Answer:
? = 57
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos ? = adj/ hyp
cos ? = 14/26
Taking the inverse cos of each side
cos ^-1 ( cos ?) = cos ^-1 ( 14/26)
? = 57.42102961
To the nearest degree
? = 57

Answer:
-81t^2 +16
Step-by-step explanation:
(9t-4)(-9t-4)
FOIL
first: -9t*9t = -81t^2
outer : -4*9t = -36t
inner : -4 *-9t = 46t
last = -4*-4 = 16
Add them together
-81t^2 -36t+36t+16
-81t^2 +16

Mikey's results showed that although both mice gained weight over the
month, mouse 2 gained more weight than mouse 1.Which graph below best
shows these results?
The complete figure is attached
=========================================================
Solution:
---------------
Graph (1)⇒⇒⇒ mouse 2 has constant weight and mouse 1 gained weight
Graph (3)⇒⇒⇒ mouse 2 has did not gain weight and mouse 1 gained weight
∴ Graph (1) and (3) are incorrect because both mice gained weight .
Graph (4) is incorrect because mouse 2 gained more weight than mouse 1
So, the correct answer is graph (2)
