Answer:
Option C.
Step-by-step explanation:
If we have two functions:
f(x) and g(x)
the product is given by:
(f*g)(x) = f(x)*g(x)
So, if here we have
f(x) = √(3*x)
g(x) = √(48*x)
And remembering that the square root is distributive, so:
√a*√b = √(a*b)
We can write:
(f*g)(x) = f(x)*g(x) = √(3*x)*√(48*x) = √(3*x*48*x)
= √(3*48*x*x) = √(144*x^2) = √(144)*√(x^2)
And here we can use that:
12*12 = 144, then √144 = 12
and
x*x = x^2, then √x^2 = x
So:
√(144)*√(x^2) = 12*x
Then the correct option is C.
In order to determine if there is a significant difference between campuses and pass rate, the chi-square test for association and independence should be performed. What is the expected frequency of West Campus and failed
Answer:
57.5
Step-by-step explanation:
The expected frequency of West Campus and Failed :
Let :
Failed = F
East Campus = C
West Campus = W
Passed = P
Frequency of FnW :
[(FnE) + (FnW) * (PnW) + (FnW)] / total samples
[(52 + 63) * (63 + 37)] / 200
[(115 * 100)] / 200
11500 / 200

Compare the temperature change for the two masses of cold water (50 grams and 100 grams) when the same amount of hot water was added. What do you discover?
Answer:
Step-by-step explanation:
All other things being equal (and there are a lot of other things) the 50 gram mass will show a larger temperature
increase than the 100 gram mass.
Why?
The formula is the same from both masses of water (50 grams and 100 grams)
The amount of heat added is the same. (Instead of using hot water, we'll a hot plate on a very low temperature but above what they are now.).
We'll leave it on until we see a rise in temperature delta(t1) = 10 degrees
mc delta(t) = m1 * c * delta(t1)
m = 100
m1 = 50 grams.
c is going to be divided out
we'll solve for the ratio of delta(t) / delta(t1)
100 * delta(t) = 50 (delta(t1)
100 * delta(t) = 50*10
delta(t) = 50*10/100
delta(t) = 5 degrees.
Though this may look rather convoluted, the result is telling us is that delta(t1) for the 50 gram mass is twice as big as as for the 100 gram mass.
The 100 gram mass only rises 5 degrees.
The 50 gram mass rises 10 degrees.
Answer:
50 gram mass will show a larger temperature
increase than the 100 gram mass.
Step-by-step explanation:
50 gms water at 20 ⁰ C and 50 gms of water at 40⁰ C are mixed. Since the masses of the liquid at different temperatures are same, the answer is very easy and simple : average of 20⁰C and 40⁰C. that is: 30⁰C.

The answer for this question is 64 square centimeters
Step-by-step explanation:
To find the area of square , the formula is :

A tub contain 10 litre 600 millitres of water, if 9 litre 400 millitres of water is further added to its, what will be total water in the tub?
Answer:
If 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
Step-by-step explanation:
Given that a tub contains 10 liters 600 millitres of water, to determine, if 9 liters 400 millitres of water is further added to this, what will be total water in the tub, the following calculation must be performed:
1 liter = 1000 milliliters
0.6 liters = 600 milliliters
10.6 + 9.4 = X
20 = X
Therefore, if 9 liters 400 millitres of water is further added, there will be 20 liters of water in the tub.
Compound interest
Plz help!!!
Answer:
a) [tex]A(t) = 17500(1.0053)^{12t}[/tex]
b) The balance after 8 years will be of $29,069.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
a)
Loan of $17,500 means that [tex]P = 17500[/tex]
6.4% interest rate means that [tex]r = 0.064[/tex]
Compounded monthly means that [tex]n = 12[/tex]. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(t) = 17500(1 + \frac{0.064}{12})^{12t}[/tex]
[tex]A(t) = 17500(1.0053)^{12t}[/tex]
b)
This is A(8). Then
[tex]A(8) = 17500(1.0053)^{12*8} = 29069[/tex]
The balance after 8 years will be of $29,069.

