If the vertex of the graph of y = −1(x − 2)2 + 3 is (a,b) what is the value of b?
Answer:
the value of b is 3.
Step-by-step explanation:
The vertex of the graph of a parabola in the form y = a(x - h)^2 + k is given by (h, k), where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.
So in this case, the vertex of the graph of y = -1(x - 2)^2 + 3 is (2, 3), and the value of b is 3.
Answer:
b=3
Step-by-step explanation:
[tex]y=a(x-h)^2+k\\y=-1(x-2)^2+3[/tex]
If we compare the vertex-form equation of a parabola to our given function, we can see the vertex is [tex](2,3)[/tex], which means that b=3.
Which graph matches the equation y+6=3/4 (x+4)?
Answer: The equation y + 6 = 3/4 (x + 4) can be solved for y to find the corresponding graph:
First, isolate x by subtracting 4 from both sides:
y + 6 - 6 = 3/4 (x + 4) - 6
y = -6 + 3/4 (x + 4)
Next, isolate y by dividing both sides by 3/4:
y = -6 + 3/4 (x + 4) ÷ (3/4)
y = -6 + (x + 4)
y = x - 2 + 10
This equation represents a line with a slope of 1 and a y-intercept of 10 - 2 = 8. The graph of this line is a line that passes through the points (0, 8) and (1, 9).

At Santorini's Shakes, a regular milkshake costs $3.50. A larger milkshake can be purchased for an additional $0.40 per ounce above the regular size.
If x represents the number of ounces above the regular size, which inequality shows how much can be added to the regular size for a milkshake that costs under $5.00?
Answer:
5=0.40x+3.50
He can get 3 extra ounces
Step-by-step explanation:
5.00-3.50=1.50 so an extra $1.50 to spend on extra ounces
1.50/0.40=3
0.40(3)+3.50= $4.70
So the most ounces he can get is 3
He will have $0.30 left
What is the value of 350f in c?
The temperature 350°F is equivalent to 176.667°C. This is because the temperature in Fahrenheit can be converted to Celsius using the formula, °C = (°F - 32) / 1.8. Using this formula, 350°F - 32 = 318 and 318/1.8 = 176.667°C.
The relationship between Fahrenheit and Celsius scales is a linear one, meaning that for every degree increase in Fahrenheit, there is a corresponding increase of 1.8 degrees in Celsius. This means that if the temperature increases from 350°F to 351°F, then the corresponding temperature in Celsius would increase from 176.667°C to 178.472°C. The same formula can be used to convert Celsius to Fahrenheit, with the formula °F = (°C x 1.8) + 32. In this case, 176.667°C x 1.8 = 319.2 and 319.2 + 32 = 351.2°F, which is a close approximation of the original temperature of 350°F..

The position of a ball after it is thrown is modeled with the
function f(x) = -2(x - 1)² + 7 in vertex form, where y is
the height, in feet, above the ground and x is the horizontal
distance, in feet, of the ball from where it is thrown.
A. Write the function in standard form.
B. What is the height of the ball when it is thrown?
C. What is the horizontal distance from the point where the ball is thrown to the highest point that the ball reaches?
(a) The function in standard form is f(x) = -2x² + 4x + 5.
(b) The height of the ball when it is thrown is 5 feet.
(c) The horizontal distance from the point where the ball is thrown to the highest point that the ball reaches is 1 foot.
What is the function of ball's motion?
To write the function in standard form, we need to expand the square and simplify the expression:
f(x) = -2(x - 1)² + 7
f(x) = -2(x² - 2x + 1) + 7
f(x) = -2x² + 4x - 2 + 7
f(x) = -2x² + 4x + 5
B. The height of the ball when it is thrown is the y-intercept of the function, which occurs when x = 0. So we can find the height by plugging x = 0 into the function:
f(0) = -2(0)² + 4(0) + 5
f(0) = 5
C. The highest point that the ball reaches is the vertex of the parabola, which occurs at x = 1 (from the given vertex form). To find the height of this point, we can plug x = 1 into the vertex form of the function:
f(1) = -2(1 - 1)² + 7
f(1) = -2(0) + 7
f(1) = 7
Therefore, the highest point that the ball reaches is 7 feet above the ground. The horizontal distance from the point where the ball is thrown to this point is the distance between the point (0,5) and the vertex (1,7), which is 1 unit.

What is the slope and y-intercept of the linear function?
The slope is ____ and the y-intercept is ___.
Answer:
The slope is 30, and the y-intercept is 75.
Step-by-step explanation:
Use two points from the table, and find the equation of a line given two points.
Point 1: (1, 105)
Point 2: (3, 165)
y = mx + b

An airplane takes 7 hours to fly 2800 kilometers against the wind. The return trip with the wind takes only 4 hours. What is the speed, in kilometers per hour, of the airplane in still air?
Answer: Let's call the speed of the airplane in still air "x".
Since the airplane takes 7 hours to fly 2800 kilometers against the wind, its speed against the wind is 2800/7 = 400 km/hr.
Since the return trip with the wind takes only 4 hours, the speed of the wind must be 400 - x.
The total speed of the airplane on the return trip is x + (400 - x) = 400 km/hr.
So, we have:
400 = x + (400 - x)
Expanding the right side:
400 = 400
Therefore, x = 400 km/hr, which is the speed of the airplane in still air.

