The exponential growth rate is obtained as 0.1099.
What is the rate of multiplication?Now we know that an exponential function has to do with an exponential increase or decrease. An exponential function could increase or decrease and this means that the constant of the function could be a decay constant or a growth constant.
When we have an exponential function, we have to apply the general formula; P(t) = P(o)e^rt
Po = initial number
P(t) = number at time t
r = rate of growth
t = time taken
Thus;
270=90e^10r
270/90 = e^10r
3 = e^10r
ln3 = 10r
r = ln3/10
r = 0.1099

P(t) = 90e^(0.1099 * 13)

How to recognize the domain, the range and the axis of symmetry in a graph?
Answer: Read below.
Step-by-step explanation: To recognize the domain of a graph, you have to find out what points does the graph cross the x-axis? For example, consider the equation, y = x. The domain for this graph is all real numbers, or (-∞, ∞). This is because, the graph goes infinitely forever, and eventually hits every single number in the x-axis. This is true for every single linear graph in the form y = mx + b or ax + by = c. However, in a graph that is an inequality, like let's say, x < 4, then there will be an open dot on 4, and the graph will go to the left infinitely, hitting every single number in the negative x-axis eventually. The interval for this would be (-∞, 4).
The range is as easy as the domain to figure out. Instead of all the values that the graph goes on the x-axis, we need to find all the values that the graph goes on the y-axis. Again, for a linear graph in the form y = mx + b or ax + by = c, the range is also (-∞, ∞). For an inequality though, like y ≥ 2, the graph would have a closed plot on 2 in the y-axis, and go infinitely in the direction of the right, hitting every single y value after 2 eventually. The interval would be [2, ∞).
The axis of symmetry can only be found in parabolas. In parabolas, the axis of symmetry is an invisible vertical or horizontal line (depending on if your parabola is sideways or not.) The invisible line cuts through the vertex of the parabola, or the center of the parabola, and splits it into two even and equal pieces. Thus, the axis of symmetry will always be the x-coordinate of the parabola if upwards or downwards, or the y-coordinate of the parabola if sideways.

The ratio is: 450g to 1kg
In it's simplest form
Answer:
9:20
Step-by-step explanation:
1kg is 1000g grams and in order to simify we need the units to be equal . 450:1000 would simplify to
45: 100 by divinding both the number by 10 then divide both number by 5 which would give 9: 20
hopefully this helped . if you need any more explanation pls ask
pls give brainliest if you like my answer :) thanks
Answer:
9: 20
Step-by-step explanation:
First, we have to convert both figures into the same unit.Here we can convert both into grams.As 450g is already given in grams, let us convert 1kg into grams.To convert kilograms into grams we have to multiply kilograms by 1000.Therefore,1kg × 1000 = 1000g
Now let us write those as a ratio.450 : 1000g
450 : 1000
To write the ratio in the simplest form we can divide both by 50.9: 20
As this cannot be simplified anymore, the simplest form of 450: 1000 is 9: 20.If each interior angle of a regular polygon measures 157.5°, how many sides does it have?

the sides of each square have a length of 3 inches. what is the perimeter of Edgar's check boar
Answer:
(b) 96 inches
Step-by-step explanation:
The perimeter of the board is the sum of its four edge lengths.
Edge lengthEach edge of the board is indicated as being 8 squares long. Each square is 3 inches on a side, so the edge of the board is ...
8 × (3 in) = 24 in . . . . board edge length
PerimeterThe perimeter of the board is 4 times the length of one edge, so is ...
P =4s = 4(24 in) = 96 in
The perimeter of Edgar's checkerboard is 96 inches.
__
Scaled geometry (alternate solution)The perimeter of one small square on the board is ...
P = 4s = 4(3 in) = 12 in

To get this answer, we first have to add the numerators.
We can easily say that 4 + 8 = 12
That leaves us with the improper fraction, [tex]\frac{12}{5}[/tex].
To make this fraction proper, we must first find out how many times 5 can go into 12.
5 can go into 12 two times which leaves us with 2 left over from the numerator.
Now all that's left to do is add 2 (the amount of times 5 can go into 12) and [tex]\frac{2}{5}[/tex] (the left over fraction) to get the answer 2[tex]\frac{2}{5}[/tex].

