2 answers:
<h2>Answer:</h2>
The length of EF in the given right triangle is:
Option: B 24
<h2>Step-by-step explanation:</h2>We are given a right triangle EFD with base DF=a=7 units.
Height EF=b
and Hypotenuse of the triangle ED=c=25 UNITS.
We know that in a right angled triangle we can apply Pythagorean Theorem.
According to Pythagorean Theorem we have:
on taking square root on both side we get:
But as side of a triangle can't be negative.
Hence, b= 24 units.

Answer: Choice D
This basically says "the nth term is found by computing math, aka evaluating some function, based on the (n-1)th term".
As an example, we could have a function that simply squares the input
Let's say we started at 5. It squares to 25 which in turns squares to 625, and so on. Each new term is based on the old term. Namely, we squared the old n-1 term to get the new nth term.
Answer:
The sum of the given series is 1023
Step-by-step explanation:
Geometric series states that a series in which a constant ratio is obtained by multiplying the previous term.
Sum of the geometric series is given by:
where a is the first term and n is the number of term.
Given the series:
This is a geometric series with common ratio(r) = 2
We have to find the sum of the series for 10th term.
⇒ n = 10 and a = 1
then;
Therefore, the sum of the given series is 1023
