Landon is standing in a hole that is 5.1 ft deep. He throws a rock, and it goes up into the air, out of the hole, and then lands
kati45 [8]
This describes a parabolic path that starts at x=0 on a value of y = -5.1.  That's when the rock is below ground in the hole.  To find the answer we need to know the second x axis crossing.  The first is when it is rising and reaches ground level, the second is after it peaks and falls back to the ground and lands. Using the quadratic formula I get the two zeros of this function to be about
x= 15.29, and 66.71.  The rock then lands 66.71 feet from him horizontally.

Evaluate each expression for a=7,b=4,and c=-3.
stiks02 [169]

Answer:

Step-by-step explanation: 3a-5b= 3(7)-5(4)

                                                       =21-20

                                                       =<u>1</u>

7-3a+5a+15=7-3(7)+5(7)+15

                   =7-21+35+15

                   =-14+50

                   =<u>36</u>

15a^2-17(bc)^2=15(7)^2-17(4)(-3)^2

                         =105^2-204^2

                         =210-408

                         =<u>-198</u>

How do i do this cause im STRESSING TO THE MAX RIGHT NOW
ra1l [238]

Step-by-step explanation:

Something to remember is that, if a negative number has a large number in it (9, 10 etc.) instead of a smaller number (2, 3, etc.) then the greater number is actually smaller, because it is farther down on a number line.

1.) First, take -√9, and take away the - sign for a moment. Pretend it isn't negative.

2.) Next, find the square root of 9. What times what equals 9? 3x3=9, so √9=3.

3.) Now, place the negative sign back. So, this is -3.

4.) Now, take -2³. When there is a small number next to a normal number, that means that you need to multiply the large number by the small one. So, in this case, do 2x3.

5.) 2x3=6.

6.) Now, add the negative sign back to it. so, -6.

7.) Remember that if a negative number has a larger number, then it is actually smaller, as it is farther down on the number line.

8.) So, we have -3 and -6. Of course, -3 is larger. therefore, -2³ is less than -√9, and the answer is A.
