The measurement of an angle is 40°, and the length of a line segment is 8 centimeters.
Tresset [83]
1
a rhombus is defined as having 4 equal sides so if the measurement is 8 cm all sides will be 8 cm. a rhombus is a parallelogram so if one angle value is defined then the opposite angle is also 40 and the consecutive angles are equal to 140 degrees because consecutive angles in a parallelogram are congruent.

natalie found a tennis ball outside a tennis court. she picked up the ball and threw it over the 12 foot fence into the court. t

The equation that gives the height is h(t) = - 16t^2 + 18t + 5, which is a parabola.


You cand find the maximum height from the vertex of the parabola.


Let's find the vertex. I will complete squares:

Start by extractin common factor -16:

-16t^2 + 18t + 5 = -16 [t^2 - (18/16) t - 5/16]


I will work with the expression inside the square brackets.

t^2 - (18/16)t - 5/16 = t^2 - (9/8) t - 5/16 =


Completing squares: (t - 9/16)^2 - (9 / 16 )^2 - 5/16

(t - 9/16)^2 - 81/ 256 - 5/16 = (t -9/16)^2 - 161/256


Now, include add include the factor -16[ (t- 9/16)^2 + 161/256 ] =

= -16 (t - 9/16)^2 + 161/16

That means that the vertex is 9/16, 161/16

So, the maximum height is 161 / 16 = 10,06, which is lower than the fence.


Answer: She will not make it over the fence.
