Kristin drew a triangle with 2 congruent sides and 1 obtuse angle. Which term accurately describes the triangle? Mark all that apply. A. Isosceles B. Scalene C. Acute D. Obtuse
Answers
The terms accurately describes the triangle which Kristin drew with 2 congruent sides and 1 obtuse angle are obtuse and isosceles triangle.
What are types of triangle?
A triangle is the closed polygon, which has three sides and three angles.
On the basis of angles of a triangle, the triangle can be divided into 3 types as,
- Acute triangle-Acute triangle is the triangle, in which the all the three interior angle of the triangle measure less than 90 degree. If the sum of the square of the two littler sides is greater than the square of the third side, then it is an acute triangle.
- Obtuse triangle-Obtuse triangle is the triangle, in which one of the interior angle of the triangle measure more than the 90 degree. . If the sum of the square of the two smaller sides is less than the square of the third side, then it is an obtuse triangle.
- Right triangle-Right triangle is the triangle, in which one of the interior angle of the triangle measure equal to the 90 degree. If the sum of the square of the two smaller sides is equal to the square of the third side, then it is a right triangle.
Kristin drew a triangle with 2 congruent sides. This two equal sides make the triangle Isosceles.
Her triangle has 1 obtuse angle. This makes his triangle Obtuse. Thus, she drew an obtuse Isosceles triangle.
Thus, the terms accurately describes the triangle which Kristin drew with 2 congruent sides and 1 obtuse angle are obtuse and isosceles triangle.

The blades of a windmill turn on an axis that is 30 feet from the ground. The blades are 10 feet long and complete 2 rotations every minute. Write a sine model, y = asin(bt) + k, for the height (in feet) of the end of one blade as a function of time t (in seconds). Assume the blade is pointing to the right when t=0 and that the windmill turns counterclockwise at a constant rate.

Answer:
x = 4 or x = 12
Step-by-step explanation:
Given:
y = -10x² + 160x - 430
When y = $50
50 = -10x² + 160x - 430
50 + 430 = -10x² + 160x
480 = -10x² + 160x
-10x² + 160x - 480 = 0
Divide through by -10
x² - 16x + 48 = 0
Solve the quadratic equation using factorization method
+48 = -12 × -4
-16 = -12 -4
Therefore,
-12 and -4 are both factors
x² - 16x + 48 = 0
(x - 4 )(x - 12 ) = 0
x - 4 = 0
x = 4
OR
x - 12 = 0
x = 12
Answer:
Replace y in the equation with 50: (50 = -10x2 +160x - 430) Use factoring to solve the equation. After writing the equation in standard form and dividing each side by -10, it is easy to factor as 0 = (x - 4)(x - 12).

Final answer:
The solution to the inequality 2x³ – 3x² – 14x ≥ 0, as indicated by the graph provided, is given by the intervals of x where the function is increasing. Therefore, the solution is comprised of the intervals [-2, -1] and [3.5, ∞].
Explanation:
The solution to 2x³ – 3x² ≥ 14x can be found by solving the inequality. First, let's rearrange the inequality to: 2x³ – 3x² – 14x ≥ 0. This equation represents where the function is positive (above the x-axis) on the graph. Therefore, we must identify the intervals of x where the function increases or decreases.
Based on the description of the graph, the function increases in the intervals (-2, -1) and (3.5, ∞) and decreases in the interval (-1, 3.5). So, the solution to the inequality would be the union of the intervals where the function increases: [-2, -1] U [3.5, ∞].

Answer:
$385.00 = $85.00 * 3.647 + $75.00
Step-by-step explanation:
The equation that best represents the situation is:
Total Cost = Hourly Rate x Repair Time + Diagnosis Fee
In this case, the hourly rate is $85.00 and the diagnosis fee is $75.00. We are given that the total cost is $385.00. Let's represent the repair time as "t" in hours.
So, we can write the equation as:
$385.00 = $85.00 * t + $75.00
To solve for the repair time "t", we need to isolate the variable.
First, we subtract $75.00 from both sides of the equation:
$385.00 - $75.00 = $85.00 * t
Simplifying, we get:
$310.00 = $85.00 * t
Next, we divide both sides of the equation by $85.00 to solve for "t":
$310.00 / $85.00 = t
Using a calculator, we find that t is approximately 3.647, which means the repair time is approximately 3.647 hours.
Therefore, the equation that best represents the situation is:
$385.00 = $85.00 * 3.647 + $75.00
