Answer:
x=5
Step-by-step explanation:
First, let's understand logarithms.
When there is no base given, like in this problem's right side of the equation, the base is automatically 10.
So, let's re-write that.
[tex]\frac{7}{x+2}=log_{10}x+5[/tex]
Now, let's test a few of the numbers out. For brevity, I already know it's 3. Let's show you why.
[tex]\frac{7}{5+2} =log_{10}(5+5)\\\frac{7}{7} = log_{10}(10)\\1 = 1[/tex]

Given f(x) = x + 1 and g(x) = x^2, what is (g o f) (x)?
A. (g o f) (x) = x^2+x+1
B. (g o f) (x) = x^2+1
C. (g o f) (x) = (x + 1)^2
D. (g o f) (x) = x^2(x + 1)
Answer:(g o f)(x)=x^2+x+1
Step-by-step explanation:
It is Given f(x) = x + 1 and g(x) = x^2 therefore, the function (g o f) (x) is x^2 + x + 1.
What is function of functions and how are they represented?The function of function, as the name suggests, is functions applied over functions themselves. This is also called function composition.
We have input. We apply one function on that input. Then we apply another function on the output obtained by the first function. This whole function application on the first input is called the function of functions.
The resultant function which maps the input x to the final output is called the function of a function.
If the first function is g( and the other function is f, then we can write the resultant function of the function as
[tex](f\circ g)(x)[/tex]
where the x is the input to the first function.
Thus, we have;
[tex](f\circ g)(x) = f(g(x))[/tex]
It is Given f(x) = x + 1 and g(x) = x^2, we need to find (g o f) (x)
(g o f)(x) = g(x) + f(x)
= x^2 + x + 1

use integers or simplified fractions for any number I the expression
Answer:
[tex]y = - \frac{4x}{107} + 12[/tex]
Step-by-step explanation:
You start with 12 gallons, and for every mile that you drive, you will deplete [tex]\frac{1}{321}[/tex] of your total amount of gas, or [tex]\frac{12}{321} = \frac{4}{107}[/tex] gallons of gas for every mile you drive.

Your family's new business is finally starting to get on track. You started with an investment of $20,000, but lost 10% the first year, 6% the second year, and 3$ the third year. During the fourth year, however, you gained 5%
(A) How much money did you have after the first three years?
(B) What was the cumulative decay factor after the first three years?
(C) What was the cumulative factor after the first four years? Does this factor represent decay or growth?
(D) What percent increase do you need to get during the fifth year to break even (end up with $20,000)?
Answer:
A)
$16412.40.
B)
Our culminate decay factor was 0.82062.
C)
0.861651. It represents decay because it's less than one.
D)
We need at least a 16.1% increase.
Step-by-step explanation:
We started off with $20,000. In the first year, we lost 10%. In the second year, we lost an additional 6%, and another 3% in the third year. During the fourth year, however, we regained 5%.
Part A)
In the first year, we lost 10% of our original investment. In other words, we will have left 100% - 10% or 90% of our original investment. So, after the first year, we will have:
[tex]20000(0.9)=\$ 18000[/tex]
During the second year, we lost another 6%. So, it will be 100% - 6% = 94% = 0.94 of our current investment. So, after the second year, we will have:
[tex]18000(0.94)=\$ 16920[/tex]
Finally, during the third year, we lost 3%. So, it will be 100% - 3% = 0.97 of our current investment:
[tex]16920(0.97)=\$ 16412.4[/tex]
After the first three years, our investment dwindled down to $16412.40.
Part B)
We started off with $20,000 and ended up with $16412.40. Let r represent the decay factor. We can write the following equation:
[tex]20000d=16412.4[/tex]
This reads, "our original investment of $20,000 by multiplied by some (decay) factor equals our current investment of $16412.4."
Solve for d:
[tex]\displaystyle d=\frac{16412.4}{20000}=0.82062[/tex]
So, our decay factor is 0.82062.
(Note: This means that our rate of decay was 1 - 0.82062 = 0.17938. So, we lost approximately 18% of our investment over the course of the three years.)
Part C)
After the third year, our investment was $16412.40.
During the fourth year, we gained 5% on our investment. So, it will be 100% + 5% = 105% = 1.05 of our current investment:
[tex]16412.4(1.05)=\$ 17233.02[/tex]
Again, we can write an equation:
[tex]20000d=17233.02[/tex]
Where d represents the culminative factor after four years.
Solving for d yields:
[tex]d=0.861651[/tex]
Since the culminative factor is less than one, this is decay.
Decay is also correct contextually, since after four years, our current investment is lower than our original investment.
Part D)
After the fourth year, we have $17233.02.
In order to find the percent increase to rereach $20,000, we can write an equation:
[tex]17233.02d=20000[/tex]
Solving for d yields:
[tex]\displaystyle d\approx 1.1606[/tex]
So, the growth factor is about 1.1606.
This means that during the fifth year, we will need to grow by 1 - 1.1606 or about 16.1% in order to rereach our original investment of $20,000.
Divide and simplify.

