Answer:
5 - x
Step-by-step explanation:
Given:
\(f(x)=25-x^2\)
\(g(x)=x+5\)
\(\begin{aligned}\left(\dfrac{f}{g}\right)(x) & = \dfrac{f(x)}{g(x)}\\\\ & = \dfrac{25-x^2}{x+5}\\\\& = \dfrac{(5-x)(5+x)}{(x+5)}\\\\& = \dfrac{(5-x)(x+5)}{(x+5)}\\\\& = 5-x\end{aligned}\)
Answer:
\(\sf \left(\dfrac{f}{g}\right)(x)=5-x\)
Step-by-step explanation:
Given functions:
f(x) = 25 - x²
g(x) = x + 5
Difference of Perfect Squares rule: a² - b² = (a + b)×(a - b)
1. Rewrite function f(x) using the rule:
5 × 5 = 25 ⇒ 5²
x × x = x²
f(x) = 5² - x² ⇒ f(x) = (5 + x)×(5 - x)
2. Divide and simplify:
\(\sf\left(\dfrac{f}{g}\right)(x) =\dfrac{f(x)}{g(x)}\\\\\left(\dfrac{f}{g}\right)(x)=\dfrac{(5 + x)(5 - x)}{x+5}\\\\\left(\dfrac{f}{g}\right)(x)=5-x\)
Compare the quadratic function f(x) = 2(x - 2)? + 8 with the following graph of g(x)
The statement that is completely correct is option The minimum value of f(x) is greater than the maximum value of g(x).
What is the quadratic function?From the question given, the quadratic function is f(x) = 2(x - 2)² + 8
Note therefore that:
When X=2f(x) minimum = 8.Based on the graph given (see image attached) we are able to see the vertex of g(x) is (2, 3), the maximum of g(x) is said to be 3.
So one can say that the {8 > 3} hence the minimum value of f(x) is greater than the maximum value of g(x).

=============================================
Explanation:
Let point N be at the intersection of the horizontal line and segment JM.
We can prove the right triangles JNK and MNK are congruent using the hypotenuse leg (HL) rule. This in turn means JN = NM through the use of CPCTC.
In other words, JN = NM because the horizontal line is the perpendicular bisector of JM.
So,
JM = JN + NM
JM = NM + NM
JM = 2*NM
JM = 2*7.1
JM = 14.2
Answer:
JM = 14.2
Step-by-step explanation:
Given JK = MK then Δ JKM is isosceles.
The line through K is a perpendicular bisector of JM , so
JM = 2 × 7.1 = 14.2

Option A,B,C,D : Elias might have gotten the answer by calculating the percentage discounts of each item and comparing them to see which ones are the same.
To find which items have the same percent discount, we need to calculate the percent discount for each item.
For the sweater, the percent discount is (20/50) x 100% = 40%.
For the shorts, the percent discount is (12/30) x 100% = 40%.
For the shirt, the percent discount is (14/35) x 100% = 40%.
For the jeans, the percent discount is (24/60) x 100% = 40%.
Therefore, all items have the same percent discount of 40%, and option C (jeans and shirt only) is incorrect. The correct answer is A, sweater and shorts only, B, sweater, shorts, and shirt only, and D, sweater, shorts, and jeans only, have the same percent discount. Elias may have chosen C because he overlooked that the percent discount is the same for all items.

You consistently deposit $250. 00 into a savings account on the 15th of each month, and the amount earns a 2. 5 APR How much is the balance of your savings account at the end of the 3rd full month?
The balance of your savings account at the end of the 3rd full month is $754.69.
To calculate the balance of your savings account at the end of the 3rd full month, we need to first calculate the total amount deposited over those three months:
Total deposited = $250 x 3 = $750
Next, we need to calculate the interest earned on that deposit. We can use the formula:
Interest = Principal x Rate x Time
where:
Principal is the initial amount deposited
Rate is the annual percentage rate (APR)
Time is the time period for which interest is being calculated
In this case, the principal is $750, the APR is 2.5%, and the time period is 3/12 (or 0.25) years, since we are calculating interest for 3 months out of a 12-month year.
Plugging in the values, we get:
Interest = $750 x 0.025 x 0.25 = $4.69
Therefore, the interest earned over the 3 months is $4.69.
The balance of your savings account at the end of the 3rd full month will be the total amount deposited plus the interest earned:
Balance = Total deposited + Interest earned
Balance = $750 + $4.69
Balance = $754.69
Therefore, the balance of your savings account at the end of the 3rd full month is $754.69.

