The rate of change for the interval between 0 and 2 for the quadratic equation f(x) = 2x^2 + x - 3, represented in the table, is 6.
To find the rate of change for the interval between 0 and 2 for the quadratic equation f(x) = 2x^2 + x - 3, we can use the values provided in the table.
First, let's calculate the values of f(x) for x = 0 and x = 2:
For x = 0: f(0) = 2(0)^2 + 0 - 3 = -3
For x = 2: f(2) = 2(2)^2 + 2 - 3 = 9
Now, we can find the rate of change by calculating the difference in the values of f(x) divided by the difference in x for the interval [0, 2]:
Rate of change = (f(2) - f(0)) / (2 - 0)
Substituting the values we found:
Rate of change = (9 - (-3)) / (2 - 0)
= (9 + 3) / 2
= 12 / 2
= 6

Answer:

Step-by-step explanation:
Maria is 4 ft 2in tall. To find the height of a flagpole, she measured her shadow and the pole's shadow . What is the height h of the flagpole?
Answer:
25 ft
Step-by-step explanation:
The height of the flagpole, using trigonometric ratio is 25feet.
The tangent of angle C will be the ratio of Maria's height to her shadow.
What is the tangent of an angle?The tangent of an angle is the ratio of opposite side to the adjacent side.
It is given that,
Her height = 4 ft 2 inch = 25/6 feet
Length of her shadow =10/3 feet
So, tan C = (25/6)/(10/3)
tan C = 5/4
We know that ∠C and ∠T will be equal
So, tan C = tan T = h/20
5/4 = h/20
h =25
Therefore, The height of the flagpole, using is 25feet.

Step-by-step explanation:
Answer:
w = -1.5u + 2
or
w = -3/2u + 2
Step-by-step explanation:
Your goal is to isolate w
-12u + 13 = 8w - 3
+3 +3
-12u + 16 = 8w

The angles in a triangle are in the ratio 1 : 2 : 3. Find the size of each angle in the triangle.
Answer:
30°,60°,90°
Step-by-step explanation:
All angles in a triangle added up make 180°. Add all numbers in the ratio and divide 180° by it. 180°÷6=30 so 1 in the ratio expression is equal to 30°. Because we know this, we can multiply each number in the ratio by 30° to get the answer above
Solve for the value of a.
Answer:
7 will be the answer.
Step-by-step explanation:
The angles are complementary angles i.e their sum is 90°.
(5a+3)°+52°=90°
5a+55°=90°
5a=90°-55°
5a=35°

AUTHORITY ? description In your own words .this phrase has probably done more damage to investors than just about any other in all of market history.
Answer:
Authority is the accepted power of a person or an organization to lead another person or group. In a political sense, authority also stands for the power and dominion over an area or country held by the government. Authority legitimized by law or government is called 'competent authority'. A person who is generally respected by knowledge or status in a certain area is 'authoritative' in that area.
Authority regulates the relationships between people in society. If authority is absent, anarchy reigns. The difference between authority and power is that authority is legitimate. It has the right to exercise this power by, for example, imposing sanctions.

In triangle FGH shown below, what is the measure of < F degrees?
Record your answer and fill in the bubbles on your answer document. Be sure to use
the correct place value.
Answer:
∠F = 19.5°
Step-by-step explanation:
The sum of all of the angles in a triangle is 180°
∠F + ∠H + ∠G = 180°
∠F + 127° + 33.5° = 180°
∠F + 160.5° = 180°
-160.5° -160.5°
∠F = 19.5°
