Answer:

I’m not sure what the question is since you are just giving me the information, but I’m gonna tell you this:

History >> 2 hrs

Chem >> 30 mins

Alg 2 >> 1 hr 30 mins

Hope this helps!

__________________________________

Step-by-step explanation:

4 hours << total

Half her time on history>>4/2>>2 hrs on history

Leftover time>>4-2=2 hrs left

A fourth of leftover time on chem>>2hrs/4 = 30 mins on chem

What’s left? 2hrs - 30 mins= 1hr and 30 mins << leftover <<alg 2

A baseball is thrown with an upward velocity of 32 feet per second. The equation h=-16t^2+32t gives the height of the ball t sec
AnnZ [28]

Answer:

The function of height has a maximum value.

Step-by-step explanation:

Maximum or Minimum:

A given function f(x).

  1. Find out f'(x) and f''(x)
  2. Then set f'(x)=0 which gives x=a.
  3. f''(a) > 0 , then at x=a , f(x) has minimum value.
  4. If f''(a)<0 , then at x=a, f(x) has maximum value.

Given that, a baseball is thrown with with an velocity of 32 feet per second.

The equation of height is

h=-16t^2+32t

Differentiating with respect to t

h'=-32 t+32

Again differentiating with respect to t

h''=-32

Next, we set h'=0

-32 t+32=0

\Rightarrow 32t=32

\Rightarrow t=1

Now h''|_{t=1}=-32

Since at t=1, h''<0.

The function of height has a maximum value.

The maximum of h is = -16.(1)²+32

                                     = -16+32

                                     =16 feet

I would appreciate if you helped me
Alona [7]

Answer:

The third option

Step-by-step explanation:

First, write the equation out as 700(0.25)=x and 700-x=y (y being your final answer). 700*0.25 is 175. Now, we subtract 175 from 700. 700-175 is 525. $525 is your final answer, which makes the third option correct. Hope this helps!

Consider the equations 4(x-3)=16 and 4x-3=16 do they have the same solution? Why or why not ?
Sladkaya [172]

Answer: Both the equations when solved have different answers, the solutions for both the equation are given below. In the the first equation  4 (x-3)=16 , 4 is multiplied with both the terms in the bracket. Whereas, in the second equation 4x- 2 = 16  there is no variable to multiply with the LHS equation

Solution:

4 (x-3)=16

4x - 12 = 16

4x = 16 + 12

4x = 28

x = 7


4x - 3 = 16

4x = 16 + 3

4x = 19

x = 19/4

x = 4.75
