7 0

Answer:

x = - 1/6 + √-119/6, and, - 1/6 - √-119/6

Step-by-step explanation:

Using the quadratic formula which is: - b ± √b² - 4ac / 2a

a = 3, b = 1, c = 10

- 1 ± √1² -4 * 3 * 10 / 2 * 3

- 1 ± √1 - 120 / 6

-1 ± √-119 / 6

= -1/6 + √119/6,               or                  - 1/6 - √-119/6

In the figure shown, r || s. If the measure of ∠ 2 = 146°, what is the measure of ∠ 7
borishaifa [10]

Answer:

34°

Step-by-step explanation:

1. First, let's find the measure of ∠1 because since r || s, that means ∠1 = ∠7 because they're both alternate exterior angles. Alternate exterior angles are congruent.

2. (Solving for ∠1)

  • 146 + x = 180
  • 146 + x - 146 = 180 - 146
  • x = 34

3. Now, since we know ∠1 = ∠7, ∠7 = 34°.

Please answer with a detailed explanation.
Alecsey [184]

From a tee box that is 6 yards above the ground, a golfer hit a ball. The Domain of the function is [0,230].

Given that,

In the picture there is a question with a graph.

From a tee box that is 6 yards above the ground, a golfer hit a ball. The graph displays the height of the golf ball above the ground in yards as a quadratic function of x, the golf ball's horizontal distance from the box in yards.

We have to find the domain of the function in the situation.

The domain is nothing but All of a function's x-values, or inputs, make up the domain, and all of a function's y-values, or outputs, make up the range.

The domain of a graph is every value in the graph, from left to right. The graph's entire range, from lower to higher numbers, represents the range.

Therefore, the Domain of the function is [0,230].
