Since the function and choices are already given, the simplest method would be to try out the given values of x and see if the value of y obtained and given int he choices would coincide. Using this trial and error method, it has been shown that the correct answer among the choices is choice C, with the solution shown below:
y = -0.296x^2 + 2.7x
Using (4.6, 6.2):
y = -0.296(4.6)^2 + 2.7(4.6)
y = 6.2
The answer is 2/3. Since you need our denominator to be 3 just find a number that divides 12 three times. Since 12/4 is 3 you have your denominator and because you used 4 on the denominator you must do it on the numerator so 8/4 is 2.
I hope I helped!
<u>What we'll do:</u>
A method to find whether an object will float or sink in a liquid is to find it's specific gravity with respect to the liquid, The Specific Gravity tells us the percentage of object's mass which will be submerged in water
<u>Finding the Specific Gravity:</u>
<u>Density of Box:</u>
Density = Mass / Volume
Density = 80 grams / 78 cm³
Density = 1.02 grams/cm³
<u>Specific Gravity of Box with respect to water:</u>
Specific Gravity = Density of Box / Density of Water
we know that density of water is 1 gm/cm³, plugging the values
Specific Gravity = 1.02 / 1
Specific Gravity = 1.02
Hence, 102% of the object will be under water
Q. but I've only heard about 100% of something, how can something be more than 100%?
A. The answer is that the extra 2% over the 100% is providing to the object being even deeper underwater
The value of p(1) is 2
<h3>What is the value of p(1)?</h3>
The function definition is given as:
P(x) = -3(x - 2)^2 + 5
The expression P(1) means that x =1
So, we have:
P(1) = -3(1 - 2)^2 + 5
Evaluate the difference
P(1) = -3(-1)^2 + 5
Evaluate the square
P(1) = -3 * 1 + 5
This gives
P(1) = 2
Hence, the value of p(1) is 2
