Answer:

h = -6

Step-by-step explanation:

Use the quadratic formula

ℎ

=

−

±

2

√

2

h=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}

h=2a−b±b2−4ac​​

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

h^{2}-36=0

h2−36=0

a={\color{#c92786}{1}}

a=1

Please help me with this #7
Alex

\text{Given that,}\\\\\text{First term,}~ a_1 =  -8~~~~...(i)\\\\\text{12th term,}~ a_{12} = -52~~~...(ii)\\\\\text{Common difference is d.}\\\\(ii)\div(i):\\\\\dfrac{a_{12}}{a_1} = \dfrac{-52}{-8}\\\\\\\implies \dfrac{a_1 + (12-1)d}{a_1} = \dfrac{52}8\\\\\\\implies \dfrac{-8+11d}{-8} = \dfrac{52}8\\ \\\\\implies -8+11d = \dfrac{52(-8)}8\\\\\\\implies -8+11d = -52\\\\\\\implies 11d = -44\\\\\\ \implies d = \dfrac{-44}{11} = -4

\\\text{86th term,} ~a_{86} = a+ (86-1)d \\\\~~~~~~~~~~~~~~~~~~~~=-8+85d\\\\~~~~~~~~~~~~~~~~~~~~=-8+85(-4)\\\\~~~~~~~~~~~~~~~~~~~~=-348\\\\\text{Hence, the 86th term is}~  -348

Given the function,f(x)= /3x+3-3 , choose the correct transformation(s).
padilas [110]

Answer:

Horizontal Compression, Left 1, Down 3

A is correct

Step-by-step explanation:

Given: f(x)=\sqrt{3x+3}-3

The parent function of given function is square root function.

f(x)=\sqrt{x}

Shift 1 unit left

f(x)=\sqrt{x+1}

Horizontal compression

f(x)=\sqrt{3(x+1)}

Vertical down by 3 unit

f(x)=\sqrt{3x+3}-3

\sqrt{x}\rightarrow \sqrt{3x+3}-3

After above translation.

Hence, The function obtain from square root function after horizontal compression, left 1 and down 3
