Answer:
y²/25+x²/4=1
Step-by-step explanation:
The equation for an ellipse is either categorized as
x²/c² + y²/d² = 1 . In such an equation, the vertices on the x axis are categorized by (±c,0) and the vertices on the y axis are (0, ±d)
In the ellipse shown, the vertices/endpoints on the x axis are (-2,0) and (2,0). This means that c is equal to 2. Similarly, on the y axis, the endpoints are (5,0) and (-5,0), so d=5.
Our equation is therefore x²/2²+y²/5²=1 = x²/4+y²/25=1
Our answer is therefore the fourth option, or
y²/25+x²/4=1
Answer:
Step-by-step explanation:
The question is asking you to graph the equations.
The equations are in slope intercept form so y=mx+b
M is the slope and b is the y-intercept
First draw the y & x axis and label/number them
The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis
The slope is 2/5 and you use rise/run to continue the slope.
you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)
For the second equation, you have to turn it into slope intercept form.
You should get y=2/3x+3
You graph this equation the same as you did the first one.
Adjacent angles-
2 angles that share a common vertex, a common side and no common interior points.
The answer is ADJACENT ANGLE

Answer:
8 seconds
Step-by-step explanation:
The length of the water slide is 376 feet and Lainey is sliding down at a rate of 47 feet per second. That is her speed.
Speed is given as distance divided by time or the time rate of displacement.
Therefore, time is:
Time = distance / speed
Therefore, the time it will take Lainey to get from the top to the bottom is:
Time = 376 / 47 = 8 seconds
It will take her 8 seconds to get from the top to the bottom.
