A worker is combining two chemicals used in a photography lab. Chemical R costs $0.17 per gram. Chemical T costs $0.32 per gram. The worker must make a batch of the two chemicals that costs less than $24.00. Which inequality models the situation, where is the number of grams of chemical R and is the number of grams of chemical T? will mark as brainliest!

Consider the function f left parenthesis x right parenthesis equals 4 x squared minus 3 x minus 1f(x)=4x2−3x−1 and complete parts (a) through (c). (a) find f left parenthesis a plus h right parenthesis f(a+h); (b) find startfraction f left parenthesis a plus h right parenthesis minus f left parenthesis a right parenthesis over h endfraction f(a+h)−f(a) h; (c) find the instantaneous rate of change of f when aequals=77.
