might be wrong but i think A
Step-by-step explanation:
Answer:
the modulus of a complex number z = a + bi is:
Izl= √(a²+b²)
The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:
m = 2 + 6i
n = a + bi
Im + nl = 3√10
√(a² + b²+ 2²+ 6²)= 3√10
√(a^2 + b^2 + 40) = 3√10
squaring both side
a²+b²+40 = 3^2*10 = 9*10 =90
a²+b²= 90 - 40
a²+b²=50
So,
|n|=√(a^2 + b^2) = √50
The modulus of n must be equal to the square root of 50.
now
values a and b such
a^2 + b^2 = 50.
for example, a = 5 and b = 5
5²+5²=25+25= 50
Then a possible value for n is:
n = 5+5i

Answer:
A) sin θ = 3/5
B) tan θ = 3/4
C) csc θ = 5/3
D) sec θ = 5/4
E) cot θ = 4/3
Step-by-step explanation:
We are told that cos θ = 4/5
That θ is the acute angle of a right angle triangle.
To find the remaining trigonometric functions for angle θ, we need to find the 3rd side of the triangle.
Now, the identity cos θ means adjacent/hypotenuse.
Thus, adjacent side = 4
Hypotenuse = 5
Using pythagoras theorem, we can find the third side which is called opposite;
Opposite = √(5² - 4²)
Opposite = √(25 - 16)
Opposite = √9
Opposite = 3
A) sin θ
Trigonometric ratio for sin θ is opposite/hypotenuse. Thus;
sin θ = 3/5
B) tan θ
Trigonometric ratio for tan θ is opposite/adjacent. Thus;
tan θ = 3/4
C) csc θ
Trigonometric ratio for csc θ is 1/sin θ. Thus;
csc θ = 1/(3/5)
csc θ = 5/3
D) sec θ
Trigonometric ratio for sec θ is 1/cos θ. Thus;
sec θ = 1/(4/5)
sec θ = 5/4
E) cot θ
Trigonometric ratio for cot θ is 1/tan θ. Thus;
cot θ = 1/(3/4)
cot θ = 4/3

Andre can run 2 1/2 miles in 3/4 hour. Find his average speed in miles per hour
Answer:
3 1/3 miles per hour
Step-by-step explanation:
's' = average speed
(5/2 ÷ 3/4) = (s ÷1)
(5/2 ÷ 3/4) = 10/3
10/3 = s/1
cross-multiply:
3s = 10
s = 10/3
s = 3 1/3 miles per hour
can someone please help me
Answer:
B
Step-by-step explanation:
its a right angle and one point is 40 as shown already so 90-40=50 hope this helps
So you would take your 90° angle which is the box on the bottom right hand corner and add 40° which would equal 130° and then you would subtract 180° -130° and you would get 50°.

Answer:
Cost of car including VAT = $17,700
Step-by-step explanation:
Given:
Cost of car without VAT = $15,000
Rate of VAT = 18%
Find:
Cost of car including VAT
Computation:
Cost of VAT = Cost of car without VAT x Rate of VAT
Cost of VAT = 15,000 x 18%
Cost of VAT = 15,000 x 18
Cost of VAT = $2,700
Cost of car including VAT = Cost of car without VAT + Cost of VAT
Cost of car including VAT = 15.000 + 2700
Cost of car including VAT = $17,700
Solve for X ...........
Answer:
x = 46
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
2(2 + x) = 6(6 + 10)
2(2 + x) = 6 × 16 = 96 ( divide both sides by 2 )
2 + x = 48 ( subtract 2 from both sides )
x = 46

Answer:
[tex]140[/tex]
Step-by-step explanation:
A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:
[tex]3a+b+3=2a+2b+6[/tex]
Solving, we will get a in terms of b:
[tex]3a=2a+b+3,\\a=b+3[/tex]
Now we can substitute a for (b+3) into our equation:
[tex]5a-2b+1=2a+2b+6,\\5(b+3)-2b+1=2(b+3)+2b+6,\\3b+16=4b+12,\\-b=-4,\\b=\boxed{4}[/tex]
Therefore, the length of each side of this polygon is [tex]5(4+3)-2(4)+1=28[/tex].
Since the perimeter of the polygon consists of all five sides, the perimeter is:
[tex]p=28\cdot 5 =\boxed{140}[/tex]

5f = -75 check your solutio\
Answer:
f= -15
Step-by-step explanation:
u just have to divide
-75/5= -15 so f equal -15
Answer:
F=-15
Step-by-step explanation:
You want to get f by it’s self so to do that you would have to divide. So you would divide 5 by -75 to get -15 ( it’s a negative because a negative number divided by a positive number is a negative number). To check your math you would take 5 and multiply by -15 and that equals -75 (a negative number times a positive number is a negative number)

Answer:
- Mode-The most repetitive number.
- Median:The number in the MIDDLE when they are IN ORDER.
- Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS.
- Range - THE BIGGEST minus the Smallest.
Step-by-step explanation:
;)
Answer:
mean: average of all the numbers, so add all numbers, divide by the amount of numbers you added
median: sort all the numbers from least to greatest, then the middle is the answer, if there are 2 in the middle, both are the answer
mode: the number that appeared most
range: the largest number minus the smallest number

Helen has 2 winter coats, 4 hats and 3 scarves. How many different outfit combinations does Helen have to chose from?
Given:
Number of winter coats = 2
Number of hats = 4
Number of scarves = 3
To find:
The total number of different outfit combinations.
Solution:
Number of winter coats is 2. So, the number of ways to select a winter coat from 2 coats is 2.
Number of hats is 4. So, the number of ways to select a hat from 4 hats is 4.
Number of scarves is 3. So, the number of ways to select a scarf from 3 scarves is 3.
So, the total number of ways is:
[tex]2\times 4\times 3=24[/tex]
Therefore, Helen have 24 different outfit combinations.
