Answer:

5a^4 b^2 + 32a^4 + 9b^2

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((32•(a^4))+(9•(b^2)))+(5a^4•b^2)

Step  2  :

Equation at the end of step  2  :

 ((32 • (a^4)) +  32b^2) +  5a^4 b^2

Step  3  :

Equation at the end of step  3  :

 (2^5a^4 +  3^2 b^2) +  5a^4 b^2

Step  4  :

Trying to factor a multi variable polynomial :

A student is instructed to square a binomial and gets the results show
otez555 [7]

The correct option about squaring the binomial is that B. The student is wrong. There is a missing term.

<h3>How to use binomial theorem?</h3>

We want to square a binomial and using pascal's triangle in binomial theorem, we know that; (x + a)² will follow the pattern;

1x²a⁰ + 2a¹x¹ + 1x⁰a²

Thus, we can say that the expression (x + 3)² will give us;

x² + 2(3x) + 9a²

= x² + 6x + a²

Thus, we can say that the correct option about squaring the binomial is that B. The student is wrong. There is a missing term.

Complete Question is;

A student is instructed to square a binomial, and gets the result shown. Choose the correct description of the student's work.  (x + 3)² = x² + 9 Choose the correct answer below.

A. The student is wrong. You cannot square a binomial, only monomials.

B. The student is wrong. There is a missing term.

C. The student is correct. Each given term is squared.

D. The student is wrong. The student should add the threes instead of multiplying them.

2th bounce- 80
5th Bounce- (-)200
9th Bounce- (-)560

Every time the ball bounces it loses 40cm because on the first bounce 160cm-120cm=40cm
And the score goes down by 40 every time and since we go into the negatives the negatives sometimes add on top of each other

Use forward or backward substitute to conjecture a closed formula which describes the nth term of the sequence an = an-1 – n, wh
WINSTONCH [101]
The closed formula for  <span>an = an-1 – n will be found using the formula for arithmetic sequence given by:
an=a+d(n-1)
where
a=first term
d=common difference
n=number of terms
From the formula given:
a=4
d=n
thus the formula will be:
an=a+n(n-1)
an=4+n(n-1)

a chord subtend an angle of 72⁰ at the center of a circle with radius 24.5m. calculate the perimeter of the minor segment​
andre [41]

The perimeter of the minor segment is 77. 4m

<h3>How to determine the perimeter</h3>

The formula for determining the perimeter of the minor segment is given as;

Perimeter = θ/360 × 2πr + 2r sin θ/2

where;

  • radius = 24. 5m
  • θ = 72

Substitute into the formula;

Perimeter = (72/360 × 2 × 3. 142 × 24. 5) +( 2 × 24. 5 × sin 72)

Perimeter = 30. 79 + 46. 60

Perimeter = 77. 4 m

Thus, the perimeter of the minor segment is 77. 4m
