const2013 [10]3 years ago
4 0

Answer:

[0] real zeros

Step-by-step explanation:

You can use the discriminant of the quadratic formula which is b² – 4ac to determine the # of real zeros by knowing that:

  • 2 real zero(s) occur when b² – 4ac > 0.
  • 1 real zero(s) occur when b² – 4ac = 0.
  • 0 real zero(s) occur when b² – 4ac < 0.

Question 1:
If you know that 3 squares equals 7 circles and the squares are being counted by 3, then continue to count the circle by 3 until you get 25 circles.
Example:
3 Squares : 7 circles
4 squares : 10 circles
5 squares : 13 circles 
6 squares : 16 circles
7 squares : 19 circles
8 squares : 22 circles
9 squares : 25 circles       Add 9 squares to 3 = 12
You will have 12 squares when continues to count all the way to 25 circles.

Question 2:
Just multiply 14 by 28 and you will get your answer. Which is 3. The missing digit's 3. You can then check by doing 392 ÷ 14 to see if you get 28.

Calculus question, PLEASE HELP WITH THIS, due tonight!!
kotegsom [21]

Answer:

(a) f(0) = 1

(b) f(3) = 5 (I'm not sure about this one, it's either this or undefined)

(c) f(-2) = 3

(d) \lim_{x\to -3^+} f(x)=1

(e) \lim_{x \to -2} f(x)=1

(f) \lim_{x \to 1^-} f(x)=2

(g) \lim_{x \to 1} f(x)= DNE, because the limit of x--> 1 from the left is 2, and the limit from the right is 1. Because they don't approach the same value from both sides, the limit doesn't exist.

A triangle has two sides of length 13 and 15. What is the largest possible whole-number length for the third side?
Brilliant_brown [7]

Answer:

27

Step-by-step explanation:

The third side must be shorter than the other 2 sides added together.

13 + 15 = 28, so at most it can be 27 , since it needs a whole number

Complete the table of values for y = 2x-5
Marianna [84]

Answer:

Step-by-step explanation:

y = 2x-5

x= -2

y = 2(-2) -5 = -4 -5 = -9

x= 0

y = 2·0 -5 = -5

x= 1

y = 2·1 -5 = 2-5 = -3

x= 4

y = 2·4 -5 = 8 -5 = 3

x  |  -2      -1       0       1      2      3     4

-------------------------------------------------------

y |  -9      -7     -5      -3     -1       1     3
