The amount of ways would be :
9! / (9-3) !
= 9 ! / 6 !
= 9 x 8 x 7
= 504
The answer is option B,
hope this helps
<h3>Answer:</h3><h3>f(x)=5x^(4)+3x^(2)+6x^(-1)-3 =20x^3+6x-6/x2</h3><h3>f(x)=(7)/(8)x^(3)+2x^(5)-6x+17 = f=16x5+7x3−48x+136/8x</h3><h3>f(x)=5\sqrt(3+4x)= \frac{10}{\sqrt{3+4x}}</h3><h3>f(x)=(1)/(x^(2))+(1)/(x)-12x^(2)= -\frac{2}{x^3}-\frac{1}{x^2}-24x</h3><h3>1.yes,2.yes,3.no,4.yes hope this helps</h3>
Answer:
3.14 x 3.5 - 5 x 20
Step-by-step explanation:
The radius is like circumference just multiply the base number by the pi to get the answer.
Multiply the average by the number of exams to find total points:
8 x 55 = 440
9 x 60 = 540
The score of the 9th exam is the difference between the two totals:
540 - 440 = 100
They scored a 100
The angle of elevation from the end of the shadow to the top of the man's head will be 34.077°.
<h3>What is a right-angle triangle?</h3>
It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
A man who is 5feet 9inches tall casts a shadow of 8feet 6inches.
Assuming that the man is perpendicular to the ground.
5 ft 9 in = 69 in
8 ft 6 in = 102 in
Then the angle of elevation from the end of the shadow to the top of the man's head will be
tan θ = 69/102
θ = tan ⁻¹ (0.676)
θ = 34.077°.
