A gum ball has a radius that is 30mm. The radius of the gumballs spherical hollow core is 28mm. What is the volume of the gum ba

Arada [10]

Answer:

V = 21145.01 mm³

Step-by-step explanation:

Given that:

The radius of the gumball = 30 mm

The radius of the spherical hollow-core = 28 mm

Consider the radius of the gumball to be $r_2$ and the radius of the spherical hollow-core to be $r_1$ . Then;

The volume of the gumball can be determined by using the formula of a sphere.

$V = \dfrac{4}{3}\pi (r_2^3 - r_1^3)$

$V = \dfrac{4}{3} \times \pi \times (30^3 - 28^3)$

V = 21145.01 mm³

Choose the point-slope form of the equation below that represents the line that passes through the points (-6, 4) and (2, 0).

Arte-miy333 [17]

Point slope form
y-y1=m(x-x1)
slope=m
a point is (x1,y1)

slope=(y2-y1)/(x2-x1)
given
(-6,4) and (2,0)
slope=(0-4)/(2-(-6))=-4/(2+6)=-4/8=-1/2

a point is (-6,4)
x1=-6
y1=4

y-4=-1/2(x+6)

Which values of a and b in the exponential function y = a times b Superscript x would result in the following graph? On a coordi

galina1969 [7]

Answer:

$a =-3$ $b =2$

Step-by-step explanation:

Given

$y = ab^x$

$(x_1,y_1) = (0,-3)$

Required

Find a and b

Substitute $(x_1,y_1) = (0,-3)$ for x and y in $y = ab^x$

$-3 = ab^0$

$-3 = a * 1$

$-3 = a$

Rewrite as:

$a =-3$

The above implies that (a) is correct;

Hence:

$a =-3$ $b =2$

So, the equation is:

$y = -3(2)^x$
