Step-by-step explanation:

ABCD : EFGH = 4 : 3

Therefore AD : EH is also 4 : 3.

We are given that EH = 60,

Hence AD : (60) = 4 : 3, AD = 80. (D)

Christian wants to make an A in his class. There are 5 exams this year, and he has taken 4 of them. His grades were 84, 88, 95,

ioda

Answer:

last test grade=x x ≥ 79 so 79%

Step-by-step explanation:

(84/5)+(88/5)+(95/5)+(104/5)+(x/5) ≥ 90

Simplify: (371/5)+(x/5) ≥ 90

Subtract (371/5) from both sides

Then you have (x/5) ≥ (79/5)

Then multiply both sides by 5 and you have x ≥ 79

. What are the exact solutions of x2 - x - 4 = 0?

Dimas [21]

X ² - x - 4 = 0
$x_{1} = \frac{1+ \sqrt{1+16} }{2}= \frac{1+ \sqrt{17} }{2} = 2.56$
$x_{2} = \frac{1- \sqrt{17} }{2}= - 1.56$
Exact values are x 1 = 2.56 and x 2 = -1.56

Given f(x) = √x and g(x) = x+2 find the domain of f(g(x)).

REY [17]

Answer:

E) None of the above

Step-by-step explanation:

Given $f(x)=\sqrt{x}$ and $g(x)=x+2$ , then $f(g(x))=\sqrt{x+2}$ . This shifts the graph of the parent function $f(x)=\sqrt{x}$ 2 units to the left. Thus, the domain of the function is $[-2,\infty)$ , making none of the above true.
