Find the surface area of the prism.
Answer:
[tex]A=202\ cm^2[/tex]
Step-by-step explanation:
Given that,
The dimensions of the prism are 4 cm, 9 cm and 5 cm respectively.
The formula for the surface area of the prism is given by :
[tex]A=2(lb+bh+hl)[/tex]
Put all the values,
[tex]A=2(4(9)+9(5)+5(4))\\\\A=2(36+45+20)\\\\A=202\ cm^2[/tex]

A number in scientific notation has the form
N

10
a
, where
N
is a number between 1 and 10, and
a
is a positive or negative integer.
To convert to scientific notation, you move the decimal point until the new form is a number between 1 and 10 (
N
) and then record the exponent (
a
) as the number of places the decimal point was moved.
If you move the decimal to the right, the exponent is negative.
Express

Step 1. Move the decimal place to the right to create a new number between 1 and 10.
This gives
N

4. 2x2 + 4x + 10 = 0
Answer:
Step-by-step explanation:
This doesn't factor. Not only that, but it does not give real results. The discriminate is negative.
a = 2
b = 4
c = 10
You could divide this equation by 2
a = 1
b = 2
c = 5
These three are smaller and easier to calculate. The answer will be the same.
x = (- b +/- sqrt(b^2 - 4*a*c ) / (2 a)
x = (-2 +/- sqrt(^2 - 4(1)*(5) ) / 2*1
x = (-2 +/- sqrt(4 - 20) ) / 2
X = (-2 +/- sqrt(-16) ) /2
x = (-2 +/- 4i ) / 2
x = ( - 1) +/- 2i
Carl went out for breakfast.
• The price of his meal was $12.35.

• The tip was 25% of the price of the meal and the sales tax.
To the nearest cent, how much total money did Carl pay for breakfast including the price of his meal, sales tax, and tip?
Answer: $16.60
Step-by-step explanation:
Price + Tax = 12.35+0.93
Total + tip = 13.28+3.32
total: 16.60
The total money did Carl pay for breakfast including the price of his meal, sales tax, and tip $16.60

A zoologist studied the wild cat population of two islands during a four year span - Meow Island and Purr Island. She collected the following data about the population.
1. How would you describe the growth of each island ?
2. Which do you think will be modeled by a linear function ?
Answer:
Meow Island has a linear function.
Step-by-step explanation:
Meow Island increases by multiply the input by 3 for each coordinate. On the other hand, Purr Island increases by adding 4. Linear functions increase with multiplication, not by addition, and so Meow Island increases linearly.

So, Start with the formula
V= pi ×R² × H
V= pi × 9² × 2
V= pi × 81 × 2
V = 162 pi in³
Then ×2 = 342 in³
required volume =162π or 508.94or 509in³
Answer:

What is the diameter of the circle?
Answer:
around 36 is the diameter
Step-by-step explanation:
C=2Pir or pi*d
113.04=pi*d
113.04/pi=d
d≈36
give me brainliest[tex]≈[/tex]
36 units is the diameter of the circle.
What is Perimeter?The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.
We can use the formula for the circumference of a circle, C = πd,
where C is the circumference and d is the diameter.
Substituting the given value, we have:
113.04 = πd
To solve for d, we can divide both sides by π:
d = 113.04/π
Using a calculator to evaluate this expression, we get:
d ≈ 36
Therefore, the diameter of the circle is approximately 36 units.

Danny flips four well-balanced coins. What are the odds that two of the coins will land ‘heads’ up?
Answer:
0.375 = 37.5% probability that two of the coins will land ‘heads’ up
Step-by-step explanation:
For each coin, there are only two possible outcomes. Either it lands heads, or it lands tails. The probability of a coin landing heads is independent of any other coin. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Four well-balanced coins.
This means that [tex]n = 4, p = 0.5[/tex]
What are the odds that two of the coins will land ‘heads’ up?
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.5)^{2}.(0.5)^{2} = 0.375[/tex]
0.375 = 37.5% probability that two of the coins will land ‘heads’ up
The population of China was about 1.39 billion in the year 2013with an annual growth rate of about 0.6\% . Find an equation P(t) that represents the growth function for China. Write your answer in the form a * (b) ^ 2 in billions Provide your answer below:
Answer: 1.39(1.006)^t
Step-by-step explanation:
The equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.
What is a Function ?A statement that relates two unknown parameters such that one is dependent on the other is called a function.
It is given that
Initial population = 1.39 billion in 2013
Growth Rate = 0.6%
Let a represent the initial population
b is the growth rate
and 2 be the elapsed year from 2013
and let the population at any given year is P(t)
Then the equation formed is
P(t) = a * bⁿ
P(t) = 1.39 * ( 1.006)ⁿ
Therefore the equation P(t) that represents the growth function for China is P(t) = 1.39 * ( 1.006)ⁿ.
