Answer:

-\frac{3}{5}

Step-by-step explanation:

Use the slope formula:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}

Slope is the change in the y values over the change in the x values. Insert values:

(-3_{x_{1}},4_{y_{1}})\\\\(7_{x_{2}},-2_{y_{2}})\\\\\frac{-2-4}{7-(-3)}

Simplify:

\frac{-2-4}{7+3}=\frac{-6}{10} =-\frac{3}{5}

Therefore, the slope is -\frac{3}{5}.

valentina_108 [34]

Answer: 87.7^{\circ}


Step-by-step explanation:

Height of the building AB= 443 meters

Distance between the building and the agent at the ground BC= 18 meters

Let x be the angle the agent should shoot his laser gun

Since ΔABC is a right triangle, then

\tan\ x=\frac{AB}{BC}

\Rightarrow\tan\ x=\frac{443}{18}\\\Rightarrow\tan\ x=24.6111\\\Rightarrow\ x=\tan^{-1}(24.61)\\\Rightarrow\ x=87.67^{\circ}\approx87.7^{\circ}

Can someone help me?
Kitty [74]

Answer:

see explanation

Step-by-step explanation:

Given the width is \frac{1}{3} of the length, then

y - 4 = \frac{1}{3}(2y + 6)

Multiply through by 3 to clear the fraction

3y - 12 = 2y + 6 ( subtract 2y from both sides )

y - 12 = 6 ( add 12 to both sides )

y = 18

Thus

length = 2y + 6 = 2(18) + 6 = 36 + 6 = 42 in

width = y - 4 = 18 - 4 = 14 in

Niobium-91 has a half-life of 680 years. After 2,040 years, how much niobium-91 will remain from a 300. 0-g sample? 3 g 18. 75 g
alekssr [168]

Answer:

Amount of Niobium-91 initially

= 300/91 =3.2967mol

2040 years = 3 ×680 = 3 half-lives

therefore, amount left = 0.4121mol

mass of Niobium-91 remaining = 0.4121 ×91 =37.5g
