Answer: [tex]y^\frac{1}{8}[/tex]
Step-by-step explanation:
Ok so when taking roots the number in the little corner at the left of the radical sign (if there is one) is the root you take. It could be the 4th root, 6th root, or the x root. You don't have to use the radical sign though, you can use an exponent to write it. All you have to do is take the reciprocal of the number to find what to write for the exponent. So for those examples it would be [tex]\frac{1}{4}, \frac{1}{6} ,\frac{1}{x}[/tex]. The number in the top left of the radical sign is 8 so the answer would be [tex]y^\frac{1}{8}[/tex]

A telephone pole has a wire attached to its top that is anchored to the ground. The distance from the bottom of the pole to the anchor point is 49 feet less than the height of the pole. If the wire is to be 14 feet longer than the height of the pole, what is the height of the pole?
9514 1404 393
Answer:
105 ft
Step-by-step explanation:
Let x represent the height of the pole. Then (x -49) is the distance from the pole to the anchor point, and (x+14) is the length of the wire from the top of the pole to the anchor point.
The Pythagorean theorem gives us the relation ...
(x +14)² = x² +(x -49)²
x² +28x +196 = x² +x² -98x +2401 . . . . eliminate parentheses
x² -126x +2205 = 0 . . . . . . . . put in standard form
x² -126x +3969 -1764 = 0 . . . . "complete the square)
(x -63) = ±√1764 . . . . . . add 1764, take the square root
x = 63 +42 = 105 . . . . . . highest value root. The pole must be higher than 49 feet
The height of the pole is 105 feet.

A company produces optical-fiber cable with a mean of 0.6 flaws per 100 feet. What is the probability that there will be exactly 4 flaws in 1000 feet of cable
Answer:
[tex]P(X = 4) =0.133[/tex]
Step-by-step explanation:
From the question we are told that:
Mean [tex]\x=0.6/100[/tex]
Flaws [tex]f=4[/tex]
Distance [tex]d_2=1000ft[/tex]
Generally the equation for Poisson mean lambda over 1000 is mathematically given by
[tex]\lambda=0.6*1000/100[/tex]
[tex]\lambda = 6[/tex]
Therefore
[tex]P(X = 4) = {e^-\lambda * \lambda^{\=x}} {{\=x}!}[/tex]
[tex]P(X = 4) =\frac{ e^{-6} * 6^4}{ 4!}[/tex]
[tex]P(X = 4) =0.133[/tex]

Work Shown:
[tex](f - g)(x) = f(x) - g(x)\\\\(f - g)(x) = (2x+1) - (x^2-7)\\\\(f - g)(x) = 2x+1 - x^2+7\\\\(f - g)(x) = -x^2+2x+(1+7)\\\\(f - g)(x) = -x^2+2x+8\\\\[/tex]
which shows the answer is choice A.
Side note: be sure to distribute the negative to every term inside the second set of parenthesis. So you wouldn't say -(x^2-7) = -x^2-7. If you did this error, then you'd get to the wrong answer choice C.

Find the volume of the figure. Round to the nearest tenth if necessary.
Answer:
Volume = 204 m³
Step-by-step explanation:
The figure is a triangular prism
Volume of the triangular prism = ½ × a × c × h
Where,
a = 8 m
c = 5.1 m
h = 10 m
Plug in the known values and solve
Volume = ½ × 8 × 5.1 × 10
Volume = 4 × 5.1 × 10
Volume = 204 m³

Water is leaking out of an inverted conical tank at a rate of13400cubic centimeters per min at the same time that water is being pumped into the tank at a constant rate. The tank has height8meters and the diameter at the top is6meters. If the water level is rising at a rate of24centimeters per minute when the height of the water is5meters, find the rate at which water is being pumped into the tank in cubic centimeters per minute.
9514 1404 393
Answer:
2,664,118.8 cm³/min
Step-by-step explanation:
The diameter at the water level of 5 m is (5/8)(6 m) = 3.75 m, so the area of the water surface is ...
A = (π/4)d² = (π/4)(3.75 m)² ≈ 11.044662 m²
When rising at the rate of 24 cm/min, the volume is increasing at the rate ...
(110,446.62 cm²)(24 cm/min = 2,650718.8 cm³/min
The input volume must be sufficient to accommodate this increase as well as the leakage. Then the input volume is ...
2,650718.8 cm³/min + 13,400 cm³/min = 2,664,118.8 cm³/min

