Answer:
Your answer would be C
Step-by-step explanation:
18 inches was the height of the baby when they were born since it isn't y which would be the current height of the baby now in months that tells me months have passed which includes x is the age of the baby in months.
Step-by-step explanation:
the answer in the image
First find constant for inversely proportional k(constant)=12×3=36 so in next 36=y4..y=36/4=9
Given the sides 11,13,19, to calculate for the smallest angle using cosine rule, i.e;
a^2=b^2+c^2-2bc cos (A)
we shall proceed as follows;
The smallest angle is always opposite to the shortest side; Since 11 is our shortest side, the smallest angle is the angle opposite to this side. Thus;
let a=11 and our smallest angle be A
thus
11^2=13^2+19^2-2*13*19 Cos A
121=169+361-494 Cos A
121=530-494 Cos A
-409=-494 Cos A
dividing through by -494 we get;
Cos A=0.8279
thus
A=Cos(-1) 0.8279
A=34.113°≈34°
The answer is A=34°
Answer:
Possible coordinate of F are (10,5) and (6,11)
Step-by-step explanation:
Coordinates A (1, 2), B (3, 2) and C (3, 5) are connected to form ΔABC
First we plot the points on coordinate plane and then draw triangle ABC. Please see the attachment for figure.
If ΔDFE is similar to ΔABC then their corresponding sides are in proportional.
Using distance formula, 
We can see ABC is right angle triangle. So, DEF must be right angle triangle because ΔDFE ~ ΔABC
Thus, Possible coordinate of F are (10,5) and (6,11)
