Answer:
2√3
Step-by-step explanation:
Since this is a 30-60-90 triangle, we can find s by finding the short leg (bottom), then the hypotenuse (s).
To find the short leg, we can divide the long leg (which is 3mm) by sqrt 3 (also √3, as any of them are fine), and we will have 3/√3. Since we don't want the square root on the bottom, we can multiply √3 on both sides, giving us 3√3/3, which is technically √3 because of simplifying.
Since you have the short leg now, you can find s. By finding s, you can multiply the short leg by 2, which will be √3 * 2 which is 2√3.

The cylinder shown has a lateral surface area of about 400 square inches. Which answer is closest to the measure of the cylinder's radius? Use 3.14 to approximate pi.
Answers
Answer:
r = 1.59inch
the radius of the cylinder is
1.59inch
Step by step Explanation
lateral surface of a cylinder can be calculated using the below formula
Surface Area= 2 πr h
We were given area as 400inch^2 and height as 40inch then substitute we have
400 = 2 ×π × r ×40
400= 2×22/7×40
Then do the calculation, where, π
=22/7
400 = r × 251.2
Make r subject of formula we have
r = 400 / 251.2
r = 1.59inch
Therefore, the radius of the cylinder is
1.59inch

Answer:
E. y = 2/3x
Step-by-step explanation:
You need to make an equation in slope-intercept form.
First, you need to find the slope. You can do this by taking two points and dividing the difference of the y's by the difference of the x's. I will use the first two points, but you can pick whichever points you want and still get the right answer. Also, the values in the left column will be x's, and the values in the right column will be y's.
8 - 2 = 6
12 - 3 = 9
6/9 = 2/3
The slope is 2/3. The only equation with this value is E.

Let $S = 2010 + 2011 + \cdots + 4018$. Compute the residue of $S$, modulo 2009.
Answers
Notice that
2010 ≡ 1 mod 2009
2011 ≡ 2 mod 2009
2012 ≡ 3 mod 2009
...
4017 ≡ 2008 mod 2009
4018 ≡ 0 mod 2009
So really, S is just the sum of the first 2008 positive integers:
[tex]S=\displaystyle\sum_{n=1}^{2008}n=\frac{2008\cdot2009}2[/tex]
where we invoke the formula
[tex]\displaystyle\sum_{i=1}^ni=\frac{n(n+1)}2[/tex]
and so S ≡ 0 mod 2009.

The number of bacteria in a culture is increasing according to the law of exponential growth. There are 105 bacteria in the culture after 2 hours and 325 bacteria after 4 hours. (a) Find the initial population. (Round your answer to the nearest whole number.) bacteria (b) Write an exponential growth model for the bacteria population. Let t represent the time in hours. y
Answers
a) The number of bacteria in the initial population is 34.
b) The exponential growth model is y = 34 * e^(kt)
Given data:
(a) To find the initial population, we can use the exponential growth formula:
y = A * e^(kt)
Where:
y = population at time t
A = initial population
k = growth rate
t = time
Given that there are 105 bacteria after 2 hours, so plug in these values into the formula:
105 = A * e^(k*2)
Similarly, given that there are 325 bacteria after 4 hours:
325 = A * e^(k*4)
We now have a system of equations:
105 = A * e^(2k)
325 = A * e^(4k)
To solve for A, divide the second equation by the first equation:
325/105 = e^(4k)/e^(2k)
Simplifying further:
325/105 = e^(2k)
Taking the natural logarithm of both sides:
ln(325/105) = ln(e^(2k))
ln(325/105) = 2k
Solving for k:
k = 0.56493
Substitute it back into one of the original equations to solve for A. Let's use the first equation:
105 = A * e^(2k)
Substituting k = ln(325/105) / 2:
105 = A * e^(2 * ln(325/105) / 2)
Simplifying:
105 = A * (325/105)
A = 105 * (105/325)
A ≈ 34 (rounded to the nearest whole number)
Hence, the initial population is approximately 34 bacteria.
(b) Now that we have the initial population, A, and the growth rate, k, we can write the exponential growth model for the bacteria population:
y = 34 * e^(kt)
where t represents the time in hours.
Hence, the exponential equations are solved.

