Answer:
Sales amount = $ 300.08
Step-by-step explanation:
Sale amount = selling price + sales tax
Here selling price = $300
sales tax = 8 %
sale amount = 300 + 8%
= 300 +
=( 300 ×100 + 8 )÷100
= (30000 + 8 ) ÷ 100
= 30008 ÷ 100
=$ 300.08
Sales amount = $ 300.08
Answer:
The total price of the bicycle including sales tax is $324
Step-by-step explanation:
The price of a bicycle = $300
Rate of sales tax = 8%
Amount of tax =
=
=
= 24
Cost of bicycle including tax= Price of cycle + Amount of tax = 300+24=324
So, total price of bicycle = $324
Hence the total price of the bicycle including sales tax is $324

Answer:
f(8) = -30 is the maximum
Step-by-step explanation:
The equation is that of a parabola in vertex form:
y = a(x -h)^2 +k . . . . . . . . (h, k) is the vertex; 'a' is the scale factor
Comparing this form to the given equation, we have ...
f(x) = -(x -8)^2 -30
That is, the scale factor is -1, and the vertex is (8, -30).
When the scale factor is negative, the graph opens downward and the vertex is a maximum. The maximum value is -30.
<u>Given</u>:
Given that Corey is flying a kite with 105 meters of string.
The string makes an angle of 42° with the ground level.
We need to determine the height of the kite.
<u>Height of the kite: </u>
The height of the kite can be determined using the trigonometric ratio.
Thus, we have;
From the given data, the values are , opp = h (height of the kite) and hyp = 105 meters.
Substituting the values, we get;
Multiplying both sides of the equation by 105, we get;
Rounding off to the nearest meter, we get;
Thus, the height of the kite is 70 meters.
