Kyler noticed that there were seven microscopic sea creatures lined up end to end. If each creature was 3.9 x 10 cm long, how long was the chain?
If the planet Neptune is 2.794 x 10 miles from the sun and the planet Earth is 9.3 x 10' miles from the sun, how many times farther away from the sun is Neptune than Earth?
Answer: 273 cm, 300
Step-by-step explanation:
Given
The length of each sea creature is [tex]3.9\times 10\ cm[/tex]
for 7 microscopic creature, it is
[tex]\Rightarrow 7\times 3.9\times 10\\\Rightarrow 273\ cm[/tex]
The distance of Neptune from the sun is [tex]2.794\times 10^9\ \text{miles}[/tex]
and the earth is [tex]9.3\times 10^7\ \text{miles}[/tex] from the sun
Comparison of neptune and earth distance
[tex]=\dfrac{2.794\times 10^9}{9.3\times 10^7}\\\\=0.300\times 10^2\\=300.4[/tex]
Neptune is 300 times farher away form the sun than earth

[tex]\displaystyle f'(x)=\lim_{h\to0}\frac{\frac{2-(x+h)}{2+(x+h)}-\frac{2-x}{2+x}}h[/tex]
[tex]\displaystyle f'(x)=\lim_{h\to0}\frac{\frac{(2-x-h)(2+x)-(2-x)(2+x+h)}{(2+x+h)(2+x)}}h[/tex]
[tex]\displaystyle f'(x)=\lim_{h\to0}\frac{-4h}{h(2+x+h)(2+x)}[/tex]
[tex]\displaystyle f'(x)=-4\lim_{h\to0}\frac1{(2+x+h)(2+x)}=\boxed{-\frac4{(2+x)^2}}[/tex]

Answer:
x = 6/√3
y = 3/√3
Step-by-step explanation:
For a triangle rectangle with a known angle θ, we have the relations:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Cos(θ) = (adjacent cathetus)/(hypotenuse)
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
For this triangle, we know an angle:
θ = 60°
And the opposite cathetus measures 3 units.
The adjacent cathetus is y.
The hypotenuse is x.
To find the value of x, we can use the Sin equation:
Sin(60°) = 3/x
x = 3/sin(60°) = 3.46 = 3*2/√3 = 6/√3
And we can use the Tan relation to find the value of y.
Tan(60°) = 3/y
y = 3/Tan(60°) = 1.73 = 3/√3
For x he didn't divide by √3, while for y he multiplied by √3 instead of dividing by √3.

a) what is the length of the ramp?
b) Find measure of the angle incline.
Answer:
a) 13 feet
b) 22.6º
Step-by-step explanation:
c² = 12² + 5²
c² = 144 + 25
c² = 169
Take the square root of both sides
c = 13 Feet

Identify the translation of the figure with the vertices P(2,3), Q(−1,0), and R(1,−2), along the vector ⟨4,0⟩.

