Can someone help me with this math homework please!

Answer:

It's 2, 1, and y = 2x + 1.

Step-by-step explanation:

You can see the rise is 2 and the run is 1, making the slope = 2, and the y-intercept is 1 because that is where it crosses the y axis. Once you have the slope and y intercept, you can put it in a function, with the form being y=2x+1, the slope being the number before the x and the y-int value being after the x.

Calculate the mass of a liquid with a density of .7892 g/mL and a volume of 121.0 mL.

nataly862011 [7]

Answer:

95.49 g

Step-by-step explanation:

D = m/v

Looking for mass so isolate m to form equation format

D × V = m

Plug in numbers

.7892g/mL × 121.0 mL = 95.4932 g

Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.

Round to sig figs

Both original numbers hold 4 sig figs

95.49 g

Zolol [24]

Answer:

The area of the shaded region is 125.664 square centimetre

Step-by-step explanation:

Area of the shaded region = area of the circle with radius 7 cm - area of the circle with radius 3 cm----------------(1)

<u>Step 1: Finding the area of the circle with radius 7 cm</u>

Area of the circle A = $\pi r^2$

On substituting the value of the radius, we get

Area of the circle A = $\pi(7)^2$

Area of the circle A = $49 \pi$ square centimetre----------------(2)

<u>Step 2: Finding the area of the circle with radius 3 cm</u>

Area of the circle a = $\pi r^2$

On substituting the value of the radius, we get

Area of the circle a = $\pi (3)^2$

Area of the circle a = $9 \pi$ square centimetre ----------------(3)

<u>Step 3: Finding the area of the shaded region</u>

Area of the shaded region = $49 \pi - 9\pi$

= $40 \pi$

= 125.664 square centimetre
