What is the product of the complex numbers (-3i+4) and (3i+4)?
Answer: 25
Step-by-step explanation:
Finding the product of complex numbers is not different to finding the product of real numbers
(-3i+4) * (3i+4) = -9i^2 + 12i - 12i + 16 = 25
Answer:
25
Step-by-step explanation:
An easy way to multiply binomials is the FOIL(first, outer, inner, last) method. Multiply the first terms of each binomial, -3i×3i=-9i^2. Then do the outer terms, -3i×4=-12i. Then do the inner terms 4×3i=12i. Then do the last terms, 4×4=16. Lastly combine like terms, the -12i and 12 cancel out, and you're left with -9i^2+16. i^2=1, so then you get -9(-1)+16. -9×-1=9. 9+16=25
Find the area of each shaded region
[tex]\bold{\huge{\blue{\underline{ Solution }}}}[/tex]
Given :-The radius of the circle is 5 unitsTo Find :-We have to find the area of shaded region .Let's Begin :-The given figure is composed of two figures triangle and circle. In which triangle is enclosed in the circle.
The triangle is the unshaded region of the given figureWe know that,
Area of triangle
[tex]\bold{\red{ = }}{\bold{\red{\dfrac{1}{2}}}}{\bold{\red{\times{ Base }}}}{\bold{\red{\times{ height }}}}[/tex]
Here,
The base of the triangle is equal to the diameter of the circle that is, [tex]\sf{ Base = 5 + 5 = 10 \: units }[/tex]The height of the triangle is equal to the radius of the triangle that is[tex]\sf{ Height = 5 \:units }[/tex]Subsitute the required values,
Area of the given triangle
[tex]\sf{ = }{\sf{\dfrac{1}{2}}}{\sf{\times{ 10 }}}{\sf{\times{ 5 }}}[/tex]
[tex]\sf{ = 5 }{\sf{\times{ 5}}}[/tex]
[tex]\bold{ = 25\: units }[/tex]
Thus, The area of triangle is 25 units
NowWe have to find the area of the circle
The radius of the circle is 5 unitsWe know that,
Area of circle
[tex]\bold{\pink{ = }}{\bold{\pink{\pi{r^{2}}}}}[/tex]
Subsitute the required values,
[tex]\sf{ = }{\sf{\pi{(5)^{2}}}}[/tex]
[tex]\sf{ = }{\sf{\dfrac{22}{7}}}{\sf{\times{ 25}}}[/tex]
[tex]\sf{ = }{\sf{\dfrac{550}{7}}}[/tex]
[tex]\bold{ = 78.57\: units }[/tex]
Thus, The area of circle is 78.57 units
Therefore,Area of shaded region
= Area of circle - Area of triangle
Subsitute the required values,
[tex]\sf{ = 78.57 - 25 }[/tex]
[tex]\bold{\green { = 53.57 \: units }}[/tex]
Hence, The area of shaded region is 53.57 units.
The area of the shaded figure is 13.375 square units.
What is the area of the shaded region?
The shaded region is a circle with a triangle inside of it removed.
To get the area, we need to get the area of the circle and remove the area of the triangle.
Remember that for a circle of radius R, the area:
A = 3.14*R^2
In this case, we can see that the diameter of the circle measures 5 units, then the radius (half of the diameter) measures 2.5 units.
A = 3.14*(2.5)^2 = 19.625 square units.
And a triangle of base B and height H has an area:
A' = B*H/2
In this case, the base of the triangle is equal to the diameter of the circle, and the height is equal to the radius of the circle, so we have:
B = 5 units.
H = 2.5 units.
Then:
A' =5*2.5/2 = 6.25 square units.
Then the shaded area is:
shaded area = 19.625 square units - 6.25 square units.
= 13.375 square units.

A ship has an island directly in the path of the destination port, so it has to travel 11.5 miles west and then 8.4 miles north to get to the port. To the nearest tenth,how much shorter would the trip be if the ship could go directly to port?
Answer:
Step-by-step explanation:
The direct distance there (without the island in the way) is found using the Pythagorean Theorem
c^2 = a^2 + b^2
a = 8.4
b = 11.5
c = ?
c^2 = 8.4^2 + 11.5^2 Square the length of the legs.
c^2 = 70.56 + 132.25 Combine
c^2 = 202.81 Take the square root.
c = 14.24
But the island is there. The distance travelled = 8.4 + 11.5 = 19.9 miles
So the additional distance = 19.9 - 14.24 = 5.66 miles.

