B is -5 and C is -2. Since -5 is the first number, a(1) is bc^0 and that would make c = 1. B would need to be -5. In the second number, since we know b is -5, c would need to be -2 and anything to the 2-1 is just the same value.

A naval engineer uses the function, P, to analyze the effects of water pressure on submarines. The function P(d) measures the pr
saw5 [17]

The function that the naval engineer uses related P (pressure) and d (depth of ocean).

<em>Is there any restriction on the domain ( d: depth of the ocean)? Yes!</em>

The domain would be from 0 (at sea level or 0 depth) until the depth of the ocean (which is not infinite). Hence, we can write:

0\leq d\leq DepthOfSeaFloor

Choice D is the correct one.

Points (3,2) and (-5,6) are endpoints of the diameter of a circle.
vichka [17]

Answer:

A.8 B.(-1,4) C.(1,4)

Step-by-step explanation:

First, know that (3,2)=(x1,y1) and (-5,6)=(x2,y2)

A. The diameter is 8, given the diference between x1 and x2: 3-(-5)=8

B. The center point is given by (x1+x2)/2 and (y1+y2)/2

(x1+x2)/2 and (y1+y2)/2 = (3-5)/2 and (2+6)/2 = (-1,4)

C. The symmetric point of C about the x-axis is (1,4)

Shalinda wants to leave an 18% tip for her
ki77a [65]

Hello There! Shalinda's total is $29.62.

Our first step is to find 18% of $25.10. To do this, multiply 25.10 by 0.18.

25.10 x 0.18 = 4.518 (Which can be rounded up to 4.52)

So, this gives us the tip, but the question is asking what her total is, including the tip. To find her total, add the price before tip and the tip together.

25.10 + 4.52 = 29.62

So, her total with the tip is $29.62! I hope this was helpful, have a great day!
