Given the graphs of f(x) = -x + 2 and g(x) = 5x – 4, what is the solution to the equation f(x) = g(x)?

Stels [109]

Answer:

c) 1

Step-by-step explanation:

f(x) = g(x)

-x+2 = 5x-4

+x +x

2 = 6x -4

+4 +4

6 = 6x

(divide both sides by 6)

1 = x

What is the measure in radians for the central angle of a circle whose radius is 5 and intercepted arc length is 7.2? Round your

Olegator [25]

Answer:

$0.46\pi\ radians$

Step-by-step explanation:

step 1

Find the circumference

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=5\ units$

assume

$\pi=3.14$

substitute

$C=2(3.14)(5)=31.4\ units$

step 2

Find the measure in radians for the central angle of a circle whose radius is 5 and intercepted arc length is 7.2 units

Remember that

The circumference of $31.4\ units$ subtends a central angle of $2\pi \ radians$

using proportion

Let

x-----> the central angle in radians

$\frac{2\pi}{31.4}=\frac{x}{7.2} \\ \\x=2\pi (7.2)/31.4\\ \\x=0.46\pi\ radians$

Simply (m^3np^-3)^3(mn^4p^2)

Tamiku [17]

Answer:

$=\frac{m^{10}n^7}{p^7}$

Step-by-step explanation:

$(m^3np^-^3)^3(mn^4p^2)\\\\\mathrm{Remove\:parentheses}:\quad \left(a\right)=a\\=\left(m^3np^{-3}\right)^3mn^4p^2\\\\\left(m^3np^{-3}\right)^3\quad :\quad m^9n^3p^{-9}\\\\=m^9n^3p^{-9}mn^4p^2\\\\\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times\:a^c=a^{b+c}\\\\m^9m=\:m^{9+1}\\\\=n^3p^{-9}m^{9+1}n^4p^2\\n^3n^4=\:n^{3+4}\\\\=n^3p^{-9}m^{10}n^4p^2\\\\\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times\:a^c=a^{b+c}\\=p^{-9}m^{10}n^{3+4}p^2\\\\=p^{-9}m^{10}n^7p^2\\\\=m^{10}n^7p^{-9+2}$

$=m^{10}n^7p^{-7}\\\\=m^{10}n^7\frac{1}{p^7}\\\\\frac{1\times\:m^{10}n^7}{p^7}\\\\=\frac{m^{10}n^7}{p^7}$
