Answer:
Option (3)
Step-by-step explanation:
Given expression represents the sum of k terms of a geometric sequence.
[tex]\sum_{k=1}^{9}2(4)^{k-1}[/tex]
Since, formula to calculate the sum of a geometric sequence is given by,
[tex]\sum_{n=1}^{n}a(r)^{n-1}=\frac{a(1-r^n)}{1-r}[/tex]
By this formula,sum of 9 terms of the given sequence will be,
[tex]\sum_{k=1}^{9}2(4)^{k-1}=\frac{2(1-4^9)}{1-4}[/tex]
Therefore, Option (3) will be the answer.

What is the volume of the figure? Enter the answer in the box.
cubic centimeters
Answers
Answer:
35cm
Step-by-step explanation:
The volume of the figure is sum of the two individual cuboids which is
164 cm³.
What is a cuboid?A cuboid is a three-dimensional closed figure which has volume along with surface area.
The volume of a cuboid is the product of its length, width, and height.
The total surface area of a cuboid is 2(lw + wh + wl) and the lateral surface area is 2(l + w)×h.
The total volume of the given figure would be the sum of the two cuboids
which is,
= (5×5×8) + (8×8×1) cm³.
= 200 + 64 cm³.
= 264 cm³.
So, The volume of the figure is 264 cm³.

What is base and power?Raising a base number to an exponent is referred to as "power" in mathematics. It indicates that "base number" and "exponent" are the two fundamental components of powers. The exponent shows how many times the base number has been multiplied, whereas the base number is defined as a number that is multiplied by itself.
In a nutshell, power is a number that has exponents used to express it. It means that the same element has been multiplied repeatedly. In the context of powers, the following specific terminology may be used:
Whenever a number:
Squared = power is 2
cubed = Power is 3
to the power of n = used for powers more than 3
The data given gives as an equation as followed
⇒ [tex]4^{2x}[/tex] ÷ [tex]8^x[/tex] = 32
⇒ [tex](2^2)^{2x}[/tex] ÷ [tex](2^3)^{x}[/tex] = 32
⇒ [tex]2^{4x}[/tex] ÷ [tex]2^{3x}[/tex] = 32
⇒ [tex]2^{(4x - 3x )}[/tex] = 32 (If the base is same in a division, then the powers

12 ounce costs $4.11
$1.79 ÷ 4 = 0.4475 per ounce
