How would I find all the solutions to the equation "7*sin^2x-14*sinx+2=-5"?

Aneli [31]

Answer:

Step-by-step explanation:

Find all solutions to the equation.

7 sin^2(x) - 14 sin x + 2 = -5

7sin^2(x)-14 sin x+7 =0

sin^2(x)-2sin x+1 =0

(sinx-1)(sinx-1)=0

sinx=1

x=π/2+2pi*k, k=integer

Hello i really need help, please help me. thank you :(

vlabodo [156]

Answer:

12/13

Step-by-step explanation:

The cosine of an angle in a triangle can be calculated as a relation between the adjacent side and the hypothenuse. So, in this case the adjacent side of θ is 24 and the hypothenuse is 26.

Then:

cos(θ) = 24/26 = 12/13

Find sum of three consecutive even integers if the largest integer is Y

KATRIN_1 [288]

Answer:

3y -- 6

Step-by-step explanation:

if the largest number is y, then the other two integers would be (y -- 2) and (y -- 4).

Therefore the sum of the integers would be

y + (y -- 2) + (y -- 4) = 3y -- 6.

Given P(x) = 2x3 - 11x2 + 18x - 15 is divided by x – 3. Use synthetic division to find the quotient and the remainder.

katrin [286]

You can find the remainder right away by simply plugging in $x=3$ . The polynomial remainder theorem guarantees that the value of $p(3)$ is the remainder upon dividing $p(x)$ by $x-3$ , but I digress...

Synthetic division yields

3   |   2   -11   18   -15
.    |           6   -15     9
- - - - - - - - - - - - - - - - -
.    |   2     -5     3     -6

which translates to

$\dfrac{2x^3-11x^2+18x-15}{x-3}=2x^2-5x+3-\dfrac6{x-3}$

(and note that $p(3)=2(3)^3-11(3)^2+18(3)-15=-6$ , as expected)
