Answer:
I think it is 16.
Step-by-step explanation:
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.
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

How are slope and speed related?
Answer:
you will get speed on a slope and you will get speed with speed (:
Step-by-step explanation:
Answer:
The joint dependence of locomotive power on speed and slope is crucial in the non-stationary conditions where the skier passes high and low points along the track where both speed and slope change rapidly.
Step-by-step explanation:
Hope this helps you and also when your going down a slope there is movement which in this case you will pick up speed. If your trying to go up a slope your not going to move as fast rather slow.

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.
A) y = −0.5x − 5.5
B) y = −0.5x + 5.5
C) y = 2x + 13
D) y = 2x − 13
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. (:

Answer:
-7/2
Step-by-step explanation:
Use two points.
(6, -21) and (12, -42)
slope = (y2 - y1)/(x2 - x1)
slope = (-42 - (-21))/(12 - 6)
slope = -21/6
slope = -7/2
If the vertices of APQR are P(0,0), Q (2,0) and R(1,3),
classify the triangle.
Answer:
ΔPQR is a isosceles triangle
Step-by-step explanation:
P (0,0) Q (2,0) R (1,3)
PR² = (3-0)² + (1-0)² = 10
RQ² = (3-0)² + (1-2)² = 10
PR = RQ
ΔPQR is a isosceles triangle

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