Determine the correct set up for: log x + log (x-9) = 18
Answer:
log ( x(x-9)) = 18
Step-by-step explanation:
We know that log a + log b = log ( a* b)
log x + log (x-9) = 18
log ( x* (x-9)) = 18
log ( x(x-9)) = 18

Factor x3 x2 x 1 by grouping. What is the resulting expression?.
The factors of the equation [tex]\rm x^3+x^2+x+1\\\\[/tex] are [tex]\rm (x^2 +1)(x +1)[/tex].
What are the factors?
A factor is a number that divides another number leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.
Given
The equation is;
[tex]\rm x^3+x^2+x+1[/tex]
The factors of the equation are given by;
[tex]\rm = x^3+x^2+x+1\\\\ = x^2(x +1) + 1( x +1 )\\\\= (x^2 +1)(x +1)[/tex]
Hence, the factors of the equation [tex]\rm x^3+x^2+x+1\\\\[/tex] are [tex]\rm (x^2 +1)(x +1)[/tex].

Total shampoos=30/6=5A rectangle prism has a length of 7 cm, a width of 4 cm, and a height of 2 1/2 cm.
The prism is filled with cubes the have edge lengths of 1/2 cm .
How many cubes are needed to fill the rectangular prism?
Enter your answer in the box.
To fill the rectangular prism,_____ cubes are needed.
Answer:
The heartened are in cm so it's L x W x H which would be 7 x 4 x 2.5 = 70cm cubes.
But because our cubes are 1/2cm cubes, each 1cm cube holds 8 1/2 cm cubes. (2 x. 05 long by 2 x 0.5 wide by 2 x 0.5 high)
So we need to multiply our 70 cm cubes by 8.
70x 8 = 560 1/2 cm cubes.

Step-by-step explanation:
The hight
Answer:
Angle of depression = 51° (to nearest degree)
Step-by-step explanation:
Using tan trig ratio (where x is the angle, O is the side opposite the angle and A is the side adjacent to the angle)
[tex]tan(x)=\dfrac{O}{A}=\dfrac{9.3}{7.4}=\dfrac{93}{74}\\\\\implies x=\arctan\left(\dfrac{93}{74}\right)=51.49 \textdegree[/tex]
So angle of depression is 51.49° (to nearest hundredth)

Step-by-step explanation:
The cable company withdraws $67 per month from Denise's checking account
for automatic bill payment. There was $250.75 in Denise's checking account at
the beginning of the year, and no other deductions or additions were made to
the account. How much money is in the account after two months?
Answer: 116.75
Step-by-step explanation: Since $67 is being withdrawn from her checking account EACH month the equation would be $250.75 - 67x.
We already know the value of "x" (2) so we plug that in.
250.75 - 67(2)
Now we multiply and subtract.
250.75 - 134
116.75
The line that passes through the points (-6, p) and (-10, 2) has a slope of -1/6. What is the value of p?
Work Shown:
Slope = rise/run
Slope = (change in y)/(change in x)
Slope = (2-p)/(-10-(-6))
Slope = (2-p)/(-10+6)
Slope = (2-p)/(-4)
Set this equal to the stated slope -1/6 and solve for p
(2-p)/(-4) = -1/6
6(2-p) = -4(-1)
12-6p = 4
-6p = 4-12
-6p = -8
p = -8/(-6)
p = 4/3

Answer:
13,260.22 mm²
Step-by-step explanation:
the area of the shaded region is the area of the larger circle minus the area of the smaller one
to find the area of the larger we will use half of 62 plus 41 as the radius:
Area (larger) = 3.14(72)²
= 16,277.76
Area (smaller) = 3.14(31)²
= 3,017.54
Area (shaded region) is 16277.76 - 3017.54 = 13,260.22 mm²

