[tex](2 + \sqrt{3}) - (1 + \sqrt{3})i[/tex]
Answer:
(b) (2+√3) -(1+√3)i
Step-by-step explanation:
Add like terms. Real terms are added; imaginary terms are added.
(√3 -i) + (2-√3i) = (√3 +2) +(-i -√3i)
= (√3 +2) -i(1 +√3) . . . . . the common factor of -i can be factored out

what is .072 divided by 345.00 rounded to the nearest tenth?
Answer:
.072 / 345.00 = 0.0002086956
the tenth place is the first digit to the right of the decimal point so it would round to 0.0
Round to the nearest tenth of the number is 0.
We need to round it to the nearest tenth.
Write the above expression in fractional form.
{0.072}{345} = 0.00028
the Round to the nearest tenth of the number is 0.

Can someone help me with this please?
Step-by-step explanation:
we have one large rectangle and 2 small right-angled triangles to add.
the area of the rectangle is easy : 15×25 = 375
the right-angled triangle on the long side has one side = 5, and the "invisible" side is 25 - 12 - 5 = 8.
these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.
the area of a triangle is baseline×height/2.
so, the area of the this triangle is 8×5/2 = 20.
the right-angled triangle on the right short side has one side = 5, and the "invisible" side is 15 - 10 = 5.
these 2 sides are hitting each other in a right angle and can therefore be used as baseline and height of the triangle.
so, the area of the this triangle is 5×5/2 = 12.5.
so the total area is
375 + 20 + 12.5 = 407.5

How do I figure this out
Answer:
x = 21Step-by-step explanation:
Given triangle is equilateral since all three angles marked as congruent.
It means each interior angle measures 60°.
The angle (5x + 15)° is exterior angle.
We know exterior angle measure is same as the sum of non-adjacent interior angles:
5x + 15 = 60 + 605x + 15 = 1205x = 120 - 155x = 105x = 105/5x = 21The explicit formula for a sequence is f(n)
What is the value of f(3)?
19 + 6n
Answer:
f(3) = 37
Step-by-step explanation:
If the formula for this arithmetic sequence is f(n) = 19 + 6n, then the value of f(3) is 19 + 6(3), or f(3) = 37

Solve the expression and find the value of x.
[tex] \frac{x + 1}{10} - \frac{3(x - 1)}{5} = 2 [/tex]
[tex]\large\underline{\sf{Solution-}}[/tex]
[tex]\sf \dfrac{x + 1}{10} - \dfrac{3(x - 1)}{5} = 2[/tex]
[tex]\sf\longmapsto \dfrac{x + 1}{10} - \dfrac{3x - 3}{5} = 2[/tex]
[tex]\sf\longmapsto \dfrac{(x + 1) - 2(3x - 3)}{10} = 2[/tex]
[tex]\sf\longmapsto \dfrac{x + 1 - (6x - 6)}{10} = 2[/tex]
[tex]\sf\longmapsto \dfrac{x + 1 - 6x + 6}{10} = 2[/tex]
[tex]\sf\longmapsto \dfrac{ - 5x + 7}{10} = 2[/tex]
[tex]\sf\longmapsto - 5x + 7 = 20[/tex]
[tex]\sf\longmapsto - 5x = 20 - 7[/tex]
[tex]\sf\longmapsto - 5x = 13[/tex]
[tex]\sf\therefore x = - \dfrac{13}{5} [/tex]
Hence, the value of x will be -13/5 respectively.
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
[tex]\frac{x + 1}{10} - \frac{3(x - 1)}{5} = 2 \\ [/tex]
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Take a look at the denominators. The denominators are 10, 5 & 1. Their LCM is 10. So, multiply the fractions on both the sides of the equation by 10.
[tex]\frac { x + 1 } { 10 } - \frac { 3 ( x - 1 ) } { 5 } = \frac{2}{1} \\ \frac{x + 1}{10} \times \frac{1}{1} - \frac{3x - 3}{5} \times \frac{2}{2} = \frac{2}{1} \times \frac{10}{10} \\ \frac{x + 1}{10} - \frac{6x - 6}{10} = \frac{20}{10} [/tex]
Now cancel the denominators (as they have the same value) & take the numerators.
[tex]x + 1 - (6x - 6) = 20 \\ [/tex]
Now, simplify it.
[tex]x + 1 - (6x - 6) = 20 \\ x + 1 - 6x + 6 = 20 \\ x - 6x + 1 + 6 = 20 \\ - 5x + 7 = 20 \\ - 5x = 13 \\ x = -\frac{13}{5} \\ \boxed{ \boxed{ \bf x = - \frac{13}{5} =\: - 2 \frac{3}{5} = - 2.6}}[/tex]