There were 65 more adults than students who bought tickets to the concert.
How to find the number of hamburgers sold on Saturday?Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.
Let the number of discounted student tickets sold be x.
Then the number of adult tickets sold is 10 more than twice x, which is 2x+10.
The total number of tickets sold is the sum of the student and adult tickets, which is x + (2x+10) = 3x+10.
We know that the total number of tickets sold is 175, so:
3x+10 = 175
Subtracting 10 from both sides gives:
3x = 165
Dividing by 3 gives:
x = 55
Thus, the number of discounted student tickets sold is 55, and the number of adult tickets sold is:
2x+10 = 2(55) + 10 = 120.
The number of adults who bought tickets is 120, and the number of students who bought tickets is 55.
difference = 120 - 55 = 65
Therefore, there were 65 more adults than students who bought tickets to the concert.

When the car reaches point (A), it has a speed of 25 m/s. If the breaks are applied, its speed is reduced by at= (-1/4t^1/2)m/s^2. Determine the magnitude of acceleration of the car just before it reaches point C
The magnitude of acceleration of the car just before it reaches point C is -0.79 m/s^2.
About magnitude of accelerationThe magnitude of acceleration of the car just before it reaches point C can be calculated using the given formula for acceleration, at= (-1/4t^1/2)m/s^2.
First, we need to determine the time it takes for the car to travel from point A to point C.
Since the speed of the car at point A is 25 m/s, and the speed at point C is 0 m/s, we can use the formula for speed, v=at, to find the time it takes for the car to travel from point A to point C.
Rearranging the formula, we get t=v/a.
Substituting the values for speed and acceleration, we get t=25/(-1/4t^1/2).
Solving for t, we get t^3/2 = -100.
Taking the square root of both sides, we get t=10 seconds.
Now, we can substitute the value of t back into the formula for acceleration to find the magnitude of acceleration just before the car reaches point C.
at= (-1/4t^1/2)m/s^2
= (-1/4)(10^1/2)m/s^2

The missing angle measures are:
m2F = 50 degrees
m2H = 125 degrees
m2G = 5 degrees
m2C = 158 degrees
How to find the missing angle measures?
Since triangle ABC is similar to triangle FGH, the ratios of their corresponding angles are equal. Let's call the missing angles m2F, m2H, m2G, and m2C.
From the given information, we have:
m2F / mLA = m2H / mzB
So, we can find m2H by cross-multiplying and solving for m2H:
m2H = (mzB * m2F) / mLA
Since we don't know m2F, we can use the fact that the sum of the angles in a triangle is 180 degrees:
m2F + m2H + 75 = 180
So,
m2F + ((mzB * m2F) / mLA) + 75 = 180
Expanding and solving for m2F:
m2F + (75 * m2F / 22) + 75 = 180
(22 + 75) * m2F / 22 + 75 = 180
97 * m2F / 22 + 75 = 180
97 * m2F / 22 = 180 - 75
97 * m2F / 22 = 105
m2F = 105 * 22 / 97 = 50
So, the missing angle measures are:
m2F = 50 degrees
m2H = (75 * 50) / 22 = 125 degrees
m2G = 180 - 50 - 125 = 5 degrees
m2C = 180 - 22 = 158 degrees

Using the formula to convert Fahrenheit to Celsius, we get that 100.8°F is 38.22°C.
To convert 100.8°F to °C, we can use the formula:
°C = (°F - 32) x 5/9
Plugging in the value of 100.8°F, we get:
°C = (100.8 - 32) x 5/9
°C = 68.8 x 5/9
°C = 38.22
Therefore, 100.8°F is equal to 38.22°C.
This formula is used to convert temperatures between the Fahrenheit and Celsius scales. It involves subtracting 32 from the Fahrenheit temperature and then multiplying by 5/9 to obtain the equivalent Celsius temperature. The resulting Celsius temperature is then rounded to the nearest tenth. It's important to note that Fahrenheit and Celsius are two different temperature scales, where 0°C is equal to 32°F, and 100°C is equal to 212°F. The Celsius scale is based on the freezing and boiling points of water, whereas the Fahrenheit scale is based on the freezing and boiling points of a solution of salt and water. Knowing how to convert between these two scales can be useful in a variety of settings, including cooking, weather reporting, and scientific research.

x^-5y^3 negative exponents
The solution is x^-5y^3 = y^3/x^5.
What is an exponent in math?An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
here, we have,
given that,
x^-5×y^3
[ as, the power of x is negative 5, so, we make it positive 5 by dividing}
=1/x^5 * y^3
=y^3/x^5
Hence, The solution is x^-5y^3 = y^3/x^5.
