Answer:
1
Step-by-step explanation:
( 50 / 5² )² ÷ 4 (by PEDMAS, do the terms inside the parentheses first)
= [ (5 · 10) / (5 · 5) ]² ÷ 4 (the 5's cancel out in the numerator and denominator)
= [ (10) / (5) ]² ÷ 4
= [ 2 ] ² ÷ 4
= 4 ÷ 4
= 1
Hope this helps
Answer:
x = (5,3)
Step-by-step explanation:
the quadratic formula is x =( -b±√(b^2-4ac))/2a
to solve for x, a=1, b=-8,c=15
x =( -(-8)±√((-8)^2-4*1*15))/2(1)
x=8 ± √(64-60))/2(1)
x=(8 ± √(4)) / 2
x=(8 ± 2) / 2
solve with '+'
x=(8 + 2) / 2 = 10/5 = 5
solve with '-'
x=(8 - 2) / 2 = 6/2 = 3
x = (5,3)
see the attached figure to better understand the problem
we have that
Step 1
<u>Find the value of AC</u>
we know that
in the right triangle ABC
substitute the values in the formula
Step 2
<u>Find the value of BC</u>
we know that
in the right triangle ABC
Applying the Pythagorean Theorem
substitute the values
Step 3
<u>Find the value of BD</u>
we know that
in the right triangle BCD
Applying the Pythagorean Theorem
substitute the values
therefore
<u>the answer is</u>
the length of BD is 11.93 units
Answer:
ok
Step-by-step explanation:
ty
i guess i got the answer ...
well..... four times a number b = 4×b = 4b
one more than is +1
and this = 17
now we need to put it all together and forma an equation .... so .. it will be
4b + 1 = 17
4b = 17 - 1
4b = 16
b = 16/4
∴ b = 4
