PLEASE HELP, easy. <br> What are the exact solutions of x^2-5x-7=0 ?
Svetlanka [38]
X^2 - 5x - 7 = 0

x = (-b (+-) b^2 - 4ac) / 2a
a = 1, b = -5, c = -7

x = (-(-5) (+-) sqrt (-5^2) -4(1)(-7)) / 2(1)
x =  (5 (+-) sqrt 25 + 28) / 2
x = (5 (+-) sqrt 53) / 2

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

So

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.

URGENT PLEASE ANSWER <br> inverse function<br> *see attachment*
Mila [183]

Answer:

Horizontal shift to the RIGHT of <u>one unit</u>

Step-by-step explanation:

When looking at a square root equation, the transformation form is:

f(x) = a\sqrt{b(x-h)} +k

'h' represents a horizontal shift of the graph. Therefore, in this instance:

f(x) = \sqrt{x-1}

This means that there is a horizontal shift to the RIGHT of <u>one unit.</u>

A 51 foot piece of wire is cut into 3 sections so that the first section is three times as long as the second section and the se
kirill [66]

Answer:

The length of the longest section x = 36 ft

Step-by-step explanation:

Total length of the wire = 51 ft

Let first section of wire = x

Second section of wire = y

Third section of wire = z

According to given data

x = 3 y & y = 4 z

Total length of the wire = x + y + z = 51

y + 3 y + \frac{y}{4} = 51

\frac{17}{4} y = 51

y = 12

x = 3 × 12 = 36

z = \frac{y}{4} = \frac{12}{4} = 3

Therefore the length of the longest section x = 36 ft
