The correct answer is A.) Obtuse.

When an angle is over 90° it is considered an obtuse angle. Any angle that measures under 90 is an acute angle.

Write an equation in point slope form for the line that passes through (-5,6) and (-3,-9).

Finger [1]

$\bf (\stackrel{x_1}{-5}~,~\stackrel{y_1}{6})\qquad
(\stackrel{x_2}{-3}~,~\stackrel{y_2}{-9})
\\\\\\
slope = m\implies
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-9-6}{-3-(-5)}\implies \cfrac{-9-6}{-3+5}\implies -\cfrac{15}{2}$

$\bf \begin{array}{|c|ll}
\cline{1-1}
\textit{point-slope form}\\
\cline{1-1}
\\
y-y_1=m(x-x_1)
\\\\
\cline{1-1}
\end{array}\implies y-6=-\cfrac{15}{2}[x-(-5)]\implies y-6=-\cfrac{15}{2}(x+5)
\\\\\\
y-6=-\cfrac{15}{2}x-\cfrac{75}{2}\implies y=-\cfrac{15}{2}x-\cfrac{75}{2}-6\implies y=-\cfrac{15}{2}x-\cfrac{87}{2}$

142/80 into mixed number

Cerrena [4.2K]

80 goes into 142 once, so one is our whole number. there are still 62 / 80 left, so we reduce this fraction. The answer is 1 $\frac{31}{40}$

Answer:

we get $\mathbf{gf(2)=-\frac{1}{3}}$

Step-by-step explanation:

We are given:

$f(x)=1-2x\\g(x)= \frac{1}{x}\\h(x)=x^3+1$

We need to find value of $gf(2)$

$gf(2)=g(f(2))$

First putting f(x) inside of g(x) and then putting x=2

$gf(x)=g(f(x))\\gf(x)=\frac{1}{1-2x}$

Now putting x=2 to find $gf(2)$

$gf(x)=\frac{1}{1-2x}\\gf(2)=\frac{1}{1-2(2)}\\gf(2)=\frac{1}{1-4}\\gf(2)=\frac{1}{-3}\\gf(2)=-\frac{1}{3}$

So, we get $\mathbf{gf(2)=-\frac{1}{3}}$

the table is 19 lb. 4 oz. the chair is 11 lb. 9oz. compare to the table, how much heavier are the two chairs?

Sever21 [200]

Answer:

3.875 lb

Step-by-step explanation:

Weight of table = 19lb 4 oz = 19-4/16 lb = 19.25 lb

Weight of each chair = 11 lb 9 oz = 11-9/16 lb = 11.5625 lb

Weight of 2 chairs = 2 x 11.5625 = 23.125 lb

Difference in weight between 2 chairs and one table

= 23.125 - 19.25

= 3.875 lb
