Rewrite the following statement using a number in scientific notation.
My new music player has a capacity of 300 gigabytes. (Recall that giga means billion.)
Answer: My new music player has a capacity of 3 * 10^11 bytes.
Step-by-step explanation: giga=billion=10^9. 300 in scientific notation is 3*10^2. Since 3 is between 1 and 10. So 10^2 * 10^9=10^11.
Find each missing measure
Answer:
<U = 54
<T = 72
Step-by-step explanation:
Find the angle measures
The marks on the sides means the sides are the same length
That means the base angles have the same measurement
<S = <U = 54
The sum of the angles of a triangle equals 180
<S + <U + < T = 180
54 + 54 + < T =180
108 + < T =180
<T =180-108
<T = 72
Answer:
m<U = 54°
m<T = 72°
Step-by-step explanation:
According to the isosceles triangle theorem ( If two sides of a triangle are equal , then the angles opposite to these sides are also equal. ),
ST = UT
So,
m<S = m<U.
Given that,
m<S = 54°
So,
m<U = 54°
Also, we know that the sum of the interior angles of a triangle is added up to 180 degrees.
So,
m<S + m<U + m<T = 180°
54° + 54° + m<T = 180°
108° + m<T = 180°
m<T = 180° - 108°
m<T = 72°

Solution
The diagram given is a right angle triangle
To find the value of x; we consider the relationship between the three sides.
Pythagoras theorem actually gave the relationship between the three sides of a right angle triangle.
By Pythagoras theorem;
[tex]\begin{gathered} x^2+8^2=13^2 \\ \\ \Rightarrow x^2=13^2-8^2 \\ \\ \Rightarrow x^2=169-64 \\ \\ \Rightarrow x^2=105 \\ \\ \Rightarrow x=\sqrt{105} \end{gathered}[/tex]x = 10.25

To solve this question we will compute the magnitude of each vector.
Recall that the magnitude of a vector
[tex]a\hat{i}+b\hat{j}[/tex]is:
[tex]\parallel a\hat{i}+b\hat{j}\parallel=\sqrt[]{a^2+b^2}.[/tex]Therefore, the speed of the first car is:
[tex]\parallel26\hat{i}+31\hat{j}\parallel=\sqrt[]{26^2+31^2}\text{.}[/tex]Simplifying the above equation we get:
[tex]\parallel26\hat{i}+31\hat{j}\parallel=\sqrt[]{676^{}+961}=\sqrt[]{1637}\approx40.46.[/tex]The speed of the second car is:
[tex]\parallel40\hat{i}\parallel=\parallel40\hat{i}+0\hat{j}\parallel=\sqrt[]{40^2+0^2}\text{.}[/tex]Simplifying the above equation we get:
[tex]\parallel40\hat{i}\parallel=\sqrt[]{40^2}=40\text{.}[/tex]Answer:
The first car is the faster car.
Speed= 40.46.
In each figure, a is parallel to b. Determine whether the third figure is a translation image of the first figure. Write yes or no. Explain your answer. A line is reflected across line a, another line is reflected across line b to form a third line. a. Yes; it is one reflection after another with respect to the two parallel lines. b. No; it is a reflection followed by a translation. c. No; it is a reflection followed by a rotation. d. No; it is one reflection after another with respect to the two parallel lines. Please select the best answer from the choices provided A B C D
To determine whether the third figure is a translation image of the first figure, we say that; B: No; it is a reflection followed by a translation
How to Interpret Transformation of a figure?Transformation could be reflection, translation, rotation or even dilation.
Reflection can be thought of as the mirror image of a shape across a line.
Rotation is when one turns an object around a point
Translation is simply moving an object from one point to another without any change of dimension.
If we look at the given three figures in the attached image, we can see that the second image is the reflection or mirror image of the first figure.
After reflection, we can see that it is undergoes translation, which means it is moved apart from the first figure.
Thus, the third figure is a reflection of the first figure, and then it is translated.

