given the equation f(x)=-2x²+4x+6 find the average rate of change from x=1 and x=2
Answer:
16
Step-by-step explanation:
1) Plug x=1 into equation
f(x) = -2(1)²+4(1)+6
f(x) = -2²+4+6
f(x) = 4+4+6
y = 14
(1,14)
2) Plug in x=2 into equation
f(x) = -2(2)²+4(2)+6
f(x) = -4²+8+6
f(x) = 16+8+6
y = 30
(2,30)
3) Use slope formula (\(\frac{y2-y1}{x2-x1}\))
\(\frac{30-14}{2-1}\)

What is the range of f(x) = 3* + 9?
O {yly<9}
O {yly>9}
O {yly> 3}
O {yly<3}
On solving the provided question, we can say that - the range \(|x + 1| = 0\) \(x + 1 = 0 = > x = -1\) and \(y = 3\)
What is range?Finding the variable's greatest observed value (maximum) and deducting the least observed value will yield the range (minimum). Limits of variation or potential range: a variety of steel costs; several styles; The size or scope of an action or operation: insight. how far a weapon's projectile can or will travel. The number in a list or set between the lowest and maximum is referred to as a range. Line up all the numbers before locating the region. After that, take away (get rid of) the lowest number from the greatest number. The solution provides the list's range.
The regions where the absolute values are zero are known as the vertex points of an absolute value function.
\(|x + 1| = 0\\x + 1 = 0\\x = -1\)
\(y = |-1 + 1| + 3\\y= 0 + 3\\y = 3\)

Calculate the side lengths a and b to two decimal places
Answer:
E
Step-by-step explanation:
using the Sine rule in Δ ABC
\(\frac{a}{sinA}\) = \(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
where a is the side opposite ∠ A , b opposite ∠ B , c opposite ∠ C
we require to calculate ∠ C
∠ C = 180° - (64 + 85)° = 180° - 149° = 31°
then to find a , using
\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\)
\(\frac{a}{sin64}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
a × sin31° = 9.3 × sin64° ( divide both sides by sin31° )
a = \(\frac{9.3sin64}{sin31}\) ≈ 16.23 ( to 2 decimal places )
then to find b , using
\(\frac{b}{sinB}\) = \(\frac{c}{sinC}\)
\(\frac{b}{sin85}\) = \(\frac{9.3}{sin31}\) ( cross- multiply )
b × sin31° = 9.3 × sin85° ( divide both sides by sin31° )
b = \(\frac{9.3sin85}{sin31}\) ≈ 17.99 ( to 2 decimal places )

The width of a rectangular slab of concrete is 14 m less than the length. The area is 32 m². What are dimensions of rectangle? The length of the slab?
The dimensions of the rectangular slab are 16 meters in length and 2 meters in width.
Let's assume the length of the rectangular slab of concrete is L meters. According to the given information, the width is 14 meters less than the length, so the width would be L - 14 meters.
The formula for the area of a rectangle is A = length × width. In this case, the area is given as 32 m², so we can set up the equation:
32 = L × (L - 14)
Expanding the equation, we get:
32 = L² - 14L
Rearranging the equation, we have:
L² - 14L - 32 = 0
To solve this quadratic equation, we can either factorize it or use the quadratic formula. In this case, it's easier to use the quadratic formula:
L = (-b ± √(b² - 4ac)) / (2a)
Here, a = 1, b = -14, and c = -32. Substituting these values into the formula, we get:
L = (14 ± √((-14)² - 4 × 1 × (-32))) / (2 × 1)
Simplifying further:
L = (14 ± √(196 + 128)) / 2
L = (14 ± √324) / 2
L = (14 ± 18) / 2
Therefore, we have two possible values for L:
L₁ = (14 + 18) / 2 = 16
L₂ = (14 - 18) / 2 = -2
Since the length of the slab cannot be negative, we discard the negative value.
Thus, the length of the rectangular slab is 16 meters. To find the width, we subtract 14 meters from the length:
Width = 16 - 14 = 2 meters
Therefore, the dimensions of the rectangle are 16 meters by 2 meters.

