Answer:

(1,0)

(5,24)

(-2,3)

Step-by-step explanation:

So we want y=x^2-1 per point.

Let's check them.

(0,1)? Plug in 0 for x and see what y is:

y=0^2-1

y=0-1

y=-1 which is not 1.

(1,0)? Plug in 1 for x and see what y is:

y=1^2-1

y=1-1

y=0 which is what we have for y.

(3,5)? Plug in 3 for x and see what y is:

y=3^2-1

y=9-1

y=8 which is not 5.

(5,24)? Plug in 5 for x and see what y is:

y=5^2-1

y=25-1

y=24 which is what we have for y.

(-2,3)? Plug in -2 for x and see what y is:

y=(-2)^2-1

y=4-1

y=3 which is what y is.

(-4,-17)? Plug in -4 for x and see what y is:

y=(-4)^2-1

y=16-1

y=15 which is not -17.

Explain how you would solve a triangles given two sides and the included angle?

Len [333]

When you are trying to find the side lengths you can use the law of sines. The law of sines goes like this: (Sin A (angle a))/A (side length) =(Sin B (angle b))/B (side length)

1) A microbiologist measures the length of a bacterium of 0.000163 m and the

sashaice [31]

Answer:

a) The bacterium is longer;

b) The bacterium is 0.1543 mm longer than the yeast.

Step-by-step explanation:

In order to compare the length of the two beings we need to convert them to the same unit. We can do it either way, but we'll choose to convert from meters to milimetres, since we're dealing with small numbers. To do that we need to multiply the length that is in "m" by 1000.

$length_{bac} = 0.000163*1000 = 0.163 \text{ mm}$