James carries a balance on his credit card each month. Today is the first
day of the new, 30-day billing cycle. The current balance is $x and the APR
is 30%. James is buying his father a gift that costs $1,500 that he plans to
put on his credit card. This will be his only purchase this month, and he will
be making this purchase on the first day of the billing cycle. If his finance
charge will be $60, what is the current balance on his credit card *
James's current balance on his credit card is $900.
This amount represents the card's balance before the current charge of $1,500 and the finance charge of $60.
What is a credit card balance?A credit card balance is the amount of the charges made on a credit card, including the finance charges, and therefore, owed to a credit card company.
Data and Calculations:Current current balance = $x
APR (Annual Percentage Rate) of interest = 30%
Monthly APR = 2.5% (30%/12)
Current purchase for the month = $1,500
Finance charge for the month = $60
Finance charge for the current purchase = $37.50 ($1,500 x 2.5%)
Finance charge for the current balance = $22.50 ($60 - $37.50)
The current balance that attracts the finance charge of $22.50 will be $900 ($22.50/2.5%).
Alternatively:
Since the monthly APR is 2.5% and the finance charge is $60 for the month, the balance at the end of the month is $2,400 ($60/2.5%).
Thus, the current balance on James' credit card is $900 ($2,400 - $1,500) while the end-of-the-month balance is $2,460 ($900 + $1,500 + $60).

Yolanda has quarters, Q, and dimes, D, in her coin jar. She has a total of 31 coins.
The total amount of money in the jar is $4.75\$4.75$4.75 . Write two equations that could be used to find the number of quarters and the number of dimes in the jar.
Solve the equations to find out how many quarters and
how many dimes Yolanda has in her jar.
Answer:
11 Quarters 20 Dimes
Step-by-step explanation:
Q+D=31
25Q +10D = 475 (miltiplied all by 100 to avoid decimals)
Multiply the first by -10(to eliminate D)
-10Q - 10D = - 310
25Q+10D = 475
ADD BOTH( D will cancel)
15Q = 165
Q= 11
31-11 =20 (dimes =20)
11x0.25 = 2.75
20x0.10=2
2.75+2 = $4.75

Answer:
100 (I believe)
Step-by-step explanation:
The length would be 20
20 x 2 (because we have two sides) is 40
the width would have to be 5 then
5x2 (because we have to sides) is 10
5x4 is 20 (Showing that the length is 4 times the width)
40 + 10 = 50 (Which is the perimeter)
Since we know the length is 20 and the width is 5
we just do
20 * 5 = 100
Answer:
L = 20
Width = 5
Step-by-step explanation:
"The perimeter of the rectangle is equal to 2 times length + 2 times width:
P = 2L + 2W
We know that length is 4 times the width, so L = 4 W
We can now replace l by 4W in the equation of the perimeter:
P = 2L + 2W = 50
P = 2(4W) + 2W = 50
P = 8W + 2W = 50
P = 10W =50
So W = 50 /10
W = 5
And L = 4W
L= 4 (5)
L = 20"
2O × 5 = 100

Enter the correct answer
Answer: (x°)° * (9x-8)*1
Step-by-step explanation: With the given functions, we can simplify this easily. g(x) = x°, so then multiplying the two functions together, is easy since they are simple equations. You get (x°)° * (9x-8) * 1 (since 1 was apart of the g function equation)
Find t′(x) from t(x)=√(−3x−7) using the definition of a derivative.
By definition of the derivative,
[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{t(x+h) - t(x)}h[/tex]
[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{\sqrt{-3(x+h)-7} - \sqrt{-3x-7}}h[/tex]
Rationalize the numerator by multiplying the fraction uniformly by its conjugate:
[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{\sqrt{-3(x+h)-7} - \sqrt{-3x-7}}h \times \dfrac{\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}}{\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}}[/tex]
[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{\left(\sqrt{-3(x+h)-7}\right)^2 - \left(\sqrt{-3x-7}\right)^2}{h \left(\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}\right)}[/tex]
[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{(-3(x+h)-7) - (-3x-7)}{h \left(\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}\right)}[/tex]
[tex]\displaystyle t'(x) = \lim_{h\to0} \frac{-3h}{h \left(\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}\right)}[/tex]
[tex]\displaystyle t'(x) = -3 \lim_{h\to0} \frac1{\sqrt{-3(x+h)-7} + \sqrt{-3x - 7}}[/tex]
The remaining limand is continuous at h = 0, so we can substitute h = 0 directly and get a limit/derivative of
[tex]\displaystyle t'(x) = -\frac3{\sqrt{-3(x+0)-7} + \sqrt{-3x - 7}} = \boxed{-\frac3{2\sqrt{-3x-7}}}[/tex]
