Maslowich

Answer:

f(x)=1/2x-5

Step-by-step explanation:

first f(0)=-5 is the y intercept and then you can find the slope using those two points to then find the slope intercept equation y=mx+b

The length of the base edge of a pyramid with a regular hexagon base is represented as x. The height of the pyramid is 3 times l

sergij07 [2.7K]

Answer:

(a)

h=3x

(b)

$A=\frac{\sqrt{3} }{4} x^2$

(c)

$A=\frac{3\sqrt{3} }{2} x^2$

(d)

$V=\frac{3\sqrt{3} }{2} x^3$ units^3

Step-by-step explanation:

We are given a regular hexagon pyramid

Since, it is regular hexagon

so, value of edge of all sides must be same

The length of the base edge of a pyramid with a regular hexagon base is represented as x

so, edge of base =x

b=x

Let's assume each blank spaces as a , b , c, d

we will find value for each spaces

(a)

The height of the pyramid is 3 times longer than the base edge

so, height =3*edge of base

height=3x

h=3x

(b)

Since, it is in units^2

so, it is given to find area

we know that

area of equilateral triangle is

$=\frac{\sqrt{3} }{4} b^2$

h=3x

b=x

now, we can plug values

$A=\frac{\sqrt{3} }{4} x^2$

(c)

we know that

there are six such triangles in the base of hexagon

So,

Area of base of hexagon = 6* (area of triangle)

Area of base of hexagon is

$=6\times \frac{\sqrt{3} }{4} x^2$

$=\frac{3\sqrt{3} }{2} x^2$

(d)

Volume=(1/3)* (Area of hexagon)*(height of pyramid)

now, we can plug values

Volume is

$=\frac{1}{3}\times\frac{3\sqrt{3} }{2} x^2\times (3x)$

$V=\frac{3\sqrt{3} }{2} x^3$ units^3

Round it to nearest fifths

Yanka [14]

Answer:

mean = $11.15

median = $11.30

mode = $9.90, $10.70, $11.90, $12.05

Step-by-step explanation:

Ordered from smallest to largest

9.89, 10.71, 11.90, 12.06

The mean is the middle number.

There are two numbers in the middle so you have to add them together and divide by 2.

(10.71 + 11.90)/2 = 11.305

rounded 11.30

Mode is the number that appears the most. All of the prices are listed once. They are all the mode.

Mean is (10.71+11.90+9.89+12.06)/4 = 11.14

round 11.15
