If a force F⃗ acts on an object as that object moves through a displacement s⃗ , the work done by that force equals the scalar p

roduct of F⃗ and s⃗ : W=F⃗ ⋅s⃗ . A certain object moves through displacement s⃗ =(4.00m)i^+(5.00m)j^. As it moves it is acted on by force F⃗ , which has x-component Fx = -12.0 N (1 N = 1 newton is the SI unit of force). The work done by this force is 26.0 N⋅m = 26.0 J (1 J = 1 joule = 1 newton-meter is the SI unit of work). Find the y-component of F⃗ .

Answer:

Fy=14.8N

Step-by-step explanation:

the dot product between \vec{F} \\ and \vec{S}

is given by:

W=\vec{F}\cdot\vec{S}= S_xF_x+SyFy

this gives the equation :

26= (4.00)(-12.0)+(5.00)Fy

26= -48+(5.00)Fy

adding 48 to both sides of the equation:

74= (5.00)Fy

dividing by 5, we get

Fy=74/5.00=14.8

zubka84 [21]

Answer:

x   f(x)   g(x)

1    15    3

2    16   4

3    15    5

4    12    6

5    7     7

6    0     8

f(x) = g(x) when x = 5

Step-by-step explanation:

f(x) = -x² + 4x + 12

f(1) = -(1)² + 4(1) + 12 = 15

f(2) = -(2)² + 4(2) + 12 = 16

f(3) = -(3)² + 4(3) + 12 = 15

f(4) = -(4)² + 4(4) + 12 = 12

f(5) = -(5)² + 4(5) + 12 = 7

f(6) = -(6)² + 4(6) + 12 = 0

g(x) = x + 2

g(1) = 1 + 2 = 3

g(2) = 2 + 2 = 4

g(3) = 3 + 2 = 5

g(4) = 4 + 2 = 6

g(5) = 5 + 2 = 7

g(6) = 6 + 2 = 8

As part of a new fitness plan, Sabir walks on a treadmill at the same speed for 15 minuets every morning. The table shows the ca
Reil [10]
The relationship between Sabir and calories he burns can be modeled using a linear function given by:
y=ax+b
where
a=slope
b=y-intercept
from the graph, the slope will be given as follows:
taking points (3,15) and (12,60)
a=(60-15)/(12-3)=5 calories/minute
thus using the slope and a point (3,15) the equation will be:
a(x1-x)=(y1-y)
plugging the values we obtain:
5(x-3)=y-15
5x-15=y-15
thus
y=5x
thus the equation is:
y=5x

What is the average rate of change for 5/6 and 15/14
andreev551 [17]

Answer:

Average rate of change is <u>0.80.</u>

Step-by-step explanation:

Given:

The two points given are (5, 6) and (15, 14).

Average rate of change is the ratio of the overall change in 'y' and overall change in 'x'. If the overall change in 'y' is positive with 'x', then average rate of change is also positive and vice-versa.

The average rate of change for two points (x_1,y_1)\ and\ (x_2,y_2) is given as:

R=\frac{y_2-y_1}{x_2-x_1}

Plug in x_1=5,x_2=15,y_1=6,y_2=14 and solve for 'R'. This gives,

R= \frac{14-6}{15-5}\\\\R=\frac{8}{10}\\\\R=0.80

Therefore, the average rate of change for the points (5, 6) and (15, 14) is 0.80.

PLZ HELP ME WITH MY MATH HOMEWORK!!!!!! SHOW WORK
nadya68 [22]

Answer:

Step-by-step explanation:

       -(4q+8) + 6q = 12q - 5/6(18q + 6)

Open brackets:

<=>  - 4q - 8 + 6q = 12q - 5/6*18q - 5/6*6

<=>  - 4q - 8 + 6q = 12q - 15q - 5

Put q in one side and non q in one side:

<=> - 4q + 6q - 12q + 15q = 8 - 5

<=> 5q = 3

<=> q = 3/5
