The transformation function of the given exponential function is -1/4, -1, -4, -16, -64. Hence option D is correct.
What is an exponential function?An exponential function is a mathematical relation to find exponential growth or decay for the given data. It represents the constant change in independent variables and gives the same proportional change.
The exponential function is expressed as f(x) = exp (x) or eˣ where x is variable and e is constant which is called the base of the equation.
From the given,
the exponential function f(x) = 1/4, 1,4,16,64
The transformation function G(x) is the inverse of the exponential function and is equal to -1/4,-1, -4,-16,-64.
Hence, the ideal solution is option D.

If the wind is blowing from north to south, where are the areas of high and low pressure?
Answer:
Wind is caused by differences in the atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds.
Our Earth is a rotating planet. Fast moving air is deflected by the Coriolis effect, except exactly on the equator. This defines the direction of cyclones, hurricanes, and typhoons rotation. The wind flow around a large cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
Wind forms when the sun heats one part of the atmosphere differently than another part. This causes expansion of warmer air, making less pressure where it is warm than where it is cooler. Air always moves from high pressure to lower pressure, and this movement of air is wind.
The high is west of you, and the low is east of you. (If you're in the northern Hemisphere.)

Please help me to solve this question .
Answer:
P1 = momentum before collision = .5 kg * .32 m/s = .16 kg-m/s
Momentum is conserved
P1 = P2 = V * (M + m) = .16 kg-m/sec
V = .16 kg-m/sec / (.5 kg + .3 kg) = .2 m/sec
An book fell from a shelf 1.5 meters from the ground. If it took the book 3 seconds to hit the ground, what was the velocity of the book?
The initial velocity of the book before its hits the ground is 14.2 m/s.
The given parameters;
height of the book above the ground, h = 1.5 mtime of motion of the book, t = 3 secondsThe initial velocity of the book is calculated as follows;
h = ut + ¹/₂gt²
where;
u is the velocity of the book1.5 = 3u + (0.5 x 9.8 x 3²)
1.5 = 3u + 44.1
3u = 1.5 - 44.1
3u = -42.6
[tex]u = \frac{-42.6}{3} \\\\u = -14.2 \ m/s\\\\u = 14.2 \ m/s \ downwards[/tex]
Thus, the initial velocity of the book before its hits the ground is 14.2 m/s.

why is the saturated lapse rate less than the dry adiabatic lapse rate?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.
Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.
a tennis ball is launched from the floor at a velocity of 90 m/a at an angle of 13 degrees to the horizontal. calculate its range
Answer:
~186
Explanation:
1) R= (V^2 × sin A ) /g
V=90 m/a
A= 13°
g= 9.8 or 10 (I will take 9.8 for right result)
R= (90^2 × sin 13) / 9.8 = 185.928932672 ~ 186

Which is true for every atom of an element?
A.
It can be seen with a magnifying glass.
B.
It is joined together with another atom.
C.
It has mass and volume.
D.
It is weightless.
Answer:
A
Explanation:
Every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.
What is the matter?Anything which has mass to keep the same when comparing the hardness of the solid and occupies space is known as matter, mainly there are four states of matter solid liquid gases, and plasma.
As given in the problem statement we have to find the true statement from the given options that is true for every atom of an element,
The size of an atom of an element is a very small order of magnitude so it can not be seen with a magnifying glass, therefore, option A is not the correct response.
Thus, every atom of an element has its own mass and volume as the atom is the smallest fundamental unit of the matter, therefore the correct answer is option C.

Which statement explains whether or not a person should use an experiment of a ball rolling down a hill as evidence that the force of gravity pulls objects straight down?(1 point) They should use it. Any experiment on Earth involving natural motion will provide direct evidence that gravity pulls objects straight down. They should use it. Any experiment on Earth involving natural motion will provide direct evidence that gravity pulls objects straight down. They should not use it. The experiment has several dimensions of motion, including one parallel to the ground, so the motion of the ball does not directly test the force of gravity. They should not use it. The experiment has several dimensions of motion, including one parallel to the ground, so the motion of the ball does not directly test the force of gravity. They should use it.

The experiment shows the ball falls toward the bottom of the hill, so it provides direct evidence that gravity pulls an object downward. They should not use it. Gravity should be tested in space, and this experiment could only be tested on Earth.
The ball raised up the hill is given gravitational potential energy, which
causes it to roll spontaneously down the hill.
The statement that explains whether the ball rolling down the hill
experiment should be used is; The experiment shows the ball falls toward
the bottom of the hill, so it provides direct evidence that gravity pulls an
object downward. They should use it.
Reason:
The equation for the velocity of a ball falling down a hill is [tex]v = \sqrt{\dfrac{10}{7} \cdot g \cdot h}[/tex]
Therefore, by increasing the height from which the ball rolls down the hill,
the velocity of the ball increases, which indicates that the ball is
accelerating, and therefore, being acted on by a force, the force of gravity.
Therefore;
Given that the ball falls or moves with increasing speed towards
the bottom of the hill, which shows that the motion is due to Earth's pull
known as the gravitational force, the experiment should be used.

what happens to kinetic energy as speed doubles and mass doubles
Answer:
If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision....What happen to the kinetic energy of its velocity become double ? The energy possessed by a body because of its motion, equal to one half the mass of the body times the square of its speed is called its kinetic energy. Hence, when velocity is doubled, kinetic energy becomes 4 times.
Explanation:
Answer: It increases by four times
Explanation: If you double the mass of an object, you double the kinetic energy. If you double the speed of an object, the kinetic energy increases by four times. Kinetic energy can be passed from one object to another in the form of a collision.
A force unit is defined as the product of a mass unit and a unit of
acceleration.
time.
velocity.
displacement.
Answer:
A force unit is defined as the product of a mass unit and a unit of acceleration.
Answer:
Force can be defined as a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object.
Explanation:
Force = M (Mass) * A (Acceleration)
The SI unit of Mass = KG
S.I. unit of acceleration is m/sec/sec = m/sec2
Hence, Unit of force is Kg m/Sec2
Since force is used so often, S. I. gives this unit a special name:
1 Newton = 1 kg m/sec2

Apply Newton’s second law to calculate the frictional force needed to hold a 15 g pen in your fingers and keep it from falling
Answer:
0.1962N.
Explanation:
Weight is a force, so we use newtons second law which states F=ma. So the weight of a watermelon on earth is 2kg x 9.81m/s², which is 19.62N (newtons). On the moon it weighs 2 x 1.63 which is 3.26N.
The weight of the pen is 0.02 x 9.81, which is 0.1962N. If the pen is not to fall the frictional force needs to be equal to this force,
so the answer is 0.1962N.
