2)](x - 2)
y = 18x - 24
The linear and exponential equation that matches f(2) = 12 and f(4) = 48 are y = 18x - 24 and f(x) = 3(2)ˣ respectively
