If f(x)=6x+7 and g(x)=x^2-4 find value of g(-4t)

Answers

Answer 1

The final value of g(-4t) is [tex]16t^2 - 4.[/tex]

To find the value of g(-4t) with [tex]g(x) = x^2 - 4[/tex], substitute -4t into the function

The task is to find the value of g(-4t) when given that [tex]g(x) = x^2 - 4.[/tex]

To solve this, we simply replace x with -4t in the function g(x).

So, [tex]g(-4t) = (-4t)^2 - 4.[/tex]

Squaring -4t gives us [tex]16t^2[/tex], so the expression simplifies to [tex]16t^2 - 4.[/tex]

The final value of g(-4t) is [tex]16t^2 - 4.[/tex]

Answer 2

The values are: f(-3) = -11, f(m) = 6m + 7, f(r-2) = 6r - 5, g(5) = 21, and g(a) + 9 = a^2 + 5.

f(-3): Replace x with -3 in f(x) = 6x + 7
f(-3) = 6(-3) + 7 = -18 + 7 = -11f(m): Replace x with m in f(x) = 6x + 7
f(m) = 6m + 7f(r-2): Replace x with r-2 in f(x) = 6x + 7
f(r-2) = 6(r-2) + 7 = 6r - 12 + 7 = 6r - 5g(5): Replace x with 5 in g(x) = x^2 - 4
g(5) = 5^2 - 4 = 21g(a) + 9: Replace x with a in g(x) = x^2 - 4 and add 9
g(a) + 9 = a^2 - 4 + 9 = a^2 + 5

Complete question is:

If f(x)=6x+7 and g(x)=x^2-4, find each value.

1.) f(-3)

2.) f(m)

3.) f(r-2)

4.) g(5)

5.) g(a)+9

The selling price of an item is $520. After 6 months of not selling, it is marked down by 20%. After another another 6 months of not selling, it is further marked down by 30%. Find the sale price after both markdowns. Could you just tell me the steps and maybe give an example to this? Thank you.

Answers

Final answer:

To find the sale price after both markdowns, first apply a 20% markdown to the selling price and then apply a 30% markdown to the resulting price.

Explanation:

To find the sale price after both markdowns, first apply the first markdown of 20%. To do this, multiply the selling price by 0.80 (1 - 0.20), since a 20% markdown is equivalent to selling at 80% of the original price. So, the price after the first markdown is $520 x 0.80 = $416.

Next, apply the second markdown of 30% to the price after the first markdown. Multiply $416 by 0.70 (1 - 0.30) to find the final sale price. $416 x 0.70 = $291.20.

Therefore, the sale price after both markdowns is $291.20.

Brandon bikes 8 and 1/2 miles in 1/2 hour. To find out how far he bikes in 1 hour, we need to double the distance, because one hour is twice as long as half an hour.

Miles per hour = Miles in half an hour * 2 = (8 +  1/2) miles * 2

Now, let's perform the multiplication:

8 * 2 = 16

1/2 * 2 = 1

Therefore, 16 + 1 = 17 miles per hour.

Brandon bikes 17 miles in 1 hour. This is the distance he would cover if he continues at the same pace for a full hour.

Notice that we get a 4/4 in the denominator in which case we multiply the two (because they are both denominators:

[tex]\frac{3}{\frac{4}4} } = \frac{3}{16}[/tex]

So, the unit rate is 3/16 lbs/person.

Final answer:

To find the unit rate in pounds per person, divide the total weight of the candy by the number of people. In this case, the unit rate is 3/16 lb per person.

Explanation:

To find the unit rate in pounds per person, we divide the total weight of the candy (3/4 lb) by the number of people (4). This can be represented as 3/4 ÷ 4. To simplify the division, we can multiply the numerator and denominator by 4 to get rid of the fraction. This gives us 3/16 lb per person as the unit rate in pounds per person.

Nicole did an aerobics class and yoga class for at total of 1 hour and 10 minutes. The yoga class was 30 minutes. The yoga class was 30 minutes longer than the aerobics class. How long was each class.

Answers

yoga class was thirty minutes and the aerobics class was 0 minutes.
Final answer:

The aerobics class lasted 20 minutes and the yoga class lasted 50 minutes. This was determined by setting up an equation and solving for the duration of each class, given the total time and the information that the yoga class was 30 minutes longer.

Explanation:

The student is trying to find out how long each class was—Nicole attended an aerobics class and a yoga class for a total of 1 hour and 10 minutes, with the yoga class lasting 30 minutes longer than the aerobics class. To find the answer, we can set up an equation. Let the duration of the aerobics class be x minutes. Therefore, the duration of the yoga class would be x + 30 minutes. According to the question, the total time spent in both classes is 70 minutes (1 hour and 10 minutes).

Now, we can write an equation that represents the total time:

x (aerobics class) + x + 30 (yoga class) = 70 minutes

Combining the x terms we get:

2x + 30 = 70

To find x, we subtract 30 from both sides of the equation:

2x = 40

Dividing both sides by 2 gives us:

x = 20

So the aerobics class lasted 20 minutes, and since the yoga class was 30 minutes longer, it lasted 50 minutes.

Use the magic penny parable to determine how much money you would have after 8 days.

