Answer:
"490 grams" would be the correct solution.
Step-by-step explanation:
The given values are:
Half time,
T = 35 days
Total time,
t = 105 days
As we know,
⇒ [tex]A=A_o(\frac{1}{2} )^{\frac{t}{T} }[/tex]
On substituting the values, we get
⇒ [tex]=3920\times (\frac{1}{2})^{\frac{105}{35} }[/tex]
⇒ [tex]=3920\times (0.5)^3[/tex]
⇒ [tex]=3920\times 0.125[/tex]
⇒ [tex]=490 \ grams[/tex]

The function shown the the graph is f(x) =
Options
x^4-2x^2+5x+6
x^3-2x^2-5x+6
x^3-2x^2+5x+6
-x^4-2x^2+5x+6
pls help asap,,
Answer:
B
Step-by-step explanation:
We will first look at the end behavior of the graph
Is it down then up which means that the degree is 3 and the coeficcent is positive
this leaves B or C
We then know that the x intercepts are (-2,0) (1,0) (3,0)
The easiest way to proceed from here is just plugging in numbers into our euqation and if the end result is 0 then we got it!
looking at the B we have
-2³-2*-2²-5(-2)+6
this equals 0 which means this is our answer (this elimates C because the only difference between the two equations is the sign on the 5x)
You can also factor it and find the zeroes that way, but it's just more work
The black line is the graph of y=x. Which of these equations could represent the blue line?
A. y=2x

1.x^2+12x+32
2.2x^2+10x+12
3.2^2+12x+16

Suppose you are going to draw two cards from a standard deck. What is the probability that the first card is an even card and the second card is Queen? 16/663 5/169 06/13 20/663
Answer:
I would say 16/663 but I still have a suspicion it may be 20/663
Step-by-step explanation:
Answer:
20/633
Step-by-step explanation:
The probability of drawing an even card is the total number of even cards divided by the total number of cards. There are 5 even values (2,4,6,8,10) and 4 of each in the deck. That means there are 20 even cards in a deck of 52 cards. The probability is 20/52.
Next, the probability of drawing a Queen is calculated, but now there are only 51 cards total because you removed the first card. There are 4 Queens in a deck of 51 cards. The probability is 4/51.
Therefore, the probability of these two events is the product of the probability of each: (20/52)(4/51) = 20/663

Answer:
B) -1/2
Step-by-step explanation:
(2, 3) and (4, 2)
Slope:
m=(y2-y1)/(x2-x1)
m=(2-3)/(4-2)
m= (-1)/2
m= -1/2
The Slope of the given line is -1/2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
We take two points from the graph as (2, 3) and (4, 2).
Now, the slope of line is
= (3-2)/ (4-2)
= -1 / 2
= -0.5
Using Slope intercept form
y= mx+ b
y= -0.5x+ b
and, b = 4
so, the Equation of line is y= -0.5x+ 4.

What does the 3 on 4 represents?
First, we plot the dot plot.
See attachment for plot
The dots represent the number of student
So 3 dots on 4 means that:
[tex]Students \to 3[/tex]
[tex]Pairs \to 4[/tex]
This implies that there are 3 students have exactly 4 pairs
Answer:
D) There are exactly 3 students with 4 pairs of shoes.
Step-by-step explanation:
It says number of pairs on the bottom which means how many and 1, 2, 3, 4, 5 are the pairs of shoes.
At the top it says Students' pairs of shoes which is the dots and that means how many students have that amount.

write a quadratic function in the given form whose graph satisfies the given condition.
has a vertex of (5, -2) & passes through the point (3, 6) in vertex form
pls help...important...dont steal
Answer:
f(x) = 2(x-5)²-2
Step-by-step explanation:
The equation of a parabola in vertex form is y=a(x-h)²+k where (h,k) is the vertex and "a" represents how stretched or compressed the parabola is and what direction it travels.
Given a vertex of (5,-2) the equation so far is y=a(x-5)²-2
Since we want the parabola to pass through the point (3,6) we must find a value of "a" that satisfies this:
y=a(x-5)²-2
6=a(3-5)²-2
6=a(-2)²-2
6=4a-2
8=4a
2=a
This means that the quadratic function is f(x) = 2(x-5)²-2