For the piecewise defined function f (x)=
3x-1 x<3
1/2 x + 7. x>3
what is the following is the value of f (6) ?
Answer:
10
Step-by-step explanation:
f(x)=f(6) means x=6
Now, as 6>3 we use the formula for x>3
Substituting 6 into 1/2x+7 we get,
1/2(6)+7
=3+7
=10
The value of function at x= 6 is 10.
What is Piecewise function?A piecewise-defined function in mathematics is one that is composed of several smaller functions, each of which has a certain interval of the domain it applies to. Instead of being a property of the function itself, piecewise definition is a means to express the function.
We have,
f(x) = 3x -1 , x<3
1/2x + 7, x>3
Now, for x = 6 which falls in condition x>3
f(6) = 1/2(6)+ 7
f(6) = 3 + 7
f(6)= 10

Help please I going to get an f please help
Answer:
The answer is a.
Step-by-step explanation:
The equation formula is y=mx+b. M stands for the slope. B stands for the y-intercept. In the question, it says that your slope is 3/8 and that your y-intercept is -2. Remember, if it says (0, -2), and 0 is your x-coordinate, it means that it is a y-intercept. So, plug in the numbers into the formula and the equation should be: y=3/8x-2

since we know that our x=0 then y=3(-13)^0

put it in mind that during the indices we learnt that any number to the power zero is 1 and any number to the power 1 it is the number itself so we can continue to say
y=3(1)

Which of the following describes the parabola with the equation y = 4x^2 − 12x + 9?
A. The axis of symmetry is x = 4 and the vertex is (4, −12).
B. The axis of symmetry is x = −1.5 and the vertex is (−1.5, 36).
C. The axis of symmetry is x = 0 and the vertex is (0, 9).
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).
Answer:
D. The axis of symmetry is x = 1.5 and the vertex is (1.5, 0).
Step-by-step explanation:
y=4x^2-12x+9:\quad \mathrm{Parabola\:with\:vertex\:at}\:\left(h,\:k\right)=\left(\frac{3}{2},\:0\right),\:\mathrm{and\:focal\:length}\:|p|=\frac{1}{16}
To find the vertex of this parabola, "complete the square:" Rewrite y = 4x2 - 12x + 9 in the form y = 4(x - h)^2 + k:
y = 4x^2 - 12x + 9 => y = 4(x^2 - 3x) + 9.
Now complete the square of x^2 - 3x: Take half of -3 and square the result, obtaining (-3/2)^2, or 9/4. Add 9/4 to x^2 - 3x and then subtract 9/4 from the result: We get x^2 - 3x + 9/4 - 9/4. Substitute this result back into
y = 4(x^2 - 3x) + 9: y = 4(x^2 - 3x + 9/4 - 9/4) + 9
and then rewrite the perfect square x^2 - 3 + 9/4 as the square of a binomial:
y = 4(x - 3/2)^2 - 9/4) + 9. This simplifies to:
y = 4(x - 3/2)^2 + 0.
Thus, the vertex is at (3/2, 0) and the axis of symmetry is x = 3/2. This agrees with Answer B.
Given : equation y = 4x^2 − 12x + 9
To Find :
A) The axis of symmetry is x = 0 and the vertex is (0,9).
B)The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
C)The axis of symmetry is x = 4 and the vertex is (4, -12).
D)The axis of symmetry is x = -1.5 and the vertex is (-1.5, 36).
Solution:
y = 4x² - 12x + 9
=> y = (2x)² - 2(2x)3 + 3²
=> y = (2x - 3)²
=> y = 4(x - 3/2)²
=> y = 4(x - 1.5)²
Axis of symmetry is x= 1.5
Vertex = (1.5 , 0)
The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
A Strong wind blows to the west at a speed of 38.7 mph relative to the ground causing a commercial plane to change course. What should be the plane's velocity in order to maintain a southward direction at a constant speed of 452 mph relative to the ground?
The speed of the plane is the rate of change of distance over time
The speed of the plane should be 453.65 mph southwest
The speed of the wind is given as:
[tex]\mathbf{S_w = 38.7mph}[/tex]
The expected speed of the plane is:
[tex]\mathbf{S_s = 452mph}[/tex]
So, the actual speed is calculated using the following Pythagoras theorem
[tex]\mathbf{S_{sw}^2 = S_w^2 + S_s^2}[/tex]
This gives
[tex]\mathbf{S_{sw}^2 = 38.7^2 + 452^2}[/tex]
[tex]\mathbf{S_{sw}^2 = 205801.69}[/tex]
Take square roots of both sides
[tex]\mathbf{S_{sw} = 453.65}[/tex]
Hence, the speed of the plane should be 453.65 mph southwest