An old wheat-grinding wheel in a museum actually works. The sign on the wall says that the wheel has a rotational acceleration of 180 rad/s 2 as its spinning rotational speed increases from zero to 1700 rpm. How long does it take the wheel to attain this rotational speed?
Answers
Answer:
It will take 0.989 second to attain this speed
Step-by-step explanation:
In this question, we want to calculate the time it will take for the wheel of the machine to attain the given rotational speed
We proceed as follows;
From the question, we can identify the following parameters
Rotational acceleration of the wheel is, α = 180 rad/s^2
Initial spinning rotational speed of the wheel is, ω= 0 rpm
1 rpm = (1/60) revolution per second = 2π * (1/60) rad/s
Thus,
initial rotational speed ωi = 0 rad/s
Final spinning rotational speed ωf of the wheel is, = 1700 rpm =178.02 rad/s
Now, from the equations of motion (for rotational motions),
ωf = ωi + αt
where t is the time taken by the wheel to attain its final rotational speed.
178.02= 0 + 180 * t
t = 178.02/180
t = 0.989 second

She has 32 m of fencing so for the lenght remain (32-2x) m of fencing:
y = 32 - 2x
Area of the fencing: A = x•y
A(x) = x•(32 - 2x)
A(x) = -2x² + 32x ← quadratic function
The maximum value of quadratic function occurs at: [tex]x=-\frac b{2a}[/tex]

Given the function [tex]h:x=px-\frac{5}{2}[/tex] and the inverse function [tex]h^{-1} :x=q+2x[/tex], where p and q are constants, find a) the value of p and q c)[tex]h^{-1} h(-3)[/tex]
Answers
Answer:
[tex]p = \frac{1}{2}[/tex]
[tex]q = 5[/tex]
[tex]h^{-1}(h(3)) = 3[/tex]
Step-by-step explanation:
Given
[tex]h(x) = px - \frac{5}{2}[/tex]
[tex]h^{-1}(x) = q + 2x[/tex]
Solving for p and q
Replace h(x) with y in [tex]h(x) = px - \frac{5}{2}[/tex]
[tex]y = px - \frac{5}{2}[/tex]
Swap the position of y and d
[tex]x = py - \frac{5}{2}[/tex]
Make y the subject of formula
[tex]py = x + \frac{5}{2}[/tex]
Divide through by p
[tex]y = \frac{x}{p} + \frac{5}{2p}[/tex]
Now, we've solved for the inverse of h(x);
Replace y with [tex]h^{-1}(x)[/tex]
[tex]h^{-1}(x) = \frac{x}{p} + \frac{5}{2p}[/tex]
Compare this with [tex]h^{-1}(x) = q + 2x[/tex]
We have that
[tex]\frac{x}{p} + \frac{5}{2p} = q + 2x[/tex]
By direct comparison
[tex]\frac{x}{p} = 2x[/tex] --- Equation 1
[tex]\frac{5}{2p} = q[/tex] --- Equation 2
Solving equation 1
[tex]\frac{x}{p} = 2x[/tex]
Divide both sides by x
[tex]\frac{1}{p} = 2[/tex]
Take inverse of both sides
[tex]p = \frac{1}{2}[/tex]
Substitute [tex]p = \frac{1}{2}[/tex] in equation 2
[tex]\frac{5}{2 * \frac{1}{2}} = q[/tex]
[tex]\frac{5}{1} = q[/tex]
[tex]5 = q[/tex]
[tex]q = 5[/tex]
Hence, the values of p and q are:[tex]p = \frac{1}{2}[/tex]; [tex]q = 5[/tex]
Solving for [tex]h^{-1}(h(3))[/tex]
First, we'll solve for h(3) using [tex]h(x) = px - \frac{5}{2}[/tex]
Substitute [tex]p = \frac{1}{2}[/tex]; and [tex]x = 3[/tex]
[tex]h(3) = \frac{1}{2} * 3 - \frac{5}{2}[/tex]
[tex]h(3) = \frac{3}{2} - \frac{5}{2}[/tex]
[tex]h(3) = \frac{3 - 5}{2}[/tex]
[tex]h(3) = \frac{-2}{2}[/tex]
[tex]h(3) = -1[/tex]
So; [tex]h^{-1}(h(3))[/tex] becomes
[tex]h^{-1}(-1)[/tex]
Solving for [tex]h^{-1}(-1)[/tex] using [tex]h^{-1}(x) = q + 2x[/tex]
Substitute [tex]q = 5[/tex] and [tex]x = -1[/tex]
[tex]h^{-1}(x) = q + 2x[/tex] becomes
[tex]h^{-1}(-1) = 5 + 2 * -1[/tex]
[tex]h^{-1}(-1) = 5 - 2[/tex]
[tex]h^{-1}(-1) = 3[/tex]
Hence;
[tex]h^{-1}(h(3)) = 3[/tex]

