Since this is a right triangle, we can just use Pythagorean Theorem to solve for the side SU:

Length of Hypotenuse^2 = Length of First Leg^2 + Length of Second Leg^2
SU^2 = ST^2 + TU^2
SU = sqrt(ST^2 + TU^2)
SU = sqrt(42^2 + 56^2)
SU = sqrt(4900)
SU = 70

Therefore, the answer is is 70 centimeters.

Which table does not show a direct variation?
stiv31 [10]

Answer:

Table J

Step-by-step explanation:

A direct variation is a simple relationship between x and y.

When you are looking for the direct relationship you should use the formula for it y=kx, or you could just divide y over x (\frac{y}{x}).

<em><u>Analysing Table F:</u></em>

The relationship between x and y is 4.

\frac{-8}{-1}=4\\\\\frac{-4}{-1}=4\\\\\frac{0}{0}= origin\\\\\frac{4}{1}=4

The origin is fine and doesn't ruin the relationship.

<em><u>Analysing Table G:</u></em>

The relationship between x and y is 5.

\frac{5}{1}=5\\\\\frac{10}{2}=5\\\\\frac{15}{3}=5\\\\\frac{20}{4}=5

<em><u>Analysing Table H:</u></em>

The relationship between x and y is \frac{1}{3}.

\frac{0}{0}=origin\\\\\frac{1}{3}=\frac{1}{3}\\\\\frac{2}{6}=\frac{1}{3}\\\\\frac{3}{9}=\frac{1}{3}

Like I said before the origin doesn't ruin the relationship so it's fine.

<em><u>Analysing Table J:</u></em>

This one doesn't have a direct relationship between x and y.

\frac{1}{1}=1\\\\\frac{4}{2}=2\\\\\frac{9}{3}=3\\\\\frac{16}{4}=4

F(x) = x2 + 2x find f(-3)
spin [16.1K]

\longrightarrow{\blue{f(-3)\:=\:3}} 

\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}

f(x) =  {x}^{2}  + 2x

For f( - 3), substitute "-3" for each occurrence of "x".

f( - 3) = ( { - 3})^{2}  + 2( - 3)

= ( - 3 \times  - 3) - 6

= 9 - 6

= 3

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s t)(-7)? A. -439 B. -141 C. 153 D. 443
Ulleksa [173]
Answer: Option A -439

(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439
