Given:
4 - 3iConjugate of the given number is:
4 + 3iDivide the given number by its conjugate:
(4 - 3i) / (4 + 3i) = (4 - 3i)(4 - 3i) / (4 + 3i)(4 - 3i) =(16 + 9i² - 24i) / (16 - 9i²) = (16 - 9 - 24i) / (16 + 9) = (7 - 24i) / 25 = 7/25 - 24i/25Correct choice is B

A tunnel is built in form of a parabola. The width at the base of tunnel is 7 m. On
the ceiling 3 m from each end of the base there are light fixtures. The height to light
fixtures is 4 m. A trailer truck carrying cars is 4 m wide and 2.8 m high is going to drive
through the tunnel? Is this possible? (Give full algebraic solution.
Given:
The width at the base of parabolic tunnel is 7 m.
The ceiling 3 m from each end of the base there are light fixtures.
The height to light fixtures is 4 m.
To find:
Whether it is possible a trailer truck carrying cars is 4 m wide and 2.8 m high is going to drive through the tunnel.
Solution:
The width at the base of tunnel is 7 m.
Let the graph of the parabola intersect the x-axis at x=0 and x=7. It means x and (x-7) are the factors of the height function.
The function of height is:
[tex]h(x)=ax(x-7)[/tex] ...(i)
Where, a is a constant.
The ceiling 3 m from each end of the base there are light fixtures and the height to light fixtures is 4 m. It means the graph of height function passes through the point (3,4).
Putting x=3 and h(x)=4 in (i), we get
[tex]4=a(3)((3)-7)[/tex]
[tex]4=a(3)(-4)[/tex]
[tex]\dfrac{4}{(3)(-4)}=a[/tex]
[tex]-\dfrac{1}{3}=a[/tex]
Putting [tex]a=-\dfrac{1}{3}[/tex], we get
[tex]h(x)=-\dfrac{1}{3}x(x-7)[/tex] ...(ii)
The center of the parabola is the midpoint of 0 and 7, i.e., 3.
The width of the truck is 4 m. If is passes through the center then the truck must m 2 m on the left side of the center and 2 m on the right side of the center.
2 m on the left side of the center is x=1.5.
A trailer truck carrying cars is 4 m wide and 2.8 m high is going to drive through the tunnel is possible if h(1.5) is greater than 2.8.
Putting x=1.5 in (ii), we get
[tex]h(1.5)=-\dfrac{1}{3}(1.5)(1.5-7)[/tex]
[tex]h(1.5)=-(0.5)(-5.5)[/tex]
[tex]h(1.5)=2.75[/tex]
Since h(1.5)<2.8, therefore the trailer truck carrying cars is 4 m wide and 2.8 m high is going to drive through the tunnel is not possible.
Closest to the shaded area
Answer:
B) 30.9
Step-by-step explanation:
So, because the radius is 6, we know the diameter is 12, meaning we know each side is 12, so the total area of the square is 144.
To find the area of a square we should use pi(r) ^2 which is pi(6) ^2 which is 113.09. to find the area of the shaded are we would subtract these. 144- 113.09 this gets us 30.91, this is closest to B) 30.9
Ferris wheel diameter was 250 feet. Calculate it’s radius. If 40 steel rods were joined at the centre find the total steel required?
Answer:
785.5ft
Step-by-step explanation:
Given data
Diameter= 250ft
Radius= D/2= 250/2= 125ft
The total steel required can be found from the Circumference
C= 2πr
C= 2*3.142*125
C= 785.5ft
Hence the total steel required is 785.5ft

The formula for the area of a triangle is 1A bh2=, where b is the length of the base and his the height. Rearrange the formula to isolate h
Answer:
h = 2A/b
Step-by-step explanation:
Area of a triangle, A = 1/2bh
Where,
b = base of the triangle
h = height of the triangle
Rearrange the formula to isolate h
A = 1/2bh
Multiply both sides by 2
2 * A = 2 * 1/2bh
2A = bh
Divide both sides by b
2A / b = bh / b
2A / b = h
Therefore,
h = 2A/b

Answer:
area = 32
perimeter = 30
Step-by-step explanation:
Formulas:
Area of a parallelogram: A = bh
Perimeter of a parallelogram: P = 2 ( b + s )
Where h = height s = slant height and b = base length
Define:
b = 8
h = 4
s = 7
Plug in given values into formulas and calculate
A = (8)(4)
8 * 4 = 32
A = 32
P = 2 ( 8 + 7 )
8 + 7 = 15
2(15) = 30
P = 30

What is the area of this figure? 5 in 6 in 15 in 16 in 10 in 20 in
Answer:
230 in.²
Step-by-step explanation:
20 · 10 = 200 in.²
5 · 6 = 30 in.²
200 in.² + 30 in.²
Answer:
230 sq in
Step-by-step explanation:
You can find entire area (20 x 16) and subtract out the area of the missing piece (15 x 6)
20 x 16 = 320
15 x 6 = 90
320 - 90 = 230

Answer:
[tex]47x^3\sqrt{5x}[/tex]
Step-by-step explanation:
The objective is to combine the terms to make one radical, so therefore we know that we will have to take a [tex]\sqrt{5}[/tex] out of the second radical [tex]\sqrt{180}[/tex].
If we divide 180 by 5, we will get 36, so now we have
[tex]\sqrt{180}=\sqrt{5}[/tex]×[tex]\sqrt{36}[/tex]
[tex]\sqrt{36}[/tex] can be simplied into just 6.
So now the expression becomes
[tex]-\sqrt{5x^7}+8x^2*6 \sqrt{5x^3}[/tex]
Then we can further simplify by moving the [tex]x^{2}[/tex] into the radical to get two common terms with [tex]\sqrt{5x^7}[/tex].
[tex]x^{2} =\sqrt{x^4}[/tex], so we now have
[tex]-\sqrt{5x^7}+ 8\sqrt{x^4} *6 \sqrt{5x^3}[/tex]
So then we can combine the two radicals to get the expression to
[tex]-\sqrt{5x^7}+48\sqrt{5x^7}[/tex]
We now see that we have two terms with a common radical, and coefficients of -1, and 48.
That allows us to simplify further to
[tex]47\sqrt{5x^7}[/tex]
Here, we can take out [tex]\sqrt{x^6}[/tex], which is [tex]x^3[/tex], and get the final simplied form to be
[tex]47x^3\sqrt{5x}[/tex]

Let’s figure out one more adjustment for the butterscotch chip cookies. The butterscotch chip cookie recipe calls for 12 ounces of chips for every 2 cups of flour. How many ounces of chips are needed if 3 cups of flour are added?
Remember to keep your units consistent.
I believe it would 18 ounces of chips for 3 cups of flour. If you take half of 12 ounces then you get 6 ounces per cup of flour. Adding 6 ounces to the 12 would get us the total of the 18 ounces.

The circumference of a circle is 100.48 feet. What is the circle's diameter?
Answer:
631.334460 ft
Step-by-step explanation:
i think
Answer:
32 feet
Step-by-step explanation:
Since we know that the formula for finding circumference is C = π · d, and π is equal to 3.14, we reverse the formula so it fits what information we have.
We know that C = 100.48 and we also know that π = 3.14 so all we have to find is the diameter.
To do this, you divide 100.48 by 3.14 to get 32 feet as your final answer.
