Hello,
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33
==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)
or t=(17+√33)/32=0.710767 (s)≈0.71 (s)
Answer:
Step-by-step explanation:
3x+5+4x+8=69
7x+5+8=69
7x+13=69
-13 -13
7x=56
7x/7=56/7
x=8
3x+5
3(8)+5
24+5

JT=29
A: (x^a) / (x^a) = x^(a - a) = x^0
B: Anything divided by itself is 1, so x^a / x^a = 1.
C: If x^a / x^a = x^0 from Part A and x^a / x^a = 1 from Part B, then x^0 = 1.
Reflect: 1. To complete Part A, we used the quotient rule for exponents.
Hope this helps!
The researchers used data from 10 trials so they could compare each trial or use the information in all, its better to use more than one so you can compare and see the difference.
We have that
-7x-60=x²<span>+10x
</span>x²+10x+7x=-60
x²+17x=-60
(x²+17x+8.5²)=-60+8.5²
(x+8.5)²=12.25
(+/-)(x+8.5)=√12.25--------> (+/-)(x+8.5)=3.5
(+)(x+8.5)=3.5------> x=-5
(-)(x+8.5)=3.5------> x=-12
therefore
(x+5)*(x+12) is equivalent to -------> -7x-60=x²+10x
the answer is
(x+5)*(x+12)
