For a drag race car that weighs 1600 kilograms, the velocity v (in kilometers per hour) reached by the end of a drag race can be

modeled by the function v=23.8\sqrt[3]{p} , where p is the car's power (in horsepower). Estimate the power of a 1600-kilogram car that reaches a velocity of 220 kilometers per hour. Round your answer to the nearest whole number.

HELP PLZZ ASAP !! a. The value of x is 6 , what is the value of y?
erastovalidia [21]

Answer:

a). y = 4.5

b) Scale factor = \frac{3}{4}

Step-by-step explanation:

a). Since, polygon Q is the scaled copy of polygon P

    Both the figures will be similar.

    Therefore, their corresponding sides will be proportional.

    \frac{x}{y} =\frac{4}{3}

    If x = 6,

    \frac{6}{y} =\frac{4}{3}

    y = \frac{3\times 6}{4}

    y = 4.5

b). Since, polygon Q is the scaled copy of polygon P,

    Polygon Q will be the image of preimage polygon P.

    Scale factor = \frac{\text{Length of a side of the image}}{\text{Length of a side of the preimage}}

                         = \frac{3}{4}
