Answer:

5 groups of 5

Step-by-step explanation:

No. of students = 32
No. of students in each group = 5
No. of students  in ONE group = 7
No. of groups of 5 = 32 - 7
                               = 25
                               = 25/5 = 5

Which equations are true for x = –2 and x = 2? Check all that apply.
Katyanochek1 [597]

Hi Brainiac


x² - 4 = 0

Add 4 to both sides

x² - 4 + 4 = 0 + 4

x² = 4

Now take the square root

x= +/-√4

x= 2 or x= -2

The answer is A


I hope that's help :)

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

The crime rate of a certain city is increasing by exactly 6% each year. If there were 550
kap26 [50]

Using an exponential function, it is found that the approximate number of crimes in the year of 2016 was of 2502.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

In this problem, there were 550 crimes in the initial year observed, and the growth rate is of 6%, hence the parameters are A(0) = 550, r = 0.06, and the equation is given by:

A(t) = A(0)(1 + r)^t

A(t) = 550(1 + 0.06)^t

A(t) = 550(1.06)^t

2016 is 26 years after 1990, hence:

A(26) = 550(1.06)^{26} \approx 2502

The approximate number of crimes in the year of 2016 was of 2502.
