Write the following in terms of sin(θ) and cos(θ); then simplify if possible.

1 answer:

5 0

The solution to the problem is as follows:

cot θ = cos θ / sin θ 
So sinθ * cot θ = cos θ after cancelling sin θ 
Now cosθ + sin θ cot θ = cos θ + cos θ = 2 cos θ

Answer:

The slope of tangent at point (1,-2) is $\frac{2}{3}$ .

Step-by-step explanation:

The given equation of ellipse is

$2x^2+xy+y^2=4$

Differentiate both sides with respect to x.

$\frac{d}{dx}(2x^2+xy+y^2)=\frac{d}{dx}(4)$

$\frac{d}{dx}(2x^2)\frac{d}{dx}(xy)+\frac{d}{dx}(y^2)=\frac{d}{dx}(4)$

$4x+x\frac{dy}{dx}+y+2y\frac{dy}{dx}=0$

$(4x+y)+(x+2y)\frac{dy}{dx}=0$

$\frac{dy}{dx}=-\frac{4x+y}{x+2y}$

Calculate the value of \frac{dy}{dx} at (1,-2).

$\frac{dy}{dx}_{(1,-2)}=-\frac{4(1)+(-2)}{(1)+2(-2)}$

$\frac{dy}{dx}_{(1,-2)}=-\frac{2}{-3}$

$\frac{dy}{dx}_{(1,-2)}=\frac{2}{3}$

Therefore the slope of tangent at point (1,-2) is $\frac{2}{3}$ .

nydimaria [60]

The volume of the box when it's filled to 3 inches deep is 12×8×3 = 288 in³

The box is filled up to 1.5 inches from the top, that means the box is filled only
3-1.5 = 1.5 inches deep

The volume of the box when it's filled to 1.5 inches deep is 12×8×1.5 = 144 in³

The number of flours saved is 288 - 144 = 144 in³

What is 47.2 % of 300 ?

kupik [55]

For this type of question, you just need to multiply the percentage with the number
so, the calculation would be

47.2% x 300

47.2/100 x 300

47.2 x 3

= 141.6
