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 one on the right is a proportional relationship between x and y
Step-by-step explanation:
Your going to have the divide y by x so (y ÷ x)
5÷2 = 2.5
10÷4 = 2.5
15÷6 = 2.5
They all end up having the same answer. So when you divide y by x, you have to have the same answer for every single one.

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
≈ 67.4 g

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

[tex]y = -\frac{3}{4}x-\frac{3}{2}[/tex]
Step-by-step explanation:
First, calculate the slope of the line:
[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{(-6) - 3}{6 - (-6)}\\m = \frac{-9}{12}\\m = \frac{-3}{4}[/tex]
Next, calculate the y-intercept:
Choose any point on the line.
[tex](-6,3)[/tex]
Solve for [tex]b[/tex].
[tex]y = mx + b\\b = y - (mx)\\b = 3 - (\frac{-3}{4} * -6)\\b = 3 - \frac{9}{2}\\b = \frac{-3}{2}[/tex]
Finally, create the equation:
[tex]y = -\frac{3}{4}x-\frac{3}{2}[/tex]
