Write the equation of a line with a slope of -7/2 passing through the point 2,-4
fiasKO [112]

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3

How do you solve: cos(x-π/3)=-1​
gladu [14]

Answer:

x = \frac{4\pi }{3}

Step-by-step explanation:

given

cos(x - \frac{\pi }{3}) = - 1, then

x - \frac{\pi }{3} = cos^{-1}(- 1) = π

Add \frac{\pi }{3} to both sides, hence

x = π + \frac{\pi }{3} = \frac{4\pi }{3}

Differentiate with respect to x:y= sinh^-1(x^2+1)
Aleks [24]

Answer:

The first derivative of y = \sinh^{-1} (x^{2}+1) is y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}.

Step-by-step explanation:

We proceed to find the first derivative of y = \sinh^{-1} (x^{2}+1) by explicit differentiation and rule of chain:

y = \sinh^{-1} (x^{2}+1)

y' = \frac{2\cdot x}{\sqrt{(x^{2}+1)^{2}+1}}

y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}

The first derivative of y = \sinh^{-1} (x^{2}+1) is y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}.
