The resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.
What is transformation of a function?Transformation of a function is shifting the function from its original place in the graph.
Types of transformation-
Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.The given function is,
[tex]f(x) = x^2[/tex]
It has to be translated left 5 units. For this we have to add 5 units in the above function. Thus the function become,
[tex]f(x) = (x+5)^2[/tex]
Now the function is translated down 1 unit. For this we have to substract 1 units outside of the above function. Thus the function become,
[tex]f(x) = (x+5)^2-1[/tex]
Hence, the resultant function of the parent function f(x) = x², which is translate left 5 units and down 1 unit, is f(x) = (x+5)^2-1.

If mVQ=(y+7), mQR=(x+11), mRS=(3y),and mST=65,findthevaluesofxandy
Answer:
The values of x and y are x = 25 and y = 18
Step-by-step explanation:
The measure of an arc is equal to the measure of the central angle subtended by it
In circle W
∵ W is the center of the circle
∵ m∠QWS = 90°
∵ ∠QWS is subtended by arc QS
- Use the rule above
∴ m∠QWS = m arc QS
∴ m arc QS = 90°
∵ m arc QS = m arc QR + m arc RS
∵ m arc QR = (x + 11)°
∵ m arc RS = (3y)°
- Add them and equate the answer by 90
∴ (x + 11) + (3y) = 90
- Subtract 11 from both sides
∴ x + 3y = 79 ⇒ (1)
∵ VT passes through W
∴ VT is a diameter in circle W
- Diameter divides the circle into two equal arcs the measure
of its arc is 180° because the measure of the circle is 360°
∴ m arc VQRST is 180°
∵ m arc QRS = 90°
∵ m arc VQRST = m arc VQ + m arc QRS + m arc ST
- Substitute the measures of arc VQRST and QRS
∴ 180 = m arc VQ + 90 + m arc ST
- Subtract 90 from both sides
∴ 90 = m arc VQ + m arc ST
∵ m arc VQ = (y + 7)°
∵ m arc ST = 65°
∴ 90 = (y + 7) + 65
- Add like terms in the right hand side
∴ 90 = y + 72
- Subtract 72 from both sides
∴ 18 = y
Substitute the value of y in equation (1) to find x
∵ x + 3(18) = 79
∴ x + 54 = 79
- Subtract 54 from both sides
∴ x = 25
The values of x and y are x = 25 and y = 18
Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual values.
What are the values of a and b?
a = 0.4 and b = –0.15
a = –0.4 and b = 0.15
a = 8.6 and b = 14.25
a = –8.6 and b = –14.25
[tex]a=4.1-4.5=-0.4\\b=7.2-7.05=0.15[/tex]
The values of a and b are,
⇒ a = -0.4 and b = 0.15
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, Residual value is the difference between the observed value of the dependent variable (y) and the predicted value (ŷ) in a data set.
i.e. Residual value = given value - predicted value
From the table, the residual value corresponding to a has 4.1 as the given value and 4.5 as the predicted value.
Therefore, We get;
a = 4.1 - 4.5
a = -0.4
Similarly, the residual value corresponding to b has 7.2 as the given value and 7.05 as the predicted value.
Therefore, We get;
b = 7.2 - 7.05
b = 0.15
Therefore, a = -0.4 and b = 0.15

Which equation describes the circle having center point (3,5) and radius r = 2
in standard form?
Answer:
x^2 + y^2 - 6x - 10y + 30 = 0.
Step-by-step explanation:
In factor form the general equation is:
(x - h)^2 + (y - k)^2 = r^2 where (h, k) is the centre and r = the radius.
So here we have:
(x - 3)^2 + (y - 5)^2 = 4.
Converting to Standard Form:
= x^2 - 6x + 9 + y^2 - 10y + 25 = 4
x^2 + y^2 - 6x - 10y + 9 + 25 - 4 = 0
x^2 + y^2 - 6x - 10y + 30 = 0.
Damari needs to paint the circular concrete mural at the park. The mural has a diameter of 45 feet. A gallon of paint covers approximately 300 square feet. Each gallon is $18.99. How much will Damari spend in order to paint the mural? Use 3.14 to approximate π .
Answer:
$100.647
Step-by-step explanation:
Diameter = 45ft
Radius = diameter / 2 = 45 / 2 = 22.5ft.
1 gallon of paint covers 300ft²
1 gallon cost $18.99
The total area of the mural = πr² (since it's circular and area of a circle = πr²)
Area = πr²
Area = 3.14 * (22.5)²
Area = 1589.625ft²
The total area of the mural = 1589.625ft²
1 gallon of paint covers 300ft²
X gallons of paint will cover 1589.625ft²
Making x the subject by cross multiplying
X = (1 * 1589.625) / 300
X = 5.29875 gallons.
5.3 gallons will be required to paint 1589.625ft²
But 1 gallon costs = $18.99
5.3 gallons will cost $ y
y = (5.3 * 18.99) / 1
y = $100.647
Damari will spend $100.647 to paint the mural.

