How many years will it take to double an investment at 11% simple interest? ​

Mathematics
1 answer:
ddd [48]3 years ago
7 0

Answer:

10 years

Step-by-step explanation:

We can use the equation for simple interest: <em>I = P(1 + (R*T))</em>, and change some of the numbers: <em>2P = P(1 + (0.11*T))</em>

Divide: <em>2 = 1 + (0.11*T)</em>

Subtract: <em>1 = 0.11*T</em>

Divide: <em>T = 100/11 ≈ 9.09</em> ⇒ 10 years (rounded up because it won't be doubled until the next year)

A ball is kicked from the ground with a velocity of 38.50 ft/sec at an angle of 35 degrees. How many feet will the ball travel h
anzhelika [568]

Answer:

Horizontal distance is 142.12 feet.

Step-by-step explanation:

We have,

Velocity of the ball is 38.50 ft/sec. The angle of projection of the ball is 35 degrees.

It is required to find the horizontal distance covered by it before it comes back to the ground on its first bounce. It means we need to find the horizontal range of the projectile. Range of a projectile is given by :

R=\dfrac{u^2\sin2\theta}{g}\\\\R=\dfrac{(38.5)^2\times \sin2(35)}{9.8}\\\\R=142.12\ ft

So, the horizontal distance covered by it before it comes back to the ground on its first bounce is 142.12 feet.

How can the order of operations be used to simplify expressions?
Lapatulllka [165]
Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.

This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc. 

The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.

Hope this helps, and I was the brainliest! :)
