b. y = sin x

c. y = sec x

d. y = cos x

Answer:
### What is an even function?

The **function **is **even **will be y = sec x and y = cos x. Then the **correct **options are **C** and **D**.

**Even Function **- A true function f(x) is said to be an **even **function if the **output **value of f(-x) is the **same **as the f(x) for all **values **of x in the **domain **of f.

The **equation **should be **stored **in an **even **function:

f(-x) = f(x)

**Check **all that apply.

a. y = csc x, then **replace **x with -x. Then we have

y = csc -x

y = 1/sin -x

y = - 1/ sin x

y = -csc x

b. y = sin x, then **replace **x with -x. Then we have

y = sin -x

y = - sin x

c. y = sec x, then **replace **x with -x. Then we have

y = sec-x

y = 1/cos -x

y = 1/ cos x

y = sec x

d. y = cos x, then **replace **x with -x. Then we have

y = cos -x

y = cos x

Thus, the **function **is **even **will be y = sec x and y = cos x.

Then the **correct **options are **C** and **D**.

What value of x makes the equation 7^15⋅7^4=7x true?

Calculate the rent of a decreasing annuity at 8% interest compounded quarterly with payments made every quarter-year for 7 years and present value $78,000.

Determine the truth value of each of these statements if the domain of each variable consists of all real numbers.a) ∀x∃y(x2 = y)

Draw an isosceles Triangle with exactly one 40 degrees angle. Is this the only possibility or can you draw another triangle that will also meet these conditions? How is this different from drawing a triangle given 2 sides and the angle between them?Please answer ASAP Due today PLEASE!!!

**Answer:**

**Step-by-step explanation:**

As it is first order nonlinear ordinary differential equation

Let y(x) = x v(x)

2xy/(x²+y²)=2v/(v^2+1)

dy=xdv+vdx

dy/dx=d(dv/dx)+v

x(dv/dx)+v=(2v)/(v^2+1)

dv/dx=[(2v)/(v^2+1)-v]/x

u=v^2

du=2vdv

Answer:

148.80

Step-by-step explanation:

Take 126.44 multiply by 60 months equals 7586.40

Take 103.30 multiply by 72 months equals 7437.60

Subtract 7437.60 from 7586.40

The total payback for Option A would be $7,586.4 and for Option B it would be $7,437.60. The difference of $148.8 indicates the savings Sky would have by choosing Option B over Option A.

Firstly, to calculate the total payback for each loan, you multiply the number of **payments** by the monthly payment amount. For Option A, that's 5 years times 12 payments per year, times a monthly payment of $126.44. Which gives us a total payback of 5 * 12 * 126.44 = $7,586.4. Next, calculate the payback for Option B in the same way: 6 years times 12 payments per year, times a monthly payment of $103.30. Which gives us 6 * 12 * 103.30 = $7,437.60.

Then, we subtract the total payback of Option B from that of Option A to find the **savings**: $7,586.4 - $7,437.60 = $148.8. So, by choosing option B, Sky would save $148.8.

**Answer:**

I think that is the C

**Step-by-step explanation:**

**Answer:**

Option B is the correct answer.

**Step-by-step explanation:**

here, arc RT =162°

as in question given that the value of arc RT is 162° the value of angle RST is 1/2 of 162°.

so, its value must be 81°only.

Hoped this helped :D

One person will get 76 pieces

Three people will get 78 pieces

One person will get 77 pieces

Three people will get 79 pieces

One person will get 78 pieces

Three people will get 76 pieces

One person will get 75 pieces

The answer is C: three people will get 79 pieces and one person will get 78 pieces.

79x3=237

237+78=315

There were 315 total pieces (200+115) so it has to be C.

Hope this helps!

79x3=237

237+78=315

**Answer:**

11 1/2 years old

**Step-by-step explanation:**

Let Amanda's age be a.

Let the company's age be c.

The company is 24 years older than Amanda. This means that:

c = 24 + a ______(1)

The sum of Amanda's age and the company's age is 121 years. This means that:

c + a = 121 ________(2)

Put (1) in (2):

24 + a + a = 121

2a = 121 - 24

2a = 97

a = 97 / 2 = 48 1/2 years

She has been there for 37 years, therefore, her age when she started working there is:

48 1/2 - 37 = 11 1/2 years old

**NOTE: This age doesn't seem right but I worked based on the parameters given.**
