Answer:

150.43 units²

Step-by-step explanation:

The radius of the circle is 13 units. The area of the circle is πr², so the area is 169π. To get the area of the sector, we take the degrees and divide by 360, then multiply by the area.

\frac{102}{360} · 169π is about 150.43.

lozanna [386]

Answer:

Step-by-step explanation:

y = 0.80x + 2.50

a 7 mile ride......x = 7

y = 0.80(7) + 2.50

y = 5.60 + 2.50

y = 8.10 <=== the 7 mile ride cost $ 8.10

the ride cost 13.70.....y = 13.70

13.70 = 0.80x + 2.50

13.70 - 2.50 = 0.80x

11.2 = 0.80x

11.2 / 0.80 = x

14 = x <=== u travel 14 miles

There is no restrictions for x for f(x) =3✓x because you can take the cube root of any real numbers. Therefore, the domain is infinity she. dealing with the set of real numbers.

You can't take the square root of negative numbers. So, x values are restricted for f(x) = ✓x for real numbers and the domain is (0, infinity).

<h3>How to explain the domain?</h3>

It should be noted that since x cannot take negative values in the question, the square root he undefined. Hence it is an imaginary value.

Also, You can't take the square root of negative numbers. So, x values are restricted for f(x) = ✓x for real numbers and the domain is (0, infinity).