The length of a rectangular field is twice its breadth. If the area of the rectangular field is 98 sq. M., then what is the perimeter of the field? Also find the approximate length of the diagonal of the field.
Answers
Answer:
Perimeter = 42mlength of the diagonal ≈ 16mStep-by-step explanation:
The Area of the rectangular field is expressed as A = LB and its perimeter
P = 2(L+B)
L is the length of the rectangular field
B is the Breadth of the rectangular field
If the length of a rectangular field is twice its breadth i.e L = 2B and the area is 98m² then;
98 = LB
98 = 2B*B
98 = 2B²
B² = 98/2
B² = 49
B = √49
B = 7m
if B = 7m
L = 98/B
L = 98/7 = 14m
The perimeter of the field P = 2(L+B)
P = 2(14+7)
P = 2*21
P = 42m
The perimeter of the field is 42m.
The length of the diagonal of the field can be expressed using Pythagoras theorem.
d = √L²+B²
d = √14²+7²
d = √196+49
d = √245
d = 15.7m ≈ 16m
Hence, the approximate length of the diagonal of the field is 16m

[tex] {2}^{ \frac{3}{2} } \times {2}^{x} = {2}^{ \frac{8}{5} } [/tex]
Since the left side are in the same base and are multiplying, we add the exponents
[tex] {2}^{ \frac{3}{2} + x } = {2}^{ \frac{8}{5} } [/tex]
Since they have the same base we can equate them
That's
[tex] \frac{3}{2} + x = \frac{8}{5} [/tex]
[tex]x = \frac{8}{5} - \frac{3}{2} [/tex]
[tex]x = \frac{1}{10} [/tex]
Hope this helps you
The speed(S) of a car varies partly directly as its mass(M) and partly directly as the quantity (Q) of fuel in it. When the speed is 80km/hr, the mass is 220kg and the quantity of fuel is 30litres, when the speed is 60km/hr, the mass is 300kg and the quantity of fuel is 40 litres. Find the volume of fuel if the speed is 100km/hr and the mass 250kg. DO NOT WRITE TRASH I WILL REPORT YOU

Answer:
Quantity of fuel is 24 L, based on the model S=2400/Q when S=100
Step-by-step explanation:
If the output power of the car remains constant, the speed would reduce as the masses increase, which is the shown in the observed data.
Hence S does NOT vary directly with the mass and quantity, but varies INVERSELY with the mass and fuel (which has a mass).
Many models are possible to fit the results. Product models with a single constant k
S(m,q) = kmq and S(m,q) = k/mq
do not fit both observation, hence rejected.
A possible model with two constants is shown below
S(m,q) = k1/m + k2/q..................(1)
1. m=220, q=30 => 80 = k1/220 + k2/30 ..........(2)
2. m=300, q=40 => 60 = k1/300 + k2/40 ..........(3)
Solve system (2) and (3) gives k1=0, k2 = 2400.
So it appears that the speed is independent of the mass (m) [unlikely], but inversely proportional to the quantity (q) of fuel, giving
S(q) = 2400/q
When speed = 100 km/h, and mass = 250 kg, substitute
100 = 2400/q => q=2400/100 = 24
