v =  \frac{d}{t}
V = 100m/65s

that's your answer
and it'll be in m/s

hope it helps!

The speed is <u>equal </u>to the distance travelled  <u>divided</u> by the time taken:

Speed = \frac{Distance}{Time}

All we do is use the number for distance, and the number for time from the question.

Distance = 100 meters

Time        = 65 seconds.


Now lets <u>divide </u>the Distance by the Time, to get the speed:

Speed = \frac{Distance}{Time}

Speed = \frac{100}{65} = 1.5


The units of the speed will be: meters / seconds,    or m/s   for short, because we divide the distance (in meters) by the time (in seconds)


Answer:

1.5 m/s

find to consecutivephone number such that five times the smaller number plus 3 times the greater number make 59 hint let the num
Scorpion4ik [409]

Answer:

x = 7 is the answer for the smaller number

7 + 1 = 8 is the answer for the larger number

Step-by-step explanation:

LET x and  x+1 be the two numbers here, as your hint suggests.

5x + 3(x+1) = 59

5x + 3x+3 = 59

8x = 59-3

8x = 56

/8      /8

--------------------------

x = 56/8 ---> x = 7

x = 7 is the answer for the smaller number

7 + 1 = 8 is the answer for the larger number

Check:

5 * 7 + 3 * 8 = 59

35 + 24 = 59

59 = 59 CORRECT

Algebraically determine the x-intercepts of this function. Please show work.
WINSTONCH [101]
To determine x intercept, put y=0

<span>x^4 - 10x^2 + 9  = 0
</span>
<span>x^4 - 9x^2  - x^2 + 9 = 0

x^2(x^2 - 9) - 1(</span><span>x^2 - 9) = 0

(</span><span>x^2 - 9)(x^2-1) =0

x^2 - 9 = 0
⇒ x^2 = 9
⇒x = +3, -3

x^2 - 1 = 0
x^2 = 1
x = +1, -1

X intercepts are -3, -1, 1, 3
