A 0.2 kg baseball with a speed of 48 m/s is struck by a bat. The ball rebounds and travels in the opposite direction at 52 m/s. The ball was in contact with the bat for only 2 ms. Find the magnitude of the force of the bat on the ball.
The magnitude of the force of the bat on the ball is 10000 N
From the question given above, the following data were obtained:
Mass (m) = 0.2 KgInitial velocity (u) = 48 m/sFinal velocity (v) = 52 m/sTime (t) = 2 ms = 2×10¯³ sForce (F) =?The magnitude of the force can be obtained as follow:
F = m(v + u) / t
F = 0.2 (52 + 48) / 2×10¯³
F = (0.2 × 100) / 2×10¯³
F = 20 / 2×10¯³
F = 10000 N
Thus, the magnitude of the force is 10000 N

What composition of rigid motions maps ΔPQR to ΔXZY?
A. T<1, 3> ◦ r(270°, O)
B. Rx = 0 ◦ T<0, 2>
C. T<6, 2> ◦ Rx = −2
D. Ry = −2 ◦ T<6, 0>
Answer:
reflection across x=1, translation up 2
units
Step-by-step explanation:
The order of vertices PQR is
clockwise, and the order of XZY
is counterclockwise. This means a
reflection is involved. The longest and
shortest sides are at the left and bottom
of APQR, and at the right and bottom
of AXZY, indicating the reflection is
left-right, not up-down.
Line x=1 contains the midpoints of
segments PX, QZ, and RY, so that is a
suitable line of reflection. Once APQR
is reflected over that line, it needs to be
translated upward 2 units to coincide
with AXZY.
The motions are ...
.
reflection over x=1
translation up 2
.
The motions could also be ...
reflection over y, translation right 2 and
up 2.
ANSWER
The composition of rigid motions maps ΔPQR to ΔXZY is T<6, 2> ◦ Rx = −2. The correct option is C.
What are rigid motion maps?In rigid motion, the position or orientation of the entire set changes without affecting the separation between the line segments. A triangle, for instance, can turn or slide but not extend or squeeze.
PQR's vertices are in clockwise and XZY's are in a counterclockwise sequence. This indicates that a reflection is necessary. The reflection is left-right, not up-down, as evidenced by the longest and shortest sides being on the left and bottom of A PQR, and on the right and bottom of AXZY, respectively.
The midpoints of the segments PX, QZ, and RY are on line x=1, making it a viable line of reflection. To match with AXZY, APQR must be translated upward 2 units after crossing that line.
Therefore, the correct option is C. T<6, 2> ◦ Rx = −2.

The economy has been sluggish in recent months with slow economic growth. Explain the policies that the Federal Reserve could use to improve the economy.(1 point)
The Federal Reserve stops purchasing treasuries and securities, and then issues new reverse repurchase agreements. The short-term profits and decrease in the money supply cause a decrease in interest rates and increased lending.
The Federal Reserve sells treasuries back to banks and issues new reverse repurchase agreements. The decrease in the money supply increases interest rates, which increases lending.
The Federal Reserve purchases treasuries and securities and also issues new repurchase agreements. The increase in the money supply and decrease in interest rates result in more lending and risk.