A carpenter has a bundle of wood boards that are all 5 * root(4, 10) feet long. He was told by the contractor to cut 2 * root(4, 10) off the end of each board in the bundle. What is the length of each of the boards after removing the root(4, 10) sections of wood ?
Answer:
The length of each board will be 3 * root(4, 10) feet
Step-by-step explanation:
The parameters given are;
The length, L₁, of each board in the bundle = 5 * root(4, 10) feet
The length, Lₓ, to be cut off from each board in the bundle = 2 * root(4, 10) feet
Therefore, the length, L₂, of each of the boards after removing the 2 * root(4, 10) sections of the wood would be given as follows;
L₂ = 5 * root(4, 10) feet - 2 * root(4, 10) feet = 3 * root(4, 10) feet

Find the volume of radius 7 cm in diameter of 12 cm in 3.14
The volume of a sphere with a radius of 7 cm (or diameter of 12 cm) is 904.32 cubic centimeters.
To find the volume of a sphere with a radius of 7 cm, we can use the formula:
V = (4/3) * π * r^3
where V represents the volume and r represents the radius. However, you mentioned that the diameter of the sphere is 12 cm, so we need to adjust the radius accordingly.
The diameter of a sphere is twice the radius, so the radius of this sphere is 12 cm / 2 = 6 cm. Now we can calculate the volume using the formula:
V = (4/3) * π * (6 cm)^3
V = (4/3) * 3.14 * (6 cm)^3
V = (4/3) * 3.14 * 216 cm^3
V = 904.32 cm^3

Which statement about this figure is true ?
a. it has reflection al symmetry with one line of symmetry
b. it has no rotational symmetry
c. it has no rotational symmetry with an angle of rotation of 90 degrees
d. it has no reflectional symmetry
The statement that is true about the given figure, a limaçon, is c. It has no rotational symmetry, with an angle of rotation of 90 degrees.
Let's examine each option and explain why they are true or false:
a. It has reflectional symmetry with one line of symmetry: This option is false. To have reflectional symmetry with one line of symmetry, the figure must be identical on both sides when divided by a line. The given figure, a limaçon, does not exhibit this property.
b. It has no rotational symmetry: This option is true. Rotational symmetry means that the figure remains unchanged after rotation by certain angles. The limaçon does not have any rotational symmetry because it does not appear the same after any rotation.
c. It has no rotational symmetry, with an angle of rotation of 90 degrees: This option is true. A figure with rotational symmetry of 90 degrees would appear the same after a 90-degree rotation. However, the limacon does not exhibit this property.
d. It has no reflectional symmetry: This option is true. Reflectional symmetry requires the figure to have a line of symmetry dividing it into two identical halves. The limaçon does not possess such a line of symmetry.
Based on the explanations above, the correct statement is that the limaçon has no rotational symmetry with an angle of rotation of 90 degrees (option c).

An element with a mass of 400 grams decays by 29.8% per minute. To the nearest
minute, how long will it be until there are 2 grams of the element remaining?
The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.
We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.
M = m(1 - r)^t
2 = 400(1 - 0.298)^t
0.005 = (0.702)^t
log(0.005) = t*log(0.702)
t = log(0.005)/log(0.702)
t = 14.97

Two cars leave the park at the same time opposite directions one goes 3 times faster after 6 hours they travel 140miles how fast did theyg go
Answer:
Their speeds are;
5.83 mph and 17.49 mph
Step-by-step explanation:
We are told that they leave the park the same time.
Let the speed one car traveled be v
Since the other car is 3 times faster, then it means that, it's speed is 3v.
Now, after 6 hours they travel 140 miles.
We know that;
Speed = distance/time.
Thus;
(v + 3v) = 140/6
4v = 140/6
v = 140/24
v = 5.83 mph
Thus, second car's speed = 3v = 3 × 5.83 = 17.49 mph
Given the linear equation r=-2. 5 t and t can only be a negative number, what quadrant will the r coordinate be located?.
The coordinate (r) in the linear equation r = -2.5t, where t is a negative number, will be located in the third quadrant. In the Cartesian coordinate system, the third quadrant is the region where both the x and y coordinates are negative.
In the given linear equation, r = -2.5t, the coefficient -2.5 indicates that the value of r is determined by multiplying a negative value of t by -2.5. Since t is restricted to negative numbers, it means that as t decreases in magnitude (moving towards more negative values), the value of r increases in magnitude but remains negative. Therefore, the resulting coordinates (r, t) will lie in the third quadrant.
To visualize this, imagine a graph with t as the x-axis and r as the y-axis. As t moves towards more negative values, r moves towards more negative values as well. The line representing the equation r = -2.5t will extend downwards from the origin and fall entirely within the third quadrant. Thus, the coordinate (r) in this equation will be located in the third quadrant.
