A driver in a car traveling at a speed of 21.8 m/s sees a cat 101 m away on the road. How long will it take for the car to accel
Bogdan [553]

Answer:

t = 9.08 sec

Explanation :

This requires the use of the kinematic equations.

u = initial velocity = 21.8 m/s

v = final velocity = 0

t = time = what we're trying to find.

So we use the equation that relates d, u, v and t. This is

d = distance = 99m

d = \frac{t*(u+v)}{2}

and since v = 0 this reduces to d = \frac{tu}{2}

which rearranges to t = \frac{2d}{u}

t = \frac{2*99}{21.8} =9.08 seconds

t = 9.08 sec

A solid figure is
Len [333]

Answer: 4 feet.

Step-by-step explanation:

Their is one rectangular prison divided into two.

The volume of the first one is

V1= L X H X W=80.

Volume of the second one is

V2= L X H X W

V2= 6 X H X 5

V2 = 30H

Now from the question, the total volume is 200cubic feet which means V1 + V2 = 200, recall that V1=80 and V2=30H, so we say;

80+30H=200, collecting the like term we have, 30H=200-80.

30H=120, divide both side by 30

30H/30=120/30

H= 4feet.

Height is 4feet.

Two numbers total 10, and there difference is 12. Find a smaller of the two numbers.
Olenka [21]

Answer:

There doesn't seem to be numbers to answer that, do you have the question right? If it was a difference of 18, for example, the numbers would be 64 and 36.

Step-by-step explanation:

Find 2 numbers that added together, equal 10.

91

82

73

64

55

46

37

28

19

Then subtract them by their opposites. Find the numbers with the difference of 12.

91 - 19 = 72

82 -  28 = 54

73 - 37 = 36

64 - 46 = 18

55 - 55 = 0

46 - 64 = -18

37 - 73 = -36

28 - 82 = -54

19 - 91 = -72

There is no numbers with the difference of 12.

If it was a difference of 18, for example, the numbers would be 64 and 36.

5 Exam-style ABCD is a kite.
Mnenie [13.5K]

let's recall that in a Kite the diagonals meet each other at 90° angles, Check the picture below, so we're looking for the equation of a line that's perpendicular to BD and that passes through (-1 , 3).

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of BD

y = \stackrel{\stackrel{m}{\downarrow }}{3}x-1\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

\stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{3\implies \cfrac{3}{1}} ~\hfill \stackrel{reciprocal}{\cfrac{1}{3}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{1}{3}}}

so we're really looking for the equation of a line whose slope is -1/3 and passes through point A

(\stackrel{x_1}{-1}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies -\cfrac{1}{3} \\\\\\ \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-\stackrel{y_1}{3}=\stackrel{m}{-\cfrac{1}{3}}[x-\stackrel{x_1}{(-1)}]\implies y-3=-\cfrac{1}{3}(x+1) \\\\\\ y-3=-\cfrac{1}{3}x-\cfrac{1}{3}\implies y=-\cfrac{1}{3}x-\cfrac{1}{3}+3\implies y=-\cfrac{1}{3}x+\cfrac{8}{3}
