If you deposit $3,000 at 2.5% compounded continuously, what would your ending balance after 4 years?
You will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.
What is continuous compound interest?
In theory, continuously compounded interest means that an account balance is constantly earning interest, as well as refeeding that interest back into the balance so that it, too, earns interest.
The formula for continuously compounded interest is:
[tex]A = P * e^{rt}[/tex]
where:
A is the ending balance (the amount you will have after 4 years)
P is the principal (the initial amount you deposited, in this case $3,000)
r is the interest rate (2.5% per year, or 0.025)
t is the time in years (4 years)
Plugging these values into the formula, we get:
[tex]A = $3,000 * e^{(0.025 * 4)}[/tex]
Calculating this gives us an ending balance of $3,276.44.
Hence, you will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.

asmita went to a blackjack table at the casino. at the table, the dealer has just shuffled a standard deck of 52 cards. asmita has had good luck at blackjack in the past, and she actually got three blackjacks with aces in a row the last time she played. because of this lucky run, asmita thinks that ace is the luckiest card. the dealer deals the first card to her. in a split second, she can see that it is a non-face card, but she is unsure if it is an ace. what is the probability of the card being an ace, given that it is a non-face card? answer choices are in a percentage format, rounded to the nearest whole number.
The probability of the card being an ace, given that it is a non-face card will be 0.1 or 10%
There are total 52 cards.
Out of 52, 26 are red and 26 are black.
Each of the four French suits—clubs (♣), diamonds (♦), hearts (♥) and spades (♠).—has 13 ranks in a regular 52-card deck. King, Queen, and Jack are the three court cards (face cards) in each suit, and their pictures are reversed (double-headed). The ten numerical cards, or pip cards, in each suit range in value from one to 10.
Out of 52 cards, (Kings, Queen, Ace) are faced card.
And each set of cards have 4 different colour and shades.
So, total number of faced card will be = 4*3 = 12
So, total number of not a faced card = 52-12 = 40
So, the value of P (It is an ace and it is not a face card) =4/52
So, the value of P(It is not a face card)=40/50
[tex]P\left(\frac{\text { It is a ace }}{\text { It is not a face curd }}\right) =\frac{P(\text { It is an ace and it is not aface carl) }}{P(\text { It is not a face card) }} \\\\ =\frac{\frac{4}{52}}{\frac{40}{52}}\\\\=\frac{4}{40}\\\\=0.1=10\% }[/tex]

x² - 2px + p² = q
x² - 2px + p² - q = 0
our target is
x² + 4x - 20 = -8
x² + 4x - 12 = 0
now we compare the variable expression with the target.
x² = x² check
4x = -2px

p = -2
-12 = p² - q = 4 - q
-16 = -q
q = 16

Two triangles each have an angle measuring 15 degrees. The first triangle also has an angle
measuring 20 degrees.
The second triangle must have an angle of which measure if the two triangles are similar?
The measure of the third angle = 105°.
What is angles?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
The sum of the angles in a triangle is :
A° + B° + C° = 180°
Where A, B and C are the three angles in a triangle.
Hence, if two of the angles are given as : 55° and 20°
The measure of the third angle will be :
Let the measure of the third angle = C
(55 + 25 + C) = 180°
180° - (55° + 20°)
180° - 75° = 105°

Other geometries, including spherical, elliptic, and hyperbolic, with opposite sides of equal length and equal angles that are not right angles.
Area =Area of the down rectangle+ Area of the up rectangle+2×Area of the triangle
Area= (7×24)+(4×13)+2×(1/2)×b×4
Let, 13+2x=24
Here, x=b
So, 2b=11
b=11/2
Area= 168+52+4(11/2)
Area=168+52+22
Area=242in²
Therefore, the area of the composite figure is 242in².
So, option C is correct.
