Anna has traveled 20 miles in the taxi.
What is equation?An equation is a relationship between the variables and constants representing how they are related to each other. It includes equal to "=" sign.
The total amount paid is $48. So, the right side of the equation will be 48.
The cost of 1 mile is $2.25 so, the cost of x miles will be 2.25x.
Determine the total cost in terms of x.
Total cost = Fixed Cost+ Variable cost
= 3+2.25x
Determine the equation and solve it.
3+2.25x=48
2.25x=45
x=20
Thus, the taxi has traveled 20 miles.

54. Find [tex]y^{\prime}[/tex] if [tex]x^y=y^x\text{.}[/tex]
Step-by-step explanation:
Take the natural log of both sides:
[tex]ln ({x}^{y} ) = ln ({y}^{x} )[/tex]
Logarithm rules allow you to bring down the exponents:
[tex]yln(x) = xln(y)[/tex]
Now differentiate. We will have to implicitly differentiate 'y' since it is a function of 'x'. Both sides require the product rule:
[tex] \frac{dy}{dx} ln(x) + \frac{y}{x} = ln(y) + \frac{x}{y} \frac{dy}{dx} [/tex]
Isolate the terms that have y' since that is what we want:
[tex] \frac{dy}{dx} ln(x) - \frac{x}{y} \frac{dy}{dx}= ln(y) - \frac{y}{x} [/tex]
Factor out y' to get:
[tex] \frac{dy}{dx}( ln(x) - \frac{x}{y})= ln(y) - \frac{y}{x} [/tex]
Therefore:
[tex] \frac{dy}{dx} = \frac{ln(y) - \frac{y}{x} }{ln(x) - \frac{x}{y} } [/tex]

Fu Da spent a whole day traveling. 5/8 of the journey was spent by the airplane and 1/4 of the remainder was by the train. He spent 6 3/4 h on the bus journey.
a) How long did Fu Da spend on the train journey?
b) How much longer did Fu Da spend on the airplane than on the bus?
Answer:
A) 13.5 Hours
B) 27 Hours
Step-by-step explanation:
So the total journey was 54 hours.
5/8 of that would be 33 and 3/4 hours or how long the airplane journey was.
1/4 would be 13 and a half hours or how long the train journey was
And the remaing amount was the 6 3/4 hours which was the bus journey
So the answers are Fu Da spent 13 and a half hours on the train journey and he spent 27 more hours on the plane than the bus

A bag contains 5 red marbles, 6 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be blue?
Answer:
4.4%
Step-by-step explanation:
The overall probability is the product of the individual probabilities.
Total number of marbles: 15
Original number of blue marbles: 6
First drawing (6 blue and 15 total):
p(blue) = 6/15 = 2/5
Second drawing (5 blue and 14 total):
p(blue) = 5/14
Third drawing (4 blue and 13 total):
p(blue) = 4/13
p(blue followed by blue followed by blue) = 2/5 × 5/14 × 4/13 = 40/910 = 4/91
p(blue followed by blue followed by blue) = 4/91 = 0.043956... = 4.4%
Use a polar coordinate system to plot the point with the given polar coordinates. Then find another representation (r,0) of this point in which:
(a) r> 0, 2x <0 < 4x.
(b) r<0,0<0<2R.
(c) r> 0, -2x <0<0.
(10,pi/3)
Step 1: Plotting the Point
Make a polar coordinate system.
It looks like this ( look at the first photo)
Step 2: Graph the polar function
r=10.
Here since our first coordinate is 10, our radius of our point will be 10.
This basically means we will have a circle with a radius of 10. ( look at the second photo).
Step 3: Look for the angle pi/3,
So that how u graph polar coordinates.
Next, a polar form can have multiple representations.
a. Here we want a radius of to be positve, so our r will stay 10.
We want our angle to lie between 2 pi and 4 pi.
So we just add 2 pi to pi/3.
[tex] \frac{\pi}{3} + 2\pi = \frac{\pi}{3} + \frac{6\pi}{3} = \frac{7\pi}{3} [/tex]
So another angle is
[tex](10, \frac{7\pi}{3} )[/tex]
B. We want r to be negative so
[tex]10( - 1) = - 10[/tex]
And we want our angle to be in between 0 and 2 pi. so we add pi to our angle.
[tex] \frac{\pi}{3} + \pi = \frac{\pi}{3} + \frac{3\pi}{3} = \frac{4\pi}{3} [/tex]
So our new representation is
[tex]( - 10, \frac{4\pi}{3} )[/tex]
C. Finally, we want our r to be positvr and our angle to be negative and in between -2pi and 0.
So we just subtract 2 pi.
[tex] \frac{\pi}{3} - 2\pi = \frac{\pi}{3} - \frac{6\pi}{3} = - \frac{5\pi}{3} [/tex]
So our new representation is
[tex](10, - \frac{5\pi}{3}) [/tex]
A. Transform F using the rule (x, y) → (-x, y)
B. Describe the transformation precisely.
C. Does the transformation result in a a congruent figure?
Answer:
A: Use these points to plot the shapes reflection (-3,4) (-3,6) (-5,6) (-7,4)
B: The transformation would be described as a reflection over the y axis
C: The transformation does result in a congruent figure because the shape doesn't change in size or shape and in length or width
Step-by-step explanation:
So our plots from the figure are: (3,4) (3,6) (5,6) (7,4)
This rule (x, y) → (-x, y) is used for the type of transformation that is a reflection but over the y axis.
So using the rule (x, y) → (-x, y) are new points would be:
(-3,4)
(-3,6)
(-5,6)
(-7,4)

