Intuitively we're being asked how many points on the radius 1 circle centered at (4,1) are three units from the y axis. The answer is pretty obviously
Answer: One point
We'll work it out the usual way.
Let's give coordinates (x,y) to a point 3 units from the y axis and 1 unit from (4,1).
The x coordinate tells us how far we are from the y axis. 3 units from the y axis means
|x| = 3
x = ±3
One unit from (4,1) means
(x - 4)² + (y - 1)² = 1²
Let's try x=-3
(-7)² + (y - 1)² = 1
(y - 1)² = -48
No solution there
Let's try x=3
(3 - 4)² + (y - 1)² = 1
(-1)² + (y - 1)² = 1
(y - 1)² = 0
y - 1 = 0
y = 1
So (3,1) is the only point 3 units from the y axis and 1 unit from (4,1).
That verifies our answer above.

Answer:
The 16 cases will fit the box as shown.
Step-by-step explanation:
One disk case has the dimensions 14.2 cm by 19.3 cm, with thickness 1.6 cm.
Temporarily ignoring the 14.2 cm and 19.3 cm measurements, we multiply this 1.6 cm thickness by 16, obtaining a total thickness for the stack of cases of 25.6 cm.
1) The 16 cases, arranged as shown, and measuring 25.6 cm from left to right in this diagram, will fit within the 26 cm horizontal distance shown.
2) The horizontal length of each case is 14.2 cm. Stacked as shown, the 16 cases will fit within the 15 cm depth of the box.
3) The vertical measurement of each case is 19.3 cm. The 20 cm vertical measurement of the box can accommodate this 19.3 height within 20 cm.
All indications are that the 16 cases will fit comfortably inside the box.
Answer:
16 discs capacity of the cuboid.
Step-by-step explanation:.
for simplicity...
i would just divide 26cm to 1.6cm = 16 .25
therefore, 16 discs capacity of the cuboid.

Answer:
x=7.13 centimeters
Step-by-step explanation:
Remember!!! Trig Functions: Sinθ=Opposite/Hypotenuse, Cosθ=Adjacent/Hypotenuse, tanθ=Opposite/Adjacent (An easy way to remember is SOH CAH TOA)
For this particular problem you need to find the opposite side and the hypotenuse is given and so is the angle. So we can plug into Sinθ=Opposite/Hypotenuse in our calculator:
Sin(63°)=x/8
8(Sin(63°))=x
x=7.13
Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

Answer:
255.7cm^2 to 1 dp
Step-by-step explanation:
Area of a full circle is: pi R^2
= pi 10^2
= 100 x pi
= 314.159265 cm^2
We then divide by 314.159265/ 360 = 0.872664625 cm^2
And multiply by 293 x 0.872664625 = 255.690735 cm^2
= 255.7cm^2

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

1/4 divided by 1 1/8
pls help ill give big brain
Answer:
2/9
Step-by-step explanation:
1/4 divided by 1 1/8.
First rewrite 1 1/8 as an improper fraction.
You now have 1/4 divided by 9/8.
When dividing by a fraction you multiply by the reciprocal.
You now have 1/4 * 8/9.
Now Multiply the numerators across and the denominators across to get 8/36.
Simplify the fraction. 2/9

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
The price was $250. Now its 100 find the percentage change
Answer:
Step-by-step explanation:
The formula for percent change is
\(\frac{original-new}{original}*100\)
Therefore,
\(\frac{250-100}{250}*100=60\)%
Answer: 60%
Step-by-step explanation:250 - 100 = 150
150/250 = 60/100 = 60%
