Answer: 256 CAD
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the price in US dollars of the iphone (320) and multiply it by 0.80 ( Canadian dollar to US dollar exchange rate)
Mathematically speaking:
Since:
$1 US = 0.80 CAD
$320 x0.80 = 256 CAD

What is the median of the first half of the data? (first quartile)
The median of the given data is 4.5
How to find the median of data?The median of data are values in the middle after rearrangement. Since we are not given a set of data, let us use the following data
2, 3, 5, 9, 4, 5, 3, 11
Arrange the given data
2, 3, 3, 4, 5, 5, 9, 11
From the arranged data , 4 and 5 are at the middle. Take the average

AC ≈ 2.87
Step-by-step explanation:
Using the sine ratio in the right triangle
sin35° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{AC}{5}[/tex]
Multiply both sides by 5

Answer:
1). a = 9.42 m
2). b = 6.37 m
3). c = 4.48 m
Step-by-step explanation:
In the figure attached,
By applying tangent rule in triangle ADE,
tan47 = [tex]\frac{h}{c}[/tex]
c = [tex]\frac{h}{\text{tan}47}[/tex]
c = [tex]\frac{4.8}{\text{tan}47}[/tex]
c = 4.476
c ≈ 4.48 m
Now we apply the same rule in triangle ACE,
tan37° = [tex]\frac{h}{b}[/tex]
b = [tex]\frac{h}{\text{tan}37}[/tex]
b = [tex]\frac{4.8}{1.0724}[/tex]
b = 6.37 m
Now apply the tangent in triangle ABE,
tan27° = [tex]\frac{h}{a}[/tex]
a = [tex]\frac{h}{\text{tan}27}[/tex]
a = [tex]\frac{4.8}{0.5095}[/tex]
a = 9.42 m

what transformations were applied to ABCD to obtain A'B'C'D'?
Answer:
the answer is C
Step-by-step explanation:
Rotate 90 degrees counterclockwise , the translate three units to the left
Option C is the correct transformation to transform ABCD to A'B'C'D'.
What are rotation and translation?Rotation involves moving an object about a fixed point. Each point on the object describes a circular path with the center, the center of rotation.Translation involves moving an object such that only one of the three cartesian coordinates changes during the transformation.Rotation
Rotate the square ABCD counterclockwise about the origin. Sides AD and BC of square ABCD will become parallel to the sides A'D' and B'C' respectively of the square A'B'C'D'. The square ABCD is, thus, oriented the same way as the square A'B'C'D'.
Vertical Translation
After the rotation, the side AB is 1 unit above the y-axis, which is the same as that of the square A'B'C'D'. So, the vertical position of the square ABCD is the same as that of the square A'B'C'D'.
Horizontal Translation
The side AD of the square ABCD is 5 units to the left of the x-axis. The side A'D' of the square A'B'C'D' is 8 units to the left of the x-axis. So, translate the square ABCD to the left by 3 units to coincide with the position of A'B'C'D'.
Thus, to obtain A'B'C'D' from ABCD first rotate it by 90° counterclockwise then, translate it to the left by 3 units.

Answer:
$30
Step-by-step explanation:
since there is no sales tax,
Amount of money used to pay
= change + total price of items bought
Let's find the total price of the items she bought.
Chicken
1 package ----- $12.36
2 packages ----- 2($12.36)= $24.72
Broccoli
1 pound ----- $1.98
½ pound ----- $1.98 ÷2= $0.99
Milk
1 gallon ----- $3.49
Total amount paid
= $24.72 +$0.99 +$3.49
= $29.20
Thus, amount of money Susan used to pay
= $29.20 +$0.80
= $30

Find sin, where the angle is shown
Give the exact value, not a decimal approximation
Answer:
sinΘ = [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex]
The opposite is 24, but we require the hypotenuse h
Using Pythagoras' identity
h² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
h = [tex]\sqrt{625}[/tex] = 25
Thus
sinΘ = [tex]\frac{24}{25}[/tex]

The requried function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.
What is the intercept in the equation?In the equation intercept is the value of the linear function where either of the variables is zero.
Here,
The x-intercept is the point where the graph of a function intersects the x-axis. At this point, the value of y is 0. To find the x-intercept of each function, we set y equal to 0 and solve for x.
A. f(x) = 3x – 9
0 = 3x – 9
3x = 9
x = 3
B. f(x) = 1/x + 4
0 = 1/x + 4
-4 = 1/x
x = -1/4
C. f(x) = √(x+1)
0 = √(x+1)
x = -1
D. f(x) = x²
0 = x²
x = 0
Therefore, the function with the smallest x-intercept value is C. f(x) = √(x+1), which has an x-intercept of -1.

Explain how to determine the zeros of f(x)=(x+3)(x-1)
Answer:
x= -3, x = 1
Step-by-step explanation:
Zeros are values of x, when f(x) = 0.
0=(x+3)(x-1)
x+3 = 0, x - 1=0
x= -3, x = 1
Answer:
x = -3, x = 1
Step-by-step explanation:
To determine the zeroes of the factored quadratic equation, we need to look back at its definition. The zeroes are a function are specific x-values that result in a y-value of 0.
In this case, we want the numbers inside of the parantheses to equal 0. If we substitute in x = -3, we get (0)(x - 1), and we know that is just 0. Similarly, if we substitute in x = 1, we get (x + 3)(0), and we know that is just 0.
As such, these are your solutions.

Use absolute value to express the distance between −10 and 16 on the number line.
Answer: 26
Step-by-step explanation:
From -10 to 0 will be 10
1 to 16 are 16
Answer:
Step-by-step explanation:
There are several things you need to know in order to write the absolute value equation for a situation. First is how to formulate what you need. The absolute value equation follows the formatting:
| x - midpoint | = the distance between the midpoint and one of the endpoints.
That means we also need to be able to find the midpoint of -10 and 16. Finding the midpoint is finding the middle, which is the same as finding an average of the 2 numbers.
[tex]M=\frac{-10+16}{2}=3[/tex]
So the midpoint is 3. The distance between 3 and either one of the endpoints is going to be the same, by definition of the midpoint of the 2 numbers. The distance between 3 and 16 is 13 units. The distance between 3 and -10 is also 13 units. So, to put this into an absolute value equation,
| x - 3 | = 13
[10 points] Find the number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order.
Answer: The number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .
Step-by-step explanation:
Given word = "EQUATION"
Total letters = 8
Total Vowels (EUAIO)=5
Total number of ways to arrage letters = 8!
Number of ways to arrange vowels in alphabetical order = 5!
Then, The number of ways that all the vowels are in alphabetical order will be :
[tex]\dfrac{8!}{5!}=\dfrac{8\times7\times6\times5!}{5!}=336[/tex]
Hence, the number of ways of arranging the letters of EQUATION, so that all the vowels are in alphabetical order = 336 .
The softball in the mitt is 5.2 inches in diameter. What is its volume?
Answer: 72.9 in^3
Step-by-step explanation:
The softball is a sphere, and we know that the volume of a sphere is:
V = (4/3)*pi*r^3
where pi = 3.14 and r is the radius.
We also know that the radius is half the diameter, and the diameter is 5.2 in
r = 5.2in/2 = 2.6in
Then the volume is:
V = (4/3)*pi*(2.6in)^3 = 72.9 in^3
The correct answer is 73.6 in^3
