Vertical translation 3 units up.
Vertical translation 3 units down.
The transformations that are needed to transform the graph of f(x) to the graph of g(x) include the following:
Horizontal translation 1 unit left.Vertical translation 3 units down.What is a translation?In Mathematics, the translation of a geometric figure to the right simply means subtracting a digit from the value on the x-coordinate (x-axis) of the pre-image and translating a geometric figure down simply means subtracting a digit from the value on the y-coordinate (y-axis) of the pre-image.
Given the following function:
Function, f(x) = 4^x
Next, we would translate f(x) 1 unit left based on this horizontal translation rule:
f'(x) = f(x + 1)
f'(x) = 4^{x + 1}
Now, we would apply a vertical translation 3 units down based on this horizontal translation rule:
f''(x) = f'(x) - 3
f''(x) = 4^{x + 1} - 3
Therefore, function g(x) = 4^{x + 1} - 3

Casho went shopping for a new pair of sneakers because of a sale. The price on the tag was $25, but Casho paid $22.50 before tax. Find the percent discount
The percentage discount for the pair of sneakers is 10%.
What is percentage?A percentage is a value per hundredth. Percentages can also be fractions and decimals by decimals by dividing by 100 and vice versa. To obtain a percentage of a given value we divide the given percentage by a hundred and multiply the value with it.
The percentage discount can be determined by putting the discounted value upon the price multiplied by a hundred and subtracting the obtained percentage from the hundred percentage.
∴ The percentage discount on the pair of sneakers is,
= (22.50/25)×100.
= 0.9×100.
= 90%.
So, the percentage discount is (100 - 90)% = 10%.

7. What is the cost of a book that was sold for $500 and at a profit of $ 230?
The most appropriate choice for Profit and loss will be given by-
Cost price of the book is $270
What is Profit and loss?
The price at which an article is bought is known as cost price and the price at which the article is sold is known as selling price.
If the selling price of an article is more than the cost price, the difference between the selling price and the cost price gives the profit.
If the selling price of an article is less than the cost price, the difference between the cost price and the selling price gives the loss.
Here,
Selling price of book = $500
Profit = $230
In case of profit, cost price is always less than the selling price
Cost price of the book = Selling price - profit

ABCDE is a circle centre O. The diameter, AC, is extended to the point F so that CF = 16 cm. The line BF is the tangent to the circle at B and FDE is a straight line such that FD = 18 cm and DE = 14 cm. The radius of the circle is r
Answer:
r = 10 cmStep-by-step explanation:
It is assumed you are looking for the missing value of r.
Use the intersecting secants theorem:
[tex]FA*FC = FE*FD[/tex]Substitute known values and solve for r:
(2r + 16)*16 = (14 + 18)*1832r + 256 = 57632r = 320r = 10Answer:
(a) FB = 24 cm
(b) r = 10
Step-by-step explanation:
Part (a)Find the length, in cm, of FB.
Intersecting Secant and Tangent Theorem
When a secant segment and a tangent segment meet at an exterior point, the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
Given:
Tangent segment = FBSecant segment = FE = 18 + 14 = 32 cmExternal secant segment = FD = 18 cm[tex]\begin{aligned}\implies FB^2 & =FE \cdot FD\\FB^2&=32 \cdot 18\\FB^2&=576\\\sqrt{FB^2}&=\sqrt{576}\\FB&=24\end{aligned}[/tex]
Therefore, the length of FB is 24 cm.
Part (b)Find the value of r.
Triangle FBO is a right triangle with side lengths:
BO = r cmFB = 24 cmOF = (r + 16) cmPythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right triangle.c is the hypotenuse (longest side) of the right triangle.Therefore, substitute the side lengths of triangle FBO into Pythagoras Theorem and solve for r:
[tex]\begin{aligned}\implies BO^2+FB^2&=OF^2\\r^2+24^2&=(r+16)^2\\r^2+576&=r^2+32r+256\\576&=32r+256\\32r&=320\\r&=10\end{aligned}[/tex]
Therefore, the value of r is 10.

