Answer 1

Answer:

initial population : 89

after 9 years : 676

Step-by-step explanation:

no need for panic. this is just plain calculator mechanics. yes, we need to do some more complicated typing and use e, but it is still only typing.

the initial population is P(0). or t = 0.

simply when there were 0 years since the fish were added.

that is simple.

we get (as -0.42×0 = 0)

800 / (1 + 8e⁰) = 800 / (1+8×1) = 800 / 9 ≈ 89

now, after 9 years we have to calculate P(9). or t=9.

let's pre-calculate : -0.42×9 = -3.78

e to the power of -3.78 = 0.022822691...

8 times this is 0.182581531...

and plus 1 is 1.182581531...

800 / 1.182581531... = 676.486127 ≈ 676

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
VX
O(x, y) - (x + 5, y-3)
O(x,y) → (x + 5, y + 3)
(x, y) (x-3, y + 5)
O(x,y) → (X + 3, y + 5)

Answers

Answer:

Step-by-step explanation:

5 units up means y is crease by y =>

y+5

and x unit left means x is decreasedby 3

=> x-3

thus new coordinates are (x-3,y+5)

Thus (x,y) → (x − 3, y + 5) (x, y) is

correct

Find the area of the shaded region.​​

Answers

There are four parts of a circle, so you have to find out the area of the circle:-

10 cm=Radius

[tex]10^{2}[/tex]=100

[tex]\pi[/tex]=3.14

3.14*100=314 [tex]cm^{2}[/tex]

Now, find the area of the square box:-

Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.

Area=S*S

=20*20=400 [tex]cm^{2}[/tex]

Now subtract the area of the box from the area of the square:-

400-314= 86 [tex]cm^{2}[/tex]

That is the area of the shaded part.

Answers

Answer:

D: 1,130 cm³

Step-by-step explanation:

You need the volume of  a cylinder.

V = πr²h

V = 3.14159 * (6 cm)² * 10 cm

V = 3.14159 * 36 cm² * 10 cm

V = 1130.97 cm³

Answer: D: 1,130 cm³

how to find endpoint? please give good explanation ​

Answers

Answer:

(-11 , -16)

Step-by-step explanation:

The midpoint will always be, as the term suggests, in the middle of the line segment. You simply need to find the distance for both x & y, and to apply that to the midpoint. In this case:

Endpoint (x₁ , y₁): (5 , 10)

Midpoint (x₂ , y₂): (-3 , -3)

Note that when finding distance, you will subtract the point₂ from point₁:

x: 5 - (-3) = 8

y: 10 - (-3) = 13

Therefore, each time you plot another point, you will be subtracting 8 from the x value, and 13 from the y value:

Endpoint (x₃ , y₃) = Midpoint (-3 , -3) + (_ - 8 , _ - 13) = (-11 , -16)

(-11 , -16) is your answer.

~

Let other endpoint be (x2,y2)One endpoint(5,10)Midpoint(-3,-3)

Using midpoint formula

[tex]\boxed{\sf (x,y)=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)}[/tex]

[tex]\\ \rm\longmapsto (-3,-3)=\left(\dfrac{5+x_2}{2},\dfrac{10+y_2}{2}\right)[/tex]

Firstly

[tex]\\ \rm\longmapsto \dfrac{5+x_2}{2}=-3[/tex]

[tex]\\ \rm\longmapsto 5+x_2=2(-3)=-6[/tex]

[tex]\\ \rm\longmapsto x_2=-6-5[/tex]

[tex]\\ \rm\longmapsto x_2=-11[/tex]

Now

.[tex]\\ \rm\longmapsto \dfrac{10+y_2}{2}=-3[/tex]

[tex]\\ \rm\longmapsto 10+y_2==2(-3)[/tex]

[tex]\\ \rm\longmapsto 10+y_2=-6[/tex]

[tex]\\ \rm\longmapsto y_2=-6-10[/tex]

[tex]\\ \rm\longmapsto y_2=-16[/tex]

Hence the coordinates are

(x2,y2=(-11,-16)

If AED is 95°, find
the measure of
CEB.
Reason:

Answers

Answer:

Angle AED = Angle CEB —> Opposite angles

So; Angle CEB = 95°

I hope I helped you^_^

∠AED and ∠CEB are opposite angles so they will be the same so ∠CEB will also 95°.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Two opposite angles become by the intersection of two lines will always same.

Since E is the intersection point so ∠AED and ∠CEB are opposite angles.

So,

∠AED = ∠CEB

∠CEB = 95°.

Hence "∠AED and ∠CEB are opposite angles so they will be the same so ∠CEB will also be 95°".

Answer:

Here, we have,

<HBA=18°

<DAC=?

<EAD=?

Now,

i)<DAC=<HBA=18°[being corresponding angle]

ii)<EAD+<DAC=180°[being straight angle]

or, <EAD+18°=180°

or, <EAD=180°-18°

Thus, <DAC=18° and<EAD=162°.

A triangle has a perimeter of 75 inches. Find the length of three sides
if one side is 15 inches larger than the smallest side, and the third
side is twice the smallest

Answers

Answer:

The side lengths are:

15, 30, and 30

Step-by-step explanation:

Let x determine the length of the smallest side length then

the other one is said to be 15 in larger so it's x + 15

finally the third size is said to be twice as the smallest one so it's 2x

The perimeter is the sum of all three sides added up

x + 2x + x + 15 = 75 add like terms

4x + 15 = 75 subtract 15 from both sides

4x = 60 divide both sides by 4

x = 15

A percentage is a way to describe a part of a whole. The value of x is 5,000.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that 8.4% of x is 420. Therefore, we can write the given statement in the form of an equation as,

8.4% of x = 420

8.4% × x = 420

(8.4/100) × x = 420

x = (420 × 100)/8.4

x = 5,000

Hence, the value of x is 5,000.
