Joshua used two wood beams, PC and QA, to support the roof of a model house.
Mazyrski [523]

Answer:

\boxed{\boxed{PQ=3.6\ in}}

Step-by-step explanation:

As it is given as ΔQRP and ΔARC are similar, so the ratio of their corresponding sides will be same.

So,

\dfrac{RC}{PR}=\dfrac{AC}{PQ}

It is given as,

RC  = 3.3

PR = 1.8

AC = 6.6

PQ = ??

Putting the values,

\Rightarrow \dfrac{3.3}{1.8}=\dfrac{6.6}{PQ}

\Rightarrow PQ=\dfrac{6.6\times 1.8}{3.3}=3.6

At what width does a totality of a Solar Eclipse span?
I am Lyosha [343]
I think you're talking about the black spot on the surface of the Earth,
where the end of the Moon's shadow falls, and anybody inside that
circle sees the Sun completely covered for a few minutes.

The size of that spot varies.  It depends on exactly how far the Moon
is from the Earth, and exactly how far both bodies are from the Sun.

The longest possible totality viewed from a single location is about
7-1/2 minutes, when all the geometry is just right.  Then, I believe,
the black spot on the Earth's surface is something like 170 miles
across, moving at around 24 miles a minute, or  1,460 miles per hour.

HELP! (Urgent pre-calculus question.)
marishachu [46]
2. means that for every x, there is eactly one y
basically, we can use the vertical line test to see if it crosses at any 2 points

first one works
2nd one works
3rd works
4th works
5th works
they are all one to one functions



3.
easy
steps
for f(x)=?
replace f(x) with y
switch x and y
solve for y
replace y with  f⁻¹(x)
so

f(x)=(1+x)^3-2
replace
y=(1+x)^3-2
switch
x=(1+y)^3-2
solve
x+2=(1+y)^3
\sqrt[3]{x+2}=1+y
-1+\sqrt[3]{x+2}=
replace
f^{-1}(x)=-1+\sqrt[3]{x+2}
first option



4.
domain, hmm we can't divide by 0 so domain is all real numbers except for x=0
domain is (-\infty,0) \cup(0,\infty)
hmm, range
as x approaches negative or positive infinity, f(x)=5
as x approaches 0 from the left, f(x) appraoches negative infintiy
as x approaches 0 from the right , f(x) appraoches positive infintiy
so range is (-\infty,5) \cup(5,\infty)

domain is (-\infty,0) \cup(0,\infty)
range is (-\infty,5) \cup(5,\infty)
answer is the 4th option
