andrey2020 [161]

Answer:

(a/b)^k=a^k/b^k

Step-by-step explanation:

Using the laws of exponents, we know that (a/b)^k=a^k/b^k.

I couldn't get it to format correctly so just know that the "/" are for the fraction signs and the "^" is for the exponent marking.

(05.01) A scale drawing of a bedroom is shown below. the scale is 1:30
vlabodo [156]

Answer:

ok so we know that the real bed room is 30 times bigger so we just have to multiply by 30

4*30=120

3*30=90

then we just have to multiply these together to get the square feet so

120*90=10800

so the answer is... 10800ft^2

Hope This Helps!!!

C(8,-1) and D (-2,3) what is the distance between the two points
Alex Ar [27]

Answer:

D=10.71

Step-by-step explanation:

Here we are given with two coordinates and asked to determine the distance between them.

Here we are going to use the distance formula, which is given as under

D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

Where

(x_1,y_1) = (8,-1)

(x_2,y_2) = (-2,3)

Replacing these values in the distance formula

D =\sqrt{(3-(-1))^2+(-2-8)^2}

D =\sqrt{(3+1))^2+(-10)^2}

D =\sqrt{(4)^2+(-10)^2}

D =\sqrt{16+100}

D =\sqrt{116}

D= 10.71
