Answer:

see explanation

Step-by-step explanation:

The x- intercepts are the points on the x- axis where the graph crosses.

The graph does not cross the x- axis thus there are no x- intercepts

The y- intercept is the point on the y- axis where the graph crosses.

The y- intercept is - 6

(c)

The vertex is the turning point of the graph, in this case ∩

The vertex = (2, - 2 )

(d)

The axis of symmetry is a vertical line passing through the vertex.

The equation of the axis of symmetry is x = 2

Answer:

B

Step-by-step explanation:

√16/25 = 4/5 = 0.8-> (4/5 x 4/5 = 16/25)

(2/5)^3 = 8/125  = 0.064

-(-0.3)^3 = 0.027 (an odd exponent mantains the same sign of the number and minus x minus = +)

-√169 = -13

-13 is a negative number so it is surely the smallest

2 is minor than 6 so we have that 0.027 is minor than 0.064

8 is major than 0, so 0.8 is the greatest number

we have

-√169 ; -(-0.3)^3 ; (2/5)^3 ; √16/25

Flying with the wind a plane went 386 km/h. Flying into the same wind the plane only went 318 km/h. find the speed of the plane
zysi [14]

Answer:

Speed of plane  in air is  352 km/hr and speed of wind is 34 km/hr

Step-by-step explanation:

Average speed of plane in with wind = 386 km/h

Average speed of plane against wind = 318 km/hr

Consider the speed of plane in wind be  x km/hr and speed of plane against wind  be  y  km/hr

As such speed of plane in wind would be  x + y km/hr and speed of plane  against wind would be  x - y km/hr. i.e

x+y = 386

x-y = 318

by solving these two equation, we get

2x=704

x= 352 km/hr

y=386 - 352

y= 34 km/hr

Hence, Speed of plane  in air is  352 km/hr and speed of wind is 34 km/hr

Simplify:<br> (4xy^-6)^-3 <br><br><img src="https://tex.z-dn.net/?f=%284xy%5E%7B-6%7D%20%29%5E%7B-3%7D" id="TexFormula1" title="
Zepler [3.9K]

Answer:

(4^-3)(x^-3) y^(18)

or

y^18/ (64 x^3)

Step-by-step explanation:

(4xy^-6)^-3

Distribute the exponent to all terms in the parentheses

(4^-3)(x^-3) (y^-6)^-3

a^ b^c = a^ (b*c)

(4^-3)(x^-3) y^(-6*-3)

(4^-3)(x^-3) y^(18)

If we do not want negative exponents

a ^ -b = 1/ a^b

y^18/( 4^3 x^3)

y^18/ (64 x^3)
