Which expression is equivalent to the expression below?
Answer:
C. [tex]\dfrac{1}{(m-4)(m-3)}[/tex]
Step-by-step explanation:
First note that
[tex]m^2-16=(m+4)(m-4) \quad \text {and} \quad m^2-9=(m+3)(m-3)[/tex]
On the other hand, the expression from the question is equivalent to
[tex]\dfrac{m+3}{m^2-16} \cdot \dfrac{m+4}{m^2-9}=\dfrac{m+3}{(m+4)(m-4)}\dfrac{m+4}{(m+3)(m-3)}[/tex]
we cancel the equal terms in the numerator and the denominator and finally we get that our expression is equivalent to
[tex]\dfrac{1}{(m-4)(m-3)}[/tex]

What is 1 17/24 simplified
1(17/24) simplified is 41/24.
We have,
To simplify the mixed number 1 17/24, we need to convert it to an improper fraction.
To do that, we multiply the whole number (1) by the denominator of the fraction (24), and then add the numerator (17):
1 x 24 + 17 = 24 + 17 = 41
So, the mixed number 1 17/24 is equivalent to the improper fraction 41/24.
Therefore,
1(17/24) simplified is 41/24.

What is a perfect square?Perfect squares are those integers whose square root is an integer.
Let x-a be the closest perfect square less than x,
and let x+b be the closest perfect square more than x, then we get x-a < x < x+b (no perfect square in between x-a and x+b, except possibly x itself).
Then, we get:
[tex]\sqrt{x-a} < \sqrt{x} < \sqrt{x+b}[/tex]
[tex]\sqrt{2x+1}+3 = 0\\\\\sqrt{2x+1}= -3[/tex]
by taking square on both sides we get

Myron put $5000 in a 2-year CD paying 3% interest, compounded monthly. After 2 years, he withdrew all his money. What was the amount of the withdrawal?
Answer:
$5308.79
Step-by-step explanation:
The future value can be computed from ...
FV = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual interest rate, n is the number of times per year it is compounded, and t is the number of years.
You have P = $5000, r = 0.03, n = 12 (months per year), t = 2.
Filling in the given numbers, we have ...
FV = $5000(1 +.03/12)^(12·2) ≈ $5000(1.0617570) ≈ $5308.79
The amount of the withdrawal will be $5308.79.
Final answer:
To find the withdrawal amount for Myron's CD, the compound interest formula is used with the respective values plugged in. After 2 years, with 3% interest compounded monthly on a principal of $5000, the withdrawal amount is approximately $5,304.91.
Explanation:
The question deals with the calculation of compound interest for a Certificate of Deposit (CD), specifically with different compounding periods.
To calculate the withdrawal amount for Myron's 2-year CD with a principal amount of $5000 at a 3% interest rate compounded monthly, the formula for compound interest is:
[tex]A = P (1 + r/n)^{nt[/tex]
Where:
A = the amount of money accumulated after n years, including interest.P = the principal amount (initial deposit).r = the annual interest rate (decimal).n = the number of times that interest is compounded per year.t = the time the money is invested for in years.By plugging in Myron's values, we get:
[tex]A = $5000 (1 + 0.03/12)^{12\times 2[/tex]
Calculating this we find that A, the withdrawal amount, is approximately $5,304.91.

Which rule describes the translation? T–3, –2(x, y) T–3, 2(x, y) T3, –2(x, y) T3, 2(x, y)
SOMEONE PLEASE ANSWER PLEASE
The rule which describes the translation of the figure is T–3, –2(x, y).
The translation T(x, y) → (x – h, y – k) moves a point (x, y) to a new point (x – h, y – k).
T–3, –2(x, y) moves the point 3 units to the right and 2 units down.
T–3, 2(x, y) moves the point 3 units to the right and 2 units up.
T3, –2(x, y) moves the point 3 units to the left and 2 units down.
T3, 2(x, y) moves the point 3 units to the left and 2 units up.
So the answer is T–3, –2(x, y).
Here is a table that shows the effect of each translation on the point (3, 4):
Original point | Translation | New point

The difference of the squares of two positive consecutive even integers is 76. find the integers. use the fact that, if x represents an even integer, then x+2 represents the next consecutive even integer.
The two positive consecutive even integers that, when their squares are subtracted, equal 76 are 18 and 20.
Explanation:In this problem, the two positive consecutive even integers can be represented as x and x+2. The problem states that the difference of their squares is 76, which can be put into the equation (x + 2)^2 - x^2 = 76. By simplifying this equation, we get 4x + 4 = 76. Solving for x, we find that x = 18. Therefore, the two consecutive even integers are 18 and 20.

Identify each pair of equal angles as vertical angles, corresponding angles, alternate interior angles, or alternate exterior angles.
m<3 = m<7:
m<1 = m<4:
m<5 = m<8:
m<1 = m<5:
m<1 = m<8:
m<2 = m<6:
m<2 = m<3:
m<4 = m<8:
m<6 = m<7:
m<3 = m<6:
m<2 = m<7:
m<4 = m<5:
Answer:
Vertical angles : Opposite angles made by two intersecting lines.
Corresponding angles : which occupy the same relative position at each intersection where a straight line crosses two others.
Alternate interior angles : when a transversal passes through two line then the angles that are formed on opposite sides of the transversal and inside the two lines.
Alternate exterior angles : angles on the outer side of each of those two lines but on opposite sides of the transversal.
Here, line k passes through the lines p and q,
Thus, by the above explanation,
Vertical pairs are, angle 1 and angle 4, angle 2 and 3, angle 5 and angle 8, angle 6 and 7,
Corresponding pairs,
angle 2 and angle 6, angle 1 and angle 5, angle 4 and angle 8, angle 3 and angle 7,
Alternate interior angles pair,
angle 4 and angle 5, angle 6 and angle 3,
Alternate exterior angles pair,
angle 2 and angle 8, angle 1 and angle 7,
Vertical angles are always equal in measure,
Now, the p and q are parallel lines,
So, the corresponding angles will be congruent as well as alternative interior or exterior will be congruent.
Therefore, the required pair,
Corresponding pairs :
m∠1=m∠5
m∠2=m∠6
Alternative interior pairs :
m∠3=m∠6
m∠4=m∠5,
Alternate exterior pairs :
m∠1=m∠8
m∠2=m∠7
Vertical pairs :
m∠1=m∠4
m∠5=m∠8
m∠2=m∠3
m∠6=m∠7
