Answer:

$12089.26

Step-by-step explanation:

10,000

1.024 (100% of 10,000 + 2.4%)

1.024 * 10,000 = 10240 (1 year)

1.024 * 10240 = 10485.76 (2 years)

1.024 * 10737.42 = 10995.12 (3 years)

1.024 * 10995.12 = 11259 (4 years)

1.024 * 11259 = 11529.22 (5 years)

1.024 * 11529.22 = 11805.92 (6 years)

1.024 * 11805.92 = 12089.26 (7 years)

t = 11 years

Step-by-step explanation:

First, convert R as a percent to r as a decimal

r = R/100

r = 9/100

r = 0.09 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(14,382.05/5,403.00) / ( 4 × [ln(1 + 0.09/4)] )

t = ln(14,382.05/5,403.00) / ( 4 × [ln(1 + 0.0225)] )

t = 11 years

Summary:

The time required to get a total amount of $14,382.05 with compoundeded interest on a principal of $5,403.00 at an interest rate of 9% per year and compounded 4 times per year is 11 years.

inequality form: x [tex]\leq[/tex] -2 or x > 3

interval notation form: (-∞,-2] ∪ (3,∞)

Step-by-step explanation:

I attached a picture that shows all the work. You begin by isolating then solving for x on both sides. Then form a solution using the information found out about x. For example, you can combine the found inequalities for x to solve that x must be GREATER than 3 while being LESS than -2. Using that you can form an line and make a line. Remember, when writing in interval notation form you always begin from the left to the right (in reference) to the number line.

The value of z test statistics is 2.83.

Simply said, a z-score, also known as a standard score, informs you of how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.

You can plot a z-score on a normal distribution curve. The range of Z-scores ranges from -3 standard deviations (which would be on the far left of the normal distribution curve) to +3 standard deviations (which would fall to the far right of the normal distribution curve). You must be aware of the mean and population standard deviation in order to use a z-score.

Given mean = x = 36.1 inches

standard deviation = σ = 0.3

sample size = n = 72

and μ = 36.1

here z = (x - μ)/(σ/[tex]n^{1/2}[/tex])

z = (36.1 - 36 )(0.3/[tex]72^{1/2}[/tex])

z = 0.1/0.0354

z = 2.8248

z = 2.83

Hence the value of z test is 2.83.

Since a fraction is a division problem, you can do every answer and compare them until you get them in order, which D is the most reliable.

The law of cosine helps us to know the third side of a triangle. The value of third side c is 20.87.

The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,

[tex]c =\sqrt{a^2 + b^2 -2ab\cdot Cos\theta}[/tex]

where

c is the third side of the triangle

a and b are the other two sides of the triangle,

and θ is the angle opposite to the third side, therefore, opposite to side c.

Given, in ΔABC, a = 32, b = 21 and the angle between a and b is 40°, therefore, the value of ∠C=40°.

Now, the value of the third side of the triangle using the cosine law can be written,

[tex]c=\sqrt{a^{2}+b^{2}-2 a b \cdot \cos \gamma}\\\\c=\sqrt{32^{2}+21^{2}-2(32 \times 21)\cdot \cos 40^o}\\\\c=\sqrt{1,024+441-1,029.5637}\\\\c=20.867 \approx 20.87[/tex]

Hence, the value of third side c is 20.87.

Answer: Choice C

Vertex = (5, -2)

===============================================

Explanation:

Vertex form is [tex]y = a(x-h)^2 + k[/tex] where the vertex itself is located at (h,k)

As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.

In the case of choice C, we have [tex]y= \frac{1}{2}(x-5)^2 - 2[/tex] which is the same as [tex]y = \frac{1}{2}(x-5)^2 + (-2)[/tex] and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)

Answer:

Step-by-step explanation:

There are 3 triangles in the picture: the one on the left, the one on the right, and the overall triangle. We must first find the areas of the two smaller triangles before finding the area of the whole thing.

To find the area of a triangle, you must multiply the two legs of the triangle by each other and then divide that number by 2. For the left triangle, this would be [tex](4*4)/2=8[/tex], meaning it has an area of 8 square meters. For the right triangle, this would be [tex](4*3)/2=6[/tex], meaning the triangle on the right has an area of 6 square meters.

There are multiple ways to find the area of the big triangle, since the hypotenuse of the left triangle has been rounded. One way to find the area of the big triangle,is to add the areas of the two smaller triangles: [tex]8+6=14[/tex] square meters. For a more exact answer, we would solve [tex](5.7*5)/2=14.25[/tex]sqaure meters using the legs of the big triangle.

Hope this helps! :)
