What is the value of the fourth term in a geometric sequence for which a1 = 30 and r = 1/2?.
Mariana [72]
\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=30\\
r=\frac{1}{2}\\
n=4
\end{cases}\implies a_4=30\left( \frac{1}{2} \right)^{4-1}

HELP ASAP!! PLZ!!<br><br> Find the value of x in the triangle shown below
Ghella [55]

Answer:

x=50

Step-by-step explanation:

since its an isosceles triangle, both of the base angles are going to be the same. Since all of a triangle's angles combined equal 180, and you already have one angle, subtract the 80 from 180.

this leaves you with 100. since there are two angles left, divide 100 by two and thats the value of x

hope this helps!! :)

In parallelogram ABCD , m∠A=(2x)° and m∠B=(5x+5)° . The figure shows parallelogram A B C D with vertices named clockwise from bo
lara [203]

Answer:

The measure of angles of parallelogram are

∠A = 50° ,

∠B = 130° ,

∠C = 50° ,

∠D = 130°

Step-by-step explanation:

Given as for a parallelogram :

The vertices of parallelogram is A B C D in clockwise

The measure of angle A = ∠A =  ( 2 x )°

The measure of angle B =  ∠B =  ( 5 x + 5 )°

Now, for a parallelogram , the sum of measure of all four angles = 360°

<u>From The property of Parallelogram</u>

A ) The adjacent angles are supplementary

So, ∠A + ∠B =  180°

Or, ( 2 x )° + ( 5 x + 5 )° = 180°

Or, ( 7 x + 5 )° = 180°

Or , ( 7 x )° = 180° - 5°

Or , ( 7 x )° = 175°

∴   x = \frac{175}{7}

I.e x = 25°

So,  ∠A =  ( 2 x )° =  ( 2 ×25° )

I.e , ∠A = 50°

 ∠B =  ( 5 x + 5 )°

Or, ∠B =  ( 5 ×25° + 5 )°

I.e ,  ∠B = 130°

B ) The opposite angles of parallelogram is equal

   So,  ∠C =  ∠A = 50°

I,e   ∠C = 50°

And ∠D = ∠B = 130°

I.e  ∠D = 130°

Hence The measure of angles of parallelogram are ∠A = 50° , ∠B = 130° , ∠C = 50° , ∠D = 130°  Answer

(x^-4)^5 <br> please simplify the expression
pogonyaev
(x ^{-4} )^{5}

Apply exponent rule :

(a^b)^c = a^ ^{b.c}

=x ^{(-4)*5}

(-4)*5

= - 20

Apply exponent  rule :

a ^{-b} =  \frac{1}{a^b}

=  \frac{1}{x ^{20} }

hope this helps!
