The graph shows how much insulin, in micrograms (mcg), is in a patient's body after receiving an injection. Write an equation giving the number of mcg of insulin, `m`, in the patient's body h hours after receiving the injection.
By using the first two points on the graph, we conclude that exponential equation is:
y = 200*(0.4)^t
What is the equation?We assume that the equation is an exponential decay of the form:
y = A*(r)^t
When t = 0 we have:
y = A
On the graph we can see that the initial value is 200, then A = 200, so we have:
y = 200*(r)^t
By looking at the graph we can see that:
80 = 200*(r)^1 (this is the second point graphed).
Solving for r we get:
80 = 200*(r)
80/200 = r = 0.4
Then the exponential equation is:
y = 200*(0.4)^t

Is the area of a square with side length 2 inches greater than or less than the area of a circle with radius 1.2 inches?
Answer:
less
Step-by-step explanation:
We can answer the question about relative sizes of a square and a circle by finding the area of each.
__
The area of the square is ...
A = s²
A = (2 in)² = 4 in²
The area of the circle is ...
A = πr²
A = π(1.2 in)² = 1.44π in² ≈ 4.524 in²
The area of the square is less than the area of the circle.
_____
Additional comment
The area of a circle is π/4 times the area of the square in which it is inscribed. If the diameter of the circle is 1.2 times the side length of the square, its area ratio to the square will be (1.2²)(π/4) = 0.36π ≈ 1.13. That is, the circle is larger and the square is smaller.

trigonometry Review!
Trigonometric Ratios: Find each trig ratio. Give your answer as a fraction in simplest form.
Answer:
9. Tan(57°)=~9.24 or 231/25
10. Sin(31°)= ~9.79 or ... 979/100
11. Sin(x°)= 15/23
12. Tan(x°)=37/8
Step-by-step explanation:
9. For the side length, we must use the given angle and the given side. We want to find the opposite given the adjacent side length of 6. We multiply tan(57°) by 6 using a scientific or graphing calculator and we get the answer 9.24 (after rounding) and then convert to a fraction in simplest form since it asked for a fraction. We would get 231/25
10. Just like the last question, we are given the opposite side length but not the hypotenuse. For this, we use sin. Multiply sin(31°) by 19 and we will getb 9.79 after rounding. Convert this into a fraction and we get 979/100 as the simplest form.
11. For this question we have 2 sides but not the angle. For this, we must use the SOH CAH TOA rule and just connect the pieces. We have the opposite and the hypotenuse or OH which means we have S which is sin. We then write Sin(x°)=15/23
12. For this we have the adjacent and opposite which is OA and that leaves us with T which is Tan(x°)=37/8. Remember that opposite comes before adjacent which is why it isn't 8/37. Hope this helps! (btw I'm not a bot)

A rational function that has a domain of x # 1 and x 4 and passes through
(-3, 3). Find the function.
Step-by-step explanation:
If the domain doesn't have 1 or 4 in it. This means 1 and 4 are the zeroes of the denomiator of the rational function.
So
[tex](x - 1)(x - 4)[/tex]
[tex]( {x}^{2} - 5x + 4)[/tex]
So that is the denomiator.
The numerator passes through (-3,3).
Let A represent a posible value of the numerator.
[tex]y = \frac{a}{( {x}^{2} - 5x + 4) } [/tex]
Plug in -3 for x and 3 for y.
[tex]3 = \frac{a}{ - 3 {}^{2} - 5( - 3) + 4 } [/tex]
[tex]3 = \frac{a}{9 + 15 + 4} [/tex]
[tex]3 = \frac{a}{28} [/tex]
[tex]84 = a[/tex]
So one possible function is
[tex]y = \frac{84}{ {x}^{2} - 5x + 4 } [/tex]

There are 10 pink balls out of 20. (add all the numbers together)
So that means there is a 10/20 chance to get a pink ball.
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
So, the probability is the number of favored outcomes/ number of possible outcomes.
In this case, the favored outcomes is pink, which is 10.
The number of possible outcomes is 2+1+10+2+5 = 20
This gives us 10/20, which is 1/2 when simplified

does anyone know the exponent rules
The exponent rules are given below.
We are given that;
To state exponent rules
Now,
Exponent rules are the laws or principles that govern the operations on numbers or variables with exponents. An exponent is a number or a variable that tells how many times to use the base in a multiplication.
There are different exponent rules for different situations, such as multiplying, dividing, raising to another power, or having a negative or fractional exponent. Here is a table of some common exponent rules with examples:
| Rule | Example |
[tex]| x^1 = x | 6^1 = 6 |[/tex]
[tex]| x^0 = 1 | 7^0 = 1 |[/tex]
[tex]| x^-1 = 1/x | 4^-1 = 1/4 |[/tex]
[tex]| x^m * x^n = x^(m+n) | 2^3 * 2^4 = 2^(3+4) = 2^7 |[/tex]
[tex]| x^m / x^n = x^(m-n) | 2^5 / 2^3 = 2^(5-3) = 2^2 |[/tex]
[tex]| (x^m)^n = x^(mn) | (2^3)^2 = 2^(3*2) = 2^6 |[/tex]
[tex]| (xy)^n = x^n * y^n | (3*4)^2 = 3^2 * 4^2 |[/tex]
[tex]| (x/y)^n = x^n / y^n | (4/2)^3 = 4^3 / 2^3 |[/tex]
[tex]| x^(m/n) = n-th root of x^m | 2^(6/3) = cube root of 2^6 |[/tex]
We can use these rules to simplify expressions with exponents or to perform calculations with them.
Therefore, by exponentiation answer will be given.

A school sells pizza slices at the concession stand during each sporting event. The school sells a mean of
200 slices per event with a standard deviation of 25 slices.
The school spends $160 of fixed costs to buy the pizza before the event and earns a revenue of $2 per
slice. They calculate their profit per event according to this formula:
profit
(total revenue) – (total costs]
What will be the mean and standard deviation of the distribution of profit per event?
Answer:
μ = $240
σ = $50
Step-by-step explanation:
Profit is revenue minus cost:
P = R – C
The revenue is $2 times the number of slices sold, and the cost is $160.
P = 2x – 160
The average profit is:
μ = 2(200) – 160
μ = 240
The standard deviation is:
σ = 2(25)
σ = 50

How many triangles can be constructed with side lengths of 6.4 cm, 8.3 cm, and 14.6 cm? 0 1 more than one
Answer:
Only one triangle is possible.
Step-by-step explanation:
Triangle inequality says that if sum of any two sides of the traingle is greater than the third side, then the triangle is possible.
Here,
,
Therefore, a triangle is possible with the given measurements,
Let us assume there is another triangle with same measurement with same measurements 7 cm, 6 cm, and 9 cm.,
By SSS congruency criteria both the triangles will be congruent.
Thus, all triangles with same measurement will be congruent to each other.
Hence, only one triangle is possible.
