The two spheres above have the same center. One has a radius of 4 cm, and the other has a radius of 5 cm. Approximately how much
Zanzabum
The space between the two spheres will be the volume of the larger sphere minus the volume of the smaller sphere.  Given that the volume of any sphere is:

V=(4πr^3)/3  The space between to sphere of different radius and positioned about the same center is:

S=(4πR^3)/3-(4πr^3)/3  I used S=volume of space, R=larger radius and r=smaller radius...

S=(4π/3)(R^3-r^3), we are told that R=5 and r=4 so

S=(4π/3)(5^3-4^3)

S=(4π/3)(125-64)

S=(4π/3)(61)

S=244π/61

S=4π cm^3

S≈12.57 cm^3  (to nearest hundredth of a ml)

What is the base area.
Mariulka [41]

Answer:

Area of the base is 10.5 cm².

Step-by-step explanation:

Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases

Vertical height = 6 cm

Volume = 63 cm³

From the formula,

63 = Area of the triangular base × 6

Area of the base = \frac{63}{6}

                            = 10.5 cm²

Therefore, area of the base is 10.5 cm².

the function below represents the number of zombies, N, where t is the number of years since the zombies gained control of earth
raketka [301]
There is missing information about this question that I found online.
Given function is:
N(t) = 300\cdot 2^{-\frac{t}{8}}
The question is:
<span>Is this exponential growth or decay? Explain using your understanding of the properties of exponents.
</span>This is an exponential decay. 
In general, we can write down exponential functions like this:
f(x)=b^{ax}
Parameter a is the key parameter that will tell how exponential function behaves. If it is positive we have an exponential growth. If it is negative we can rewrite function like this:
f(x)=b^{-ax}=\frac{1}{b^{ax}}
We can notice that in this case, the denominator will exhibit exponential growth, in other words, the functions rapidly declines. This is an exponential decay.

The ordered pair (8,5) represents a point on the graph of a proportional relationship. Which ordered pair also represents a poin
makkiz [27]

Given the ordered pair:

(8, 5)

Let's find the ordered pair that represents a point on the same graph assuming this is a graph of a proportional relationship.

Here, we have:

(x, y) ==> (8, 5)

Since this is a graph of a proportional relationship, let's find the constant of proportionality.

We have:

K=\frac{y}{x}=\frac{5}{8}

This means when x is 1, y is 5/8.

Thus, the ordered pair that also represents a point on the same graph is:

(1,\frac{5}{8})

ANSWER:

\text{ B. (1, }\frac{5}{8})
