Given:
The expression is
[tex]2\log c+3\log k[/tex]
To find:
The value after condense the logarithm.
Solution:
We have,
[tex]2\log c+3\log k[/tex]
Using properties of logarithm, we get
[tex]=\log c^2+\log k^3[/tex] [tex][\because \log x^n=n\log x][/tex]
[tex]=\log (c^2k^3)[/tex] [tex][\because \log (ab)=\log a+\log b][/tex]
Therefore, the required value is [tex]\log (c^2k^3)[/tex].

Find the angle of this sector.
6 cm
NEED ASAP
5 cm
Answer:
x ≈ 68.8°
Step-by-step explanation:
The length of the arc of a sector is calculated as
arc = circumference × fraction of circle , that is
6 = 2πr × [tex]\frac{x}{360}[/tex] = 2π × 5 × [tex]\frac{x}{360}[/tex] = 10π × [tex]\frac{x}{360}[/tex] ( multiply both sides by 360 )
2160 = 10πx ( divide both sides by 10π )
68.7549... = x , that is
x ≈ 68.8° ( to 1 dec. place )

Theodore and Sarah have a small business selling custom-made T-shirts. They currently sell 205 shirts per month and charge $15 per T-shirt. Sarah thinks they can increase their revenue by increasing their selling price, but Theodore knows from experience that each $1 increase in price will decrease the number of T-shirts they sell by 9 shirts per month. Find an expression for the total monthly revenue Theodore and Sarah's business can generate if they change the selling price of their T-shirts. Let x represent the number of $1 increases in the price of the T-shirts.
Answer:
(205-9x) times15
Step-by-step explanation:
The expression the total monthly revenue of Theodore and Sarah's business is (205-9x)15.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Answer:
168 in
Step-by-step explanation:
Pythagoras says:
b² + 56² = 70²
so
b² = 70² - 56²
b = √1764 = 42
so the perimeter is 70+56+42 = 168

Given:
The cost of the T.V. for Colin = £ 800.
The rate of depreciation per year = 4%
Time period = 3 years
To find:
How much will it be worth in 3 years? Give your answer to the nearest penny where appropriate.
Solution:
To solve the above-given problem, we will use the following formula:
where
A = the final value after depreciation
P = the present value
R = rate of depreciation
n = time period
Now, on substituting the given values in the formula, we get
we will round the above answer to its nearest penny where appropriate
≈ £ 708
Thus, the worth of the t.v. in 3 years will be £ 708.

Answer:
radius=6
Step-by-step explanation:
arc ACB=6xPi
Pi=3.14159
arc ACB=18.85 (rounded to 2 places)
ACB is a half circle so a full circle would be 18.85x2 or 37.7
circumference (whole circle)=2 x Pi x radius
37.7=2 x 3.14159 x radius
radius= 37.7/(2 x 3.14159)
radius=6

5.02 Which equation does the graph below represents?
1. y = -1/2x
2. y = -2x
3. y = 1/2x
4. y = 2x
Answer:
2. y= -2x
Step-by-step explanation:
When the line is on an exact point like it is on (-4, 8), we can simplify it by going rise/run
Rise is the same as y (8), and your run is x (-4)
When you divide 8/-4, your answer will be -2
Therefore, the answer is y= -2x

c. 39 units
d. 40 units
Answer:
The correct answer is 39 units.
Parameter is the sum of the lengths of all sides of a polygon. The sides of the polygon are PT, TS, SR, RQ, and QP. To get the length of a side, we use the distance formula:
d =
Each vertex in the polygon has its corresponding points:
P (-2,11)
T (8, 7)
S (1, 7)
R (2, 0)
Q (-4,5)
So to get the length of side PT, we use the distance formula and the vertices of side PT:
P = (-2, 11)
T = (8, 7)
The length of PT is
The same procedure is done for the other 4 sides and the following are the answers:
TS =
SR =
RQ =
QP =
And by adding all the sides, you get the perimeter:
By rounding off, the answer is 39 units.
