If f(x) = (1/8)(8^x), what is f(3)?
Answer:
f(3)=64
Step-by-step explanation:
f(3)=(1/8)(8 cubed)
f(3)= 8 to the negative one times 8 cubed
f(3)= 8 squared
f(3)=64
Answer:
f(3) = 64
Step-by-step explanation:
In this question, you would plug in "3" to "x" and solve.
Solve:
f(3) = (1/8)(8³)
f(3) = (1/8)(8·8·8)
f(3) = (1/8)(512)
f(3) = 512/8
Simplify.
f(3) = 64
Your final answer would be f(3) = 64

The ratio of Mollie’s age to Heather’s age is 4:9 Heather is 40 years older than Mollie
How old is Mollie?
Answer:
I believe it would be 90
Step-by-step explanation:
The required age of Mollie's is 32years and age of Heather's is 72years.
Given that,
The ratio of Mollie’s age to Heather’s age is 4:9,
Heather is 40 years older than Mollie.
We have to determine,
How old is Mollie.
According to the question,
The ratio of Mollie’s age to Heather’s age is 4:9,
The age of Mollie's = 4x
And age of Heather's = 9x
Then ,
The age of Mollie is calculated in the following steps.
The difference between the age of both is 40 years
Age of Heather's - Age of Mollie = Difference of their ages
Then,
[tex]= 9x-4x = 40\\\\= 5x = 40\\\\= x = \frac{40}{5} \\\\= x = 8[/tex]
The value of x is 8.
Therefore,
Age of Mollie's = 4x = (4).(8) = 32years
And Age of Heather's = 9x = (9).(8) = 72years
Hence, The required age of Mollie's is 32years and age of Heather's is 72years.

Tyler orders a meal that costs $15. The sales tax rate in Tyler's county is 6.6%. Write an equation to represent the relationship between the original cost of the meal and the cost after the sales tax. Use x for the original cost for the meal and y for the cost after sales tax.
Answer:
Step-by-step explanation:
y = (1.066)x
The equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x
How to calculate the sales tax?The sales tax is the amount charged on the price of goods and services.
Let x be the original cost for the meal
Let y be the cost after the sales
If the sales tax rate in Tyler's county is 6.6%, the tax charged is expressed as:
0.066 of theoriginal cost
0.066x
Cost after tax = original cost + tax
Cost after tax = x + 0.066x
y = 1.066x
Hence the equation to represent the relationship between the original cost of the meal and the cost after the sales tax is y = 1.066x

After 24h will be 108p
Each c is 6m
12 laps
Step-by-step explanation:
36 - 33 = 3
33 - 30 = 3
30 - 27 = 3
27 - 3 = 24
12h = 36p
12h × 3 = 36h
So 36p need to × 3 too
36p × 3 108p
Because 3c to 5c, 18m to 30m need 12m. There was no 4c so the 12m need to divide two. 12m ÷ 2 = 6m.
So each c is 6.
72 ÷ 6 = 12

Step-by-step explanation:
:P
Answer:
15/20(3/4), 9/10
Step-by-step explanation:
well in order to add or subtract fractions for that matter, you must have the a common denominator meaning the bottom number on both of the fractions must be the same. and in order to do that you must take the smaller denominator and find what can multiply that into the bigger denominator so in your case 5 is the smaller denominator so in order to get 20 we multiply by 4 and so what you do to the bottom you must also do to the top so we have 3 and now we must also multiply that by 4 leaving us with 12/20 as our new fraction. so now the adding is easy, 7+12=15 and you keep the same denominator 20
so your first answer would be 15/20 and if you need that simplified then you do the same thing once again and you find a common factor between your denominator (the bottom number) and the numerator (the top number) and in this case they do have a common factor which is 5 therefore if you divide both parts ofthe fraction by 5 it will leave you with 3/4 which is your simplified answer to this first question
now for the second equation i'm not going to go through the steps one by one again, as we already have but you may feel free to practice these on your own, but if we skip the step of creating the denominators to be the same with a common factor, then we will should have 6/10+3/10 leaving us with 9/10 as our simplified answer because 9 and 10 do not have any number in common to divide by.

Consider the following portion of an electric circuit with three relays. Current will flow from point a to point b if there is at least one closed path when the relays are activated. The relays may malfunction and not close when activated. Suppose that the relays act independently of one another and close properly when activated, with a probability of .9. Given that current flowed when the relays were activated, what is the probability that relay 1 functioned?
Answer:
0.9009
Step-by-step explanation:
Let X be the event that Current will flow
Let Y be the event that the first relay which is 1 is closed
Thus, we can say that every element of Y is in X, but X possesses more elements. Thus, Y ⊂ X.
Thus, we can say that;
P(X ∩ Y) = P(Y)
Thus, given that current flowed, the probability that relay 1 functioned will be expressed as;
P(Y | X) = (P(Y ∩ X))/P(X)
From earlier, we saw that P(X ∩ Y) = P(Y). Thus;
P(Y | X) = P(Y)/P(X)
From the question, P(Y) = 0.9
Since there are 3 relays, then we have;
P(X) = 1 - 0.1³ = 0.999
Thus;
P(Y | X) = 0.9/0.999
P(Y | X) = 0.9009
The probability that relay 1 functioned is 0.9009
Calculation:
Let us assume X be the event that Current will flow
And,
Let us assume Y be the event that the first relay
So, Thus, Y ⊂ X.
Now
P(X ∩ Y) = P(Y)
The probability that relay 1 functioned should be
P(Y | X) = (P(Y ∩ X)) ÷ P(X)
From earlier, we saw that P(X ∩ Y) = P(Y).
So,
P(Y | X) = P(Y) ÷ P(X)
Now
P(X) =[tex]1 - 0.1^3[/tex] = 0.999
So,
P(Y | X) = 0.9 ÷0.999
P(Y | X) = 0.9009

The curve y=ax2+bx+c passes through (2,5) (3,12) and (-1,-4).find the equation of the curve
Explanation:
You want to first to substitute to form 3 equations.
5=4a+2b+c
12=9a+3b+c
-4=a-b+c
Now solve with whatever way you fell comfortable, I'm going to use elimination.
First eliminate c
7=5a+b
16=8a+4b --> 4=2a+b
Then I'll eliminate b,
3=3a
a=1
Now solve for b and c
7=5+b
b=2
1-2+c=-4
c=-3
Now for the equation:
y=x^2+2b-3

Use slope-intercept form to write an equation of a line passing through the given point and having the given slope. Express the answer in standard form. P(-4,-9); m= -3/4
Answer:
4y = -3x - 48
Step-by-step explanation:
y - y1 = m(x - x1)
y1 = -9 x1= -4 m = -3/4
y -(-9) = -3/4(x -(-4)
y + 9 = -3/4(x + 4)
y + 9 = -3/4x -12/4
multiply through by 4
4y + 36 = -3x -12
4y = -3x -12-36
4y = -3x -48 in the form y = mx + c

Answer:
[tex] y = 4 [/tex]
Step-by-step explanation:
Given:
[tex] y = \frac{7x + 1}{3x - 6} [/tex],
To find the value of y, let's find x by solving 3x = 15.
3x = 15
Divide both sides by 3
x = 15/3
x = 5
Plug in the value of x into [tex] y = \frac{7x + 1}{3x - 6} [/tex]
[tex] y = \frac{7(5) + 1}{3(5) - 6} [/tex]
[tex] y = \frac{35 + 1}{15 - 6} [/tex]
