You deposit $2,400 in an account that earns 1.9% annual interest. Find
the balance after 3 years if the interest is compounded monthly.
Remember this is $ so you round to 2 decimal places unless told to do
differently.
Answer:
$2471.53
Step-by-step explanation:
Use the compound amount formula:
A = P(1 + r/n)^(nt), where n is the number of compoundings per year
Here,
A = ($2,400)(1 + 0.019/12)^(12·3), or
($2,400)(1.0015)^36
= ($2,400)(1.026) =
= $2471.53

Simplify the expression and then substitute the given number for the variable. For expression 8a2+6b+9a2+9b2+3b, find the value if a=2,b=−1.
Answer: 68
Step-by-step explanation:
Simplifying the expression:
= 8a² + 6b + 9a² + 9b² + 3b
Collect like terms
= 8a² + 9a² + 6b + 3b + 9b²
= 17a² + 9b + 9b²
We then substitute a=2,b=−1.
= 17a² + 9b + 9b²
= 17(2)² + 9(-1) + 9(-1)²
= 68 -9 + 9
= 68
Help me with this 1,2,3. For each sequence, Determine with whether it appears to be arithmetic If it does find a common difference
Problem 1
Answer: Arithmetic, common difference = -4-------------------
Explanation:
Pick any term of the sequence, and subtract off the previous term to find that,
term2 - term1 = -12 - (-8) = -12 + 8 = -4term3 - term2 = -16 - (-12) = -16 + 12 = -4term4 - term3 = -20 - (-16) = -20 + 16 = -4Each time we get the same result, so that means we have an arithmetic sequence with common difference -4
This indicates that adding -4 to each term, or subtracting 4 from each term, will generate the next one.
Eg: term2 = term1 - 4 = -8-4 = -12.
==========================================================
Problem 2
Answer: Arithmetic, common difference = 5-------------------
Explanation:
Similar to problem 1, this sequence is also arithmetic because we add on 5 to each term to get the next one
-6+5 = -1-1+5 = 44+5 = 9Or you could subtract adjacent terms as done in problem 1, to find that the common difference is 5.
==========================================================
Problem 3
Answer: Not arithmetic-------------------
Explanation:
Unlike the previous two problems, this sequence is not arithmetic.
We can see that
term2 - term1 = 12 - 3 = 9term3 - term2 = 48 - 12 = 36The gaps of 9 and 36 aren't the same. We need the same common difference between any adjacent terms to have an arithmetic sequence.
This sequence is instead geometric because
term2/term1 = 12/3 = 4term3/term2 = 48/12 = 4term4/term3 = 192/48 = 4Each quotient is 4, showing the common ratio is 4. To find the next term, we multiply the current term by 4. So the next term after 192 would be 4*192 = 768, then 4*768 = 3072 is next, and so on.

Determine the component form of the vector which has a magnitude of 30 & a direction of 116 degrees.
Given :
Magnitude of vector is 30 units.
Direction of vector from x-axis is 116°.
To Find :
The component form of the vector.
Solution :
We know, vector in component form is given by :
[tex]\vec{v} = (Acos\ \theta) \hat{i} + (Asin\ \theta)\hat{j}[/tex]
Putting given values,
[tex]\vec{v} = (30\times cos\ 116^o) \hat{i} + (30\times sin\ 116^o)\hat{j}\\\\\vec{v} = -13.15 \hat{i} + 0.90 \hat{j}[/tex]
Hence, this is the required solution.