Answers

Final answer:

In the magic penny parable, choosing a penny that doubles in value every day leads to a significant amount of money. After 8 days, you would have 256 pennies.

Explanation:

The magic penny parable is a story that demonstrates the power of compound interest. In the story, a person is given the choice between taking a million dollars or a penny that doubles in value every day for 30 days. By choosing the penny, they end up with over 5 million dollars at the end of 30 days.

To determine how much money you would have after 8 days, we can use the formula for compound interest:

Final amount = Initial amount * (1 + interest rate) ^ number of periods

In this case, the initial amount is 1 penny, the interest rate is 100% (as the penny doubles in value), and the number of periods is 8 days.

Using this formula, the calculation would be:

Final amount = 1 penny * (1 + 1)^8 = 1 penny * 2^8 = 1 penny * 256 = 256 pennies.

Therefore, after 8 days, you would have 256 pennies.

Answers

Number of pencils = P 
Number of students = S 

P / S = 3 
P = 3S 

P = 2S + 10 

3S = 2S + 10 
S = 10 

He has 10 students and 30 pencils
Final answer:

To find the number of students in the group, we can use algebra to solve two equations simultaneously.

Explanation:

Let's solve this problem using algebra. Let's say there are x students in the group.

If Mr. Chan gives each student 2 pencils, he will have 10 pencils left. This can be expressed as the equation 2x + 10 = P, where P represents the total number of pencils Mr. Chan bought.

If Mr. Chan gives each student 3 pencils, he will have no pencils left. This can be expressed as the equation 3x = P.

Solving these two equations simultaneously, we can find the value of x, which represents the number of students in the group.

Points S and T are midpoints of the sides of triangle FGH

what is GF ?

Answers

Answer:

Using triangle similarity theorems, GF is 16 cm (fourth option)

Step-by-step explanation:

If points S and T are midpoints of the sides of triangle FGH, the segment ST is parallel to the side GF and the triangles FGH and TSH are similars, and their corresponding sides must be proportionals, then:

GF/ST=FH/TH=GH/SH

TH=6 cm→FT=6 cm, because T is the midpoint of side FH, and:

FH=2 TH = 2 FT =2 (6 cm)→FH=12 cm

GS=4 cm→SH=4 cm, because S is the midpoint of side GH, and:

GH=2 GS = 2 SH =2 (4 cm)→GH=8 cm

ST= 8 cm

Replacing the known values in the proportion:

GF/ST=FH/TH=GH/SH

GF/(8 cm)=(12 cm)/(6 cm)=(8 cm)/(4 cm)

GF/(8 cm)=2=2

GF/(8 cm)=2

Solving for GF: Multiplying both sides of the equation by 8 cm:

(8 cm) [GF/(8 cm)]=(8 cm)(2)

GF=16 cm

If Points S and T are midpoints of the sides of triangle FGH, the measure of the length GF is 16cm. Option D is correct

To get the length of Gf, we will need to use the similarity theorem of a triangle as shown:

HT/TS = HF/Gf

From the diagram, we have the following:

HT = FT = 6cm

ST = 8cm

Substitute the given parameters into the formula to have:

6/8 = 6+6/GF

6/8 = 12/GF

6FG = 96

FG = 96/6

FG = 16cm

Hence the measure of the length GF is 16cm

Can someone explain multiplicity of a zero?

Answers

The multiplicity is the number of "times" a zero exists.

So, if the Function would be (x-3)(x-3)(x-1)=0
The zeros would be 3 (with a multiplicity of 2), and 1.

So any time you see the same factor more than once, it has a multiplicity greater than 1.

Multiplicity refers to the exponents of the factors.  For example:

x³(x + 1)(x + 2)²(x² + 1) = 0

x:        has a multiplicity of 3 because its exponent is 3

x + 1:    has a multiplicity of 1 because its exponent is 1:  (x + 1)¹

x + 2:    has a multiplicity of 2 because its exponent is 2

x² + 1:    has a multiplicity of 1 because its exponent is 1: (x² + 1)¹

A fast food restaurant sold 35 burgers with cheese if the ratio sold with cheese compared to without cheese was 7:3 how many burgers did they sell total

Answers

A 7 to 3 ratio means that for every time they sell 7 burgers with cheese sold, they also sold 3 burgers without cheese.

So you solve this by figuring out how many times they sold 7 burgers and then you use that number to find your answer.

35 / 7 = 5

So they sold 7 burgers 5 times.
So that means that they also sold 3 burgers 5 times since for every 7 burgers with cheese they sell 3 burgers without cheese.

So 3 * 5 = 15

You then add your two numbers and you have your answer.

35 burgers with cheese + 15 burgers without cheese = 50 burgers total.

Final answer:

To find the total number of burgers sold by the fast food restaurant, calculate the burgers sold without cheese using the ratio provided and then find the total by adding burgers with cheese and without cheese.

Explanation:

To find out how many burgers the fast food restaurant sold in total, we first need to determine the number of burgers sold without cheese. Since the ratio of burgers sold with cheese to without cheese is 7:3, we can calculate that for every 7 burgers sold with cheese, 3 were sold without cheese. Therefore, 35 burgers with cheese corresponds to 35 / 7 * 3 = 15 burgers without cheese. Hence, the total number of burgers sold is 35 (with cheese) + 15 (without cheese) = 50 burgers.
