This figure has two intersecting lines and a ray.
What is the value of x?
Enter your answer in the box.
x =
The figure contains a pair intersecting lines. One of the four angles formed by the intersecting lines is labeled 146 degrees. The angle opposite and not adjacent to this angle is broken into two smaller angles by a ray that extends from the point where the two lines intersect. One of these smaller angles is labeled 58 degrees, and the other smaller angle is labeled x degrees.
The 146°, and the x and 58° which are vertical angles formed by the two intersecting lines where the x and 58° are formed by the ray gives the measure of x as 88°
What are vertical angles?Vertical angles or vertically opposite angles are the angles formed by two intersecting lines and which are on either side to each other
The description parameters are;
The objects in the figure includes; Two intersecting lines and a ray
The measure of one of the angles formed by the intersecting lines = 146°
The vertically opposite angle to the 146° angle is broken into = x and 58°
Required; The value of x
Solution; The vertical angles theorem states that vertically opposite angles that are formed when two lines intersect, are congruent.
In geometry, two figures are congruent when they exactly coincide when they are superimposed, which means that the two figures have the same measurement.
Given that 146° is congruent to x + 58°, we have;
146° = x + 58° Definition of congruency and angle addition postulate
x = 146° - 58° = 88°

To pay for a home improvement project that totals $16,000, Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years or paying with a credit card that compounds monthly at an annual rate of 15% for 7 years. Which plan would give Genesis the lowest monthly payment?
well, let's first check with the Bank
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$16000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ t=years\dotfill &3 \end{cases} \\\\\\ A=16000[1+(0.08)(3)] \implies A = 19840~\hfill \underset{monthly~payment}{\stackrel{19840~\div \stackrel{months}{36}}{\approx \text{\LARGE 551.11}}}[/tex]
now let's check with the Credit Card
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$16000\\ r=rate\to 15\%\to \frac{15}{100}\dotfill &0.15\\ n= \begin{array}{llll} \textit{times it compounds per year} \end{array}\dotfill &12\\ t=years\dotfill &7 \end{cases}[/tex]
[tex]A=16000\left(1+\frac{0.15}{12}\right)^{12\cdot 7} \implies A \approx 45425.81~\hfill \underset{monthly~payment}{\stackrel{45425.81~\div \stackrel{months}{84}}{\approx\text{\LARGE 540.78}}}[/tex]
well, seems the Credit Card is the better deal monthly wise, though in the long run is a lot of dough.
A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.
What is simple interest?Mathematically, the simple interest earned can be calculated by using this formula:
A = P(1 + rt)
Where: A represents the future value.
P represents the principal or original value.
r represents the interest rate.
t represents the time.
Now Substituting the given parameters into the formula, we have,
A = 9000[1 + (0.09 × 3)]
A = 9000[1 + 0.27]
A = 9000 × 1.27
Future value, A = $11,430.
Next, we will calculate the monthly payment over a period of 36 months as follows:
Monthly payment = Future value/Time
Monthly payment = 11,430/36
Monthly payment = $317.50.
Similarly, we will calculate the compound interest earned on the credit card :
A = 9000[1 + (0.18/12)]⁽¹² ˣ ⁷⁾
A = 9000[1 + 0.015]⁸⁴
A = 9000 × 1.015⁸⁴
A = 9000 × 3.49258954
Future value, A = $31,433.31.
Next, we will calculate the monthly payment over a period of 84 months as follows;
Monthly payment = Future value/Time
Monthly payment = 31,433.31/84
Monthly payment = $372.21.
In this context, A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.

an elliptical arch is constructed which is 6 feet wide at the base and 9 feet tall in the middle. find the height of the arch exactly 1 foot in from the base of the arch.
The height of the arch is about 6.71 feet when measured from its base at a distance of one foot.
This is further explained below.
What is an ellipse?Generally, An ellipse is a collection of points whose distances from a fixed point (focus) or fixed line (directrix) is constant and less than 1.
Depending on whether the transverse axis is horizontal or vertical, we may construct an equation for the ellipse. The main axis is located along the transverse axis. The ellipse may be represented using the following equations:
[tex]\begin{aligned}&\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1 \\&\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1\end{aligned}[/tex]
An elliptical arch is described as having a center height of 9 feet and a width of 6 feet. The precise height of the arch from the base has to be determined.
[tex]\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1[/tex]
The center (h, k) is where the graph is since we centered it at the origin (0,0). We only need to enter the numbers into the equation at this point.
[tex]\begin{aligned}\frac{(y-0)^2}{9^2}+\frac{(x-0)^2}{3^2} &=1 \\\frac{y^2}{81}+\frac{x^2}{9} &=1\end{aligned}[/tex]
Since we divided the arch in half, 0 [tex]\leq[/tex] 9 in this instance. All that is left to do is calculate the arch's height in feet from the base.
The height of 1 foot from each end of the arch must thus be determined. The locations of the arch's ends are x=-3 and x=3. Here, we have a choice between the two. We may choose x=3-1=2 for this. Therefore, all that is left to do is enter x=2 in our usual form and work out the value of y that results.
[tex]\frac{y^2}{81}+\frac{(2)^2}{9}=1[/tex]
y^2+36=81
y^2+36-36=81-36
y=3√5
Therefore, the height of the arch at 1ft from the base is 3 √5ft or approximately 6.71ft

A production process is checked periodically by a quality control inspector. The inspector selects simple random samples of finished products and computes the sample mean product weight. If test results over a long period of time show that of the values are over pounds and are under pounds, what are the mean and the standard deviation for the population of products produced with this process?.
The mean and the standard deviation for the population of products produced with this process are 2.0 and 0.3329
The population mean is given by
ц = [tex]\frac{L+U}{2}[/tex]
where L and U are the two given boundaries
Here, L = 1.9 and U = 2.1
⇒ ц = [tex]\frac{1.9+2.1}{2}[/tex]
⇒ ц = 2.0
Now, the z value when p =5%, from z table of probability will be
z = -1.645
Standard Deviation denoted by σ is a measure of how dispersed the data is in relation to the mean.
The Standard Deviation can be calculated by the z-score which is given as:
z = (x-ц) / (σ / [tex]\sqrt{n}[/tex])
where z is the Standard score, x is observed value, ц is mean of the sample, σ is standard deviation and n is sample size
-1.645 = (1.9 - 2.0) / (σ / [tex]\sqrt{30}[/tex])
-1.645 × (σ / [tex]\sqrt{30}[/tex]) = -0.1
1.645 × (σ / 5.477) = 0.1
σ = 0.3329

The ordered pair (a,b) satisfies the inequality y
The ordered pair that satisfies the inequality is (aₓ ,bₓ) .
In mathematics, an inequality is a link that compares two numbers or other mathematical expressions unfairly.
Size comparisons between two numbers on the number line are most usually made.Various types of inequalities can be represented using various notations.By definition, any monotonically growing function can be applied to both sides of an inequality without destroying their relationship (provided that both expressions are in the domain of that function). An inequality relation would be reversed if a monotonically dropping function were applied to both sides of the inequality. Examples of how to employ a monotonically declining function are the rules for the additive and multiplicative inverses for positive values.The notation a b c denotes "a b and b c," from which it also follows that a c, in accordance with the transitivity aspect discussed above. The aforementioned laws state that all three components can be changed by either adding or subtracting the same number, or by multiplying or dividing all three terms by a nonzero number, and reversing any inequalities if the number is negative. As a result, a + e + b + c is the same as a + b + e + c.Therefore we can conclude that (aₓ, bₓ) satisfies the inequality.
