10. During his weather report after the last snowstorm, a Baltimore meteorologist reported the low temperature was 26°F at 6 a. m. The high
temperature was 44°F, and occurred at 6 p. m. The temperature in Baltimore on
this day can be modeled by the sinusoidal functionT = a · sin (r12 x) + d where T
represents the temperature in degrees Fahrenheit x hours. Determine the values
for the amplitude and midline. Write the numbers in the blank space below, and
Please remember to LABEL your answers.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

the answer is a if my teacher taught me correct

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
