Given 1 = 123° and 8 = 7z + 11.<br><br> What is the value of z, if lines a and b are parallel?

Serga [27]

Answer:

z=16

Step-by-step explanation:

We know for sure that since A and B are parallel that 1, 4, 5, and 8 are equal.

So then the equation is simply 123=7z+11---> 7z=112----> z=16

Start with

$1=\dfrac{1}{n^2}+\dfrac{n^2-4n-5}{3n^2}$

We observe that both fractions are not defined if $n=0$ . So, we will assume $n \neq 0$ .

We multiply both numerator and denominator of the first fraction by 3 and we sum the two fractions:

$1=\dfrac{3}{3n^2}+\dfrac{n^2-4n-5}{3n^2} = \dfrac{n^2-4n-2}{3n^2}$

We multiply both sides by $3n^2$ :

$n^2-4n-2=3n^2$

We move everything to one side and solve the quadratic equation:

$2n^2+4n+2=0 \iff 2(n^2+2n+1)=0 \iff 2(n+1)^2=0 \iff n+1=0 \iff n=-1$

We check the solution:

$1=\dfrac{1}{1}+\dfrac{1+4-5}{3} \iff 1 = 1+0$

which is true

Answer:

37.68cm

Step-by-step explanation:

C = 2 $\pi$ r

C = circumference

$\pi$ = the constant pi (3.14)

r = radius of the circle (6cm)

d = diameter of the circle (12cm)

d = 2r

C = 2 · 3.14 · 6

C = 37.68cm

Tell whether the points appear to represent a linear function, an exponential function, or neither? Explain please.

mario62 [17]

Answer:

Exponential

Step-by-step explanation:

Linear is easy to remember because it goes in a straight LINE.

Only other option is a quadratic and this does not create a parabola
