Slope is the change in Y over the change in X:

Slope = (6 - -8) / (5 - -3)

Slope = (6+8) / (5+3)

Slope = 14/8

Slope = 7/4

Answer:

7/6

Step-by-step explanation:

Use the Formula: y2-y1/x2-x1 = 6-(-8)/5-(-3) = 6+8/5+3 = 14/8 = 7/6

The current (I) varies directly as the voltage (V) in an electric circuit. If the current is 4 amperes when the voltage is 100 v

Margarita [4]

$\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
\\
&& y={{ k }}x
\end{array}\\\\
-----------------------------\\\\$

$\bf \textit{l varies directly to V}\implies l=kV
\\\\\\
\textit{now, we also know that }
\begin{cases}
l=4\\
V=100
\end{cases}\implies 4=k100
\\\\\\
\cfrac{4}{100}=k\implies \cfrac{1}{25}=k\impliedby \textit{constant of variation}
\\\\\\
thus\implies l=\cfrac{1}{25}V
\\\\\\
\textit{what is the current when the voltage is 75?}\qquad l=\cfrac{1}{25}\cdot 75$

What is mArc S U? 49° 77° 98° 161°

zvonat [6]

Answer:

77°

Step-by-step explanation:

Find the diagram atached

From the figure

m<T = 1/2(arcRU - arcSU)

m<T = 1/2(119-arcSU)

21 = 1/2(119-arcSU)

21*2 = 119-arcSU

42 = 119-arcSU

arcSU = 119 - 42

arcSU = 77degrees

Hence the meaasure of arcSU is 77degrees
