f(x) is a fancy way to say y
The equation says y=05, so x is ungiven based on what you have given us. Please check if there was more information written as usually its written as
Example: f(x)=3x+5
Answer:
1. Rhombus
2. Square
Step-by-step explanation:
1. A rhombus is a quadrilateral whose four sides all have the same length and opposite sides are parallel.
From the diagram, you can see that 
(given) and all four sides are congruent, thus this shape is a rhombus.
2. A square is a quadrilateral which has four equal sides, four equal angles (90-degree angles) and opposite sides are parallel.
From the diagram, you can see that 
(given), all four sides are congruent, and all four angles are right angles, thus this shape is a square.
Tan 32 = f/18
f = 18 × tan 32
= 11.25
= 11 ( to 2 sf)

Answer:
A) area decreases
Step-by-step explanation:
<em>Example:</em> we have a 2 by 3 rectangle with area of 2*3 = 6. If we cut the first dimension in half, then we have a 1 by 3 rectangle that has area 1*3 = 3. The area has decreased. To keep the area the same, we would have to increase the other dimension some specific amount.

Answer:
a) marked-down price = $6.00
b) with-tax cost = $6.06
Step-by-step explanation:
a) The amount of the markdown is ...
0.20 × $7.50 = $1.50
so the marked-down price is ...
$7.50 - 1.50 = $6.00
__
b) The sales tax is ...
0.01 × $6.00 = $0.06
so the total cost with tax is ...
$6.00 + 0.06 = $6.06
_____
Of course, you know that 20% = 20/100 = 0.20, and 1% = 1/100 = 0.01.
