Answer: See step-by-step below.

Step-by-step explanation:

First we need to solve the equation, 16x + 16x - 1 = 10.

16x + 16x - 1 = 10

32x-1 = 10

Whatever we do on one side, we have to do on the other.

So, we will add 1 to both sides.

32x - 1 + 1 = 10 + 1

Simplify.

32x = 11

x = 11/32

So, 22x = 22(11/32)

= 121/16

 =  7 9/16

When you multiply a pair of conjugates you get a real number
marusya05 [52]

Answer: The complex conjugate has a very special property. Consider what happens when we multiply a complex number by its complex conjugate. We find that the answer is a purely real number  it has no imaginary part. This always happens when a complex number is multiplied by its conjugate the result is real number.

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers

Step-by-step explanation: Every complex number has a complex conjugate. The complex conjugate of a + bi is a - bi. For example, the conjugate of 3 + 15i is 3 - 15i, and the conjugate of 5 - 6i is 5 + 6i.

8. Find GH,<br> E<br> 3-4<br> HY<br> -<br> H<br> 2<br> 3x - 4<br> G<br> SI<br> F<br> 9x - 59<br> D
Ostrovityanka [42]

Answer:

GH= 47

Step-by-step explanation:

2(3x - 4) = 9x - 59

6x - 8 = 9x - 59

6x - 9x =  - 59  + 9

\cfrac{ - 3x}{ - 3}  =  \cfrac{ - 51}{ - 3}

x = 17

gh = 3(17)  - 4

51 - 4

= 47

Work out the surface area of a cylinder when the height = 18cm and the volume = 1715cm cubed
lara [203]

Answer:

813.4 cm² (nearest tenth)

Step-by-step explanation:

<u>Volume of a cylinder</u>

\sf V=\pi r^2 h \quad\textsf{(where r is the radius and h is the height)}

Given:

  • h = 18cm
  • V = 1715 cm³

Use the Volume of a Cylinder formula and the given values to find the <u>radius of the cylinder</u>:

\implies \sf 1715=\pi r^2 (18)

\implies \sf r^2=\dfrac{1715}{18 \pi}

\implies \sf r=\sqrt{\dfrac{1715}{18 \pi}

<u>Surface Area of a Cylinder</u>

\sf SA=2 \pi r^2 + 2 \pi r h \quad\textsf{(where r is the radius and h is the height)}

Substitute the given value of h and the found value of r into the formula and solve for SA:

\implies \sf SA=2 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)^2 + 2 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)(18)

\implies \sf SA=2 \pi \left(\dfrac{1715}{18 \pi} \right) + 36 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)

\implies \sf SA=\dfrac{1715}{9} + 36 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)

\implies \sf SA=813.3908956...

Therefore, the surface area of the cylinder is 813.4 cm² (nearest tenth)
