A) as the exponent decreases by one, the number is divided by 5

B) as the exponent decreases by one, the number is divided by 4

C) as the exponent decreases by one, the number is divided by 3

D) 4⁰ = 4 ÷ 4 = 1

    4⁻¹ = 1 ÷ 4 = \frac{1}{4}

    4⁻² = \frac{1}{4} ÷ 4 = \frac{1}{16}

E) 3⁰ = 3 ÷ 3 = 1

    3⁻¹ = 1 ÷ 3 = \frac{1}{3}

    3⁻² = \frac{1}{3} ÷ 3 = \frac{1}{9}

Find the circumference and area of a circle with a diameter of 22 inches.
Katyanochek1 [597]

Answer:

  Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2

Step-by-step explanation:

Diameter of the circle=22\;inches

Radius=\dfrac{22}{2} =11\;inches

Circumference of a circle:

            =2\times \pi \times r

            =2\times \pi \times 11\\\\=22\pi \;inches

Area of the circle:

                  =\pi \times r^2

                 =\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2

A(x, 1), B(5,3) and C(4,-3) are the vertices of triangle ABC. If AB=AC, find the value of x​
Molodets [167]

\\ \rm\longmapsto AB=AC

\\ \rm\longmapsto \sqrt{(x-5)^2+(1-5)^2}=\sqrt{(x-4)^2+(1+3)^2}

\\ \rm\longmapsto (x-5)^2+(-2)^2=(x-4)^2+4^2

\\ \rm\longmapsto (x-5)^2+4=(x-4)^2+16

\\ \rm\longmapsto (x-5)^2-(x-4)^2=16-4=12

\\ \rm\longmapsto x^2-10x+25-x^2+8x-16=12

\\ \rm\longmapsto -2x+9=12

\\ \rm\longmapsto -2x=12-9=3

\\ \rm\longmapsto x=\dfrac{3}{-2}=-1.5
