What is an isosceles triangle?Therefore, an isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg). An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal.
Triangle XYZ is isosceles and Angle Y measures a°.
The lengths of sides Y X and Z X are congruent.
An isosceles triangle has two sides equal and two angles equal. It is given in the problem that ∠Y is equal to a². We can solve for the remaining angles, and the solution is shown below:
180°=∠X+∠Y+∠Z
180°=∠X+a° +∠Z
180°-a°-∠Z=∠X
If ∠Z is the same with ∠Y, then ∠X is equal to 180°-2a°. The measures of angle Y and Z = a.
Therefore, the correct option is d, 180 - 2a.

An object moves along a straight line so that at any time t, 0≤t≤9, its position is given by x(t)=7+6t−t2. For what value of t is the object at rest?.
Answers
We will see that for t = 3 seconds the object will be at rest.
When does an object is at rest?
We say that something is at rest if its velocity is equal to zero.
Here we know that the position equation of the object is:
x(t) = 7 + 6*t - t^2
To get the velocity, we need to differentiate with respect to the time, using the rule:
[tex]f(x) = a*x^n\\\\f'(x) = n*a*x^{n-1}[/tex]
We will get:
v(t) = 6 - 2*t
Now we just need to find the value of t such that the above equation is equal to zero:
0 = 6 - 2*t
2*t = 6
t = 6/2 = 3
Then for t = 3 seconds, the object will be at rest.

Explanation:
An object being at rest indicates the velocity is 0. Set the derivative of the equation equal to zero. (0=6-2t) Subtract 6 from both sides (-6=-2t) and then divide by negative 2 to get t=3, meaning the object is at rest at

In a set of experiments, a student research team used labeled thymidine nucleotides and introduced these into a culture of dividing human cells. Which of the following questions might be answered by such a method?.
Answers
Answer:
The four nitrogenous bases that are present in DNA are adenine, guanine, thymine and cytosine. These nucleotides can be radiolabelled before the new DNA forms and the composition of specific nucleotide of DNA can be estimated.
During the experiment, research team found that the incorporation of radioactive nucleotides composition increase after the introduction of pathogen in the culture. This means that the cell starts producing more number of cell to fight against the pathogen. The infection of pathogen is mainly responsible for the division of lymphocytes more rapidly.
