Answer: F
Step-by-step explanation:
We know the angle is in the first quadrant, so its argument is in between 0 and 90 degrees.
This eliminates D and E.Also, its modulus is the distance from the origin, which in this case is [tex]\sqrt{3^2 + 1^2}=\sqrt{10} \approx 3.16[/tex]

Peter has 5 times as much Money as Bala.
They have $1674 in total.
How much more money has Peter than bala
Answer:
Bala = 279$
Peter = 1395$
Step-by-step explanation:
Peter has 5 times as much Money as Bala.
They have $1674 in total.
How much more money has Peter than bala
Bala has 1 unity
Peter has 5 unity
total unity = 6
Find 1 unity
1674 : 6 = 279
Bala = 279
Peter = 5 * 279 = 1395
Angles A and B are complementary. If sin A = 5x + 9 and cos B = 3x + 21, what is the value of x? (1 point) 2 6 15 39
The value of x is 6.
What are complementary?Complementary angles are angles that sum up to 90°.
Analysis:
For angles A and B, to be complementary, the sine of angle A must be equal to the cosine of angle B.
sin A = cos B
5X+9 = 3x+21
5x - 3x = 21 - 9
2x = 12
x = 6
In conclusion, the value of x to make angles A and B complementary is 6.

Rita is ordering 4 bags of cat food from canada. each bag has a mass of 2.5kg . to determine the shipping costs, rita needs to know the total weight in pounds. what is the weight of the cat food in pounds?
Answer:
total weight in pounds = 22 lb
Step-by-step explanation:
Let's first find out the total weight in kilograms.
total weight = 4 x 2.5 kg = 10 kg
The approximation for kilograms (kg) to pounds (lb) is 1 kg = 2.2 lb.
So if 1 kg is 2.2 lb, 10 kg is 10 times more.
10 kg = 10 x 2.2 lb = 22 lb
Suav left his house at time zero and drove to the store, which is 8 blocks away, at a speed of 4 blocks per minute. Then he stopped and went into the store for 2 minutes. From there, he drove in the same direction at a speed of 4 blocks per minute until he got to the bank, which is 16 blocks away from the store. He stopped at the bank for 4 minutes. Then he drove home at a speed of 6 blocks every minute. Make a graph of showing the number of blocks away from home that Suav is xx minutes after he leaves his house, until he gets back home.
The graph for Suav's trip is attached along with the values derived from the information provided.
What is the explanation for the graph?The key to understanding the graph is that every time spent while he was on the way to the back and back are all added cumulatively.
So when he stops at the store which is 8 blocks away from home, the time spent is recorded as 4 + 2 at location 8 blocks.
It is also to be noted that the time spent is plotted on the x-axis and the blocks away from home on the y-axis.

For what values of x and y is quadrilateral ABCD a parallelogram?
Answer:
x = 6 y = 4Step-by-step explanation:
AB = DC
AD = BC
we use AB and DC
6x - 26 = 8x - 38
-26 + 38 = 8x - 6x
12 = 2x
x = 12 : 2
x = 6
---------------
check
6 * 6 - 26 = 8 * 6 - 38
36 - 26 = 48 - 38
10 = 10
the answer is good
now we use AD and BC
6y + 12 = 3x + 24
-3x + 6y - 12 = 0
3y - 12 = 0
3y = 12
y = 12 : 3

The population of a town is growing exponentially and can be modeled by the
equation f(t) = 42. e(0.015). The population is measured in thousands, and time is
measured in years 1950.
C. According to this model approximately what is the population in 1960?
The population of the town in 1960 is 48.80 thousands
How to determine the population in 1950?The equation of the model is given as:
f(t) = 42e^(0.015t)
1960 is 10 years after 1950.
This means that:
t = 10
Substitute t = 10 in f(t) = 42e^(0.015t)
f(10) = 42e^(0.015 * 10)

or
AM/(AM + MB) = AN/(AN + NC)
Check if this is true:
AM/AB = 21/(21 + 9) = 21/30 = 7/10
AN/AC = 14/(14 + 6) = 14/20 = 7/10

According to a study, 45% of americans have type o blood. if a random number generator produces three-digit values from 000 to 999, which values would represent those having type o blood
The values that represent those having type O blood are the values from 000 to 449.
How to determine what range of the RNG should we use?
RNG refers to a random number generator, this means that from 000 to 999 (a total of 1000 numbers) each has the same probability of being randomly selected by the program.
Then, if we want to represent a probability of the 45%, then 0.45 of the number of elements must be assigned to what we want to represent (having type O blood).
0.45*1000 = 450
Then we can assign the first 450 numbers to have type O blood, the first 450 numbers are: {000, 001, ..., 449}
So the values that represent those having type O blood are the values from 000 to 449.
