Answer:

Step-by-step explanation:

x² + 6x = 8

Coefficient of the x term: 6

Divide it in half: 3

Square it: 3²

Add 3² to both sides of the equation to complete the square and keep the equation balanced:

x² + 6x + 3² = 8 + 3²

(x+3)² = 17

I just answered this.... :]

x - 0.05x = 57,
0.95x = 57,
57/0.95 = original price
Original price = $60

The vector parametric equation for the line through the points (−1,−4,2) and (−1,0,−3) is:_______

ollegr [7]

Answer: $x(t)=-1$

$y(t)=-4+4(t)$

$z(t)=2-5(t)$

Step-by-step explanation:

To find: The vector parametric equations for the line through the points (−1,−4,2) and (−1,0,−3).

Let A (−1,−4,2) and B(−1,0,−3)

First we find direction vectors : $\overrightarrow{AB}=$

Now, the parametric equations of the line:

$x(t)=-1+0(t)$

$y(t)=-4+4(t)$

$z(t)=2-5(t)$

Hence, the vector parametric equations for the line through the points (−1,−4,2) and (−1,0,−3):

$x(t)=-1$

$y(t)=-4+4(t)$

$z(t)=2-5(t)$

Math question NO Guessing Please Help

The angle of interest is the one at the end of the shadow looking up toward the flagpole. Thus the length adjacent to the angle is that of the shadow, 22 ft. The length opposite the angle is the height of the flagpole, 45 ft. The tangent of the angle is the ratio of the opposite length to the adjacent one.

... tan(angle) = (45 ft)/(22 ft)

... angle = arctan(45/22) ≈ 63.9° . . . . . matches selection A.
