Answer:
Step-by-step explanation:
The center tells you how to handle the left side of a circle's equation.
(x - 2)^2 + (x - 1)^2 = r^2
The point (5,2) gives you enough information to find r^2
x = 5
y = 2
(5 - 2)^2 + (2 - 1)^2 = r^2
(3)^2 + 1^2 = r^2
9 + 1 = r^2
r^2 = 10
Complete equation
(x - 2)^2 + (y - 1)^2 = 10
Answer: (x-2)^2+(y-1)^2=10
Step-by-step explanation:
r=√(x-h)^2+(y-k)^2
r=√(5-2)^2+(2-1)^2
r=√3^2+1^2
r=√9+1
r=√10
X^2+y^2=r^2
(x-2)^2+(y-1)^2=(√10)^2
(x-2)^2+(y-1)^2=10

given that (6,-3) is on the graph of f(x), find the corresponding point for the function f(1/3x)
Answer:
The corresponding point for the function [tex]f(\frac{1}{3}x)[/tex] is
(18, -3)
Step-by-step explanation:
By definition if we have a function f(x) and we apply the transformation:
[tex]y = f (hx)[/tex]
Then:
If [tex]0 <h <1[/tex] the graph is stretched horizontally by a factor [tex]\frac{1}{h}[/tex]
If [tex]h> 1[/tex] the graph is compressed horizontally by a factor [tex]\frac{1}{h}[/tex]
In this case [tex]h=\frac{1}{3}[/tex] this is [tex]0 <h <1[/tex] then the graph is stretched horizontally by a factor [tex]\frac{1}{\frac{1}{3}}=3[/tex]
Therefore the point (6, -3) that belongs to f(x), in the transformed function will be (3*6, -3) This is (18, -3)

Marissa Palmer’s charge account statement showed a previous balance of $142.55, a finance charge of $2.82, new purchases of $86.50, and a payment of $80.00. What is her new balance?
Answer:
$151.87
Step-by-step explanation:
The new balance includes the previous balance, plus finance/interests charges, plus the new purchases, minus the payment(s).
So,
Previous balance: $142.55
+ Finance charge: $2.82
+ New purchases: $86.50
= Sub-total: $231.87
- Payment: $80.00
= New Balance: $151.87
Marissa Palmer's new balance after considering her previous balance, finance charge, new purchases, and payment is $151.87.
Explanation:To calculate Marissa Palmer's new balance on her charge account statement, we need to consider several components: the previous balance, finance charge, new purchases, and the payment she made. We start with her previous balance, add any finance charges, add the cost of new purchases, and then subtract any payments. Here's the step-by-step calculation:
Start with the previous balance of $142.55.Add the finance charge of $2.82 to the previous balance, yielding $145.37.Add new purchases of $86.50 to the total, resulting in $231.87.Subtract the payment of $80.00 to find the new balance.When we do the subtraction ($231.87 - $80.00), we find that her new balance is $151.87.

Answer:
Step-by-step explanation:
So, if we know that 25 is the area of the square, that means that each side is 5. That also means the diameter of the circle is 5, so the radius is 2.5. Now, we can input the radius into the circumference formula for a circle, which is 2πradius. So, 2π2.5 which equals 5π, or about 15.71
how wide can a 5 m load be to fit under a parabolic underpass that is 7 m wide and 7 m at its highest point
Answer:
[tex]\boxed{\text{3.74 m}}[/tex]
Step-by-step explanation:
This is equivalent to finding the equation of a parabola from three points.
Let's call the ground-level points (-3.5, 0) and (3.5, 0).
The axis of symmetry will be the y-axis, so the vertex is at (0, 7).
Part 1. Find the equation of the parabola
The vertex form of the equation for a parabola is
y = a(x - h)² + k
where (h, k) is the vertex of the parabola.
If the vertex is at (0, 7),
h = 0 and k = 7
The equation is
y = ax² + 7
Insert the point (0, -3.5)
0 = a(0 + 3.5)² + 7
0 = a(3.5)² + 7
0 = 12.25a + 7
-7 = 12.25a
a = -0.5714
The equation in vertex form is
y = -0.5714x² + 7
Part 2. Calculate the width when y = 5
5 = -0.5714x² + 7
-2 = -0.5714x²
x² = 2/0.5714
x² = 3.5
x = ±√3.5 = ±1.87
So, on the graph, the coordinates of the truck at ground level are x = -1.87 and x = +1.87.
The maximum width of the load is 1.87 – (-1.87) =[tex]\boxed{\textbf{3.74 m}}[/tex]
In the diagram below, the red parabola represents the underpass, and the blue box is the truck going through it.

