Answer 1

Answer:

Answer:

Graph A

Step-by-step explanation:

Since it is not equal to, the line would be dotted. The y-intercept is at 2 and the slope is 3/4. Since y is less than 3/4x+2, the shaded portion would be below so, the correct graph out of all the options would be Graph A.

S = vt + 16t2 for v.

Answers

Answer:

s = vt + 16t^2

s -16t^2 = vt

s/t -16t = v

Answer:

v = s/t -16t

Step-by-step explanation:

If x/yis rational, must x and y each be rational?
A) Yes; because the quotient of rationals is rational.
B) No; because x and y could have a common irrational factor.
C) No; because the quotient of irrationals is always irrational.
D) Yes; because x and y must be integers, and integers are rational.

Answers

The answer is B.

Consider the fraction $(6 √(5) )/(√(5))$ .

Both the numerator and denominator, when by themselves, are irrational.

However, when they are divided, they result in the rational number $(6 √(5) )/(√(5))=\boxed{6}$ .

When $p,q$ have the same irrational factor, the irrational factor will be cancelled from the fraction and (possibly) leave a rational number.

Answer: The answer is B.

Step-by-step explanation:

No; because x and y could have a common irrational factor.

Answers

You have to cross multiply (multiply the numerator of the first by the denominator of the second and the numerator of the second by the denominator of the first).

$(x+4)/(3) = (4)/(10)$

$10x+40=12$

$10x = -28$

$x=-2.8$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[21]

$(4)/(n+8) = (10)/(8)$

$32 = 8n + 64$

$8n = -32$

$n=-4$

$19) (x + 4)/(3) = (4)/(10) \n \n x + 4 = (4)/(10) * 3 \n \n x = 1.2 - 4 = -2.8 \n \n x = -2.8 \n \n \n 20) (4)/(n+8) = (10)/(8) \n \n 32 = 8n + 64 \n \n 8n = 32 -64 = -32 \n \n 8n = -32 \n \n n = -4$

Which of the following represents the zeros of f(x) = 3x^3 − 10x^2 − 81x + 28?A) 7, -4, 1/3
B) 7, -4, -1/3
C) 7, 4, 1/3
D) 7, 4, -1/3

Answers

Option A). 7, -4 and 1/3

To find the zeros you can factor the polynolial into (3x-1)((x+4)(x-7)

Then:
3x -1 =0 => x = 1/3
x+4=0 => x = -4
x-7 =0 => x =7

Those are the three zeros.
