Answer:
x=2π/3+π n
Step-by-step explanation:
Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.
Answer:
The reasonable estimate for the solution is (2.29, -4.87)
Step-by-step explanation:
The reasonable estimate for the solution is the point where the two lines intersect each other.
To get the point where they intersect, we will simply equate the system of equations given as shown:

Substitute x = 2.29 into any of the equation
Using the equation y = -3x+2
y = -3(2.29)+2
y = -6.87+2
y =-4.87
This shows that the reasonable estimate for the solution is (2.29, -4.87)

Answer:
Option C. No, because the two populations from which the samples are selected do not appear to have equal variances.
Step-by-step explanation:
The variance measures how far a set of (random) numbers are spread out from their average value.
The fact that the younger adults show diversity in their brain activity while the older adults produce similar activities show that there are no equal variances in the two populations from which the samples are selected.
Therefore it would not be valid for Dr. Park to use the independent-measures t-test to test whether the brain activity of younger adults is different from that of older adults during a visual recognition task
Answer:
gradient 1/2, y-intercept 9
Step-by-step exp
Step-by-step explanation:
The expressions are not properly written
Given
RS = 4x – 9
ST = 19
RT = 8x – 14
Based on the given parameters, the addition postulate below is true
RS+ST = RT
Substitute
4x-9+19 = 8x-14
collect like terms
4x-8x = -14-19+9
-4x = -33+9
-4x = -24
x = -24/-4
x = 6
Get RS:
RS = 4x-9
RS = 4(6)- 9
RS = 24-9
RS = 15
Get RT:
RT = 8x - 14
RT = 8(6)-14
RT = 48-14
RT = 34
