Answer:
[tex]L(t) = 1,100*(1+0.87)^{\frac{t}{2.4}}[/tex]
Step-by-step explanation:
The locust population grows according to an exponential model with the following general formula:
[tex]L(t) = L_0*(1+r)^{\frac{t}{T}}[/tex]
Where 'L0' is the initial locust population, 'r' is the increase rate after 'T' days, and 't' is the time passed, in days.
Applying the given data, the function that models the locust population t days since the first day of spring is:
[tex]L(t) = 1,100*(1+0.87)^{\frac{t}{2.4}}[/tex]

Answer:
18.5
Step-by-step explanation:
First find the area of the two triangles.
1.5 * 1.5 = 2.25
Find the area of the two top rectangles: 2.5 * 1.7 * 2 = 8.5
Finally, find the area of the floor: 1.5 * 2.5 = 3.75
2.25 + 8.5 + 7.75 = 18.5

Answer here
I
Answer:
We add 11 to each side to get rid of -11 so x = -18 + 11 = -7.
Answer:
x = -7
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Add 11 to both sides:
x + (-11) = -18
x - 11 = -18
x - 11 (+11) = -18 (+11)
x = -18 + 11
Simplify. Combine like terms:
x = -18 + 11
x = -7
x = -7 is your answer.

A right triangle has a hypotenuse with length 13 in. and a leg with length 12 in. Find the area of triangle
Answer:
[tex]30 {in}^{2} [/tex]
Step-by-step explanation:
First we have to find the value of the other leg of the triangle. To find that we can use the PYTHAGORAS theorem because this is an right triangle.
[tex] {h}^{2} = {p}^{2} + {b}^{2} \\ {13}^{2} = {12}^{2} + {b}^{2} \\ 169 = 144 + {b}^{2} \\ 169 - 144 = {b}^{2} \\ 25 = {b}^{2} \\ b = \sqrt{25 } \\ b = 5 \: \: in[/tex]
Now let's find the area.
[tex]area = \frac{1}{2} \times base \times height \\ = \frac{1}{2} \times 5 \times 12 \\ = \frac{60}{2} \\ = 30 {in}^{2} [/tex]

m2.
If the length of the pool is 79 m, what is its width?
Width of the pool:
m
Answer:
w= 69 meters
Step-by-step explanation:
if u want to find the width u need to divide
area equals l times w
w equals area divided by l
l equals area divided by w
we need to find width
so w= 5451 divided by 79
w= 69

A hovercraft takes off from a platform. It’s height (in meters), x seconds is modeled by h(x)=-(x-11)(x+3). What is the height of the hovercraft at the time of the takeoff?
Answer:
The height of the hovercraft at the time of takeoff is 33 meters.
Step-by-step explanation:
Height of hovercraft x seconds after takeoff = h(x) = -(x - 11)(x + 3)
Height after takeoff is = h(0) = -(0 - 11)(0 + 3) = -(-11)(3) = 33
So the correct answer is 33 meters. The height of the hover craft at the time of the takeoff is 33 metres.
Answer: 33 meters.

HELP!!!
Answer:
9x + 25 + 3x = 34 + 54
9x + 3x = 12x
34 + 54 = 88
12x + 25 = 88
- 25 - 25
12x = 63
x = 5.25
Answer:
x = 21/4 = 5 1/4
Step-by-step explanation:
9x +25+3x = 34 + 54
Combine like terms
12x+25 = 88
Subtract 25 from each side
12x+25-25 = 88-25
12x =63
Divide by 12
12x/12 = 63/12
x = 21/4

If ABC is reflected across the y-axis, what are the coordinates of A? A (1-3)
B. (-1, -3)
C. (5,-3)
D. (-1,3)
Answer:
d. (-1, 3)
Step-by-step explanation:
Reflecting across y axis means the x coordinate will change.
Imagine a mirror image of the triangle on the other side of Y axis.
A's coordinates on the right are (1, 3)
So if we flip across Y the coordinates will now be (-1, 3)
3 stays the same because it is still in the same position vertically.
The correct option will be Option B: When ABC is reflected about the y-axis, then the coordinate of A will be(-1,-3).
What is reflection?Reflection is the transformation of the picture about an axis so that the distance of the reflected image from the axis is the same as the distance of the original image from the axis.
When a point of coordinate (x,y) is reflected by the y-axis then the coordinate of the reflected point will be of coordinate (-x,y).
Given that the triangle ΔABC is reflected across the y-axis.
The coordinate of point A is (1,-3).
When point A of triangle ΔABC is reflected by the y-axis, then the coordinate of y will not change. The mirror image of the triangle will be on the other side of the y-axis.
As we know When a point of coordinate (x,y) is reflected by the y-axis then the coordinate of the reflected point will be of coordinate (-x,y).
Then the coordinate of the reflected point A will be (-1,-3).
Therefore when ABC is reflected about the y-axis, then the coordinate of A will be(-1,-3).

Answer:
32 degrees.
Step-by-step explanation:
So every triangle =180 degrees.
Firstly, 14 + 45 = 59
Secondly, 180 - 59 = 121
so angle AEB = 121 degrees.
Using vertical angles theorum, angles AEB and CED are equal to each other
so CED = 121 degrees.
121 + 27 = 148
then 180 - 148 = 32
Angle D = 32 degrees

You pick a card at random from an ordinary deck of 52 cards. If the card is an ace, you get 9 points; if not, you lose 1 point. 2 lines connect and go up to the right and down to the right. The line that goes up to the right points to Ace, and the line that goes down to the right points to Not an ace. StartFraction 4 Over 52 EndFraction is above the lines, and StartFraction question mark Over 52 EndFraction is below the lines. Write the equation for the expected value. E(V) = 4 52 (a) + b 52 (c) a = b = c =
The equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
How to determine the equation of the expected valueIn a standard deck of cards, there are:
Ace = 4
Cards = 52
So, the probability of selecting an ace is:
[tex]p = \frac{4}{52}[/tex]
Simplify
[tex]p = \frac{1}{13}[/tex]
The probability of not selecting an ace is calculated using the following complement rule
[tex]q = 1 - \frac{1}{13}[/tex]
Simplify
[tex]q =\frac{12}{13}[/tex]
The expected value is then calculated as:
[tex]E(x) = \sum x * P(x)[/tex]
This gives
[tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
Hence, the equation of the expected value is [tex]E(x) = 9 * \frac{1}{13} - 1 * \frac{12}{13}[/tex]
