The function h(x) is a translation of 4 units to the left, so the correct options is B.
h(x) = √(x + 4)
What is the rule for function h(x)?We know that h(x) is a transformation on the parent square root function:
f(x) = √x
If we look at the graphs, we can see h(x) is translated 4 units to the left.
Now, for a function f(x), we define a horizontal translation of N units as:
h(x) = f(x + N)
if N < 0, the translation is to the right.
if N > 0, the translation is to the left.
In this case we have a translation of 4 units to the left, then N = 4, so we can write:
h(x)= f(x + 4)
Replacing the function f(x) we get:
h(x) = √(x + 4)
So the correct option is B.

the number of people infected with coronavirus doubles every 3.3 days. how many days does it take for the u.s. to go from one case (patient zero) to all 330,000,000 americans being infected.
Answers
It will take 96.7 days for the whole US population to get infected.
Given information;
The number of people infected with coronavirus doubles every 3.3 days as following;
1 → 2 → 4 → 8 → 16 → 32 → 64 → . . . . . . . . . . . . → 333,000,000
Let 'x' denotes number of 3.3 days passed the for cases 333,000,000.
⇒ [tex]2^x = 333,000,000[/tex]
For the above equation applying log on both sides. we get;
x(In 2) = In (330,000,000)
x = In (330,000,000)/(In 2)
x = 28.3
Therefore;
So, total no. of 3.3 days passed = 1 + x
= 1 + 28.3
= 29.3
And number of days for 1 to 330,000,000 = 29.3 * 3.3 days
= 96.7 days
Hence, it will take 96.7 days to infect the total population in US.

Step-by-step explanation:
so in y=mx+b form.
m=slope b=y-int
Subtract 5 from both sides to isolate y on a side.
4x-6=3y
Divide both sides by 3 to isolate y on one side.
(4/3)x-2=y
y=(4/3)x-2
m=4/3

Nelson’s birthday party will be at the skating rink. The cost for each person is $ 25 . The cost of the room for the party is $ 50 . The function C ( x ) = 25 x + 50 models the total cost, C , where x is the number of people at the party. What is the maximum number of people who can be at the party for a budget of $ 600 ?
Answers
Answer:
24 people
Step-by-step explanation:
600 = 25x + 50 Subtract 50 from both sides of the equation
550 = 25x Divide both sides by 25
24 = x
Answer: x = 22
Step-by-step explanation:
We need to use trial and error for this.
20 - 25 seems like a reasonable range to substitute x with.
C(20) = 25(20) + 50
C(20) = 500 + 50
C(20) = 550.
This means that 20 is not the answer. Let's try 21.
C(21) = 25(21) + 50
C(21) = 525 + 50
C(21) = 575.
This means that 21 is also not the answer. let's try 22.
C(22) = 25(22) + 50
C(22) = 550 + 50
C(22) = 600.
This means that 22 is the maximum number of people for a budget of $600.
x = 22
. A bag of marbles contains a ratio of 4 red marbles to 13 more blue marbles than
red marbles. If there are 51 blue marbles, how many red marbles are in the
bag?
Answers
The number of red marbles in the bag is 12.
We are given a bag. The bag contains two types of marbles. There are red and blue marbles in the bag. The ratio of marbles is four red marbles to thirteen more blue marbles than red marbles. Let the ratio of the number of red marbles to that of blue marbles be denoted by the variable "r".
r = 4/(13 + 4) = 4/17
The number of red marbles and blue marbles in the bag is 4x and 17x, respectively, where "x" is a variable. We know that the number of blue marbles in the bag is 51. We can write the following equation to find the value of "x".
17*x = 51
x = 51/17 = 3
Hence, the number of red marbles is 4x = 4*3 = 12.

Answers
TThe 95% confidence interval for the mean spent on books at this university is (160.711, 179.289).
In the given question we have to find the 95% confidence interval for the mean spent on books at this university.
A sample of 50 students was taken from the local university.
So n=50
These students spent an average of $170 on books this semester, with a standard deviation of $25.50.
So x=$170 and σ = $25.50
So the 95% confidence interval for the mean spent on books at this university.
CI=x ± [tex]z_{\alpha /2}[/tex]× σ/√n
Now finding the value of [tex]z_{\alpha /2}[/tex] for 99%=0.99 confidence interval.
[tex]\alpha[/tex] =1−0.99 = 0.01
[tex]\alpha[/tex]/2 = 0.01/2 = 0.005
[tex]z_{\alpha /2}=z_{0.005}[/tex]
[tex]z_{\alpha /2}[/tex] = 2.576
The z critical value at 99% confidence interval is 2.576.
Putting the value
CI=170 ± 2.576× 25.50/√50
CI=170 ± 2.576× 25.50/7.071
CI=170 ± 2.576×3.606
CI=170 ± 9.289
CI=(170 − 9.289, 170 + 9.289)
CI =(160.711, 179.289)
Hence, the 95% confidence interval for the mean spent on books at this university is (160.711, 179.289).