Answer:
18 cm²
Step-by-step explanation:
The area labelled A is a triangle.
The area (A) of a triangle is calculated using the formula
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
here b = 9 and h = 4 ( the same height as the rectangle ), thus
A = [tex]\frac{1}{2}[/tex] × 9 × 4 = [tex]\frac{1}{2}[/tex] × 36 = 18 cm²

How to simplify 11/3
3 2/3 the answer because....
11 cant fit into three so, if you divide 11%3 = 3 2/3 now let’s see, how much times can you multiply 3 into 11 only 3 times 3,6 and 9 (things) then the 2/3 is there because, if add 1 more 0.1 you get 12/3 but it’s not it’s 2/3 of the value
11/3 is already in its simplest fractional form as there are no common factors between 11 and 3. However, it can be expressed as a mixed number, which is 3 2/3 in this case.
Explanation:To simplify 11/3, you must first understand what it means to simplify a fraction. Simplifying a fraction means to reduce it to its simplest form, or to a form that can no longer be reduced. However, 11/3 is a fraction that cannot be simplified any further as there are no common factors between the numerator (11) and the denominator (3). It is in its simplest form. But, if we're looking to express this as a mixed number, we would divide 11 by 3. The result is 3 with a remainder of 2. Hence, 11/3 can be expressed as the mixed number 3 2/3

What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
We have:
X = 2 centimeters, Y = 4 centimeters, and Z = 7 centimeters
Here no other details have been provided, so we are assuming we have two rectangles dimensions for the first is 2×4, and for the second 4×7
Total area = 2×4 + 4×7 = 8+28 = 36 square cm

y=__x-10
3x-__y=-19
Answer:
y=-5x-10
3x-2y=-19
We can actually see here that the completed equations are:
1. y = -5x - 10
2. 3x - 2y = -19
How we arrived at the solution?To find the missing values in the equations such that the solution is (-3, 5), we substitute the values of x = -3 and y = 5 into the equations and solve for the missing values.
For the equation y = x - 10:
Substituting x = -3 and y = 5:
5 = -3 - 10
5 = -3__ - 10
5 + 10 = -3__
15 = -3__
__ = -5
Therefore, the missing value is -5. The completed equation is:
y = -5x - 10
For the equation 3x - y = -19:
Substituting x = -3 and y = 5:
3(-3) - 5 = -19
-9 - 5 = -19
-9 + 19 = 5
10 = 5__
__ = 2
Therefore, the missing value is 2. The completed equation is:
3x - 2y = -19
The completed equations are:
y = -5x - 103x - 2y = -19When x = -3 and y = 5, both equations will have a solution of (-3, 5).

the first choice is correct
The maximum area of the rectangle will be 242 square ft. The expression for a in terms of x will be 44 - 2x. Then the correct option is C.
What is a rectangle?It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
If the a, b, and x are 44 ft. Then the expression for a in terms of x will be
We know that b = x
Then we have
a + b + x = 44
a + 2x = 44
a = 44 - 2x
Then the area opf the rectangle will be
Area = (44 - 2x)x
Area = 44x - 2x²
For maximum area the value of x will be 11. Then we have
Area = 44 × 11 - 2 × 11²
Area = 242 square ft

1. (-6,8)
2. (6,8)
3. (-6,-8)
4 .(6,-8)
Answer:
3.(-6,-8)
Step-by-step explanation:
y=x-2
2x+4=y
x-2=2x+4
x=2x+6
-x=6
x=-6
y=-6-2
y=-8
Step 1: Wherever you see a y in the equation: 2x + 4 = y insert x - 2
2x + 4 = x - 2
Step 2: Combine like terms
x's go with x's. To do this subtract the x from the right side to both sides
(2x - x) + 4 = (x - x) - 2
x + 4 = 0x - 2
x + 4 = -2
Normal numbers go with normal numbers (4 and -2). Bring the 4 to the right side by subtracting it to both sides
x + (4 - 4) = -2 - 4
x + 0 = -6
x = -6
Step 3: To solve y put -6 where you see an x in the equation: y = 2x + 4
y = 2(-6) + 4
y = -12 + 4
y = -8
(-6,-8)
Hope this helped!
