Select a setting so that each given point will lie within the viewing window.
(-13,3), (0,0).(-2,-7)
Answers
Answer:
The given points are
[tex](-13,3)\\(0,0)\\(-2,-7)[/tex]
The setting would have a interval or 2 units above and below the minimum and maximum of each coordinate.
The given maxium horizontal coordinate is 0.
The given minimum horizontal coordinate is -13.
The given maximum vertical coordinate is 3.
The given minimum vertical coordinate is -7.
Now, we extend each maximum and minimum value by 2 units to create the setting.
So, the setting is
[tex]x_{min}=-15\\x_{max}=2\\ y_{min}=-9\\y_{max}=5[/tex]
With a scale of 2 units.

Morgan has 5 blue t-shirts , 3 green t-shirts and 2 red t-shirts . She randomly picks a shirt. What is the probability of choosing each color?
Answers
Answer:
Confusing question but I think it's 10:10
Step-by-step explanation:
Total outcome = 5:3:2
= 5+3+2
=10.
Probability = number of success
Total outcome
= 10/10
Therefore the probability of Morgan choosing each colour is 10:10.

Answers
Answer:
The answer is 7.96×10⁷ .
Step-by-step explanation:
As the decimal moves to the left , you have to add one more power to the base 10 :
e.g
7 960 000.0 = 7 960 000×10¹
796 000.00 = 796 000×10²
79 600.000 = 79 600×10³
7 960.0000 = 7 960×10⁴
796.00000 = 796×10⁵
79.600000 = 79.6×10⁶
7.9600000 = 7.96×10⁷

The three inside angles (A,B and C) of a right angled triangle are in the ratio 7:18:11
the smallest angle is 35 degrees
work out angles A,B and C
Answers
This is overdetermined. Without looking at the ratio (except for the order of the sides) the actute angles in a right triangle are complementary so the answer must be:
Answer: A=35°, C=90°, B=55°
We can do it the way they like.
7+18+11 =36
so to get 180 degrees we need to scale the ratio elements by a factor of 5.
7:18:11=35:90:55
A is the smallest. We see C is indeed a right angle and B is complementary to A.

Answer:
3/25
Step-by-step explanation:
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(green) = number of green / total = 4/10 = 2/5
We replace it
3 red marbles, 4 green marbles, and 3 blue marbles = 10 marbles
P(red) = number of red / total = 3/10
P(green, replace,red) =2/5*3/10 = 3/25

Answer:
(2x-5)(3x-2)
Step-by-step explanation:
1)When factoring quadratic equations in for ax²+bx+c you need to separate the b term in a way that the two addends you separate it by should equal a•c. Just do trial and error. In this case you should get -4 and -15. Your separated equation should be:
6x²-4x-15x+10
2)now factor out a common factor from the first two terms and one from the last two terms you should have:
2x(3x-2)-5(3x-2)
3)finally rewrite this equation into two separate factors and you have your answer.

y=0.03x+1
1:A and D
2:B and C
3:A and C
4:C and D
Answers
Answer:
Option 3
Step-by-step explanation:
All equations are in slope-intercept form. [tex]y=mx+b[/tex]
The 'm' is the slope.
The 'b' is the y-intercept.
The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.
Let's look over the equations:
Equation A:[tex]y=0.3x-6[/tex]
In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
Equation B:[tex]y=3x-8[/tex]
In this equation, 3 replaces 'm', so the rate of change for this equation is 3.
Equation C:[tex]y=0.3x+4[/tex]In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
Equation D:[tex]y=0.03x+1[/tex]In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.
Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.

Define dot product, inner product, cross product.
Answers
Answer:
Dot product. ... In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used and often called "the" inner product (or rarely projection product) of Euclidean space even though it is not the only inner product that can be defined on Euclidean space; see also inner product space.
Step-by-step explanation:
Answer:
- A dot product is the product of the magnitude of the vectors and the cos of the angle between them.
- A cross product is the product of the magnitude of the vectors and the sine of the angle that they subtend on each other.
- An inner product is a generalization of the dot product.
Step-by-step explanation:
Dot product - the sum of the products of the corresponding entries of the two sequences of numbers. Geometrically, it is the product of the Euclidean magnitudes of the two vectors and the cosine of the angle between them. These definitions are equivalent when using Cartesian coordinates.
Cross Product - The cross product is a mathematical operation which can be done between two three-dimensional vectors. It is often represented by the symbol. After performing the cross product, a new vector is formed. The cross product of two vectors is always perpendicular to both of the vectors which were "crossed".
Inner product - In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar.
