Answer:
1. In the multiplication of the imaginary parts, the student forgot to square of i. OR
2. The student has only multiplied the real parts and the imaginary parts.
Correct value
.
Step-by-step explanation:
The given expression is

A student multiplies (4+5i) (3-2i) incorrectly and obtains 12-10i.
Student's mistake can be either 1 or second:
1. In the multiplication of the imaginary parts, the student forgot to square of i.
2. The student has only multiplied the real parts and the imaginary parts.

Which is not correct. The correct steps are shown below.
Using distributive property, we get



![[\because i^2=-1]](https://tex.z-dn.net/?f=%5B%5Cbecause%20i%5E2%3D-1%5D)


Therefore, the correct value of
is
.
Answer:
- Architect
- Cartographer and Photogrammetrist
- Drafter
- Mechanical Engineer
- Surveyor
- Urban and Regional Planner
Step-by-step explanation:
Architects utilize geometric principles while designing layouts for their ongoing projects, which can include buildings, electrical systems, and plumbing architecture.
Cartographers utilize geographic data to create or update maps for use in education, as well as environmental presentations.
Using the same geometric knowledge and applications as architects and engineers, drafters create design plans with the use of computer-aided design (CAD) software.
Mechanical engineers, some of the most diversified engineers, use a multitude of geometric concepts to design mechanical devices, or update existing structures.
Surveyors use geometry to take exact measurements of boundaries for different types of property.
Urban and regional planners rely on the same geometry practices used by surveyors when examining the positives and negatives of introducing new and updated plans for a community.

Answer:
610
Step-by-step explanation:
Given:
- 259 emails on Monday
- 431 emails on Tuesday
- ? emails on Wednesday
- Total emails = 1300
Add:
259 + 431 = 690
Subtract:
1300 - 690 = 610
So, on Wednesday 610 emails were sent out.
Hope this helped.
