Help I’m not sure how to answer this

Mathematics
1 answer:
Drupady [299]3 years ago
8 0

Answer:

option A is the correct choice

Step-by-step explanation:

The trigonometric equation you are using has a general form

y = A* tan w*(x - r)

Where

A is the amplitude of the function

w is the frequency rad/s

r  is the phase shift

In your case

A = 2

B = w = 3

r = pi/2

y = 2* tan 3*(x - pi/2)

HELP ASAP!! Someone please help me solve #19 with steps on how to solve?

Answer:

a.9

b. ay=9

xy= 18

Step-by-step explanation:

a. xa=ay (since a is a midpoint that means xa and ay are the same amount).

3x=5x-6

subtract 5x from both sides

-2x=-6

inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)

x=3

so xa=3x. fill in x

3*3 is 9

b. fill in the x

5*3-6

5 times 3 is 15.

15-6=9

(also xa is 9 and they are congruent so both are 9)

ay= 9

add both sides to find xy

9+9=18

xy=18

PartA)What are the transformations are needed in in order to obtain the graph of G(x) from the graph of f(x) Select all that app
iVinArrow [24]

Part A)

Recall that:

1) The function represented by the graph of the function f(x) translated vertically n units up and horizontally m units left is:

f(x+m)+n\text{.}

2) The function represented by the graph of the function f(x) reflected over the x-axis is:

-f(x)\text{.}

Now, notice that g(x) is the function f(x) reflected over the x-axis and then translated vertically 6 units up and horizontally 4 units left.

Answer Part A:

Options B, C, and D.

Part B) To graph g(x) we will reflect the graph of f(x) over the x-axis and then we will translate it vertically 6 units up and horizontally 4 units left.

We know that the graph of f(x)=|x| is:

The above graph reflected over the x-axis is:

Finally, the above graph translated vertically 6 units up and horizontally 4 units left is:

Carlos deposited $7,924 into a savings account 30 years ago. The account has an interest rate of 4.6% and the balance is current
exis [7]

Answer:

n = 1, this means the interest compounds ANNUALLY.

Step-by-step explanation:

Carlos deposited $7,924 into a savings account 30 years ago. The account has an interest rate of 4.6% and the balance is currently $30,541.83. How often does the interest compound?

Compound Interest Formula

: A = P(1 + r/n)^nt

A = Amount after time t

P = Principal (Initial Amount Invested)

r = Interest rate

n = Number of times the interest is compounded

t = time in years

A = $30,541.83

r = 4.6% = 0.046

t = 30

P = $7,924

Hence,

$30,541.83 = $7924(1 + 0.046/n)^30n

Divide both sides by 7924

$30,541.93/$7924 = (1 + 0.046/n)^30n

$30,541.93/$7924 = (n + 0.046/n)^30n

3.8543576477 = (n + 0.046/n)^30n

We take the logarithm of both sides

log 3.8543576477 = log (n + 0.046/n)^30n

Solving for n,

n = 1

Therefore, from the calculation above, since n = 1, this means the interest compounds ANNUALLY.
