Use the relationships between the angles to find the value of x (2x+16) (6x-20)
Answers
Answer:
x = 9
Step-by-step explanation:
You want to use the fact that the marked angles are congruent to find the value of x. The angles are marked (6x -20)° and (2x +16)°.
Congruent anglesThe marked angles are alternate exterior angles at a transversal crossing parallel lines, so they are congruent.
(6x -20)° = (2x +16)°
4x = 36 . . . . . . . . . divide by °, add 20-2x

a simple pendulum with a length of 1.53 m and a mass of 6.84 kg is given an initial speed of 1.06 m/s at its equilibrium position
Answers
When a simple pendulum with a length of 1.53 m and a mass of 6.84 kg is given an initial speed of 1.06 m/s at its equilibrium position, the length and mass of the pendulum will affect its subsequent motion.
The period of a simple pendulum is proportional to the square root of its length, which means that the longer the pendulum, the slower it will swing. The mass of the pendulum also affects its period, but to a lesser extent. Therefore, the pendulum will continue to swing back and forth at a constant frequency, determined by its length and the acceleration due to gravity..
In terms of the amplitude and energy of the pendulum's motion, its initial speed will determine the maximum height it reaches on each swing, which will decrease over time due to frictional losses. The mass of the pendulum will also affect its energy, as a heavier pendulum will require more energy to set in motion and will lose energy more slowly over time.
In conclusion, the length and mass of a simple pendulum will influence its period, amplitude, and energy when given an initial speed. Understanding these relationships can help predict and explain the behavior of simple pendulums in various contexts.

Which expression represents the same solution as (4) (negative 3 and startfraction 1 over 8 endfraction?
Answers
The expression that represents the same solution as (4) (-3 and 1/8) is -3.125. To understand why this is the case, let's break down the given expression: (4) (-3 and 1/8)
The first part, (4), indicates that we need to multiply. The second part, -3 and 1/8, is a mixed number. To convert the mixed number into a decimal, we first need to convert the fraction 1/8 into a decimal. To do this, we divide 1 by 8: 1 ÷ 8 = 0.125
Next, we add the whole number part, -3, to the decimal part, 0.125: -3 + 0.125 = -2.875 Therefore, the expression (4) (-3 and 1/8) is equal to -2.875. However, since you mentioned that the answer should be clear and concise, we can round -2.875 to two decimal places, which gives us -3.13. Therefore, the expression (4) (-3 and 1/8) is equivalent to -3.13.

The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost. What equation will you use to find the number of weeks x you will need to save?
Answers
Answer:
a) The equation will you use to find the number of weeks x you will need to save is:
270 = 95.50 + 20x
b) The number of weeks x = 8.725 weeks
Step-by-step explanation:
Let:
The cost to join the Ski club = y
The number of weeks you will need to save = x
From the question, we have the following information:
The cost to join the Ski Club is $270. You pay a deposit of $95.50 and plan to save an additional $20 per week to pay for the cost.
The equation will you use to find the number of weeks x you will need to save is:
y = $95.50 + $20 × x
y = $270
Hence:
270 = 95.50 + 20x
Solving for x
270 = 95.50 + 20x
270 - 95.50 = 20x
174.5 = 20x
x = 174.5/20
x = 8.725 weeks
Hence, the number of weeks needed to save is 8.725 weeks

