This graph shows the temperature of a room over time. how many °f does the temperature of the room increase by every 1 min? enter your answer in the box. °f

Solution:

Graph of temperature of a room(°F) and time(T) is given in the graph.

When Time increases temperature of a room also increases.

It means time is in directly proportional to temperature.

We can Find  equation of line using two point slope formula.

The line passes through (0,65) and (20,75).

X coordinate = Time, Y coordinate = Temperature

Equation of line passing through

Equation of line passing through (0,65) and (20,75) is given as:

⇒

When t=1 i.e x=1

1 - 2 y + 130 = 0

2 y = 131

y = 65.5°F

The temperature increases by 0.5° C with every increase of time by 1 minute.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