9514 1404 393
Answer:
B. P ′(6, 3), Q ′(3, 0), R ′(5, −2)
Step-by-step explanation:
The translation vector tells you that 4 is added to each x-coordinate.
(x, y) ⇒ (x, y) +(4, 0) = (x +4, y)
Then ...
P(2, 3) ⇒ P'(2+4, 3) = P'(6, 3) . . . . . matches B or D
Q(-1, 0) ⇒ Q'(-1+4, 0) = Q'(3, 0) . . . . . matches choice B
Check
R(1, -2) ⇒ R'(1 +4, -2) = R'(5, -2) . . . . . also matches choice B
An elementary school is creating a rectangular garden on the side of the school building. The school has raised money to purchase 1000 feet of fence. In order to maximize the area they are using the building for one side and therefore need to use the fencing for the other three sides of the garden. Find the dimensions the school should use to maximize the area of the garden.
Answer:
[tex]Length = 500ft[/tex]
[tex]Width = 250ft[/tex]
Step-by-step explanation:
Given
[tex]P = 1000[/tex] --- perimeter
Required
The dimensions that maximize the area
Let
[tex]L \to Length[/tex]
[tex]W \to Width[/tex]
Such that:
[tex]P = L + 2W[/tex] ---- Because one side is from the school building
This gives:
[tex]L + 2W = 1000[/tex]
Make L the subject
[tex]L = 1000 - 2W[/tex]
The area is then calculated as:
[tex]A= L * W[/tex]
Substitute: [tex]L = 1000 - 2W[/tex]
[tex]A= (1000 - 2W) * W[/tex]
Open bracket, then set A to 0
[tex]A = 1000W - 2W^2[/tex]
[tex]1000W- 2W^2 = 0[/tex]
Rewrite as:
[tex]-2W^2 + 1000W = 0[/tex]
Assume the form of the above equation is: [tex]aW^2 + bW + c = 0[/tex]
The value of W that maximizes it is:
[tex]W = -\frac{b}{2a}[/tex]
Where
[tex]a = -2[/tex]
[tex]b = 1000[/tex]
[tex]c = 0[/tex]
So:
[tex]W = -\frac{1000}{2*-2}[/tex]
[tex]W = \frac{1000}{2*2}[/tex]
[tex]W = \frac{1000}{4}[/tex]
[tex]W = 250[/tex]
Recall that:
[tex]L = 1000 - 2W[/tex]
[tex]L =1000 - 2 * 250[/tex]
[tex]L =1000 - 500[/tex]
[tex]L = 500[/tex]
So, the dimensions that maximize the area is:
[tex]Length = 500ft[/tex]
[tex]Width = 250ft[/tex]
If you place a 35-foot ladder against the top of a 31-foot building, how many feet will the bottom of the ladder be from the bottom of the building? Round to the nearest tenth of a foot.
Answer:
4ft
Step-by-step explanation:
The bottom of the ladder will be 16.25 feet from the bottom of the building.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
As per the situation, we create a right triangle as shown.
Let x be the distance from the bottom of the building to the bottom of the ladder.
Using Pythagoras's theorem, then, we have:
x² + 31² = 35²
Simplifying this equation, we get:
x² = 35² - 31²
x² = 264
x = 16.25 (rounded to the nearest tenth of a foot).
Therefore, the bottom of the ladder will be 16.25 feet from the bottom of the building.

The area of the rectangle to the nearest square centimeter will be 15 square centimeters. Then the correct option is E.
What is the area of the rectangle?Let W be the rectangle's width and L its length.
The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be
Area of the rectangle = L × W square units
A golden rectangle has a length of 5 cm. Then the width of the rectangle is given as,
W = 5 - 2
W = 3 cm
Then the area of the rectangle will be given as,
A = 5 x 3
A = 15 square centimeters
The area of the rectangle to the nearest square centimeter will be 15 square centimeters. Then the correct option is E.

Since an instant replay system for tennis was introduced a a major tournament, men challenged 1390 referee calls, with the result that 411 of the calls were overturned. Women challenged 753 referee calls, and 213 of the calls were overturned. Use a .05 significance level to test the claim that men and women have equal success in challenging calls.
Required:
a. Test the claim using a hypothesis test.
b. Consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls. What are the null and alternative hypotheses for the hypothesis test?
c. What is the conclusion based on the hypothesis test?
Answer:
H0: μm − μw = 0
against the claim
Ha: μm − μw ≠ 0
Since the calculated value of z= 0.6177 does not lie in the critical region the null hypothesis is accepted that men and women have equal success in challenging calls.
Step-by-step explanation:
1) Let the null and alternate hypothesis be
H0: μm − μw = 0
against the claim
Ha: μm − μw ≠ 0
2) The significance level is set at 0.05
3) The critical region is z > + 1.96 and z< -1.96
4) The test statistic
Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]
Here p1= 411/ 1390= 0.2956 and p2= 213/753=0.2829
pc = 411+ 213/1390+753
pc=624/2143
pc= 0.2912
qc= 1-pc= 1-0.2912=0.7088
5) Calculations
Z= p1-p2/ sqrt [pcqc( 1/n1+ 1/n2)]
z= 0.2956-0.2829/√ 0.2912*0.7088( 1/1390+ 1/753)
z= 0.0127/ √0.2064 (0.00204)
z= 0.0127/0.02056
z= 0.6177
6) Conclusion
Since the calculated value of z= 0.6177 does not lie in the critical region the null hypothesis is accepted that men and women have equal success in challenging calls.

Two boats started to move towards each other from two docks, located 30 miles apart. One boat moved at a speed of 3 miles per hour, the other moved twice as fast. How soon will the boats meet?
Answer:
3.333 hours
Step-by-step explanation:
Given the total distance is 30 miles, and boat 1 travels at 3 mph and boat 2 travels at 6 mph, and the time for both is the same. Distance is speed S times time T so
30 = D(boat 1) + D(boat 2)
30 = (S1 * T) + (S2 * T)
30 = 3T + 6T
30 = 9T
3.333 = T
