Answer:

no real solutions

Step-by-step explanation:

The discriminant is

b^2 -4ac

Where ax^ +bx+c

x^2-3x+4

so a=1  b = -3  c=4

(-3)^2 -4(1)(4)

9 - 16

-7

Since the discriminant is less than 0 there are no real solutions

Mashcka [7]

6x = 90

  x = 90/6

  x = 15

4x + 10y = 90

4(15) + 10y = 90

60 + 10y  = 90

10y = 30

y = 3

Answer: Last option

x = 15, y = 3

Option (A) :  least: 10 hours; greatest: 14 hours

The function f(x) = sin x has all real numbers in its domain, but its range is

−1 ≤ sin x ≤ 1.

How to solve such range questions?

Such questions in which every term is in addition and its range is asked is simplest ones to solve if we know the range of each of term. This can be seen from this question

Given: d(t) = 2sin(xt) + 12

=  −1 ≤ sin (xt) ≤ 1.

=  −2≤ 2 sin (xt) ≤ 2.

=  10 ≤ 2sin (xt) + 12 ≤ 14

=   10 ≤d(t) ≤ 14

Thus  least: 10 hours; greatest: 14 hours
