Answer: 109.1 degrees
Step-by-step explanation:
To find the angle between the given vectors, we will use the formula below:
Cos(θ) = (U.V)/ |U|.|V|
Where
U = 13i - 8j
V = 2i + 9j
U.V = (2x13) + (-8×9)
U.V = 26 - 72
U.V = - 46
|U| = sqrt ( 13^2 + 8^2)
= sqrt ( 233) = 15.264
|V| = sqrt( 2^2 + 9^2)
= sqrt ( 85 ) = 9.22
Substitute all the value of the parameters into the formula
Cos ø = -46 / (15.3 × 9.2)
Cos ø = - 46 / 140.72
Cos Ø = - 32687
Find the cos inverse of the value
Ø = cos^-1( -32687)
Ø = 109.079 degrees
Therefore, the angle between the given vectors to the nearest tenth of a degree is 109.1 degrees

This question is false, there are no solutions, even if u take away the x and make it multiplication instead of a variable, still no solutions exist
Answer:
The center is (0,0) and the radius is 4
Step-by-step explanation:
x^2+y^2=16.
The equation of a circle can be written in the form
(x-h)^2+(y-k)^2=r^2 where ( h,k) is the center and r is the radius
(x-0)^2+(y-0)^2=4^2
The center is (0,0) and the radius is 4
