(2 points) A 18-foot support post leans against a wall, making a 53° angle with the ground. Tyler and Janae was instructed to find how high off the ground the support post will reach? Tyler wrote the equation cos 37=x18, while Janae wrote sin 53=x18 . Are both students’ equations correct? Explain why?

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Which is the solution to the inequality? 2 3/52 1/15 b< 3 2/15 b> 3 2/15
