The points (0, 0), (-1, -1), and (1,-2) inside the conic inequality option (B), (C), and (E) are correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
Conic inequality:
8x² – 12x + 4y² + 4y – 20 ≤ 0
After plotting the above inequality on a coordinate plane we will get an ellipse:
From the graph:
The points:
(0, 0), (-1, -1), and (1,-2) inside the conic inequality.
Thus, the points (0, 0), (-1, -1), and (1,-2) inside the conic inequality option (B), (C), and (E) are correct.

Answer:
16 m
Step-by-step explanation:
The useful trig relation is ...
Sin = Opposite/Hypotenuse
sin(41°) = a/(25 m)
a = (25 m)sin(41°) ≈ 16.40 m
The measure of side 'a' is about 16 meters.

Answer:
4 pairs of sock and a little bit of left over change.
Step-by-step explanation:
24.95 + 5.95x = 50
-24.95 -24.95
5.95x=25.05
/5.95 /5.95
x = 4.21
We drop the 0.21 because you cant have 0.21 pairs of socks and we get:
x=4
Answer:
About 4 pairs.
Step-by-step explanation:
50.00-24.95=25.05
5.95x5=29.75 (that is more the 25.05, so no.)
5.95x4=23.80 (Its a little bit less but not higher than the number we have left to spend.)

4x/4x=177/4x
0.225989
Answer:
=78 degrees
Step-by-step explanation:
complementary angles add up to 90 degrees
A + B = 90
3x + 9 + x - 11 = 90
3x + x + 9 - 11 = 90
4x - 2 = 90
collect like valuables
4x = 90 + 2
4x = 92
x =23
angle A = 3x + 9
= (3 x 23) + 9
= 69 + 9
= 78

find the length of the bold arc. Round your answer to the nearest tenth.
Answer:
The length of the bold arc is approximately 13.4 mi
Step-by-step explanation:
The radius of the circle having the arc, r = 17 mi
Therefore, the circumference of the circle, 'C', is given as follows;
C = 2·π·r
∴ C = 2×π×17 = 34·π
The angle subtended by the arc = 45°
The sum of the angles at the center of the circle = 360°
By similarity, the ratio of the length of the bold arc to the circumference of the circle = The ratio of the angle subtended by the arc to the sum of the angles at the center of the circle
Mathematically, we have;
[tex]\dfrac{The \ arc \ length}{C} = \dfrac{\theta}{360^{\circ}}[/tex]
Therefore, we get;
[tex]\dfrac{The \ arc \ length}{34 \cdot \pi} = \dfrac{45 ^{\circ}}{360 ^{\circ}} = \dfrac{1}{8}[/tex]
[tex]{The \ arc \ length}{} = \dfrac{1}{8} \times 34 \cdot \pi = 4.25 \cdot \pi[/tex]
The length of the bold arc = 4.25·π mi ≈ 13.4 mi (by rounding off the answer to the nearest tenth).

An appliance is for sale at either (a) P15,999 cash or (b) on terms, P1,499 each month for the next 12 months. Money is 9% compounded monthly. Which is lower, the cash price or the present value of the installment terms? Explain.
Answer:
Cash price
Step-by-step explanation:
The computation is shown below:
The Interest rate per month (r) = (9% ÷ 12) = 0.75%
Now Present value of the monthly payment is
= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}
= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}
= 18,748.89
And the cash price is 15,999
So, the cash price would be lower
The cash price would be lower. A further explanation is below.
According to the question,
Interest rate per month,
[tex]r = \frac{9 \ percent}{12}[/tex]
[tex]= 0.75[/tex] (%)
hence,
The Present value of the monthly payment will be:
= [tex]PMT\times \frac{{(1 + Interest \ rate)^{number \ of \ years} - 1}}{Interest \ rate}[/tex]
= [tex]1499\times \frac{[(1 + 0.75 \ percent)^{12} - 1] }{0.75 \ percent}[/tex]
= [tex]18748.89[/tex]
As we can see that the cash price is 15,999. Thus the above answer is right.
