55+1200+300=1555
Answer:
Step-by-step explanation:
start by graphing it (see picture)
formula for a parabola: y=ax²
using the coordinates (600,55) we get
55=a*600²
a=55/(600²)
so now it's just a matter of plugging in 300 for x
(55/600²)*300²= 13.75

Determine f –1(x) if f of x is equal to the quantity x plus 3 end quantity over the quantity x minus 4 end quantity where x 4.
f inverse of x is equal to the quantity x minus 1 end quantity over the quantity 4 times x plus 3 end quantity
f inverse of x is equal to the quantity 4 times x plus 3 end quantity over the quantity x minus 1 end quantity
f inverse of x is equal to the quantity x minus 4 end quantity over the quantity x plus 3 end quantity
f inverse of x is equal to the quantity x minus 3 end quantity over the quantity x plus 4 end quantity
Answer:
Option BStep-by-step explanation:
Given function:
f(x) = (x + 3)/(x - 4)Find its inverse, take f(x) as y and swap x with y
x = (y + 3)/(y - 4)x = (y - 4 + 7) / (y - 4)x = 1 + 7/(y - 4)x - 1 = 7 / (y - 4)y - 4 = 7 / (x - 1)y = 4 + 7 / (x - 1)y = (4x - 4 + 7)/ (x - 1)y = (4x + 3) / (x - 1)Replace y with f⁻¹(x):
f⁻¹(x) = (4x + 3) / (x - 1)Correct choice is B
A x is equal to the quantity x plus 3 end quantity over the quantity x minus 4 end quantity where x 4. at x = 0.5, the inverse function f²(-1)(x) f²(-1)(x) = 0.5
To determine the inverse of the function f(x) = (x + 3) / (x - 4), to follow these steps:
Replace f(x) with -1, since you're looking for the inverse at the point where f(x) = -1:
-1 = (x + 3) / (x - 4)
Solve for x in terms of -1:
Multiply both sides by (x - 4):
-1 ×(x - 4) = x + 3
Distribute the -1:
-x + 4 = x + 3
Solve for x:
Subtract x from both sides:
4 = 2x + 3
Subtract 3 from both sides:
1 = 2x
Divide by 2:
x = 0.5

Answer:
68. (-1, 0)
69. (0, 2)
70. (2, -1)
Step-by-step explanation:
The solution is the ordered pair (x, y) where the lines intersect. The graphs have no scale, so we must assume 1 grid space corresponds to 1 unit.
The first coordinate of the pair is the horizontal distance from the y-axis. Positive is to the right. The second coordinate of the pair is the vertical distance from the x-axis. Positive is up.
68. The point of intersection is 2 left of the origin on the x-axis. x=-2, y = 0.
(x, y) = (-2, 0)
__
69. The point of intersection is 2 up from the origin on the y-axis: y = 2, x = 0.
(x, y) = (0, 2)
__
70. The point of intersection is 2 right and 1 down from the origin: x = 2, y = -1.
(x, y) = (2, -1)

Write the equation of the line that passes through the points (8,3) and (7,3). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line
Step-by-step explanation:
the equation :
(y-3)/(3-3) = (x-8) /(7-8)
(y-3) /0 = (x-8) /(-1)
(-1)(y-3) = 0(x-8)
-y +3 = 0
y = 3
(this is a horizontal line)
Answer:
y = 3 (Horizontal line)
Step-by-step explanation:
point: (8, 3) and (7, 3)
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 3)/(3 - 3) = (x - 8)/(7 - 8)
(y - 3)/0 = (x - 8)/(-1)
(-1)(y - 3) = 0
-y + 3 = 0
-y = - 3
y = 3 (Horizontal line)

Find the area of the shaded region. Round your answer to the nearest hundredth.
12=side length
The area of the shaded region is about — square units.
How do you find the area of the shaded region? Thank you!
Answer:
Step-by-step explanation:
Divide 360 by the number of sides in a regular polygon to find θ
θ = 360/5 = 72°
Use law of cosines to find the radius of the circle which equals the common length sides of the isosceles triangle
12² = R² + R² - 2•R•Rcos72
12² = 2R² - 2R²cos72
12² = 2R²(1 - cos72)
R² = 12² / 2(1 - cos72)
R² = 104.1993788...
R = 10.2078...
The height of the isosceles triangle is
h = Rcos(θ/2) = 10.2078cos(72/2) = 8.258291...
The shaded area is the area of the circle minus the area of the pentagon.
A = π(104.1993) - 5(½(12)(8.258291))
A = 327.35200... - 247.74874...
A = 79.6032575...
A = 79.60 units²
The Area of the shaded region is A = 79.60 units²
What is law of Cosine?A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle that separates them by two.
Given:
length= 12
So, Divide 360 by the number of sides in a regular polygon
θ = 360/5
θ = 72°
Use law of cosines
12² = R² + R² - 2 x R x Rcos72
12² = 2R² - 2R² cos72
12² = 2R²(1 - cos72)
R² = 12² / 2(1 - cos72)
R² = 104.1993788...
R = 10.2078...
Thus, the height of the isosceles triangle is
h = R cos(θ/2)
= 10.2078cos(72/2)
= 8.258291...
and, the shaded area is
A = π(104.1993) - 5(½)(12)(8.258291))
A = 327.35200 - 247.74874
A = 79.6032575
A = 79.60 units²

If your income is constant, what will happen to your savings when your expenses increase?
PASAGOT PO!!!!!
Okay, suppose your income is about $100.
You might spend $70 & save $30.
Now, suppose your income remains constant at $100 but your expenses go up to, say, $90. You can see that your savings will reduce or decrease. Now, you'll only have about $10 to save.
=》 So, if your income is constant, then your savings will 'decrease' when your expenses increase.
