2. Describe two methods to determine whether ratios form a proportion.
Phantasy [73]

Answer:

1. Write both ratios as fractions and reduce them completely. If they are the same fraction, the ratios form a proportion.

2. Write both ratios as fractions. Do the cross products by multiplying the denominator of each fraction by the numerator of the other fraction. If the cross products are equal, the ratios form a proportion.

What is the value of k?
seraphim [82]

Answer:

k=2

Step-by-step explanation:

We have got a right triangle LNO with sides = m,4 and 8

By Pythagorean theorem

m^2=4^2 +8^2

Or m^2 = 80  ... i

IN triangle NOM, 4^2 +k^2 = l^2

i.e. 16+k^2 = l^2... i

In triangle LNM, m^2+l^2 = (8+k)^2

Substitute for m^2 as 80,

i.e. 80+l^2 = 64+k^2 +16k  ... iii

From i, l^2 = 16+k^2

Substitute in iii

80+16+k^2 = 64+k^2 +16k

16k = 32 or k =2

Find the domain and range of each relation. Then determine if the relation is a function. D={-2, -1, 3, 5}, R={-7 ,0 ,4} Functio
poizon [28]

Answer:

D = \{-2,-1,3,5\} -- Domain

R = \{-7,0,4\} -- Range

It is a function

Step-by-step explanation:

Given

D = \{-2,-1,3,5\}

R = \{-7,0,4\}

Required

State the domain and range

Determine if the relation is a function

From the question, we have the domain and range as:

D = \{-2,-1,3,5\} -- Domain

R = \{-7,0,4\} -- Range

Next, is to determine if the relation is a function or not.

Yes, it is a function.

The number of elements in the domain is 4

The number of elements in the range is 3

<em>When the domain has more elements than the range, this is called a many-to-one function, and it is a valid type of function.</em>
