Answer:

We know that in Quadrant 1, both sin x and cos x are positive

We are given:

cosec x = √6 / 2

Since Sin x is 1/ cosec x:

<em>Sinx = 1/cosecx</em>

Sinx = 2 /√6

From the pythagoras theorem,

Sin²x + cos²x = 1

Replacing the value of SinΘ

(2 / √6)² + cos²x = 1

4 / 6 + cos²x = 1

cos²x = 1 - (4 / 6)

cos²x = 2 / 6

cosx = √(2 /6)

Answer:

-6x² -6xh -2h²

Step-by-step explanation:

Apparently, you want ...

(f(x+h) -f(x))/h

for f(x) = 14 -2x³

That difference quotient is ...

$\dfrac{f(x+h)-f(x)}{h}=\dfrac{(14 -2(x+h)^3)-(14-2x^3)}{h}\\\\ =\dfrac{14-2(x^2 +3x^2h+3xh^2+h^3)-14+2x^3}{h}=\dfrac{-6x^2h-6xh^2-2h^3}{h}\\\\ =\boxed{-6x^2 -6xh-2h^2}$

Softa [21]

Answer:

$73,000

$43,000 + $5,000 x t

Step-by-step explanation:

Every year increase $5,000, after 6 years increase $5000 x 6 = $30,000

Her salary will be $43,000 + $30,000 = $73,000

After t years, her salary will be

$43,000 + $5,000 x t

The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different

Elanso [62]

If your PCR product size was 172 and there were 130 base pairs next to a 14 base pair repeat, then there are 3 repeats.

Given that the newly used primer amplifies 130 base pairs that are near

(a) 14 base pair and

(b) the size of the pcr product is 172

Size = (number of base pairs * number of repetitions) + Initial/Primer Amplicon Value

172 = (14 * x) + 130

172 -130 = 14x

42 = 14x

3 = x

Therefore, we can say that the PCR product has 3 repeats.
