5.19cm
Step-by-step explanation:
draw perpendicular from the center of the circle to produce a right angle triangle which will have 3cm and an angle of 30 degrees. use tan to find the adjacent line which is the length of the tangent.
Answer:
a) the first negative number will be -1
b) A, B and C
c) 0.3
Step-by-step explanation:
Answer:
$5x + $7y ≥ $220
Step-by-step explanation:
Total Fees = $220
Total income is $5x plus $7y
Income = $5x + $7y
We want the total income to be equal to, or greater than, $220:
$5x + $7y ≥ $220
Using mathematical operations we can conclude that the area of the given figure is 40 units².

What are mathematical operations?</h3>
- An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value.
- The operation's arity is determined by the number of operands.
- A mathematical action is called an operation.
- Mathematical operations include addition, subtraction, multiplication, division, and finding the root.
So, the area of the figure:
Where x = 4, so the expression will become:
Now, do the mathematical operations to get the area of the figure as follows:
- x² + x² + x + x
- 4² + 4² + 4 + 4
- 16 + 16 + 8
- 40
'
Therefore, using mathematical operations we can conclude that the area of the given figure is 40 units².

Answer:
means the inverse function
=
Step-by-step explanation:
means the inverse function
to find an inverse function, flip the x and y variables and solve for y
f(x) = 5x^3 - 6
y = 5x^3 - 6
x = 5y^3 - 6
x + 6 = 5y^3
(x + 6)/5 = y^3
= y
