Answer:
b=-√-36
b=+√36
Step-by-step explanation:
b^2+36=0
Substrate 36 from both sides
b^2=-36
Square root both sides
b=+or -√-36
So b=+√-36
Or b=-√-36
The quadratic equation [tex]b^2[/tex] + 36 = 0 does not factor into real numbers due to the presence of a negative constant, but it factors over the complex numbers as (b + 6i)(b - 6i).
The equation [tex]b^2[/tex] + 36 = 0 is a quadratic equation of the form a[tex]x^2[/tex] + bx + c = 0, where a is 1, b is 0, and c is 36. To factor this equation, we first need to move 36 to the other side to set the equation to zero, resulting in [tex]b^2[/tex] = -36. This equation does not factor into real numbers because the square of a real number cannot be negative.
However, we can factor it over the complex numbers as (b + 6i)(b - 6i) = 0 where i is the imaginary unit.
What is 119 times 31%
Answer:
61.69?
Step-by-step explanation:
Are you asking what 31% of 119 is? If so, then the answer would be 61.69.
Because (119)0.31=61.69
(To make a percent, you take a decimal out of 1, and multiply. 0.31 would be 31, because we would multiply it by 100, becuase you can only get to 100%. Then you woukd do the opposite, reverse it by dividing by 100. Which then, you would get 0.31)

Which dimensions can create only one unique triangle?
Answer:
case A. Three angles measuring 25,65,and 90
sum of a internal angles=25+65+90-----> 180° is ok
That dimensions can create infinity similar triangles
case B. Three angles measuring 50,50,and 50
sum of a internal angles=50+50+50----> 150° is not a triangle
therefore
That dimensions cannot create a triangle
case C. Three sides measuring 5 in,12 in,and 14 in
Applying the Triangle Inequality Theorem
5+12>14 -- > is ok
14+5>12 --- > is ok
12+14>5 --- > is ok
That dimensions can create only one unique triangle

A. 4.25 cm
B. 425 cm
C. 680 cm
D. 850 cm
E. 1700 cm
Answer:
Answers 425 is you multiply 50 by 8 you’d get 400 then add 25 the number 8 is the amount of times you can use the scale so it would be 16cm them you have one more cm left so you’d just cut the scale in half

A hyperbola is represented using the equation (x-1)^2/4-(y+2)^2/16=1. What are the slopes of the asymptotes?
Answer:
the slope of the asymptotes are: 2 and -2
Step-by-step explanation:
As we know the hyperbola equation is:
[tex]\frac{(x-h)^2}{b^2}-\frac{(y-k)^2}{a^2}=1[/tex]
Given the hyperbola equation:
[tex]\frac{(x-1)^{2} }{4} - \frac{(y+2)^{2} }{16} = 1[/tex]
We have a=2 and b=4, h=1 and k=-2
and the asymptote equation of a translate hyperbola with equation is:
[tex]y=\pm\frac{b}{a}(x-h)+k[/tex]
We substitute this values to get:
[tex]y=\pm\frac{4}{2}(x-1) -2[/tex]
<=> y = 2x -4 or y = -2x
so the slope of the asymptotes are: 2 and -2
Answer:
m=2

Assume markup is based on cost. Find the dollar markup and selling price for the following problem. (Round your answers to the nearest cent.)
Dollar markup
Selling price
Item
Burberry men's watch
Cost
$490
Markup percent
40%
Answer:
The selling price of the product = $686The markup of the selling price = 28.5 %Step-by-step explanation:
Given that the markup percent is based on the cost of the product.
The cost of Burberry men's watch = $490
Markup percent = 40 %
= 40 % (490) = $196
The new selling price of the product = 196 + 490 = $686
The markup percent of the selling price , (x%)686 = 196
x = 28.5 %
The markup is 28.5 % of the selling price
Final answer:
To calculate the dollar markup on a $490 item with a 40% markup, multiply the cost by 0.40 to get $196. The selling price is then the original cost plus the markup, totaling $686.
Explanation:
To find the dollar markup of a Burberry men's watch that costs $490 with a markup percent of 40%, you first need to convert the percentage to its decimal form by dividing by 100. This gives us 0.40. Next, you multiply the cost by the decimal form of the markup percentage to find the dollar markup.
Calculation:
$490 × 0.40 = $196
To find the selling price, add the dollar markup to the original cost.
Calculation:
$490 + $196 = $686
The dollar markup is $196, and the selling price for the Burberry men's watch is $686, both rounded to the nearest cent.

Answer:
x ≈ 7.2
Step-by-step explanation:
Given a tangent- secant from an external point to the circle, then
the the square of the measure of the tangent is equal to the product of the external part of the secant and the entire secant, that is
x² = 4(4 + 9) = 4 × 13 = 52 ( take the square root of both sides )
x = [tex]\sqrt{52}[/tex] ≈ 7.2 ( to the nearest tenth )
Rainforest data:

When using the formula zx =
x − μ
σ
for the z-score for the 11.7 data point:
Step-by-step explanation:
1. x= 11.7 μ = 7
2. z11.7 = 1.3
3. A
4. B
The value of the z-score is 1.33.
What is a z-score?The z-score is defined as the mean (average) values, measured in terms of standard deviations from the mean.
The formula is used to calculate z-score is;
Z-score = (X-μ)/σ
We have, mean = 7 and σ =3.522 and X is 11.7.
Substitute all the values in the formula;
Z-score = (X-μ)/σ
= (11.7-7)/3.52
= 4.7/3.52
= 1.33
Hence, the value of the z-score is 1.33.

A dentist was making note of his upcoming appointments with different aged patients and the reasons for their visits.
The probability that an appointment is with patients over 60 years old is 0.2, and the probability that it is for a broken tooth is 0.4.
What is the probability that a randomly chosen appointment is with patients over 60 years old or is for a broken tooth if those are independent events?
Answer:
.08
Step-by-step explanation:
40% of 20% is 8%
Final answer:
The probability of a randomly chosen dental appointment being with a patient over 60 years old or for a broken tooth is 0.52, given that the events are independent.
Explanation:
The probability that a randomly chosen appointment is with patients over 60 years old or is for a broken tooth, given that these are independent events, can be found by using the formula for the probability of the union of two independent events: P(A ∪ B) = P(A) + P(B) - P(A ∩ B). Since the events are independent, P(A ∩ B) is equal to P(A) × P(B).
In this case, P(patients over 60) = 0.2, and P(broken tooth) = 0.4. Since they are independent events, the probability of both occurring together is 0.2 × 0.4 = 0.08. Thus, the combined probability is 0.2 + 0.4 - 0.08 = 0.52.
The probability that an appointment is with a patient over 60 years old or for a broken tooth is 0.52, or 52%.
