The answer is D, it’s a lot to explain just trust me.
#sol1
a1=1×4-1=3
a2=2×4-1=7
a3=3×4-1=11
a4=4×4-1=15
a5=5×5-1=19
#sol2
f(1)=1×4-1=3,
f(n+1)=f(n)+4,
so .... you know.
Is there a graph?
If you have more info you will get the best answer.
I=prt. I=375x .035x 4. I= 8.85x4. I=35.42
<u>Given</u>:
The triangle ABC is a right angled triangle.
The length of AB is 10 m
The length of BC is a.
The measure of angle A is 38°
We need to determine the value of a.
<u>Value of a:</u>
The value of a can be determined using the formula,
where , and
Substituting these values, we get;
Substituting BC = a and AB = 10, we get;
Multiplying both sides of the equation by 10, we get;
Thus, the value of a is 6.157 m