1. f(x) = 2x^3 -3x. If h(x) is the inverse function of f, then h'(-1) =
I believe the correct answer is 1/3, but I don't know how to get it.
If f and h are inverses of one another, then we have
h(f(x)) = x
Differentiating both sides using the chain rule gives
h'(f(x)) • f'(x) = 1
Let f(x) = -1. Then it would follow that
h'(-1) = 1/f'(x)
for the value of x such that f(x) = -1. This result is known as the inverse function theorem.
Solve for x such that f(x) = -1 :
2x³ - 3x = -1
2x³ - 3x + 1 = 0
By inspection, x = 1 is a solution, since 2 - 3 + 1 = 0. So x - 1 is a factor of the left side; polynomial division yields a factorization of
(x - 1) (2x² + 2x - 1) = 0
and using the quadratic formula, we find three solutions,
x = 1, x = (-1 - √3)/2, x = (-1 + √3)/2
Since there's more than one solution here, this means f(x) is not one-to-one and thus has no inverse in the strict sense of the term.
We can however restrict the domain of f(x) to a subset over which it can be inverted. Using the fact that polynomials are monotonic over intervals between their extrema, we find the critical points of f(x) :
f'(x) = 6x² - 3 = 0 ⇒ x² = 1/2 ⇒ x = ± 1/√2
Check the sign of the second derivative at each critical point:
f''(x) = 12x
• f''(-1/√2) = -12/√2 < 0 ⇒ x = -1/√2 is a local maximum
• f''(1/√2) = 12/√2 > 0 ⇒ x = 1/√2 is a local minimum
Now we have a few choices of how to define the inverse of f(x).
• If we restrict the domain of f(x) to the interval (-∞, -1/√2), then f(x) = -1 when x = (-1 - √3)/2. Then by the inverse function theorem,
f((-1 - √3)/2) = -1 ⇒ h'(-1) = 1/f'((-1 - √3)/2) = (-1 + √3)/6
• If we instead restrict the domain to (-1/√2, 1/√2), then f(x) = -1 when x = (-1 + √3)/2. Then
f((-1 + √3)/2) = -1 ⇒ h'(-1) = 1/f'((-1 + √3)/2) = (-1 - √3)/6
• Otherwise, if we restrict to (1/√2, ∞), then f(x) = -1 when x = 1. Then
f(1) = -1 ⇒ h'(-1) = 1/f'(1) = 1/3
What is the percent rate of increase for the exponential function f (x) = 2.5(1.3)^x
Answer:
f(x) = d/ dx (2.5x1.3)
f(x) =2.5×d/dx(1.3*)
f(x) =5xIn 13/10 x 13*/2×10*
So the answer is
f(x)=5•IN13/10•13*/2•10*
That's the correct answer I see in my book
f(x)=5•IN13/10•13*/2•10* is the percent rate of increase for the exponential function.
What is an exponential function?The formula for an exponential function is f (x) = ax, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
Y=abx y = a b x is the fundamental exponential function equation, where a denotes the y-intercept and b the growth factor.
When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.
f(x) = d/ dx (2.5x1.3)

A 40 N box is pushed 5 m up a ramp. The angle of the ramp is 37° above the horizontal. The applied force is parallel to the ramp and opposed by a frictional force of 10.0 N. Find the net increase in potential energy by the crate.
The net increase in potential energy by the crate is negative 49.4 Joules. That is, ΔP.E = - 49.4 J
Given that a 40N box is pushed 5 m up a ramp. The angle of the ramp is 37° above the horizontal.
We can find the height h of the ramp with the equation below;
h = 5sin 37
h = 3.009 m
Mass of the box = 40/9.8 = 4.082 kg
The maximum energy attained = mgh
Maximum Energy = 4.082 x 9.8 x 3.009
E = 120.36 J
The maximum K.E = Maximum P.E
1/2m[tex]U^{2}[/tex] = 120.36
m[tex]U^{2}[/tex] = 240.72
[tex]U^{2}[/tex] = 240.72 / 4.082
[tex]U^{2}[/tex] = 58.97
U = [tex]\sqrt{58.97}[/tex]
U = 7.7 m/s
We can find the acceleration by using third equation of motion
[tex]V^{2}[/tex] = [tex]U^{2}[/tex] - 2aS
Since the box is going to rest, V = 0, and acceleration will be negative
0 = 7.7^2 - 2 x a x 5
10a = 59.29
a = 59.29/10
a = 5.93 m/[tex]s^{2}[/tex]s^2
The applied force F = ma
F = 4.082 x 5.93
F = 24.2 N
Given also that the applied force is parallel to the ramp and opposed by a frictional force of 10.0 N. The net increase in potential energy by the crate will be
ΔP.E = Net work done
ΔP.E = Net force x distance
ΔP.E = (24.2 - 10 - 40sin37) x 5
ΔP.E = - 9.87 x 5
ΔP.E = - 49.4 J
Therefore, The net increase in potential energy by the crate is negative 49.4 Joules.
