Answer:

{t | –3 < t ≤ 5}

Step-by-step explanation:

–4 < 3t + 5 ≤ 20

⇔

Archy [21]

Answer:

70.7 ft

Step-by-step explanation:

The triangle formed by home plate, first base, and second base is an isosceles right triangle with hypotenuse 100 ft. Then the side length (base-line distance between bases) is (100 ft)/√2 ≈ 70.7 ft.

___

For an isosceles right triangle with side lengths 1, the hypotenuse can be found from the Pythagorean theorem to be ...

hypotenuse = √(side² + side²) = √(1²+1²) = √2

Then the diamond distances satisfy the proportion ...

hypotenuse/side = 100 ft/(base distance) = √2/1

or ...

base distance = (100 ft)/√2 ≈ 70.71068 ft

We can use the vertex form of a quadratic, $y = a(x-h)^{2} + k$ , to find that $g(x) = a x^{2} - 7$ . Plugging $(x,y)$ ordered pairs into g(x), we see that a = 1. For example, for $(3, 2)$ , $2 = a * 3^{2} - 7$ . Solving for a gives 1.