Movies at the rental store are $3.75 each. Snacks and drinks are $1.89 each. Round each amount to the nearest dollar to estimate the cost to rent 3 movies and buy popcorn, a soda, and a candy bar.
Answer:
$14.00
Step-by-step explanation:
First you round 3.75 to 4.00 because 7 is greater than 5 so it would turn the 3 to 4 than add the zeros it's 4.00. Second You multiply by three so 4.00 × 3 you will get 12.00. Than you round 1.89 to 2.00 because 8 is greater than 5 so it would turn to the 1 to the 2 than add the zeros it's 2.00. Finally you add them together and get $14.00
How many distinguishable permutations are there of the letters in BUBBLE?
There are 6 letters, hence 6! = 720 total permutations of BUBBLE. But there are 3 indistinguishable copies of B, so we divide by the number of ways we can rearrange them, 3! = 6. Then there are
6!/3! = 720/6 = 120
distinguishable permutations of BUBBLE.

From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of the circle.
[tex]\large\bold{{Question :}}[/tex]
From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of the circle.
[tex]\large\bold\red{\underline{Solution :-}}[/tex]
Here, O is the center of the circle.
⟼ Given :
OQ = 25 cmPQ = 24 cm⟼ To Find : We have to find the radius OP.
Since QP is tangent, OP perpendicular to QP.
(Since, Tangent is Perpendicular to Radius ⠀⠀⠀⠀⠀⠀⠀at the point of contact)
So, ∠OPQ=90°
⟼ By Applying Pythagoras Theorem :
OP² + RQ² = OQ²
OP² + (24)² = (25)²
OP² = 625 - 576
OP² = 49
OP = √49
OP = 7 cm
Hence, The Radius is 7 cm

A. Isosceles
B. Scalene
C. Acute
D. Right
E. Obtuse
F. Equilateral
A) Isosceles
E) Obtuse
Step-by-step explanation:Ways to Define a Triangle
Triangles can be defined in two ways: by angles and by sides. Equilateral, isosceles, and scalene are based on side length. Acute, right, and obtuse are based on angle measurements. Triangle may only fall under one category for side length and one for angle measure (2 categories total).
Side Length
First, let's define equilateral, isosceles, and scalene.
Equilateral - All 3 sides of the triangle are congruent (equilateral are always acute angles).Isosceles - 2 of the sides are congruent.Scalene - There are no congruent sides; each side has a different length.The triangle above has 2 congruent sides as shown by the tick marks on the left and right sides. This means the triangle is isosceles.
Angle Measurements
Now, let's define acute, right, and obtuse.
Acute - All 3 angles are less than 90 degrees; all angles are acute.Right - 1 of the angles is exactly 90 degrees; it has a right angle.Obtuse - 1 of the angles is greater than 90 degrees; there is an obtuse angle.The largest angle in the triangle is 98 degrees, which is obtuse. This means that the triangle is obtuse.
