Catherine invested a principal of $1,650 in her bank account with interest rate 3.1 % How much interest did she earn in 14 years

never [62]

Answer:

$693

Step-by-step explanation:

Catherine invested a principal of $1,650 in her bank account with;

interest rate of 3.1%

How much interest did she earn in 14 years?

To find the amount accumulated in the 14 years, we use the formula:

A = P(1 + rt)

Where A is the amount accumulated, P is the principal, r is the interest rate and t is the time.

A = $1650(1 + $\frac{3}{100}$ (14))

A = $1650 + $693 = $2343

Interest = Amount (A) - Principal (P) = $2343 - $1650 = $693

The function f(x)= square root of x is translated using the rule (x, y) → (x – 6, y + 9) to create A(x). Which expression descri

Alex73 [517]

The function $f(x)=\sqrt{x}$ is translated according to the rule

$(x,y)\rightarrow (x-6,y+9).$

This translation is translation 6 units to the left and 9 units up.

1. Translation of the function $f(x)=\sqrt{x}$ 6 units to the left gives you the function $g(x)=\sqrt{x+6}.$

2. Translation of the function $g(x)=\sqrt{x+6}$ 9 units up gives you the function $A(x)=\sqrt{x+6}+9.$

The domain of the function $A(x)$ is $[-6,\infty),$ then the range of the function $A(x)$ is $[9,\infty).$

Answer: $[9,\infty).$

If sin 0 = 15/17 use pythagorean identity to find cos 0

Inga [223]

Hello :
sin<span>θ = 15/17
</span> use pythagorean identity : cos²θ +sin² θ = 1
cos²θ = 1 - sin² θ
cos²θ = 1-(15/17)²
cos²θ = 1- 225/289
cos²θ = 64/289
cos²θ = (8/17)²
cosθ = 8/17 or -8/17
