Answer:
1, A vertical stretch of 1/2
Step-by-step explanation:
As they y-values, or the vertical values, are being reduced by a factor of
<span>According to trigonometric the formula for sin is
sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3
Hence the answer is around 0.38
The result is Angle2..</span>
Answer:
x=7
Step-by-step explanation:
This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:
6x-7=4x+7
From there you can solve for x. I will write my process here:
2x-7=7
2x=14
x=7
Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!
Answer:
k = 0.0916
Step-by-step explanation:
T(t) =
from question; t = 12 mins , = 50 C , = 80 C , T = 60 C
60 = 50 + (80 - 50)
60-50 = 30
10/30 = (Taking natural Log of both sides)
In(0.3333) = In
-1.0986 = -12k
k = 0.0916
