Solve for X:<br> x/5 + 4 = 6
STALIN [3.7K]

Answer:10

Step-by-step explanation:

X/5+4 = 6

X/5 =2

(Multiply 5 on both sides to get x alone)

2(5) = 10

X = 10

Logarithms are studied for which of the following​ reasons? A. To help in solving exponential equations when relating the bases
skad [1K]

Answer:

To help in solving exponential equations when relating the bases cannot be used

Step-by-step explanation:

Recall an equation of the form

a^{x}=b\\ from the expression a^{x}\\, a\\ is the base and the power is {x}\\.

a\neq b\\ it is impossible to carryout the operation since the bases are not equal.

This is where we implore the help of logarithm which help us to bring the base to a come base i.e using the property below

loga^{x}=logb\\x=\frac{logb}{loga} \\.

Hence we can conclude that logarithm helps in solving equations when bases cannot easily be related.

The base of a solid in the region bounded by the parabola x2 + y = 4 and the line x + y = 2. Cross sections of the solid perpend
Evgen [1.6K]

Answer:

volume of the solid is 3.180

Step-by-step explanation:

given data

line x + y = 2

parabola  x2 + y = 4

to find out

the volume of the solid

solution

we draw a graph between line and parabola as show in fig given below attach

line cut at (-1,3) and (2,0)

so the length of diameter is ( 4 - x²) - (2 - x)

and radius of this semi circle will be ( 4 - x² - 2 + x ) /2

radius = (-x² + x + 2 ) /2

and r(x) will be  =  (-x² + x + 2 ) /2

and A(x) will be  = π ( r(x)² ) /2

we will integrate from -1 to 2

= \int_{-1}^{2}A(x))

= \int_{-1}^{2}(π ( (-x² + x + 2 ) /2)² ) /2))

= 81π / 20

volume of the solid is 3.180
