Step-by-step explanation:
That's what I would say, at least.
the graph of f(x) shown below has the same shape as the graph of g(x)=x^2 but is shifted down 5 units and to the left 4 units (thank you)
Answer:
D. [tex]F(x)=(x+4)^2-5[/tex]
Step-by-step explanation:
The parent function is [tex]G(x)=x^2[/tex].
This function has its vertex at the origin (0,0).
When this function is shifted down 5 units and to the left 4 units, then its new vertex will be at (-4,-5)
The vertex form of the equation is given by;
[tex]F(x)=a(x-h)^2+k[/tex] where (h,k)=(-4,-5) is the vertex and a=1 because of the parent function.
Hence its equation is
[tex]F(x)=(x+4)^2-5[/tex]
Answer:
Option C
Step-by-step explanation:
A function g(x) = x² has been given as the parent function.
This function then shifted 5 units down.
Translated function formed will be f(x) = x² - 5
Further this graph has been shifted 4 units to the left then the function will become
f(x) = [x - (-4)]² - 5
f(x) = (x + 4)² - 5
Therefore, option C is the answer.
At a local company, the ages of all new employees hired during the last 10 years are normally distributed. The mean age is 38 years old, with a standard deviation of 10 years. Find the percent of new employees that are no more than 30 years old. Round to the nearest percent.
Answer:
P = 21%
Step-by-step explanation:
We look for the percentage of employees who are not more than 30 years old.
This is:
[tex]P = \frac{x}{n} *100\%[/tex]
Where x is the number of new employees who are not over 30 years old and n is the total number of new employees.
We do not know the value of x or n. However, the probability of randomly selecting an employee that is not more than 30 years old is equal to [tex]P = \frac{x}{n}[/tex]
Then we can solve this problem by looking for the probability that a new employee is not more than 30 years old.
This is:
[tex]P(X< 30)[/tex]
Then we find the z-score
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
We know that:
μ = 38 years
[tex]\sigma = 10[/tex] years
So
[tex]Z = -0.8[/tex]
Then
[tex]P (X<30) = P (\frac{X- \mu}{\sigma} < \frac{30-38}{10})\\\\P (X<30) = P(Z<-0.8)[/tex]
By symmetry of the distribution
[tex]P(Z<-0.8)=P(Z>0.8)[/tex]
Looking in the normal standard tables
[tex]P(Z>0.8)=0.211[/tex]
Finally P = 21%
A 150lb woman receives 24 grams of medicine. How many grams would a 120lb woman get
Answer:
19.2 grams
Step-by-step explanation:
We can solve the problem via ratio and proportions or simply through cross-multiplication;
we can formulate the following proportions;
(medication/weight) = constant
24/150 = x/120 = constant
where x is the quantity of medication for the 120 lb woman.
solving for x yields;
x = (24/150)*120
x = 19.2 g
Answer:
The correct answer is 19.2 grams
Step-by-step explanation:
It is given that, a 150lb woman receives 24 grams of medicine
To find the amount of medicine
150lb woman receives 24 grams
From the given information we can write,
1lb woman receives 24/150 grams
120lb woman receives = (24/150) * 120
= 19.2 grams
Therefore 120lb woman get 19.2 grams
The correct answer is 19.2 grams
Given these two terms in a geometric sequence, find the recursive formula.
a1=4
a6=31104
Answer:
[tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]
Step-by-step explanation:
Step 1. Determine the common ratio
The formula for the nth term of a geometric sequence is
aₙ = a₁rⁿ⁻¹
Data:
a₁ = 4
n = 6
a₆ =31 104
Calculation:
31 104 = 4r⁵
r⁵ = 7776
[tex]r = \sqrt [5]{7776}[/tex]
r = 6
aₙ = 4(6)ⁿ
Step 2. Determine the recursive formula.
aₙ = 4(6)ⁿ
aₙ₋₁ = 4(6)ⁿ⁻¹
[tex]\dfrac{a_{n}}{{a_{n-1}}} = \dfrac{4(6)^{n} }{4(6)^{n-1}} = 6\\\\a_{n} = 6a_{n-1}[/tex]
The recursive formula for the series is [tex]\boxed{ a_{n} = 6a_{n-1}}[/tex]
A 24-foot wire connects the top of an antenna to a point on the ground. If the antenna is 20 feet high, how far from the base of the antenna is the wire fixed to the ground?
Answer: 179
Answer:
The answer is 176
Step-by-step explanation:
The answer is the square root of one hundred seventy-six feet.
The height of the antenna and the length of the wire form two sides of a right triangle. The distance from the base of the antenna to the point at which the wire is fixed to the ground forms the other leg.
The Pythagorean Theorem states that a squared plus b squared equals c squared, where a and b are the lengths of the legs of a right triangle and c is the length of the hypotenuse.
Let g equal the length in feet of the unknown leg.
First, apply the Pythagorean Theorem, and substitute twenty-four feet for the length of the hypotenuse and twenty feet for one of the legs.
Next, we square twenty-four and twenty.
Then, subtract four hundred from both sides to get one hundred seventy-six equals g squared.
Finally, take the square root of both sides to get the square root of one hundred seventy-six equals g.
So the distance from the base of the antenna to the point at which the wire is fixed to the ground is the square root of one hundred seventy-six feet.
(13x+7)=(8x+27) like equations yk
Hey there! :)
(13x + 7) = (8x + 27)
We're trying to find x, so we must isolate it.
We can start by subtracting 8x from both sides.
13x - 8x + 7 = 8x - 8x + 27
Then, subtract 7 from both sides.
13x - 8x + 7 - 7 = 8x - 8x + 27 - 7
Simplify!
5x = 20
Divide both sides by 5.
5x ÷ 5 = 20 ÷ 5
Simplify.x = 4
~Hope I helped!~
Answer:
[tex]x = 4[/tex]
Step-by-step explanation:
[tex]13x + 7 = 8x + 27[/tex]
Take 8x to the left side and 7 to the right.
[tex]13x - 8x = 27 - 7[/tex]
Combine like terms.
[tex]5x = 20[/tex]
Divide both sides by 5.

