Answer:
Before you write the answer to your question, make sure the question is asking for the actual value of pi or 3.14.
If the question was asking for the question to be completed with the ACTUAL VALUE of pi, then your answer is ----> 4.37
If the question was asking for the question to be completed with the rounded of pi (3.14), then your answer is ----> 4.38
It's a subtle difference, but remember, there is no such thing as close in math, it's either right or wrong.
Step-by-step explanation:
Given: Circle's Area, 60.12
As the value of pi was not directly stated, I will divide the answer into 2 portions, portion one with the answer with the actual infinite value of pi, and one where I will describe how to do it with 3.14 as pi.
Explanation with 3.14:
First thing first, know the formula for calculating the area of a circle:
[tex]A = \pi r^2[/tex]
[tex]A[/tex] stands for Area, and [tex]r[/tex] stands for Radius
Now, plug in the given values:
[tex]60.12 = \pi r^2[/tex]
Next, replace 3.14 for pi:
[tex]60.12 = (3.14)r^2[/tex]
Then, divide both sides by 3.14 ,which gives us:
[tex]19.15 = r^2[/tex]
Please note: 19.15 is rounded
Anyway, to isolate [tex]r[/tex], we take the square root of both sides:
[tex]\sqrt{19.15} = \sqrt{x^2}[/tex]
The square root and square on the right side of the equation cancel out, and we are left with:
[tex]4.38 = r[/tex]
Please note that 4.38 was rounded

у
х
oo
Answer:
x = 3.255 cm
Step-by-step explanation:
Given:
⇒ y = 10cm
⇒ θ = 19
To find:
⇒ Value of "n"
Solution
⇒ By Pythagoras theorem
⇒ Δ Sin θ = n/y
⇒ sin 19° = n/10
⇒ 0.3255 = n/10
⇒ n = 0.3255 × 10
⇒ n = 3.255 cm
Hence, the answer is = n = 3.255 cm.

A cylinder has a circumference of 16pi inches and a height of 20 inches. what is the surface area of a cylinder in square inches?
Answer:
1407.43
Step-by-step explanation:
The eqaution for surface area of a cylinder is 2πr+2π[tex]r^{2}[/tex]'
but you already got the circumference so you work backwards
16pi/pi=16
16/2=8
r=8
h=20
So you plug it into the eqaution
2π8*20+2π8^2=1407.43
If f(x)=X²-3, what is the value of f(-3)?
__________________________________________________________
Hello! In this question, we are trying to solve the expression with a given value.
__________________________________________________________
Explanation:
In this question, we were given our f(x) equation: f(x) = x² - 3
We were also given the value of our variable "x": -3
To solve the expression, we would plug in our "x" value, -3, into the "x" variables in our expression and solve.
Solve:
f(x) = x² - 3
f(-3) = (-3)² - 3
= 9 - 3
= 6
Therefore, the value of f(-3) is 6.
__________________________________________________________
Answer:
f(-3) = 6
__________________________________________________________
To solve this problem, you will substitute an existing value into a function in order to find the y-coordinate at that x-coordinate.
SubstituteGiven the function f(x) = x² - 3, evaluate the function at f(-3) by substituting in x = -3:
[tex]f(-3) = -3^2-3[/tex]
Use Order of OperationsUse BPEMDAS, which stands for:
Brackets
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
First, evaluate -3².
[tex]-3\times-3=9[/tex]
Then, evaluate the rest of the expression by subtracting 3 from 9:
[tex]9 - 3 = \boxed{6}[/tex]
The final answer is f(-3) = 6.
Find the circumference of a circle whose radius is 16. Leave your answer in terms of π.
Answer:

Using the equation, y=5x²−17x −12, determine the roots.
A) (-4, 0) and (0.6, 0)
b) (-4, 0) and (-0.6, 0)
c) (4, 0) and (-0.6, 0)
d) (4, 0) and (0.6, 0)
Answer:
c
Step-by-step explanation:
y = 5x² - 17x - 12
to find the roots let y = 0 , that is
5x² - 17x - 12 = 0
Factorising the quadratic
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 5 × - 12 = - 60 and sum = - 17
the factors are - 20 and + 3
use these factors to split the x- term
5x² - 20x + 3x - 12 = 0 ( factor first/second and third/fourth terms )
5x(x - 4) + 3(x - 4) = 0 ← factor out (x - 4) from each term
(x - 4)(5x + 3) = 0
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - [tex]\frac{3}{5}[/tex] = - 0.6
roots are (4, 0 ) and (- 0.6, 0 )

Answer:
-x^4-5x^3+2x²+ 10x = (x+5)(2x-x³)
Step by Step explanation
Naming the coefficient of x² as "a" and the independent temine of the first parenthesis as "b", we got:
-x^4-5x^3+ ax^2 +10x=(x+b)(2x-x^3)
- x⁴-5x^3+ ax^2 +10x = 2x²- x⁴+2bx-bx³
-5x^3+ ax^2 +10x = -bx³+2x²+2bx
( Matching the exponents)
For x: 2b= 10; b=10/2.
b=5
For x²: a=2
For x³: -b=-5
