The point W is plotted on the coordinate grid below. Plot the point W’ , the reflection of W over the y-axis.
( ignore where I put a dot I just needed it to see the bottom )
PLEASE HELP ASAP
Answer:
W: (-3,5)
W': (-3,-5)
Y coordinate
Step-by-step explanation:
if you want me to explain it I can in the comments thing
In the plot the coordinates of W is (-3 , 5 ) , and the reflection will be W' (-3 , -5)
What do you mean by reflection in a graph ?
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane.
When reflecting a figure in a line or in a point, the image is congruent to the preimage.
A reflection maps every point of a figure to an image across a fixed line.
So in the plot the coordinates of W is (-3 , 5 )
and the reflection will be W' (-3 , -5)
The plot of W and W' is attached with the answer.

Answer:
25.5 = c
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
17^2 + 19 ^2 = c^2
289+361 = c^2
650 = c^2
Take the square root of each side
sqrt(650) = sqrt(c^2)
25.49509757=c
To the nearest tenth
25.5 = c
Answer:
C = 25.5
Step-by-step explanation:
17² + 19² = x²
289 + 361 = x
289 + 361 = 650
√650 = 25.495097567963924150141120545114
25.495097567963924150141120545114 ≅ 25.5

Marta is building a scale model of the Empire State building which has a rectangular base. The scale on the model is 1 inch = 35 feet. Her model is 4 inches in length and 1 inch in width. What is the actual area, in square feet, of the base of the building?
Answer: The actual area of the base of the building is 4900 square feet.
Step-by-step explanation:
We have given, the scale on the model: 1 inch = 35 feet
In model,
Length= 4 feet , Width = 1 inch
As per scale ,
Actual length = 4 x 35 feet
= 140 feet
Actual width = 35 feet
Area of base of the building = Length x width
= 140 x 35
= 4900 square feet
Hence, the actual area of the base of the building is 4900 square feet.
Use the Function f(x)=6x-1 Which equation correctly describes f(b)?
a.) f(b)=6b-1
b.)= f(b)=6bx-1
c.)f(x)=6b-1
d.) b=6x-1
Answer:
a
Step-by-step explanation:
To obtain f(b) substitute x = b into f(x) , that is
f(b) = 6(b) - 1 = 6b - 1
f(x) and f(b) are very similar. The only difference is that in every place where x is in the function, we now will plug in b. This is just like plugging in a number. For example, if our function was f(x) and we had to plug in 4, it might look something like this: f(4). Very similar, and we know how to plug that number in.
Let's do the same thing with b.
f(x) = 6x - 1
f(b) = 6b - 1
Hope this helps!! :)

Circle Q has Choose... circle P.
Answer:
(a) Circle Q is 9.4 units to the center of circle P
(b) Circle Q has a smaller radius
Step-by-step explanation:
Given
[tex]P:(x - 1)^2 + (y + 6)^2 = 9[/tex]
[tex]Q:(x + 4)^2 + (y + 14)^2 = 4[/tex]
Solving (a): The distance between both
The equation of a circle is:
[tex](x - h)^2 + (y - k)^2 = r^2[/tex]
Where
[tex]Center: (h,k)[/tex]
[tex]Radius:r[/tex]
P and Q can be rewritten as:
[tex]P:(x - 1)^2 + (y + 6)^2 = 3^2[/tex]
[tex]Q:(x + 4)^2 + (y + 14)^2 = 2^2[/tex]
So, for P:
[tex]Center = (1,-6)[/tex]
[tex]r = 3[/tex]
For Q:
[tex]Center = (-4,-14)[/tex]
[tex]r = 2[/tex]
The distance between them is:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2[/tex]
Where:
[tex]Center = (1,-6)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]Center = (-4,-14)[/tex] --- [tex](x_2,y_2)[/tex]
So:
[tex]d = \sqrt{(1 - -4)^2 + (-6 - -14)^2[/tex]
[tex]d = \sqrt{(5)^2 + (8)^2[/tex]
[tex]d = \sqrt{25 + 64[/tex]
[tex]d = \sqrt{89[/tex]
[tex]d = 9.4[/tex]
Solving (b): The radius;
In (a), we have:
[tex]r = 3[/tex] --- circle P
[tex]r = 2[/tex] --- circle Q
By comparison
[tex]2 < 3[/tex]
Hence, circle Q has a smaller radius

Overnight the temperature in Chicago was -7F but by noon it had risen to 9 degrees F. What was the temperature in Chicago that afternoon?
Answer:
2 °F
Step-by-step explanation:
Overnight temperature = -7 °F
Total Noon temperature = 9 °F
What was the temperature in Chicago that afternoon?
Temperature in Chicago that afternoon = Total Noon temperature + Overnight temperature
= 9 °F + (-7 °F)
= 9 °F - 7 °F
= 2 °F
Temperature in Chicago that afternoon = 2 °F

Need help !! Slove for c
plsss help with these 2 questions
#1.
For this problem, we can use Pythagorean Theorem (a^2 + b^2 = c^2, where a and b are the legs, and c is the hypotenuse). We are given C, the hypotenuse, and A, a leg of the triangle in this problem.
9^2 + b^2 = 41^2
81 + b^2 = 1681
b^2 = 1600
b = 40 feet
#2.
We will again use Pythagorean Theorem. We are given the height and the length of a leg in this problem.
33^2 + b^2 = 65^2
1089 + b^2 = 4225
b^2 = 3136
b = 56 inches

what is the volume of a cube if the length, width, and height are 1ft?
a)6 cubic feet
b)3 cubic feet
c)4 cubic feet
d) 1 cubic foot
Answer:
The answer is D. 1 cubic foot.
Step-by-step explanation:
To solve for the volume of a cube, use the formula V= [tex]a^{3}[/tex]. This is the formula because the volume of a cube formula equals length times width times height. Since the length, width, and height are all the same values, the simplest volume of a cube formula is [tex]a^{3}[/tex].
Next, plug in the information from the question into the formula, which will look like V= [tex]1^{3}[/tex]. Then, solve the equation, and the final answer will be 1 cubic foot.

2. One important factor in inventory control is the variance of the daily demand for a product. Management believes that demand is normally distributed with the variance equal to 250. In an experiment to test this belief about , the daily demand was recorded for 25 days. The data has been summarized as follows: xbar = 50.6 and s2 = 500 Do the data provide sufficient evidence to show that management's belief about the variance is untrue? (Use alpa=0.01 ).
Answer:
we reject H0 and conclude that management's belief about variance is untrue.
Step-by-step explanation:
H0 : σ² = 250
H1 : σ² ≠ 250
Sample size, n = 25
xbar = 50.6 ; s² = 500
α = 0.01 ;
The test statistic :
χ² = [(n - 1)s²] ÷ σ²
χ² = [(25 - 1)* 500] ÷ 250
χ² = (24 * 500) / 250
χ² = 12000 / 250
χ² = 48
The critical value:
df = n-1 ; 25 - 1 = 24
χ²(0.01/2 ; 24) = 45.559
Decison :
Reject H0 : if |χ² statistic| > critical value
Since 48 > 45.559
Hemce, we reject H0 and conclude that management's belief about variance is untrue.
