Name the property the equation illustrates.
8.2 + (–8.2) = 0
Answer:
The name of the property the equation illustrates is the Inverse Property of Addition.
Step-by-step explanation:
The Inverse Property of Addition says that if you add a number to the negative version of itself, the numbers will cancel out and the result will be 0. In other words, if you add 8.2 + (–8.2), the answer will always be 0.

You are standing above the point (5,4)(5,4) on the surface z=15−(2x2+3y2)z=15−(2x2+3y2). (a) in which direction should you walk to descend fastest? (give your answer as a unit 2-vector.)
To descend fastest from the point (5,4) on the surface z=15-(2x^2+3y^2), you should walk in the direction of the negative gradient vector, normalized to be a unit vector, which is approximately <0.640, 0.768>.
Explanation:To determine the direction in which you should walk to descend fastest from the point (5,4) on the surface z=15-(2x^2+3y^2), we can find the gradient of the surface at that point. The gradient vector will point in the direction of the steepest ascent, so the direction of the steepest descent is the opposite direction of the gradient vector.
First, calculate the partial derivatives of z with respect to x and y:
∂z/∂x = -4x
∂z/∂y = -6y
Next, evaluate these derivatives at the point (5,4):
∂z/∂x(5,4) = -4(5) = -20
∂z/∂y(5,4) = -6(4) = -24
The gradient vector at (5,4) is <-20, -24>. To get the direction of steepest descent, we take the negative of the gradient vector, which is <20, 24>.
Finally, normalize this vector to make it a unit vector (so it has a length of 1):
Length of gradient vector = √(20^2 + 24^2) = √(400 + 576) = √976 ≈ 31.24
The unit vector in the direction of steepest descent is <20/31.24, 24/31.24> ≈ <0.640, 0.768>.

What is the factored form of 6x2 + 11x – 10? (2x + )( x – )
Answer:
[tex]6x^2+11x-10=(2x+5)(3x-2)[/tex]
Step-by-step explanation:
we are given
[tex]6x^2+11x-10[/tex]
We can factor it
[tex]6x^2+11x-10=6x^2+15x-4x-10[/tex]
we can use grouping method
[tex]6x^2+11x-10=(6x^2+15x)-(4x+10)[/tex]
now, we can take out common terms
[tex]6x^2+11x-10=3x(2x+5)-2(2x+5)[/tex]
we can take 2x+5 from both terms
[tex]6x^2+11x-10=(2x+5)(3x-2)[/tex]
so, we get factor terms as
[tex]6x^2+11x-10=(2x+5)(3x-2)[/tex]
The factored form of 6x² + 11x - 10 is: (2x + 5)(3x - 2)
Factorization of Algebraic ExpressionsGiven the algebraic expression, 6x² + 11x - 10, it can be factorized as shown in the steps below:
6x² + 11x - 10
6x² + 15x - 4x - 10
(6x² + 15x) - (4x - 10)
3x(2x + 5) - 2(2x + 5)
6x² + 11x - 10 = (2x + 5)(3x - 2)
Therefore, the factored form of 6x² + 11x - 10 is: (2x + 5)(3x - 2).

Find the measure of SMK
A) 36°
B) 48°
C) 56°
D) 66°
The required measure of ∠SMK is 66° for the given figure.
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.
The figure is given in the question, as shown.
According to the given figure, we have
In triangle ΔAMS,
∠ASM + ∠SAM + ∠AMS = 180° (sum of the interior angle)
36° + 30° + ∠AMS = 180°
∠AMS = 180° - 66°
∠AMS = 114°
∠SMK + ∠AMS = 180° (Supplementary angles)
∠SMK + 114° = 180°
∠SMK = 180° - 114°
∠SMK = 66°
Thus, the measure of ∠SMK is 66°.

Which equation can be used to find the number of wolves in the state on January 1? A zoologist is recording the loss of wolves in her state. She notes the number of wolves, w, in the state on January 1. One year later, there were 84 wolves in the state, which is 23 fewer wolves than were in the state a year earlier. What is the number of wolves in the state on January 1? w−84=−23 w−23=84 23−w=84 w + 23 = 84
Answer: w - 23 = 84

he average distance between Jupiter and the sun is 7.8 × 108 kilometers, and the average distance between the sun and Neptune is 4.51 × 109 kilometers. What is the approximate difference between these average distances?
Final answer:
The approximate difference between the average distances from the Sun to Jupiter and from the Sun to Neptune is approximately [tex]-3.71 * 10^9 km.[/tex]
Explanation:
The approximate difference between the average distances from the Sun to Jupiter and from the Sun to Neptune can be found by subtracting the average distance to Neptune from the average distance to Jupiter.
Average distance to Jupiter: 7.8 × 108 km
Average distance to Neptune: 4.51 × 109 km
Subtract the average distance to Neptune from the average distance to Jupiter:
[tex]= 7.8 * 10^8 km - 4.51 * 10^9 km[/tex]
= [tex]-3.71 * 10^9[/tex]
The approximate difference between the average distances is [tex]-3.71 * 10^9 km.[/tex]

A high school basketball team scores 85 points in a playoff game. The team leaders are Greg and Tremaine who scored a total of 38 points. If Tremaine scored 8 more points than Greg, how many points did Greg and Tremaine score individually?
Answer:
Total Points scored by team leaders are Greg and Tremaine=38 points
Let Points scored by Greg =x points
Then , Points scored by Tremaine =(x+8) points
So, writing the condition in equality form
x +x+8=38
2 x =38-8
2 x=30
Dividing both sides by ,2
x=15
Points scored by Greg =15 points
Then , Points scored by Tremaine =(15+8)=23 points
