A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)^x. To the nearest hundredth, how much sodium-24 can the scientist predict will remain 12 hours after the experiment started?
_mg
Answer:
56.43
Step-by-step explanation:
The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)ˣ.
The amount of the sodium-24 that scientists can predict will remain 12 hours after the experiment started will be given as,
y = 98.8 (0.9544)¹²
y = 98.8 (0.571169)
y = 56.43 mg
The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.

We were just learning these :)
Step-by-step explanation:
So let's start with the whole equation:
10 - 4x + 6 - 2x = -2x
First, combine like terms:
16 - 6x = -2x
Next, add 16 to both sides:
16 + 16 = cancels out and -2x + 16 = 14
6x = -2x
Now, divide 6 on both sides:
6 / 6 = cancels out and -2x / 6 = -.3
x = -.3

What is the slope of this function?
slope = (y2-y1)/(x1-x2)
=(20-8)/(2-1)
=12/1
m = 12
The slope of the given function is 12.
Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
In this case, we are given three points:
Point 1: (x = 1, y = 8)
Point 2: (x = 2, y = 20)
Point 3: (x = 3, y = 32)
The slope of the function is calculated by the formula given as;
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope =(20-8)/(2-1)
=12/1
Slope = 12
The slope is 12.

HELLLLPPPPP !!!!!!!! I don't get what we are learning so can someone plz do this and explain it (if you can/want) simplify 3x+15y=45
Answer: x=10
Step-by-step explanation:
Simplifying
3x + 15 = 45
Reorder the terms:
15 + 3x = 45
Solving
15 + 3x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 3x = 45 + -15
Combine like terms: 15 + -15 = 0
0 + 3x = 45 + -15
3x = 45 + -15
Combine like terms: 45 + -15 = 30
3x = 30
Divide each side by '3'.
x = 10
Simplifying
x = 10

A. 6
B.-6
C.-4
D. 4
PLEASE EXPLAIN
Your question is incomplete, here is the complete form.
Points J, K and L are collinear with J between L and K. If KJ = 2x - 3, LK = 9x + 7 and LJ = 4x - 8, solve for x:
Answer:
The value of x is -6 ⇒ B
Step-by-step explanation:
∵ J, K, and L are collinear
→ That means they form a straight segment
∵ J is between K and L
→ That means J divides LK into two segments KJ and LJ
∴ LK = KJ + LJ
∵ LK = 9x + 7
∵ KJ = 2x - 3
∵ LJ = 4x - 8
→ Substitute them in the equation above
∴ 9x + 7 = (2x - 3) + (4x - 8)
→ Add the like terms in the right side
∵ 9x + 7 = (2x + 4x) + (-3 - 8)
∴ 9x + 7 = 6x + -11
∴ 9x + 7 = 6x - 11
→ Subtract 7 from both sides
∵ 9x + 7 - 7 = 6x - 11 - 7
∴ 9x = 6x - 18
→ Subtract 6x from both sides
∵ 9x - 6x = 6x - 6x - 18
∴ 3x = -18
→ Divide both sides by 3
∵ [tex]\frac{3x}{3}=\frac{-18}{3}[/tex]
∴ x = -6
∴ The value of x is -6
The value of x for the given problem comes to be -6.
KJ = 2x-3
LJ= 4x-8
LK = 9x+7
What are collinear points?Points that are part of a straight line are called collinear points.
Points J, K, and L are collinear so they will be in a straight line.
So, KJ + LJ = LK
(2x-3) + (4x-8) = (9x +7)
6x - 11 = 9x + 7
-3x = 18
x= -6
Therefore, the value of x for the given problem comes to be -6.
