a triangle has sides with lengths of 5x, 15 and 17. the perimeter of the triangle is 45 meters. what is the value of x?
The value of 'x' will be;
⇒ x = 13/5
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
A triangle has sides with lengths of 5x, 15 and 17.
And, The perimeter of the triangle is 45 meters.
Now,
Since, the perimeter of the triangle is 45 meters.
Hence, We can formulate;
⇒ 5x + 15 + 17 = 45
Solve for x as;
⇒ 5x + 32 = 45
⇒ 5x = 45 - 32
⇒ 5x = 13
⇒ x = 13/5
Thus, The value of 'x' will be;
⇒ x = 13/5

If f(x) = 3x2 – 2 and g(x) = 2x + 4, find (f – g)(x).
A. 3x2 – 2x – 6
B. 2x – 3x2 – 2
C. 3x2 – 2x + 2
D. x2 + 2
The correct answer is:A. 3x^2 −2x−6
To find (f−g)(x), you subtract g(x) from f(x).
So,(f−g)(x)=f(x)−g(x)
Given that
f(x)=3x^2 −2 and g(x)=2x+4, let's substitute these into the expression:
(f−g)(x)=(3x^2 −2)−(2x+4)
Now, distribute the negative sign:
(f−g)(x)=3x^2 −2−2x−4
Combine like terms:
(f−g)(x)=3x^2 −2x−6
So, the correct answer is:A. 3x^2 −2x−6

which of the following is a solution to 4cos^2x-1=0?
60°
150°
210°
330°
Answer:
Option A- 60°
Step-by-step explanation:
Given : Function - [tex]4cos^2x-1=0[/tex]
To solve the function
Step 1 - Write the function
[tex]4cos^2x-1=0[/tex]
Step 2- Add 1 both side
[tex]4cos^2x=1[/tex]
Step 3- Divide 4 both side
[tex]cos^2x=\frac{1}{4}[/tex]
Step 4 - Taking root both side
[tex]cosx=\sqrt{\frac{1}{4}}[/tex]
Step 5 - solve
[tex]cosx=\pm{\frac{1}{2}}[/tex]
Either [tex]cosx={\frac{1}{2}}[/tex] or [tex]cosx=-{\frac{1}{2}}[/tex]
When [tex]cosx={\frac{1}{2}}[/tex]
[tex]\rightarrow cosx={cos\frac{\pi}{3}}[/tex]
[tex]\rightarrow x={\frac{\pi}{3}} or 60^{\circ}[/tex]
or when [tex]cosx=-{\frac{1}{2}}[/tex]
[tex]\rightarrow cosx={cos(\pi-\frac{\pi}{3})}[/tex]
[tex]\rightarrow x={\frac{2\pi}{3}} or 120^{\circ}[/tex]
Therefore, Option A is correct solution of function is at 60°.
The solution of the given trigonometric ratio for the expression 4cos²x - 1 = 0 is equal to 60°
To find the solutions to the equation 4cos²x - 1 = 0, we first need to isolate the cosine term and then solve for x.
Let's go through the steps,
Add 1 to both sides of the equation:
4cos²x = 1
Divide both sides by 4:
cos²x = 1/4
Take the square root of both sides:
cosx = ±√(1/4)
Now, we have two cases to consider: positive and negative square roots.
Case 1,
cosx = √(1/4)
The cosine of an angle can never be negative when expressed in degrees, so we ignore the negative square root.
cosx = √(1/4) = 1/2
To find the angles for which the cosine is 1/2, we look at the unit circle or use a calculator to find the inverse cosine (arccos) values:
x = arccos(1/2)
The principal angle that satisfies this is x = 60°.
Case 2,
cosx = -√(1/4)
Again, we ignore the negative square root as the cosine is not negative in degrees.
Therefore, the only solution to the equation is:
x = 60°
Therefore, among the given options, the solution to 4cos²x - 1 = 0 is 60°.

