F ( x ) = x³ + 3 x² - 9 x - 8We have to derive this function:f ` ( x ) = 3 x² + 6 x - 93 x² + 6 x - 9 = 0   /:3x² + 2 x - 3 = 0x² + 3 x - x - 3 = 0x ( x + 3 ) - 1 · ( x + 3 ) = 0( x + 3 ) · ( x - 1 ) = 0x1 = - 3,  x2 = 1f max = f ( - 3 ) = - 27 + 27 +27 - 8 = 19f min = f ( 1 ) = 1 + 3 - 9 - 8 = - 13Answer:B ) The relative maximum is at ( - 3 , 19 ) and the relative minimum is at ( 1 , - 13 ).

True [87]
Well for every 9 Tuesday’s that she goes, she gets 3, so since 9•4 equals 36, then to solve you multiply 3 times 4, equals 12, so she will most likely get 12 coupons in the next year

Suppose m is in the line given by the equation 6x-3y=7, and suppose n is the line perpendicular to m and passing Nd through the
stealth61 [152]

Answer:

The x co-ordinate o intersection of line k and n is \frac{8}{11}

Step-by-step explanation:

Given as :

The equation of line m is 6 x - 3 y = 7

So, in the standard form , line equation is

y = a x + c  , where a is the slope

So,  6 x - 3 y = 7 can be written as

3 y = 6 x - 7

or,  y = 2 x - \frac{7}{3}       ........1

So, slope of this line = a = 2

Now, The line n is perpendicular to line m and passing through line ( 6 , 2 )

So, Slope of line n = b

For , perpendicular lines , products of slope = - 1

Or, a × b = -1

∴  b = - \frac{1}{a}

I.e b = - \frac{1}{2}

So,equation of line n with slope b and passing through line ( 6 , 2 ) is

y - y_1 = b ( x - x_1 )

or, y - 2 =  - \frac{1}{2} ( x - 6 )

or, 2 × ( y - 2 ) =  - 1 ( x - 6 )

or, 2 y - 4 = - x + 6

or, x + 2 y -10 = 0          ........2

Again, equation of line k with slope 5 and y intercept = 1

For y intercept , x coordinate = 0

y = c x + c

or, 1 = c× ( 0 ) + c

Or, c = 1

Or, equation of line k is

y = 5 x + 1           ..........3

Now intersection of line k and n is

put the value of y from eq 3 into eq 2

I.e x + 2 × (  5 x + 1  )-10 = 0  

Or, x + 10 x + 2 - 10 = 0

or, 11 x - 8 = 0

or 11 x = 8

∴  x = \frac{8}{11}

Hence The x co-ordinate o intersection of line k and n is \frac{8}{11}  Answer
