Answer 1
Answer:

Answer:

13892 lb-ft/sec^2

Step-by-step explanation:

Given that An auto weighing 2,500 pounds is on a street inclined at 10 with the horizontal.

Here acceleration due to gravity is the pulling factor against which the car should be stopped from rolling down the hill.

Weight of the car =2500 pounds

Vertical component of gravity = 32cos (90-10)=32sin 10 = 32(0.1736)

Force required = mass x acceleration

=2500x0.1736x32

=13892 lb ft/sec^2
Answer 2
Answer: Make sure your calculator is set to DEGREES and not RADIANS when performing your sinθ calculation. sin(10) = -0.54402 sin(10°) = 0.17365 You could also try using trig tables if you're unsure how to do this. So: 2500sin(10°) = 434 lb

For the system of equations shown below2x = −y + 6
−4x + 3y = 8
What is the solution to the system of equations?

Answers

2x=-y+6
-4x+3y=8
Rewriting the equations;
y+2x=6
3y-4x=8

Multiplying equation I by 3;
3y+6x=18
3y-4x=8
Subtracting equation II from equation I;
10x=10
x=1

Replacing for x in the first equation;
2x=-y+6
2(1)=-y+6
2=-y+6
2-6=-y
-4=-y
y=4

Michi put $7.50 worth of gas in her car. two co-workers who were riding to work with her offered to share the cost of the gas. one paid 1/2 of the total amount and the other paid 1/3 of the total amount. how much of the total amount was left

Answers

1.25.
7.50 x 1/2 = 3.75
+
7.50 x 1/3 = 2.50
= 6.25
7.50 - 6.25 = 1.25

Find the coordinates of the intersection of the diagonalsof parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2). Hint: what do we know about
the diagonals of a parallelogram?

Answers

The coordinates of the intersection of the diagonals  of parallelogram XYZW is at (6, 4).

Parallelogram

A parallelogram is a quadrilateral in which opposite sides are parallel and equal. The diagonals of a parallelogram bisect each other.

Given parallelogram XYZW with vertices X(2, 2), Y(3, 6), Z(10, 6), and W(9,2).

The equation of diagonal XZ is:

  • y-2=(6-2)/(10-2) (x-2)\n\ny=0.5x+1

The equation of diagonal YW is:

  • y-6=(2-6)/(9-3) (x-3)\n\ny=-(2)/(3) x+8

The point of intersection is at:

0.5x + 1 = (-2/3)x + 8

x = 6. Hence y = 4

The coordinates of the intersection of the diagonals  of parallelogram XYZW is at (6, 4).