Which system of linear inequalities has the point (3, -2) in its solution set?
Answer:
None of the given system of linear inequalities
Step-by-step explanation:
Given
[tex](x,y) =(3,-2)[/tex]
Required
The line inequalities with the above solution
The first set of linear inequalities, we have:
[tex]y < -3[/tex]
[tex]y \ge \frac{2}{3}x - 4[/tex]
[tex]y < -3[/tex] implies that the values of y is -4,-5.....
While [tex](x,y) =(3,-2)[/tex] implies that y = -2
Hence, the first set is wrong
The second set of linear inequalities, we have:
[tex]y > - 2[/tex]
[tex]y \ge \frac{2}{3}x - 4[/tex]
[tex]y > - 2[/tex] implies that the values of y is -1,0.....
While [tex](x,y) =(3,-2)[/tex] implies that y = -2
Hence, the second set is wrong
The system of linear inequalities having the point (3, -2) in its solution set is y > -3; y ≥ 2/3x - 4.
What are systems of linear inequalities?A system of linear inequalities is known to be a composition of linear inequalities that can be found in the same variables.
The graph that is showing y > -3; y ≥ 2/3x - 4
-2 > -3 is true
y ≥ 2/3x - 4
-2 ≥ -2 is true
Therefore, y > -3; y ≥ 2/3x - 4 has the point (3, -2) in its solution set.

The perimeter of a collage basketball court is 96 meters and the length is 14 meters more than the width. What are the dimensions? HELP MEEEEE
Answer:
width = 17 m ; length = 31 m
Step-by-step explanation:
w = width
l = length
perimeter of a rectangle = (length + width) * 2
l = 14 + w
(14 + w + w) * 2 = 96
(14 + 2w) * 2 = 96
28 + 4w = 96
4w = 68
w = 17 m
l = 14 + 17 = 31 m

B. The graph of f(x) is shifted 11 units to the right.
C. The graph of f(x) is shifted 11 units up.
D. The graph of f(x) is shifted 11 units down.
Answer:
C. The graph of f(x) is shifted 11 units up.
Step-by-step explanation:
Given
[tex]g(x) = f(x) + 11[/tex]
Required
Interpret g(x)
When a function is shifted up in b units, the rule is:
[tex](x,y) \to (x,y+b)[/tex]
Replace b with 11
[tex](x,y) \to (x,y+11)[/tex]
Replace y with f(x)
[tex](x,f(x)) \to (x,f(x)+11)[/tex]
So, we have:
[tex]g(x) = f(x) + 11[/tex]
Hence; f(x) is shifted 11 units up.

on monday, sammy the storekeeper decided the increase the price of avocados by 20%. on tuesday he increases this price by another 25%. what percent of the original avocados after both increases? on Wednesday, sammy decides to return the avocados to their original price. by what percent must he decrease the tuesday price?
Answer:
I think 55%
Step-by-step explanation:
Answer:
Increases = 50%On Wednesday, sammy must decrease 50% to return to original priceStep-by-step explanation:
price on monday go to: 100% + 20% = 120% = 1,2 x first price
price on tuesday go to: 125% of 120% = 1,25 x 1,2 = 1,5 x first price
Increases = 50%
on Wednesday, sammy must decrease 50% (of price after second increases) to return to original price
For example for understanding:
If original price is $100
firs increase: new price: $100 + $20 = $120
second increase: new new price: $120 + $30 = $150
final price - original price = $150 - $100 = $50
And icreases/original = $50/$100 =0,5 = 50%
For return to orignial price, sammy must have to reduce 50% the price of avocados in wednesday
