Therefore, the common difference of the arithmetic sequence is 9.
To find the common difference of an arithmetic sequence, we can use the formula:
a_n = a_1 + (n - 1) * d,
where:
a_n is the nth term of the sequence,
a_1 is the first term of the sequence,
n is the position of the term in the sequence, and
d is the common difference.
Given that a_1 = 2 and a_5 = 38, we can substitute these values into the formula:
a_5 = a_1 + (5 - 1) * d
38 = 2 + 4d
Now we can solve for d:
38 - 2 = 4d
36 = 4d
d = 36 / 4
d = 9

Ming's recipe for sweet tea calls 4 teaspoon of sugar. If Ming wants to make the tea 25% less sweet, how much less sugar should he use??
PLEASE EXPLAIN AND HELPP
Answer:
Ming should use 3 teaspoons instead of 4.
Step-by-step explanation:
If you imagine each teaspoon as 25% of 100% then it is a lot easier. If Ming's tea needs to be 25% less sweet, then he should only use 75% of the sugar aka 3 tespoons. Hope this helps and good luck

Answer:
x = 14
Step-by-step explanation:
Vertical angles are congruent , then
7x - 27 = 3x + 29 ( subtract 3x from both sides )
4x - 27 = 29 ( add 27 to both sides )
4x = 56 ( divide both sides by 4 )

Whats the volume of the cylinder? Round your answer to the nearest hundred the top is B the left side of the cylinder is 13cm the bottom of the cylinder is 4cm so whats the volume of it?
Answer:
The volume of the cylinder is 163.3 m³.
Step-by-step explanation:
Given that,
Height = 13 cm
Base = 4 cm
So, radius = 2 cm
We need to calculate the volume of the cylinder
Using formula of cylinder
\(V=\pi r^2h\)
Where, r = radius
h = height
Put the value into the formula
\(V=\pi\times(2)^2\times13\)
\(V=163.3\ cm^3\)
Hence, The volume of the cylinder is 163.3 cm³.

Express your distance in "car lengths" (about 15 feet). car lengths multiple car crashes when one of the cars in a line suddenly slows down. The question we want to answer is: "How close is too close?"
Reaction time refers to the time it takes for someone to respond to a stimulus. It's composed of two components: perception time and decision time.
The time it takes to move your foot from the gas pedal to the brake pedal can be estimated using the formula r=(5 m/s2 )=t1/2 , and the total reaction time is t1+t2. The acceleration magnitude, -a0, can be calculated using this formula: -a0 = Δv/t.
When we use the negative sign in front of the acceleration magnitude, we indicate that it is directed in the opposite direction of motion.
To calculate how far the car in front of you will travel before it stops, use the formula s = vi*t + 0.5*a*t2. The average velocity during this time interval is the displacement divided by the time.
Using the values from parts A and B, the distance you travel before applying the brakes is 44 meters, and the total distance you travel before stopping is 70 meters.
If you do not detect that the car in front of you is braking for one second, you will travel an additional 28 meters.
The recommended safe distance to stay behind a car at 60 mph is 3 car lengths.
The question deals with estimating the reaction time of a driver and the distance one would travel before coming to a halt in an emergency.
It is important to know the reaction time because it can help reduce the number of accidents caused by a driver's lack of responsiveness.
The formula r = (5 m/s2) = t1/2 can be used to estimate the time it takes to move one's foot from the gas pedal to the brake pedal.
This reaction time is composed of two components: perception time and decision time. When a driver detects a stimulus and decides how to react, these two components are used.
The magnitude of acceleration, -a0, can be calculated using this formula: -a0 = Δv/t.
When we use the negative sign in front of the acceleration magnitude, we indicate that it is directed in the opposite direction of motion. This formula assumes that the acceleration is constant, which is reasonable for small time intervals.
The distance that the car ahead of you will travel before stopping can be calculated using the formula s = vi*t + 0.5*a*t2, where s is the distance traveled, vi is the initial velocity, t is the time it takes to stop, a is the acceleration, and t2 is the time it takes to travel s meters.
The average velocity during this time interval is the displacement divided by the time.
To calculate the distance you travel before applying the brakes, use the formula s = vt + 0.5*a*t2. In this case, the distance is calculated using the driver's reaction time, which is t1 + t2.
If you do not detect that the car in front of you is braking for one second, you will travel an additional 28 meters. This suggests that drivers should be cautious and keep a safe distance from the vehicle in front of them to avoid accidents. The recommended safe distance to stay behind a car at 60 mph is 3 car lengths.

