Answer:

874, 2445, 95, 27

Step-by-step explanation:

0 = 0

1 = 1

2 = 2

3 = 3

4 = 4

5 = 5

6 = 6

7 = 7

8 = 8

9 = 9

A = 10

B = 11

C = 12

D = 13

E = 14

F = 15

36A = 3 * 16^2 + 6 * 16^1 + 10 * 16^0 = 874

98D = 9 * 16^2 + 8 * 16 + 13 = 2445

5F = 5 * 16 + 15 = 95

1B = 1 * 16 + 11 = 27

I need help with this question

Answer:

Option B is correct

Step-by-step explanation:

Given:

f(x) = -20x^2 +14x +12 and

g(x) = 5x - 6

We need to find f/g and state its domain.

f/g = -20x^2 +14x +12/5x - 6

Taking -2 common from numerator:

f/g = -2(10x^2 - 7x - 6) / 5x -6

Factorize 10x^2 - 7x - 6= 10x^2 - 12x +5x -6

Putting in the above equation

f/g = -2(10x^2 - 12x +5x -6)/ 5x -6

f/g = -2(2x(5x-6) + 1 (5x-6)) / 5x-6

f/g = -2 ( (2x+1)(5x-6))/5x-6

cancelling 5x-6 from numerator and denominator

f/g = -2(2x+1)

f/g = -4x -2

The domain of the function is set of all values for which the function is defined and real.

So, our function g(x) = 5x -6 and domain will be all real numbers except x = 6/5 as denominator will be zero if x=5/6 and the function will be undefined.

So, Option B is correct.

A function, f(x) = 4x + 5, has a domain 0 < x < 50. What is its range?
Roman55 [17]

Answer:

f(x) = 4x+5 ; 0 ≤ x ≤ 50

 

The range is the possible output values of f(x)

 

4(0) + 5 = 5       smallest output value in range

4(50) + 5 = 55    largest output value in range

 

The outputs are between 5 and 55 including the endpoints so

the range is [5, 55]

choose the equation that shows a step in the process of completing the square on the given quadratic. y = x2 8x – 3 y = x2 8x 8
posledela
Y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16

ILL BRAINLIEST YOU PLEASE HELP ME
Rudik [331]

Answer:

AS IT IS RIGHT ANGLE .

THEREFORE, 1 ANGLE =90°

A=55°,

LET LAST ANGLE BE Y.

THEREFORE, Y=90-55=35°

RATIO OF A:Y=55:35=11/7

RATIO OF ANÔTHER SIDE :X=11:7

HYPOTENOUES=8

THEREFORE8^2=11X^2+7X^2
