The figure below shows parallel lines cut by a transversal: a pair of parallel lines is shown with arrowheads on each end. a transversal cuts through these two lines. an angle formed between the top parallel line and the transversal on the inner left side is marked 1. another angle formed between the bottom parallel line and the transversal on the inner right side is marked 2. which statement is true about ∠1 and ∠2? ∠1 and ∠2 are congruent because they are a pair of adjacent angles. ∠1 and ∠2 are complementary because they are a pair of adjacent angles. ∠1 and ∠2 are congruent because they are a pair of alternate interior angles. ∠1 and ∠2 are complementary because they are a pair of alternate interior angles.

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60

Which of the following is true for the relation f(x)=2x^2+1

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
