Answer: 315 cookies
Step-by-step explanation: 73+242 = 315
#13:
s² = 144
√(s²) = √144
|s| = 12
s = -12 OR s = 12
--------------------
#15 (not sure what letter you used so I went with 'g')
(g-6)² = 25
√[(g-6)²] = √25
|g-6| = 5
g - 6 = -5 OR g - 6 = 5
g = 1 OR g = 11
Answer:
the third one and the last one is correct
Step-by-step explanation:
we already know the second one is wrong because of it's set up.
just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)
Answer:
I need to know what question 1 is because we cant figure it out if you don't have 1)
Step-by-step explanation:
Postive
<span>y = tan^−1(x2/4)</span>
tan(y) = x2/4
sec2(y) = x/2
y′ = xcos^2(y)/2
<span>cos^2(y) = <span>16x2+16</span></span>
<span>y′ = <span>8x/(<span>x2+16)
let u be x2+16
du is 2x dx
dy = 4 du / u
y = 4 ln (</span></span></span>x2 <span>+ 16)
y at x =0 = </span> 4 ln (<span>16) = 11.09</span>
