Answer:

-3 is y intercept

Explanation:

  • formula: y = mx + b

                                 where m is the slope and b is the y-intercept

comparing with the formula. we can say that -5 is the slope and -3 is the y intercept.

Evan runs a website that has gotten quite popular. However, its popularity seems to be decreasing and the site is now getting 7%
anyanavicka [17]

Answer:

(a-b) *(a-b) *(a-b)

=(a*a*a) -3*(a*a*b)+3*(a*b*b)-(b*b*b)

34000*(1-7%)*(1-7%)*(1-7%)

=34000*(1-0.07)*(1-0.07)*(1-0.07)

=34000*[(1*1*1)-3*(1*1*0.07)+3*(1*0.07*0.07)-(0.07*0.07*0.07)]

=34000*(1-0.21+0.0147-0.000343)

=34000*(0.804357)

=34*1000*(804.357/1000)

=34*804.357

=<u>27348.138</u>

<u>=</u><u>27348</u>

A cone with radius 2 and height 9 has its radius tripled. How many times greater is the volume of the larger cone than the small
SpyIntel [72]

Answer:

When increasing the radius 3 times the volume increases 9 times and when it is reduced to a third the volume decreases 9 times

Step-by-step explanation:

We have that the formula for the volume of a cone is:

Vc = pi * (r ^ 2) * h

We first calculate the original volume, where the radius is 2 and the height is 9, replacing:

Vc = 3.14 * (2 ^ 2) * 9

Vc = 113.04

Now if the radius is tripled it would be: 2 * 3 = 6, the radius would be 6, replacing:

Vc = 3.14 * (6 ^ 2) * 9

Vc = 1017.36

If we compare:

1017.36 / 113.04 = 9

This means that when the radius is tripled, the volume increases 9 times.

When if re reduces to a third the radius would be: 2/3, replacing:

Vc = 3.14 * ((2/3) ^ 2) * 9

Vc = 12.56

113.04 / 12.56 = 9

Which means that by reducing it to a third the volume becomes 9 times smaller.

The base of an isosceles triangle is one and a half times the length of the other two sides. A smaller triangle has a perimeter
stira [4]

Answer:

P = 1.5x.

Step-by-step explanation:

Let the length of each side of the first triangle be x, then

Perimeter of this triangle

= 2x + 1.5x

= 3.5x.

So perimeter of smaller triangle is:

P = 1/2 * 3.5x

P = 1,.5x.
