The hospital uses the quadratic model to predict the number of births
The equation of the quadratic model is f(x) = 4 x^2 -43 x +178, and the number of births for month 8 is 90
How to determine the quadratic modelTo determine the quadratic model, the make use of a graphing calculator, that has the following calculation summary
a = 4.339 b = -43.461 c = 178.3A quadratic model is represented as:
[tex]y= ax^2 + bx + c[/tex]
So, we have:
[tex]y = 4.339 x^2 -43.461 x +178.3[/tex]
Approximate
[tex]y = 4 x^2 -43 x +178[/tex]
Rewrite as:
[tex]f(x) = 4 x^2 -43 x +178[/tex]
At the 8th month, we have x = 8.
So, the function becomes
[tex]f(8) = 4 * 8^2 -43 *8 +178[/tex]
[tex]f(8) = 90[/tex]
Hence, the number of births for month 8 is 90

When the doctor evaluates the nares, what finding could not be appreciated?
Answer:
Heart sounds
Step-by-step explanation:
Your doctor has allergic reaction, febrile rash, and meningitis in their differential for the patient.In a healthy adult, the heart makes two sounds, commonly described as 'lub' and 'dub. ' The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.Which equation is equivalent to startroot x squared 81 endroot = x 10? x 9 = x 10 x 9 = x2 20x 100 x2 81 = x2 100 x2 81 = x2 20x 100
The equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The equation is given below.
[tex]\rm \sqrt{x^2 + 81} = x + 10[/tex]
Squaring both sides, we have
[tex]\rm (\sqrt{x^2 + 81})^2 = (x + 10)^2\\\\x^2 \ \ +\ \ 81 \ \ = x^2 + 20x + 100[/tex]
Thus, the equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.

Answer:
the exact answer is in decimal ... 15.714 is the value of x
In the addition problem below, the digits B and C represent a number different from any of the other numbers shown (that is, not 1, 4, 5, 6, or 9. B5+C9=164
B5 + C9 = 164
Split the numbers.
B0 +C0 +14 = 164.
B0 + C0 = 150
B + C = 15
B cannot be 1, 2, 3, 4, or 5 because that forces C to be a two digit number and C only represents 1 digit.
B cannot be 6 or 9 because they are present.
B can only be 7 or 8. C can also be 7 or 8.
Therefore, B = 7 and C = 8, OR B = 8 and C = 7.

The equation y = 3x - 5 is an illustration of a linear equation
The slope is 3, and the y-intercept is -5
How to complete the table?The equation of the table is given as:
y = 3x - 5
When x = -1, we have:
y = 3(-1) - 5 = -8
When x = 0, we have:
y = 3(0) - 5 = -5
When x = 1, we have:
y = 3(1) - 5 = -2
So, the complete table is:
x y

The slope and the y-interceptA linear equation is represented as:
y = mx + b
Where:
m represents the slope and b represents the y-intercept.
By comparison, we have:
m = 3, and b = -5

Hey there!
The first expression is
5x+15
The equivalent expressions are
5(x+3)
- the opposite of the Distributive Property: 5(x+3)=5x+15
Plus
isn't 5*x+5*3 the same as 5x+15?
Yeah, it is :)
Hence, the equivalent expressions are
[tex]\boxed{\boxed{\bold{Option\;A \;and\;Option\;B}}}[/tex]
[tex]\rule{200}{2}[/tex]
In order to simplify this expression, we need to combine like terms:
11+12y-3-y
The y's are like terms:
11+12y-y-3
11+11y-3
Can you spot any other like terms here? That's right, 11 and -3:
11-3+11y
8+11y
Hence, the equivalent expression is
