Answer:
300mb
Step-by-step explanation:
We can read the atmospheric pressure at an altitude of 22 kilometers can be read by tracing directly from the graph.
22 kilometers is half way between 20 kilometers and 24 kilometers on the vertical axis.
The reading is shown in the attachment.
From the reading the atmospheric pressure is about 300mb
The correct answer is A
The vertex form of the function is y = (x + 8)² - 71
The vertex is (-8 , -71)
Step-by-step explanation:
The vertex form of the quadratic equation y = ax² + bx + c is
y = a(x - h)² + k, where
- (h , k) are the coordinates of the vertex point
- a, b, c are constant where a is the leading coefficient of the function (coefficient of x²) , b is the coefficient of x and c is the y-intercept
- k is the value of y when x = h
∵ y = x² + 16x - 7
∵ y = ax² + bx + c
∴ a = 1 , b = 16 , c = -7
∵
∴
∴ h = -8
To find k substitute y by k and x by -8 in the equation above
∵ k is the value of y when x = h
∵ h = -8
∴ k = (-8)² + 16(-8) - 7 = -71
∵ The vertex form of the quadratic equation is y = a(x - h)² + k
∵ a = 1 , h = -8 , k = -71
∴ y = (1)(x - (-8))² + (-71)
∴ y = (x + 8)² - 71
∵ (h , k) are the coordinates of the vertex point
∵ h = -8 and k = -71
∴ The vertex is (-8 , -71)
The vertex form of the function is y = (x + 8)² - 71
The vertex is (-8 , -71)

Answer:
3
Step-by-step explanation:
The opposite of -3 is 3.
The length of the door frame for the model car is 12 units and point M is the midpoint which makes AM to 6 units.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram attached:
AE = 12
AM = ME = 12/2 = 6 (definition of midpoint)
The length of the door frame for the model car is 12 units and point M is the midpoint which makes AM to 6 units.
