19, find the direction angle of vector v to the nearest tenth of a degree

labwork [276]

The vector v is given by:
v = (7, 2) - (-5, 0)
v = ((7 - (- 5)), (2-0))
v = ((7 + 5), 2)
v = (12, 2)
Then, the angle is given by:
tan (theta) = 2/12
theta = atan (2/12)
theta = 9.46 degrees
Answer:
The direction angle of vector to the nearest tenth of a degree is:
theta = 9.5 degrees

Estimate the area of a circle with a radius of 21 meters. Use 22/7 for pi. (1 point)

V125BC [204]

A= $\pi$ $r^{2}$

A=( $\frac{22}{7}$ )( $21^{2}$ )

A=( $\frac{22}{7}$ )(441)

A= $\frac{22}{7}$ )( $\frac{441}{1}$ )

A= $\frac{9702}{7}$

A=1386 square meters

The answer is B.

Evaluate the function at the given values F(y) = 4y^4 - 6y^2 + 8y - 15 At y = 2

otez555 [7]

F(2)= 4(16) - 6(4) + 8(2) - 15
F(2)= 64 -24 + 16 - 15
F(2)= 41

Write an equation or system of equations to solve the problem below.

VashaNatasha [74]

Equations:

2x+105=-3x+130

subtract 2x from both sides 

105= -5x+130

Subtract 130 from both sides

-5x= -25

isolate the variable

x=5 

Plug back in

2(5)+105= -3(5)+130

115= 115
