To solve this problem you simple have to think which of the following option would carry your shape into itself. Or in simpler words which one would make it go 360 degrees around. The correct set of reflections and rotations would be:

<span>Reflect over the y-axis, reflect over the x-axis, rotate 180°.

I hope it helps, Regards.</span>

Evaluate the expression for x = 2 and y = 4. Enter your answer in the box.<br><br> 16x0 + 2x2 • y –1

swat32

Given that,

The given expression is : $16x^0+2x^2{\cdot}y^{-1}$

To find,

The value of the above expression when x = 2 and y = 4

Solution,

We have,

$16x^0+2x^2{\cdot}y^{-1}$

Put x = 2 and y = 4 in the above expression.

$16x^0+2x^2{\cdot}y^{-1}\\\\=16\times (2)^0+2(2)^2\times (4)^{-1}\\\\=16\times 1+2(2)^2\times\dfrac{1}{4}\\\\=16+2\\\\=18$

So, the value of the above expression is 18.

Tara and Jody's bedrooms are shaped like rectangles. Tara's bedroom is 9 ft long and 8 ft wide. Jody's bedroom is 7ft long and 1

horrorfan [7]

Tara's Bedroom: A = lw
A = (9)(8)
A = 72 ft²

Jody's Bedroom: A = lw
A = (7)(10)
A = 70 ft²

Tara's bedroom has the greater area than Jody's bedroom.

What is the radius of the circle ? (X-3^2+(y-4)^2=49

vodomira [7]

Answer:

7 units

Step-by-step explanation:

The formula for a circle is: $(x-x_1)^2+(y-y_1)^2=r^2$ , where (x_1, y_1) is the center of the circle and r is the radius.

Right now, we see that r^2 = 49, so to find r, we square root 49 and get 7.

Thus, the answer is 7 units.

Hope this helps!

2(vh)/k=r Solve equation for v in terms of all other variables involved

aivan3 [116]

The equation v in terms of other variables is v = kr/2h

<h3>What is the subject of an equation?</h3>

It is a variable which is expressed in terms of other variables involved in the formula.

Formulas are written so that a single variable, the subject of the formula is on the L.H.S. of the equation. Everything else goes on the right side of the equation. We evaluate the formula by substituting for the literal numbers on the right hand side.

2(vh) / k = r

by cross multiplication

2(vh) = kr

divide both sides by 2h

v = kr/2h

In conclusion, v in terms of other variables is kr/2h
