How do you think you could simplify f(x) + g(x) if f(x) = 3x + 2 and g(x) = 4x?

Answers

Step-by-step explanation:

f(x) = 3x + 2

g(x) = 4x

= f(x) + g(x)

= 3x + 2 + 4x

= (3 + 4)x + 2

= 7x + 2

(f+g)(x) = 7x + 2

Inclined Ramp A 2-pound weight is attached to a 3-pound
weight by a rope that passes over an ideal pulley. The smaller
weight hangs vertically, while the larger weight sits on a
frictionless inclined ramp with angle 0. The rope exerts a
tension force T on both weights along the direction of the
rope. Find the angle measure for that is needed to keep
the larger weight from sliding down the ramp. Round your
answer to the nearest tenth of a degree.

The angle measure for the inclined ramp needed to keep the larger weight from sliding down the ramp is 42⁰.

The given parameters;

mass of the small block, m = 2 lb = 0.91 kgmass of the larger block, = M = 3 lb = 1.36 kg

The normal force on the larger weight (3 lb) is calculate as;

[tex]F_n = Mgcos(\theta)[/tex]

The net force on the larger weight is calculated as;

[tex]Mgsin(\theta) - T = 0[/tex]

where;

T is the tension on the wire due to the smaller weight pulling up the 3 lb weight.

T = mg

[tex]Mgsin(\theta) - mg = 0\\\\(1.36\times 9.8)sin\theta \ - \ (0.91 \times 9.8) = 0\\\\13.328 sin(\theta) = 8.918\\\\sin(\theta) = \frac{8.918}{13.328} \\\\sin(\theta) = 0.669\\\\\theta = sin^{-1} (0.669)\\\\\theta = 42\ ^0[/tex]

Thus, the angle measure for the inclined ramp needed to keep the larger weight from sliding down the ramp is 42⁰.

if you have 3 pounds of apples and they cost 12$ whats the unit price

Answers

Answer:

unit price = 4$ a pound

Step-by-step explanation:

3 pounds for a total of 12$, but you need to know the price of 1 individul unit, so within those 3 lbs is 3 "individul units" (aka 1 pound)

total cost = 12$ for all 3 units so divide 12 by 3 (12/3) = 4  --> Giving you the cost of 1 unit  which is $4.00

Check you work : 3 units (3lbs) , you know 1 unit(pound) costs 4$ and your total you paid needs to be equal to 12$

SO: 3 (your pounds) x 4 (price PER unit) = 12  

12 = 12

Describe the graph of the equation Y equals 6X

Answers

Answer:

Make a line using points (0,0) (1,6) and (-1,-6)

Step-by-step explanation:

Okay, so your first point will be (0,0) at the origin because in your equation there is no y-intercept.

For your next point, we have to use Rise/Run, or slope, to find our next point. In y=mx+b, m is the slope. So for y=6x, 6/1 is our slope.

So from the origin, we go up 6 and to the right once. This will give us the point (1,6)

Incase you need another point, we can also go down 6 and left 1. This gives us the point (-1,-6)

Answer:

1. 452.16 square centimeters

2. 150.72 square centimeters

3. 25.12 centimeters

Step-by-step explanation:

1. the area of the circle

The area of a circle can be calculated with:

[tex]a=\pi r^2[/tex]

The area of the given circle then, is:

[tex]a=\pi 12^2\\a=144\pi\\[/tex]

or just 452.16 square centimeters.

2. the area of the minor sector

There's a convenient formula for this, but I don't remember it and you don't really need it. A full circle is 360°, and 120° is exactly 1 third of that. 1 third of the size means 1 third of the area:

[tex]a=452.16*\frac{1}{3} \\a=150.72[/tex]

or 150.72 square centimeters

3. the area of the minor arc

You can do the same thing here. The circumference of a circle is:

[tex]u=2\pi r[/tex]

So the circumference of the given circle is:

[tex]u=2\pi (12)\\u=24\pi[/tex]

or about 75.36 centimeters.

One third of that:

[tex]u=75.36*\frac{1}{3} \\u=25.12[/tex]

25.12 centimeters.

Answers

Answer:

Step-by-step explanation:

to find this all you need to do is find the cos per full uniform by adding 1.25m for the blouse and 1.35m for the skirt. This will equal 2.6m per full uniform. you need to then multiply this by 12 to find the total fabric needed for the 12 uniforms which will equal 31.2. you then multiply this answer by the 50 cents per meter to get the cost which will be $15.60

The vertex is (-3,0)

Step-by-step explanation:

Insert the values into the given equation on the assignment in order to get the coordinates of the vertex.

The values are:

a = 1

b = 6

c = 9

For the x coordinate, insert the a and b values into the equation (-b/2a):

-6/(2*1) =

-6/(2) =

-3

So now we know the x value is 3, to find the y value insert the a, b, and c values into the equation -(b^2-4ac)/4a

-(6^2 - (4*1*9))/(4*1) =

-(36-(36))/4 =

-0/4 =

0

So the y value is 0 and the vertex is (x,y), so the vertex is (-3,0)
