Answer:

B

Step-by-step explanation:

We have the expression:

(3-5i)(-2+4i)

Distributive Property:

=(3-5i)(-2)+(3-5i)(4i)

Distribute:

=(-6+10i)+(12i-20i^2)

Simplify:

=(-6+10i)+(12i-20(-1))

Simplify:

=-6+10i+12i+20

Combine like terms:

=(-6+20)+(10i+12i)

Simplify:

=14+22i

Hence, our answer is B.

Can u help this helpless 9th grader ?
nexus9112 [7]

Answer:

y = 4x + 32

Step-by-step explanation:

Given: Temperature at sunrise = 32°F

y is the temperature after x hours of sunrise

Temperature change is 4°F/hour.

The equation of a line in slope intercept form is given by

y = mx +c

where m is the slope, which is the change in value of y to the value of x

and c is the value of y at x = 0

At sunrise, x =0 and y =32

∴ c = 32

Also we see that the change in temperature to that of time is 4/1 = 4

∴ m = 4

Substituting the values of m and c in the equation of line, we have

y = 4x +32

What is the approximate circumference of a circle with a diameter of 300 feet
almond37 [142]
Circumference = 2πr

Since you know the diameter is 300, you divide it by 2 to find the radius. Therefore, the radius is 150.
Now plug it into the formula: C = 2(3.14)(150)
                                              C = 942

Answer: Circumference is 942 feet
