Suppose θ is an angle in the standard position whose terminal side is in Quadrant IV and cot θ= -6/7 . Find the exact values of
Llana [10]

Answer:

Part 1) csc(\theta)=-\frac{\sqrt{85}}{7}

Part 2) sin(\theta)=-\frac{7}{\sqrt{85}}  or sin(\theta)=-\frac{7\sqrt{85}}{85}

Part 3) tan(\theta)=-\frac{7}{6}

Part 4) cos(\theta)=\frac{6}{\sqrt{85}} or cos(\theta)=\frac{6\sqrt{85}}{85}

Part 5) sec(\theta)=\frac{\sqrt{85}}{6}

Step-by-step explanation:

we know that

The angle theta lie on the IV Quadrant

so

sin(θ) is negative

cos(θ) is positive

tan(θ) is negative

sec(θ) is positive

csc(θ) is negative

step 1

Find the value of csc(θ)

we know that

1+cot^{2}(\theta)=csc^{2}(\theta)

we have

cot(\theta)=-\frac{6}{7}

substitute

1+(-\frac{6}{7})^{2}=csc^{2}(\theta)

1+\frac{36}{49}=csc^{2}(\theta)

\frac{85}{49}=csc^{2}(\theta)rewrite

csc(\theta)=-\frac{\sqrt{85}}{7} ----> remember that is negative

step 2

Find the value of sin(θ)

we know that

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

we have

csc(\theta)=-\frac{\sqrt{85}}{7}

therefore

sin(\theta)=-\frac{7}{\sqrt{85}}

or

sin(\theta)=-\frac{7\sqrt{85}}{85}

step 3

Find the value of  tan(θ)

we know that

tan(\theta)=\frac{1}{cot(\theta)}

we have

cot(\theta)=-\frac{6}{7}

therefore

tan(\theta)=-\frac{7}{6}

step 4

Find the value of cos(θ)

we know that

sin^{2}(\theta)+cos^{2}(\theta)=1

we have

sin(\theta)=-\frac{7}{\sqrt{85}}

substitute

(-\frac{7}{\sqrt{85}})^{2}+cos^{2}(\theta)=1

\frac{49}{85}+cos^{2}(\theta)=1

cos^{2}(\theta)=1-\frac{49}{85}

cos^{2}(\theta)=\frac{36}{85}

cos(\theta)=\frac{6}{\sqrt{85}} ------> the cosine is positive

or

cos(\theta)=\frac{6\sqrt{85}}{85}

step 5

Find the value of sec(θ)

we know that

sec(\theta)=\frac{1}{cos(\theta)}

we have

cos(\theta)=\frac{6}{\sqrt{85}}

therefore

sec(\theta)=\frac{\sqrt{85}}{6} ----> is positive

Sam opened a money-market account that pays 2% simple interest. He started the account with $7,000 and made no further deposits.
Pavlova-9 [17]
3 years
ar(n)=total a is the first number which is 7000 r is the common ratio which is 100%+2%=102 102 divided by 100 giving u 1.02(interest) so ar(n)=sum n is written as power.....and is the number of years so 7000*1.02(n)=(7000+420) 1.02(n)=7420/7000 1.02(n)=1.06 log10 1.02(n)=log10(1.06) ( multiply log10 with both) n=log10(1.06)/log10 (1.02) u get 2.94 which is round off to 3 so 3 years.. hope This helps :)

Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72. Is Sasha correct in thinking that the mean accurately r
mezya [45]

Answer:

Yes, Sasha is correct. The mean amount she makes is $58.33 in a day.

Step-by-step explanation:

Given that Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72

Let us arrange in ascending order

32, 43,50,65,72,88

There are 6 entries hence 3rd and 4th are middle entries

Median = (50+65)/2=115/2=57.5

Sum of all entries = 350

No of entries =6

Mean amount = average = sum/6

=350/6

=58.33

Hence mean = 58.33

Out of 4 options we get I option only right

Yes, Sasha is correct. The mean amount she makes is $58.33 in a day.
