The formula y = 64h gives the velocity v in feet per second of an object that has fallen h feet. Find thevelocity of an object that has fallen 92 feet. Round to the nearest hundredth.

Answers

Answer:

The velocity of the object is 76.73 ft/sec

Step-by-step explanation:

* Lets explain how to solve the problem

- The formula y = √(64h) gives the velocity y in feet per second of an

object that has fallen h feet

- To find the velocity of an object that has fallen 92 feet substitute h

by 92 in the formula

∵ y = √(64h)

∵ h = 92 feet

∴ y = √64(92) = √5888 ≅ 76.73 feet/seconds

* The velocity of the object is 76.73 ft/sec

How do you do that plz help or just give the answer

2x-(-1/2x-1/2)=8
the - sign before the first parentheses is a negative 1
you distribute the -1 into the parentheses
-1 multiplied by -1/2x is 1/2x and -1 multiplied by -1/2 is 1/2.
so now we have 2x-1/2x+1/2=8
you combine like terms (2x and -1/2x)
you get 1 1/2x+1/2=8
you subtract the 1/2 to get 1 1/2x= 7 1/2
you divide everything by 1 1/2.
the answer is x=5

Help meh PleAse Which function has the greatest rate of change?

A. 14x – 2y = 8

B. y = 6x – 5

C.
x y
−2 −7
−1 −2
0 3
D.
The Graph is Letter D.

Answers

Rate of Change is the same as Slope.

A.

$\sf14x-2y=8$

Convert to slope-intercept form.

Subtract 14x to both sides:

$\sf-2y=-14x+8$

Divide -2 to both sides:

$\sf~y=7x-4$

So the rate of change here is 7.

B.

$\sf~y=6x-5$

This is already in slope-intercept form, so the rate of change here is 6.

C.

Take any two points on the graph and plug them into the slope formula.

Let's take (-1, -2) and (0, 3).
x1 y1 x2 y2

$\sf~m=(y_2-y_1)/(x_2-x_1)$

Plug in the numbers:

$\sf~m=(3-(-2))/(0-(-1))$

Subtract:

$\sf~m=(5)/(1)$

Divide:

$\sf~m=5$

So the rate of change here is 5.

D.

Take any two points on the line and plug them into the slope formula.

Let's take (0, -2) and (1, 3)
x1 y1 x2 y2

$\sf~m=(y_2-y_1)/(x_2-x_1)$

Plug in the numbers:

$\sf~m=(3-(-2))/(1-0)$

Subtract:

$\sf~m=(5)/(1)$

Divide:

$\sf~m=5$

So the rate of change here is 5.

Therefore, A has the greatest rate of change.

The table represents a linear equation. Which equation correctly uses point (–2, –6) to write the equation of this line in point-slope form? y – 6 = (x – 2) y – 6 = (x – 2) y + 6 = (x + 2) y + 6 = (x + 2)

Answers

Answer:

$y+6=m(x+2)$

where I would have to look at the table to know $m$ .

Step-by-step explanation:

Point-slope form of a line is

$y-y_1=m(x-x_1)$

where $m \text{ is the slope and } (x_1,y_1) \text{ is a point on that line}$

You are given $(x_1,y_1)=(-2,-6) \text{, but no value for }m$ .

So we know we are looking for an equation that looks like this:

$y-(-6)=m(x-(-2))$

If you simplify this looks like:

$y+6=m(x+2)$

What number goes into 51 and 9 evenly

Answers

The number that goes into 51 and 9 evenly is 3.

To find a number that goes into 51 and 9 evenly, we need to identify a common factor of both numbers. In this case, the number that evenly divides both 51 and 9 is 3.

When we divide 51 by 3, we get 17 with no remainder:

51 ÷ 3 = 17

Similarly, when we divide 9 by 3, we also get no remainder:

9 ÷ 3 = 3

Therefore, 3 is the number that goes into both 51 and 9 evenly.
