(1 point) For each of the following, determine if substitution can be used to evaluate the integral. If so, fill in the substitution variable $w$ and the value of the integral; if not, enter na for both $w$ and the antiderivative. integral $ \int \frac{x^2}{(9+x^3)^4} dx = $ $ \int x^3 \cos(x^2) dx = $ $ \int \frac{x^3}{9+x^3} dx = $ $ \int x^2 \cos(x^3) dx = $ evaluates to w =

Texts: How is the 5.18% YTM calculated in Excel? Assume today is November 1, 2022, and that all bonds pay interest semi-annually with a face value of $1,000. YTM = Current yield + Capital Gains yield; CY = Annual Interest/Current Price. Apple is AA rated; AAA Treasuries yield 3-year is 4.50%, 10-year 4.30%. Two years ago, Apple issued 3.0% coupon-paying bonds with a face value of $1,000 set to mature on November 1, 2032. The bonds are callable in 1 year at 1050. Concerns over higher inflation have pushed interest rates higher globally.
