Using transformations, it is found that the transformation from [tex]y = \sqrt[3]{x}[/tex] to [tex]y = \sqrt[3]{0.5x}[/tex] is:
It is horizontally stretched by a factor of 1/2.
What are transformations on the graph of a function?Transformations in the graph of a function happens when operations such as multiplication/division or sum/subtraction are applied in the definition of the function.
They can be either in the domain of the function, involving values of x, or the range, involving values of y.
For this problem, the change was that x -> x/2, that is, there was a multiplication in the domain, meaning that there was an horizontal stretch to the function.
The fact that the number was multiplied by 1/2 means that the factor of the stretch is of 1/2.
What is the missing information?The transformation is from [tex]y = \sqrt[3]{x}[/tex] to [tex]y = \sqrt[3]{0.5x}[/tex].

About how many times heavier is the largest dog when compared with the smallest dog?
The number of times heavier that the largest dog is when compared with the smallest dog is B. 41.
How to illustrate the information?It should be noted that from the information given, the biggest dig is the St Bernard and it has 145 pounds.
Also, it should be noted that the smallest dog is Yorkie and it had 3.5 pounds. Therefore, it should be noted that the number of times heavier will be:
= Weight of biggest fog / Weight of smallest dog
= 145 / 3.5
= 41.

What is speed?The speed of an item, which is a scalar quantity in everyday usage and kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time. Speed is what it means. the speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.
Given Data
The speed, s, is measured in miles per hour, and distance, y, is
measured in yards.
The line of fit is given by ý = 3.98 +53.59s.
When s = 5 sec
y = 3.98 + 53.59(5)
y = 3.98 + 267.95
y = 271.93
The predicted distance of the ball is 271.93 feet.

What is density?The density of a place refers to the quantity of things—which may include people, animals, plants, or objects—there are in it. Divide the number of objects by area's measurement to determine density. A country's population density is calculated by dividing its total population by its area, expressed in the square kilometers or miles.
A flat distribution with the same probability density for each number is called a uniform distribution. The area beneath the distribution's graph must be 1. This distribution has a range of 10.0 and runs from 46.0 to 56.0 minutes (56.0-46.0). Since the density must be 1/10, 10.0*0.1 Equals 1.0.
Multiply the range between the numbers by the probability density to get the likelihood of being between two numbers
range: 50.75-50.5 = 0.25
0.25*0.1 = 0.025
P(50.5 < x < 50.75) = 0.025

You have $50 in your bank account. Each week you plan to deposit $8 from your allowance and $20 from your paycheck. The equation b=50+(20+8)w gives the amount b in your account after w weeks. How many weeks from now will you have $210 in your bank account?
If you have $50 in your bank account and each week you plan to deposit $8 from your allowance and $20 from your paycheck. The number of weeks from now that you will have $210 in your bank account is: 5.71w.
Number of weeksThe given equation is:
b=50+(20+8)w
Where:
b is the amount in your account after w weeks.
w = Number of week
Hence,
b = 50+(20+8)w
b = 50+28w
b-50 = 28w
(b-$50)/28 = w
(210-$50)/28 = w
160/28 = w
5.71 = w
Therefore we can conclude that you will have the amount of $210 in your account in 5.71 weeks.

The description of the one transformation that maps ∆ABC to ∆A'B'C' is a rotation counterclockwise, 90 degrees, with the center at the origin
What is a rotation transformation?A rotation transformation can be described as the angular motion of a rigid, geometric figure around a point
The vertices on the triangle ∆ABC are;
A(-5, -2), B(-7, -4), C(-5, -5)The vertices on the triangle ∆A'B'C' are;
A'(2, -5), B'(4, -7), C'(5, -5)The rotation of a point A(x, y), 90° counterclockwise about the origin gives the point A'(-y, x)
The reflection of a point (x, y) across the y–axis gives the point A'(-x, y)
Therefore;
The coordinates of the vertices of∆ABC following a 90° counterclockwise rotation gives;
A(-5, -2) → A'(2, -5)
B(-7, -4) → B'(4, -7)
C(-5, -5) → C'(5, -5)
Therefore;
The transformation that maps ∆ABC to ∆A'B'C' is therefore a rotation of 90° counterclockwise about the origin

m^2+7m-51/4=0 by completimg square
By completing squares, we will see that the two solutions of the quadratic equaiton are:
m = -7 + √(145)/2
m = -7 - √(145)/2
How to solve by completing squares?Here we have the quadratic equation:
m^2 + 7m - 51/4 = 0
If we multiply both sides by 4, we will get
4m^2 + 28m - 51 = 0
Now, remember the relation:
(a + b)^2 = a^2 + 2ab + b^2
Then to complete the squares we can write:
(2m)^2 + 2*14*m + (14)^2 - (14)^2 - 51 = 0
(2m + 14)^2 - 14^2 - 51 = 0
(2m + 14)^2 = 145
We already completed squares, now the solutions are:
2m = -14 ± √145
m = (-14 ± √145)/2
m = -7 + √(145)/2
m = -7 - √(145)/2

Suppose an online store has an item on sale for 10% off the original price. By what perceny does the store have to increase the price of the item in order to sell it for the original amount
The most appropriate choice of percentage will be given by-
The store have to increase the price of the item by [tex]11\frac{1}{9}[/tex] % in order to sell it for the original amount.
What is Percentage?
Percentage is a ratio expressed as a percentage of 100.
Let the original price be x
Percentage decrease in price due to sale = 10%
Decrease in price due to sale = [tex]\frac{10}{100} \times x[/tex]
= [tex]\frac{x}{10}[/tex]
New price = ([tex]x - \frac{x}{10}[/tex])
= [tex]\frac{10x-x} {10}[/tex]
= [tex]\frac{9x}{10}[/tex]
Now,
Increase in price from [tex]\frac{9x}{10}[/tex] to [tex]x[/tex] = [tex]\frac{x}{10}[/tex]
Percentage by which the store have to increase the price of the item in order to sell it for the original amount =
[tex]\frac{\frac{x}{10} }{\frac{9x}{10} } \times 100[/tex]
=[tex]\frac{x}{10} \times \frac{10}{9x} \times 100[/tex]

Juan bought apples and
bananas.
Answer:
2 apples and 4 bananas
Step-by-step explanation:
Given info:
He bought $4 worth of apples and bananas. Each apple costs $1 and each banana costs $0.50. He bought a total of 6 apples and bananas altogether.Question given:
Determine the number of apples, x, and the number of bananas, y, that Juan bought.
Solution:
Since, we know that;
apples = x
bananas = y
Cost of each apple = $1 & Cost of each banana = $ 0.50
Total = 6
The equation that represents the following information:
x + y = 6
x + 0.5y = 4
We can multiply the top equation by -1 so it becomes -x -y = 6
-x - y = 6
x + 0.5y = 4
Now, we can use elimination to cancel out the x.
-0.5y = -2
y = 4
Because y=4, x must be 2 since x+y=6. So,
x = 2 and y = 4
Which means;
Juan bought 2 apples and 4 bananas.
