Answer:

3x+1

Step-by-step explanation:

you first have x(your unknown variable)

Then you multiply x by 3 to get 33x you write it like this because 3×x would be confusing.

After you have 3x you then need to add 1 and therefore your new equation is 3x+1

A rectangular prism has a volume of 378 cubic inches the area of the base is 42 square inches what is the height
barxatty [35]

Answer:

9 inches.

Step-by-step explanation:

The formula for the volume of a rectangular prism is base x height.  So if the volume is 378, and the base is 42, you would use the equation 378/42 to find the height. 378/42 is 9.  Therefore, the height is 9 inches.

boat

use Pythagorean Theorem to satisfy...a^2 + b^2 = c^2

200^2 + b^2 = 300^2
b^2 = 300^2 - 200^2
b^2 = 50000  (get square root of each)
b = 223.606  (rounded to the nearest tenth.... = 223.6

What us the difference in the ares of a circle with diameter 4 m and a circle with diameter 6 m? Round your answer to the neares
enyata [817]
Let's calculate each area.
4 m:
We need to divide it by 2 to find the radius.
4÷2=2
Now let's put it in the formula.
2²π
4π=12.5663706≈13
6 m:
We need to divide it by 2 for the radius.
6÷2=3
Now put it in the formula.
3²π
9π=28.2743≈28
Now subtract 13 from 28.
28-13=15
So, the difference between their area is 15 m².

Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry of this function:
Maslowich

Answer:

Part 1) The vertex is the point (1,-9)

Part 2) The equation of the axis of symmetry is x=1

Part 3) The y-intercept is the point (0,-8)

Part 4) The x-intercepts are (-2,0) and (4,0)

Part 5) The graph in the attached figure

Step-by-step explanation:

we have

h(x)=(x-1)^2-9

This is a vertical parabola open upward

The vertex represent a minimum

Part 1) Find the vertex

The quadratic equation is written in vertex form

y=a(x-h)^2+k

where

(h,k) is the vertex of the parabola

so

The vertex is the point (1,-9)

Part 2) Find the axis of symmetry

The equation of the axis of symmetry of a vertical parabola is equal the the x-coordinate of the vertex

so

The equation of the axis of symmetry is

x=1

Part 3) Find the y-intercept

we know that

The y-intercept is the value of the function when the value of x is equal to zero

so

For x=0

h(x)=(0-1)^2-9

h(0)=-8

therefore

The y-intercept is the point (0,-8)

Part 4) Find the x-intercepts

we know that

The x-intercepts are the values of x when the value of the function is equal to zero

so

For h(x)=0

(x-1)^2-9=0

solve for x

(x-1)^2=9

square root both sides

x-1=\pm3

x=1\pm3

x=1+3=4\\x=1-3=-2

therefore

The x-intercepts are (-2,0) and (4,0)

Part 5) Plot the graph of the quadratic function

Plot the following points to graph the function

vertex (1,-9)

axis of symmetry x=1

y-intercept (0,-8)

x-intercepts (-2,0) and (4,0)

The graph in the attached figure
