A triangle has side lengths of (7n-2p)(7n−2p) centimeters, (2n+4q)(2n+4q) centimeters, and (q-5p)(q−5p) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answers
Answer:
(7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p) OR
53n² +29p² +17q² -14np +8nq -10pq
Step-by-step explanation:
The perimeter is found by adding all the side lengths.
P = (7n-2p)(7n−2p) + (2n+4q)(2n+4q) + (q-5p)(q−5p)
We know that (a+b)(a+b) = (a+b)², and (a-b)(a-b) = (a-b)²
P = (7n-2p)² + (2n+4q)² + (q-5p)²
We know that (a+b)² = a²+b²+2ab, and (a-b)² = a²+b²-2ab
P = 49n² + 4p² - 14np +4n² +16q² + 8nq +q²+25p² -10pq
Combine like terms
P = 53n² +29p² +17q² -14np +8nq -10pqWhat is -2/3 - (-1/2)
Answers
Answer: -1/6
Step-by-step explanation: Start by changing the minus a negative
to plus a positive, so we have -2/3 + 1/2.
Since our denominators of 3 and 2 have no factors in common,
our least common denominator is 3 · 2 or 6.
In order to get a denominator of 6 in each fraction,
we multiply top and bottom of the first fraction by 2
and top and bottom of the second fraction by 3.
That gives us -4/6 + 3/6 which simplifies to -1/6.

Answer:
857.4 ohms
Step-by-step explanation:
The new frequency is 50.2/61.4 times the old frequency. Since the reactance varies inversely with frequency, the new reactance will be 61.4/50.2 times the old reactance:
reactance at lower frequency = (701 ohms)×61.4/50.2 ≈ 857.4 ohms

Write a relationship for a function whose g(x) values are 2 more than five times the principal square root of x.
Answers
Lets do
2 more than five times the square root of x[tex]\\ \sf\longmapsto g(x)=5\sqrt{x}+2[/tex]
Lets take an example
[tex]\\ \sf\longmapsto g(4)=5\sqrt{4}+2[/tex]
[tex]\\ \sf\longmapsto 5(2)+2[/tex]
[tex]\\ \sf\longmapsto 10+2[/tex]
[tex]\\ \sf\longmapsto 12[/tex]
“5 times” means “multiply by 5”.
The principal square root just means the regular square root.
Putting that together, you have
g(x) = 5 * sqrt(x) + 2
You have a lead ball with a mass of 360 g. The density of lead is 15 g/cm3. What is the volume of the ball?
Answers
Recall that density = mass / volume.
Let's plug our known values into the equation.
15 g/cm^3 = 360g / volume
First, let's multiply both sides by volume
Volume * 15 g/cm^3 = 360g
Divide both sides by 15 g/cm^3
Volume = 24 cm^3
Density is defined as the mass per unit of volume. The volume of the ball is 24 cm³.
What is density?Density is defined as the mass per unit of volume. It is given by the formula,
Density = Mass / Volume
Given that You have a lead ball with a mass of 360 g. The density of lead is 15 g/cm³.
Now, since density is the ratio of mass and volume. Therefore, we can write the volume of the ball as,
Density = Mass / Volume
Volume = Mass / Density
Volume of the ball = 360g / 15g/cm³
= 24 cm³
Hence, the volume of the ball is 24 cm³.

Limits of a Function
If [tex]\displaystyle \lim_{x \to 1} \frac{f(x)-8}{x-1} = 10,[/tex] find [tex]\lim_{x \to 1} f(x).[/tex]
Answers
We are given the equation:
[tex]\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10[/tex]
which can be rewritten as:
[tex]\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10[/tex]
[tex]\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1][/tex]
[tex]\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10][/tex]
which means that..
[tex]f(x) - 8 = 10x - 10[/tex]
[tex]f(x) = 10x - 10 + 8[/tex]
[tex]f(x) = 10x - 2[/tex]
Finding the limit:
[tex]\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)[/tex]
[tex]\lim_{x \to 1} f(x) = 10(1) - 2[/tex]
[tex]\lim_{x \to 1} f(x) = 8[/tex]
Answer:
8.
Step-by-step explanation:
lim x --> 1 of 10x - 10 / (x - 1)
= lim x -->1 of 10/1 ( Because when x = 1 the function = 0/0 so we can apply
L'hopitals rule which states that that if f(x)/ g(x) = 0/0 when x = limit value, then the limit is = f'(x) / g'(x))
So f(x) - 8 = 10x - 10
f(x) = 10x - 10 + 8
f(x) = 10x - 2
- and the limit as x ---> 1 of this is
10(1) - 2
= 8.

What is Unitary method?"It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary MethodFirst, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
Total money = $225.00
Cost of one ball =$55
So, remaining money after buying the ball
=225- 55
= $170
Now,
game of bowling costs $3.50,
So, number of bowling can be played is
=170/3.5
=48.75
= 48 bowling
