Answer:
Scalene triangle, right triangle.
Step-by-step explanation:
To find out what type of triangle this is, we have to find x, so we set up an equation:
The sum of interior angles in a triangle add up to 180°
(2x + 15°) + (4x - 10°) + (x) = 180°
Open paranthesis:
2x + 15° + 4x - 10° + x = 180°
Combine like terms:
7x + 5° = 180°
Same to both sides
7x = 175°
x = 25°
We plug in x for each of the values:
2(25°) + 15° = 65°
4(25°) - 10° = 90°
25° = 25°
Because none of the angles are equal, that makes this triangle a scalene triangle, and since one of the angles is a 90° angle, that makes this triangle a right triangle

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) = x2 to the number of x-intercepts in the graph of g(x) = x2 +1. Be sure to include the transformations that occurred between the parent function f(x) and its image g(x).
Answers
Answer: The graph of f(x) = x^2 will have only one x-intercept (0,0) since it is a parabola that opens upward and its vertex is at the origin. On the other hand, the graph of g(x) = x^2 +1 is a transformation of the parent function, the graph of f(x) = x^2, where the function was shifted up by 1 unit. Therefore this function g(x) = x^2 +1 will not have any x-intercept because when x=0 the y value becomes 1 so the x-intercept will not be on the x-y plane.
In summary, the graph of f(x) = x^2 has one x-intercept, while the graph of g(x) = x^2 +1 has no x-intercepts due to the transformation of the parent function.

How do you identify the base and exponent in an exponential notation?
Answers
We can identify the base and its exponent as the exponent indicates the number of times the base is used as a factor in an exponential notation.
What is Exponent ?An exponent is the number of times a number has been multiplied by itself. For instance, the phrase 2 to the third, which is represented as 23, means 2 x 2 x 2 = 8, not 23, and 2 x 3 = 6, respectively. Remember that every number multiplied by one is equal to itself.
Exponents are a technique of expressing extremely large numbers in terms of powers. The number of times a number has been multiplied by itself is the exponent, so to speak. For instance, the result of multiplying the number 6 by itself four times is 6 6 6 6. This can be expressed as 6⁴. Here, the exponent and base are 4 and 6, respectively.
An exponential number takes the shape of a, where an is multiplied by itself n times. The simple example is 8=23=222. In exponential notation, A is referred to as the base, whereas n is referred to as the power, exponent, or index. In scientific notation, 10, which is a specific illustration of exponential numbers, is typically always used as the base number.
Exponential notation make it easy to express powers succinctly. The exponent displays the base's multiplicative power. It can be written as 2 2 2 2=25 for the integer 32 because 2 is the "base" and 5 is the "exponent." The correct translation of this phrase is "two to the fifth power."

Value of gof(-1) is 2. The solution has been obtained by applying the multiplication operation on the given functions.
What are operations on functions?
Just like we add, subtract, multiply and divide the terms in a function, the functions can also be added, subtracted, multiplied or divided in a similar way.
Suppose there are two functions f(x) and g(x). The notations are as follows:
For Addition: (f+g)(x) = f(x) + g(x)For Subtraction: (f-g)(x) = f(x) - g(x)For Multiplication: (f×g)(x) = f(x) × g(x)For Division: (f/g)(x) = (f(x))/(g(x))Now, gof= g(f) = 3-f
We are given f = 2+x
So, f(-1) = 2+(-1) = 1
Now, substituting the value of f(-1) in g(f) , we get
gof(-1)= 3-1=2
Hence, the value of gof(-1) is 2.

