You have $550 in a savings account that earns 3% simple interest each yaer. How much will be in your account in 10 years?
bija089 [108]
Looking at the given question, we can find several important information's and based on thm we can easily calculate the amount after 10 years.
Principal amount = $550
Rate of interest per year = 3%
Number of years the amount is to be kept = 10 years
Now we get put these information's in the formula of finding amount of money kepy in simple interest.
Amount = P(1 + rt)
Where
p = principal amount
r = rate of interest
t = Time
Then
Amount = 550[1 + (3/100) * 10)]
             = 550 [1 + 3/10]
             = 550 * (13/10)
             =  55 * 13
             = 715 dollars
So the total amount in my account will be $715

Use the graphs to estimate both solutions to x^2+x-4=0
Bogdan [553]

Answer:

No graph so we'll use the quadratic formula

x^2+x-4=0

a = 1

b = 1

c = -4

x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2

x = (-1 +- sqr root (1 +16) ) / 2

x1 = (-1 + sqr root (17)) / 2

x2 = (-1 - sqr root (17)) / 2

If f(x)= 10 sin(x) – 3 then f (30%) = ?
marissa [1.9K]

Answer:

The value of f(30) is equal to 2.

Step-by-step explanation:

The given expression is :

f(x)= 10 \sin(x) - 3

We need to find the value of f(30)

Put x = 30 in above expression.

So,

f(x)= 10 \sin(30) - 3\\\\=10\times \dfrac{1}{2}-3\\\\=5-3\\\\=2

Hence, the value of f(30) is equal to 2.

5:3 equivalent fraction
lana66690 [7]

Answer:

5/3

Step-by-step explanation:

A ratio is just a fraction comparing two quantities.

Ex: For every 5 trees, there were 3 elephants

This, into a fraction, would take the first number and make it the numerator and the second number into a the denominator.

Just think of the colon as a slash or a divide sign
