Math section -- no calculatormeteorologists in atlanta have developed the following equation to estimate the temperature t , in degrees fahrenheit , based on the number of hours h after sunrise until 4: 00 pm: t = 5h + 61.4according to this model , by how many degrees fahrenheit will the temperature rise each hour until 4: 00 pm? a) 3.3b) 5c) 12.3d) 30.7

The answer is b, 5 degrees. The equation means that the temperature will be 61.4 degrees + 5 degrees each hour until 4 pm.

b) 5

Explanation:

The equation for the temperature in Fahrenheit is:

t = 5h + 61.4  

Where h is the number of hours after 4:00 pm

then if this is compared with a linear equation, the y-intercept is 61.4 Fahrenheit, and the slope is 5 Fahrenheit/hour

Now we want to know by how many degrees Fahrenheit will the temperature rise each hour until 4:00 PM, we need to look at the slope in order to answer this.

We know that the slope is 5 Fahrenheit/hour, so each hour that passes the temperature increases by 5 degrees Fahrenheit.

The right option is b) 5.

the answer is:

in a biology class, the teacher started explaining a new lesson about the dna structure. personally, i found this lecture hard to understand. so i decided to use my critical thinking skills to be able to understand it. i analysed the different ideas, and broke them down into smaller parts to assimilate each. then i started evaluation and tried to link what i am learning with real life experiences so that i can make sure that i know how everything i am learning relates. finally, i started questioning by researching more what i learned and asking more questions that can me through my learning process. reflecting on the information meant that i should review it. all this me greatly understand what i previously found hard to understand.

hope it !
