Mathematics

Brums [2.3K]2 years ago
7 0

Answer:

4 questions

Step-by-step explanation:

90% is the same as multiplying a number by 0.9. Let's say the number of questions on the quiz is x. This means the amount she got right was 0.9x. We are given this is 36, so we can set them equal and simplify:

0.9x = 36

x = 40

She must have gotten 40 - 36, or 4 questions wrong.

For all values of x, f(x) = x^2 + 1 and g(x) = x-5
Elena-2011 [213]

Answer:

a)  f g(x) =  x³ - 5 x² + x -5

b) g(f(x) =  x³ - 5 x² + x -5

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that f(x) = x² + 1 and g(x) = x-5

a)

      f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26

<u><em>Step(ii):-</em></u>

a) f g(x)  = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5

b)   g(f(x)  = g(x) f(x) = (x-5) (x²+1) =  x³ - 5 x² + x -5

the mode (rounded to the nearest tenth if needed) of the following data set is 30,29,40,51,39,33,24,60,40,35,58
scoray [572]
The mode is the number that occurs the most in the sequence of numbers, so the mode is 40 since that number is repeated the most in the sequence, 2 times.

What is the value of x in the equation 25x^2=16? A.+ 5/4 B.+4 C.+ 4/5 D.+16/25
4vir4ik [10]

Answer:

x = ± 4/5

Step-by-step explanation:

25 x^2 = 16

Divide each side by 25

25 x^2 /25 = 16 /25

x^2 = 16 /25

Take the square root of each side

sqrt(x^2) = ±sqrt(16/25)

We know that sqrt(a/b) = sqrt(a)/ sqrt(b)

x = ±sqrt(16) / sqrt(25)

x = ± 4/5
