I'm not sure how to write the rule, but every time you add one more to the sum of the last two. First, you add 1, then 2, then 3. 1+1=2 2+2=4 4+3=7 7+4=11 and so on. I hope this helps!

F=5/4(n-90)<br> Find n <br> Helppp
padilas [110]

Answer:

n= 4f/5+90

Step-by-step explanation:

f=  ​5(n−90) /4 (simplify)

f * 4=5(n−90)  (multiply 4 on both sides)

4f=5(n−90)  (regroup)

4f/5 ​​ =n−90 (divide 5 on both sides)

4f/5 ​​ +90=n  (add 90 to both sides)

Which statement regarding the function y=cos(x) is true?
MAVERICK [17]
<span>A. cos(x) = cos(-x)  [correct, since cos(x) is an even function]
B. Since the cosine function is even, reflection over the x-axis [y-axis] does not change the graph.  [false]
C. cos(x) = -cos(x)   [ false]
D. The cosine function is odd [even], so it is symmetrical across the origin.   [false]</span>

Choose the equation of the horizontal line that passes through the part point (1,-5)
vladimir2022 [97]
We know is a horizontal line, so, if it passes through 1,-5, it also passes through "whatever", -5, like 20, -5 or 1000000, -5, or -100000000, -5 and so on.

so, let's pick another point say -7, -5, check the picture below, and let's check about the equation that runs through it,

\bf \begin{array}{ccccccccc}&#10;&&x_1&&y_1&&x_2&&y_2\\&#10;%  (a,b)&#10;&&(~ 1 &,& -5~) &#10;%  (c,d)&#10;&&(~ -7 &,& -5~)&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies &#10;\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-5-(-5)}{-7-1}&#10;\\\\\\&#10;\cfrac{-5+5}{-7-1}\implies \cfrac{0}{-8}\implies 0&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-5)=0(x-1)&#10;\\\\\\&#10;y+5=0\implies y=-5
