Suppose the system below is consistent for all possible values of f and g. What can you say about the coefficients c and d? Just

morpeh [17]

Answer:

The answer is " $d \neq 3c,$ f and g are arbitrary".

Step-by-step explanation:

The matrix of the device is increased

$\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right]$

Reduce the echelon row matrix

$\left[\begin{array}{ccc}1&3&f\\ c&d&g\\ \end{array}\right] \\\\R_1 \leftrightarrow R_2 \\\\\frac{R_2 -1}{C R_1 \to R_2} \sim \left[\begin{array}{ccc} c&d&g\\ 0 & \frac{3c-d}{c}& \frac{cf-g}{c}\\ \end{array}\right]$

Therefore, if 3c $\neq$ 0 is d $\neq$ 3c, the device is valid. Therefore d $\neq$ are arbitrary 3c, g and f.

1. Erin hits a golf ball off a tee. The height, yin yards, of the ball off the ground is given by

Sladkaya [172]

Answer:

The maximum height of the ball is 28.2 yards.

Step-by-step explanation:

When we have a quadratic equation in the following format:

$y = ax^{2} + bx + c$

The maximum value happens when

$x = x_{v} = \frac{-b}{2a}$

The maximum value will be $y(x_{v})$

In this problem, we have that:

$y = -0.0018x^{2} + 0.45x + 0.05$

$a = -0.0018, b = 0.45, c = 0.05$

$x = x_{v} = \frac{-b}{2a} = \frac{-0.45}{2*(-0.0018)} = 125$

The maximum height is:

$y(125) = -0.0018*(125)^{2} + 0.45*125 + 0.05 = 28.2$

The maximum height of the ball is 28.2 yards.

19. Parkash had just enough money to buy 100 pencils. However, he bought only 70 pencils and had $4.50 left. What was the cost o

prisoha [69]

Answer:

since the unknown amount can buy 100 pencils

he bought 70 pencils

therefore $4.50 can buy 30 pencils

so 1 pencils cost $4.50 /30=0.15
