Equation of a line tha passes through thte point (x1,y1) and has a lsope of m is
y-y1=m(x-x1)

given
m=1/2
point is (2,-1)
x1=2
y1=-1

y-(-1)=1/2(x-2)
y+1=1/2(x-2)
if yo want slope intercept
y+1=1/2x-1
y=(1/2)x-2

I believe the equation would be y=mx+b, m being slope, b being y-intercept, so it would mean that you need to plug in the numbers. I believe the final equation would be y=1/2x+(-1)

The diagram shows an empty cylindrical container. Ana puts a solid cube of side length 8 cm into the container. She then pours 1

Answer:

<h3><u>Cylinder</u></h3>

$\textsf{Volume of a cylinder}=\sf \pi r^2 h \quad\textsf{(where r is the radius and h is the height)}$

Given:

r = 6 cm

h = 18 cm

$\begin{aligned}\implies \sf V &= \sf \pi (6)^2(18)\\& = \sf 648 \pi \: cm^3\end{aligned}$

$\textsf{Volume of a cube}=\sf x^3\quad\textsf{(where x is the side length)}$

Given:

x = 8 cm

$\begin{aligned}\implies \sf V &= 8^3\\& = \sf 512 \: cm^3\end{aligned}$

<h3><u>Volume available to be filled with water</u></h3>

Volume of cylinder - volume of cube

= 684π - 512

= 1532.75204 cm³

1 litre = 1000 cm³

⇒ 1.5 litres = 1000 × 1.5 = 1500 cm³

As 1500 < 1532.75204, the volume of water poured into the container is smaller than the empty space available in the cylinder. Therefore, the water will <u>not</u> come over the top of the container.

Petra jogs 3 miles in 30 minutes. At this rate, how long would it take her to jog 7 miles?

NikAS [45]

30 minutes / 3 miles = 10 minutes for 1 mile

7 miles * 10 minutes per mile = 70 minutes total to run 7 miles
