Answer:
Value of x = -7
Step-by-step explanation:
Given:
First angle = 83°
Second angle = 24°
Third angle = (38 - 5x)°
Find:
Value of x
Computation:
We know that sum of all interior angle in triangle is 180°
So,
83 + 24 + 38 - 5x = 180
145 - 5x = 180
-5x = 35
x = -7
Value of x = -7

$34. 50 WITH A NET CHANGE OF -$0. 50. WHAT WAS THE
STOCK'S YIELD AT YESTERDAY'S CLOSING PRICE?
O
The yield of stock at yesterday's closing price is 3.43%.
What is Annual Dividend?Annual dividend is the profit of the stock which is divided among the shareholders, both common and preferred shareholders annually.
Given,
Annual dividend = $1.20
Today's closing price = $34.50
Net change = -$0.50
Let x be yesterday's closing price.
Net change = Today's closing price - yesterday's closing price
⇒ -0.50 = 34.50 - x
⇒ x = 34.50 + 0.50
⇒ x = 35
Yield = [tex]\frac{Annual dividend}{Price}[/tex] × 100
= [tex]\frac{1.2}{35}[/tex] × 100
= 3.4286 % ≈ 3.43 %
Hence the stock's yield at yesterday's closing price of preferred stock is 3.43 %.

What is the minimum value of the function f x )= 16x 2 )- 16x 28?
The minimum value of the given function f(x) = 16x² −16x+28 is 24.
What are the Maxima and Minima of a Function?The curve of a function has peaks and troughs called maxima and minima. A function may have any number of maxima and minima. Calculus allows us to determine any function's maximum and lowest values without ever consulting the function's graph.
To find the minimum value of the function f(x) = 16x² −16x+28 using the derivative method, you can start by taking the derivative of the function. The derivative of a quadratic function is given by:
f'(x) = 2ax + b
In this case, the derivative of the function f(x) is:
f'(x) = 2×16x - 16
To find the minimum value, we need to find the x value that makes the derivative equal to zero. Setting the derivative equal to zero and solving for x gives us:
216x - 16 = 0
32x = 16
x = 0.5
Now that we have the value of x that minimizes the function, we can plug this value back into the original function to find the minimum value:
f(0.5) = 16×(0.5)² - 16(0.5) + 28 = 4 - 8 + 28 = 24
Therefore, the minimum value of the function is 24.

In mixed number form, the change in the distance when using the new road instead of the dirt roads is 2 1/12 miles lesser.
To determine the change in the distance when using the new road instead of the dirt roads, we need to find the difference between the distance of the new road and the distance of the dirt roads.
The distance of the dirt roads is the sum of the two measurements given, which is 2 3/8 + 3 5/6 = 5 15/24 miles.
The change in the distance when using the new road instead of the dirt roads is the difference between the distance of the new road and the distance of the dirt roads, which is 4 1/3 - 5 15/24 = -2 2/24 miles.

How do one find the slope of a graph?The slope is computed mathematically as "rise over run" (change in y divided by change in x).
In accordance with the slope equation, the slope of such a line may be determined by dividing the rise of the line between two positions by the run of the same line between the same two sites.
Now, given that,

The approximate volume of the greenhouse will be 1,527 ft³.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Ellen's greenhouse is in the shape of a hemisphere.
And, The diameter of the floor is 18 feet.
Now,
Since, Ellen's greenhouse is in the shape of a hemisphere.
We know that;
⇒ The volume of Hemisphere = (2/3) πr³
Here, The diameter of the floor is 18 feet.
Hence, The radius of the floor = 18/2
= 9 feet
So, We get;
⇒ The volume of Hemisphere = (2/3) πr³
⇒ The volume of Hemisphere = (2/3) × 3.14 × 9³
= 1,527 ft³

Table a and table c b. Table a and table b c. Table b and table c d. Table c and table d.
Table a and table c defines a relationship between an input x and an output y of function.
A function is a set of ordered pairs (x, y) in which each value of x corresponds to exactly one value of y. In other words, for a given value of x, there should be only one corresponding value of y.
Looking at the tables, we can see that Table a and Table d both satisfy this condition. In both tables, for each value of x, there is only one corresponding value of y. Therefore, Tables a and d represent functions.
Table b and Table c do not satisfy this condition, because there are multiple values of y for some of the values of x.
For example, in Table b, the value of x is 24 for both (24, 53) and (24, 29). Similarly, in Table c, the value of x is 24 for both (24, 53) and (24, 29). Therefore, Tables b and c do not represent functions.

A function is a collection of ordered pairs (x, y) where each x-value is matched up with exactly one y-value. In other words, there should only be one value of y that corresponds to a certain value of x.
We can see from the tables that Tables a and Table d both meet this requirement. In both tables, there is only one value of y that corresponds to each value of x. Tables a and d so depict functions.
Because there are many possibilities of y for some of the values of x, Tables b and c do not meet this requirement.
For instance, the value of x in Table b is 24 for both (24, 53) and (24, 29). The value of x is 24 in Table c for both (24, 53) and (24, 29). Tables b and c do not, therefore, represent functions.
Tables a and c therefore show the function of input x and output y.

The required real proportion's 95% confidence interval is (0.301; 0.359).
What is a confidence interval?In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time.
Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts.
So, the sample size is 1000.
Phat = 0.33
(1 - phat) = 1 - 0.33 = 0.67
Zcritical = 1.96 at 95%
The confidence range is as follows:
Phat ± margin of error
Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]
Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]
Margin of Error = 1.96 * 0.0148694
Margin of Error = 0.0291440
Lower boundary = (0.33 - 0.0291440) = 0.300856
Upper boundary = (0.33 + 0.0291440) = 0.359144

This method helps us to learn and make out the concept of area.
The unit of area is forever measured in square units like square centimeters, square meters, square inches, and so on.
Volume: The space enclosed within the object or the space covered by any three-dimensional solid object is known as volume.

What is the vertical asymptote of y 1x − 5?
The vertical asymptote of y = 1x - 5 is x = 5, since the denominator becomes zero when x = 5 and the function is undefined at this point.
The vertical asymptote of y = 1x - 5 is x = 5. This is because when x = 5, the denominator of the function (1x - 5) becomes zero, and the function is undefined at this point. As a result, the vertical asymptote is x = 5. This can be seen by taking the limit of the function as x approaches 5 from either side. As x approaches 5 from the left, the limit of the function is negative infinity, and as x approaches 5 from the right, the limit of the function is positive infinity. Thus, the vertical asymptote of y = 1x - 5 is x = 5, since the denominator becomes zero when x = 5 and the function is undefined at this point.
