It's a rectangle.
It clearly shows the outline of the shape presented.
the number is a prime
the number is less than 19
the sum of the digits of the number is greater than 7 please
Answer:
17
Step-by-step explanation:
okay so we know its double digit and less than nineteen so... 11 through eighteen. now we just find the prime numbers.
11
13
17
Now to finally narrow it down.
1+1=2 so 11 doesn't work
1+3= 4 so 13 is a no-go
1+7=8 so BLAMMO

Answer:
14
Step-by-step explanation:
the full length of the line is 17, half of it is 3.
subtract line LN from MN to get LM.
17-3=14
Answer:
LN=4
Step-by-step explanation:
A scientist is studying some rabbits. A disease is killing the rabbits. A population of 240 of these rabbits was reduced to 180 rabbits in two days. The rabbit population is decreasing exponentially. Work out how many of the 240 rabbits will still be alive at the end of 7 days (5 marks)
Here we have a problem with exponential decays, we will find that we can expect that 110 rabbits will still be alive at the end of 7 days.
An exponential decay can be written:
P(x) = A*e^(-k*x)
Where:
A is the initial amount.
k defines the rate of decrease.
x is our variable.
In this case, the exponential decay is applied to the population of rabbits, and we know that:
The initial population is 240, then A = 240
P(x) = 240*e^(-k*x)
We also know that after two days (at x = 2) the population was 180, then we can write:
P(2) = 180 = 240*e^(-k*2)
With this equation we can find the value of k:
180 = 240*e^(-k*2)
180/240 = e^(-k*2)
Now remember that:
Ln(e^n) = n
then if we apply the natural logarithm to both sides, we get:
Ln(180/240) = Ln(e^(-k*2)) = -k*2
-Ln(180/240)/2 = k = 0.144
Then the equation is:
P(x) = 240*e^(-0.144*x)
Now with this, we can find the population of rabbits after 7 days, we just need to evaluate the above function at x = 7, we will get:
P(7) = 240*e^(-0.144*7) = 110.3
That we could round down to the next whole number, 110.
Concluding, we can expect that 110 rabbits will still be alive at the end of 7 days.

y = 2-2x
y = -16 + 2(x-3)^2
Answer:
y = -26
Step-by-step explanation:
[y = 2 - 2x] + [y = -16 + 2(x - 3)^2]
y = -16 + 2x - 6^2
y = -16 + 2x - 6^2 + 2 - 2x
y = (+2x - 2x) - 16 - 6^2 + 2
y = -16 - 6^2 + 2
y = -16 - 12 + 2
y = - 28 + 2
y = -26

The top face (BCD) and the front face (EHD) both contain the line segment AD.
Answer: Choice BName the plane that is highlighted in the diagram below.
We want to define the name of a plane. We will find that some of the possible names are:
IJF, JFE, FEI.
To define any given plane, we can just use two collinear points that are on the plane and a third point, which is on the plane and is not-collinear to the other two points.
Remember that points are collinear if we can connect them with a line.
So for the shown plane, some names can be:
IJF
where IJ are two collinear points and F is the third point that is non-collinear to the other two and also is on the plane.
Other names can be:
JFE
FEI
etc.

Step-by-step explanation:
the side length = [tex]\sqrt{105}[/tex]
Consider perfect squares either side of 105 , that is
100 < 105 < 121 , then
[tex]\sqrt{100}[/tex] < [tex]\sqrt{105[/tex] < [tex]\sqrt{121}[/tex] , so

Write each decimal number as a fraction or mixed number in simplest form?
You're letting x = 0.325325325…, which means
1000x = 325.325325325… (or 325.325, but pretend the underline is actually an overline)
Then the next box you'd fill in with 0.325325325… (or 0.325).
Subtracting these, you have
1000x - x = 325.325325325… - 0.325325325…
999x = 325
Finally, solving for x gives
x = 325/999
Which of the following are the coordinates of the vertex of y = −x2 + 2x + 1? (2, 1) (1, –2) (1, 2) (–2, 1)
Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:
[tex]\displaystyle y = -x^2 + 2x + 1[/tex]
Recall that the vertex is given by the formulas:
[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]
In this case, a = -1, b = 2, and c = 1.
Determine the x-coordinate of the vertex:
[tex]\displaystyle x = -\frac{(2)}{2(-1)} = 1[/tex]
To determine the y-coordinate, evaluate the function at x = 1:
[tex]\displaystyle \begin{aligned} y(1)&= -(1)^2 + 2(1) + 1 \\ &= 2\end{aligned}[/tex]
In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.

What is the domain and range of this graph?
Answer:
Domain: [-5, 5)
Range: (1, 3]
Brackets and parenthesis are important! Make sure to put them in the correct spot
Step-by-step explanation:
Domain is which x values the line hits. It hits from -5 to 5 but doesn't include 5 as indicated by the open circle.
Range is which y values the line hits. It hits from 1 to 3 but doesn't include 1 because, again, there is an open circle.
When a number is not included, you put it with a parenthesis.
When it is included, you put it with a bracket.

Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11

1. y = (2/3)x - 1
y = -x + 4
System of Linear Equations entered :
[1] y - 2x/3 = -1
[2] y + x = 4
// To remove fractions, multiply equations by their respective LCD
Multiply equation [1] by 3
// Equations now take the shape:
[1] 3y - 2x = -3
[2] y + x = 4
Graphic Representation of the Equations :
-2x + 3y = -3 x + y = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + 4
// Plug this in for variable x in equation [1]
[1] 3y - 2•(-y +4) = -3
[1] 5y = 5
// Solve equation [1] for the variable y
[1] 5y = 5
[1] y = 1
// By now we know this much :
y = 1
x = -y+4
// Use the y value to solve for x
x = -(1)+4 = 3

for question 4, 1/3 is the probability since there are 6 sides and there are two numbers on a die less than 3, 2 and 1.
2 and 1 are 2 of the 6 numbers on the die.
so 2/6
but we have to simplify!
divide 2 by 2 and 6 by 2
1/3 done!
Step-by-step explanation:
Explanation:
The set of outcomes we want to happen is {1,2}. These items are less than 3. We have A = 2 outcomes here.
There are B = 6 total outcomes in the set {1,2,3,4,5,6} which are values on a standard cube.
The probability we want is A/B = 2/6 = 1/3
line mp bisects angle kmn,line mq bisects angle lmp, and line mr bisects angle qmp. if the measure of angle rmp is 21, find the measure out angle lmn
Bisection is a process that produces two equal parts of angles or lines. Thus applying the bisection principle, the measure of angle lmn = [tex]168^{o}[/tex]
This question deals with sub-bisection of angles. Bisection is the method required to divide a given angle or line into two equal parts.
From the given question: m<rmp = [tex]21^{o}[/tex] (given)
But,
m<qmp = m<rmp + m<qmr = 2 x m<rmp (addition property of bisected angles)
= 2 x [tex]21^{o}[/tex]
m<qmp = [tex]42^{o}[/tex]
Also,
m<lmp = m<lmq + m<qmp = 2 x m<qmp (addition property of bisected angles)
= 2 x [tex]42^{o}[/tex]
m<lmp = [tex]84^{o}[/tex]
Then,
m<lmn = m<lmp + m<pmn = 2 x m<lmp (addition property of bisected angles)
= 2 x [tex]84^{o}[/tex]
m<lmn = [tex]168^{o}[/tex]
Thus, the measure of angle lmn is [tex]168^{o}[/tex].
