Answer:
[tex]x=4.865[/tex]
Step-by-step explanation:
We know the area of a rectangle to be [tex]base*height[/tex]. In this instance, [tex]base=(2x+10)in[/tex], [tex]height=(3x) in[/tex], and [tex]area=288in^2[/tex]
The next step is to plug these known values into the [tex]area=base*height[/tex] equation. It'll look like this:
[tex]288=(2x+10)*(3x)=6x^2+30x[/tex]
This simplifies to:
[tex]48=x^2+5x[/tex]
Next, we want to rewrite the equation so we can apply the quadratic formula to it. We are going to do this by subtracting 48 from each side. The new equation looks like this:
[tex]x^2+5x-48=0[/tex]
Next, we plug this into the quadratic formula:
[tex]x=\frac{-(5)+\sqrt{5^2-4(1)(-48)} }{2(1)}=4.865[/tex]
[tex]x=\frac{-(5)-\sqrt{5^2-4(1)(-48)} }{2(1)}=-9.865[/tex]
The second value of x is negative, and since a side length cannot be negative this leaves us with just the first answer of [tex]x=4.865[/tex].
Answer:
[tex]\Large \boxed{\boxed{\textsf{$\therefore x=4.87 $ in}}}[/tex]
Step-by-step explanation:
The area of a rectangle is equal to the base × height:
[tex]\large \textsf{$\rm A $ $= (2x+10)\times(3x)$}\\ \\\large \textsf{$\rm \phantom{A}=$ $6x^2+30x$, and since A = 288,}\\ \\\large \textsf{$\therefore 288 = 6x^2+30x$}[/tex]
Rearranging this equation, we get:
[tex]\large \textsf{$6x^2+30x-288=0$}\\\\\large \textsf{$6(x^2+5x-48)=0$}\\\\\large \textsf{$\therefore x^2+5x-48=0$}[/tex]
Here we are left with a quadratic equation, which we can solve using the quadratic formula:
[tex]\Large \boxed{\textsf{$x = \frac{-b\pm \sqrt{b^2-4ac}}{2a}$}} \textsf{ where $ax+bx+c=0$}[/tex]
Plugging values into the formula, we get:
[tex]\Large \textsf{$x = \frac{-(5)\pm \sqrt{(5)^2-4(1)(-48)}}{2(1)}$} \\\\\Large \textsf{$x=4.87, -9.87$,} \large \textsf{ but length cannot be negative.}\\\\\Large \boxed{\boxed{\textsf{$\therefore x=4.87 $ in}}}[/tex]

14. Evaluate the indefinite integral.
The indefinite integral of ∫ (4x⁴ - 5)⁵ . 32x³ dx is (4x⁴ - 5)⁶/3 + C.
What is the indefinite integral?The solution of the indefinite integral is calculated by using substitution method.
Let u = 4x⁴ - 5
du/dx = 16x³
dx = du/(16x³)
Substituting into the integral;
∫ (4x⁴ - 5)⁵ . 32x³ dx = ∫ u⁵ . 32x³ du/(16x³)
∫ u⁵ . 32x³ du/(16x³) = ∫ 2u⁵ du
∫ 2u⁵ du = 2∫u⁵ du
2∫u⁵ du = 2 (u⁶/6 + C)
2 (u⁶/6 + C) = u⁶/3 + C

Abe purchased a candle at the candle store. The candle is nine inches long and the packaging states the candle burns down at the rate of 1/2 an inch per hour. Write a function to determine the length of the candle, y, after burning for x number of hours.
After burning for x hours, the candle's length, y, is calculated using the formula: y = 9 - (1/2)x.
Let y represent the length of the candle that is still burning after burning for x hours.
Since the candle burns at a rate of 1/2 inch per hour, we can use the following equation to explain the connection between the candle's length and the number of hours burned:
y = 9 - (1/2)x
Here, 9 represents the original length of the candle, and (1/2)x represents the length of the candle burned after x hours.
By subtracting the length burned from the original length, we obtain the length remaining after x hours.
Therefore, the function that determines the length of the candle, y, after burning for x number of hours is:
y = 9 - (1/2)x

