plugged in the answers into (x) and (y)
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.

Answers
Answer:
7.9 m
Step-by-step explanation:
Use the Pythagorean theorem: a²+b²=c²
This formula can be used to solve a side of any right (90°) triangle.
c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)
So, c = 32m.
Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:
31² + b² = 32²
961 + b² = 1024 Subtract 961 from both sides to get b² by itself.
b² = 63
√b² = √63 Square root both sides to get b by itself.
b = 7.93725
Answer is 7.9 meters, rounded to tenths place

Find the Area ( PLEASE LEAVE EXPLANATION)
Answers
Answer:
28 ft²
Step-by-step explanation:
Hello There!
To solve for the area of an irregular shape we want to split the irregular shape into regular shapes
For this irregular shape we would split it into a square with a side length of 2ft and a rectangle with a length of 6ft and a width of 4ft ( width was found subtracting total height of irregular figure (6ft) from height of square (2ft) 6ft - 2ft = 4ft so the width would be 4ft)
now we can easily solve for the area of each individual shape
area of square -
the area of a square can simply be found by raising the side length to the power of 2
so
[tex]a =2^2\\2^2=4\\a=4ft^2[/tex]
so we can conclude that the area of the square is 4ft^2
Now we want to find the area of the rectangle
the area of a rectangle is simply equal to the width times the length
so
[tex]a=6*4\\6*4=24\\\\a=24ft^2[/tex]
so we can conclude that the area of the rectangle is 24ft^2
Finally we add the two areas together
24 + 4 = 28
thus meaning the area of the irregular figure is 28 ft²

Find cosθ, tanθ, and cscθ, where θ is the angle shown in the figure.
Give exact values, not decimal approximations.
Answers
Answer:
Cos(θ) = 7/√58 ; Tan(θ) = 3/7 ; Csc(θ) = √58/3
Step-by-step explanation:
First, let's solve for the hypotenuse by using the Pythagorean Theorem.
a² + b² = c²
⇒ 7² + 3² = c²
⇒ 49 + 9 = c²
⇒ 58 = c²
⇒ √58 = c
Now that we know the hypotenuse is √58, we can solve for the trig ratios.
Cos(θ) = adjacent/hypotenuse = 7/√58
Tan(θ) = opposite/adjacent = 3/7
Csc(θ) = hypotenuse/opposite = √58/3

Find the exact values of the remaining five trigonometric functions of o satisfying the given conditions.
cos θ=3/5, tan θ < 0
Answers
First, tan(θ) = sin(θ) / cos(θ), so if cos(θ) = 3/5 > 0 and tan(θ) < 0, then it follows that sin(θ) < 0.
Recall the Pythagorean identity:
sin²(θ) + cos²(θ) = 1
Then
sin(θ) = -√(1 - cos²(θ)) = -4/5
and so
tan(θ) = (-4/5) / (3/5) = -4/3
The remaining trig ratios are just reciprocals of the ones found already:
sec(θ) = 1/cos(θ) = 5/3
csc(θ) = 1/sin(θ) = -5/4
cot(θ) = 1/tan(θ) = -3/4
