The graph of y = sqrt x is translated. The translation is defined by (x,y) + (x-3,y +1). Which is the graph of the translated im
Nuetrik [128]

The resulting function will have a function f(x) = √x-3 -1

<h3>Translation of coordinates</h3>

Translations is a transformation technique that changes the position of an object from one point on the plane to another.

Given the function below

y = √x

If the translated technique below is applied  (x,y) -> (x-3,y +1), the resulting function is given as:

y+1  = √x-3

Subtract 1 from both sides

y + 1 - 1 = √x-3 - 1

y = √x-3 -1

Hence the resulting function will have a function f(x) = √x-3 -1

Boubacar went to the store to buy some walnuts. The price per pound of the walnuts
Inessa05 [86]

Answer:

Step-by-step explanation:

Price per pound of the walnuts = $ 6.50

Price of 4 pounds of the walnuts = 4 *6.50 = $ 26

Amount needs to be paid = Price of 4 pounds of walnut - coupon amount

             = 26 - 3.75

              = $ 22.25

Expression:

Cost to buy p pounds of walnuts = p * 6.50 = 6.5p

Cost to buy p pounds of walnuts, assuming at least one pound is purchased =  6.50 + 6.5p

san4es73 [151]

Answer:

Step-by-step explanation:

1). ∵ 1 L = 1000 ml

   ∴ 4 L = 4000 ml

2). ∵ 1 cm = 10 mm

    ∴ 5 cm = 50 mm

3). ∵ 1 mg = 0.1 cg

    ∴ 5 mg = 0.5 cg

4). ∵ 1 ml = 0.001 L

    ∴ 25 ml = 0.025 L

5). ∵ 1 gm = 1000 mg

    ∴ 0.125 gm = 25 mg

6). ∵ 1 ml = 0.001 L

    ∴ 570 ml = 0.57 L

7). ∵ 1 mm = 0.1 cm

    ∴ 135 mm = 13.5 cm

8). ∵ 1 mg = 0.001 g

    ∴ 1820 mg = 1.82 g

9). ∵ 1 g = 100 cg

    ∴ 0.5 g = 50 cg

10). ∵ 1 ml = 0.001 L

     ∴ 0.2385 ml = 0.0002385 L
