Answer:
a = 9r²
Step-by-step explanation:
Given
r = [tex]\frac{\sqrt{a} }{3}[/tex] ( multiply both sides by 3 to clear the fraction
3r = [tex]\sqrt{a}[/tex] ( square both sides )
(3r)² = ([tex]\sqrt{a}[/tex] )²
9r² = a

two negative integers are 8 units apart on the number line and have a product of 308. which equation could be used to determine x, the smaller negative integer? x2 8x – 308
Answers
The equation that could be used to determine x is ([tex]x^{2}[/tex] + 8x - 308).
As per the question, the small integer is x. So, the large integer will be (x + 8).
Also, the question mentions that their product is 308. Representing the given information in mathematical equation form -
x (x + 8) = 308
Performing multiplication on Left Hand Side of the equation
x² + 8x = 308
Shifting 308 from Right Hand Side to the Left Hand Side of the equation. the equation that will form is -
x² + 8x – 308 = 0
On solving this quadratic equation, we will get the negative numbers, which will validate our formed equation.
x² + 8x – 308 = 0
x² + 22x - 14x – 308 = 0
x (x + 22) - 14 (x + 22) = 0
(x + 22) (x - 14) = 0
x = -22 and 14
Since the numbers are negative, hence, value of small number is -22.
Large number = -22 + 8
Large number = -14
Thus, the small and large number is -22 and -14.
Therefore, the correct equation is x² + 8x – 308 = 0.

Each face of a pyramid is an isosceles triangle with a 84° vertex angle. What are the measures of the base angles?
Need asappp!
Answers
Step by step
The base angles are the 2 congruent angles in an isosceles triangle.
Sum of the interior angles =180 degrees.
The vertex is 84, so we know one angle.
180 - 84 = 96
Since the base angles will be equal, we divide 96 by 2 = 48.
The base angles will each be 48 degrees.
5. Find the magnitude of 4i + 3j
Answers
Answer:
5Step-by-step explanation:
The magnitude of the complex number is expressed as;
|z| = √x²+y²
Given the complex number z = 4i+3j, x = 4 and y = 3
Substitute
|z| = √x²+y²
|z| = √3²+4²
|z| = √9+16
|z| = √25
|z| =5
Hence the magnitude is 5

Answers
Answer:
not sure what your question is but if youre trying to solve for the system of equations your awnser is (5,3/2)
Answer:
x= 5, y= 3/2
Step-by-step explanation:
5x -4y =19 (Equation 1)
x+ 2y=18 (Equation 2)
Using substitution method,
From equation(2),make x the subject of formula
x= 8-2y (Equation 3)
Substitute equation 3 into equation 1
5x -4y= 19
5(8-2y) -4y = 19
40 -10y -4y = 19
40-14y=19
Collect like terms
40-19=14y
21=14y
y= 21/14 = 3/2
Substitute for y in equation 3
x= 8 -2y
8- 2(3/2)
=8 -3
x = 5

there are 8 elements in a set a, there are 5 elements in a set b, and 3 elements of those are shared both a and b. how many elements are in union of a and b?
Answers
There are 10 elements in the union of A and B.
What is the union of A and B?
The union of A and B will contain all of the elements found in either A or B or both sets. The union of sets is represented by the set notation. To find the union of two sets A and B, use the union B formula. Simply putting all of A and B's elements in one set and removing duplicates yields the union.So, set A has 8 elements and set B has 5 elements.
Both have 3 elements in common. So, 3 + (8 - 3) + (5 - 3) = 3 + 5 + 2 = 10Therefore, there are 10 elements in the union of A and B.

James and Willis are both painting a room. James could complete it in 6 hours by himself. Together they can complete the room in 2 hours. How long would it take Willis to paint the room by himself?
Answers
Answer: Willis will take 3 hours to paint the room by himself.
Step-by-step explanation:
Given: Time taken by James to complete job by himself = 6 hours
Let Time taken by Willis to complete job by himself = t hours
Together they take 2 hours.
[tex]\dfrac{1}{6}+\dfrac{1}{t}=\dfrac{1}{2}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{2}-\dfrac{1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{3-1}{6}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{2}{6}\\\\\Rightarrow\ t=\dfrac{6}{2}\\\\\Rightarrow\ t=3[/tex]
So, Willis will take 3 hours to paint the room by himself.

If there are no Domain Restrictions, what is the domain?
Answers
Answer:
If there are no restrictions, the domain is all real numbers.
- infinity < x < infinity
Answer:
Step-by-step explanation:
Functions are a correspondence between two sets, called the domain and the range. When defining a function, you usually state what kind of numbers the domain (x) and range (f(x)) values can be. But even if you say they are real numbers, that doesn’t mean that all real numbers can be used for x. It also doesn’t mean that all real numbers can be function values, f(x). There may be restrictions on the domain and range. The restrictions partly depend on the type of function.
In this topic, all functions will be restricted to real number values. That is, only real numbers can be used in the domain, and only real numbers can be in the range.
