Step-by-step explanation:
your formula is x=-b+- square root b squared -4(a)(c) all over 2(a) just plug it in and solve. Please give me the brailiest answer?
:) Hoped this helped!!! Have a good day!!! <3
Answer:
Step-by-step explanation:
Explicit Arithmetic Formula: 
a₁ is 1st term in sequence
<em>d</em> is common difference
<em>n</em> is term number
Step 1: Find <em>d</em>
d = 8 - 2 = 6
Step 2: Plug in variables into formula
Answer:
7) is 625
8) 169
9) 1.44
10) 180??
11) 1000000
12) 3430
hopefully these are right
Step-by-step explanation:
18 = 10 + 2k
move 10 to the other side
sign changes from +10 to -10
18-10=10-10+2k
18-10= 2k
8= 2k
divide by 2 to get k by itself
8/2= 2k/2
Cross out 2 and 2 , divide by 2 and then becomes 1*1*k= k
k=8/2
Answer: k= 4
Answer: 113.0 ft (bottom right corner)
=====================================
Explanation:
The triangle has a horizontal leg of 220 ft and a vertical leg of x ft. We'll use the tangent rule to connect the opposite side and adjacent side
opposite side = x
adjacent side = 220
this is with the reference angle shown in the diagram
So,
tan(angle) = opposite/adjacent
tan(26) = x/220
220*tan(26) = x
x = 220*tan(26)
x = 107.301169 ... see note below
x = 107.3
Now that we know the approximate value of x, we add on 5.7 to get
x+5.7 = 107.3+5.7 = 113.0
note: make sure your calculator is in degree mode. The value is approximate to 6 decimal places
