FIRST CORRECT GETS BRAINLIEST

BARSIC [14]

Answer:

First choice.

Step-by-step explanation:

cos 11π/6 = cos π/6 = √3/2

So cos 11π/12 = √(1 + cos 11π/6) / √2

= √(1 + √3/2) / √2

= √(2 + √3) / 2.

Suppose h is a function such that h(2) = −3, h'(2) = 3, h''(2) = 4, h(5) = 5, h'(5) = 6, h''(5) = 12, and h'' is continuous ever

Answer:

Step-by-step explanation:

It seems like your question is not complete.

So I will asume that it is like the one in the image.

But probably the answer is not 3 if the range is different from (1-2), eventhough, you just have to follow the same steps.

Determine the sum of the terms in the series 25 + 30 + 35 + ⋯ + 245. Show your work.

scoray [572]

Answer:

6075

Step-by-step explanation:

Given series is: 25 + 30 + 35 + ⋯ + 245.

Here, first term (a) = 25
Common difference (d) = 5
Last term $(a_n) = 245$

First we find the number of terms that this series has by the following formula:

$a_n = a+(n-1)d$

Plugging the values of a, d and $a_n$ , we find.

$245 = 25+(n-1)5$

$\implies 245 - 25=(n-1)5$

$\implies 220=(n-1)5$

$\implies \frac{220}{5}=n-1$

$\implies 44=n-1$

$\implies 44+1=n$

$\implies\red{\bold{ n=45}}$

Thus, the given series contains 45 terms.

Next, we find the sum of the given series using the formula given below.

$S_n = \frac{n}{2}(a+a_n)$

$\implies S_{45}= \frac{45}{2}(25+245)$

$\implies S_{45}= \frac{45}{2}(270)$

$\implies S_{45}=45*135$

$\implies\orange{\boxed{\boxed{\boxed{\bold{ S_{45}=6075}}}}}$

Para pintar 7.000 m2 se requieren 10 personas para que culminen su labor en 20 días. Sabiendo que para que la labor se realice

ValentinkaMS [17]

Answer:

C. Correct, because for the work to be carried out in 5 days, 40 workers are required.

Step-by-step explanation:

The job requires 10 people to work for 20 days. That's 200 worker-days.

In other words,

days × workers = 200 or

workers = 200/days

To get the work done in five days,

workers = 200/5 = 40.

You must hire 40 workers.

B. and D. are wrong. To get the job done in seven days. you must hire 200/7 = 29 workers.
