Answer:

DG = 16 cm

Step-by-step explanation:

DG is one- third of AD , then

DG = [tex]\frac{1}{3}[/tex] × 48 = 16

The length of the segment DG will be equal to 16 cm.

Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial qualities such as figure distance, shape, size, and relative position. A geometer is a mathematician who works in the field of geometry.

Given In the diagram below of triangle ABC, medians AD, BE and CF intersect at point G  and the length of AD is 48 cm.

The length of the segment DG will be calculated as,

DG is one-third of AD, then

DG = ( 1 / 3 ) × 48

DG = 16

Therefore, the length of the segment DG will be equal to 16 cm.

The standard form of the vertex form equation is y = 2x² - 12x + 17

The vertex form of a quadratic equation is represented as:

y = a(x - h)² + k

Using the above form, the quadratic equation can be represented as:

y = 2(x - 3)² + 1

Expand

y = 2(x² - 6x + 9) - 1

Further expand

y = 2x² - 12x + 18 - 1

Evaluate the like terms

y = 2x² - 12x + 17

Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

Answer:

Total amount pay by Ben = $82.27 (Approx.)

Step-by-step explanation:

Given:

2 Shirts = $16 each

3 pairs of socks = $2.50 each

1 pair of jeans = $37.75 each

Sales tax = 6.5%

Find:

Total amount pay by Ben

Computation:

Total amount for shirts = 2 x 16

Total amount for shirts = $32

Total amount for socks = 3 x 2.50

Total amount for shirts = $7.50

Total amount before tax = $32 + $7.50 + $37.75

Total amount before tax = $77.25

Total amount pay by Ben = Total amount before tax[1+tax]

Total amount pay by Ben = 77.25[1+6.5%]

Total amount pay by Ben = $82.27 (Approx.)

Answer: 293 miles

Step-by-step explanation:

First remove the fixed cost of the base fee so we can find out the amount spent on the miles driven:

= 267.11 - 20.99

= $246.12

Alan is charged 84 cents for each mile driven and the total came to $246.12.

84 cents in dollar notation = $0.84

The total miles driven is therefore:

= 246.12 / 0.84

= 293 miles
