I'll gladly help you, but I can't really read that.

Q=p(r+s) solve for p

pav-90 [236]

Q = p(r+s)
--------------
(r+s) (r+s) Divide both sides by (r+s) so you can get the p bu itself this way you get q / (r+s) = p

Answer: $(-1.412,-2.124),(3.29,7.28)$

Step-by-step explanation:

Given

The given equation is $2^x-2.5=2x+0.7$

There are two functions i.e. $y=2^x-2.5\ \text{and}\ y=2x+0.7$

Their intersection gives the solution of the above function

From the graph, we can see that both the graph intersects at two different points i.e. at

$(-1.412,-2.124)\ \text{and}\ (3.29,7.28)$

three trigonometric functions for a given angle are shown below csc theta = 13/12, sec theta = -13/5, cot theta = -5/12 what are

goldenfox [79]

We have that
csc ∅=13/12
sec ∅=-13/5
cot ∅=-5/12

we know that
csc ∅=1/sin ∅
sin ∅=1/ csc ∅------> sin ∅=12/13

sec ∅=-13/5
sec ∅=1/cos ∅
cos ∅=1/sec ∅------> cos ∅=-5/13

sin ∅ is positive and cos ∅ is negative
so
∅ belong to the II quadrant

therefore
<span>the coordinates of point (x,y) on the terminal ray of angle theta are
</span>x=-5
y=12

the answer is
point (-5,12)

see the attached figure
