Answer:

We have to find the solution ultimately. Let's start with the substitution of the values. Given that k = 2, equation becomes 3×2 (2×2 + 4). Let's solve it. Therefore we get 6(4+4). You can solve it further to get the value. It will become 6(8). We know that 6×8 = 48 so the value is 48.

pls give brainliest for the answer

Questione Simplify Cosa + 2Cos(a +240")

melamori03 [73]

Step-by-step explanation:

$\cos(a) + 2 \cos(a + 240)$

$\cos(a) + 2 \cos(a) \cos(240) - \sin(a) \sin(240)$

$\cos(a) + 2( - \frac{ \cos(a) }{2} + \frac{ \sqrt{3} }{2} \sin(a) )$

$\cos(a) - \cos(a) + \sqrt{3} \sin(a)$

$\sqrt{3} \sin(a)$

If you graph the new identity, and the og identiy, they will be conciding graphs, so they are the same identity.

Which pair of numbers is relatively prime? A. 42 and 77 B. 34 and 55 C. 45 and 102 D. 99 and 123

leonid [27]

Two pair of numbers are said to be relatively prime if there is no integer greater than 1, that divides them both.

Consider the given pair of the numbers to identify which pair is relatively prime.

1. Consider 42 and 77

7 is the number which divides 42 and 77 both. Therefore, they are not relatively prime.

2. Consider 34 and 55

Since, there is no number greater than 1, which divides both the numbers. So, they are relatively prime numbers.

3. Consider 45 and 102

3 is the number divides 45 and 102 both. Therefore, they are not relatively prime.

4. Consider 99 and 123

3 is the number divides 99 and 123 both. Therefore, they are not relatively prime.

Therefore, Option B is the correct answer.

Calculus: Help ASAP

wariber [46]

$\bf \displaystyle \int~\cfrac{sec^2(x)}{\sqrt{1+tan(x)}}\cdot dx\\\\
-------------------------------\\\\
u=1+tan(x)\implies \cfrac{du}{dx}=sec^2(x)\implies \cfrac{du}{sec^2(x)}=dx\\\\
-------------------------------\\\\
\displaystyle \int~\cfrac{\underline{sec^2(x)}}{\sqrt{u}}\cdot\cfrac{du}{\underline{sec^2(x)}}\implies \int~\cfrac{1}{\sqrt{u}}\cdot du\implies \int~u^{-\frac{1}{2}}\cdot du
\\\\\\
2u^{\frac{1}{2}}\implies 2\sqrt{1+tan(x)}+C$

What effect does changing the function f (x) = 2 sin (x/2)- 1 to the function g(x) = 2 sin (x) - 5 have on the graph of f(x)?

mario62 [17]

Answer:

choice 4 (or D)

Step-by-step explanation:

1) the initial argument (x/2) and the final one (x) shows horizontal compression of the given function;

2) the different between (-1) and (-5) is (-4); it means shifting down 4 units;

3) the correct answer is: t<u>he graph is compressed horizontally by a factor 2 and shifted down 4 units</u>.
