A f(x) = x8
B f(x) = 8*
C f(x) = 64(2)*
D f(x) = 8x
Answer:
B. f(x) = 8*
Step-by-step explanation:
putting the value given in table
=> 512 = 8³
=> 512 = 512
=> 5,096 = 8⁴
=> 5,096 = 5,096
=> 32,768 = 8⁵
=> 32,768 = 32,768
so, it's B f(x) = 8*
Answer:
The answer is B) f(x)=8^x

An architect notices that the scale on a blueprint he is using has been torn off. However, he sees that a 21.6-foot wall that has been built is 6 inches long on the blueprint. What is the scale for this blueprint?
A. 1 in. : 3.6 ft.
B. 1 in. : 6.3 ft.
C. 1 in. : 36 ft.
D. 1 in. : 63 ft.
Answer:
The answer is - A. 1 in. : 3.6 ft.
Step-by-step explanation:
In order to get the scale on the blueprint we just have to divide the measure in real time by the number of the blueprint, if we know that there´s a wall that is 21.6 feet long, and in the blue print is 6 inches long we just divide it:
scale: 21.6/6
scale: 3.6
So, now we know that for every inch in the blueprint there has to be 3.6 feet on the real construction.

what is the difference in the length between the longest meter in the shortest meter
Answer:
1 5/8 inches
Step-by-step explanation:
Hey there!
The question is asking what the difference in the length between the longest meteor and the shortest meteor is.
In the chart, the smallest measurment is 2/8 and the largest is 1 7/8
So in order to solve this you need to subtract these two values
we can convert 1 7/8 to 15/8 to make the subtraction more simple
15/8-2/8=13/8 which is 1 5/8
So the difference between the longest and shortest meteor is 1 5/8 inch
Answer: 1 5/8.
Step-by-step explanation: The longest one is 1 7/8 and the shortest one is 2/8. Both are circled below. To figure this problem out, we need to find the difference of the longest and shortest meteors, also known as a subtraction problem. The work is done below:
1 7/8 - 2/8 = 1 5/8.
Hope this helps! :)
The flight of a javelin released six. 5 feet from the ground at an initial velocity of 68 ft./s is modeled by the function age equals 16 t^2+68t+6.5 where H is the height of the Javelin in feet after t seconds. When will the javelin hit the ground? Round to the nearest hundredth if necessary
The equation of the javelin path h(t) = -16t^2+68t+6.5 is a quadratic function
The javelin hits the ground after 4.344 seconds
How to determine when the javelin hits the ground?The equation of the javelin path is given as:
h(t) = -16t^2+68t+6.5
When it hits the ground, h(t) = 0.
So, we have:
-16t^2+68t+6.5 = 0
Using a graphing calculator, we have:
t = 4.344 and t = -0.094
Time cannot be negative.
So, we have:
t = 4.344
Hence, the javelin hits the ground after 4.344 seconds

Find the volume of the sphere. Round your answer to the nearest tenth.
Use 3.14 for a.
A sphere has a radius of 3.5 feet.
The volume of the sphere is about
ft?
Answer:
179.50
Step-by-step explanation:
The formula for calculating pi is as followed: 4/3·π·r³
The question is either asking to calculate using 3.14 for π or add π at the end of your answer instead of completing it. I will substitute π for 3.14.
∴V=4/3·3.14·3.5³
V=179.503333333
Round your answer to the nearest hundredth:
179.503333333 rounded to the nearest hundredth becomes 179.50
∴V=179.50
-------------------------------------------------------------------------------------------------------------
Another way to answer this question is to use the same formula; but not substitute 3.14 into the answer.
V=π.4/3·r³
V=π·57.1666666667
Round 57.1666666667: 57.17
V=57.17π
Either one would work. Hope this works.
The length of a rectangle is 4/5 of the width. The length of the rectangle is 3/5 meter. Which equation can be used to find w, the width of the rectangle in meters?
A 3/5w = 4/5
B 4/5w = 3/5
C 3/5 + w = 4/5
D 4/5 + w = 3/5
Answer:
B: 4/5w = 3/5
Step-by-step explanation:
The length of the rectangle is stated as being 4/5 of the w. (4/5 * w)
The length is also stated specifically as being 3/5m so that will equal 4/5w on the other side of the equation.
Bonus:
You could work out the equation as
4/5w = 3/5m
multiply by 5
4w = 3m
divide by 4
w = 0.75m (or 3/4m)

A department store buys 300 shirts at a cost of $8,100 and sells them at a selling price of $30 each. Find the percent markup.
Answer:
11.11%
Step-by-step explanation:
C.P = $8,100
S.P =$30 ×300
=$9,000
Markup = $9000-$8100
=$900
% markup = 900/8100 × 100
=11.11%
A son is one half as old as his father. The some other ages is 72 years. What is the age of each?
Answer:
The son is 24 and the father is 48
Step-by-step explanation:
If you let x = the age of the child, then the father is 2x old since the father is twice as old as the son. The sum of their ages would be 1x + 2x which simplifies to 3x.
Since the problem gives the total of their ages as 72, we know that 3x = 72.
Dividing both sides by 3, we get x = 24, which we said was the age of the child.
Since the age of the father is 2x, we can say that 2x = 2(24), or 2x = 48 for the age of the father.

Step-by-step explanation:
a geometric sequence means that every term is created by multiplying the previous term by a certain constant factor. this factor is called the "common ratio".
so,
6×r = 18
r = 18/6 = 3
and a quick check tells us this works also for the next terms (18×3 = 54, 54×3 = 162), so it is indeed a geometric sequence with common ratio 3.
a0 = 6
a1 = a0 × 3 = 6×3 = 18
a2 = a1 × 3 = a0 × 3×3 = 6×3² = 54
an = a0 × 3^n = 6 × 3^n
so,
f(x) = 6×3^x, x is integer, x >=0
