A table of values, rounded to the nearest hundredth, for the function
Answer:
Omggg twins I'm doing the Iready too:> Anyway I had that question and I selected 1.62
The average rate of change of function [tex]y= \sqrt[3\\]{x}[/tex] over interval [2,7] to rounding to nearest hundredth is 0.13
The Correct option is (b)
What average function?The Average Rate of Change function is defined as the average rate at which one quantity is changing with respect to something else changing.
i.e., [tex]\frac{f(b)- f(a)}{b-a}[/tex]
It has been asked in the question the average rate of function over interval [2,7].
The values are given in the table.
So, the rate of change of f(x) on interval [a, b] = [tex]\frac{f(b)- f(a)}{b-a}[/tex]
we have, a=2 and b=7
Thus, [tex]\frac{f(b)- f(a)}{b-a}[/tex] = [tex]\frac{\sqrt[3]{7} -\sqrt[3]{2} }{7-2} {[/tex]
=[tex]-\frac{\sqrt[3]{2} }{5}+\frac{\sqrt[3]{7} }{5}[/tex]
=0.1306
≈ 0.13 (rounding off nearest hundredth)

Out of 60 people surveyed 42 respond yes to the server question what is the relative frequency of yes responses
Answer: 7/10
Step-by-step explanation:
Number of people surveyed = 60
Number of people who responded Yes = 42
The relative frequency will be the fraction of those who responded yes divided by the total people surveyed. This will be:
= 42/60
= 7/10.
The relative frequency is 7/10.

There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what sea is in simplest radical form
Answer:
C = 18
Step-by-step explanation:
There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form
Solution:
A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.
The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).
A right angled triangle is a triangle with one angle equals to 90 degrees.
Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:
sin30 = 9 / C
0.5 = 9 / C
C = 9/0.5
C = 18

x=10.4
Step-by-step explanation:
well 20*5=what? 20*5=100 but then x would have to be a decimal. not a tough one though.
10*x (x being 10) 10*10 would be 100 but then you would have to subtract 4 from it. it's easy. 10 *10.4 is 104.
x would = 10.4 to get this result

The diameter of a circle is 46 yards. What is the circle's circumference? d=46 yd Use 3.14 for n.
Answer:
144.44 yards
Step-by-step explanation:
The formula to find circumference is: C = π · d
Since we already have most of the factors figured out, we just replace them with what we have.
C = 3.14 · 46 yrds
144.44 = 3.14 · 46

Step-by-step explanation:
Since this is a right triangle, we can use trig functions
Cos theta = adj side/ hypotenuse
cos A = 24/51
Step-by-step explanation:
We know that cosA=Base/hypontenuse
➡CosA=24/51
Reason :-This is a right angle triangle
Cos theta=Base/hypontenuse

el punto (4, -3) esta sobre el lado terminal del angulo 0 en posicion normal. hallar el valor de las seis razones trigonometricas de ese angulo
Answer:
Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:
Tan(θ) = y/x
Cos(θ) = x/(√(x^2 + y^2))
Sin(θ) = y/(√(x^2 + y^2))
Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:
Ctg(θ) = x/y
Sec(θ) = √(x^2 + y^2)/x
Csc(θ) = √(x^2 + y^2)/y
En este caso tenemos el punto (4, -3), es decir:
x = 4
y = -3
Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:
Tan(θ) = -3/4
Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5
Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5
Ctg(θ) = 4/(-3) = -4/3
Sec(θ) = √(4^2 + (-3)^2)/4 = 5/4
Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3
Solve for x. (Only enter the numerical value.)

Answer:
[tex](x - \frac{\sqrt{209} - 1}{8} )(x - \frac{-1 - \sqrt{209} }{8} )[/tex]
Step-by-step explanation:
FACTS TO KNOW BEFORE SOLVING :-
Quadratic Formula :-
Lets say , there's an equation ax² + bx + c.
[tex]=> x = \frac{-b + \sqrt{b^2 - 4ac} }{2a} \: or \: \frac{-b - \sqrt{b^2 - 4ac} }{2a}[/tex]
SOLUTION :-
According to the question ,
a (Coefficient of x²) = 4b (Coefficient of x) = 1c (constant) = -13By using quadratic formula ,
[tex]x = \frac{-1 + \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4} \: or \: \frac{-1 - \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4}[/tex]
[tex]=> x = \frac{-1 + \sqrt{209} }{8} \: or \: \frac{-1 - \sqrt{209} }{8}[/tex]
[tex]=> (x - \frac{\sqrt{209} - 1}{8} ) \: and \: (x - \frac{-1 - \sqrt{209} }{8} )[/tex] are the factors of 4x² + x - 13.
