Answer:
x=0 or x=−95
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−190x=2x²
Step 2: Subtract 2x² from both sides.
−190x−2x²=2x²−2x²
−2x²−190x=0
Step 3: Factor left side of equation.
(−2x)(x+95)=0
Step 4: Set factors equal to 0.
−2x=0 or x+95=0
x=0 or x=−95
[tex]~~~~2x^2 =-10 \times 19\\\\\implies 2x^2 = -190\\\\\implies x^2 = -\dfrac{190}2\\\\\implies x^2 = -95\\\\\implies x = \pm\sqrt{-95}\\\\\implies x = \pm \sqrt{-1}\sqrt{95}\\\\\implies x = \pm i\sqrt{95}[/tex]

The half life of radium is 1690 years. if 80 grams are present now, how much will be present in 830 years
Answers
Answer:
A(t) = amount remaining in t years
= A0ekt, where A0 is the initial amount and k is a constant to be determined.
Since A(1690) = (1/2)A0 and A0 = 80,
we have 40 = 80e1690k
1/2 = e1690k
ln(1/2) = 1690k
k = -0.0004
So, A(t) = 80e-0.0004t
Therefore, A(430) = 80e-0.0004(430)
= 80e-0.172

Thaddeus wants to cover an area around a pond with natural slate stone. If the cost of the slate is $6.50 per square foot, how much will it cost to surround the pond?
Answers
Answer:
Cost of slate path using π: $980.18 (nearest cent)
Cost of slate path using π = 3.14: $979.68
Step-by-step explanation:
Formula
Area of a circle = πr² (where r is the radius)
First, calculate the area of the slate path by subtracting the area of the pond from the area of the larger circle.
Area of larger circle = π · 8² = 64π ft²
Area of pond (smaller circle) = π · 4² = 16π ft²
⇒ area of slate path = 64π - 16π = 48π ft²
If the cost of the slate is $6.50 per ft² then,
Cost of slate path using π:
⇒ 48π × $6.50 = $980.18 (nearest cent)
Cost of slate path using π = 3.14:
⇒ 48 × 3.14 × $6.50 = $979.68

Coordinate of a functionThe coordinate of a function are written in the form (x, y)
Given the amount of money Emily spends, after r rides, at a carnival
is modeled by the function y = 8r + 20
We are to determine the coordinate that satisfies the function
For the coordinate (15, 140)
If r = 15, then
y = 15(8) + 20
y = 140
Hence the coordinate (15, 140) satisfy the function
For the coordinate (11, 108)
If r = 11, then
y = 11(8) + 20
y = 108
Hence the coordinate (11, 108) satisfy the function
