A line segment has an endpoint at (-4,8) and a midpoint

Mathematics

grin007 [14]2 years ago
7 0

Answer:

The coordinates of the midpoints are the average coordinates of the endpoints. Suppose (x1,y1) and (x2,y2) are the endpoints and (xm,ym) is the midpoint, we have xm=x1+x22 and ym=y1+y22 . Therefore, 2xm=x1+x2 and 2ym=y1+y2 . From there, we should be able to figure the other endpoint out given an endpoint and the midpoint.

Estimate the slope of the tangent line of the function y(t)=\sqrt{(3t+1} at the point t=2.
Korvikt [17]

Answer: 0.567

Step-by-step explanation:

y(t)=\sqrt{3t+1} \\\\y'(t)=\dfrac{3}{2\sqrt{3t+1} } \\\\y'(2)=\dfrac{3}{2\sqrt{3*2+1} } =\dfrac{3\sqrt{7} }{14} =0,56694670951384084082177480435127\approx{0.567}

Explain please and tell me how to do it ?
SCORPION-xisa [38]

The trick to calculating the area here is to subdivide the diagram into smaller parts. For example, there's a 3 cm-by-3cm square. The rectangle is 4 cm by 8 cm.. The triangle has a base of 5 cm and a height of 3 cm.

Total area = area of square + area of rectangle + area of triangle

= 9 cm^2 + 32 cm^2 + (1/2)(5 cm)(3 cm)

= (9 + 32 + 7.5) cm^2

= 48.5 cm^2 (total area of figure)

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of the function y = 4x2 – 8x – 3.
Schach [20]
Axis of symmerty from form
ax²+bx+c is -b/2a
the axis of symetry is the x value of the vertex so just put the axis of symetry for x an evaluate


4x²-8x-3
-b/2a=-(-8)/(2*4)=8/8=1

input for x
4(1)²-8(1)-3=4-8-3=-7

(1,-7) is vertex
