Evaluate (2-5i)(p+q)i when p=2 and q=5i
a. 29i
b. 29i-20
c. -21i
d. 29
Answer:
Answer:
The value of the (2 – 5i)(p + q)i is 29i .
Option (a) is correct .
Step-by-step explanation:
As the expression given in the question.
= (2 - 5i) (p + q)i
Simplify the above
= (2 - 5i) (pi + qi)
= 2pi + 2qi - 5pi²- 5qi²
As i² = -1
Put in the above
= 2pi + 2qi + 5p +5q
= 2i × 2 + 2i × 5i + 5 × 2 + 5 × 5i
= 4i + 10i² + 10 + 25i
As i² = -1
= 4i - 10 + 10 + 25i
= 29i
Thus the value of the (2 – 5i)(p + q)i is 29i .
Option (a) is correct .

A rectangle has length of 5.25 cm and area of 44.625 cm. What does the length of the rectangle have to be?
Answer: 8.25 cm
Step-by-step explanation:
We know that the area of rectangle is given by :-
[tex]\text{Area}=\text{Length}\times\text{Width}[/tex]
Given : The length of rectangle: l= 5.25 cm
The area of rectangle:[tex] A=44.625\ cm^2[/tex]
Substitute the values of A and l in the formula given above, we get
[tex]44.625=5.25\times\text{Width}[/tex]
Divide 5.25 both sides , we get
[tex]\text{Width}=\dfrac{44.625}{5.25}=8.5[/tex]
Hence , the other length of the rectangle have to be 8.25 cm.

Solve the equation using square roots. x^2 – 14 = –10
Answer:
[tex]x=\pm2[/tex]
Step-by-step explanation:
The given equation is
[tex]x^2-14=-10[/tex]
Add 14 to both sides of the equation.
[tex]x^2=-10+14\\\\x^2=4[/tex]
Now, take square root both sides. Whenever, we take square root both sides, we include plus minus sign
[tex]\sqrt{x^2}=\pm\sqrt{4}[/tex]
On simplifying, we get
[tex]x=\pm2[/tex]

do Dollar markdowns represent price increases to the original selling price.
No, dollar markdowns do not represent price increases to the original selling price.
In retail, a markdown refers to a reduction in the price of an item from its original selling price. When a dollar markdown occurs, it means that the price of the item has been decreased by a specific dollar amount. This reduction is typically implemented to stimulate sales, clear out excess inventory, or attract customers.
For example, if an item originally priced at $50 is marked down by $10, the new selling price would be $40. Therefore, dollar markdowns signify a decrease in the selling price relative to the original price, rather than an increase. They are a common strategy used by retailers to adjust pricing to match market demand and drive sales.

which class (sophomore, junior, or senior) had the lowest cumulative college gpa? what is the approximate value of that gpa?
Without the specific GPA data for the sophomore, junior and senior classes, it's impossible to determine which of these classes had the lowest cumulative college GPA.
Explanation:Unfortunately, from the data provided, we can't determine which class (sophomore, junior, or senior) had the lowest cumulative college GPA and the approximate value of that GPA. The information given relates more to correlation coefficients, random number generation, precalculus classes, and high school student classifications, but nothing specifically providing the desired GPA data.
Without specific GPA data for each class (sophomore, junior, senior), it's not possible to make an accurate deduction. An authoritative answer would be dependent on obtaining this specific data.

The length of a rectangular field is 30 more than twice its width. Write an expression in simplest form for the perimeter of the field in terms of its width w.
The expression for the perimeter of a rectangular field where the length is 30 more than twice its width, in terms of the width w, is 6w + 60.
The perimeter of a rectangle is given by the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. According to the problem, the length (l) of the rectangular field is 30 more than twice its width (w). So we can express the length as l = 2w + 30.
Substituting this expression into the perimeter formula, we get:
P = 2(2w + 30) + 2w
Simplifying this expression, we get:
P = 4w + 60 + 2w = 6w + 60
So, the expression for the perimeter of the field in terms of its width w is 6w + 60, which is already in its simplest form.

What are the slope and y intercept form for the graph of y+9x=-6
The slope of the graph for the equation y + 9x = -6 is -9, and the y-intercept is -6, which corresponds to the point (0, -6) on the y-axis.
The equation y + 9x = -6 can be re-written in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. To find the slope and y-intercept from the given equation, we need to isolate y on one side. Here's how we do it step-by-step:
Start with the given equation: y + 9x = -6.Subtract 9x from both sides to isolate y: y = -9x - 6.The slope (m) is the coefficient of x, which is -9, and the y-intercept (b) is the constant term, which is -6. Thus, the slope is -9, and the y-intercept is the point (0, -6) on the y-axis.

Three is less than the sum of a number s and 4
Answer:
Expression is,
[tex]3 < s + 4[/tex]
Solution is -1 < s.
Step-by-step explanation:
Given phrase,
Three is less than the sum of a number s and 4,
∵ Sum of s and 4 = s + 4,
Now, in the inequality,
We use < for 'less than'
Hence, 3 is less than s + 4
[tex]\implies 3 < s + 4[/tex]
Which is the required expression,
By solving it,
[tex]3-4<s[/tex]
[tex]\implies -1<s[/tex]
calculate the total resistance for a 650 ohm, a 350 ohm, and a 1000 ohm resistor connected in series
The total resistance for the given resistors connected in series is 2000 ohms.
Explanation:To calculate the total resistance for resistors connected in series, you simply add up the individual resistances. In this case, the resistances are 650 ohm, 350 ohm, and 1000 ohm. So the total resistance would be:
Total Resistance = 650 ohm + 350 ohm + 1000 ohm = 2000 ohm
