Step-by-step explanation:

$\sf Required\:Answer\begin{cases} \sf Force_(f)=45N \\ \sf Distance_(d)=1m \\ \sf As\:we\:know\:that \\ {\boxed{\sf Work_(w)=Force_(f)\times Distance_(d)}} \\ \sf W=45 \times 1Nm \\ \sf =45Nm \\ \longrightarrow {\underline{\boxed{\bf W=45Joule}}}\end {array}$

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 45 Joules.

What are the coordinates of the point on the directed line segment from

Zielflug [23.3K]

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n

Then using the Section formula the coordinates of the point are

( $\frac{nx_{1}+mx_{2} }{m+n}$ , $\frac{ny_{1}+my_{2} }{m+n}$ )

Here (x₁, y₁ ) = (- 4, - 9), (x₂, y₂ ) = (1, 1) and m : n = 3 : 2 , then

( $\frac{2(-4)+3(1)}{3+2}$ , $\frac{2(-9)+3(1)}{3+2}$ )

= ( $\frac{x}{y} \frac{-8+3}{5}$ , $\frac{-18+3}{5}$ )

= ( $\frac{-5}{5}$ , $\frac{-15}{5}$ )

= ( - 1, - 3 )

HELP PLEASE -9x + 3 > 39 OR - 5x + 6 < 16

Mama L [17]

Answer:

(-∞, -4) ∪ [-2, ∞)

Step-by-step explanation:

The solution to the first inequality is ...

-9x +3 > 39

-9x > 36 . . . . . subtract 3 from both sides

x < -4 . . . . . . . divide both sides by -9; reverse > to < because -9 is negative

The solution to the second inequality is ...

-5x +6 ≤ 16

-5x ≤ 10 . . . . . . . subtract 6 from both sides

x ≥ -2 . . . . . . divide both sides by -2; reverse ≤ to ≥ because -2 is negative

These solution sets are disjoint. The solution of the OR of these inequalities is the union of the solution sets. The graph is shown below. In interval notation, it is described by ...

(-∞, -4) ∪ [-2, ∞)

The -2 has a square bracket because it is included in the set. The curved bracket at -4 indicates it is not included.
