Answer:
(4 + 5i)(2 - 7i) = 8 - 28i + 10i + 35
= 43 - 18i
4 + 5i(2 - 7i) = 4 + 10i + 35
= 39 + 10i
A small business has 15 full-time employees. How many people does the small business employ if the full-time workers make up 30% of the employees the company has?
Answer:
50 employees
Step-by-step explanation:
The total number of employees the business has will have to be made up the full-time employees and part-time employees.
The number of full-time employees = 15
Let the total number of employees = x
[tex]15 = 30 percent of x[/tex]
[tex]15 = 30/100 \times x\\x=1500/30 = 50[/tex]
The company has a total of 50 employees

What is the slope of a line perpendicular to the line whose equation is
10x – 8y = -80. Fully reduce your answer.
Answer:
-4/5
Step-by-step explanation:
write the given equation in y=mx+b form, where m is the slope
10x-8y=-80
-8y= -10x-80 divide both sides by -8
y=(10/8)x+10
y=(5/4)x+10
m= 5/4 is the slope of the given function
the slope of an equation that is perpendicular is the negative reciprocal of the given one so is
m= -4/5
Which transformation maps B (2,5) to B'(-2,-5)?
A. A 90 degree rotation

Answer:
it will be C) SAS(side angle side)
b) Amount
Rs 5760, Interest
Rs 1526
Given :
Amount, A = 5760 Rs.
Interest in the amount, I = 1526 Rs.
To Find :
We need to find the % rate of interest.
Solution :
Let, us assume it is simple interest.
So,
[tex]Interest = \dfrac{price \times rate \times time}{100}\\\\1526 = \dfrac{5760 \times r \times m}{100}\\\\r = \dfrac{152600}{5760m}\\\\r = \dfrac{26.5}{m}[/tex]
Hence, this is the required solution.

we can use crisscross multipleWhat is the answer?
Answer:
clockwise
Q= (5,-2)
R= (-1,-3)
S= (0,0)
T= (3,-2)
counterclockwise
Q= (-5,2)
R= (1,3)
S= (0,0)
T= (-3,-2)
Step-by-step explanation:
this might not be right im a little rusty on my transformations but here goes nothing.
i dont know if this is a clockwise or a counter clockwise rotation so ill do both options.
clockwise (x,y) - (y,-x)
q=(2,5) - (5,-2)
r=(3,-1) - (-1,-3)
s=(0,0) - (0,0)
t=(-2,3) - (3,2)
counterclockwise (x,y) - (-y,x)
q=(2,5) - (-5,2)
r=(3,-1) - (1,3)
s=(0,0) - (0,0)
t=(-2,3) - (-3,-2)

Step-by-step explanation
given f (x) = 5x + 1, find f (-3)
Answer:
f(- 3) = - 14
Step-by-step explanation:
To evaluate f(- 3), substitute x = - 3 into f(x), that is
f(- 3) = 5(- 3) + 1 = - 15 + 1 = - 14