Step-by-step explanation:
cbhchchfvhvhshc;h
Answer:
456.73 cm²
Step-by-step explanation:
Area of a circle = πr²
The radius of the hub cap
= 75.74÷3.14÷2
= 12.06 cm (rounded to the nearest hundredth)
The area of the hub cap
= 3.14 × 12.06²
= 456.7314968152...
= 456.73 cm² (rounded to the nearest hundredth)
Circumference means the perimeter of a circle. So if the perimeter of a shape is smaller, it makes the shape turn out to be smaller.
So the area of the hub cap will be smaller.

A research study comparing three treatments with n= 5 in each treatment produces T1= 5, T2= 10, T3= 15, with SS1= 6, SS2= 9, SS3=9, and EX= 94. For this study, what is SSbetween
Answer:
SSbetween is 10
Step-by-step explanation:
Given the data in the question;
A research study comparing three treatments with n = 5 in each treatment produce;
that is: n₁ = 5, n₂ = 5, n₃ = 5
T₁ = 5, T₂ = 10, T₃ = 15,
SS₁ = 6, SS₂ = 9, SS₃ = 9
∑x² = 94
First, we obtain the grand total;
G = T₁ + T₂ + T₃ = 5 + 10 + 15 = 30
N = n₁ + n₂ + n₃ = 5 + 5 + 5 = 15
Total SS = ∑x² - ( G²/N )
we substitute
Total SS = 94 - ( (30)²/ 15 )
Total SS = 94 - ( 900 / 15 )
Total SS = 94 - 60
Total SS = 34
To get the SSbetween or Between SS;
Between SS = ∑( T²/n ) - ( G²/N )
Between SS = ∑( (5)²/5 + (10)²/5 + (15)²/5 ) - ( (30)²/ 15 )
Between SS = ∑( 25/5 + 100/5 + 225/5 ) - ( 900 / 15 )
Between SS = ∑( 5 + 20 + 45 ) - 60
Between SS = 70 - 60
Between SS = 10
Therefore, SSbetween is 10

A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides. Determine the smallest possible length of the hypotenuse.
Answer:
Smallest possible length of the hypotenuse = 65
Step-by-step explanation:
Given - A right angle triangle has sides whose lengths are $2$-digit integers. The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.
To find - Determine the smallest possible length of the hypotenuse.
Proof -
The possible Pythagoras triplets of a right angled triangle with 2 digit integers are -
(11, 60, 61)
(12, 35, 34)
(13, 84, 85)
(16, 63, 65)
(20, 21, 29)
(28, 45, 53)
(33, 56, 65)
( 36, 77, 85)
(39, 80, 89)
(48, 55, 73)
(65, 72, 97)
But, Here Given that
The digits of the length of the hypotenuse are the reverse of the digits of the length of one of the other sides.
So, There is only one possibility that satisfy the condition.
and that is, (33, 56, 65)
So, we get
Length of one side = 33
Length of second side = 56
Length of hypotenuse = 65
So,
Smallest possible length of the hypotenuse = 65

1 Show that (e + 5) is a factor of f (x) = - 22 - 23e + 60 then factor f (x) completely. You will need to use synthetic division for this,
Answer:
(x+5)(x-4)(x-3)
Step-by-step explanation:
Divide (e+5) into e³-2e²-23e+60 using polynomial long division (picture attached below). Since it divides in evenly, we can see it is a factor.
So we can say e³-2e²-23e+60 = (e+5)(e²-7e+12)
To complete the factorisation, factorise e²-7e+12.
Note that (x+a)(x+b)=x²+(a+b)x+ab. So find the multiples or 12 which can be added or subtracted to get -7: -4 and -3.
e²-7e+12=(x-4)(x-3)
So e³-2e²-23e+60 = (x+5)(x-4)(x-3)
