We have slope intercept form.  Parallel means the same slope, and we get to choose the intercept to fit the new point (-6,0).

y = (1/3) x + b

0 = (1/3) (-6) + b

2 = b

Answer y = (1/3) x + 2 third choice

How do you find the absolute extrema of this function?<br> f(x) = x+3x^(2/3); Interval is [-10,1]
Step2247 [10]
\bf f(x)=x+3x^{\frac{2}{3}}\implies \cfrac{dy}{dx}=1+3\left(\frac{2}{3}x^{-\frac{1}{3}}  \right)\implies \cfrac{dy}{dx}=1+\cfrac{2}{\sqrt[3]{x}}&#10;\\\\\\&#10;\cfrac{dy}{dx}=\cfrac{\sqrt[3]{x}+2}{\sqrt[3]{x}}\implies 0=\cfrac{\sqrt[3]{x}+2}{\sqrt[3]{x}}\implies 0=\sqrt[3]{x}+2\implies -2=\sqrt[3]{x}&#10;\\\\\\&#10;(-2)^3=x\implies \boxed{-8=x}\\\\&#10;-------------------------------\\\\&#10;0=\sqrt[3]{x}\implies \boxed{0=x}

now, f(0) = 0, and f(-8) is an imaginary value or no real value.

now, f(-10)   will also give us an imaginary value

and f(1) = 4

so, doing a first-derivative test on 0, is imaginary to the left and positive on the right, and before and after 1, is positive as well, so f(x) is going up on those intervals.

however, f(0) is 0 and f(1) is higher up, so the absolute maximum will have to be f(1), and we can use f(0) as a minimum, and since it's the only one, the absolute minimum.

the other two, the endpoint of -10 and the critical point of -8, do not yield any values for f(x).

Please help!!!

Answer:

Rs.833.94

Step-by-step explanation:

To solve for the sum of money or principal, we use the formula:

P=\dfrac{A}{1+rt}

The current variables we have are:

A = Rs.1,155

r = 11% or 0.11

t = 3.5

Now let's plug the variables into the formula.

P=\dfrac{A}{1+rt}

P=\dfrac{1,155}{1+(0.11)(3.5)}

P=\dfrac{1,155}{1+0.385}

P=\dfrac{1,155}{1.385}

P=Rs.833.94

The sum of three consecutive integers is 45. What are the integers
Blababa [14]

Divide 45 by 3 ( the quantity of consecutive numbers) This will give you the middle number, then use the number higher and lower.

45/3 = 15

14 + 15 + 16 = 45

The 3 numbers are 14, 15 and 16
