Answer:
X=3
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
See below
Discussion:
This picture appears to be an application of the Pythagorean theorem. That is, the sum of the squares of the legs equals the square of he hypotenuse. Let's check this out.
Does
(leg1)^2 + (leg2)^2 = (hypotenuse)^2
5^2 + 5^2 = (5 sqrt(2)) ^ 2 ? => number from diagram
25 + 25 = 5 * 5 * (sqrt(2) ) ^ 2 => as (sqrt(2)) ^ 2 = 2
25 + 25 = 5*5*2 = 50 =>
50 = 50.
Indeed.
Note: this is an isosceles triangle as the base angles equal 45 degrees. It illustrates that in an isosceles triangle the length of the hypotenuse is the length of either leg times the sqrt(2)
Thank you,
MrB
Answer and explanation:
V originally equals u + at, but when you plug in u, a, and t you get a number answer.
u = 2
a = 15
t = 1/5
Rewrite the expression with the numbers plugged in.
V = (2) + (15)(1/5) <em>Multiply 15 by 1/5</em>
V = 2 + 3 <em>Add 2 and 3 together</em>
V = 5
<h2><u>So V would equal 5</u></h2>
The answer would be -26
-(-4)^2-10
-4 squared is 16 times -1 is -16
-16-10
-26
