Write an expression in simplest form for the area of the rectangle.
Length: (c+4) ft
Width: 3 ft

Answers

Answer:

3c+12

Step-by-step explanation:

Are of rectangle = Length * Width

Given the following data

Length: (c+4) ft

Width: 3 ft

Area of the rectangle = 3 (c+4)

Expand

Area of the rectangle = 3(c) + 3(4)

Area of the rectangle = 3c  + 12

hence the expression in simplest form for the area of the rectangle is 3c+12

Newton's Law of Motions

Newton's 1st Law of Motion: An object at rest remains at rest and an object in motion stays in motion Newton's 2nd Law of Motion: F = ma (Force is equal to [constant] mass times acceleration) Newton's 3rd Law of Motion: For every action, there is an equal and opposite reaction Step-by-step explanation:

Step 1: Define

[Given] F = 20.0 N

[Given] a = 5.0 m/s²

[Solve] Mass m

Step 2: Solve for m

Substitute in variables [Newton's 2nd Law of Motion]:                               20.0 N = m(5.0 m/s²)[Division Property of Equality] Divide 5.0 on both sides:                            4.00 kg = mRewrite:                                                                                                           m = 4.00 kg

Find the equation of a line that passes through the point (3,1) and has a gradient of -3. Leave your answer in the form y = m x + c

Answers

Answer:

[tex]y = (-3)\, x + 10[/tex].

Step-by-step explanation:

The question requires that the equation should be in the slope-intercept form [tex]y = m \, x + c[/tex]. The [tex]m[/tex] and [tex]c[/tex] in this equation are constants. In particular:

[tex]m\![/tex] would represent the slope of this line (also known as the gradient of this line,) whereas[tex]c[/tex] would be the [tex]y[/tex]-intercept of this line.

The question states that the slope of this line is [tex](-3)[/tex]. Therefore, [tex]m = -3[/tex]. Thus, the equation for this line should be in the form [tex]y = (-3)\, x + c[/tex].

The value of constant [tex]c[/tex] could be found using the other piece of information: the point [tex](3,\, 1)[/tex] is in this line. In other words, the solution [tex]\text{$x = 3$ and $y = 1$}[/tex] should satisfy the equation [tex]y = (-3)\, x + c[/tex].

Substitute [tex]\text{$x = 3$ and $y = 1$}[/tex] into the equation [tex]y = (-3)\, x + c[/tex] and solve for [tex]c[/tex]:

[tex]1 = (-3) \times 3 + c[/tex].

[tex]1 = -9 + c[/tex].

[tex]c = 10[/tex].

Hence, [tex]y = (-3) \, x + 10[/tex] would be the slope-intercept form of the equation of this line.

Answer:

n = √3

m = √3

Step-by-step explanation:

The triangle is an isosceles right triangle with 2 equal base angles of 45° each.

Thus:

Reference angle = 45°

Hypotenuse = √6

Opposite = m

Adjacent = n

✔️To find m, apply the trigonometric function SOH, we have:

Sin 45 = opp/hyp

Sin 45 = m/√6

√6 × 1/√2 = m (sin 45 = 1/√2)

√6/√2 = m

√(6/2) = m

√3 = m

m = √3

✔️To find n, apply the trigonometric function, CAH:

Cos 45 = adj/hyp

Cos 45 = n/√6

√6 × √2/2 = n (cos 45 = √2/2)

√12/2 = n

√(4*3)/2 = n

(2√3)/2 = n

√3 = n

n = √3

Answer:

Step-by-step explanation:

The slope intercept form of a line is y=mx+b where m=slope and b=y intercept. So we should solve for y.

3x/5+25y=10, multiply all terms by 5 and the denominator cancels out

3x+125y=50, subtract 3x from each side

125y=-3x+50, divide both sides by 125

y=(-3+50)/125

slope=m=-3/125

y intercept=b=2/5

B: This is INCORRECT because Fabric B lasted longer than Fabric A

C: This is CORRECT because Fabric B is medium duty fabric

D:This is CORRECT because Fabric B lasted more rubs than Fabric A because its a more durable fabric

Is the following relation graphed below a function? Explain? Think about what open and closed circles mean

Answers

Given:

The graph of a relation.

To find:

Whether the given relation in the graph is a function or not.

Solution:

First we need to understand the meaning of open circles and closed circles.

Open circle: It is a unfilled circle, it means, that value is not included in the solution set.

Close circle: It is a completely filled circle, it means, that value is included in the solution set.

A relation is a function if their exist a unique y-value (output value) for each x-value (input value).

The graph of a relation is a function, if the graph intersect each vertical line at most once. It is known as vertical line test.

For the vertical lines x=-1 and x=1, the graph has only one close circle and all other vertical line intersect the graph at most once.

Since the graph passes the vertical line test, therefore it represents a function.
