Simplify the expression. -5/8(-3/8-1/4)

prisoha [69]

Answer:

25/64

Step-by-step explanation:

To get this answer, first you need to use the distributive property:

(-3/8)(-5/8) - (1/4)(-5/8)

Next, multiply:

15/64 - (-5/32)

Change the negative signs into a positive sign:

15/64 + 5/32

Multiply 5/32 by 2 on both top and bottom:

15/64 + (5)(2)/(32)(2)

You will then get:

15/64 + 10/64

Now, add the numerators. You will get:

25/64

This is your answer. I hope it helped!

If g(x) = 3/2x + 3, and g(a) = 0, what is a ?

Lostsunrise [7]

Answer:

a = -2

Step-by-step explanation:

g(x) = 3/2x + 3

g(a) = 0

g(a) = 3/2a +3 =0

Subtract 3 from each side

3/2a +3-3=0-3

3/2a = -3

Multiply each side by 2/3

2/3 * 3/2a = -3*2/3

a = -2

During batting practice, two pop flies are hit from the same location, 2 s apart. The paths are modeled by the equations h = -16

drek231 [11]

9514 1404 393

Answer:

40.5 ft

Step-by-step explanation:

Solve for the time at which the balls meet, then find the corresponding height.

The balls will meet at the height such that the two values of h are the same.

-16t^2 +56t = h = -16t^2 +156t -248

0 = 100t -248

t = 2.48

Using the first equation to find h, we have ...

h = t(-16t +56) = 2.48(-16·2.48 +56) = 40.4736

The balls meet at a height of about 40.5 feet.
