Answer:
181cm²
Step-by-step explanation:
Given
Radius of a circle = 7.6cm
Area of the circle = \pi r²
Substitute
Area of the circle = 3.14(7.6)²
Area of the circle = 3.14(57.76)
Area of the circle = 181.3664cm²
Area of the circle to 3sf is 181cm²

Sally is 4 years older than Brody. Evelyn is 3 times older than Brody. If Brody's age is represented by x, create an expression that represents the total age of all three people.
A.4x+4
B. 5x
C.5x+4
D.7x
Answer:
Its C. 5x +4
Step-by-step explanation:
The expression that represents the total age of all three people is f(x) = 5x + 4.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Sally who is 4 years older than Brody. Evelyn is 3 times older than Brody.
Assume that Brody's age is represented by [x]. Then, the age of Evelyn will be (3x) and the age of Sally would be (x + 4). The expression that represents the total age of all three people is -
f(x) = x + (x + 4) + 3x = 5x + 4
f(x) = 5x + 4
Therefore, the expression that represents the total age of all three people is f(x) = 5x + 4.

Point VV is located at (-5,3)(−5,3) on the coordinate plane. Point VV is reflected over the yy-axis to create point V'V ′ . Point V'V ′ is then reflected over the xx-axis to create point V''V ′′ . What ordered pair describes the location of V''?V ′′ ?
Given:
Point V is located at (-5,3) on the coordinate plane.
It is reflected over the y-axis to create point V'.
Point V' is then reflected over the x-axis to create point V''.
To find:
The location of point V''.
Solution:
We have,
Point V= (-5,3)
If point V reflected over the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
[tex]V(-5,3)\to V'(5,3)[/tex]
If point V' reflected over the x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]V'(5,3)\to V''(5,-3)[/tex]
Therefore, the ordered pair (5,-3) describes the location of V''.
Answer:
5,3

Two supplementary angles that are 4x and 5x what is the value of x
Answer:
x = 20
Step-by-step explanation:
4x + 5x = 9x
9x = 180 (supplementary angles add up to 180 degrees)
Divide 180/9 = 20
Answer:
x = 20.
Step-by-step explanation:
Supplementary angles sum to 180, so:
4x + 5x = 180
9x = 180
x = 20.

Write a polynomial equation of degree 4 that has the following roots: -1 repeated three times and 4.
Answer:
[tex] {x}^{4} - {x}^{3} - {9x}^{2} - {11x}^{2} - 4 [/tex]
Step-by-step explanation:
Since the roots are -1,-1,-1 and 4 we can that as.
[tex](x + 1)(x + 1)(x + 1)(x - 4)[/tex]
x+1=0, x equal -1, and x-4=0 and x equal 4. Then apply the foil method to one at a time and you equal the answer above.

GOOD AT MATH!! PLEASE HELPPP
Answer:
B. 5
Step-by-step explanation:
Use the pythagorean theorem to solve: [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex].
[tex]a^{2}[/tex]+[tex]12^{2}[/tex]=[tex]13^{2}[/tex]
[tex]a^{2}[/tex]+144=169
Subtract 144 from 169.
[tex]a^{2}[/tex]-144=169-144
[tex]a^{2}[/tex]=25
Square root to get a.
[tex]\sqrt{a}[/tex]=[tex]\sqrt{25}[/tex]
a= 5

Subtract 4x2 – 7x +6 from 2x2 – 5x – 4. Express as a trinomial
Answer: -2x²+2x-10
Step-by-step explanation:
Rephrase the expression
Subtract 4x²-7x+6 from 2x²-5x-4
(2x²-5x-4)-(4x²-7x+6)
Expand parenthesis
2x²-5x-4-4x²+7x-6
Put like terms together
(2x²-4x²)+(7x-5x)-(4+6)
Combine like terms
-2x²+2x-10
