The function g(x) = 10.73 + 8.14(x - 1) represents the charge for parking at the airport for x number of days. Which statement b

Andrews [41]

Answer:

<h3>This function states that the first hour has a fixed cost of 10.75.</h3><h3>Then, every additional hour has an additional cost of $8.14.</h3>

Step-by-step explanation:

The given function is

$g(x)=10.75+8.14(x-1)$

The statements that best represent the formula are:

This function states that the first hour has a fixed cost of 10.75.
Then, every additional hour has an additional cost of $8.14.

You can deduct that from the formula, because $x$ represents hour, so for $x=1$ , we have

$g(0)=10.75+8.14(1-1)=10.75$

Which means 1 hour costs $10.75.

Then, for $x=2$

$g(2)=10.75+8.14(2-1)=10.75+8.14=18.89$

Which means an additional hour cost $8.14 additionally.

Hi!

Elina [12.6K]

Answer:

404.09x cm³ (to 5 s.f.),

where x is the unknown height of the shape.

Step-by-step explanation:

Volume of the shape

= base area × height

= (large semicircle- small semicircle) × thickness of shape

Area of circle= $\pi {r}^{2}$

Area of semicircle= $\frac{1}{2} (\pi)( {r}^{2} )$

Diameter of small circle= 14

Radius= diameter ÷2

radius= 14 ÷2

radius = 7 cm

Area of small semicircle

$= \frac{1}{2} (\pi)( {7}^{2} ) \\ = \frac{49}{2} \pi$

Radius of large semicircle

= 35 ÷2

= 17.5 cm

Area of large semicircle

$= \frac{1}{2} (\pi)( {17.5}^{2} ) \\ = \frac{1225}{8} \pi$

Base area of shape

$= \frac{1225}{8}\pi - \frac{49}{2} \pi \\ = \frac{1029}{8} \pi$

Since the height if the shape is not given, I'm afraid I cant help you find the volume.

Let the height of the shape be x cm.

Volume of shape= $\frac{1029x}{8} \pi \: cm^{3}$