Which statement is correct?
a
Block A has the greatest density.
b
Block B has the greatest density.
c
The density of Block A is equal to the density of Block B.
d
The density of Block B is equal to the density of Block C.
Answer:
b
Block B has the greatest density.
Step-by-step explanation:
density = mass/volume
volume = length × width × height
All blacks have the dimensions 7 cm by 3 cm by 1 cm, so the 3 volumes are equal.
Since density = mass/volume, and the volumes are equal, the block with the highest mass has the highest density.
Since all the masses are different, all densities are different.

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to
rent a canoe. Write and graph an equation representing the cost, y, of renting a
canoe for × hours.
The equation representing the cost of the canoe rental company is given by y = 30x + 20 .
Let the total cost for renting a canoe be y.
Let the canoe is being rent for x hours.
now the cost for renting the canoe at 30 dollars per hour = 30x
Total cost of renting the canoe = 30x + 20
But the total cost is y.
Hence the equation to represent this situation is given by
y = 30x + 20 which is a straight line of the form y = mx +c, where the slope is 30 and the y-intercept is 20.
Now we will plot the graph for this equation.
At x = 0 , y = 20
At x = 1 , y = 50
At x= -3 , y = -70
Hence the graph of the line passes through these points on the cartesian plane.

S borrowed a loan of Rs 20000 from a person at 6% per annum simple interest and lent the same money as a loan to a businessman at the same rate of interest compounded annually. How much amount does he get the profit after 2 years? Find it.
PLEASE GIVE BRAINLIEST!
First, let's calculate the interest S paid on the loan he borrowed:
Simple interest for 2 years = (principal x rate x time) / 100
= (20000 x 6 x 2) / 100
= 2400
So, S paid Rs 2400 as simple interest on the loan he borrowed.
Now, let's calculate the amount of money S lent to the businessman:
Amount = principal x (1 + rate/100) ^ time
= 20000 x (1 + 6/100) ^ 2
= 20000 x 1.1236
= 22,472So, S lent Rs 22,472 to the businessman.
Now, let's calculate the interest earned by S on this loan after 2 years:
Compound interest for 2 years = amount - principal
= 22,472 - 20,000
= 2,472
So, S earned Rs 2,472 as interest on the loan he gave to the businessman.
Finally, let's calculate the profit earned by S after 2 years:
Profit = Interest earned - Interest paid
= 2,472 - 2,400
= 72
Therefore, S earns a profit of Rs 72 after 2 years.

We are to show that \(\sqrt{3} cosec140^{0} - sec140^{0} = 4\\\)
Proof:
From trigonometry identity;
\(cosec \theta = \frac{1}{sin\theta} \\sec\theta = \frac{1}{cos\theta}\)
\(\sqrt{3} cosec140^{0} - sec140^{0} \\= \frac{\sqrt{3} }{sin140} - \frac{1}{cos140} \\= \frac{\sqrt{3}cos140-sin140 }{sin140cos140} \\\)
From trigonometry, 2sinAcosA = Sin2A
\(= \frac{\sqrt{3}cos140-sin140 }{sin140cos140} \\\\= \frac{\sqrt{3}cos140-sin140 }{sin280/2}\\= \frac{4(\sqrt{3}/2cos140-1/2sin140) }{2sin280}\\\\= \frac{4(\sqrt{3}/2cos140-1/2sin140) }{sin280}\\since sin420 = \sqrt{3}/2 \ and \ cos420 = 1/2 \\ then\\\frac{4(sin420cos140-cos420sin140) }{sin280}\)
Also note that sin(B-C) = sinBcosC - cosBsinC
sin420cos140 - cos420sin140 = sin(420-140)
The resulting equation becomes;
\(\frac{4(sin(420-140)) }{sin280}\)

solve the equation 4x^3 + 32x^2 + 42x - 16 = 0, given that one root is equal to the sum of the other two roots
The solutions to the equation are x = -1, x = -8, and x = 1/2.
How to calculate the valueThe equation 4x³ + 32x² + 42x - 16 = 0 can be divided throuh by 2 as follows:
2x³ + 16x² + 21x - 8 = 0
We can test each of these possible roots by substituting them into the equation and seeing if we get 0. When we substitute -1, we get 0, so -1 is a root of the equation. We can then factor out (x + 1) from the equation to get:
(x + 1)(2x² + 15x - 8) = 0
We can then factor the quadratic 2x² + 15x - 8 by grouping to get:
(x + 8)(2x - 1) = 0
This gives us two more roots, x = -8 and x = 1/2.
Therefore, the solutions to the equation are x = -1, x = -8, and x = 1/2.
