Identify the values of the variables. Give your answers in simplest radical form. HELP PLEASE!!!
galben [10]

Answer:

x = 3\sqrt{2}

y = 6\sqrt{2}

Step-by-step explanation:

The triangle is a 30-60-90 right triangle.

The ratio of the lengths of the sides is:

1 : \sqrt{3} : 2

The order of the sides in the ratio above is

short leg : long leg : hypotenuse

The long leg is sqrt(3) times the length of the short leg.

x \times \sqrt{3} = 3\sqrt{6}

x = \dfrac{3\sqrt{6}}{\sqrt{3}}

x = 3 \times \sqrt{\dfrac{6}{3}}

x = 3\sqrt{2}

The hypotenuse is twice the length of the short leg.

y = 2 \times 3\sqrt{2}

y = 6\sqrt{2}

The temperature T in degrees Fahrenheit is (approximately) a linear function of the number C of cricket chirps per minute. Twent
Law Incorporation [45]

Answer:

a) T= 0.25 C+37

b) T= 62°F

Step-by-step explanation:

Here T is a linear function of C

T= mC+b

For each additional chirp C corresponding to an increase in T of 0.25

therefore, m= 0.25

T= 42° F   C=20 ( given)

therefore,

a) 42= 0.25×20+b

b= 37

therefore T= 0.25 C+37

b) now C= 100

therefore, T= 0.25×100+37 = 62°F
