Answer:

Perimeter = 32 meters

Step-by-step explanation:

1 meter = 1m = 100 cm = 100 centimeters

400cm = 400/100 = 4 meters

Rectangle Perimeter = 2(legth + width)

= 2(12 + 4)

= 2*16

= 32 meters

The area of circle B is 121 times greater than the area of circle A. The radius of circle B is 44. What is the radius of circle

xxMikexx [17]

Formula:
$\bigg( \dfrac{radius_1}{radius_2} \bigg)^2 = \dfrac{area_1}{area_2}$

Plug in the values:
$\bigg( \dfrac{r}{44} \bigg)^2 = \dfrac{1}{121}$

Simplify LHS:
$\dfrac{r^2}{1936} = \dfrac{1}{121}$

Multiply by 1936 on both sides:
$r^2 = \dfrac{1936}{121}
$

Simplify RHS:
$r^2 = 16$

Square root both sides:
$r = 4$

Answer: The radius is 4 units. (Answer B)

Help me do examples for a function and a non function

bekas [8.4K]

Answer:

{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}

Step-by-step explanation:

you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)

an example of a function would be {(1,2) (3,4) (5,6)}

an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.

using this, another example of a function would be {(1,2) (3,2) (5,2)}

an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

If j=h and k=m then which expression represents the value of g

Colt1911 [192]

Answer:

Step-by-step explanation:

as given j=h and k=m then which expression for g is

as from attached image , we can see that its look like two right angle triangle

so from lower triangle we apply the pythagorean theorem .

which state that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

so small triangle ΔEBD

h² +k²= g² ---------------(1)

now from big triangle ΔABC

(j + h)² +(m + h)² =f²---------(2)

given j=h and k=m so from equation-2 we can find ,

(h + h)² +(k+ k)² =f²

(2h)² +(2k)²=f²

4h²+ 4k²= f²

4(h²+k²)= f² ----------(3)

now from equation 1 and 3 we can obtained .

4×g² =f²

take square root both side we get,

2×g=f

so g=f/2----- Answer

If you are asked to rotate 270° counterclockwise that's the same as rotating what other angle of rotation and direction?

mr Goodwill [35]

Answer:

90° clockwise

Step-by-step explanation:

90 degrees clockwise

when you rotate counterclockwise 270 degrees, (x,y) maps to (y,-x)

Hope this helps :-)
