For this problem, we will use the first method. The numerator can be factored by grouping as follows. In a right triangle, the cosine function is cos? A baseball is thrown up in the air from an initial height of 6 feet. D To simplify the expression, first factor the numerator and the denominator. . Solve the inequality for x. D You can solve this problem either 1 by simplifying the numerator and denominator separately and then simplifying the result or 2 by using the distributive property.
Therefore, we need to set the given function equal to zero. Factor this expression out and then use trial-and-error to factor the resulting trinomial. D The baseball will hit the ground when its height is zero. Therefore, you can further simplify the expression by cancelling it out. Therefore, you can further simplify the expression by cancelling it out.
By the trial-and-error method, the numerator can be factored into two binomials as follows. C Use a unit circle to model the value of cosine. Factor the left side and use the zero-product property to solve for t. Solve the equation for x. C nly: The logarithm of a number is the exponent that the base must to be raised to in order to get that number. A and C To solve, first factor the polynomial. Therefore, to find f x , substitute 2-3i and 2+3i for a and b into this equation and simplify the result.
Then use these values to calculate the average rate of change. For this problem, we will use -5, -1, 1, and 2 as test numbers. How long will it take in seconds for the baseball to hit the ground? Thus, the calculator will hit the ground 3 seconds after it is thrown. D To simplify the expression, first factor the numerator and the denominator. Substitute these values into the original polynomial. Check this value on your own by substituting it into the original equation to make sure that the result is a true statement.
B All of the choices involve two transformations of the given expression: factoring out either 2 or 2x and changing the radical to an exponent. These values divide the number line into four intervals. Choose a test number from each interval and determine whether the product is positive or negative. . . . .