1) Javier wants to replace the carpet in the two
bedrooms of his home. Bedroom 1: is rectangular
in shape that has a width of 10ft and length of
8.5ft. Bedroom 2: is rectangular in shape that has
a width of 11.75ft and length of 13.25ft. If the
carpet he wants to buy is $2.83 per square foot,
then how much will it cost for both rooms?
a. $85.00
b. $155.69
c. $240.69
d. $681.15
Answer:
d. $681.15
Step-by-step explanation:
Bedroom 1:
Width = 10 ft
Length = 8.5 ft
Area of bedroom 1 = length × width
= 10 ft × 8.5 ft
= 85 ft²
Bedroom 2:
Width = 11.75 ft
Length = 13.25 ft
Area of bedroom 2 = length × width
= 11.75 ft × 13.25 ft
= 155.6875 ft²
Total carpet in the two bedrooms = 85 ft² + 155.6875 ft²
= 240.6875 ft²
If the
carpet he wants to buy is $2.83 per square foot, then how much will it cost for both rooms?
Total cost for both rooms = Total carpet in the two bedrooms × cost per square foot
= 240.6875 ft² × $2.83
= $681.145625
Approximately $681.15
How do you find the distance between points (5,1), (4,0)?
Answer:
To find the hypotenuse, you would use the formula a^2 + B^2 = C^2
That is the formula for the pythagorean theorem.
I suggest you first plot it on a graph, then could the units on the sides that make up the legs.
When you plot it, the legs are both 1 unit.
so it would be, following the formula:
1^2 + 1^2 = c^2
1 x 1 + 1 x 1 = c^2
2 = c^2
Then you square root:
√2 = √c^2
1.41421356 = c
1.41421356 rounded to the nearest tenth is 1.4.
So the length of (5,1), (4,0) is ≈1.4
To approach the runway, a pilot of a small plane must begin at 6 degrees,descent starting from a height of 1905 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach
Answer:
C. 3.5 mi
Step-by-step explanation:
Reference angle = angle of elevation
Angle of elevation = angle of depression = 6° (alternate angle theorem)
Hypotenuse = x
Opposite = 1905 ft
Apply trigonometric function SOH:
Sin 6° = Opp/Hyp
Sin 6° = 1905/x
x * Sin 6° = 1905
x = 1905/Sin 6°
x = 18,224.7 ft
Convert form feet to miles
1 mi = 5,280 ft
Therefore,
18,224.7 = 18,224.7/5,280
= 3.45164773 mi
≈ 3.5 mi (nearest mile)
Find the probability that you roll the same number twice in a row when you toss two fair 6-sided dice.
Answer: 6/36
Step-by-step explanation:
When tossing two number cubes, you can get such sample space
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
There are 36 possible outcomes. Only (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6) use the same number twice.
Hence, the probability that you roll two numbers that are the same in a row is 6/36, or in simplified form, 1/6.

40°
[ ?
Answer:
14.6
Step-by-step explanation:
We solve using the Trigonometric function Cosine
cos θ = Adjacent/Hypotenuse
θ = 40°
Hypotenuse = 19
Adjacent = x
Therefore,
cos 40 = x/19
Cross Multiply
x = cos 40 × 19
x = 14.554844419
Approximately to the nearest tenth,
x = 14.6
The sum of twice a number and six is 14 find the number.
Let the number be x. So,

=> x = 4
So, the number is 4.
Answer:
Solution
here,given,
2x+6=14(let the unknown number be x)
or,2x=14-6
or,2x=8
or,x=8÷2
or,x=4
We know that,
x=4

(1, 3.5)
(9, -60.5)
(-8 -1)
(6, -30)
Answer: (6, -30)
Step-by-step explanation:
Substitute the points into the equation:
3.5 = -1/2(1^3) - 3(1) + 7 = 3.5: (1, 3.5) is on the graph.
-60.5 = -1/2 (9^2) -3(9) + 7 = -60.5: (9, -60.5) is on the graph.
-1 = -1/2 (-8^2) -3(-8) + 7 = -1. (-8, -1) is on the graph.
-30 = -1/2(6^2) -3(6) + 7 = -29 (6, -30) is not on the graoh.

A rectangular prism has a volume of 640 cubic centimeters, a height of 5 centimeters,
and a length of 8 centimeters. What is the width of the rectangular prism in centimeters?
Answer:
10 cm
Step-by-step explanation:
The volume of a rectangular prism is calculated by multiplying the length, width and height together. So, to find one of the dimensions, all we need to do is divide the volume by the given dimensions. In this case we divide the volume, 640, by the height, 5, and length, 8.
The width, or w, is equal to 640 divided by 5 and 8.
w = 640 ÷ 5 ÷8
w = 80 ÷ 8
w = 10
The width is 10 cm.

What is the length of segment GO
The length of the line segment GO is equal to the line segment HI. Then the length of line segment GO will be 25.3 inches.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries. A line segment is sometimes referred to as a section of a path that joins two places.
The length of segment HI is 25.3 inches. A reflection over the x-axis followed by a reflection over the y-axis can map it to segment GO.
The size of the line segment will not change when the reflection is taken over the x-axis and y-axis.
Thus, the length of the line segment GO is equal to the line segment HI. Then the length of line segment GO will be 25.3 inches.
