Answer:
non-linear because there is not a constant rate of change
Step-by-step explanation:
x y
175 213
167 219
145 179
86 98
175-167=8
167-8=159
Answer:
9 + x
Step-by-step explanation:
The area of a rectangle is length times width.
A = lw
We know the area is 81 - x^2 and the width is 9 - x, so plug them in.
81 - x^2 = 9-x * w
81 - x^2 is a difference of squares in the form a^2 - b^2 = (a-b)(a+b), so we know the width must be 9 + x.
Test it to be sure:
(9 + x)(9 - x)
81 + 9x - 9x -x^2 = 81 - x^2
It works!
Answer:
16 is Potential energy and 411.6 Joules, 17 is Kinetic energy 896,000
Step-by-step explanation:
PE=mgh
2 kg(9.8m/sec^2) 21m= 411.6J
KE=1/2mv^2= 1/2(1120kg)(40m/s)^2= 896,000J
Answer:
a=23.5 and b=17.0
Step-by-step explanation:
a) Sin(54)=a/29
29Sin(54)=a
a=23.5
b) Cos(54)=b/29
29Cos(54)=b
b=17.0
The equivalent expression of 25 - 64 are "a), b) and c)"
The given expression is:
25 - 64
To find, the equivalent expressions are:
a) 25 + 40x - 40x - 64
= 25 - 64, is the equivalent expression.
b) 25 + 13x - 13x - 64
= 25 - 64, is the equivalent expression.
c) (5 + 8)(5 - 8)
Using the algebraic identity,
(a + b)(a - b) =
=
= 25 - 64, is the equivalent expression.
d) ( + 13)( - 13)
Using the algebraic identity,
(a + b)(a - b) =
=
= - 169, is not a equivalent expression.
e)
Using the algebraic identity,
, is not a equivalent expression.
∴ The equivalent expression of 25 - 64 are "a), b) and c)".