Seth solved a quadratic equation. His work is shown below, with Step 3 missing.
What could Seth have written as the result from Step 3?
+ (x 1)2 + 5 = 23
5(x - 1)2 = 18
Step 1
(x - 1)2 = 36
Step 2
Step 3
x = -5 or = 7
Step 4
Answer:
|x - 1| = 6
Step-by-step explanation:
After step 2, we have that:
(x - 1)^2 = 36
and after step 4, we have the results:
x = -5 or x = 7
After step 2, what we can do in step 3 is: use square root in both sides of the equation:
|x - 1| = 6
This equation can be split in two:
x - 1 = 6 -> x = 7
x - 1 = -6 -> x = -5
So Seth could write this equation in step 3:
|x - 1| = 6
The value of x from the given expression are 5 and 7
Solving expression for the variableGiven the expression
5(x - 1)^2 = 18
Step 2 as shown is given as:
(x - 1)^2 = 36
Take the square root of both sides
√(x - 1)^2 = √36
x - 1 = 6
The solutions are x - 1 = 6 and x + 1 = 6
x = 6 + 1 = 7
x = 6 - 1
x = 5
Hence the value of x from the given expression are 5 and 7

If x = 48 cm and y = 55 cm, what is the length of w?
A. 77 cm
B. 37 cm
c. 103 cm
D. 73 cm
The length of 'w' is approximately 73 cm.
Explanation:To find the length of 'w,' we can use the Pythagorean Theorem since 'w' is the hypotenuse of a right triangle with legs 'x' and 'y.' The Pythagorean Theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs. So, we have:
w^2 = x^2 + y^2
Substituting the given values, we get:
w^2 = 48^2 + 55^2
w^2 = 2304 + 3025
w^2 = 5329
Taking the square root of both sides, we find:
w = √5329
w ≈ 73 cm
Final answer:
After performing the calculations, the hypotenuse w is found to be 73 cm, which corresponds to option D.
Explanation:
To find the length of w, which is the hypotenuse of the right-angled triangle with sides x = 48 cm and y = 55 cm, we use the Pythagorean theorem.
This theorem states that in a right triangle, the square of the length of the hypotenuse (w) is equal to the sum of the squares of the lengths of the other two sides (x and y).
According to the theorem:
w² = x² + y²
Plugging in the given values:
w² = 482 + 552
w² = 2304 + 3025
w² = 5329
To find w, we take the square root of both sides:
w = √5329
w = 73 cm
Therefore, the length of w is 73 cm, which corresponds to option D.

dan made $242 for 11 hours of work. At the same rate , how many hours would he have to work to make $ 154
Answer: 7 hours to make $154.
Step-by-step explanation: First we want to know how much Dan makes in 1 hour of work. To do this simply divide 242 by 11. 242/11 = 22, or $22 per hour of work.
T find how many hours he would have to work to make $154, simply divide 154 by 22. 154/22 = 7, or 7 hours of work.
So, Dan will have to work 7 hours to make $154.
Final answer:
Dan earns $22 per hour, so to make $154, he would need to work for 7 hours at that same rate.
Explanation:
Dan made $242 for 11 hours of work. To calculate the rate of pay per hour, we would divide $242 by 11 hours, which gives us a rate of $22 per hour. The question asks how many hours Dan would need to work to make $154 at the same rate. To find this, we divide $154 by the hourly rate of $22.
$154 ÷ $22 per hour = 7 hours
Therefore, Dan would have to work for 7 hours to make $154 at the same rate of pay.
jennifer walks 8 miles in the same time she can jog 13 miles. if her jogging speed is 8mph faster than her walking speed, how fast does she walk?
Answer:
12.8mph
Step-by-step explanation:
Let 'w' represent her walking speed
->if her jogging speed is 8mph faster than her walking speed
Jogging speed= w+8
Using the time equation i.e time = dist/speed
For walking when distance is 8miles
time = dist / speed= 8/w hrs
For jogging when distance is 13miles
time = dist / speed= 13/(w+8) hrs
Equating the time
jog time = walk time
13/(w+8) = 8/w
By cross multiplying it
13w = 8w + 64
5w = 64
w=64/5
w=12.8mph
Therefore, 12.8mph is her walking speed.
