What is the value of log5 125?

Answer:

cos B = 9/41

tan B = 40/9

sin B = 40/41

Step-by-step explanation:

There is no picture, so I am making a few assumptions.

I am assuming that angle C is the right angle and is opposite 41.

I am also assuming that angle B is formed by the sides that measure 9 and 41. The hypotenuse is 41.

For angle B, the adjacent leg is 9, and the opposite leg is 40.

cos B = adj/hyp = 9/41

tan B = opp/adj = 40/9

sin B = opp/hyp = 40/41

Answer:

1/2=2/4

Step-by-step explanation:

1/4=4/8 - no, if you multiply 1/4 x 4 to get numerator match = 4/32

1/2=2/4 - YES , 1/2 x 2  = 2/4

3/5=5/10 = no if you multiply 3/5 x 2 to get denominator match = 6/10

2/3=3/6 = no if you multiply 2/3 x 2 to get denominator match = 4/6

Answer:

The correct graph that includes a function, its inverse, and a dashed line that verifies the relationship is shown in option 1.

Used the concept of function that states,

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable and another variable.

Ask about the function, its inverse, and a dashed line that verifies the relationship.

Now from the first graph;

The dashed line is y = x.

And the graph shows the functions and their inverse as both graphs are opposite to each other.

Therefore, option 1 is true.

Answer:

Part 1: (n÷2)-7 = -12

Part 2: n = -10

Step-by-step explanation:

Part 1:

Let's first write "the quotient of a number and 2" using numbers and variables. Let "n" represent "a number". The key word that we see here is quotient, meaning we have to divide something by something else. "The quotient of a number and 2 means that "a number" is the dividend (number that is divided) and "2" is the divisor (number that divides the dividend). Therefore we obtain:

n÷2

The first part says "seven less than the quotient of a number and 2". The keyword here is less, meaning we have to use subtraction. Therefore:

(n÷2)-7

The last part says "is equal to -12". Therefore the whole expression we just wrote is equivalent to -12:

(n÷2)-7 = -12

Part 2

Remember the Order of Operations:

Parentheses

Exponents

M/D: Multiplication/Division (whichever comes first in the equation)

A/S: Addition/Subtraction (whichever comes first in the equation)

Start by adding 7 to both sides

(n÷2) = -5

Then, multiply both sides by 2

[tex]\frac{n}{2}=-5\\n=-10[/tex]

Note: I used a fraction to display the division because it is easier to see why we have to multiply both sides by 2; to cancel out the denominator.

The number of years the amount has been in the venture account with 12% interest per year is 4.

Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.

A sum of $2,500 was deposited in a venture account, which pays 12% compounded per year and it accumulated to $3,950.

Then the number of the years will be

We know the compound interest formula

[tex]\rm A = P(1+r)^t[/tex]

where

A = Accumulated amount

P = Deposited value

r = rate of interest

t = time

Then we have

[tex]3950 = 2500 (1.12)^t\\\\1.58\ =1.12^t[/tex]

Taking log both sides, then we have

[tex]\rm \ln 1.58 = t \times \ln 1.12\\\\or \ \ \ \ t = 4.036 \approx 4 \ years[/tex]

Then the number of the years is 4.

The spinner game is an illustration of probability, and the spinner game that is fair is (b) If you spin a number greater than 10, you win.

The number of sections in the spinner is given as:

n = 20

There are 10 numbers greater than 10 i.e. 11 to 2.

So, the probability that a number greater than 10 is spun is:

P = 10/20

P = 0.5

The probability that a number that is not greater than 10 is spun is calculated using the following complement rule

q = 1 - p

This gives

q = 1 - 0.5

Evaluate

q = 0.5

Notice that both probabilities are the equal

((ASSUMING THERES NO TAXES WITH THE PAYMENT))

Step-by-step explanation:
A)

first add up the costs of each item to get the ttal cost with addition as follows...

9.50 + 0.50 + 2.75 + 11.35 ((Adding like terms by adding 0.50 to 9.50 equaling 10.00))

10.00 + 2.75 + 11.35 ((adding the more simple options togeter since .75 is a more common fraction at 3/4))

12.75 + 11.35 ((finnishing off the system by adding the last two numbers together equaling to 24.10))

therefore Thabo spent a total of 24.10

B)
to find out the change, all we need to do is subtract the total cost from the total amount Thabo used to pay as shown below

50.00 - 24.10

in conclusion, Thabo would have R25.90 in change from the transaction ((assuming theres no tax))

Answer:

2,012 is greater than 30

Step-by-step explanation:

The correct solution for the inequality is k > -9.

Given is an inequality -2k + 12 < 30, we need to solve for k,

To solve the inequality -2k + 12 < 30 for k, follow these steps:

Subtract 12 from both sides of the inequality to isolate the term with 'k':

-2k + 12 - 12 < 30 - 12

-2k < 18

Divide both sides by -2, but remember that when you divide an inequality by a negative number, the direction of the inequality sign flips:

(-2k)/(-2) > 18/(-2)

k > -9

So, the correct solution for the inequality is k > -9.

Among the options you provided, the correct answer is: k > -9.

A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.
