Which one of these numbers is a perfect square? 21, 15, 6, 16, 27

Answers

Answer 1

Answer:

I think it is 16.

Step-by-step explanation:

Answer 2

Answer:

16

Step-by-step explanation:

Perfect squares are numbers that can be written as the product of a different number and itself: k * k = k^2.

Looking at the numbers:

21: can be written as 3 * 7, but not in the form k^2

15: can be written as 3 * 5, but not in the form k^2

6: can be written as 2 * 3, but not in the form k^2

16: can be written as 4 * 4, which is in the form of k^2

27: can be written as 3 * 9, but not in the form k^2

Thus, the answer is 16.

Hope this helps!

th term of a seq uence is n(n-4) /n+3 Work out the sum of the 1st and 6th terms.

Answers

Answer:

7/12

Step-by-step explanation:

The nth term Tₙ = n(n-4) /n+3.

The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4

The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3

So,  the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3

= (-9 + 16)/12

= 7/12

Write an equation of a line perpendicular to line CD below in slope-intercept form that passes through the point (−1, 6). Line CD is shown. C is at 1, 1. D is at 3, 5.

B) y = −0.5x + 5.5
C) y = 2x + 13
D) y = 2x − 13

Answers

Answer:

i believe it's b:))

Step-by-step explanation:

Answer:

I don't know but I am pretty sure it can't be C or D.

Step-by-step explanation:

The slope of line CD simplifies to 2, so for the perpendicular line to be perpendicular, it must be an opposite reciprocal, meaning -1/2 or -0.5. I don't know what B equals though, whether it is positive or negative.

Hope that helps. (:

The zeros of a polynomial function are 1/2, -4 and -1. What are the factors?

Answers

Answer:

The factors are;

(x + 4) , (x + 1) and (2x-1)

Step-by-step explanation:

Given the zeros, we want to get the factors

To get the zeros, we simply equate the factors to zero and solve for x

so for x = 1/2

we can have x - 1/2 = 0

multiply through by 2

= 2x - 1

for x = -4

x + 4

for x = -1

x + 1

So the factors are;

(x + 1) , (x + 4) and (2x-1)
