Answer:
x = 24
Step-by-step explanation:
Answer:
d) 16x² -56x +49
Step-by-step explanation:
The square of a binomial difference will have the form ...
(ax -b)² = a²x² -2abx +b²
__
The sign of the linear term will be negative, which eliminates choices A and C.
The linear term will be double the product of the roots of the other two terms.
In choice B, the linear term has a factor of 5 that appears nowhere else, so that cannot be a perfect square.
Choice D factors as ...
16x² -56x +49 = (4x -7)² . . . . the square of a difference
L=length. w=width
l=5w
area=5ww=245
5w²=245
w²=49
w=7
l=35
that's one big bleeding table!
Split up each force into horizontal and vertical components.
• 300 N at N30°E :
(300 N) (cos(30°) i + sin(30°) j)
• 400 N at N60°E :
(400 N) (cos(60°) i + sin(60°) j)
• 500 N at N80°E :
(500 N) (cos(80°) i + sin(80°) j)
The resultant force is the sum of these forces,
∑ F = (300 cos(30°) + 400 cos(60°) + 500 cos(80°)) i
… … … + (300 sin(30°) + 400 sin(60°) + 500 sin(80°)) j N
∑ F ≈ (546.632 i + 988.814 j) N
so ∑ F has a magnitude of approximately 1129.85 N and points in the direction of approximately N61.0655°E.
The equation for the given table is y = x-1.
<u>Step-by-step explanation:</u>
Plot the points in the graph.
The formula for finding slope,.
rise = and run =.
Here let us take two points (0,-1) and (1,0).
rise=0-(-1). and run =1-0.
rise= 1 and run 1.
m= 1.
∴ y=x+c.
From the data given the y is one less than x.
∴ y= x-1.
