Answer:

2300

Step-by-step explanation:

We are given that

Out of 200 , four ducks are tagged.

We have to find the number of ducks in the preserve if 46 ducks are tagged.

Let x be the number of ducks in the preserve.

If number of tagged ducks increases then number of preserved ducks also increases.It is in direct proportion.

According to question

\frac{x}{46}=\frac{200}{4}

x=\frac{200\times 46}{4}

x=50\times 46

x=2300

Answer:

Step-by-step explanation:

Amount paid for first 100 watches = (65% of 80) *100

                                                        =\frac{65}{100}*80*100\\\\= 65*80\\= 5200

Amount paid for next 50 watches = (55% of 80) * 50

                                                        = \frac{55}{100}*80*50\\\\= 55 * 8 * 5\\\\= 2200

Remaining watches = 280 -(100+ 55)

                                 = 280 - 155 = 125

Amount paid for 125 watches = (45% of 80) *125

                                                  = \frac{45}{100}*80*125\\\\= 45 * 20 * 5\\\\= 4500

Amount received by the watch maker = 5200 + 2200 + 4500

                                                               = £ 11900

Based on the family the graph below belongs to, which equation could represent the graph?
pav-90 [236]

The correct equation which represents the graph is y = log (2x) + 3. Then the correct option is B.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The equations are given below.

The graph of the function y = 2ˣ + 3 approaches zero when the value of x goes to negative infinity.

The graph of the function y = log (2x) + 3 approaches the negative infinity when the value of x approaches zero.

The graph of the function y = 2x² + 2 is parabolic in nature.

Then the correct equation which represents the graph is y = log (2x) + 3.

More about the function link is given below.