The measure of arc CFE is 246⁰.
The measure of arc FED is 190⁰.
The value of the angle CFE is 57⁰.
The value of the angle DEF is 85⁰.
What are the values of the angles?The value of the angles is calculated by applying intersecting chord theorem.
This theorem states that the angle at tangent is half of the arc angle of the two intersecting chords.
angle CFE = 180 - 123 (opposite angles of a cyclic quadrilateral)
angle CFE = 57
arc CDF = 2 x 57
arc CDF = 114
arc CFE = 360 - 114 = 246⁰
angle DEF = 180 - 95
angle DEF = 85

The drawer contains 18 spoons and 12 forks. you randomly choose two utensils. What is the probability that both utensils are spoons?
Answer:8.52%
Step-by-step explanation:
There are 14 utensils in the drawer, and then there will be one less in the bowl after each successive utensil is removed. There are then 3 possibilities for the same kind being removed on all pulls:
P(3 spoons) = (6/14)*(5/13)*(4/12)
P(3 forks) = (5/14)*(4/13)*(3/12)
P(3 knives) = (3/14)*(2/13)*(1/12)

How to find the lateral area and surface area of a triangular prism?The lateral area of a right triangular prism is given by:
LA = perimeter of base triangle * height
LA = (a + b + c) * h (check attached image for labeling)

The required graph has been attached below that represents the function f(x) = 5 cos (2x).
The graph of the function f(x) = 5 cos(2x) is a periodic function that oscillates between its maximum and minimum values as x changes.
Specifically, the function is a cosine function with amplitude 5 and period π, since the coefficient of x is 2 in the argument of the cosine function.
The graph of the function f(x) = 5 cos(2x) has a maximum value of 5 when cos(2x) = 1 (i.e., at 2x = 0 + 2πk, where k is an integer), and a minimum value of -5 when cos(2x) = -1 (i.e., at 2x = π + 2πk, where k is an integer).

Interferes that are closest to the number in the middle 69 squared
The numbers closest to the middle of the squares of consecutive integers around 69² are 4624 and 4761, which are at the squares of 68 and 69, respectively.
To find the number closest to the middle of the squares of consecutive integers around 69², we can use the fact that the squares of consecutive integers increase by an odd number. Specifically, the difference between the squares of consecutive integers n and n+1 is
(n+1)² - n² = 2n + 1
Therefore, the squares of consecutive integers around 69² are
67² = 4489
68² = 4624
69² = 4761
70² = 4900
71² = 5041
The middle of these squares is between 69² and 70², which is
(69² + 70²)/2 = 9674.5
So, we want to find the squares of the integers closest to 9674.5. Since 69 is closer to 9674.5 than 70, the two squares that are closest are

y = 20/7
We have,
The two equations are:
x + y = 7 ______(1)
x² - y² = 15 _______(2)
We can use the method of substitution.
From the first equation.
y = 7 - x
We can substitute this expression for y into the second equation.
x² - (7 - x)² = 15
Expanding the square in the second term gives:
x² - (49 - 14x + x²) = 15
Simplifying this equation.
-14x + 34 = 0
Solving for x gives:
x = 17/7
Substituting this value of x into the first equation.
y = 7 - x = 20/7
Therefore,
The solution to the set of equations are:
x = 17/7
y = 20/7

Simplify the following expression 12a3b6c5/3a2b4c5
4ab² is the simplified value of the given expression.
To simplify the expression, we can divide the coefficients and variables separately:
[tex]12a^3b^6c^5 / 3a^2b^4c^5\\\\= (12/3) * (a^3/a^2) * (b^6/b^4) * (c^5/c^5)\\\\= 4 * a^{3-2}* b^{6-4} * c^{5-5}\\\\= 4a * b^2 * 1\\\\= 4ab^2\\[/tex]
Therefore, the simplified expression is 4ab².
