Given the function {f(x)=32-x}^{2}f(x)=32−x 2 , what is f(-5)f(−5)?
erastova [34]

Step-by-step explanation:

the description is very difficult to understand with special characters and potential typing errors.

I suspect the definition is

function(x) = 32 - x²

function(-5)function(-5) is then very easily calculated.

we need to calculate function(-5) and then square the result, as function(-5)function(-5) is just a simple multiplication of the function results.

function(-5) = 32 - (-5)² = 32 - 25 = 7

so,

function(-5)function(-5) = 7 × 7 = 49

Find the length here
Vera_Pavlovna [14]

Answer:

The correct answer is

D) 66.35

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

The tangent of the angle = the length of the opposite side. the length of the adjacent side.

So in shorthand notation:

sin = o/h   cos = a/h   tan = o/a

Someone quickly hell
Elza [17]

Answer:

£3,780

Step-by-step explanation:

Total rows = 19 rows

Seats per row = 28 seats

Cost of tickets per seats = £8.75

Total number of seats at the concert = Total rows × seats per row

= 19 rows × 28 seats

= 532 seats

The tickets for 100 seats have not been sold

Total number of tickets = sold tickets + unsold tickets

532 = sold tickets + 100

532 - 100 = sold tickets

432 = sold tickets

Sold tickets = 432 tickets

Total cost estimate of sold tickets = sold tickets × cost of tickets per seats

= 432 × £8.75

= £3,780
