B is not a real number.
Real number are numbers that are rational (1, 2, 3, -7, -10 etc) and irriational (pi, 9.7582, 1/7, etc), and can be virtually any number, aside from imaginary numbers. Square roots consist of the same number squared, for example the square root of 9, is 3 or the square root of 10 is 3.162... Both of which are real numbers.
A.) The square root of 1, is 1. 1 is a real number.
B.) The square root of -4 is imaginary. There is no real number that can be squared to get -4.
C.) The square root of 16 is 4. 4 is a real number.
D.) The square root of 13 is 3.605... 3.605... is a real number.
Thus meaning your answer is B.

Find the coordinates of the point of intersection of all parabolas that have equation y=x2+px +q with p+q=2020. The point of intersection is
Answers
Answer:
(1,2021)
Step-by-step explanation:
P and q can vary subject to their sum being 2020.
Consider one parabola with p1 and q1 and another with p2 and q2.
y1=(x1)^2+(p1)(x1)+(q1)
y1=(x2)^2+(p2)(x2)+(q2)
At their intersection, the x and y coordinates are the same.
y1=y2=y
x1=x2=x
x^2+(p1)x+(q1)=x^2+(p2)x+(q2)
Solve for x
x(p1-p2)=q2-q1
x=(q2-q1)/(p1-p2)
Use the constraint that p+q=2020 to eliminate p1 and p2.
p1=2020-q1
p2=2020-q2
x=(q2-q1)/(2020-q1-2020+q2)
x=(q2-q1)/(q2-q1)
x=1
Substitute in the equation for y.
y=1^2+p(1)+q
y=2021
Mumuni Bawumia, a farmer sells 500 litres of fresh milk a day with a standard deviation of 35 litres. Given that the daily sales of fresh milk is normally distributed, what is the probability that the sales in any single day is:
a. Greater than 506 litres
b. Between 498 litres and 506 litres.
Answers
Answer:
a: 0.43194
b: 0.09084
Step-by-step explanation:
First construct the z values for 498 and 506.
[tex]z=\frac{x-u}{s}[/tex]
[tex]z(498)=\frac{498-500}{35}[/tex]=-0.05714
z(506)=(506-500)/35=0.17143
Check the cumulative normal distribution tables to find
P(x<=-0.05714)=0.47722
P(x<=506)=0.52278
These probabilities imply that
P(x>506)=1-P(x<=506)=1-0.52278=0.43194
P(498<=x<=506)=P(x<=506)-P(x<=498)=0.09084

6x-6y=23 find y when x=8
Answers
Answer:
y= 4.166
If rounded to the nearest tenth
y = 4.2
Step-by-step explanation:
6x - 6y = 23
x = 8
6x - 6y = 23 (Sub in the x with 8)
6(8) - 6y = 23
48 - 6y = 23 (Subtract each side by 48)
-6y = 23 - 48
-6y = -25 (Divide each side by -6)
y = 4.166
If rounded to the nearest tenth
y = 4.2

Juan wants to buy some protein bars and magazines for a trip.
He has decided to buy three times as many protein bars as
magazines. Each protein bar costs $0.70 and each magazine
costs $2.50. The sales tax rate on both types of items is 734%.
How many of each item can he buy if he has $20.00 to spend?
What Is the answer I don’t know
Answers
Answer:
HI there! I am really sorry if i get this wrong, but please apperciate!
Thank you! :)
Step-by-step explanation:
So I worked this out like this:
Protein bars: 0.70 * 3 = 2.1
Magezines: 2.50
734% are the taxes as it was written. 734% decimal version is 7.34.
This is what I did next:
7.34 plus 2.1 times 2 equals 18.88. So, you can buy 2 protein bars.
7.34 plus 2.50 times 2 equals 19.68. So, you can also buy 2 magazines!
I hope this helps! Let me know if this is wrong. Thanks and have a nice day!

Answer:
How was Pi discovered?
Here's a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation.
How is PI value calculated?
In some ways Pi (π) is a really straightforward number – calculating Pi simply involves taking any circle and dividing its circumference by its diameter. In fact if you search long enough within the digits of Pi (π) you can find any number, including your birthday.

An angle measures 12°. Find its complement. Do not include units in your answer.
Answers
Answer:
78
Step-by-step explanation:
complements = 90
x + 12 = 90
-12. -12
× = 78
If two angles are complementary,
then the sum of their measures is 90 degrees.
If two numbers add to 90, we can represent those numbers as x and 90 - x.
So we will call one of our angles x and its complement as 90 - x.
So we have 90 - 12 which is 78.
So the complement of a 12° angle is a 78° angle.
