EleoNora [17]
From 2010 year to 2015 year 5 years passed, then t is equal to 5.
To find how many people attended the festival in 2015 we have to calculate y(5): 
y(5)=180,000(1.2)^{5}=180,000*2.48832=447,898

Y+5=2(x+1)<br><br><br> what is the slope for this Math
Stells [14]

Answer:

2

Step-by-step explanation:

The slope-intercept form is

y=mx+b, where m is the slope and b is the y-intercept.y=mx+bRewrite in slope-intercept form.Simplify 2(x+1).Apply the distributive property.

y+5=2x+2⋅1

multiply 2 by 1.

y+5=2x+2

y+5=2x+2

Move all terms not containing y to the right side of the equation.Subtract 5 from both sides of the equation.

y=2x+2−5

y=2x−3

the slope is the "m" so the slope is 2

Given w1 = -2 + 3i and W2 = 4 - 4i, which complex number can be added to Wi to produce wz?
lyudmila [28]

Given:

Two complex numbers are w_1=-2+3i and w_2=4-4i.

To find:

The complex number that can be added to w_1 to produce w_2.

Solution:

Let complex number z= is added to w_1 to produce w_2.

w_1+z=w_2

z=w_2-w_1

On substituting the values, we get

z=(4-4i)-(-2+3i)

z=4-4i+2-3i

Combine like real and imaginary parts.

z=(4+2)+(-4-3)i

z=6+(-7)i

z=6-7i

Therefore, the correct option is C.
