Find the balance at the end of 4 years if $10,000 is deposited at a rate of 1.5% simple interest.
Minchanka [31]

Answer:

Principal amount (P) = $10,000

Rate (R) = 1.5%

Time (T) = 4 years

Simple interest, I = P X R X T / 100

= 10000 X 1.5 X 4 /100

= 60000 / 100

= $600

Therefore, Balance = P + I

= 10000 + 600

= $10600

To determine how a city’s residents feel about building a new youth center, a group considers surveying 50 random children at a
Lemur [1.5K]
This would result in a biased sample because:

- the survey is surveying elementary kids about a new youth center

most of those kids are more likely than not to want a youth center, so most of them will naturally agree without a doubt for the need of a youth center

- Even the adults at the elementary school are more likely than not to agree with a new youth center because they are teachers and can even benefit from working at the youth center

- in final words the reason why this survey will be biased is because there is no variety in the participants being tested. It is basically just asking teachers she students their preference, excluding the rest of an entire community

please vote my answer brainliest. thanks!

An isosceles triangle’s altitude will bisect its base. Which expression could be used to find the area of the isosceles triangle
omeli [17]

Answer:

\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}

Step-by-step explanation:

The length of the base is the distance between the points 4+2i and 10+4i, so

\text{Base}=|10+4i-(4+2i)|=|10+4i-4-2i|=|6+2i|=\sqrt{6^2+2^2}=\\ \\=\sqrt{36+4}=\sqrt{40}

The middle point of the base is placed at point

\dfrac{4+2i+10+4i}{2}=\dfrac{6i+14}{2}=7+3i

The length of the height is the distance between the points 5+9i and 7+3i

\text{Height}=|5+9i-(7+3i)|=|5+9i-7-3i|=|-2+6i|=\sqrt{(-2)^2+6^2}=\\ \\=\sqrt{4+36}=\sqrt{40}

So, the area of the triangle is

A=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}=\dfrac{\sqrt{40}\cdot \sqrt{40}}{2}
