An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3300 and his stock in Company B was worth $4140. The stock in Company A has increased 4% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth Answers fast!
The total percentage increase in the investor's stock account was of 4.55%.
The values of the stocks of Company A and Company B, after the increase are given, respectively, by:
Company A: 3300 x 1.04 = $3432.
Company B: 4140 x 1.05 = $4347.
The total values are given as follows:
Before the increase: 3300 + 4140 = 7440.
After the increase: 3432 + 4347 = 7779.
The percent increase is given by the increase divided by the initial value and multiplied by 100%, hence:
P = (7779 - 7440)/7440 x 100% = 4.55%.
The total percentage increase in the investor's stock account was of 4.55%.

how many 9-digit integers contain exactly 5 zeroes? (recall that the leading digit is never zero! you may enter a formula or an exact numerical value.)
Considering that the leading digit is never zero , then the number of 9 digit integers that can contain exactly 5 zeroes are 367416 numbers .
the number of digits in the number is = 9 digits ;
the number should have exactly five zeroes ,
the number of ways to pick five of the digit positions for the zeroes, since the first digit can’t be zero is = ⁸C₅ ,
There are 9 possible digits for each of other 4 positions as other positions are occupied by 0 ,
So, the total number of possibilities is = ⁸C₅ × 9⁹⁻⁵
Simplifying further ,
we have ,
= ⁸C₅ × 9⁴
= 56 × 6561

Suppose that the height H of a Ferris wheel can be modeled by the function H(t) = -12cos(πt/45) + 18, where t is the time in seconds. What is the maximum height of a cabin? Use 3. 14 for π.
For the given function H(t) = -12cos( πt/45 ) + 18 the maximum height is 30 units.
Function to modeled the height 'H' of the Ferries wheel is given by:
H(t) = -12cos( πt/45 ) + 18
Where 't' represents the time in seconds.
For cosine trigonometric function,
-1 ≤ cosα ≤ 1
Here cos function lies between two values -1 and 1.
Substitute cos( πt/45 ) = 1 or -1
When cos( πt/45 ) = 1
H(t) = -12(1) + 18
⇒H(t) = 6 units
When cos( πt/45 ) = -1
H(t) = -12(-1) + 18
⇒H(t) = 30 units
Maximum height of a required cabin is equals to 30 units.
Therefore, the maximum height of given cabin represented by the function
H(t) = -12cos( πt/45 ) + 18 is equal to 30 units.

Starch and protein levels are checked for In order to present the idea of chemical compound variety, it is necessary to test for the presence of starches and protein macromolecules.
Hypothesis: It is a negative result if the biuret reagent remains blue after a test for protein since the reagent itself is blue. The test for protein is positive if a solution is pinkish purple or purple. The starch test solution is a yellowish brown color. We utilized iodine to test for starch in some solutions if any ingredient produced a mixture that was yellowish brown in color. Polysaccharides, monosaccharides, and disaccharides are separated from starch by iodine.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Total number of employees = 140
Male:
Number of male = 65
Right-handed.

90 - 44 = 46
Left-handed.
= 65 - 46
= 19
Female:
Number of females.
= Total employees - Number of males
= 140 - 65
= 75
Right-handed.

Now,
The frequency table.
RH = 46
LH = 19
Male = 65

A. Fire the manager.

C. Hire more workers.
D. Wait for its workers to improve.
Assuming all the workers employed at the beanbag factory are of equal ability, the beanbag factory invest in more equipment to address the diminishing marginal returns it experiences after the hire of its third worker. So the option B is correct.
It is assumed that all of the factory's employed employees have the same level of skill. Additionally, it must follow that if they are working to their maximum ability, they will be able to accomplish the same amount of work as before.
Since the third man was hired, the quantity of work the three of them have completed has decreased, making it clear that he is to blame for the diminishing returns.

For example, this transformation moves the parallelogram to the right 5 units and up 3 units. It is written ( x , y ) → ( x + 5 , y + 3 ) .
Given:
Pint( -1, 3).
Translating unit = 2 units down
According to the 270°-counterclockwise rotation [90°-clockwise rotation] rule, you take the y-coordinate, move it to your new x-coordinate, and then take the opposite of the x-coordinate and set it as your new y-coordinate:
Extended Rotation Rules
270°-clockwise rotation [90°-counterclockwise rotation] = (x, y) → (-y, x)
270°-counterclockwise rotation [90°-clockwise rotation] =(x, y) → (y, -x)
and, 180°-rotation = (x, y) → (-x, -y)

jane spent 2 hours exploring a mountain with a dirt bike. when she rode the 40 miles uphill, she went 5 mph slower than when she reached the peak and rode for 12 miles along the summit. what was her rate along the summit?
The time to calculate her rate along the summit Rate = 1.5 mph
Rate = Distance / Time
To solve this problem, we will first need to calculate the time it took Jane to reach the peak. Since she rode 40 miles uphill, we can use the rate of 5 mph slower than when she reached the peak to calculate this time.
Time = Distance / Rate
Time = 40 miles / (Rate - 5 mph)
Time = 40 miles / (Rate - 5 mph)
Time = 40 miles / (Rate - 5)
Time = 8 hours
Since Jane spent 2 hours exploring the mountain, the total time it took her to reach the peak was 8 hours. We can now use this time to calculate her rate along the summit.
Rate = Distance / Time
Rate = 12 miles / 8 hours

Answer:
To find the coordinates of Q, we can use the concept of proportional division of line segments.
Given that MQ:ON = 2:3, it means that the ratio of the length of MQ to ON is 2:3.
Let's first find the vector that represents the direction of MN, which is the vector pointing from M to N. We can find this by subtracting the coordinates of M from the coordinates of N:
(8,10) - (-12,-5) = (20, 15)
This is the vector <20,15>
Now, we can find the point Q, which is located two thirds of the way from M to N, by multiplying the vector <20,15> by 2/5 and adding the result to the coordinates of M:
Q = M + (2/5) * <20,15>
= (-12,-5) + (2/5) * <20,15>
= (-12,-5) + <8,6>
