Determine whether this graph is a function

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
4 0

Step-by-step explanation:

A function is such that every element in the domain has only 1 image in the range. The domain here are the x-values while the range is the y-values.

However a vertical line can cross the graph more than once. Hence the graph is not a function.

Georgia [21]

Answer:

(1)55.5 feet

(2)7.5 feet

Step-by-step explanation:

<u>Question 1</u>

The diagram is attached below.

Using Trigonometric ratio

\tan 48^\circ = \dfrac{h}{50} \\h=50 \times \tan 48^\circ\\h=55.5$ feet (to the nearest tenth)

The height of the house is 55.5 feet to the nearest tenth.

<u>Question 2</u>

In the diagram, we are required to find the distance the bird must fly to be directly above the fish. This has been represented by x.

Using Trigonometric ratio

\tan 15^\circ = \dfrac{2}{x} \\x \tan 15^\circ=2\\x=2 \div \tan 15^\circ\\x=7.5 $ feet (to the nearest tenth)

The distance the bird must fly to be directly above the fish is 7.5 feet.

MariettaO [177]

Answer:

A.) 0.0129 = k

B.) 2024

Step-by-step explanation:

A.)

267,000 = 250,300e^k5

267,000/250,300 = e^k5

1.0667 = e^k5

ln(1.0667) = lne^k5

ln(1.0667) = 5k

ln(1.0667)/5 = k

0.0129 = k

B.)

300,000 = 250,300^0.0129t

300,000/250,300 = e^0.0129t

1.1986 = e^0.0129t

ln(1.1986) = lne^0.0129t

ln(1.1986) = 0.0129t

ln(1.1986)/0.0129 = t

14.03 = t

so the year would be: 2024