Figure A is translated 3 units right and 2 units up. The translated figure is labeled figure B. Figure B is reflected ove
the x-axis. The reflected figure is labeled figure C. Which best explains why figure A is congruent to figure C?
Its A, A is congruent to B and B is congrument to c
The translation equation, often known as the vertical translation equation, is g(x) = f(x+k) + C.Because the triangles are not congruent, Figure B is not an exact replica of Figure A.
In what direction does a figure move on a coordinate grid?
An example of one of these is a translation. A geometric figure moves in the coordinate plane when it slides up, down, left, or right. The figure shifts its position but maintains its original orientation. Additionally, it maintains its size and shape.
The vertical translation equation, or the formula for translation, is g(x) = f(x+k) + C.

Gregoria borrowed $2,450, to be paid back at 3.5% annual simple interest. She repays $3,221.75. How many years was the loan period?
The loan that was borrowed by Georgina was for a period of 9 years.
How to calculate the value?From the information, Gregoria borrowed $2,450, to be paid back at 3.5% annual simple interest. She repays $3,221.75. The Interest will be:
= $3,221.75 - $2,450
= $771.75
Therefore, the time taken for the loan will be expressed as:
Interest = PRT/100
where P = Principal
R = Rate
T = Time.
Interest = PRT/100
771.75 = (2450 × 3.5 × T) /100
Cross multiply
8575T = 77175
Time = 77175 / 8575
Time = 9

Please answer question 5 and 6.
5.Given the functions f(x)=-2x + 4 and g(x) = 2x- 8, find the value of x for which f(x) = g(x).
6.Graph the function
Based on the definition of the functions, the value of x if f(x) = g(x) is 3
How to determine the value of x?The equations of the functions are given as
f(x) = -2x + 4
g(x) = 2x - 8
It should be noted that the above equations are linear equations
From the question, we understand that the functions are equal
This means that, we have the following equation
f(x) = g(x)
Substitute the known values in the above equation
So, we have the following equation
-2x + 4 = 2x - 8
Collect the like terms in the above equation
So, we have
2x + 2x = 8 + 4
Evaluate the like terms in the above equation
So, we have
4x = 12
Divide both sides by 4
x = 3
Hence, the value of x such that the equations are equal is 3

What is meant by the term combination?A combination is an arithmetical technique for determining the number of different arrangements in a set of items in which the order of a selection is irrelevant. You can choose the items in any order in combinations. Permutations and combinations are often confused.We will employ the formula ⁿCₓ = n! / x! * (n - x)! to calculate combinations, where n is the total number of items and x represents the amount of items chosen at a time.For the given question;
The total number of person in the pool = 11.
The number of jury selected = 3.
Thus, the combination will be ⁿCₓ.
Where, n = 11 and x = 3.
¹¹C₃ = 11!/3!(11 - 3)!

What is unitary method?This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.
How to Apply the Unitary Method
Let's first list the data that we currently have. The number of ice creams is 5. It costs $125 for 5 ice creams.
step 1:Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.
Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.
Given:
Cots of 1 liter jar of Mayonnaise (I) = 2.45
Cost of 2 liter jar of Mayonnaise (II)=4.75
Cots of 1 liter jar of Mayonnaise (II)= 4.75/2= 2.375
If she eats half liter Mayonnaise in a day
So, she eat in 14 days = 0.5 x 14 = 7 liter
Hence, Mayonnaise cost of £4.75 for a 2 liter jar lowest price Eleanor can buy.

The graph of the derivative of a function f crosses the x-axis 3 times. What does this tell you about the graph of f ?
Answer:
D. The function f has 3 horizontal tangent lines
Step-by-step explanation:
Well whenever any function crosses the x-axis, it means that the y-value is equal to zero.
In this case when the derivative passes the x-axis it indicates the tangent line corresponding to that x-value has a slope of zero, which when plotted is a horizontal line.
This means that the graph f has 3 horizontal tangent lines.
