The correct answer is B. $210
Answer:
<em>No values of x can make f(x)=6</em>
Step-by-step explanation:
Equation with Absolute Value
The absolute value of a number is always positive. That condition must be met when solving equations. Any condition that goes against the rule, must be discarded and not part of the solution.
The function provided in the question is:
We need to find the value(s) of x that make:
f(x)=6
It needs to solve the equation:
Subtracting 1:
Dividing by -0.5:
We reach to this equation to solve:
As stated above, the absolute value is always positive, and the equation forces the absolute value to be negative. There is no possible value of x that makes the absolute value negative, thus:
No values of x can make f(x)=6
Answer:
602 in^2
Step-by-step explanation:
To find volume, multiply length, width, and height. In this case, it is 5, 14, and 8 3/5. I used a calculator, but if not, solve it using regular multiplication. First 5 times 14 since that is easier to get out of the way, then 8 3/5, and it is easiest to treat a fraction as a decimal when multiplying, in this case it would be 0.6. I am not going to explain how I got that since you were asking how to find volume.
Answer:
You will obtain a complex number rotated by an angle of 45 degrees (counterclockwise) with a modulus scaled by √2
Step-by-step explanation:
In order to see the effect of multiplying z by 1 + i, you can use the representation of complex numbers in the <em>Polar Form</em>. This representation gives you the angle formed by the complex number and the real axis and the distance from the origin to the point.
Let z=a+ib represent a complex number.<em> The Polar</em> Form is:
z = |z| (Cosα + iSinα)
Where |z| is the modulus of the complex number and α is the angle formed with the real axis.
|z| = √a²+b²
α= arctan (b/a)
The multiplication in<em> Polar Form</em> is:
Let Z0 and Z1 represent two complex numbers
Z0= |Z0| (Cosα + iSinα)
z1= |z1|(Cosβ + iSinβ)
The multiplication is:
Z0.Z1 = |Z0||Z1| [Cos(α+β) + i Sin(α+β)]
Notice that when you multiply complex numbers, you are adding angles and multiplying modulus. The addition of angles can be seen as a rotation of the complex number on the plane and the multiplication of modulus can be seen as changing the modulus of the complex number.
The given number 1+i in the Polar Form is:
z = |z| (Cosα + i Sinα)
|z| = √1²+1² = √2
α = arctan(1/1) = 45°
Therefore, you will obtain a complex number rotated by an angle of 45 degrees with a modulus scaled by √2
Your answer is 8/5
If you plug it in, you get:
8/(2+3)
Add the 2 and 3 and you’ll get
8/5
