Answer: 10.88

Step-by-step explanation:

6.8 x 1.6 = 10.88

you can multiply them without the decimals first then when you got the answer, you can count how many decimal places are there and place a decimal place where shoud be

(4-2)^3 -3*4 =

(4-2) = 2, 2^3 = 8

3*4 =12

so you have 8-12 = -4

Answer is -4

form a 6 digit number divisible by 1 first 2 divisible by 2, first 3 digits divisible by 3, first 4 digits divisible by 4, first

Answer:

111111

Step-by-step explanation:

Digit 1: This can be any digit as all numbers are divisible by 1. I picked 1 because it was simplest.

Digit 2: The total needs to be divisible by 2, so I picked my total to be 2. I knew I already had 1 from the previous digit, so 2-1 =1 was my next digit.

Digit 3: The total must be divisible by 3, so I picked my total to be 3. I already had 2 from the two previous digits, so 3-1 = 1 was my next digit.

I hope you get the idea now, it follows the same pattern for the rest of the numbers.

Hopefully this helps, any questions let me know :)

Right Triangle Trig.

d1i1m1o1n [39]

The values are vx = $\frac{14\sqrt{3} }{\sqrt{2} }$ , vw = $\frac{14\sqrt{3} }{\sqrt{2} }$ and m∠x = 45°, for the given right angle diagram.

Step-by-step explanation:

The given is,

Right angled triangle XVW,

XW = 14 $\sqrt{3}$

m∠V = 90°

m∠W = 45°

Step:1

Given diagram is right angle triangle,

Trigonometric ratios for right angle is,

$sin$ ∅ $=\frac{Opp}{Hyp}$ ............................(1)

$cos$ ∅ $= \frac{Adj}{Hyp}$ .........................(2)

$tan$ ∅ $= \frac{Opp}{Hyp}$ ..........................(3)

Step:2

For the value of VX,

$sin$ ∅ $=\frac{VX}{XW}$

From given,

∅ = 45°

XW = 14 $\sqrt{3}$

Above equation becomes,

$sin$ 45 $=\frac{VX}{14\sqrt{3} }$

Where, Sin 45 = $\frac{1}{\sqrt{2} }$ ,

$\frac{1}{\sqrt{2} } = \frac{VX}{14\sqrt{3} }$

$VX = \frac{14\sqrt{3} }{\sqrt{2} }$

Step:3

For the value of VW,

$cos$ ∅ $=\frac{VW}{XW}$

From given,

∅ = 45°

XW = 14 $\sqrt{3}$

Above equation becomes,

$cos$ 45 $=\frac{VW}{14\sqrt{3} }$

Where, cos 45 = $\frac{1}{\sqrt{2} }$ ,

$\frac{1}{\sqrt{2} } = \frac{VW}{14\sqrt{3} }$

$VW = \frac{14\sqrt{3} }{\sqrt{2} }$

Step:4

For the value m∠x = a,

$tan$ a $=\frac{VX}{VW}$

From given,

VX = $\frac{14\sqrt{3} }{\sqrt{2} }$

VW = $\frac{14\sqrt{3} }{\sqrt{2} }$

Above equation becomes,

$tan$ a $=\frac{\frac{14\sqrt{3} }{\sqrt{2} } } {\frac{14\sqrt{3} }{\sqrt{2} } }$

$tan$ a = 1

a = $tan^{-1}$ (1)

a = 45°

m∠x = a = 45°

Step:5

Check for solution,

m∠v = m∠w + m∠x

= 45° + 45°

90° = 90°

Result:

The values are vx = $\frac{14\sqrt{3} }{\sqrt{2} }$ , vw = $\frac{14\sqrt{3} }{\sqrt{2} }$ and m∠x = 45°, for the given right angle diagram.
