What is the value of S4 for infinity sigma n=1 10(0.2)^n-1

A. 2.48
B. 12.48
C. 16
D. 24

Answer:

No. In order to be a right triangle, the lengths of the 2 smaller sides must equal the length of the longest side.

In other words, these 3 sides must work with the Pythagorean theorem.

A^2 + B^2 = C^2

25^2 + 30^2 is NOT 30^2

This is a triangle, just not a right triangle.

Answer:

405 in^2

Step-by-step explanation:

Given data

Height= 27in

Circumference= 47.1 in

let us find the radius and the diameter of the base of the cylinder

from

C=2πr

47.1= 2*3.142*r

47.1= 6.284r

r= 47.1/6.284

r= 7.5 in

Diameter= 2r

D= 7.5*2

D= 15in

Hence the area of the cross-section

=H*D

=27*15

=405 in^2

Answer:

[tex] \displaystyle \text C)\csc( {225}^{ \circ } )= - \sqrt{2} [/tex]

Step-by-step explanation:

we want to figure out the exact value of the following:

[tex] \displaystyle \csc( {225}^{ \circ} ) [/tex]

recall that,

[tex] \displaystyle \csc( \theta ) = \frac{1}{ \sin( \theta)} [/tex]

we are given [tex]\theta=225°[/tex]

substitute:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \sin( {225}^{ \circ} )} [/tex]

225° belongs to Q:III which we can clearly acquire from unit circle so,

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{1}{ \dfrac{ - \sqrt{2} }{2} } [/tex]

By simplifying complex fraction we get:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } [/tex]

notice that, what we acquired isn't in the option so multiply it by √2/√2

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2}{ - \sqrt{ 2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } [/tex]

simplify multiplication:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - \sqrt{ 4} } [/tex]

simplify square:

[tex] \displaystyle \csc( {225}^{ \circ } )= \frac{2 \sqrt{2} }{ - 2} [/tex]

reduce fraction:

[tex] \displaystyle \csc( {225}^{ \circ } )= - \sqrt{2} [/tex]

hence,

our answer is C

Answer and Step-by-step explanation:

8. We want to solve for a of the trapezoid area formula.

A = [tex]\frac{h}{2} (a + b)[/tex]

First off, we need to multiply both sides by [tex]\frac{2}{h}[/tex] to cancel out the [tex]\frac{h}{2}[/tex].

[tex]\frac{2A}{h}[/tex] = a + b

Now, we need to subtract b from both sides.

[tex]\frac{2A - b}{h}[/tex] = a

We get the answer to be:

I. a = [tex]\frac{2A - b}{h}[/tex]

#teamtrees #PAW (Plant And Water)

Answer:

Yes

Step-by-step explanation:

It lies on the circle because the radius is 2 and the point goes down two units just like the radius

Answer:

yes

Step-by-step explanation:

the radius extends out 2 points throughout the entire circle therefore -2 will be reached as it is 2 units below the center of (4, 0)

Answer:

2

Step-by-step explanation:

add 16 to zero

4x2=16

Divide 4x by 2 and 16 by two

4x=8

divide 8 by 4

x=2

Answer:

x = ± 2

Step-by-step explanation:

Given

4x² - 16 = 0 ( add 16 to both sides )

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take the square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2

solutions are x = - 2, x = 2

There is no step-by-step explanation because it's a graph. Well, it's how I did it. Therefore, the graph in the picture that I'm about to post will be your answer.

Answer:

64 inches or 64 pulgadas

Step-by-step explanation:

The formula for the perimeter of a rhombus is given as:

P = 4a

Where a = side length of the rhombus

From the above question, side length of the rhombus = 16 inches

Hence, Perimeter of the rhombus = 4 × 16 inches

= 64 inches

La fórmula para el perímetro de un rombo se da como:

P = 4a

Donde a = longitud del lado del rombo

De la pregunta anterior, la longitud del lado del rombo = 16 pulgadas

Por lo tanto, perímetro del rombo = 4 × 16 pulgadas

= 64 pulgadas

Answer:

x=7, y=9. (7, 9).

Step-by-step explanation:

-3x+y=-12

5x-2y=17

---------------

y=-12-(-3x)

y=-12+3x

y=3x-12

5x-2(3x-12)=17

5x-6x+24=17

-x+24=17

-x=17-24

-x=-7

x=7

y=3(7)-12

y=21-12

y=9
