3 0

Enlargement: Anything higher than 2
Example: (2,2)
scale factor:4
Multiply coordinate by 4
New coordinate: (8,8)
Reduction: Anything less than 1
Example: (4,4)
Scale factor: 1/2
Divide coordinate by 1/2
New coordinate: (2,2)

Answer:It would be cut in half

Step-by-step explanation:The momentum of the ball is what speeds it up, like the engine to the car. It needs it to run, so if you cut it in half the speeds are cut in half.

A jar containing only nickels and dimes contains a total of 60 coins. The value of all the coins in the jar is $4.45. Solve by e

borishaifa [10]

Answer: 31 nickels and 29 dimes

Step-by-step explanation:

Nickels (.05): x

Dimes (.10): y

Value: .05x + .10y = 4.45 → -20(.05x + .10y = 4.45) → -x - 2y = -89

Quantity: x + y = 60 → 1(x + y = 60) → x + y = 60

-y = -29

y = 29

Next, substitute "29" for "y" into either equation and solve for "x":

x + y = 60

x + 29 = 60

x = 31

Which of the following statements correctlydescribes the points

gregori [183]

The first statement is correct

To calculate the distance we have to substrate the values of the Y axis only since X values are constant so the distance IS 4 - - 7=4+7=11

In a missile-testing program, one random variable of interest is the distance between the point at which the missile lands and t

Arisa [49]

Answer:

Step-by-step explanation:

From the given data

we observed that the missile testing program

Y1 and Y2 are variable, they are also independent

We are aware that

$(Y_1)^2 and (Y_2)^2$ have $x^2$ distribution with 1 degree of freedom

and $V=(Y_1^2)+(Y_2)^2$ has x^2 with 2 degree of freedom

$F_v(v)=\frac{e^{-\frac{v}{2}}}2$

Since we have to find the density formula

$U=\sqrt{V}$

We use method of transformation

$h(V)=\sqrt{U}\\\\=U$

There inverse function is $h^-^1(U)=U^2$

We derivate the fuction above with respect to u

$\frac{d}{du} (h^-^1(u))=\frac{d}{du} (u^2)\\\\=2u^2^-^1\\\\=2u$

Therefore,

$F_v(u)=F_v(h-^1)(u)\frac{dh^-^1}{du} \\\\=\frac{e^-\frac{u^-^}{2} }{2} (2u)\\\\=e^-{\frac{u^2}{2} }U$

100 POINTS!!!! Create a table of values for a linear function. A drone is in the distance, flying upward in a straight line. It

dangina [55]

Based on the docx you showed me, the equation for the parabola is $y = x^2 + 36$ and you want a table of values for a linear equation that intersects the parabola at (5, 6) and (-2, 34).

If you use these two points to create a line we get the equation:

$y - 6 = \frac{34 - 6}{-2 - 5}(x - 5)$ (I just used point slope form)

This can be simplified to:

$y = \frac{40}{-7}x + \frac{242}{7}$

Now we just need to create a table of points on this line. We already have the points you gave and we can also use the y-intercept: $(0, \frac{242}{7})$ and the x-intercept: $(\frac{121}{20}, 0)$ .

So our table of value can be:

x | y
______|________
-2 | 34
0 | 242 / 7
5 | 6
121/20 | 0
