What is the length of AB?

Tresset [83]

Answer:

angle B'CA'= angle BCA..... (common angle)

angle B'A'C = angle BAC.....(corresponding angels)

therefore,

ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)

therefore,

B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)

now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9

5 / BA. = 6 / 9

therefore, 5 / BA. = 2 / 3

$ba \: = \frac{5 \times 3}{2 } \\ = \frac{15}{2} \\ = 7.5$

Answer : AB = 7.5 units

a population of insects increases at a rate of 1.5% per day about how long will it take to double A)2.5 days b) 5.0 days c) 46.6

ANTONII [103]

We can use population formula

$P(t)=P_0(1+r)^{t}$

we are given

interest rate is 1.5% per day

so,

$r=0.015$

now, we can plug values

$P(t)=P_0(1+0.015)^{t}$

$P(t)=P_0(1.015)^{t}$

we are given

P(t)=2Po

we can plug it

$2P_0=P_0(1.015)^{t}$

we can solve for t

$2=(1.015)^{t}$

$t=46.55$

so,

number of days is 46.5..........Answer
