What are the possible values for x in the equation 4x^2=64

Mathematics
2 answers:
Degger [83]3 years ago
4 0

                                  <u> 4 x²  =  64</u>

Divide each side by  4 :     x² = 16

Take the square root
of each side:                     x = √16

                                   x = <em>+ 4</em>
and
                                   x = <em>- 4</em> .

Verify the identity:<br> tan(x+pi/2)=-cotx<br><br> please!!
olya-2409 [2.1K]
First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb

tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx, 
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx, 
</span> because <span>cospi/2 =0,  </span>and <span>sinpi/2=1

</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>

What is the multiplicative rate of change for the exponential function graphed to the left?
schepotkina [342]

Answer:

The multiplicative rate of change is 3

Step-by-step explanation:

The given graph passes through the points:

(-2,\frac{2}{9}),(-1,\frac{2}{3}),(0,2),(1,6),(2,18),(3,54)

The multiplicative rate of change is the factor that multiplies each y-value to give the subsequent y-values.

We can find that factor by dividing a y-value by the previous y-value of any two consecutive y-value.

The multiplicative rate of change is \frac{6}{2}=3 or \frac{18}{6}=3 or \frac{54}{18}=3  or \frac{2}{\frac{2}{3} } =3.

The height H of a skydiver t seconds after jumping. Let T be the independent variable, and assume the skydiver jumps from a heig
Rina8888 [55]

Answer:

25 seconds

Step-by-step explanation:

Skydiving.  

height (in feet) above the earth=h(t)= -16t^2 + 10,000

the time it would take to fall when h is 0  

-16t^2 + 10,000=0

-16t^2=-10000

16t^2=10000

t^2=10000/16=625

t=sqrt 625=25 seconds
