The area of the canvas covered by the red rose is 370 square inches, calculated by multiplying the width and height of the canvas to find the total area and then taking 50% of that area.
The task is to calculate the area of a canvas that was covered by a red rose painting, which took up 50% of the total canvas area. To find the area covered by the red rose, we first need to calculate the total area of the canvas. The total area (A) of a rectangle is calculated by multiplying its width (W) by its height (H), which gives us the formula:
A = W x H
In this case, Kendra's canvas is 20 inches wide and 37 inches high. Using the formula:
A = 20 inches x 37 inches = 740 square inches
Now, since the red rose covers 50% of the canvas, we simply take 50% of the total area to find the area covered by the red rose:
Area covered by the red rose = 50% of 740 square inches = 0.50 x 740 square inches = 370 square inches
Therefore, the area of the canvas covered by the red rose is 370 square inches.

There are 750 toothpicks in a regular sized box. If a jumbo box is made by doubling all the dimensions of the regular sized box, how many toothpicks will the jumbo box hold? (With work pls)
To answer this, let the 3 sides of the regular sized rectangular box be x, y, and z.
When we double all the sides, the new sides have lengths 2x, 2y, and 2z, respectively.
Since the regular box (with dimensions x,y, and z) have 750 toothpicks, we can write
[tex]xyz=750[/tex]
Similarly we can write for the jumbo box as,
[tex](2x)(2y)(2z)[/tex]
which is equal to [tex]8(xyz)[/tex]
So this is 8 times the original of [tex]xyz[/tex]. Hence the jumbo box will have 8 times 750 number of toothpicks.
ANSWER: [tex]8*750=6000[/tex] toothpicks
Answer:

What is the range of the function y = -x2 + 1?
Final answer:
The range of the function y = -x^2 + 1 is all real numbers less than or equal to 1, represented as ]-∞, 1].
Explanation:
The range of the function y = -x^2 + 1 refers to the set of all possible values that y can take as x varies over all real numbers. Since the function is a downward-opening parabola (due to the negative coefficient of x^2), the maximum value of y is at the vertex of the parabola. The vertex, in this case, occurs at x=0, which gives us the maximum y value of y = 1. As x moves away from zero in either direction, the value of y decreases and approaches negative infinity. Hence, the range of this function is ]-∞, 1], or all real numbers less than or equal to 1.
For an investment of $26,245, a quarterly statement reports that the account balance is $26,292. The statement also reports that for the same quarter, the rate of return on the investment was -0.02%. Given the information regarding the investment's current balance, does the reported rate of return seem reasonable? Use complete sentences to explain your answer.
Answer:
Rate of return is 0.2% positive according to given data. The given rate of return is inconsistent with the given data.
Step-by-step explanation:
The rate of return on the statement is inconsistent with the information given.
As per given data
Investment = $26,245
Account balance = $26,292
Return on the investment
Difference = $26,292 - $26,245 = $47
Investment is increase by $47
Now calculate the percentage of rate of return.
Percentage change = ($47 / $26,245) x 100 = 0.2%
Rate of return is 0.2% positive according to given data. Hence proved that, the given rate of return is inconsistent.

Which of the following is a solution of x2 + 6x = −18?
The correct option are a. [tex]\(x = -3 + 3i\)[/tex] and b. [tex]\(x = -3 - 3i\)[/tex].The solutions are complex numbers [tex]\(x = -3 + 3i\)[/tex] and [tex]\(x = -3 - 3i\)[/tex].
To find the solution of the quadratic equation [tex]\(x^2 + 6x = -18\)[/tex], we need to solve it for [tex]x[/tex].
Starting with the given equation:
[tex]\[x^2 + 6x = -18\][/tex]

[tex]\[x = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{{2a}}\][/tex]
where [tex]\(a = 1\), \(b = 6\)[/tex], and [tex]\(c = 18\).[/tex]
Substituting the values:
[tex]\[x = \frac{{-6 \pm \sqrt{{6^2 - 4 \cdot 1 \cdot 18}}}}{{2 \cdot 1}}\]\[x = \frac{{-6 \pm \sqrt{{36 - 72}}}}{2}\]\[x = \frac{{-6 \pm \sqrt{{-36}}}}{2}\]\[x = \frac{{-6 \pm 6i}}{{2}}\]\[x = -3 \pm 3i\][/tex]
So, the solutions are complex numbers [tex]\(x = -3 + 3i\)[/tex] and [tex]\(x = -3 - 3i\)[/tex].

The solutions of the trigonometric equation are approximately 0.56, 2.58, 3.71 and 5.72, all in concordance with the results found beside the analytical approach.
How to solve trigonometric equations
Trigonometric functions are periodic functions, cosine function has a standard period of 2π radians. There are two approaches to solve the expression given, an analytical one and a graphical one. Now we proceed to show each approach:
Analytical method
Now we proceed to apply algebraic handling and inverse trigonometric functions to solve the expression for t:
7 · cos 2t = 3
cos 2t = 3/7
2 · t = cos⁻¹ (3/7)
There are two solutions:
2 · t₁ ≈ 0.359π + 2π · i ∨ 2 · t₂ ≈ 1.641π + 2π · i
t₁ ≈ 0.180π + π · i ∨ t₂ ≈ 0.821π + π · i
t₁₁ ≈ 0.180π ∨ t₁₂ ≈ 1.180π ∨ t₂₁ ≈ 0.821π ∨ t₂₂ ≈ 1.821π
The solutions of the trigonometric equations in [0, 2π] are approximately 0.18π, 0.82π, 1.18π and 1.82π.
Graphical approach
First, we add the definition of the following two functions (f(x) = 7 · cos 2t and g(x) = 3) and plot in the calculator through a graphing tool. The solutions of this trigonometric function are the points of intersection of the two functions.
According to the image attached below, the solutions of the trigonometric equation are approximately 0.56, 2.58, 3.71 and 5.72, all in concordance with the results found beside the analytical approach.

Determine the values of x on which the function f(x)=2x^2-x-15/4x^2-12x is discontinuous and verify the type of discontinuity at each point.
A.There is a vertical asymptote at 0 and a hole at 3.
B.There are vertical asymptotes at -5/2 & 0 and a hole at 3.
C.There is a vertical asymptote at 3 and a hole at 0.
D.There are vertical asymptotes at 0 & 3.
There is a vertical asymptote at x = 0 (because the denominator becomes 0). We need to further analyze the behavior at x = 3 to see if it's a hole (cancellation) or the function is continuous there (Option A or B might be the answer).
Step 1: Identify Potential Discontinuities
A rational function (like f(x)) is discontinuous when its denominator is zero. So, we need to find the values of x that make the denominator 0:
Denominator = 4x^2 - 12x = 0
Factor the denominator: 4x(x - 3) = 0
This gives us two possible values for x: x = 0 and x = 3.
Step 2: Verify Discontinuity Type at Each Point
Check if the function is defined (has a value) at these points.
x = 0: If we plug x = 0 in the original function, we get 0/0, which is indeterminate. This suggests a potential vertical asymptote at x = 0.
x = 3: If we plug x = 3 in the original function, the expression doesn't become 0/0. The function might have a hole or be continuous at x = 3.
Step 3: Analyze for Holes (Optional):
To further investigate x = 3, we can try to simplify the function by factoring the numerator (possible because the denominator is already factored). If the simplification gets rid of the term that causes the 0/0 at x = 3, it creates a hole.
