Answer:

If a is positive, the parabola will open to the right, so the answer is C

Step-by-step explanation:

The function that gives the amount of money in dollars, j(n), in Jamie’s account n years after the initial deposit is J(n) = P(1 + (r/3)/100)³ⁿ.

Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.

We know the formula for compound interest is,

A = P(1 + r/100)ⁿ.

Where, A = amount, P = principle, r = rate, and n = time in years.

Given, Jamie deposits $627 into a savings account and the account has an interest rate of 3.5%, compounded quarterly.

P = $627, r =  3.5%.

We know the formula for compound interest compounded quarterly is

A = P(1 + (r/3)/100)³ⁿ.

Or

J(n) = P(1 + (r/3)/100)³ⁿ. (here t is replaced by n).

The number of students who would have a pet out of a population of 134 is equal to 90.

Percent of students did not have pet = 33%

Total number of students = 134

Number of students who do not have a pet

= 33% × 134

= 0.33 × 134

= 44.22

Since we cannot have a fraction of a student.

Round 44.22 to the nearest whole number which is 44.

This means that 44 out of the 134 students surveyed did not have a pet.

The number of students who have a pet

= subtract the number of students who do not have a pet from the total number of students.

⇒ Number of students who have a pet = 134 - 44

⇒ Number of students who have a pet  = 90

Therefore, approximately 90 students out of a population of 134 have a pet.

The expression g = f/2 represents the relationship between g and f if j = h and k = m option (A) is correct.

The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

It is given that:

If j = h and k = m

From the figure angle, C is a right-angle triangle as j = h and k = m

From the definition of the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides

h² +k²= g²

From the triangle ΔABC

(j + h)² +(m + h)² =f²

(h + h)² +(k+ k)² =f²

(2h)² +(2k)²=f²

4h²+ 4k²= f²

4(h²+k²)= f²

4×g² =f²

(2g)² = f²

2g=f

g = f/2

Thus, the expression g = f/2 represents the relationship between g and f if j = h and k = m option (A) is correct.

In cylindrical coordinates, the point (-9, 9, 9) is represented as (sqrt(162), π/4, 9), where r = sqrt(162), θ = π/4, and z = 9.

To change the point (-9, 9, 9) from rectangular coordinates to cylindrical coordinates, we need to determine the corresponding values of the radial distance (r), azimuthal angle (θ), and height (z).

The radial distance (r) can be found using the formula: \(r=\sqrt{x^2 + y^2}\)

In this case, x = -9 and y = 9: \(r= \sqrt{(-9)^2 + (9)^2} = \sqrt{81+81} = \sqrt{162}\)

The azimuthal angle (θ) can be found using the formula: θ = a tan2(y, x)

In this case, x = -9 and y = 9: θ = atan2(9, -9)

Since both x and y are positive, the angle θ will be in the first quadrant: θ = a tan2(9, -9) = π/4

The height (z) remains unchanged, which is 9 in this case.

Therefore, in cylindrical coordinates, the point (-9, 9, 9) is represented as (sqrt(162), π/4, 9), where r = sqrt(162), θ = π/4, and z = 9.

The probability of winning at least once when playing the instant lottery twice is 0.19, or 19%.

To find the probability of winning at least once in the instant lottery when playing twice, we can use the complement rule.

The complement rule states that the probability of an event occurring (in this case, winning at least once) is equal to 1 minus the probability of the event not occurring (in this case, not winning both times).
Determine the probability of not winning in a single game, which is 1 - 0.1 = 0.9.
Calculate the probability of not winning both times, since outcomes are independent, by multiplying the probabilities of not winning each time: 0.9 * 0.9 = 0.81.
Finally, find the probability of winning at least once by subtracting the probability of not winning both times from 1: 1 - 0.81 = 0.19.

Answer:

2=(9-3x)/y......1 2= 3y(3-x)..........2

Combining equations 1 and 2;

9-3x=3y²(3-x)

3(3-x)=3y²(3-x)

y²=1

y=√1

y= ±1

Answer:

D and C

Step-by-step explanation:

Given the 2 equations

3x - y = 5 → (1)

2x + 3y = - 15 → (2)

Multiplying (1) by 3 and adding to (2) will eliminate the y- term

9x - 3y = 15 → (3)

Add (2) and (3) term by term to eliminate y

11x + 0 = 0

11x = 0 ⇒ x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 3y = - 15

0 + 3y = - 15

3y = - 15 ( divide both sides by 3 )

y = - 5

solution is (0, - 5 )

Answer: 81,000

Step-by-step explanation:

We can solve this by using the formula given.

If f(1)=1000x3^1, then 1,000x3=3,000

If f(2)=1000x3^2, then 3^2=9 and 1000x9=9000,

and so on,

Now, f(4) will equal 1000x3^4, and 3^4 is 3x3x3x3, which is 9x9 or 9^2, which would be equal to 81, and 81x1000=81,000

To complete the table of values for the exponential function f(x) = 1000*3^x, we can evaluate the function for x = 0, 1, 2, 3, and 4, since we are interested in the number of bacteria on the phone after 4 hours.

x f(x)

0 1000

1 3000

2 9000

3 27,000

4 81,000

Therefore, after 4 hours, there will be 81,000 bacteria on the surface of the phone, assuming the number of bacteria triples every hour and can be described by the exponential function f(x) = 1000*3^x.

The total number of permutations of the four digits is 4 x 3 x 2 x 1 = 24.

To calculate the probability that the password for the school's grading system is composed of a one, a two, a three, and a four, we need to use the formula for permutations. A permutation is the number of ways that objects can be arranged in a specific order. In this case, we want to know the number of permutations of the four digits that make up the password.

There are nine possible digits to choose from, but we need to choose four specific digits: one, two, three, and four. The first digit can be any of the four digits we need, so there are four choices. The second digit can be any of the remaining three digits, so there are three choices. The third digit can be any of the remaining two digits, and the fourth digit must be the remaining digit.

Therefore, the total number of permutations of the four digits is 4 x 3 x 2 x 1 = 24. However, this is only the numerator of the probability fraction. The denominator is the total number of possible 4-digit passwords, which is 9 x 8 x 7 x 6 = 4,536.

So the probability that the password for the school's grading system is composed of a one, a two, a three, and a four is 24/4,536, which simplifies to 1/189. This means that there is a very small chance of the password being composed of these specific digits.

Answer:

-4<x<-2

Step-by-step explanation:

The first thing you do to solve this problem is to look at the limits: -3x-4 should be higher than 2 and lower than 5.

You first find what x should be for -3x-4  to equal 2. After solving, you get that x should be -2 for the equation to be equal to 2.

You then find what x should be for -3x-4 to equal 5. After solving, you get that x should be -4 for the equation to be equal to 5.

Since x can't be -2 or -4, because -3x-4 should be greater than 2 and less than 5, the solutions for x are going to be between -2 and -4.

This is why the answer to this problem is -4<x<-2.
