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
6. Solve for x: 23x+1 = 210
Please please give detailed steps!! thank you
Answer:
x = 3
Step-by-step explanation:
Given
[tex]2^{3x+1}[/tex] = [tex]2^{10}[/tex]
Since bases on both sides are equal, both 2, then equate the exponents
3x + 1 = 10 ( subtract 1 from both sides )
3x = 9 ( divide both sides by 3 )
x = 3

how to find endpoint? please give good explanation
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.
~
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]

Find the y-intercept
of the line on the
graph?
9514 1404 393
Answer:
(0, -3)
Step-by-step explanation:
The y-intercept is the point where the graph crosses the (vertical) y-axis. That point is halfway between grid lines marked -2 and -4, so is at the grid line with the value -3. The x-coordinate there is 0, so the y-intercept point is ...
(x, y) = (0, -3)
_____
Since the y-intercept always has an x-coordinate of 0, we sometimes refer to the y-intercept using only the y-value: -3.
Solve for r -2r+4 < -9r-6
Answer:
r < -5/4
Step-by-step explanation:
r -2r+4 < -9r-6
Combine like terms
-r +4 < -9r-6
Add 9r to each side
-r + 9r+4 < -9r-6+9r
8r+4 < -6
Subtract 4 from each side
8r +4-4 < -6-4
8r < -10
Divide by 8
8r/8 < -10/8
r < -5/4
Answer:
[tex]r = \frac{ - 10}{8} [/tex]
Step-by-step explanation:
[tex]r - 2r + 4 < - 9r - 6 \\ r - 2r + 9r < - 4 - 6 \\ - r + 9r< - 10 \\ 8r < - 10 \\ r = \frac{ - 10}{8} [/tex]

A can of tomatoes has a radius of 6 cm and a height of 10 cm. What is the approximate volume of the can?
A:36 cm3
B:60 cm3
C:113 cm3
D:1,130 cm3
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
Answer:
The choose D. 1130 cm³
v = r² pi/ h
v = (6)² × 3.14 × 10
v = 1130.4
v = 1130

Find the area of the shaded region.
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.

Answer:
DAC=18(corresponding angles)
EAD= 162 degrees
Step-by-step explanation:
DAC=18(corresponding angles)
EAD=180-18(angles on a straight line)
EAD= 162 degrees
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°
or, <EAD=162°
Thus, <DAC=18° and<EAD=162°.

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)
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

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

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
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.

99x + 9
The greatest common factor is 9 so put 9 outside of parenthesis
9(11x+9)
Answer:
9(11x+1)
Step-by-step explanation:
We can see that these two values in the equation can be factored by 9 so divide both by 9
99/9= 11
9/9= 1
Rewrite expression by inputting the numbers in parenthesis while keeping the 9 "outside"
