Answer:
b
Step-by-step explanation:
find the domain and range of f(x)= -2x²+3
Answer is in pictures and work as well
Answer:
you need to know what domain and range mean... so remember domain is the input.... range is the output.. :)
Step-by-step explanation:
the input .. "x" in this case.. can be any number .. so the domain is all real numbers.
the output.. or range.. is limited.. b/c the square on the 'x" will always make that number positive.. and then it's multiplied by the negative 2.... so that term will always be negative. : | hmmmm so when is that squred term the smallest it can be? hmmm when it's zero... soooo this function will .. at it's greatest point be 3 and go down from there...
the range is from -∞ to 3
see? :)
Please give me the correct answer.Only answer if you're very good at math.

find the lenght of cd
Use the distance formula.
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]x_2=7\\x_1=3\\y_2=-8\\y_1=-2[/tex]
[tex]\sqrt{(7-3)^2+(-8-(-2))^2}[/tex]

≈7.2111...
So the answer is B! Hope this helped!
Can you help me and explain too :)

how many factors of 10 are in 10 of the third power?
Answer:2 times 5 equals 10
Step-by-step explanation:
"The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10." From ww.infoplease.com great resource
The required factor of 10 in 10 of the third power is 3.
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
Here,
10 of the third power = 10³
10³ = 10×10×10
The expression 10×10×10 has 3, 10's
Thus, the required factor of 10 in 10 of the third power is 3.

A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.
True or false??
Given:
The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."
To find:
Whether the given statement in true or false.
Solution:
Area of circle is
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is
[tex]A_1=\pi (r_1)^2[/tex]
The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:
[tex]r_2=1.5r_1[/tex]
The area of the new circle is
[tex]A_2=\pi (r_2)^2[/tex]
[tex]A_2=\pi (1.5r_1)^2[/tex]
[tex]A_2=2.25\pi (r_1)^2[/tex]
[tex]A_2=2.25A_1[/tex]
The area of the new circle is 2.25 times the area of the original circle.
Therefore, the given statement is false.

Given the system of equations, what is the value of the system determinant?
2x + y = 8

0-1
0-2
0-3
Given:
The system of equation is
[tex]2x+y=8[/tex]
[tex]x-y=10[/tex]
To find:
The value of the system determinant.
Solution:
If two equations of a system of equations are [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex], then the system determinant is
[tex]D=\left|\begin{matrix}a_1&b_1\\a_2&b_2\end{matrix}\right|[/tex]
[tex]D=a_1b_2-b_1a_2[/tex]
The given two equations are [tex]2x+y=8[/tex] and [tex]x-y=10[/tex].
Here, [tex]a_1=2,b_1=1,c_1=8, a_2=1,b_2=-1,c_2=10[/tex].
[tex]D=\left|\begin{matrix}2&1\\1&-1\end{matrix}\right|[/tex]
[tex]D=(2)(-1)-(1)(1)[/tex]
[tex]D=-2-1[/tex]
[tex]D=-3[/tex]
The value of the system determinant is -3. Therefore, the correct option is C.