Complete the steps to factor 12x3-9x2+8x-6 by grouping
Answer:
(4x−3)(3x²+2)
Step-by-step explanation:
Factor 12x3−9x2+8x−6
12x3−9x2+8x−6
=(4x−3)(3x2+2)
The factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).
To factor the expression 12x³ - 9x² + 8x - 6 by grouping, we can group the terms in pairs and factor out the common factors.
Step 1: Group the terms in pairs
(12x³ - 9x²) + (8x - 6)
Step 2: Factor out the greatest common factor from each pair
3x²(4x - 3) + 2(4x - 3)
Step 3: Notice that both terms now have a common factor of (4x - 3)
(3x² + 2)(4x - 3)
Therefore, the factored form of the expression 12x³ - 9x² + 8x - 6 by grouping is (3x² + 2)(4x - 3).

A garden table and a bench cost $741 combined. The garden table costs $91 more than the bench. What is the cost of the bench?
Answer:
bench: $416; table: $325.
Step-by-step explanation:
Let t and b represent the costs of the table and bench respectively. Then:
t + b = $741, and t = b + $91.
Substituting b + $91 for t in the first equation, we get:
b + $91 + b = $741
Then 2b = $741 - $91, or 2b = $650
Then the bench costs $325 and the table ($325 + $91), or $416.

No solution
Step-by-step explanation:
x² + 3 x + 40 = 0
Answer:
The answers for x^2+3x−40=0 are -8 and 5.
Step-by-step explanation:
For this problem, we are able to factor. Since 8 and 5 are both factors of 40, and since 8-5=3, we will use 8 and 5 in our binomial equation:
(x+8)(x−5)=40.
Just to prove that this is correct, let's multiply the two together: x^2−5x+8x−40=x^2+3x−40.
From here, we can use the zero product property to get our answers: x+8=0,x−5=0.
Subtract 8 from the first equation and subtract 5 from the second equation to get our answers, -8 and 5.

Find the perimeter of a field that has length 2/x + 1 and width 5/x^2 -1.
A) 2x + 3/(x + 1)(x - 1)
B) 10/(x + 1)(x - 1)
C) 7/(x + 1)(x - 1)
D)4x + 6/(x + 1)(x - 1)
Answer:
D)4x + 6/(x + 1)(x - 1)
Step-by-step explanation:
A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle
[tex]p=2(l+w)[/tex]
where
[tex]p[/tex] is the perimeter
[tex]l[/tex] is the length
[tex]w[/tex] is the width
We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so [tex]l=\frac{2}{x+1}[/tex] and [tex]w=\frac{5}{x^2-1}[/tex].
Replacing values:
[tex]p=2(l+w)[/tex]
[tex]p=2(\frac{2}{x+1} +\frac{5}{x^2-1})[/tex]
Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula [tex]a^2-b^2=(a+b)(a-b)[/tex] where [tex]a[/tex] is the first term and [tex]b[/tex] is the second term. We can infer that [tex]a=x^2[/tex] and [tex]b=1^2[/tex]. So, [tex]x^2-1=(x+1)(x-1)[/tex]. Replacing that:
[tex]p=2(\frac{2}{x+1} +\frac{5}{x^2-1})[/tex]
[tex]p=2(\frac{2}{x+1} +\frac{5}{(x+1)(x-1})[/tex]
We can see that the common denominator of our fractions is [tex](x+1)(x-1)[/tex]. Now we can simplify our fraction using the common denominator:
[tex]p=2(\frac{2(x-1)+5}{(x+1)(x-1)} )[/tex]
[tex]p=2(\frac{2x-2+5}{(x+1)(x-1)} )[/tex]
[tex]p=2(\frac{2x+3}{(x+1)(x-1)} )[/tex]
[tex]p=\frac{4x+6}{(x+1)(x-1)} [/tex]
We can conclude that the perimeter of the field is D)4x + 6/(x + 1)(x - 1).

What is the probability (rounded to the nearest whole percent) that a randomly selected college student has a tablet but not a smartphone?
A.) 20%
B.) 5%
C.) 17%
D.) 67%
Answer:
C) 17%
Step-by-step explanation:
Table: has tablet | no tablet | total
has phone | 25 65 90
no phone | 20 10 30
total | 45 75 120
No tablet total: 120 - 45 = 75
No phone total: 120 - 90 = 30
No tablet phone: 75 - 10 = 65
No phone tablet: 30 - 10 = 20
Both: 45 - 20 = 90 - 65 = 25
-------------------------------------------------------------------------
So out of 120 students, 20 of them will have a tablet but no phone. 20/120 = 1/6 = 0.16666... ≈ 17%
