Answer:
a
Step-by-step explanation:
sec (thita) = squrt (5)
squaring on both sides:
sec^2 (thita) = 5 - equation 1
1 + tan^2 (thita) = 5
tan^2 (thita) = 4
tan (thita) = 2.
= tan (thita) - squrt(5)sin(thita)
= 2 - squrt(5) x 2/ squrt(5)
= 0
from eqn - 1
sec(thita) = squrt(5)
cos(thita) = 1/ squrt(5)
sin(thita) = squrt ( 1- 1/(squrt (5))^2)
sin(thita) = 2/ squrt(5) .
√3=1.7
2√3=3.4
√5=2.2
The order:
√3,2√3,√5
Answer:
Point Q = (3.6, 1.4)
Step-by-step explanation:
The 4:1 ratio should first be changed to 4/5.
y2-y1= 2+1 = 3 which as a fraction is 3/1, now multiply that which the earlier fraction 4/5 to get 12/5 = 2.4
x2-x1= 4-2= 2 which as a fraction is 2/1, do the same as earlier, multiply by 4/5 to get 8/5 = 1.6
now add these to A to get point Q
2+1.6= 3.6
-1+2.4=1.4
Point Q = (3.6, 1.4)
Answer:
y = 2x + 1
Step-by-step explanation:
When given a point and a slope, use point-slope form of a line.
y - y₁ = m (x - x₁)
Here, (x₁, y₁) is (1, 3), and m = 2.
y - 3 = 2 (x - 1)
We can convert to slope-intercept form by solving for y:
y - 3 = 2x - 2
y = 2x + 1
