Answer:

  • City A was the warmest
  • City B was the coolest

Step-by-step explanation:

If we list the temperatures from lowest to highest, they are 58, 60, 64, 68. The highest temperature was the warmest. It was recorded in City A.

The lowest temperature was the coolest. It was recorded in city B.

City A was the warmest; city B was the coolest.

I can confirm the answer is A and B. A is the hottest. B is the coolest.

Answer: C. 265.9^{\circ}F

Step-by-step explanation:

Given: The formula below can be used to find D, the difference in temperature between the pan and the room after t minutes.

D = 338e^{-0.03t}

At t= 8 minutes, we get

D = 338e^{-0.03(8)}\\\\\Rightarrow\ D = 338e^{-0.24}\\\\\Rightarrow\ D = 338(0.786627861067)\\\\\Rightarrow\ D = 265.88\approx265.9^{\circ}F

The approximate temperature of the pan after it has been away from the heat for 8 minutes=   265.9^{\circ}F

NO LINKS OR ELSE YOU'LL BE REPORTED!Only answer if you're very good at Math.
andreev551 [17]

Answer:

D.\ y = 3\sin(2(x + \frac{\pi}{4}))

Step-by-step explanation:

Given

A = 3 --- Amplitude

C = \frac{\pi}{4} --- Right phase shift

Required

Identify the function

A sinusoidal function is defined as:

y = A\sin(B(x + C)) + D

Substitute values for A and C

y = 3\sin(B(x + \frac{\pi}{4})) + D

By comparison, only option (D) has the above format where

y = 3\sin(2(x + \frac{\pi}{4}))

Hence (D) is correct

Solve the math problem
zalisa [80]

Answer:

\frac{4w {}^{8} }{9m {}^{4} }

Step-by-step explanation:

separate with like terms

\frac{4}{9} , \:  \frac{w {}^{9} }{w}  \: and \: \:  \frac{m {}^{5} }{m {}^{9} }

the first fraction can be left alone as it can't be simplified any further

the second fraction can be written as w⁹ ÷ w¹ , when the bases are the same and division is involved subtract the powers: 9 - 1 = 8, so it's simplified to w⁸

the third fraction can be written as m⁵ ÷ m⁹, subtract the powers: 5 - 9 = -4, so it's simplified to m⁻⁴

{m}^{ - 4}  =  \frac{1}{m {}^{4} }

putting it together:

\frac{4w {}^{8} }{9m {}^{4} }
