Help I rly need help this is the problem I'm stuck one The table shows the average monthly minimum temperature of several US cities decide whether each statement about the temperature is TRUE or FALSE

CITY AND STATE. AVERAGE MIN TEMP

Fairbanks, AK. -16.9

Fargo, ND. 0.1

Duluth, MN. 1.5

Grand Forks, ND. -3.1

#1.the temperature of Fairbanks, AK is higher than the average temperature of Grand Forks, ND is it true or false?

#2.the average temperature of Grand Forks, ND is farther from Zero than the average temperature of Duluth, MNis it true or False?

#3.teh average temperature of Fargo, ND is LOWER than teh average temperature of Grand Forks, NDis it true or false?

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
