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

Answer:
well I think it is so because it has to do with affecting the positive sign just think of it using normal circumstances
Step-by-step explanation:
formally, there is only one alternative : if not negative, it would be a positive number.
and that would mean
2× -4/5 = x (= a positive number)
2× -4 = 5x (= still a positive number)
-4 = 5x/2 (= still a positive number)
and -4 is definitely not a positive number.
so, it is proven, 2× -4/5 cannot be a positive number, and therefore has to be a negative number.

Answer:
The length of the wing is 480 centimeters
Step-by-step explanation:
2 cm on the drawing is 192 cm on the acutal wing
2 = 192
divide both sides by 2
1 = 96
since the drawing has a length of five cm, multiply both sides by 5
5 = 480
therefore, 5 cm on the drawing is equal to 480 cm on the actual wing

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.
