$77 at 16% for 6 months
What is the difference between the total amount in the account if you did simple and compound interest?
Answer:
$0.231
Step-by-step explanation:
Given data
P= $77
r= 16%
t= 6 months= 0.5 years
For simple interest
A= P(1+rt)
A=77(1+0.16*0.5)
A= 77(1+0.08)
A= 77*1.08
A= $83.16
For compound interest
A=P(1+r)^t
A= 77(1+0.16)^0.5
A= 77(1.16)^0.5
A= 77*1.077
A= $82.929
The difference is
=83.16- 82.929
=$0.231

Power is the result of multiplying two numbers together. The correct option is 2×2×2×2×2×2, 4×16, and 8×8.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The given expression can be written as,
2⁶ = 2 × 2 × 2 × 2 × 2 × 2
= 4 × 16
= 8 × 8
Hence, the correct option are 2×2×2×2×2×2, 4×16, and 8×8.

I'm stuck on a math question. "A submarine is descending to examine the seafloor 2100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarines elevation and time."
Answer:
-1,050
Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.
Answer:
The answer is -1,050.
Step-by-step explanation:
An equation to represent the relationship between the submarines elevation & time would be y=-1,050x. Since we know that in two hours the submarine can reach 2,100 feet below the surface we need to figure out how long the submarine can reach in 1 hour. So we do 2,100/2 which equals 1,050. And since the submarine going below, it turns into -1,050.

Choose the missing step in the given solution to the inequality −2x − 14 > −4 + 3x.
−2x − 14 > −4 + 3x
−5x − 14 > −4
_____________
x < −2
A. −5x < 10
B. −5x > −18
C. −5x > 18
D. −5x > 10
Answer:
Step-by-step explanation:
-2x - 14 > -4 + 3x
subtract 3x from both sides
-5x - 14 > -4
add 14 to both sides
-5x > 10
divide both sides by -5
x < -2
The answer would be -5x > 10.
This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.
So therefore the answer would be -5x > 10.

Abigail's grandmother gave her a square shaped quilt that was made up of 256 small squares. How many squares are on each side of the quilt?
Answer:
64
Step-by-step explanation:
you divide 256 four times
a) 25.8
b) 36.8
c) 64.2
d) 42.0
Answer:
y = 25.8
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos y = adjacent/ hypotenuse
cos y = 18/20
Take the inverse cos of each side
cos ^-1 (cos y) = cos^-1(18/20)
y =25.84193276
Rounding to the nearest tenth
y = 25.8
Verify Euler's formula for
(a) Tetrahedron
(b) Hexagonal prism
Answer:
Euler's formula for polyhedron is:
V - E + F = 2where V- vertex, E- edge, F- faceAs per the above formula the relationship between the vertexes, edges and faces is same for any polyhedron.
Lets confirm, have a look at the picture
(a) Tetrahedron, count each element:
V = 5, E = 8, F = 5Verify
5 - 8 + 5 = 10 - 8 = 2 - correct(b) Hexagonal prism, count each element:
V = 12, E = 18, F = 8Verify
12 - 18 + 8 = 20 - 18 = 2 - correctThe semi-circle has a diameter of 8. What is the perimeter of the semi-circle?
Answer:
roughly 12.56 units
Step-by-step explanation:
Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle
half of the diameter is the radius, so 8/2 =4, r=4
Plug in what we know...
C=2*pi*4
Solve
2*3.14*4
25.12
divide by 2
25.12/2=12.56
12.56 units is the perimeter
Answer:
Approx. 20.566 units
Step-by-step explanation:
Find the circumference of the whole circle first by doing:
C = 2πr
r = 4 (8 divided by 2)
C ≈ 25.133
Then divide that by two because a semi-circle is half a circle:
12.566
Then add 8 (diameter) to that number for the open side.

Answer:
1) Zero based on (-16·t - 2) is t = -1/8 second
2) Zero based on (t - 1) is t = 1 second
Step-by-step explanation:
The given functions representing the height of the beach ball the child throws as a function of time are;
y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2
We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero
In the function of the question, we have;
y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The above equation can be written as follows;
y = (-16·t - 2) × (t - 1)
Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0
1) The zero based on (-16·t - 2) = 0, is given as follows;
(-16·t - 2) = 0
∴ t = 2/(-16) = -1/8
t = -1/8 second
The zero based on (-16·t - 2) is t = -1/8 second
2) The zero based on (t - 1) = 0, is given as follows;
(t - 1) = 0
∴ t = 1 second
The zero based on (t - 1) is t = 1 second

so 8*6=48, so we know that (4*6)+(_*6) should equal 48.
4*6=24
subtract 24 by 48 and we get 24.
now you probably know that it equals 4, but to be sure, divide 24 by 6, and you'll get 4.

So, based on my knowledge, you are learning the Distributive probability. So, what the Distributive property does is it basically allows to distribute the one of the numbers in the multiplication problem. In this problem, we can see that the 8 is being distributed into two groups of 4 to make (4 * 6) + (4 * 6). Then, we solve the things in the two parenthesis, making 24 + 24. Now, all we have to do is add 24 + 24, making 48.