max donated 16 collars to the dog shelter . Mia donated some leashes. hiw many items does Mia need to donate that would require you to regroup to find the total number of items donated?
Answer:
4.
Step-by-step explanation:
To find the total, we would be adding together Max's donated items and Mia's donated items.
"Regrouping" is just another way of stating that we have to carry in the addition.
If we add 16+1, there is no carrying or regrouping.
If we add 16+2, there is no carrying or regrouping.
If we add 16+3, there is no carrying or regrouping.
If we add 16+4, we must carry (regroup). This is because 6+4 = 10, so we carry 1 to the tens place. This is the first time we would regroup this number.
To regroup is another term used for "carry" in arithmetic operations
The least number of items Mia would add, that would require regroup is 4
From the question, we have:
[tex]Max= 16[/tex]
When 1, 2 or 3 are added to 16, there is no "carry" operation.
Because, they are all straight addition operations
[tex]16 + 1 = 17[/tex]
[tex]16 + 2= 18[/tex]
[tex]16 + 3 = 19[/tex]
However, when 4 is added to 16, there is a need to regroup.
The addition is illustrated as follows:
[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\&&\end{array}\right][/tex]
Add 6 and 4;
The result is 10.
So, we write down 0, and "carry" 1
[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\&0&\end{array}\right][/tex]
Next, add 1 (the one beside 6) to the 1 we carried in the previous addition
The result is 2
[tex]\left[\begin{array}{ccc}1&6\\ +&4&\\2&0&\end{array}\right][/tex]
The process of "carrying" is what is referred to as regroup
So, the least number of items Mia would add, that would require regroup is 4

in January 2011 the rate of VAT increased from 17.5% to 20%
work out the difference in price of a car worth £15000 +VAT due to increase in VAT
The difference in price of a car is £375 it is due to the rate of VAT increase from 17.5% to 20% and this can be evaluated by the help of unitary method.
Given :
Rate of VAT increased from 17.5% to 20%.
Total price of a car = £15000 + VAT.
In this problem unitary method can be used to determine the difference in price of a car which is due to the increased rate of VAT.
The price of VAT when its' rate is 17.5% can be:
[tex]= \dfrac{15000}{100} \times 17.5[/tex]
= £ 2625
Therefore, the total price of car when VAT is 17.5% is £17625.
The price of VAT when its' rate is 20% can be:
[tex]= \dfrac{15000}{100} \times 20[/tex]
= £ 3000
Therefore, the total price of car when VAT is 20% is £18000.
So, the difference in price of car = 18000 - 17625 = £375.

Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $ 2 0 0 $200dollar sign, 200 a month and an additional $ 1 2 $12dollar sign, 12 for each album that he sells. Last month he earned a total of $ 6 4 4 $644dollar sign, 644. Write an equation to determine the number of albums ( a ) (a)left parenthesis, a, right parenthesis Floyd sold last month. Find the number of albums Floyd sold last month.
To find the number of albums Floyd sold last month, we calculate it using the linear equation $644 = $200 + ($12 \u00d7 a), where $644 is the total earnings, $200 is the base rate, and $12 is the amount earned per album. Floyd sold 37 albums last month.
Explanation:To determine the number of albums Floyd sold last month, we can set up a linear equation based on the information provided. Floyd is paid a base rate of $200 per month, and he earns an additional $12 for every album sold. The total amount Floyd earned last month was $644.
Let's let a represent the number of albums sold. The equation that represents the total earnings for the month would be:
Total Earnings = Base Rate + (Number of Albums Sold × Price per Album)
Based on what has been given, we can express this as:
$644 = $200 + ($12 × a)
To find the number of albums sold, we subtract the base rate from the total earnings, then divide by the additional amount earned per album:
$644 - $200 = $12 × a
$444 = $12 × a
a = $444 / $12
a = 37
So, Floyd sold 37 albums last month.

suppose that Y and Z are points on the number line if YZ=11 and Y lies on -9 where would Z be located
Final answer:
Point Z is located at 2 on the number line, found by adding the distance YZ=11 to the location of Y at -9.
Explanation:
If Y and Z are points on the number line, YZ=11, and Y lies on -9, to find where Z would be located, you simply add the distance between Y and Z to the point Y. Since the distance YZ=11, and Y is at -9 on the number line, you add 11 to -9 to find Z.
Therefore, the location of point Z will be:
-9 + 11 = 2
So, point Z is located at 2 on the number line.
