1) 8v+w+7-8v+2w

=w+7+2w

=3w+7

-----------------------------

2) 4c^2+6c-3c^2-2c-3

=c^2+6c-2c-3

=c^2+4c-3

-------------------------------

3) z^3+5z+3z^2+1-4-2z^2

=z^3+z^2+5z+1-4

=z^3+z^2+5z-3

A fish swims over the waterfall. The distance y (in feet) that the fish falls is given by the function y=16t2 , where t is the t
inessss [21]

Answer:

See Explanation

Step-by-step explanation:

Given

y = 16t^2

The equation is incomplete. However, a possible question could be to calculate the distance of the fish at a particular time

e.g. Time, t = 4,

The distance is:

y = 16t^2

y = 16 * 4^2

y = 16 * 16

y = 256ft

Another possible question is to determine the time taken to cover a certain distance

e.g.

Distance, y = 400

This gives:

y = 16t^2

400 = 16t^2

Divide by 16

25 = t^2

Take square roots

5 = t

t = 5\ seconds

How do I find out if a function is in standard form
anzhelika [568]
Hey!

A function in slope-intercept form would look like y=mx+b; with the x and y values on the opposites of the equation.

A function in standard form would look like ax+by=c; with the x and y values on the same side of the equation.


Hope this helps!

Which measurement is closest to the measure of segment W Z?
noname [10]
Like XZ divides the cord YV into two congruent parts (YW=5.27 cm=WV), this segment XZ must be perpendicular to the segment YV, then the angle XWY in triangle XWY is a right angle (90°) and the triangle XWY is a right angle.

We can apply the trigonometric ratios in triangle XWY:
Hypotenure: XY
sin 44°=(Opposite leg to 44°)/(hypothenuse)
sin 44°=YW/XY
sin 44°=(5.27 cm)/XY
Solving for XY. Cross multiplication:
sin44° XY=5.27 cm
Dividing both sides of the equation by sin 44°:
sin 44° XY / sin 44° = (5.27 cm)/sin 44°
XY=(5.27/sin 44°) cm
XY=(5.27/0.694658370) cm
XY=7.586462929 cm

This value XY is the radius of the circle, then:
XZ=XY→XZ=7.586462969 cm

tan 44°=(Opposite leg to 44°) / (Adjacent leg to 44°)
tan 44°=YW/XW
tan 44°=(5.27 cm)/XW
Solving for XW. Cross multiplication:
tan 44° XW=5.27 cm
Dividing both sides of the equation by tan 44°:
tan 44° XW / tan 44°=(5.27 cm)/tan 44°
XW=(5.27/tan 44°) cm
XW=(5.27/0.965688775) cm
XW=5.457244753 cm

WZ=XZ-XW
WZ=7.586462969 cm-5.457244753 cm
WZ=2.129218216 cm
Rounded to 2 decimal places:
WZ=2.13 cm

Answer: The <span>measurement is closest to the measure of segment WZ is
2.13 cm</span>

The sum of two numbers is 21. The larger number is 6 less than twice the smaller number. Find the two numbers.
Vesnalui [34]
Hey there! :D

21= 2x-6+x

21=3x-6

27=3x

x=9

The smaller number is 9. 

The larger number is:

9*2= 18 18-6= 12

The larger number is 12. 

I hope this helps!
