Answer:
3-Equalateral
Step-by-step explanation:
All the sides are all equal, which basically eliminates isosceles, isosceles acute, and scalene, therefore the answer is Equalateral.
F(x) = 2x + 1 when x <= -5
Now -10 is less than -5 so we plug x = -10 into 2x +1:-
f(-10) = 2(-10) + 1 = -19 answer
Now f(x) = x^2 when -5< x < 5
x =2 is within this range so f(2) = 2^2 = 4 answer
You can calculate the other 3 values by a similar method
The relationship between the trigonometric ratios are cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>The relationship between the trigonometric ratios</h3>
The given parameters are:
- Scale factor of dilation, k = 2
- cos(X) = 2.5/5/59
Since the transformation is a dilation, it means that both triangles are similar.
So, we have:
cos(X) = cos(A), cos(Y) = cos(C) and cos(Z) = cos(B)
<h3>The segments AC and AB. </h3>
In (a), we have:
Both triangles are similar.
This means that the corresponding points are:
X and A
Y and C
Z and B
So, we have:
AC = 2 * XY
AB = 2 * XZ

This type of situation applies first order type of equation. In this case, the equation is ln( A0/A1) = kt. A is the number of bacteria cultured. A0 is equal to 150. when A1 is 300, t is 20 minutes. that is ln (150/300) = k *20 the other condition is represented by ln (A0/1200) = 60k. k is equal to -0.0347. hence the first order equation is equal to ln (150/A1) = -0.0347 t
