Answer:

False, XY is not a diameter

Step-by-step explanation:

To be a diameter, it must go through the center of the circle, which is point O

The chord XY does not pass through the point O, so XY cannot be a diameter

Answer:

False

Step-by-step explanation:

XY is the diameter of the circle with the centre of this circle being O.

But O on it's own is just a coordinate, and not the circle.

Read the following description of a

Annette [7]

Answer:

$\sf a = \boxed{\bf 1} \ n+ \boxed{\bf 3}$

Explanation:

$\sf \underline{rate} \ = \ \sf \dfrac{y_2-y_1}{x_2-x_1} \ = \ \dfrac{rise}{run} \ = \ \dfrac{11-10}{8-7} \ = \ \underline{1}$

<u>Equation</u>:

$\Rightarrow \sf a - a1 = m(n - n1)$

$\Rightarrow \sf a - 10 = 1(n -7)$

$\Rightarrow \sf a = n - 7 + 10$

$\Rightarrow \sf a = n + 3$

A new motorboat costs $6000. The value of the boat decreases by 15% each year. What is the value of the boat after 3 years?

Elodia [21]

Answer:

The value of the boat after 3 years is $\$3,684.75$

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$6,000\\r=15\%=15/100=0.15\\x=3\ years$

substitute

$V=6,000(1-0.15)^{3}$

$V=6,000(0.85)^{3}$

$V=\$3,684.75$

Use the graph below to determine a1 and d for the sequence.

Aliun [14]

Answer:

a₁ = 2 and d = 3

Step-by-step explanation:

Consider the sequence given by the values of y, that is

2, 5, 8, 11, 14, 17

The first term in the sequence is a₁ = 2

The common difference is

d = 17 - 14 = 14 - 11 = 11 - 8 = 8 - 5 = 5 - 2 = 3

Thus a₁ = 2 and d = 3
