Simplify the expression.​

Answers

Step-by-step explanation:

since all base numbers have the same exponent, we can combine the base numbers first and then apply the exponent :

(12×45×50)^(1/3) = 27000^(1/3)

and remember what a 1/... exponent means : it means the root of the ... degree.

so, here we need a cubic root or a root of the third degree

[tex] \sqrt[3]{27000} = 30[/tex]

What are the domain and range of f(x) = (one-sixth) Superscript x + 2?

domain: Left-brace x vertical-line x greater-than negative one-sixth right-brace; range: {y | y > 0}
domain: Left-brace x vertical-line x greater-than one-sixth right-brace; range: {y | y > 2}
domain: {x | x is a real number}; range: {y | y > 2}
domain: {x | x is a real number}; range: {y | y > –2}

Answers

The domain and range of the function is domain: {x | x is a real number}; range: {y | y > 2}

Given the exponential function expressed as;

[tex]f(x)=(\frac{1}{6})^x + 2[/tex]

The domain of the function will be the input value "x" for which it exists. For the function given, it exists for any value of "x".

Hence the domain of the function exists on all real numbers. Hence the domain in set notation is domain: {x | x is a real number}

The range of the function will be the output value "f(x)" for which it exists. For the function given, it exists for any value of f(x) greater than 2.

Hence the range of the function exists on any value of f(x) greater than 2. Hence the range in set notation is domain: {y | y >2}

Find the slope of line 2, which is parallel to line 1. Line i goes through the points
(-13, -6), (7, 15).

Answers

(-13, -6), (7, 15) = 1.05

Equation: y = 1.05x + 7.65.

The entered points belong to an increasing, linear function.

Answer:

m = rise / run = 21/20, or m = 1.05

Step-by-step explanation:

If the lines are parallel, their slopes are identical.  So we can find the slope of line 1 and know that it's also the slope of line 2.

From (-13, -6) to (7, 15), the x-component increases by 20 units from -13 to 7.  Thus, the "run" in m = rise / run is 20.  Likewise, the "rise" is 21.

Thus the slope in question is m = rise / run = 21/20

from module 2 to explain and answer correctly.

Answers

Step-by-step explanation:

error is in ∆ABC =~ ∆RST

because it is,

∆ABC =~ ∆RTS or ∆STR

because,

AB = RT

BC = TS

CA = SR

hope this answer helps you dear! take care.

The error is in labelling the triangles.

What are triangles?

A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.

Given are two ABC and RST

Since, Δ ABC ≅ Δ RST

That gives,

AB = RS

BC = TS

CA = RT

In figure,

AC has been equated to RS, which is wrong or incorrect because the corresponding side of AC is RT

The correct labelling will be

AB = RS = 5

BC = TS = 5

CA = RT = 5.5

Hence, The error is in labelling the triangles.
