Solve for x<br> -1/5(×-4)=-2<br><br> Enter your answer in the box.<br> ×=
Arisa [49]

Answer:

x = 14

Step-by-step explanation:

-1/5(x - 4) = -2

-1/5x + 4/5 = -2

-1/5x = -2 - 4/5

-1/5x = -10/5 - 4/5

-1/5x = - 14/5

x = -14/5 * - 5

x = 70/5

x = 14 <====

Shawn uses 45N of force to stop the cart 1 meter from running his foot over. How much work does he do?​
zalisa [80]

Answer:

\boxed {\boxed {\sf 45 \ Joules}}

Step-by-step explanation:

Work can be found by multiplying the force by the distance traveled in the direction of the force.

W=F*d

The force is 45 Newtons.

The distance traveled is 1 meter.

F=45 \ N \\d= 1 \ m

Substitute the values into the formula.

W=45 \ N * 1 \ m

Multiply.

W=45 \ N*m

1 Newton meter is equal to 1 Joules.

Therefore our answer of 45 Newton meters is equal to 45 Joules.

W= 45 \ J

The work done is <u>45 Joules.</u>

1. Suppose that cos B = 0.68. What is the value of sin(a)? Explain.
Papessa [141]

The value of Sin(a) suppose that Cos B = 0.68 in which case, a + B = 90° is; 0.68.

<h3>Trigonometry</h3>

First, when we have two angles, whose sum equals, 90°.

In essence, Since the algebraic sum of angles A and B is 90°;

  • A + B = 90.

  • B = 90 -A.

By trigonometric identity;

  • Sin A = Cos (90 - A)

Where; (90 - A) = B.

Therefore; Sin A = Cos B = 0.68.
