Answer:

  3.347 N

Step-by-step explanation:

The vertical component of the dragging force is (120 N)/√2, so the net downward force is the difference between that due to gravity and the upward component of the dragging force.

  (9.8 m/s²)(9 kg) -(120 N)/√2 = 3.347 N

The normal force acting on the log is 3.347 N.

Answer:

$16.60

Step-by-step explanation:

4 x 0.85 = $3.40

20 - 3.40 = 16.6

Dave should get back $16.60 in change.

Answer:

$16.6 dollars back

Step-by-step explanation:

The answer is $16.6 because 0.85 times 4 is 3.4 and 20 minus 3.4 is 16.6

Answer:

[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

Step-by-step explanation:

Given the expression

[tex]a^3-b^3+4a-4b[/tex]

solving the expression

[tex]a^3-b^3+4a-4b[/tex]

as

[tex]\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)[/tex]

[tex]a^3-b^3=\left(a-b\right)\left(a^2+ab+b^2\right)[/tex]

also

[tex]\mathrm{Factor\:out\:common\:term\:}4[/tex]

[tex]=4\left(a-b\right)[/tex]

so the expression becomes

[tex]=\left(a-b\right)\left(a^2+ab+b^2\right)+4\left(a-b\right)[/tex]

[tex]\mathrm{Factor\:out\:common\:term\:}\left(a-b\right)[/tex]

[tex]=\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

Therefore,

[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

Answer:

The slope of the line that passes through (10, 9) and (1, 1) will be:

Step-by-step explanation:

Given the points

The slope between (10, 9) and (1, 1) is given by

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(10,\:9\right),\:\left(x_2,\:y_2\right)=\left(1,\:1\right)[/tex]

[tex]m=\frac{1-9}{1-10}[/tex]

[tex]m=\frac{8}{9}[/tex]

Thus, the slope of the line that passes through (10, 9) and (1, 1) will be:

Answer:

4x=x+18x=

We move all terms to the left:

4x-(x+18x)=0

We add all the numbers together, and all the variables

4x-(+19x)=0

We get rid of parentheses

4x-19x=0

We add all the numbers together, and all the variables

-15x=0

x=0/-15

x=0

Answer:

slope = 0

Step-by-step explanation:

(-3, 2) and (6, 2)

slope = (y1 - y2)/(x1 - x2)

remember, either x or y can be used but you have to be consistent

slope = (2-2)/(-3-6)

slope = 0/(-9)

slope = 0

Answer: no slope or 0

Step-by-step explanation:

The y-coordinates are the same for both points but the x coordinates are different. This signals a no-slope line, or a line where the slope is 0. Even if we apply the formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], it still ends up with 0.

Answer:

x>4

Step-by-step explanation:

Answer:

x = 35 degrees

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

Therefore, 48 + 97 + x = 180

Solve for x.

Thus, x = 180 - 48 - 97.

x = 35 degrees

Answer:

two

Step-by-step explanation:

If the discriminant of a quadratic equation is 12 then it has two distinct real roots. That 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.

Answer:

two

If the discriminant of a quadratic equation is 12 , then it has two distinct real roots. Note that 12 is not a perfect square, so if the coefficients of the quadratic are integers or otherwise rational, then the roots are both irrational.

Answer:

Below, you can see the graph of the function:

f(x) = x + cos(k*x)

for different values of k, as follows:

red: k = 1

green: k = 2

orange: k = 0.

Now let's find the values of k such that our function does not have local maxima nor local minima.

First, remember that for a given function f(x), the local maxima or minima points are related to the zeros of the first derivate of f(x).

This means that if:

f'(x0) = 0.

Then x0 is a maxima, minima or an inflection point.

Then if a function is such that the f'(x) ≠ 0 , ∀x, then this function will not have local maxima nor minima.

Now we have:

f(x) = x + cos(k*x)

then:

f'(x) = 1  - k*sin(k*x)

This function will be zero when:

1 = k*sin(k*x)

1/k = sin(k*x)

now, remember that -1 ≤ sin(θ) ≤ 1

then if 1/k is smaller than -1, or larger than 1, we will not have zeros.

And this will happen if -1 < k < 1.

Answer:

Step-by-step explanation:

Step one:

Given data

Force F= 10N

the distance is described by the coordinate =  (0,0) to (15,0)

hence the distance = 15m in the x-direction.

Step two:

Required is the work done

we know that work done is expressed as

Wd= Force* Distance

Wd= 10*15

Wd= 150 Joules

Answer:

Equations

Step-by-step explanation:

16:

7 · (-3) = -21

-3 · 7 = -21

-21 ÷ 7 = -3

-21 ÷ (-3) = 7

17:

-4 · (-5) = 20

-5 · (-4) = 20

20 ÷ (-4) = -5

20 ÷ (-5) = -4

18:

1.5 · (-3) = -4.5

-3 · 1.5 = -4.5

-4.5 ÷ 1.5 = -3

-4.5 ÷ (-3) = 1.5

This is 7th grade?

Hope I helped :)

Answer:

16. 7 x -3= -21

    -3 x 7= -21

    -21/-3=7

    -21/7=3

17. -4 x -5= 20

    -5 x -4= 20

    20/-4=-5

    20/-5=-4

18. 1.5 x -3= -4.5

   -3 x 1.5=-4.5

   -4.5/-3=1.5
