Answer:

3) f(x) = 3(x + 2)^2 - 1.

Step-by-step explanation:

f(x) = 3x² + 12x +11

f(x) = 3(x^2 + 4x) + 11 Completing the square:

f(x) = 3[(x + 2)^2 - 4] + 11

f(x) = 3(x + 2)^2 -+3*-4 + 11

f(x) = 3(x + 2)^2 - 12 + 11

f(x) = 3(x + 2)^2 - 1.

Answer:

y = -3x-2

Step-by-step explanation:

the slope can be found using rise/run which comes out to be -3/1 and you can drop the 1 from the fraction to have -3. and then the y-intercept is found from where the line crosses the y-axis

As x increases, y increases. So this data has a positive association. The association looks to be strong, as the values all follow the trend pretty closely.

Answer=Strong Positive

Solve the system of equations. y=7x y=2x + 20 x=? y=?

alekssr [168]

X=4, y=28. 7x=2x+20, so subtract 2x from both sides and you’ll get 5x=20. Divide both sides by 5 and you’ll get x=4. Substitute this into the other equations and they will both equal 28.

Consider the following set of equations, where s, s0, x and r have units of length, t has units of time, v has units of velocity

Anna11 [10]

Answer:

Step-by-step explanation:

For an equation to be dimensionally correct the dimension of quantities on both sides of equation must be same.

Also, two physically quantities can only be added or subtracted only when their dimension are same.

here all option are dimensionally correct except the 5th option where

dimension of t= [T] whereas dimension of a/v is $\frac{LT^{-2}}{LT^{-1}}$

= T^{-1}

since, the dimension of quantities on either sides of equation are not the same the equation is dimensionally is incorrect.

I need some help with this calculus question

Over [174]

The tangent to $y$ at the point (0, 5) has a slope equal to the derivative evaluated at $x=0$ .

$y=x^4+5e^x\implies y'=4x^3+5e^x\implies y'(0)=5$

This tangent passes through the point (0, 5), so its equation is

$y-5=5(x-0)\implies y=5x+5$

The normal line passes through the same point, but is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent. So the equation for the normal line is

$y-5=-\dfrac15(x-0)\implies y=5-\dfrac x5$