Answer: Two concentric circles have radii $1$ and $2$. Two points on the outer circle are chosen independently and uniformly at random. What is the probability that the chord joining the two points intersects the inner circle?
$\textbf{(A)}\ \frac{1}{6}\qquad \textbf{(B)}\ \frac{1}{4}\qquad \textbf{(C)}\ \frac{2-\sqrt{2}}{2}\qquad \textbf{(D)}\ \frac{1}{3}\qquad \textbf{(E)}\ \frac{1}{2}\qquad$
Solution
Let the center of the two circles be $O$. Now pick an arbitrary point $A$ on the boundary of the circle with radius $2$. We want to find the range of possible places for the second point, $A'$, such that $AA'$ passes through the circle of radius $1$. To do this, first draw the tangents from $A$ to the circle of radius $1$. Let the intersection points of the tangents (when extended) with circle of radius $2$ be $B$ and $C$. Let $H$ be the foot of the altitude from $O$ to $\overline{BC}$. Then we have the following diagram.
[asy] scale(200); pair A,O,B,C,H; A = (0,1); O = (0,0); B = (-.866,-.5); C = (.866,-.5); H = (0, -.5); draw(A--C--cycle); draw(A--O--cycle); draw(O--C--cycle); draw(O--H,dashed+linewidth(.7)); draw(A--B--cycle); draw(B--C--cycle); draw(O--B--cycle); dot("$A$",A,N); dot("$O$",O,NW); dot("$B$",B,W); dot("$C$",C,E); dot("$H$",H,S); label("$2$",O--(-.7,-.385),N); label("$1$",O--H,E); draw(circle(O,.5)); draw(circle(O,1)); [/asy]
We want to find $\angle BOC$, as the range of desired points $A'$ is the set of points on minor arc $\overarc{BC}$. This is because $B$ and $C$ are part of the tangents, which "set the boundaries" for $A'$. Since $OH = 1$ and $OB = 2$ as shown in the diagram, $\triangle OHB$ is a $30-60-90$ triangle with $\angle BOH = 60^\circ$. Thus, $\angle BOC = 120^\circ$, and the probability $A'$ lies on the minor arc $\overarc{BC}$ is thus $\dfrac{120}{360} = \boxed{\textbf{(D)}\: \dfrac13}$.

On a map, Elmwood Drive passes through R(4,-11) and S(0,-9) and Taylor Road passes through
J(6,-2) and K(4,-5). If the streets are straight lines, determine if the streets are parallel or
perpendicular.
The streets where Elmwood and Taylor drive are neither perpendicular nor parallel.
Elmwood Drive passes through R(4,-11) and S(0,-9)
Slope of this line is (y₁-y₂)/(x₁-x₂)
Here (x₁,y₁) is (4,-11) and (x₂,y₂) is (0,-9)
slope of this line is (-11 - (-9))/(4-0)
= (-11 + 9)/4
= -2/4 = -1/2
Taylor Road passes through J(6,-2) and K(4,-5)
Slope of this line is (y₁-y₂)/(x₁-x₂
Here (x₁,y₁) is (6,-2) and (x₂,y₂) is (4, -5)
slope of this line is (-2 - (-5))/(6 - 4)
= (5 - 2)/2
= 3/2
The slopes of both the line is not same, so they are not parallel.
The product of slopes of both the lines is equal to 1, then it can be said as perpendicular lines.
The product of slope of streets passed by Elmwood and Taylor is
- 1/2 x 3/2 = -3/4
The result is not equal to 1, so they are not perpendicular lines.
Therefore, the streets where Elmwood and Taylor drive are neither perpendicular nor parallel.

What is translation?Translation is the act of moving a form or a figure from one location to another. A figure can move in translation up, down, right, left, or anyplace else in the coordinate system. Only the object's location changes during translation; its size stays the same.
In mathematics, a translation is the up, down, left, or right movement of a form. Because the translated shapes appear to be exactly the same size as the original ones, they are consistent with one another. Just one or more routes have been altered.
Given:
f(x) = |x|
The graph given here is reflected over x- axis.
Now, to make it up- side down the parent function should be negative.
So, g(x)= -f(x)
then, the graph is also shifted 3 units up.
Thus, g(x)= -f(x) + 3
y = -f(x) +3
Hence, the equation of the graphed function is y = -f(x) +3.
