Answer:
y= 17
Step-by-step explanation:
First one
20=n/5+10
minus 10 both sides
10=n/5
times 5 both sides
50=n
2.
hmm
expand
p(x)=2x^2+5x+3-3x-3n
p(x)=2x^2+2x+3-3n
it looks like the coefients of the x terms are divisble by 2
because
if we have
p(x)=2(something)
the p(x) is divisible by 2
therefor that factor is 2 or -2
find what value of n works
so
3-3n=a multipule of 2
we are given
-3,-2,0,2
try each
3-3(-3)=3+9=12, that's divisble by 2
3-3(-2)=3+6=9, that's not divisible by 2
3-3(0)=3, that's not divisble by 2
3-3(2)=3-6=3, that's not divisble by 2
the onnly one that woks is when n=-3
answer is A
Make a drawing of the situation:
Recalling the tangent trigonometric relationship, if the angle of inclination is A, then:
Use the inverse tangent function to find the value of A:
Use a calculator to find the numerical value of the inverse tangent of 6:
Therefore, the angle of inclination of the Sun is approximately 80.5°.
Answer:
x=18.25
Step-by-step explanation:
the square has to have a 90 degress angle so 4x+17=90
4x + 17 = 90
-17 -17
--------------------
4x = 73
and once you do 73/4 you get 18.25 so
<h2>x = 18.25</h2>
