Answer:
-18
Explanation:
a - b
a = -7
b = 11
Insert -7 for 'a' and 11 for 'b'
-7 - 11
= -18
So here is the answer to the given equation above.
To find the answer, we can just factor this one.
<span>(2sinθ+1)(sinθ−1)=0</span><span>sinθ = <span><span>−1/</span>2</span>→θ = <span>{<span><span><span>−π/</span>6 </span>+ 2kπ, <span><span>7π/</span>6 </span>+ 2kπ</span>}</span></span><span><span>sinθ=1→θ=<span>{<span><span>π/2 </span>+ 2kπ</span>}
Hope this answers your question. Let me know if you need more help next time. Have a great day!</span></span></span>
Idk this cause my teacher. Any teach
L = 2W
P = 2L + 2W
Plug 2W in for L.
54 = 2(2W) + 2W
54 = 4W + 2W
54 = 6W
Divide both sides by 6
W = 9
L = 2* 9
L = 18
A = L * W
A = 9 * 18
A = 162 units^2
Answer:
20
Step-by-step explanation:
To calculate the sum of the residuals, subtract the predicted sales from the actual sales in the table below.
Actual sales 55 150 325 510 780 990
Predicted sales 40 150 300 500 800 1,000
This will show the change between them. Add each residual to find the sum.
55 - 40 = 15
150 - 150 = 0
325 - 300 = 25
510 - 500 = 10
780 - 800 = -20
990 - 1000 = -10
These add up to be 15 + 25+ 10 +-20 +-10 = 20
