slope = (y2-y1)/(x2-x1) (x1,y1) = (2,-5) (x2,y2) = (7,1)

= (1- (-5))/(7-2)

= (1+6)/(5

If a driver takes 6 hours to get to the town market which is 336 km away from his house, what is his average speed?

aev [14]

Answer:

$56\ \text{km/h}$

Step-by-step explanation:

$t$ = Time taken = $6\ \text{hours}$

$d$ = Distance = $336\ \text{km}$

Average speed is given by

$s=\dfrac{\text{Distance}}{\text{Time}}=\dfrac{d}{t}$

$\Rightarrow s=\dfrac{336}{6}$

$\Rightarrow s=56\ \text{km/h}$

The average speed of the driver is $56\ \text{km/h}$ .

the formula for the perimeter of a square is p=4s. find the side of the square if the perimeter is 96 inches

s2008m [1.1K]

Answer:

24 inches

Step-by-step explanation:

Plug in 96 for p in the equation

96 = 4s

Divide both sides by 4 to isolate the variable

24 = s

PLEASE ANSWER! Given the functions f(x) = x2 + 6x - 1, g(x) = -x2 + 2, and h(x) = 2x2 - 4x + 3, rank them from least to greatest

Ratling [72]

Answer:

he rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.

Step-by-step explanation:

A quadratic equation is given by:

$ax^2+bx+c =0$

Here, a, b and c are termed as coefficients and x being the variable.

Axis of symmetry can be obtained using the formula

$x = \frac{-b}{2a}$

Identification of a, b and c in f(x), g(x) and h(x) can be obtained as follows:

$f(x) = x^2 + 6x - 1$

⇒ a = 1, b = 6 and c = -1

$g(x) = -x^2 + 2$

⇒ a = -1, b = 0 and c = 2

$h(x) = 2^2 - 4x + 3$

⇒ a = 2, b = -4 and c = 3

So, axis of symmetry in $f(x) = x^2 + 6x - 1$ will be:

$x = \frac{-b}{2a}$

x = -6/2(1) = -3

and axis of symmetry in $g(x) = -x^2 + 2$ will be:

$x = \frac{-b}{2a}$

x = -(0)/2(-1) = 0

and axis of symmetry in $h(x) = 2^2 - 4x + 3$ will be:

$x = \frac{-b}{2a}$

x = -(-4)/2(2) = 1

So, the rank from least to great based on their axis of symmetry:

0, 1, -3 ⇒ g(x), h(x), f(x)

So, option C is correct.
