This is the equation which you can add:
$[c + (3(c + 2))] + [5c]$

Simplify:
$[c + 3c + 6] + [5c] = 9c + 6$

And, that's your answer!

HELP! solve for p p+10/p-7=8/9

Nastasia [14]

$\frac{P+10}{P-7}$ = $\frac{8}{9}$

use the cross method solve the equation.

9P+90=8P-56
9P-8P=-56-90
P=-146

Hope this helps.

What is the approximate volume of the composite figure? Use 22/7 for pi. Round to the nearest hundredth.

Temka [501]

Answer:

188.57 cm³

Step-by-step explanation:

Half sphere = 1/2 volume sphere

Sphere = 4/3 * 22/7 * 3³

Sphere = 4/3 * 22/7 * 27/1

Sphere = 2376/21 = 113.14

113.14 / 2 = 56.57

Cone = 22/7 * 3² * h/3

Cone = 22/7 * 9/1 * 14/3

Cone = 2772/21 = 132

132 + 56.57 = 188.57 cm³

Use the equation below to answer the question.

JulijaS [17]

Answer:

The signa notation to represent the first five ten f(x) is given by $f(x)=\sum\limits^{5}_{n=1}a_n$

Step-by-step explanation:

Given sequence is -5, -9, 13...

Let f(x) be the given sequence and is denoted by

$f(x)=\{-5,-9,-13,...\}$

Let the first term be $a_1, 2^{\textrm{nd}}$ term be $a_3,...$

ie, $a_1=-5,a_2=-9, a_3=-13,...$

To find the common difference d:

$d=a_2-a_1$

$=-9-(-5)$

$=-9-(+5)$

$d=-4$

$d=a_3-a_2$

$=-13-(-9)$

$=-13+9$

$d=-4$

Therefore the common difference d is -4 for given sequence f(x) with $a_1=-5$ and d=-4, the seqence f(x) is an arithmetic sequence

By defintion of arithmetic sequence

$a_n=a+(n-1)d\hfill(1)$

Now to find $a_4, a_5$ :

put n=4 in equation (1)

$a_4=a+(4-1)d$

$a_4=-5+(3)(-4)$ [since a=-5, d=-4]

$=-5-12$

$a_4=-17$

in equation (1)

$a_5=a+(5-1)d$

$a_5=-5+(4)(-4)$ [since a=-5, d=-4]

$=-5-16$

$a_5=-21$

Therefore $a_4=-17$ and $a_5=-21$

Therefore $f(x)=\{-5,-9,-13,-17,-21,...\}$

Now to represent the sum of the first five terms of f(x) using sigma notation as below

$f(x)=\sum_{n=1}^5 a_n$

where $\sum_{n=1}^5 a_n=a_1+a_2+a_3+a_4+a_5$

$-5-9-13-17-21$

$\sum_{n=1}^5 a_n=-65$
