Answer:
85 feet
Step-by-step explanation:
P=2L+2W where L is the length and W is the width. If the length is 50 feet longer than the width, we can write the expression L=50+W. Substituting into P=2L+2W we get P=2(50+W)+2W=100+2W+2W=100+4W. Since P=300, we can say 300=100+4W. Subtracting 100 from each side we get 200=4W. Dividing each side by 4 gives 50=W. Substituting this into L=50+W gives L=50+35=85. The length is 85 feet.
neverminding the dots or points on the line, we can see that the line is using a solid stroke, is a solid line, as opposed to a dashed one.
A solid line means, "the borderline is included in the inequality", so that means either ⩾ or ⩽, depending on how you'd write the expression.
so we can say
y ⩽ "some expression in x-terms here"
or we can say
"some expression in x-terms here" ⩾ y
basically the same thing.
the cat is red
and
red is the cat
same thing, depends on how you write it.

Answer:
The launch angle should be adjusted to 30.63°
Step-by-step explanation:
The range of a projectile which is the horizontal distance covered by the projectile can be expressed as;
R =(v^2 sin2θ)/g
Where
R = range
v = initial speed
θ = launch angle
g = acceleration due to gravity
For the case above. When the projectile is launched at angle 13° above the horizontal.
θ1 = 13
R1 = (v^2 sin2θ1)/g
R1 = (v^2 sin26°)/g ....1
For the range to double
R2 = (v^2 sin2θ)/g .....2
R2 = 2R1
Substituting R2 and R1
(v^2 sin2θ)/g = 2 × (v^2 sin26°)/g
Divide both sides by v^2/g
sin2θ = 2sin26
2θ = sininverse(2sin26)
θ = sininverse(2sin26)/2
θ = 30.63°
Answer:
4
Step-by-step explanation:
The integers are
x
x+1
x+2
x+3
x+4
since they are consecutive
The largest is x+4
The smallest is x
Difference is
x+4 -x
4
