Answer:

True

Answer:

True.

Step-by-step explanation:

The slope-intercept form is: y = mx + b

<em>m</em> = slope (or 2 in this case)

<em>b</em> = y-intercept (or -8 in this case)

y & x comes from the coordinates (y, x).

Find the volume of a cone with radius 4 inches and height 5 inches. Round your answer to two decimal places
faltersainse [42]

Answer:

Volume of the cone = 83.73 cubic inches

Step-by-step explanation:

Given:

          Radius of the cone= 4 inches

           Height of the cone= 5 inches

Volume of a cone(V) :  

                                     \pi *r^2*\frac{h}{3}

Putting the given values in the formula:

               Volume of the cone:

                                3.14*4*4*\frac{5 }{3}                                           :\pi =\frac{22}{7} =3.14

                                 16*3.14*\frac{5}{3}

                                 83.73  cubic inches

So, the volume of the cone up to two decimal places is 83.73  cubic inches

Find (2.2 x 107)(5 x 108) (2.5 x 103)(8.8 x 105) expressed in scientific notation.
jarptica [38.1K]

Answer:

Scientific notation of the multiplication is 2.42\times 10^{25}

Step-by-step explanation:

(2.2\times 10^{7})(5\times 10^{8})(2.5\times 10^{3})(8.8\times 10^{5} )

= (2.2\times 5\times 2.5\times 8.8)10^{(7+8+3+5)}

[Since 10^{a}\times 10^{b}=10^{(a+b)}]

= 242\times 10^{23}

= 2.42\times 10^{25}

Therefore, the scientific notation of the multiplication is 2.42\times 10^{25}
