Answer: Point C.
Step-by-step explanation:
Point B represents the quotient of 4+3i/-i.
What is a complex number?Complex numbers are the numbers that are expressed in the form of
a + ib where, a, b are real numbers and 'i' is an imaginary number called “iota”.
Given complex number
[tex]\frac{4+3i}{-i}[/tex]
= [tex]\frac{4+3i}{-i} \times \frac{i}{i}[/tex]
= [tex]\frac{4i+3i^{2} }{-i^{2} }[/tex]
= [tex]\frac{4i+3(-1) }{-(-1)}[/tex]
= [tex]4i-3[/tex]
= [tex]-3+4i[/tex]
Point B represents the quotient of 4+3i/-i.

Find the area of triangleABC to the nearest tenth.
Answers
Answer:
62.3 units²
Step-by-step explanation:
We would apply the formula for area of a triangle given an included angle, which is A = ½*ab*sin C
Where,
a = 11
b = 14
C = 54°
Substitute
Area = ½*11*14*sin 54
Area = 62.2943085 ≈ 62.3 units² (nearest tenth)

which expression can he used to find the surface area of the following sqare pyramid
Answers
Answer:
answer: A
Because when doing area for triangles its
base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16
so it would come out to 16 + 10 + 10 + 10 + 10 =

This would equal 123/8.
Now, we aren’t done yet. To get our final answer, we would to simplify 123/8 to the point where it can’t be any more simple. (For example, if we had 2/2, we would have to simplify that because 2/2 = 1. We wouldn’t be able to simplify the 1 any more than that, making 1 the final answer.) I’ll just do the math for you here. 123/8 simplified completely is 15 3/8.
( 123/8 = 15 3/8.)

Mrs. Roberts sewed m shirts using 2 yards of cloth for each shirt. She also sewed (m+2) dresses, using 5 yards of cloth for each dress. A) How much cloth did she use altogether? Give your answer in terms of m. B) If m= 7, find how much more cloth she used to sew the dresses than the shirts.
Answers
Answer:
7m + 10
31 yards
Step-by-step explanation:
Shirts :
Number of shirts sewed = m
Yards of cloth used per shirt = 2 yards
Number of dresses sewed = m + 2
Yards of cloth used per dress = 5 yards
Cloth used altogether :
Cloths used for shirt = 2 * m = 2m
Cloth used for dress = 5 * (m+2) = 5m + 10
2m + (5m + 10) = 7m + 10
If m = 7
Cloth used for dress - Cloth used for shirt
(5(7) + 10) - (2(7))
(35+10) - 14
45 - 14 = 31 yards

If you know that cosine of the obtuse supplementary angle -0.3456 what can you determine about the acute angle
Answers
Answer:
69.8°
Step-by-step explanation:
Since cosФ = -0.3456
Ф = cos⁻¹(-0.3456)
Ф = 110.2°
Since the angles are supplementary, let the acute angle be x
So, x + 110.2° = 180°
x = 180° - 110.2°
x = 69.8°

Step-by-step explanation:
Let us use sine law to find the length of the yellow cable. Note that a cable of length 64 m is directly opposite the 112° angle and the 58° angle is directly opposite the unknown cable length. We can the set up our sine law as follows:
[tex] \frac{x}{ \sin(58) } = \frac{64 \: m}{ \sin(112) } [/tex]

Malik got a 200 cafe gift on January 1. He always orders decaf mochas which cost 5 each. At the end of January, maliks gift card has 125 left. Write an equation with x as your variable.
Answers
Answer:
200 - 5x = 125
Step-by-step explanation:
Let the number of orders made by Malik in the month of January = x
Each order costs = $5
Total cost of decaf mochas in one order = $5x
Malik had cake gift on 1st of January = $200
Amount of money left with Malik at the end of January = $125
Therefore, equation representing this situation will be,
200 - 5x = 125

What is the area of circle circumscribing a triangle?
An imaginary tangent line stretching from the triangle's two sides plus a section of the curve that is tangent to one side create this combination. The formula for the radius of a circle enclosing a triangle is
r = ABC / 4A.
Solution:
area of sector ABC = 85/360 × π × (7.3)² cm²
= 39.53 cm²
area of triangle ABC = 1/2 × 9 × 5.7 cm²
= 25.65 cm²
area of shaded region = area of sectot ABC ₋ area of triangle ABC
= 39.53 ₋ 25.65
= 13.88 cm²
Hence the area of shaded region is 13.88 cm²
