Hello!</h2>
The answer is:
The correct option is
a) 
<h2>
Why?</h2>
Since a right triangle is formed, we can calculate the resultant force using the Pythagorean Theorem which states that:
Where,
c, is the hypothenuse.
a, is one triangle leg.
b, is the other triangle leg.
So, we are given the information:
So, calculating the resultant force (hypothenuse), we have:
Hence, the expression that would find the result velocity is:
a) [tex]Resultant=\sqrt{22^{2} +4^{2} }[/tex]
Have a nice day!
Hello,
P(x)=x^4-6x²+2=(x-a)(x-b)(x-c)(x-d)
=x^4-(a+b+c+d)x^3+(ab+ac+ad+bc+bd+cd)x^2-(abc+abd+acd+bcd)x+abcd
==>
ab+ac+ad+bc+bd+cd=-6
abc+abd+acd+bcd=0
abcd=2
a+b+c+d=0 ==>(a+b+c+d)²=0=a²+b²+c²+d²+2(ab+ac+ac+bc+bd+cd)
==>a²+b²+c²+d²=0-2*(-6)=12
if a is a root P(a)=0==>a^4-6a²+2=0
if b is a root P(b)=0==>b^4-6b²+2=0
if c is a root P(a)=0==>c^4-6c²+2=0
if d is a root P(a)=0==>d^4-6d²+2=0
==>a^4+b^4+c^4+d^4-6(a²+b²+c²+d²)+4*2=0
==>a^4+b^4+c^4+d^4=-8+6*12=64
Answer:
The Area of the bicycle wheel=380.182 square inch
Step-by-step explanation:
The formula for calculating the area of a wheel is given by;
A=(πd²)/4
A=Area of the wheel to be calculated
Where π (pie)=3.142,
The wheel size is usually denoted by its diameter (d)
d=diameter of the wheel=22 inches
with the values of π and d given, we can plug them in the formula for calculating Area to determine the area of the bicycle wheel
Substituting the values for π and d in the formula;
A=(πd²)/4=(3.142×22²)/4=380.182 in²
The Area of the bicycle wheel=380.182 in²
Answer:
D
Step-by-step explanation:
Δ CBA and Δ SAR are similar
Thus the ratios of corresponding sides are equal, that is
= 
, substituting values gives
= 
( cross- multiply )
10x = 20 ( divide both sides by 10 )
x = 2
Thus
AS = x = 2
