Mathematics
1 answer:
pochemuha3 years ago
6 0

Answer:

Step-by-step explanation:

\frac{sin~x}{sec~x+1} =\frac{sin~x}{\frac{1}{cos~x}+1  } =\frac{sin~x~cos~x}{1+cos~x} \\=\frac{sin~x~cos~x}{1+cos~x} \times \frac{1-cos~x}{1-cos~x} \\=\frac{sin~x~cos~x(1-cos~x)}{1-cos^2 x} \\=\frac{sin~x~cos~x(1-cos~x)}{sin^2x} \\=\frac{cos~x(1-cos~x)}{sin~x} \\=cos ~x(csc~x-cot~x)\\or\\=cot~x(1-cos~x)

A public beach in Florida charges non residents $8 per day for a fishing license and $2.50 per day for live bait. Florida reside
melamori03 [73]

For a non-resident:

C_{nr}=8d+2.5d=10.5d

For a resident:

C_{r}=114+1d

We want to know the number of days d such that the two costs are equal ie \{d|C_{nr}(d)=C_{r}(d)\}

To do this set the two costs equal to each other:

C_{nr}=C_{r}

10.5d=114+1d

And solve for d:

10.5d-1d=114+1d-1d

9.5d=114

d=\frac{114}{9.5}

d=12

The costs will be equal when a resident and a non-resident each use the beach for 12 days.

Daniel is reading a 200-page book. He
Minchanka [31]

Set up a ratio to find the number of pages read in 80 minutes:

40 pages/ 50 minutes = x pages/ 80 minutes

Cross multiply:

50x = 3200

Divide both sides by 50:

X = 3200/50

X = 64

He will read 64 pages in 80 minutes.

200 -64 = 136

There will be 136 pages left.

The bar graph shows the number of hurricanes in the Atlantic Basin from 2006 - 2011.
7nadin3 [17]

Firstly, we will find smallest value and largest value

smallest value is in 2009

and smallest value is 3

largest value is in 2010

and largest value is 12

So, percentage change will be greatest between 2009 to 2010

now, we can find percentage change

=\frac{12-3}{3}\times 100

=\frac{9}{3}\times 100

=300 %..............Answer
