as part of a science experiment, Carson designs and creates a cushioned egg carrier. he puts an egg inside it and then drops it from a window to see whether his design can safely cushion the egg and keep it from breaking. the egg's height in feet x seconds after being dropped is given by 27 - 16x^2. after how many seconds will the egg hit the ground?
Answer: To find out how many seconds it will take for the egg to hit the ground, we need to find the value of x when the height of the egg is 0 feet. We can do this by setting the height of the egg equal to 0 in the equation 27 - 16x^2 and solving for x.
The equation for the height of the egg in feet x seconds after being dropped is given as:
27 - 16x^2 = 0
Subtracting 27 from both sides of the equation gives us:
-16x^2 = -27
Dividing both sides of the equation by -16 gives us:
x^2 = 27/16
Taking the square root of both sides of the equation gives us:
x = sqrt(27/16)
Plugging this value into the equation for the height of the egg gives us:
27 - 16(sqrt(27/16))^2 = 0
Simplifying this equation gives us:
27 - 16(27/16) = 0
Which simplifies to:
27 - 27 = 0
This equation is true, so the value of x that we found is a solution to the equation. This means that the egg will hit the ground after sqrt(27/16) seconds.

4. A function h(x) has an average rate of change equal to 7 on the interval 5 ≤ x≤ 9. If h(5)=12, then which of the following must be the value of h(9) ?
3) The rate of change on the interval [1, 7] is -1, so the correct option is A.
4) By using the rate of change formula, we will see that h(9) = 40
How to find the average rate of change?We know that for a function f(x), the average rate of change on the interval [a, b] is:
r = ( f(b) - f(a))/(b - a)
Here the interval is [1, 7]
Using the graph we can see that:
f(1)= 6
f(7) = 0
Then the average rate of change is:
r = ( f(7) - f(1))/(7 - 1)
r = (0 - 6)/6 = -1
The correct option is A.
4) Which will be value of h(9)?
We know that the average rate of change of h(x) is 7 on the interval [5, 9]
Then we can write:
7 = ( h(9) - h(5))/(9 - 5)
We know that h(15) = 12, then we have the equation:
7 = (h(9) - 12)/4
Now we can solve that for h(9), we will get:
7 = (h(9) - 12)/4
7*4 = h(9) - 12
28 = h(9) - 12
28 + 12 = h(9)
40 = h(9)

Answer: No, 2/4 is not greater than 2/3
Step-by-step explanation: To find an easy way to calculate their values we have 2 options. So, the 1st option is to turn them into a decimal. I already calculated their values which are:
2/4 = 0.5
2/3 = 0.667
Then, we compare the two decimal numbers to get the answer.
0.5 is not greater than 0.667.
The 2nd way is to find a common denominator, which would look like this:
2/4 = 6/12
2/3 = 8/12
8/12 is greater than 6/12, so that also proves that 2/4 is not greater than 2/3.

The pressure of 28 inches of mercury occurs about 6 miles from the eye of the hurricane. We get this from the given algebraic expression.
What is an expression?An expression is formed by variables, constants, and algebraic operations. Since the operation among them is an algebraic or arithmetic operation, it is said to be an algebraic expression.
Calculation:It is given that the algebraic expression that relates the barometric pressure and the eye of the hurricane as
f(x) = 0.48 ln(x+2) + 27
Here x is the distance in miles from the eye of the hurricane.
f(x) is the pressure of the mercury in a barometer in inches
So, the required distance from the eye of the hurricane when the pressure of 28 inches of mercury in the meter is
(Here f(x) = 28)
f(x) = 0.48 ln(x+2) + 27
⇒ 28 = 0.48 ln(x+2) + 27
⇒ 0.48 ln(x+2) = 28 - 27
⇒ ln (x+2) = 1/0.48
⇒ ln(x+2) = 2.0833
Applying exponential base "e" on both sides, we get
(x+2) = [tex]e^{2.0833}[/tex]
⇒ x + 2 = 8.0309
⇒ x = 8.0309 - 2 = 6.0309
When the result is rounded to the nearest whole number, we get x = 6 miles.
Thus, for the pressure of 28 inches of mercury, the eye of the hurricane is 6 miles far from the barometer.

It takes 11.55 years for money to double if invested at 6% compound interest.
What is compound interest?
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.Calculating the answer exactly: P⁰°⁰⁶ⁿ=A .
We don’t know the initial value of the principal but we do know that the accumulated value is double (twice) the principal.
P⁰°⁰⁶ⁿ = 2P
We divide both sides by P
e⁰°⁰⁶ⁿ = 2
Using natural logarithm:

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, y=x²-10x+30 -------(I) and y=4x-3 -------(II)
Substitute equation (II) in the equation (I), we get
4x-3=x²-10x+30
⇒ x²-10x+30-4x+3=0
⇒ x²-14x+33=0
⇒ x²-11x-3x+33=0
⇒ x(x-11)-3(x-11)=0
⇒ (x-11)(x-3)=0
⇒ x=11 and x=3
So, y=4(11)-3=41 and y=4(3)-3=9
Therefore, the solutions to the quadratic linear system equations are (11, 41) and (3, 9).

(a) 794g of the initial sample will be left in the sample after 25 years. (b) Time taken to decay to half of its original amount is 3.39 years.
Isotopes(200g) are atoms that have the same number of protons in their nucleus, but a different number of neutrons. This means that they have the same atomic number, but a different atomic mass. Because of this, isotopes have different physical and chemical properties. Isotopes can be stable, meaning that they do not undergo radioactive decay, or they can be unstable, meaning that they will undergo radioactive decay over time.
(a) Substituting 25 for t in the expression, we get:
[tex]A(25) = 200e^{0.0541 \times 25}[/tex]
[tex]= 200e^{1.3525}[/tex]
Thus, after 25 years, there will be
[tex]200e^{1.3525} = 2003.97[/tex]
794 g of the initial sample left in the sample.
(b) We want to find t such that
[tex]A(t) = 200e^{0.0541}[/tex]
= 100.
Solving for t, we get:
[tex]= 200e^{0.0541} \times t=100[/tex]
Dividing both sides by 200 and applying the natural logarithm to both sides, we get:
0.0541 × t = ln(0.5)
Therefore,
[tex]t = \frac{ln(0.5)}{0.0541}[/tex]
= 3.39 years.

What is the remainder when 2^70 + 3^70 is divided by 13?
Answer: hope it helps
Step-by-step explanation:
2^6=64≡ -1 ( mod 13)
So 2^70=16*(2^6)^11=16*(-)^11(mod 13)
2^70 ≡-16 ( mod 13)
2^70 ≡10 ( mod 13)
Now 3^3=27≡1 ( mod 13)
So 3^70= 3*(3^3)^23≡ 3*(1)^23 ( mod 13)
≡ 3 ( mod 13)
Thus 2^70+3^70 ≡ 10+3 (mod 13)
≡ 0 ( mod 13)
