No x- intercept/Zero

Step-by-step
F(x) = 3x^2 + 2x + 10
To find x-intercept/zero, Substitute
F(x) = 0
0 = 3x^2 + 2x + 10
Swap the side of the equation
3x^2 + 2x + 10 = 0
Solve the quadratic equation
ax^2 +b+c = 0
X= -b+ b^2 -4 a c/ 2a
X= -2+ 2^2 -4 x 3 x 10/2x3
X= -2+ 4-4 x 3 x 10/ 2 x 3
-> x=-2+ 4-120/2 x 3 -> x=-2 4-120/6
X=-2+ -116/6
-> calculate the difference
X= -2+ -116/6
The square root of a negative
number dose not exit in the set of
Real numbers
No x-intercept/zero

emma will roll two number cubes labeled 1 through 6. She will record the sum of the two numbers after each roll. She will roll t

SashulF [63]

Answer:

75 times

Step-by-step explanation:

First of all let's ook at the 36 possible outcomes and their sums.

2=1,1

3=1,2 2,1

4=1,3 ; 2,2 ; 3,1

5=1,4 ; 2,3 ; 3,2 ; 4,1

6=1,5 ; 2,4 ; 3,3 ; 4,2 ; 5,1

7=1,6 ; 2,5 ; 3,4 ; 4,3 ; 5,2 ; 6,1

8=2,6 ; 3,5 ; 4,4 ; 5,3 ; 6,2

9=3,6 ; 4,5 ; 5,4 ; 6,3

10=4,6 ; 5,5 ; 6,4

11=5,6 ; 6,5

12=6,6

Looking at the above, there are 4 sums equal to 5 out of a total of 36 sums.

Thus, probability of getting a sum equal to 5 is;

P(5) = 5/36

Now,since the cubes are rolled 540 times, number of times a sum equal to 5 will appear will be;

(5/36) x 540 = 75 times

How much will you pay in all for the $78 lunch bill with a 15% tip ?

Sergeeva-Olga [200]

→ You will pay $ 89.7.

The tip value is based on the bill value. Hence, to find the total payment you have to <u>multiply 78 by 1.15</u> (this includes the tip, 1.15).

$\Large \text {$Total = 78 \times 1.15 = 89.7 $}$

Or you can <u>first find how many</u> 15% is from $78:

$\Large \text {$0.15 \times 78 = 11.7$}$

And then add this to $78:

$\Large \text {$78 +11.7 = 89.7$}$