One equation in a system of equations is given in the graph. Which equation below would have to be the second equation so that the system has no solutions?
Solution:
To classify the system of equations as no solutions, the lines must be parallel (Not intersect).
First, let's identify the equation forming the line.
Slope = Rise/Run = 2/-3 = -0.66Y-intercept = 0Equation formed: y = -2/3We also know that the slope of the equation must be -1.5.
A) 2x + 3y = 0
3y = 0 - 2x=> 3y = -2x=> (y = -2x/3) ∦ (y = -2x/3)B) 2x + 3y = 6
=> 3y = -2x + 6=> (y = -2x/3 + 2) ║ (y = -2x/3)C) 2x - 3y = 9
=> -3y = -2x + 9=> y = -2x/-3 + 9/-3=> (y = 2x/3 - 3) ∦ (y = -2x/3)D) y = 3x + 2
(y = 3x + 2) ∦ (y = -2x/3)Option B is correct.
The ratio of boys to girls is 4:5 calculate the number of boys if there are 1080 learners
Answer:
480 Boy
Step-by-step explanation:
The ratio of Boys = 4x
The ratio of Girls = 5x
The Number of Boys in the School = 4x + 5x = 1080
= 9x = 1080
= x = 1080/9
= x = 120
The ratio of Boys = 4x = 4 x 120 = 480
The ratio of Girls = 5x = 5 x 120 = 600
Hence, Number of Boys = 480
Ratio Boys to Girls = 480:600

x - 18 = 20 one step equations
Answer: the answer is x=38
Step-by-step explanation:
X-18=20 we see that 18 is being SUBTRACTED from the x which means we have to do the opposite of subtraction is addition so 20+18=38
To check: you can plug 38 for x and subtract it from 18
Demonstration: 38-18=20
X = 38
Step-by-step explanation:
X-18 = 20
we move the constants (numbers) to one side and keep the variable, unknown on the other side
X= 20+18 (we change the sign whenever we move something to the opposite side)
x= 38
Based on data from 2011-2012, the percentage of 6- to 11-year-olds who were obese was about _____ than the percentage of two- to five-year-olds who were obese.
Using the percentage concept, it is found that the percentage of 6- to 11-year-olds who were obese was about 17.76% more than the percentage of two- to five-year-olds who were obese.
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
Researching on the internet, we find that:
The percentage of two-to-five year old who are obese is of a = 15.2%.The percentage of 6-to-11 year old who are obese is of b = 17.9%.Hence:
[tex]P = \frac{17.9}{15.2} \times 100\% = 117.76\%[/tex]
117.76% - 100% = 17.76%.
Hence the percentage of 6- to 11-year-olds who were obese was about 17.76% more than the percentage of two- to five-year-olds who were obese.

Find the mean, median, and mode of 45, 52, 17, 63, 57, 42, 54, 58
Answer:
Step-by-step explanation:
to find the mean is another way of saying to find the average. To do this we add all the listed values(45,52,17,63,57,42,54,58) then divide them by how many values we are given which in this case is 7. so the mean would be 49. now to find the median we must first put the values in numeric order(17,42,45,52,54,57,58,63) then see the number in the middle or in cases or even number of values we find the two values in the middle of the set then we add them together and divide by two. which would be 53. now to find the mode we simply find the most reoccurring number in the set and seeing as there are no repeated values in this set there is no mode.
Will give brainliest!!! Plz help
Answer:
115.5
Step-by-step explanation:
comparing side lengths of 49 and 28:
49 ÷ 28 = 1.75, so to get from 28 to 49 multiply by 1.75
this is the same thing for side lengths 38.5 and 22 as
22 × 1.75 = 38.5
the scale factor of the first triangle (GHI) to the second triangle (JKL) is 1.75 which means multiply each side of the first triangle by 1.75
so to work out x:
16 × 1.75 = 28
perimeter of JKL (second triangle) - add up lengths of the sides:
28 + 38.5 + 49 = 115.5

8. The battery power is inversely proportional to time for which it used.
9. The ability of do work hard is inversely proportional to age of man after youngness to onward.
10. The number of mistake in work is inversely proportional to practice.
Explanation:
Direct Variation: A relationship where one quantity is a constant multiplied by another quantity is called direct variation.
Inverse Variation: Inverse variation is defiend as the relationship between two variables in which the resultant product is a constant. If a is inversely proportional to b, the form of equation is a = k/b, where k is constant. Inverse variation is known as the opposite of direct variation. If there an increas ein one variable, the other variable decreases in proportion so that the resultant product remains unchanged.
