the current temperature in smalltown is 20 °F this is 6 degrees less than twice the temperature thst that it was six hour ago wh
ira [324]
<span>2 x - 6 = 20, where x is the temperature in degrees Farhenheit 6 hours ago. 2 x = 20 + 6, 2 x = 26, x = 26 : 2, x = 13 degrees F. We can prove it: 13 * 2 - 6 = 26 - 6 = 20 degrees F ( the current temperature ) Answer: The temperature 6 hours ago was 13 degrees F.Hope this helps. Let me know if you need additional help!</span><span />

Find the slope of the curve below at the given points. Sketch the curve along with its tangents at these points. R = sin 2 theta
mr Goodwill [35]

Answer:

<u>    </u><u>-1     </u>

Step-by-step explanation:

Given that:

r = sin 2θ  , θ = ± π/4 , ± 3π/4

Recall that:

x = r cosθ

y = r sinθ

The  differential of y with respect to x

\dfrac{dy}{dx} = \dfrac{\dfrac{dy}{d \theta}}{\dfrac{dx}{d \theta}}

\dfrac{dy}{dx} =\dfrac{\dfrac{dy}{d \theta}}{\dfrac{dx}{d \theta}} = \dfrac{ r cos \theta + sin \theta* \dfrac{dr}{d \theta} } {\dfrac{dr}{d \theta} *cos \theta- sin \theta \ r}

at  θ = π/4  , r = sin π/2

r = 1

\dfrac{dy}{dx} = \dfrac{ r cos \theta + 2 cos (2 \theta)*sin \ \theta } {2 \ cos (2 \theta) *cos \theta- sin 2 \theta * sin \theta}

where;

θ = π/4

\dfrac{dy}{dx} = \dfrac{ 1 \times  cos (\dfrac{\pi}{4}) + 2 cos  (\dfrac{\pi}{2})*sin  (\dfrac{\pi}{4}) } {2 \ cos  (\dfrac{\pi}{2})*cos  (\dfrac{\pi}{4})- sin  (\dfrac{\pi}{2}) * sin  (\dfrac{\pi}{4})}

\dfrac{dy}{dx} = \dfrac{\dfrac{1}{\sqrt{2}}+0 }{0-1 * \dfrac{1}{\sqrt{2}}}

\dfrac{dy}{dx} = \dfrac{\dfrac{1}{\sqrt{2}} }{- \dfrac{1}{\sqrt{2}}}

\mathbf{\dfrac{dy}{dx} =-1}

slope of the curve (dy/dx) at theta(θ)  = pi/4 is -1

What output is twice the sum of the input 3 and 4
Andreas93 [3]

Answer:

Required output = 14

Step-by-step explanation:

Sum of the input 3 and 4 = 3 + 4

Twice the sum means two times.

So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.

2(3 + 4)

Perform the addition inside the parentheses.

2(3 + 4) = 2(7)

Now, multiply.

2(3 + 4) = 14

Hence, required output = 14
