<span>In order to reflect a graph about the origin, the rule of translation for each point is (a,b) reflects to (-a,-b).</span><span>The reflection of the point (a,b) across the line y = x is (b,a).</span>By following these rules, you can reflect any line or figure across any of the three most common lines of reflection or the origin.<span>

A construction worker drops a hammer from a height of 25 m.

Snezhnost [94]

Answer:

Time at which the hammer reaches the ground is 2.3 seconds.

Step-by-step explanation:

We are given the formula as, $h(t)=-4.9t^2+v_{o}+h_{o}$ .

It is known that, when height i.e. $h_{o}=25$ meter, then velocity $v_{o}=0$ m/sec.

So, we get the formula as, $h(t)=-4.9t^2+25$ .

Now, when the hammer hits the ground, the height $h_{o}=0$ meter.

Thus, we have,

$h(t)=-4.9t^2+25$

⇒ $0=-4.9t^2+25$

⇒ $4.9t^2=25$

⇒ $t^2=5.1$

i.e. t= ±2.3 sec

Since, time cannot be negative.

So, t= 2.3 sec

Hence, the time at which the hammer reaches the ground is 2.3 seconds.

one more than seven times the difference of a number and 4 is equivalent to twice the difference of the number and 1

slava [35]

Answer:

the number is 5

Step-by-step explanation:

We have to find the equation to solve the problem.

Let the number be x

lets write one more than seven times the difference of a number and 4 in mathematical form

1. Difference of number and 4 will be written as x - 4

now

2. seven times the difference of a number and 4 will be written as

7*( x - 4)

3. one more than seven times the difference of a number and 4 is expressed as

1 + 7*( x - 4)

_____________________________________________

1 + 7*( x - 4) is equal to twice the difference of the number and 1

4. difference of the number and 1 is x - 1

5. twice the difference of the number and 1 is 2*(x-1)

Thus,

1 + 7*( x - 4) = 2*(x-1)

=> 1 + 7x - 28 = 2x -2

=> 7x - 27 = 2x - 2

adding 27 both sides

=> 7x - 27 + 27 = 2x - 2 + 27

=> 7x = 2x + 25

subtracting 2x from both sides

7x -2x = 2x + 25 - 2x

=> 5x = 25

dividing both side by 5

5x/5 = 25/5

x = 5

Thus, the number is 5 answer
