Answer:
A line that passes (2, 0) and (-6, 3) has slope:
S1 = (-6 -2)/(3 - 0) = -4/3
Another line that is perpendicular with above line has slope:
S2 = -1/S1 = -1/(-4/3) = 3/4
=> Option B is correct
Hope this helps

Answer:
It's Option A.
Step-by-step explanation:
Using the Cosine Rule:
cos < K = (3.9^2 - 1.9^2 - 2.8^2) / (-2 *1.9*2.8)
= 3.76 / -10.64
= - 0.3534.
m < K = 110.7 degrees.
Using the Sine Rule:
3.9 / sin 110.7 = 2.8 / sin <J
sin J = 2.8 sin 110.7/ 3.9 = 0.6716
m < J = 42.2 degrees
So m < L = 180 - (110.7 + 42.2)
= 180 - 152.9
= 27.1 degrees
Answer:
y = 3.5X - 6921.2
Step-by-step explanation:
Given the data :
X :
1990
1992
1994
1996
1996
Y :
45
51
57
61
75
Using an online regression calculator ; the regression model obtained is : y = 3.5X - 6921.2
Where ; slope = 3.5 ; intercept = - 6921.2
Answer: x = No solution
Step-by-step explanation:
Answer:
$58,000
Step-by-step explanation:
To solve this problem we first find cost of 1 blouse
then find cost of 2000 blouses.
cost of 1900 blouses = $55,100
to find cost of 1 blouse , divide both LHS and RHS by 1900
cost of 1900/1900 blouses = $55,100/1900 = $29
cost of 1 blouse = $29
to find cost of 2000 blouses, multiply both side by 2000
cost of 1*2000 blouse = $29*2000 = $58,000
Thus, cost of 2000 blouses will be $58,000.
