What Is The Product Of Z And W? -20 + 101-15 + 518-4120 10i

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Answer 2

The product of z and w is (-20+10i).

What are imaginary numbers?

An imaginary number is a real number multiplied by the imaginary unit i.

Given is a coordinate plane showing imaginary and real numbers.

Coordinates of w = (-5, 5i)

Coordinates of z = (3,i)

w*z = (-5, 5i)* (3,i)

= -15-5i+15i-5

= -20+10i

Hence, The product of z and w is (-20+10i).

Point-slope form of the line that passes through (-8,2) and is perpendicular to a line with a slope of -8

Answers

Answer:

y-2=1/8(x+5)

Step-by-step explanation:

1. Perpendicular lines have opposite slopes. To get the new slope, take the slope of the first line and turn it to make it the opposite reciprocal.

Since it's -8, the opposite of it is 1/8.

2. Now, use point slope: y-y1=m(x-x1). Plug in the values of the ordered pair and the slope into the equation.

y-2=1/8(x+8)

And that's your answer

Connor is correct because the water is flowing in at a rate which is about 2 gallons per minute.

Connor is not correct because the water is flowing in at a rate which is faster than 2 gallons per minute.

Connor is not correct because the water is flowing in at a rate which is slower than 2 gallons per minute.

Connor is correct because the rate of water flowing is less than the slope.

Find the formula for an exponential function that passes through the two points given. (x, y) = (0, 4) and (x, y) = (3, 32)

Answers

Given:

The exponential function passes through two points (0,4) and (3,32).

To find:

The formula for the exponential function.

Solution:

The general form of an exponential function is

[tex]y=ab^x[/tex]          ...(i)

where, a is initial value and b is growth factor.

The exponential function passes through two points (0,4) and (3,32). It means the function must be satisfy by these points.

Putting x=0 and y=4 in (i), we get

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

Putting a=4, x=3 and y=32 in (ii), we get

[tex]32=4b^3[/tex]

Divide both sides by 4.

[tex]8=b^3[/tex]

Taking cube root on both sides.

[tex]2=b[/tex]

Putting a=4 and b=2 in (i), we get

[tex]y=4(2)^x[/tex]

Therefore, the required formula for the exponential function is [tex]y=4(2)^x[/tex].

Answers

Answer:

yes

Step-by-step explanation:

it is going by 5s.

Answer:

Yes. This is because if you plot the numbers on a ration table or see the graph points, you can see a pattern: you multiply by 5. The equation to solve this would be y=5x. Another reason why this is proportional is that the graph starts from the origin (0,0) This is the opposite for non-proportional relationships. Hope this helps! :)
