To write the equation in LaTeX in form y = ab^x  or [tex]ab^x[/tex] for y = abx .........(1)

(a) LaTeX: y=3\sqrt{4^{2x}}  y = 3 4 2 x can be written in mathematical form as

[tex]y=3\sqrt{4^{2x}}[/tex] ; y = 342x

on comparing with equation (1) we get a =3 and b =4

⇒y = 34^x or [tex]34^x[/tex]

(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as

[tex]y=\frac{\sqrt[3]{5^{3x}}}{2}[/tex] ; y = 342x

on comparing with equation (1) we get a =0.5 and b =5

⇒y = [tex]\frac{1}{2}5^x[/tex]

(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as

[tex]y=8^{x+2}[/tex]

on comparing with equation (1) we get a =64 and b =8

y = [tex]64 . 8^x[/tex]

(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}  can be written in mathematical form as

[tex]y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}[/tex] = [tex]3^{x+1}[/tex] = [tex]3 . 3^x[/tex]

on comparing with equation (1) we get a =3 and b =3

y = [tex]3 . 3^x[/tex]

Answer:

Two mathematical terms are alike (not alike) , if they have same (different) variables & in same (different) mathematical treatment.

Step-by-step explanation:

Two mathematical terms are alike, if they have same variables & in same mathematical treatment.

Eg : 2 xy , 5 xy. These are alike, as they have product of x & y being multiplied with constants.

They can be added, subtracted by adding or subtracting their constants.

2 xy + 5 xy =  (2 + 5) xy = 7 xy

5 xy - 2 xy =  ( 5- 2 ) xy = 3 xy

80 %

Step-by-step explanation:

Step one:

Given data

We are told that Oscar made 28 out of 35 field goals during football practice.

Required

The percentage accuracy

Step two:

% Accurracy= number of goals/number of practice*100

% Accurracy= 28/35*100

% Accurracy=0.8*100

% Accurracy= 80%

Hence the percentage that he made is 80 %

Answer:

The required graph is shown below.

Step-by-step explanation:

Consider the provided equation [tex]y=3x+2[/tex]

We need to draw the graph of the equation.

Put x=0 in the above equation.

[tex]y=3(0)+2[/tex]

[tex]y=2[/tex]

The coordinate is (0,2).

Put y=0 in the given equation.

[tex]0=3x+2[/tex]

[tex]-2=3x[/tex]

[tex]x=\frac{-2}{3}[/tex]

The coordinate is ([tex]\frac{-2}{3}[/tex],0).

Now draw the graph by using the above coordinates.

The required graph is shown below.

Answer:

Thw answer is 32

Step-by-step explanation:

Answer:

She should sell 32 plans.

Step-by-step explanation:

If she earns 7.5% of $1,500 on each plan she sells, that mean she makes $112.50 on each plan sold. Divide $3,600 by that and you get how many plans she should sell to make $3,600 this month. (3600 / 112.5 = 32)

Answer:

The first brother is 16, the second brother is 8 and the third brother is 4.

Step-by-step explanation:

Since the sum of all the brothers  is 28, that means the cap of how old the oldest can be is 28. I just stated with numbers less then 28 that were dividable by two which means all the numbers had to be. So 16 for the first, 8 for the second and 4 for the youngest is the right answer I hop.

B. A spinner divided into 5 congruent sectors, spun 4 times

Have a good day

The correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given that, A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks.

The correct spinner to use among the 4 should have a probability of winning of 80%, similar to what the owner has found out. So, we must calculate the probability of each spinner.

1. Spun 3 times, and chance of winning is 1 in 5, therefore P = (3) (1/5) = 0.6 = 60%

2. Spun 4 times, and chance of winning is 1 in 5, therefore P = (4) (1/5) = 0.8 = 80%

3. Spun 3 times, and chance of winning is 1 in 2, therefore P = (3) (1/2) = 1.5 = 150%

4. Spun 4 times, and chance of winning is 1 in 2, therefore P = (4) (1/2) = 2 = 200%

We can see that there is only 1 choice that has 80% probability,

Hence, the correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”

Answer:

The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)

Step-by-step explanation:

Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).

Answer:

I would need to know the number of radios she made each day.

Step-by-step explanation:

lets say she assembled 2 radios a day, which means we would do 0.54 x 2 (that would be 1.08) and then times it by 6 ***not incuding sunday***

you would get $6.48

then for sunday we would do 0.62 x 2 (that would be 1.24) .

now we add 6.48 and 1.24 to get $7.72 a week.

Answer:

3,4,5

Step-by-step explanation:

Here, we want to select the set that could work and the sides of a right angled triangle

the correct answer is 3,4,5

These set are called a Pythagorean triple

This is because adding the square of the two smaller number will give the square of the largest number

What we are saying here is that by adding the square of 3 and 4, we get the square of 5 which illustrates that Pythagoras theorem works for the set

Answer:

B) x ≥ 8

Step-by-step explanation:

x represents the number of dollars that Anna has.

If Anna has at least 8 dollars, she could have 8 or any number greater than 8 dollars. Anna could have 8, 9, 10, 11... etc. dollars.

This means that x is equal to or greater than 8.
