Find the cosine of each acute angle

1 answer:

Lemur [1.5K]3 years ago

Answer:

cos P = 53 degrees

cos Q = 37 degrees

Step-by-step explanation:

cos P = $\frac{adjacent}{hypothenuse}$

cos P = $\frac{24}{40}$

cos P = 0.60

Cos-1 of 0.60 is 53.13 (round to the nearest whole number)

cos P = 53 degrees

cos Q = $\frac{adjacent}{hypothenuse}$

cos Q = $\frac{32}{40}$

cos Q = 0.80

Cos of 0.80 is 36.86 (round to the nearest whole number)

cos Q = 37 degrees

To check anser:

90 + 53 + 37 = 180

180 = 180

$\large \tt Solution \: :$

F(x) represents the value of y on curve for given value of x

$\textsf{\large First -}$

$\qquad \tt \rightarrow \: f(0) =( 0) {}^{2} - 3$

[ since 0 < 2 ]

$\qquad \tt \rightarrow \: f(0) = 0 {}^{} - 3$

$\qquad \tt \rightarrow \: f(0) = - 3$

$\textsf{\large Second}$

$\qquad \tt \rightarrow \: f(2) = (2) {}^{2} - 3$

[ since 2 = 2 ]

$\qquad \tt \rightarrow \: f(2) = 4{}^{} - 3$

$\qquad \tt \rightarrow \: f(2) = 1$

$\textsf{\large Third -}$

$\qquad \tt \rightarrow \: f(4) = - 4 + 5$

[ since 4 > 2 ]

$\qquad \tt \rightarrow \: f(4) = 1$

Zeolite organized a canned food drive. She worked a total of 12 2/3 hours. She worked 3 1/6 hours each day that she worked. How

galina1969 [7]

She worked 4 days on the food drive because to do math with these two fractions, you have to give them the same denominator. So, 12 2/3 becomes 12 4/6. Then, how many times does 3 go into 12? 4 times so the answer is 4. Hope this helped :)

Does this converge or diverge? Which of the follow test will be used to figure out the equation?

PSYCHO15rus [73]

From the listed choices, you can prove the series diverges using either the integral or <em>p</em>-series test.

Integral test:

We have

$\displaystyle\sum_{n=1}^\infty\ge\int_1^\infty\frac{\mathrm dx}{\sqrt x}=\lim_{x\to\infty}2\sqrt x-2$

which diverges to infinity, so the series is divergent.

<em>p</em>-series test:

The series

$\displaystyle\sum_{n=1}^\infty\frac1{n^p}$

converges only for $p>1$ . In the given sum, we have $p=\frac12$ , so the series is divergent.
