<span>1. Given a(t) = 90 - 10 log (t + 2) = 75 or
10*log (t + 2) = 90-75 = 15 or log(t+2) = 1.5 or
(t+2) = 10^(1.5) or t = -2+[10*√10] = 29.622 or 29.6 weeks. hence the option, "a.29.6 weeks" is correct.

Answer:
Length of side :
.
The distance across the canyon is approximately
.
Step-by-step explanation:
- is the length of the side opposite to the angle .
- is the length of the side opposite to the angle .
Apply the law of sine:
.
In other words,
.
However, the value of the angle isn't given. Don't panic. The three interior angles of a triangle shall add up to 180°. Two of the three angles are given. The value of the third angle is implied.
.
Apply the law of sine to find :
.
Refer to the diagram. The distance across the canyon will be
.
Answer:
Given a triangle ABC, Pythagoras' Theorem shows that:
Thus,
The distance formula, gives an equivalent expression based on two points at the end of the hypotenuse for a triangle.
Therefore when given the hypotenuse with endpoints at
We know that the third point of the right triangle will be at
and that the two side lengths will be defined by the absolute values of:
Answer:
Impossible
Step-by-step explanation:
In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:
a = 5; b = -4; c = 3
The quadratic formula is
(ignore the weird capital A)
Substitute a b and c:
Simplify:
Because is the square root of a negative number, the answer would be imaginary.
Therefore, there are not solutions to this equation.
A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.
The graph never meets the x-axis. It looks like this:
