Answer:
4.8
Step-by-step explanation:
(7, 7.6) (7, 2.8)
√(x2 - x1)² + (y2 - y1)²
√(7 - 7)² + (2.8 - 7.6)²
√(0)² + (-4.8)²
√(23.04)
= 4.8
Answer:
D
Step-by-step explanation:
a "function" gives every x value exactly one y value.
A, B and C all have 2 or more y values for an x value.
use e.g. a pen and place it vertically (straight top-down, parallel to the y-axis) on the graphs.
how often does the pen intersect the function curve ?
that is what I am talking about.
if it is more than once, than the x value (the point on the x-axis), where you put your pen, has more than 1 y values.
and that is then not a function.
only D is a function. the pen intersects with the function curve only once, no matter where you put the vertical pen.
Answer:
The inverse is ±sqrt(x/6)
Step-by-step explanation:
Let y = 6x^2
To find the inverse, exchange x and y and then solve for y
Exchange x and y
x = 6y^2
Solve for y
Divide each side by 6
x/6 = 6y^2 /6
x/6 = y^2
Take the square root of each side
±sqrt(x/6) = sqrt(y^2)
±sqrt(x/6) =y
The inverse is ±sqrt(x/6)
10-6= 4
6x10=60
therefore the answer is 10 and 6.
Answer:
the perimeter of a square = 28 feet.
the area of a square = 49 ft²
Step-by-step explanation:
given:
side length of a square = 7 feet.
find:
perimeter (P) of a square
area (A) of a square
<u>Perimeter of a square = 4s</u>
P = 4(7)
P = 28 feet.
<u>area of a square = s²</u>
A = 7²
A = 49 ft²
therefore,
the perimeter of a square = 28 feet.
the area of a square = 49 ft²
