1. The function f that determines the height of the beanstalk is \(h(t) = 7 * (1.15)^t\)

2. f(1)/f(0) = 1.15.

3. f(2)/f(1) = 1.149.

Let h be the height of the beanstalk in inches after t days. Then we can write: \(h(t) = 7 * (1.15)^t\) where 1.15 is the factor by which the height increases each day.

i. To compute f(1)/f(0), we need to substitute t = 1 and t = 0 into the function f and divide:

f(1)/f(0) = [7 * (1.15)^1] / [7 * (1.15)^0]

f(1)/f(0) = 1.15/1

f(1)/f(0) = 1.15

ii. To compute f(2)/f(1), we need to substitute t = 2 and t = 1 into the function f and divide:

f(2)/f(1) = [7 * (1.15)^2] / [7 * (1.15)^1]

f(2)/f(1)= (1.3225) / (1.15)

f(2)/f(1) = 1.149

Roland's percent error is approximately 3.889%.

This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.

The positive sign indicates that Roland's measured value is slightly lower than the actual value.

To calculate Roland's percent error, we can use the formula:

Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100

Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:

Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100

Simplifying the expression within the absolute value:

Percent Error = (|-0.007| / 0.180) \(\times\) 100

Since the absolute value of -0.007 is 0.007, we have:

Percent Error = (0.007 / 0.180) \(\times\) 100

Calculating the division:

Percent Error = 0.03889 \(\times\) 100

Percent Error = 3.889%.

Answer:

for a rectangle to be rhombus its sides must be equal. when its satisfied we have square. so a rectangle can be a rhombus only if it has extra properties which would make it a square.

A rectangle is sometimes a rhombus. The correct option is B. Sometimes.

A rectangle is a quadrilateral with four right angles, meaning its interior angles measure 90 degrees each. In contrast, a rhombus is a quadrilateral with four sides of equal length, but its angles are not necessarily right angles.

The rectangle is a special type of parallelogram where all angles are right angles. Its properties include having two pairs of parallel sides and diagonals that are equal in length and bisect each other. Rectangles are commonly encountered in everyday life, from the shape of windows and doors to the screens of electronic devices.

Since a rectangle can have equal side lengths, it can also be a rhombus, but only when all four angles measure 90 degrees. Therefore, while a rectangle can be a rhombus under specific conditions, it is not always the case, leading to the answer of "Sometimes."

Answer:

the two numbers that add up to 3 but multiply to 18 are 6 and -3.

Step-by-step explanation:

We can start by using algebra to solve for the two numbers. Let x and y be the two numbers we are looking for. Then we can write two equations:

x + y = 3 (since the numbers add up to 3)

xy = 18 (since the numbers multiply to 18)

We can solve for one of the variables in terms of the other using the first equation. For example, we can solve for y:

y = 3 - x

Then we can substitute this expression for y into the second equation:

x(3 - x) = 18

Expanding the left side and simplifying, we get:

3x - x^2 = 18

Rearranging and factoring, we get:

x^2 - 3x + 18 = 0

(x - 3)(x - 6) = 0

Therefore, either x = 3 or x = 6. If x = 3, then y = 3 - x = 0, which doesn't work since we want two numbers that multiply to 18. So the two numbers are x = 6 and y = 3 - x = -3.

So the two numbers that add up to 3 but multiply to 18 are 6 and -3.

A function that has a greater maximum include the following: A. Function 1 has a larger maximum at (4, 1).

In order to determine the maximum value of function 2, we would have to take the first derivative with respect to x and then, substitute this x-value into the original function while equating it to zero (0), and then evaluate as follows;

f(x) = −x² + 2x - 15

f(x) = −2x + 2

0 = −2x + 2

2x = 2

x = 2/2

x = 1

For the maximum value of function 2, we have:

f(1) = −(1)² + 2(1) - 15

f(1) = -14

The area of the shaded portion in the equilateral triangle with sides 6 is 9√3 - 36π.

To find the area of the shaded portion in the equilateral triangle, we need to determine the area of the three arcs and subtract it from the area of the equilateral triangle.

First, let's find the area of one arc. Each arc has a radius equal to the length of the side of the equilateral triangle, which is 6. The formula for the area of a sector is A = (θ/360)πr², where θ is the central angle in degrees.

In an equilateral triangle, each interior angle measures 60 degrees, so the central angle of the arc is 120 degrees (360 degrees divided by 3). Plugging these values into the formula, we get A_arc = (120/360)π(6)² = (1/3)π(6)² = 12π.

Since there are three identical arcs, the total area of the arcs is 3 times the area of one arc, which is 3(12π) = 36π.

Now, let's find the area of the equilateral triangle. The formula for the area of an equilateral triangle is A_triangle = (√3/4)s², where s is the length of a side.

Plugging in the value of the side length, we have A_triangle = (√3/4)(6)² = (√3/4)(36) = 9√3.

Finally, we subtract the area of the arcs from the area of the equilateral triangle to find the shaded portion's area: A_shaded = A_triangle - A_arc = 9√3 - 36π.

The equation of a parabola with its vertex at the origin includes a negative coefficient 'a', the parabola opens downward. option B.

The equation y = ax² represents a parabola with its vertex at the origin. In this case, if the coefficient 'a' is negative, it determines the direction in which the parabola opens.

When 'a' is negative, the parabola opens downward. This means that the vertex, which is at the origin (0, 0), represents the highest point on the graph, and the parabola curves downward on both sides.

To understand this concept, let's consider the basic equation y = x², which represents a standard upward-opening parabola. As 'a' increases, the parabola becomes narrower. Conversely, when 'a' becomes negative, it flips the parabola upside down, resulting in a downward-opening parabola.

For example, if we have the equation y = -x², the negative coefficient causes the parabola to open downward. The vertex remains at the origin, but the shape of the parabola is now inverted.

In summary, when the equation of a parabola with its vertex at the origin includes a negative coefficient 'a', the parabola opens downward. This can be visually represented as a U-shape curving downward from the origin. So Optyion B is correct.

Step-by-step explanation:

functions can only have domains that are different numbers, (first number) the rest repeat the domain and that makes it not a function

Answer:

C

Step-by-step explanation:

A set of pairs is a function if and only if there is only one y-value for each x-coordinate. In other words, the x-coordinate cannot repeat. If it does, then it must equal the same thing.

Let's go through each of the choices.

For A, -5 repeats twice. It simultaneously equals both 4 and -2. This cannot be true if this is a function, so A is not correct.

For B, 2 repeats twice. It equals both 6 and -6. So, this is also not a function.

For C, no digits are repeating. Thus, this is a function.

To make sure, in D ,-3 is repeating. It is both -4 and 8, so this is not a function.

So, our answer is C.
