(Laws of Exponents with Whole Number Exponents LC)
Karolina [17]

The given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2.3 raised to the fifth power divided by 0.9 raised to the fourth power, all raised to the third power.

Write the expression in the mathematical form and solve:-

[ ( 2.9⁵) / ( 0.9 )⁴ ]³ = [ ( 2.9⁵) / ( 0.9 )⁴ ]³

                             =  [ ( 2.9 )¹⁵ / 0.9 )¹² ]

Therefore, the given expression will be equal to ( 2.3 )¹⁵ / ( 0.9 )¹². The correct option is D.

Find x and the measures of the indicated parts
frutty [35]
Given:

Two similar triangles AEB and ACD.

To solve for x, we can use ratio and proportion following the rule for similar triangles. 

So,

AE / AD = AB / AC

Substitute values,

AE = AD - DE
AE = 6 - 5
AE = 1

1 / 6 = 2 / (2 + x + 4)

Solve for x 

x = 6

then,

BC = x +4 = 6 + 4 = 10
AC = 2 + x + 4 = 12

Therefore, the measurements of the triangles are:

AE = 1 
BC = 10
AC = 12

A parabola has a vertex of (3,-2) and a y intercept of 7. what is the equation of this parabola
lorasvet [3.4K]

Answer:

Step-by-step explanation:

y=ax^2+bx+c

when x=0,y=7 so c=7

when x=3 then y=a*3^2+b*3+7=-2

9a+3b+7=-2

9a+3b=-2-7

9a+3b=-9

V(3,-2)

3=-b/2a

-b=3*2a

b=-6a

9a+3*(-6a)=-9

9a-18a=-9

-9a=-9

a=1

b=-6*1

b=-6a

b=-6

so y=x^2-6x+7