What is a budget?A budget is an estimate of revenue and expenses for a given period of time that is usually compiled and re-evaluated on a regular basis. A budget expresses intended expenditures as well as recommendations for how to meet them with resources.
Saving is the portion of one's income that is not spent on current expenses. In other words, it is money set aside for future use rather than being spent immediately. An expense is a cost incurred by businesses in the course of their operations. Wages, salaries, maintenance, rent, and depreciation are expenses.
In this case, the way to reduce the budget is illustrated.

Write and solve an inequality which can be used to determine vv, the number of visits Nachelle can make to earn her first free movie ticket.
Answers
Step-by-step explanation:
#=number
Identify what is in the inequalityNachelle gets 50 points when signing up: 50+#x=#
Nachelle earns 12.5 points for each visit: 50+12.5x=#
Nachelle need at least 170 points: 50+12.5x=170
Now you have your inequality, solve.Subtract 50 from both sides: 50-50+12.5x=170-50
50-50 cancel out so now your left with 12.5x=170-50
Subtract the 170 and 50: 12.5x=120
Divide 12.5 from both sides: 12.5x÷12.5=120÷12.5
12.5x÷12.5 cancel out so the inequality is now x=120÷12.5
Divide 120 and 12.5: x=9.6

explanation :
not a whole number bc it’s negative
not irrational because it’s rational
not natural because it’s negative
Answer:
Integer, Rational, Real
Step-by-step explanation:
Let's go through and define what each of these are:
Integer:
An integer is any number (including zero) that is positive or negative. Please note that it cannot be a decimal / fraction.
-1 is a whole, negative number. So, it is an integer.
Rational:
A rational number is any number that can be written as a ratio of 2 numbers. Ex: 1.5 can be 3/2
-1 can be written as -1/1, so it is a rational number.
Real
A real number is *any* number that is not imaginary (the number i is imaginary. i is [tex]\sqrt{-1}[/tex])
-1 has no i so it is a real number
Irrational
An irrational number is any number with a radical at it's end. Ex: 3 [tex]\sqrt{5}[/tex], and [tex]2\sqrt{2}[/tex]
-1 has no radical attached to it, so it is not an irrational number.
Whole:
A whole number is any number that has no decimal and is positive (though zero is included)
-1 has no negative, but is a negative number so it would not be counted as a whole number.
Natural:
Natural numbers were always confusing to me, but I hope this will help you. A natural number is any positive number starting at 1, and going forever. They always increase in a multiple of 1. Examples of natural numbers: 1, 2, 3, 4... It is called a natural number, because counting in multiples of ones is natural to us, like counting the amount of apples in a basket.
-1 is a negative number, so doesn't qualify for the characteristics of a natural number.
Let's go back through all of these explanations and see which ones we said -1 is:

What number needs to be added to this set of numbers so the mean is 6? {3,4,7}
Answers
The finalized set is { 3 , 4 ,7 , 10 }
How is mean calculated ?Only numerical variables, whether continuous or discrete, can be used to calculate the mean. It is calculated by merely dividing the total number of values in a data set by the sum of all the values in the data set.
The given set is {3,4,7}
3 + 4 + 7 =14
To calculate the mean we divide the sum by the number of numbers present
So we must add 10
because if we add 10 to the set we get
3 + 4 + 7 + 10= 24
Thus the mean = [tex]\frac{24}{4}[/tex]
When we divide these two numbers we get :
mean = 6
Thus the finalized set is { 3 , 4 ,7 , 10 }

Answers
At Letter2go, Betsie can purchase the 250 envelopes. As an example, 250 envelopes cost £31.9 in the Letter2go store but £33.17 in the Value World store.
What is an Expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations.
From Letters 2 go:
Pack of 25 envelopes for £3.19
If we look at the price of envelopes at shop 1, which is Value World,
The cost of a pack of 10 envelopes is £1.99.
Also, buy 2, get one is free
Which means that 1 pack = £1.99
2 packs = 2×£1.99 = £3.98
Also, with 2 packs Betsie get 1 pack free
So, Betsie gets 3 packs for £3.98.
1 pack = 10 envelopes
3 packs = 30 envelopes.
Hence,
In shop Value World:
30 envelopes = £3.98
1 envelope = £3.98/30
250 envelopes = (3.98/30)×250
So, 250 envelopes will cost £33.17 in Shop Value World.
From shop Letter 2 go:
25 envelopes = £3.19
1 envelope = £3.19/25
250 envelopes = (3.19/25)×250
Therefore, 250 envelopes in Store Letter 2 go should cost £31.9.
