What is the value of f(x) when x = 4 in the piecewise function f(x) = 2x² when x>4
zepelin [54]

Answer:

16

Step-by-step explanation:

f(x) = 2x² when x>4

We cannot use this expression of f to calculate f(4)

because ,this expression define f for the value of x

that are greater (not equal) than 4.

………………………………………………………

f(x) = 4x when x ≤ 4 , here x is can be equal to 4

(notice the sign ≤ )

Therefore

f(4) = 4 × (4) = 16

A university has 10,000 students of which 55% are male and 45% are female. if a class of 30 students is chosen at random from th
irina [24]
Information provided:

Sample size, n = 30 students
P(Male), P(m) = 55% = 0.55
P(Female), P(f) = 45% = 0.45

Now,
Mean = nP(m) = 30*0.55 = 16.5 ≈ 17 students

Variance = (sd)^2 = nP(m)P(f) = 30*0.55*0.45 = 7.425 ≈ 8 students

What is the missing constant term in the perfect square that starts with X^2 - 8x
xenn [34]

Answer:

16

Step-by-step explanation:

Perfect square in the quadratic from ax² + bx + c

You know an equation is perfect when:

2√(ax²)√(c) = bx

Substitute x² for ax² and 8x for bx. Then isolate c by doing the reverse operations.

2√(ax²)√(c) = bx

2√(x²)√(c) = 8x

2x√c = 8x   Divide both sides by 2x

√c = 4    Square both sides to isolate c.

c = 16

The missing constant term is 16.

Check answer:

x² - 8x + 16

(x - 4)²

= (x - 4)(x - 4)

= x² - 4x - 4x + 16

= x² - 8x + 16

7. A photograph negative measures 15 inches by
ella [17]

Answer:

First we need to set a proportion

Currently the negative measures 15 inches by 2 inches. And the longer dimension of the printed version is 4 inches. Therefore:

\frac{2}{y} = \frac{15}{4}

15y = 8

y = 0.5333

Therefore, the dimension of the shorter dimension is 0.5333.

None of the options matches this response, so maybe you forgot to add some information?
