Answer:

1) 27/128 ft³

2) 40cm³

Step-by-step explanation:

1) The diagram is a cuboid not a prism.

Volume of the shape = Length × Breadth × Height

Given the following dimension

Length = 3/8 ft

Breadth = 3/4 ft

Height = 3/4 ft

Volume = 3/8 × 3/4 × 3/4

Volume of the shape = 27/128 ft³

2) Volume of a rectangular prism = Base Area × Height

Given base area = 12cm²

Height of the prism = 3 1/3 cm

Volume = 12 × 3 1/3

Volume = 12 × 10/3

Volume = 4 × 10

Volume of the prism = 40cm³

The point (-3,1) is moved 3 places in the negative y direction and 2 places in the positive x direction.

luda_lava [24]

Answer:

(-6, 4)

Step-by-step explanation:

Given the coordinate points (-3,1). If The point (-3,1) is moved 3 places in the negative y direction and 2 places in the positive x direction the required coordinate will be expressed ss;

X' = (-3-3, 1+3)

X = (-6, 4)

Hence the resulting coordinate will be at:(-6, 4)

What are the coordinates of the circumcenter of a triangle with vertices A(−3, 3) , B(−1, 3) , and C(−1, −1) ?

Shtirlitz [24]

Hello Missjay12,

Step 1 :
From the coordinates we have to find the slopes and midpoints of the lines.

Step 2 :
Find the slope of the bisectors and now find the equations of two lines by using slope and one mid points.

Step 3 :
Solve any two pair of equations and find the intersection point.

Step 4 :
The point thus found is the circumcenter of the given triangle.

so<span> the coordinates of the circumcenter of a triangle with vertices A(−3, 3) , B(−1, 3) , and C(−1, −1)</span> is, -4, 0.

Eliminate the parameter. X=sqrt of t y = 2t+5

tankabanditka [31]

X = sqrt
t = x^2

y = 2t + 5
2t = y - 5
t = (y - 5)/2

so x^2 = (y - 5) / 2

2x^2 = y - 5

y = 2x^2 + 5

Suppose that poaching reduces the population of an endangered animal by 6% per year. Further suppose that when the population o

artcher [175]

If poaching reduces the population of an endangered animal by 6% and the criteria of population extinction is 20 with present population 1500 then it will take 3.62 years to reach to the mark of extinction.

Given Poaching reduces the population of endangered animals by 6% per year. The criteria of population extinction is 20. Present population being 1500.

Number of years taken by the population of endangered animals to reach to 20 mark can be calculated as under:

20=1500* $(1-0.06)^{n}$

20=1500* $0.94^{n}$

20/1500= $0.94^{n}$

0.133= $0.94^{n}$

take log both sides

log(0.133)=log $0.94^{n}$ -------1

log(0.133)=nlog (0.94)

put the values log values:

log(0.133)=-0.8761

log(0.94)=-0.0268

Taking 1

-0.8761=n*(-0.0268)

n=0.8761/0.0268

n=3.269

Hence to reach level of 20 the population takes 3.2 years.
