graph the function f(x) = 3(4)^x
Answer:
That depends on how accurate you are with pen and paper.
You can tell it's a growing exponential, so the form is the traditional one. If you are particularly inclined in crunching numbers and working on a grid I would pick 0, 1 and -1, 1/2 and -1/2, a few positive integers, and that's it.
If not, i would be satisfied saying that when x = 0 (ie, the y intercept) y= 3, and that's all. Then, my drawing is made with paint, don't expect a masterpiece.

the ranch house serves a 24 oz sirloin steak that has a total of 1,800 calories. how many calories per ounce does the steak have
The amount of calories per ounce does the steak have is 75 calories per ounce.
Using this formula
Calories per ounce=Total calories/Number of oz sirloin steak
Where:
Total calories=1,800 calories
Number of oz sirloin steak=24 oz
Let plug in the formula
Calories per ounce=1800/24 oz
Calories per ounce=75 calories per ounce
Inconclusion the amount of calories per ounce does the steak have is 75 calories per ounce.

The quotient of a number and -4 is -9
Answer:36
Step-by-step explanation:36÷ -4 = -9
The answer would be 36 which is 36÷ -4 = -9 after applying the arithmetic operation.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The quotient of a number and -4 is -9
Mathematically we can write:
x ÷ -4 = -9
x/(-4) = -9
x = 36
OR
36 ÷ -4 = -9
Thus, the answer would be 36 which is 36÷ -4 = -9 after applying the arithmetic operation.

Eliminate the parameter, t, in the parametric equations, x = 3cos(t) and y = -6sin(t).
A) 2 x2 + y2 = 36
B) x2 + y2 = 2
C) 4 x2 + y2 = 36
D) x2 + y2 = 36
Recall that
cos²(t) + sin²(t) = 1
Then solving for cos(t) and sin(t), we have
x = 3 cos(t) ===> cos(t) = x/3
y = -6 sin(t) ===> sin(t) = -y/6
so that the above identity gives us
(x/3)² + (-y/6)² = 1
x²/9 + y²/36 = 1
36 (x²/9 + y²/36) = 36
(C) 4x² + y² = 36
The parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
We have two parametric equations:
x = 3cos(t) and
y = -6sin(t).
As we know, the trigonometric identity:
sin²θ + cos²θ = 1
For checking the option (A):
2x² + y² = 36
= 2(3cos(t))² + (-6sin(t))²
= 18cos²t + 36sin²t ≠ 36
Similarly, for checking the option:
4x² + y² = 36
= 4(3cost)² + (-6sint)²
= 36cos²t + 36sin²t
= 36(cos²t + sin²t)
= 36(1) = 36
Thus, the parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).

Describe the domain and range. Graph the function. What do I do with the -3? The graph shows that y and x are at 0 so...?
Answers:
Domain: all real numbers
Range: [tex]y \le 6[/tex]
Graph is below.
====================================================
Explanation:
This is a piecewise function that is composed of two parts:
The first piece being y = x+6 but only when [tex]x \le 0[/tex]The second piece occurs when x > 0 and that piece is y = -3xThis piecewise function has split identities or multiple aliases so to speak. It all depends on what the x input is.
The graph is shown below.
The domain is the set of all real numbers since any x value will lead to some y output. Even x = 0 itself is allowed. Note the arrows indicate the graph stretches on forever to the left and to the right.
The range on the other hand isn't all real numbers. Instead, it's [tex]y \le 6[/tex] indicating that y = 6 is the largest y can get. Simply locate the highest point on the graph (similar to the concept of the vertex) and you'll spot the highest y value.
Side notes:
The domain in interval notation is [tex](-\infty, \infty)[/tex] which encompasses the entire real number line.The range in interval notation is [tex](-\infty, 6][/tex] where the square bracket includes the endpoint 6.Match each system of equations to its point of intersection.
y = 2x + 1
y = x + 3
y = x + 3
y = -3x - 2
y = -x - 7
y = x + 3
y = -x - 7
y = 2x + 1
y = 2x + 1

A rectangular prism is made up of 320 unit cubes. The prism is 8 unit cubes wide.
Which could be the other dimensions of the rectangular prism? Choose all the possible dimensions.
A. 4 unit cubes long
10 unit cubes high
B. 5 unit cubes long
8 unit cubes high
C. 8 unit cubes long
5 unit cubes high
D. 8 unit cubes long
8 unit cubes high
E. 10 unit cubes long
4 unit cubes high
F. 20 unit cubes long
2 unit cubes high
G. 20 unit cubes long
20 unit cubes high
H. 25 unit cubes long
15 unit cubes high
Answer:
A, B, C, E, F.
Step-by-step explanation:
320 / 8 = 40
So the length times the height of the prism will be 40.
So the possible dimensions are
A ( 4 * 10).
B.
C.
E.
F
The option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.
What is a rectangular prism?It is defined as the six-faced shape, a type of hexahedron in geometry.
It is a three-dimensional shape. It is also called a cuboid.
We have volume of rectangular prism = 320 cubic unit
Width of the rectangular prism = 8 unit
320 = l×w×h
320 = 8l×h
l×h = 40
So the multiplication of the length and height should be 40
A. 4 unit cubes long and 10 unit cubes high:
l×h = 4×10 = 40
B. 5 unit cubes long and 8 unit cubes high:
l×h = 5×8 = 40
C. 8 unit cubes long and 5 unit cubes high:
l×h = 8×5 = 40
D. 8 unit cubes long and 8 unit cubes high:
l×h = 8×8 = 64
E. 10 unit cubes long and 4 unit cubes high:
l×h = 10×4 = 40
F. 20 unit cubes long and 2 unit cubes high:
l×h = 20×2 = 40
G. 20 unit cubes long and 20 unit cubes high:
l×h = 20×20 = 400
H. 25 unit cubes long and 15 unit cubes high:
l×h = 25×15 = 375
Thus, the option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.