What is linear equation ?
Linear equation can be defined as equation in which highest degree is one.
In order to determine the equation for this relationship, we need to first find the slope between these two values. There are two ways to do this:
1. Create a graph
*Create a graph with the x-axis representing the years past 2000 (so 2000 would be 0 and 2003 would be 3 and so on)
*Use the fact that slope=rise/run to get slope=2.7/3 (because we rise 87-84.3=2.7 and run 3 (from 2000 to 2003), and 2.7/3=27/30=9/10
*Plug this and the point (0, 84.3) into the formula y=mx+b to find the y-intercept of your equation
--> 84.3=(9/10)(0)+b --> b=84.3
So, your equation can be written now as y=(9/10)x+84.3
[Note: To check, if you plug in 3 you should get 87, and you do, so it works!]
2. Use the slope formula
Alternatively, you could have did slope=(y2-y1)/(x2-x1)=(87-84.3)/(3-0)=2.7/3=9/10
The process here would be the same as above
b) Here, just plug 10 into the equation above (since 10 is the number of years 2010 is after 2000, or 2010-2000=10). Doing this we get:
y=(9/10)(10)+84.3=9+84.3=93.3
So, in 2006 we have 93.3 people per sq mile
Therefore, In 2006 we have 93.3 people per sq mile .

What is a triangle?
A triangle is a three-edged polygon with three vertices. It is a fundamental shape in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.
Given that ΔTUV is a triangle with m∠T=99° and m∠U=53°.
The length of t is 70 inches.
The opposite side of ∠T is t, the opposite side of ∠U is u, and the opposite side of ∠V is v.
Sine rule of ΔABC:
a/sin A = b/sin B = c/sin C
Apply sine law in ΔTUV:
t/sin T = u/sin U = v/sin V
Putting ∠T=99°, ∠U=53°, and t = 70.
70/ sin 99° = u/sin 53°
u = (70sin 53°)/ sin 99°
u = 56.60 inches
The digit after the decimal point is greater than 5, thus add 1 with the 56 to get the nearest inch.
u = 57 inches

which of the following is not the solution of 3x+6y=12?A) (-4,4) B) (0,2)C) (8,-2)D) (3,1)
Answers
(3,1) is not the solution of the equation 3x + 6y = 12. So the option D is correct.
In the given question, we have to check which of the following is not the solution of 3x+6y=12.
To check which is not the solution of the given equation, we put the value of x and y from the given point. If for any point the condition is true then that point is the solution of the given equation. If that point doesn't satisfy the condition then that point is not the solution of the given equation.
The given equation is 3x+6y=12.
Firstly we check for the point (-4,4), where x = -4, y = 4
3(-4) + 6(4) = 12
-12 + 24 = 12
12 = 12(True)
Now we check for the point (0,2), where x = 0, y = 2
3(0) + 6(2) = 12
0 + 12 = 12
12 = 12(True)
Now we check for the point (8,-2), where x = 8, y = -2
3(8) + 6(-2) = 12
24 - 12 = 12
12 = 12(True)
Now we check for the point (3,1), where x = 3, y = 1
3(3) + 6(1) = 12
9 + 6 = 12
15 = 12(False)
Hence, (3,1) is not the solution of the equation 3x + 6y = 12. So the option D is correct.

Probability of being a senior or white
Answers
The probability of being a senior citizen and white is: (0.63)(0.3) = 0.189.
What is probability?Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty.
Given that the probability of identifying white is 0.63.
Then the probability of not white is:
1 - 0.63 = 0.37
Given that the probability of being a senior citizen is 0.3.
Then the probability of not a senior citizen is:
1-0.3 = 0.7
Hence, the probability of being a senior citizen and white is:
(0.63)(0.3) = 0.189

How do you find a prime number multiples?
Answers
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A prime number can only be divided evenly by 1 and itself.
To find the multiples of a prime number, you can use the following steps:
Start with the prime number itself. This is the first multiple of the prime number.Multiply the prime number by 2. This will give you the second multiple of the prime number.Multiply the prime number by 3. This will give you the third multiple of the prime number.Repeat step 3 for larger and larger integers (4,5,6,7,8....) until you reach the desired number of multiples.For example, if the prime number is 5, the multiples of 5 are 5, 10, 15, 20, 25, and so on.

No, it is not possible to have a triangle with sides of 2cm, 2cm, and 5cm.
