5 0

Answer:

90 m

Step-by-step explanation:

65 km = 65000m

1 hour = 3600 secs

speed in meters = 65000/3600

= 18 m / sec

Distance traveled in 5 secs = 18*5

= 90 m

Multiply and simplify. (2x - 1)(6x - 7)
Kryger [21]

Answer:

D) 12x² - 20x + 7

Step-by-step explanation:

Use FOIL when multiplying 2 binomials...

FOIL is Firsts, Outsides, Insides, Lasts.  It's the order in which you multiply the numbers in the binomials...

(2x - 1)(6x - 7)    

Firsts:  (2x)(6x) = 12x²

Outsides:  (2x)(-7) = -14x

Insides:  (-1)(6x) = -6x

Lasts:  (-1)(-7) = 7

Now add them up...

12x² - 14x - 6x + 7

    12x² - 20x + 7

Answer with Step-by-step explanation:

16 19 21 26 27 29 34 35 35 39 40 41 42 50 50 52 57 60 75 76 78 81 84

the data is already arranged in ascending order

Min=16

Max=84

The quartiles for the odd set of data is given by

Qi=\dfrac{i(n+1)}{4}\ th\ term

where n is the number of elements

Here, n=23

Q1=\dfrac{(23+1)}{4}\ th\ term

Q1=6 th term

Q1=29

Q2=12 th term

Q2=41

Q3=18 th term

Q3=60

Hence, five-number summary for the given data is:

Min  Q1   Q2   Q3   Max

16     29   41     60    84

Where is the hole for the following function located?
Drupady [299]

<em>At x = -3 is located a hole. </em>

<h2>Explanation:</h2>

In this problem, we have the following function:

f(x)=\frac{x+3}{(x-4)(x+3)}

A hole will lie at the x-values that makes the function undefined, that is, when the denominator is zero. In a mathematical language:

(x-4)(x+3)=0

From this equation, we get two solutions:

x=4 \\ \\ x=-3

At those x-values the function will have a hole. From the choices:

<em>At x = -3 is located a hole. </em>