The company also has plans to open a third obstacle course, The Gridiron, where the first three checkpoints will have coordinates A′′(0,−5), B′′(9,−5), and C′′(4,−5). What relationship could this location have to the previous locations? Select all answers that apply.
Answer: It is a reflection of Reflections of You (second location) in the x-axis.
Step-by-step explanation: Based on the given information, the relationship between the new location (The Gridiron) and the previous locations can be determined.
The correct answer is:
It is a reflection of Reflections of You (second location) in the x-axis.
The coordinates of the first three checkpoints of The Gridiron (A''(0,−5), B''(9,−5), and C''(4,−5)) indicate that they have the same y-coordinate (-5) as the corresponding checkpoints in the second location, Reflections of You. However, there is no indication of a reflection in the y-axis or any transformation related to the first location, Transformation Fitness Studios. Therefore, the correct answer is that The Gridiron is a reflection of Reflections of You in the x-axis.
What is the result of isolating x² in the equation below?
(x+1)² + (y-8)² = 9
OA. x²=-y²-2x+16y-56
OB. x² = y² +2x+16y+56
C. x = -² -56
D. * = y² +56
The required result of the identity is \(x^{2} =-y^{2}-2x+16y-56\).
To isolate the algebraic expression given below we need to simplify it and then make \(x^{2}\) the subject of the equation,
For that we must know the identity \((a+b)^{2}=a^{2}+2ab+b^{2}\).
We will break the given equation on the basis of the given identity.
Now, \((x+1)^{2} +(y-8)^{2}=9\\\)
⇒\(x^{2} +2x+1+y^{2}-16y+64=9\\\)
⇒ \(x^{2} =-y^{2}-2x+16y-56\)
So, the required result of isolating the above given equation is as above.
The correct answer is option B.

Step-by-step explanation:
Joey is flying his Cesna due Northwest at 188mph. Unfortunately, a wind traveling.
60mph due 150 bearing. Find Joey's actual Speed and direction.
Joey's actual speed is 143.59 mph, and his actual direction is slightly west of northwest.
Given that Joey's aircraft speed: 188 mph
Wind speed: 60 mph
Wind direction: 150 degrees (measured clockwise from due north)
We can consider the wind as a vector, which has both magnitude (speed) and direction.
The wind vector can be represented as follows:
Wind vector = 60 mph at 150 degrees
We convert the wind direction from degrees to a compass bearing.
Since 150 degrees is measured clockwise from due north, the compass bearing is 360 degrees - 150 degrees = 210 degrees.
Joey's aircraft speed vector = 188 mph at 0 degrees (due northwest)
Wind vector = 60 mph at 210 degrees
To find the resulting velocity vector, we add these two vectors together. This can be done using vector addition.
Converting the wind vector into its x and y components:
Wind vector (x component) = 60 mph × cos(210 degrees)
= -48.98 mph (negative because it opposes the aircraft's motion)
Wind vector (y component) = 60 mph×sin(210 degrees)
= -31.18 mph (negative because it opposes the aircraft's motion)
Now, we can add the x and y components of the two vectors to find the resulting velocity vector:
Resulting velocity (x component) = 188 mph + (-48.98 mph) = 139.02 mph
Resulting velocity (y component) = 0 mph + (-31.18 mph) = -31.18 mph
Magnitude (speed) = √((139.02 mph)² + (-31.18 mph)²)
= 143.59 mph
Direction = arctan((-31.18 mph) / 139.02 mph)
= -12.80 degrees
The magnitude of the resulting velocity vector represents Joey's actual speed, which is approximately 143.59 mph.
The direction is given as -12.80 degrees, which indicates the deviation from the original northwest direction.

The manager at Mugg & Bean has been recording the behaviour of their customers with regards to coffee and muffins. The manager established that that the probability that a customer will buy a cup of coffee is 0.8. A customer buys a muffin 50% of the time when a cup of coffee is bought. but only 10% of the time when a cup of coffee is not bought. What is the probability of buying a muffin, when first buying a cup of coffee?
Solution:
Let M represent the muffin,
let C represent the coffee.
Given that the probability that a customer will buy a cup of coffee is 0.8, this implies that
\(Pr(C)=0.8\)A customer buys a muffin 50% of the time when a cup of coffee is bought. This implies that
