Answer:

A, D

Step-by-step explanation:

The figure looks symmetrical, but their is no given information indicating it actually is symmetrical. Thus we can't make any statements about the segment lengths. Nor is there any indication that any of the arc lengths are identical.

If we rule out statements about segments and arcs, that only leaves statements about angles. As it happens both of those are true: inscribed angles that intercept the same arc are congruent.

The true statements are ...

A: ∠CAD≅∠CBD

D: ∠ACB≅∠ADB

Arturiano [62]

Answer:

Jane

Step-by-step explanation:

Since Amil has twice the size of Jane's garden, he would have more space and his 28 watermelons would not be as close and dense. Jane has 22 watermelons and her garden is half the size. Her 22 watermelons would be more dense and close to each other in a garden half the size of the neighbors.

The height of a flare fired from a 32-foot high platform can be modeled by the function h= -16t^2 + 16t + 32, where h is the hei

Amanda [17]

Answer:

Time, t = 2 seconds

Step-by-step explanation:

The height of a flare fired from a 32-foot high platform can be modeled by the function :

$h= -16t^2 + 16t + 32$

Here, h is the height in feet above the ground and t is the time in seconds.

It is required to find the time taken by the flare to reach the ground. When its reaches ground, height covered by it equals 0 such that,

h = 0

$-16t^2 + 16t + 32=0\\\\t=\dfrac{-16+\sqrt{16^2-4\times (-16)(32)} }{2(-16)}, \dfrac{-16-\sqrt{16^2-4\times (-16)(32)} }{2(-16)}\\\\t=-1\ s, 2\ s$

Neglecting t = -1 seconds, the time taken by the flare to reach the ground is 2 seconds.

Misha deposited $3,725 into a savings account 22 years ago. The account has an interest rate of 2.2% and the balance is currentl

Annette [7]

The compounding equation is $A=P(1+ \frac{r}{n}) ^{nt}$ . So

$6012.37 = 3725(1+ \frac{0.022}{n}) ^{22n}$     Divide by 3725

$1.6141= (1+ \frac{0.022}{n}) ^{22n}$

Daily    = $(1+ \frac{0.022}{365}) ^{22*365}$
              = $(1.000060274) ^{8030}$
              = 1.6225
Monthly = $(1+ \frac{0.022}{12}) ^{22*12}$
              = $(1.0018333) ^{264}$
              = 1.6218
Quarter = $(1+ \frac{0.022}{4}) ^{22*4}$
              = $(1.0055) ^{88}$
              = 1.6204
Yearly = $(1+ \frac{0.022}{1}) ^{22*1}$
              = $(1.022) ^{22}$
              = 1.6141

The answer is yearly.