Describe the transformation of f(x) to g(x).
g(x)
O A. f(x) is shifted down 2 units to g(x).
O B. f(x) is shifted up 2 units to g(x).
O c. f(x) is shifted up 5 units to g(x).
OD. (x) is shifted down units to g(x)
The transformation of f(x) to g(x) is f(x) is shifted down 2 units to g(x).
The correct option is (A)
What if transformation of a function?
Transformations of functions mean transforming the function from one form to another. Transformation of functions is a unique way of changing the formula of a function minimally and playing around with the graph.
The given function f(x)= sin x
In the graph there is vertical shift from f(x) to g(x)
We know, the vertical shift depends on the value of k
When k>0, the vertical shift is described as
g(x)=f(x)+k- The graph is shifted up k units.g(x)=f(x)−k - The graph is shifted down k units.If we closely look at the graph the vertical distance in negative y-axis,
the distance between line f(x) and g(x) is from 0 to -2.
So, there is shifting of -2 units means there is downward shifting.
i.e., k=2
Hence, f(x) is shifted down 2 units to g(x).

Which expression represents the length of the hypotenuse, c, of the triangle below?
Pleaseeeeee I neeed helpppp
Answer:
C) [tex]c=\sqrt{a^{2} +b^{2} }[/tex]
Step-by-step explanation:
The Pythagorean Theorem states that for a right triangle, the relationship between its three sides is [tex]a^{2} +b^{2} =c^{2}[/tex] where [tex]a[/tex] and [tex]b[/tex] are side lengths and [tex]c[/tex] is the length of the hypotenuse. This means that the length of the hypotenuse is [tex]c=\sqrt{a^{2} +b^{2} }[/tex] by taking the square root of both sides to solve for [tex]c[/tex], making option C correct.

Step-by-step explanation:
Given
The attached triangle

Find BD and BC
Solving BD
Considering angle at D, we have:
[tex]\cos(D) = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos(60) = \frac{BD}{8}[/tex]
Solve for BD
[tex]BD = 8 * \cos(60)[/tex]
[tex]\cos(60) = 0.5[/tex] So:
[tex]BD = 8 * 0.5[/tex]
[tex]BD = 4[/tex]
To solve for BC, we make use of Pythagoras theorem
[tex]CD^2 = BC^2 + BD^2[/tex]
This gives
[tex]8^2 = BC^2 + 4^2[/tex]
[tex]64 = BC^2 + 16[/tex]
Collect like terms
[tex]BC^2 =64-16[/tex]
[tex]BC^2 =48[/tex]
Take square roots
[tex]BC =\sqrt{48[/tex]
Expand
[tex]BC =\sqrt{16*3[/tex]
Split

Pizza Uno offers 2/3 of a small pizza for $3.50. Pizza Duo offers % of a small pizza for $4.20. How much does each charge for a whole small pizza?
Show your work and remember to answer the question.
PLSS ANSWER!!!! ILL GIVE BRAINLIEST!
Answers:
Pizza Uno = $5.25Pizza Duo = $5.60Those are the costs for a whole small pizza.
==========================================================
Explanation:
Let
x = cost of whole small pizza from Pizza Unoy = cost of whole small pizza from Pizza Duox and y are some dollar amount, so they cannot be negative numbers. It also doesn't make sense to have them be 0 either. So we'll make them positive.
2/3 of x is equal to 3.50 as the first sentence mentions. This forms the equation (2/3)*x = 3.50
Multiply both sides by the reciprocal of 2/3 to isolate x
(2/3)*x = 3.50
(3/2)*(2/3)*x = (3/2)*3.50
x = 5.25
Pizza Uno charges $5.25 for a whole small pizza.
----------------------------
Pizza Duo charges $4.20 for 3/4 of a small pizza, meaning the equation we need to solve is
(3/4)y = 4.20
We'll use the same idea as the last equation to get...
(3/4)y = 4.20
(4/3)*(3/4)y = (4/3)*4.20
y = 5.60
Pizza Duo charges $5.60 for a whole small pizza.
Pizza Uno is the better deal (assuming both pizzas taste the same or you don't have a preference for either). You would save $5.60 - $5.25 = $0.35 = 35 cents.
