Step-by-step explanation:
the disc. is the part under the root in the general formula
which is equal b^2 - 4 x a x c
in this equation a = 1 " coefficient of x^2"
b = 0 "coefficient of x which isn't found here "
c = 12 " the absolute "
[tex]0^{2} - 4[/tex]×[tex]1[/tex]×[tex]12[/tex] = -4×12 = something i don't have a calculator
but it will be negative so the roots will be complex and unreal

A pizzeria sells a round pizza with a diameter of 16 inches.
Another pizzeria sells a large square pizza with a side length of 15 inches
Which has more crust along the outside edge of the pizza, the round pizza or the square pizza?
Answers
Answer:
Square pizza
Step-by-step explanation:
d = Diameter of round pizza = 16 inches
a = Side length of square = 15 inches
More crust means the edge length of the pizza is greater. Edge length is given by the perimeter.
Circumference or perimeter of the round pizza
[tex]C=\pi d\\\Rightarrow C=\pi\times 16\\\Rightarrow C=50.27\ \text{inches}[/tex]
Perimeter of the square is
[tex]P=4a\\\Rightarrow P=4\times 15\\\Rightarrow P=60\ \text{inches}[/tex]
So, the square pizza has more crust compared to the round pizza.

Answer:
A) y>=-1
Step-by-step explanation:
The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer
Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.

Required:
Determine the first step where she made mistake
Her Step 1:
[tex](3)^ 2 + 23 * 4[/tex] --- This is correct because she solved the bracket first
Her Step 2:
[tex]9 + 23 * 4[/tex] --- This is correct because she solved 3^2 as 9
Her Step 3:
[tex]9 + 9 * 4[/tex] --- This is incorrect because 23 * 4 is not equivalent to 9 * 4
Hence, her first mistake is in step 3.
The correct expression would have been
[tex]9 + 92[/tex]
Then

EXPENSES: Camille has no more than $50.00 to spend each week for lunch and bus fare. Lunch costs $3.00 each day, and bus fare is $1.75 each ride. Write an inequality for this situation. Can Camille buy lunch 7 times and ride the bus 14 times in one week????
Answers
Answer:
Inequality: [tex]3.00 L + 1.75B \leq 50[/tex]
She can afford to buy the lunch and bus rides
Step-by-step explanation:
Given
[tex]Maximum\ Amount = \$50.00[/tex]
[tex]Lunch = \$3.00[/tex] daily
[tex]Bus\ Fare = \$1.75[/tex] daily
Solving (a) The inequality
Let bus ride be represented with B and Lunch be represented with L
If 1 bus ride costs $1.75, then
B bus ride would cost $1.75 * B
If 1 lunch costs $3.00, then
L lunch would cost $3.00 * L
Total Spending is then the sum of the above expression i.e.
$3.00 * L + $1.75 * B
The question says Camille can not spend more than $50.00.
This is represented by less than or equal to.
So, the expression is:
[tex]3.00 * L + 1.75 * B \leq 50[/tex]
[tex]3.00 L + 1.75B \leq 50[/tex]
Solving (b): Can she afford 7 lunch and 14 bus ride?
To do this, we simply substitute 7 for L and 14 for B
[tex]3.00 * 7 + 1.75 * 14 \leq 50[/tex]
[tex]21 + 24.5 \leq 50[/tex]
[tex]45.5 \leq 50[/tex]
The above inequality is true.
Hence, she can afford to buy the lunch and bus rides

In a polar coordinate system, the midpoint of the line segment whose endpoints are $\left( 8, \frac{5 \pi}{12} \right)$ and $\left( 8, -\frac{3 \pi}{12} \right)$ is the point $(r, \theta).$ Enter $(r, \theta),$ where $r > 0$ and $0 \le \theta < 2 \pi.$
Answers
Answer:
Step-by-step explanation:
Given the coordinate points (8, 5π/12) and (-3, π/12)
The midpoint is expressed using the formula
M(X,Y) = {(x1+x2)/2, (,y1+y2)/2}
X = x1+x2/2
X = 8-3/2
X = 5/2
Y = y1+y2/2
Y = (5π/12+π/12)/2
Y = (6π/12)/2
Y = 6π/24
Y = π/4
Hence the required coordinate is at(2.5, π/4)

The kingdom of Arendelle is trying to decide who to send to the regional track meet. Anna, Elsa, and Olaf competed in the long jump and their 6 jumps are shown below (in meters). Kristoff says that Olaf has the longest average, so he should be sent to the track meet. Do you agree or disagree? Why?
Answers
Please find table attached
Answer:
Agree: Olaf should be sent to the track meet because he has the longest average
Step-by-step explanation:
To ascertain if this is true, we must calculate the average for each athlete
Mean or average of athlete= total score of jumps/ number of jumps
Average for Anna= 3.25+3.95+4.28+2.95+3.66+3.81/6 = 3.65
Average for Elsa=3.55+3.88+3.61+3.97+3.75+3.59/6
=3.725
Average for Olaf=3.67+3.78+3.92+3.62+3.85+3.73/6
= 3.76
Therefore Olaf has the longest average =3.76

Solve this system of equations: 3x-2y=2 5x-5y=10
Answers
Answer:
(- 2, - 4 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 2 → (1)
5x - 5y = 10 → (2)
Multiply (1) by 5 and (2) by - 3, then add to eliminate x
15x - 10y = 10 → (3)
- 15x + 15y = - 30 → (4)
Add (3) and (4) term by term to eliminate x , that is
5y = - 20 ( divide both sides by 5 )
y = - 4
Substitute y = - 4 into either of the 2 equations and solve for x
Substituting into (1)
3x - 2(- 4) = 2
3x + 8 = 2 ( subtract 8 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Solution is (- 2, - 4 )
