Answer:

Step-by-step explanation:

2x² - 3x - 15 = 5

2x² - 3x - 20 = 0

Quadratic formula

x = [3 ± √(3² – 4·2(-20))] / [2·2]

= [3 ± √169] / 4

= [3 ± 13] /4

= -2.5, 4

Answer:

b. cosx + 6 sinx

Step-by-step explanation:

$\frac{d}{dx} ( sinx - 6 cos \: x) \\ \\ = \frac{d}{dx} sinx - 6\frac{d}{dx} cos \: x \\ \\ = cos \: x - 6( - sin \: x) \\ \\ = cos \: x + 6 \: sin \: x$

Solve for x in the picture please

Nutka1998 [239]

Answer: $x=1$

Step-by-step explanation:

In order to find the value of "x", it is important to remember that:

$Tangent\ chord\ angle=\frac{1}{2}(Intercepted\ arc)$

We can identify in the figure that:

$Tangent\ chord\ angle=(43x)\°\\\\Intercepted\ arc=AB$

Then:

$43x=\frac{1}{2}AB$

Solving for AB:

$2(43x)=AB\\\\AB=86x$

Now, since there are 360° in a circle, we know that:

$AB+(272x+2)=360$

Then we can substitute $AB=86x$ into $AB+(272x+2)=360\°$ and solve for "x". This is:

$(86x)+(272x+2)=360\\\\358x=360-2\\\\x=\frac{358}{358}\\\\x=1$