Answers
Graph each quadratic function. State the domain and range. Also include a chart.
Answers
We can construct a chart, a table for the values of the given function as follows:
1. We need to have the function g(x) = -4x^2.
2. We can obtain the values for the function for the values:
x = -4, x = -2, x = 0, x = 2, x = 4.
3. We need to evaluate the function for each of these values.
4. Finally, we can have a table of the values of x and y.
Having this information into account, we can proceed as follows:
1. x = -4
\(f(-4)=-4(-4)^2=-4\cdot(16)=-64\Rightarrow f(-4)=-64\)2. x = -2
\(f(-2)=-4(-2)^2=-4(4)\Rightarrow f(-2)=-16\)3. x = 0
\(f(0)=-4(0)^2=-4\cdot0\Rightarrow f(0)=0\)4. x = 2
\(f(2)=-4(2)^2=-4\cdot4\Rightarrow f(2)=-16\)5. x = 4
\(f(4)=-4(4)^2=-4\cdot16\Rightarrow f(4)=-64\)Then, having these values, we can construct the values for the function using these values:
We can draw part of this function using these values. We have to remember that, in functions, we can say that y = f(x).
We can also say that the domain of the function is, in interval notation:
\((-\infty,\infty)\)And the range, as we can see from the values, is as follows (using interval notation):
\((-\infty,0\rbrack\)This is because the values for y (or f(x)) are less or equal to zero.
In summary, we can have a table to construct a graph using the values for the independent variable and plug these values in the function to obtain the values for y.
We need to remember that y = f(x). Additionally, this function has a domain from -infinity to infinity (all the values in the Real set), and a range for values from -infinity to 0 (including zero).
A graph for this function is as follows:

What is the domain and range of X² y² 9?
Answers
The domain and range of x² + y² = 9 are:
Domain: [−3, 3],{x| −3 ≤ x ≤ 3}
Range: [−3,3],{y| −3 ≤ y ≤3}
What are the domain and range?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
We have,
x² + y² = 9
Subtract x² from both sides of the equation.
y² = 9 − x²
Take the square root of both sides of the equation
y² = ±√9 − x²
Simplify ±√9 − x²
y = ±√(3+x) (3-x)
The complete solution is the result of both the positive and negative portions of the solution.
y = √(3+x) (3-x)
y = -√(3+x) (3-x)
(3+x) (3-x) ≥ 0
for x.
−3 ≤ x ≤ 3
The domain is all values of x that make the expression defined.
Interval Notation: [−3, 3]
The range is the set of all valid y values. Use the graph to find the range.
Interval Notation: [−3, 3]
Hence, the domain and range of x² + y² = 9 are:
Domain: [−3, 3],{x| −3 ≤ x ≤ 3}
Range: [−3,3],{y| −3 ≤ y ≤3}

When a figure is dilated from the origin, each ordered pair of the image, maybe found according to the rule (x,y)->(kx, ky)
Answers
Yes, that's correct. When a figure is dilated from the origin, each ordered pair of the figure is transformed according to the rule
What is dilation in maths ?
A dilation is a function f from a metric space M into itself that fulfils the identity d=rd for all locations x, y in M, where d is the distance between x and y and r is some positive real number.
Yes, that's correct!
When a figure is dilated from the origin, each ordered pair of the figure is transformed according to the rule (x, y) → (kx, ky), where k is the scale factor. The scale factor determines the size of the dilation; if k > 1, the dilation increases the size of the figure, while if 0 < k < 1, the dilation decreases the size of the figure. If k = 1, the figure remains unchanged.
It's important to note that dilations preserve the orientation of the figure and can be thought of as a non-uniform scaling of the figure.

The percent of increase can be calculated as:
\(\frac{v_f-v_i}{v_i}\times100\)Where vf is the final value and vi is the initial value. So, replacing vf by 10.75 and vi by 9.25, we get:
\(\frac{10.75-9.25}{9.25}\times100=\frac{1.5}{9.25}\times100=16.22\text{ \%}\)Therefore, the percent of the increase is 16.22%

What is the probability that the person has blue eyes?
Give your answer as a decimal correct to 2 decimal places.
Answers
The probability that one person chosen has blue eyes is 0.57.
The given parameters:
Number of females, = 60 Number of males, = 70Probability of choosing a female with blue eyes, = 0.41Probability of choosing a male with blue eyes, = 0.7The total number of female and male with blue eyes is calculated as;
Total female with blue eyes = 0.41 x 60 = 24.6
Total male with blue eyes = 0.7 x 70 = 49
Total blue eyes = 24.6 + 49 = 73.6
The probability that one person chosen has blue eyes is calculated as follows;
\(P = \frac{73.6}{60 + 70}\\\\P = \frac{73.6}{130} \\\\P = 0.566\\\\P \approx 0.57\)
