Answer:

Length of the diagonal = 1.73 cm

Step-by-step explanation:

Side of cube = 1 cm

Length of diagonal = x = ?

The formula used to find length of diagonal of cube is: [tex]Diagonal=\sqrt{3}s[/tex] where s is length of side of cube.

We have s = 1

So, Length of Diagonal will be:

[tex]Length\:of\;Diagonal=\sqrt{3}s\\Length\:of\;Diagonal=\sqrt{3}(1)\\Length\:of\;Diagonal=1.73[/tex]

So, Length of the diagonal = 1.73 cm

Answer:

62

Step-by-step explanation:

The value of measure of ∠NPQ will be;

⇒ ∠ NPQ = 118°

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The Quadrilateral MNPQ is shown.

Here, Quadrilateral MNPQ is an parallelogram.

So, By definition of parallelogram we have;

⇒ ∠ NMQ + ∠ NPQ = 180°  ..(I)

Since, We have;

⇒ ∠ NMQ = 30° + 32°

                = 62°

So, By equation (i),

⇒ 62 °+ ∠ NPQ = 180°

⇒ ∠ NPQ = 180  - 62

⇒ ∠ NPQ = 118°

Thus, The value of measure of ∠NPQ = 118°

Answer:

Step-by-step explanation:

Answer:

The geometric series is [tex]8,\frac{8}{3} ,\frac{8}{9},\frac{8}{27},\frac{8}{81}[/tex]

The sum of the geometric series is 12.06

Step-by-step explanation:

First term of geometric series = 8

Common Ratio = 1/3

The formula used to find next term is: [tex]a_n=a_1r^{n-1}[/tex]

Our series has five terms, so we need to find 2nd, 3rd, 4th and 5th term

2nd term is:

[tex]a_n=a_1r^{n-1}\\a_2=8(\frac{1}{3})^{2-1}\\a_2=8(\frac{1}{3})^{1}\\a_2=\frac{8}{3}[/tex]

3rd term is:

[tex]a_n=a_1r^{n-1}\\a_3=8(\frac{1}{3})^{3-1}\\a_3=8(\frac{1}{3})^{2}\\a_3=\frac{8}{9}[/tex]

4th term is:

[tex]a_n=a_1r^{n-1}\\a_4=8(\frac{1}{3})^{4-1}\\a_4=8(\frac{1}{3})^{3}\\a_4=\frac{8}{27}[/tex]

5th term is:

[tex]a_n=a_1r^{n-1}\\a_5=8(\frac{1}{3})^{5-1}\\a_5=8(\frac{1}{3})^{4}\\a_2=\frac{8}{81}[/tex]

So, The geometric series is [tex]8,\frac{8}{3} ,\frac{8}{9},\frac{8}{27},\frac{8}{81}[/tex]

Now, Finding the sum of geometric series

The formula used is: [tex]S_n=\frac{1-r^n}{1-r}[/tex]

We have n =5, r=1/3

[tex]S_n=\frac{a(1-r^n)}{1-r}\\S_5=\frac{8(1-\frac{1}{3}^5)}{1-\frac{1}{3} }\\S_5=\frac{8(1-\frac{1}{243})}{1-\frac{1}{3} }\\S_5=\frac{8(\frac{243-1}{243})}{\frac{3-1}{3} }\\S_5=\frac{8(\frac{242}{243})}{\frac{2}{3} }\\S_5=\frac{8(0.995)}{0.66}\\S_5=12.06[/tex]

So, The sum of the geometric series is 12.06

Answer:

(8, - 2 )

Step-by-step explanation:

A translation of 4 units right means add 4 to the x- coordinate

A translation of 5 units up means add 5 to the y- coordinate

(x, y ) → (x + 4, y + 5 ) ← translation rule, then

(4, - 7 ) → A'(4 + 4, - 7 + 5 ) → A'(8, - 2 )

Step-by-step explanation:

3000 is the base amount of money. (1+.02) represents an increase of 2% in interest each year. (1+.02)^n-2 ; where n equals her age today. So, n-2 is the time since the money was invested, or 16.

Answer:

19 inches

Step-by-step explanation:

Given data

The length of the subway is 855 miles.

we are told that 1 inch represents 45 miles on map

Required

we want to find the length of 855 miles in inches

Let us do the conversion from miles to inches

1 inches = 45 miles

x inches=  855 miles

cross multiply we have

x= 855/45

x= 19 inches

Hence the length on the map is 19 inches

Answer:

step by step below

Step-by-step explanation:

(cscA+1).(1-sinA)=cosA.cotA

(1/sinA +1).(1-sinA) = 1/sinA*(1 - sinA) + 1*(1-sinA)

                             = 1/sinA - 1  + 1 - sinA

                             = 1/sinA - sinA

                             = (1 - sin²A) / sinA

                             =cos²A / sinA

                             = cosA*cosA / sinA

                             =cosA*cotA

Answer:

The solution to the equation is:

[tex]x=4,\:x=\frac{3}{2}[/tex]

Step-by-step explanation:

Given the equation

[tex]3\left(x-4\right)\left(2x-3\right)=0[/tex]

Using the zero factor principle

if ab=0, then a=0 or b=0 (or both a=0 and b=0)

[tex]x-4=0\quad \mathrm{or}\quad \:2x-3=0[/tex]

now solving

[tex]x - 4 = 0[/tex]

adding 4 to both sides

[tex]x - 4 + 4 = 0 + 4[/tex]

simplifying

[tex]x = 4[/tex]

and also solving

[tex]2x - 3 = 0[/tex]

adding 3 to both sides

[tex]2x - 3 + 3 = 0 + 3[/tex]

simplifying

[tex]2x = 3[/tex]

divide both sides by 2

[tex]\frac{2x}{2}=\frac{3}{2}[/tex]

simplifying

[tex]x=\frac{3}{2}[/tex]

Therefore, the solution to the equation is:

[tex]x=4,\:x=\frac{3}{2}[/tex]

Answer:

The system has no solutions

Step-by-step explanation:

Here, we want to solve the given equation systems

we can simply rewrite the second equation as;

y = 7-8x

So, let’s equate the two y

-8x + 6= 7-8x

As we can see, we have -8x on both sides of the equation and this means that there is no solution to system

This is because no value of x will make it that the addition of 6 to -8x will

be same as that of adding 7

Answer:

Pr/ok

Step-by-step explanation:

The ratio of cos P for the right-triangle PQR is PR/QR.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x