1.16 / 0.29 = 4
Mason will get 4 oranges on spending 1.16$
What is Rate of change?
A rate is anything that can be measured over time. Common rates include velocity (which is the rate of distance traveled), power (rate of work being done), etc. All these have one thing in common which is that they are all divided by the amount of time it took to obtain a certain measurement.
Here it is given that a grocery store sells a bag of 7 oranges for $2.03,
Now firstly let calculate for 1$ how many oranges Mason get by dividing 7 with 2.03$ :
For 1$ we get = 7/2.03 = 3.5 oranges
Therefore to calculate for 1.16 $ amount spend by Mason will be multiplication of 3.5 with 1.16$ : 3.5 x 1.16 = 4 oranges
Therefore, Mason will get 4 oranges on spending 1.16$

Identify the area of the figure rounded to the nearest tenth.
Please give an Explanation :)
Answer:
67.5 cm²
Step-by-step explanation:
The figure can be decomposed into figures whose area formulas you know.
DecompositionAs the attached figure shows, one way to decompose the figure is by extending the horizontal line. This divides the figure into an upper trapezoid and a lower rectangle.
TrapezoidThe area of a trapezoid is given by the formula ...
A = 1/2(b1 +b2)h
where b1 and b2 are the parallel bases, and h is the height.
The bases of the trapezoid in this figure are 6 and 3 cm, and the height is 5 cm. Its area is ...
A = 1/2(6 cm +3 cm)(5 cm) = 22.5 cm²
RectangleThe area of a rectangle is given by the formula ...
A = LW
where L and W represent the length and width, respectively.
The dimensions of the rectangle in this figure are 15 cm long by 3 cm wide. Its area is ...
A = (15 cm)(3 cm) = 45 cm²
Total areaThe total area of the figure is the sum of the areas of the trapezoid and rectangle:
A = (22.5 cm²) + (45 cm²) = 67.5 cm²
The are of the figure is 67.5 cm².
Can you solve and explain how to solve problems like these.
Step-by-step explanation:
there are some formulas to know about this.
I am sure you discussed this in class.
when 2 lines (originating from the same point) cut through the same circle creating some circle segments (such lines are also called Secants), then there is a relationship in the lengths of the different parts of the lines among themselves.
the outer portion of such a line multiplied with the length of the whole line to the second point it intersects the circle is the same for every secant from the same point through the same circle.
that means in our case :
7(x - 6) = 6(x - 3)
7x - 42 = 6x - 18
x = 24
and so,
EG = (x - 3) + 6 = (24 - 3) + 6 = 21 + 6 = 27

A bag has marbles labeled ‘4’ and ‘7’ and a spinner has 3 options, What is the probability of drawing a number less than 8 or spinning a 4?
Answer:2
Step-by-step explanation:
im just guessing
The answers are :
P (Drawing a number < 8) = 1
P (Spinning a 4) = 0
There are only 2 numbers in the bag, 4 and 7, both of which are less than 8. Hence, as it is a sure event, the probability of the event is 1.
There are only 3 numbers on the spinner, 1, 2, and 3. As 4 is not on the spinner, it is an impossible event, hence the probability of the event is 0.

3x^5 - 4x^4 - 11x^3 + 2x^2 - 10x + 15 = 0
Which equation can be solved using the given system of equations?
Here we have the system of equations:
y = 3x^5 - 5x^3 + 2x^2 - 10x + 4
y = 4x^4 + 6x^3 - 11
Notice that both x and y should represent the same thing in both equations, then we could write:
3x^5 - 5x^3 + 2x^2 - 10x + 4 = y = 4x^4 + 6x^3 - 11
If we remove the middle part, we get:
3x^5 - 5x^3 + 2x^2 - 10x + 4 = 4x^4 + 6x^3 - 11
Now, this is an equation that only depends on x.
We can simplify it to get:
