Explanation:
Sealed combustion heaters are much safer to operate than other types of space heaters, and operate more efficiently because they do not draw in the heated air from the room and exhaust it to the outdoors. They are also less likely to backdraft and adversely affect indoor air quality.
Less expensive (and less efficient) units use the room air for combustion. They do not have a sealed glass front to keep room air away from the fire and should not be confused with a sealed combustion heater.
Answer:
f(x) = d/ dx (2.5x1.3)
f(x) =2.5×d/dx(1.3*)
f(x) =5xIn 13/10 x 13*/2×10*
So the answer is
f(x)=5•IN13/10•13*/2•10*
That's the correct answer I see in my book
All offsprings will be Yy; all of them will be yellow seeds
Genotype: YY:Yy:yy
0:4:0
Phenotype: 4 Yellow: 0 green
100% yellow
If the variables like<em> </em><em>x </em>and <em>y </em>are used, their coefficients will still be 1920.
<h3>What is a coefficient?</h3>
A constant numerical expression, which is a part of the algebraic expression and mostly placed before variables, say <em>x </em>or <em>y, </em>is known as a coefficient of such variables.
Hence, the coefficients of 1920 are aforementioned.

For most university students, attending a four-year higher education institution means living at a place far from home. In this case, students must rent a place for them to stay, preferably, as near as possible to the university.
Generally, freshmen and sophomore students would choose to stay in a dormitory, which is also known as hall of residence for students of a university.
