7. Find the percent of decrease from 290 to 100. Round to the nearest tenth of a
laiz [17]

Answer:

A 65.5%

Step-by-step explanation:

Percent decrease = (original - new)/ original * 100 percent

                              = (290-100)/290 * 100 %

                              = 190/290* 100%

                              =.655172414 * 100%

                               =65.5172414%

To the nearest tenth percent %

                                65.5%

Check all that apply. If csc =13/5 , then:
nirvana33 [79]

Answer:

The answer are the options B and C

sin(x)=\frac{5}{13}

tan(x)=\frac{5}{12}

Step-by-step explanation:

we know that

csc(x)=\frac{1}{sin(x)}

In this problem we have

csc(x)=\frac{13}{5}

substitute

\frac{13}{5}=\frac{1}{sin(x)}

solve for sin(x)

sin(x)=\frac{5}{13}

cos^{2}(x)+sin^{2}(x)=1

substitute the value of sin(x) and solve for cos(x)

cos^{2}(x)+(\frac{5}{13})^{2}=1

cos^{2}(x)=1-(\frac{5}{13})^{2}

cos^{2}(x)=(\frac{13^{2}-5^{2}}{13^{2}})

cos^{2}(x)=(\frac{144}{13^{2}})

cos^{2}(x)=(\frac{12^{2}}{13^{2}})

cos(x)=(\frac{12}{13})

The function tangent is equal to

tan(x)=\frac{sin(x)}{cos(x)}

substitute the values

tan(x)=\frac{(5/13)}{(12/13)}=5/12
