Answer:
C. 50
Step-by-step explanation:
The triangles are proportional and that is why you can find the scale factor. Set up a proportion (equivalent fractions). Set the proportion up with the corresponding sides together on thee top or the bottom of the proportion.
<u>65 </u> = <u> 91</u>
x 70
91x = 65 * 70
<u>91x</u> = <u>4550</u>
91 91
x = 50
Answer:
C = 50p +900
Step-by-step explanation:
Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).
Equation: C = 900 +50p
__
The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.
Answer:
We readily separate the variables and integrate:
∫dP/P=∫(k+bcos2
t)dt
ln P=kt+(b/2)*sin2t+ln C
Clearly C = Po, so we find that P(t) = Poexp(kt + (b/2)* sin 2t). The 271- curve with the typical numerical values P_o = 100, k = 0.03, and b = 0.06. It oscillates about the curve which represents natural growth with P_o and k = 0.03. We see that the two agree at the end of each full year.

Answer:
Q) (-2, 2)
V) (2, 2)
Step-by-step explanation:
This ratio is 6:7 which is a total of 13 parts so 260/13 is 20 so each part is 20 which makes this into the ration 120: 140 meaning bob invested 140 and ellen invested 120
