D
1.00
С
0.80
Answer:
.2 chance of going to the right store
Step-by-step explanation:
Five stores, and she is to meet a friend at one. One store is the right one so it is 1 out of 5, or 1/5. This equals 20%
In decimal it is a .2 chance of Nadine going to the right store

Find the 4th term of the expansion of (a - sqrt(2)) ^ 8
Answer:
Applying the binomial theorem
[tex]{\displaystyle (x+a)^{n}=\sum _{k=0}^{n}{n \choose k}x^{n-k}a^{k}}[/tex]
Here we have x = -[tex]\sqrt{2}[/tex], n = 8,
=> 4th term (k = 3) would be:
[tex]{8 \choose 3}x^{8-3}a^{3}} = {8 \choose 3}(-\sqrt{2})^{5}a^{3}} = -224a^{3}\sqrt{2}[/tex]

The measure of a central angle is 3 x + 18, and the measure of its arc is 147°. Which equation can you use to find the value of x ?
A) 2(3 x + 18) = 147°
B) 3 x + 18 = 2(147°)
C) 3 x + 18 = 147°
Answer:
C
Step-by-step explanation:
The central angle is equal to the measure of the arc that subtends it, thus
3x + 18 = 147 → C
Answer: C.) 3x + 18=147

Hugo reflects a vector v across the line y = –x. Nemo rotates a vector v 180° counterclockwise about the origin. Which of the following vectors would have the same image for Hugo and Nemo?
Answer:
The (3, 3) one
Step-by-step explanation:
i did the exam and got it right ;)
The vectors that have the same image for Hugo and Nemo are [3, 3].
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find the reflection of a vector v across the line y = -x, we can use the formula:
reflection(v) = R×v × R
where R is the reflection matrix given by:
R = [0 1]
[1 0]
To find the rotation of a vector v by 180° counterclockwise about the origin, we can use the formula:
rotation(v) = Rθ × v
where Rθ is the rotation matrix given by:
Rθ = [-1 0]
[0 -1]
Let's apply these transformations to each vector and see which ones have the same image for both Hugo and Nemo:
Reflection(d) = R × d × R = [0 1] × [3, 3] × [0 1] = [3, 3]
Rotation(d) = Rθ × d = [-3, -3]
These two vectors are equal.
Therefore, the vectors that have the same image for Hugo and Nemo are [3, 3].

2 horizontal and parallel lines are intersected by 2 diagonal lines to form a triangle with exterior angles. The top angle of the triangle is (2 x + 10) degrees. The bottom right angle of the triangle is 79 degrees. The exterior angle to the bottom left angle is (6 x + 1) degrees. What is the value of x? x = 2.25 x = 11.25 x = 13 x = 22
Answer:
11.25
Step-by-step explanation:
8x+11=180-79
8x+11=101
8x=90
x=11.25
By angle sum property the value of x in the expression (2 x + 10) + (6 x + 1) +79 =180 is 11.25
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
2 horizontal and parallel lines are intersected by 2 diagonal lines to form a triangle with exterior angles.
The top angle of the triangle is (2 x + 10) degrees. The bottom right angle of the triangle is 79 degrees.
The exterior angle to the bottom left angle is (6 x + 1) degrees.
By angle sum property
(2 x + 10) + (6 x + 1) +79 =180
8x+11 + 79 =180
8x+11=180-79
8x+11 =101
8x = 90
x = 11.25

Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm

a. Reflection
b. Translation
c. Dilation
d. Rotation
Answer:
translation...........
Answer:
Dilation
Step-by-step explanation:
A dilation is a type of transformation that changes the size of the image. The scale factor measures how much larger or smaller the image is.
In this example, ΔABC is dilated as seen in the picture because it the picture itself got bigger.
The image, ΔADE is now a dilated version of the pre-image ΔABC

GCF for last two terms is 2
Step-by-step explanation: GCF means the largest number that the terms can be divided by evenly.
7 and 14 are both divisible by 7. The factors of those terms are (7r^2)(r +2).
r^3 means r × r × r. r^2 means r × r so r^2 is a factor of r^3
2r and 4 are both divisible by 2. The factors of those terms are (2)(r +2)

a
$2,627.56
c. $1,627.56
b. $1,467.56
d. $1,212.89
Answer:
The answer is is
C. $1,627.56
Step-by-step explanation:
The question is incomplete,
Kindly find attached the diagram of the poll for the dimension for your reference.
we need to first calculate the area of the pool.
Let's begin by calculating the area of the rectangular shape
A= length x width
A= 25*15
A=375ft²
Secondly the two semi circles can be solved for as a whole circle
Area of circle = πr²
Radius r= diameter/2= 15/2= 7.5ft
Area = 3.142*7.5²
A= 3.142*56.25
A= 176.7375ft²
Total surface area pool =
176.7375+375= 551.7ft²
Given that a square foot is $2.95
Hence the cost of covering the pool is 551.7*2.95=$1,627.515
