Answer:
IJ is 5.8 ft
Step-by-step explanation:
Here, we want to calculate the length of IJ
to Find IJ, we need the appropriate trigonometric ratio
The trigonometric ratio to use in this case is the one that connects the opposite and the adjacent
from the question, IJ is the opposite
This is the side facing the given angle
HI is the hypotenuse which is the side facing the right-angle
HJ is the third side which is the adjacent
Mathematically;
That is the Tan
Tan 71 = IJ/2
IJ = 2 Tan 71
IJ = 5.8
Answer:
The change in temperature from last week to this week=3.5
Step-by-step explanation:
To get the change in temperature from last week to this week, we need to take last week's temperature and subtract it from this week's temperature.
For example;
Change in temperature=This week's temperature-last week's temperature
where;
This week's temperature=-2.25
last week's temperature=1.25
replacing;
Change in temperature=(1.25)-(-2.25)=1.25+2.25=3.5
The change in temperature from last week to this week=3.5
Five fifths are in one whole.
Don't believe me?
So you just do 1÷5
which is 5!

V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a
r=3
h=2a
v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ
so the expression would be some variaant of v=6aπ
