Help please i dont know what to do?

This is a tricky question but my best guess is .5 or 1/2 a foot per minute. I divided 3-8 as a decimal and added one/4th part to it to be a full minute.

The answer to this question is 0.9

We know that

sequre of 9 is equal to 81  as [tex]9^2 = 81[/tex]

Then sequre of 0.9 will be

[tex]0.9^2 = 0.81[/tex]

So,

b = [tex]\sqrt{ 0.81}[/tex]

b = [tex]\sqrt{ 0.9^2}[/tex]

Exponent and square root cancel out each other

So, the answer is 0.9.

the answer is a, 600

What is [tex]7\dfrac{3}{8}[/tex] of [tex]1600[/tex] ?

You must multiply [tex]1600[/tex] by [tex]7\dfrac{3}{8}=\dfrac{7\cdot8+3}{8}=\dfrac{59}{8}[/tex].

[tex]1600\cdot\dfrac{59}{8}=200\cdot\dfrac{59}{1}=200\cdot59=11800[/tex]

Answer:

Option B.

Step-by-step explanation:

(f-g)(x) = f(x)-g(x)

          = (5x²-3) - (x²-4x-8)

          =5x²-3 -x² +4x +8       ( - sign outside will multiply each sign inside)

         =4x² +4x + 5

The cost is $395.  You are trying to find n in 24n + 35.

Set C = 395.

You get 395 = 24n + 35.

Solve for n by first subtracting 35 from both sides of the equation:

395 - 35 = 360.

24n + 35 - 35 = 24n.

Now you have 360 = 24n.  Divide both sides by 24 to get:

15 = n.

So, 15 birthday cakes are made when the cost is $395.

The Number of cakes that can be made with $395 is 15.

The cost function :

C(n) = 24n + 35

The number of cakes, n that can be made with $395:

Substitute, C(n) = 395 into the equation :

395 = 24n + 35

24n = 395 - 35

24n = 360

Divide both sides by 24

n = 360 / 24

n = 15

Therefore, 15 cakes can be made with $395

For this case we must clear x from the given equation:

[tex]y = x ^ 2 + 23[/tex]

We passed 23 subtracting the other side of equality:

[tex]y-23 = x ^ 2[/tex]

By definition, [tex]a ^ 2 = b[/tex]is written as [tex]a = +/-\sqrt{b}[/tex]

So, we have:

[tex]x = + / -\sqrt{(y-23)[/tex]

So, the solution of [tex]y = x ^ 2 + 23[/tex] for x is:

[tex]x = + / -\sqrt{(y-23)[/tex]

Answer:

[tex]x = + / -\sqrt{(y-23)[/tex]

Answer:

The given equation is

 →x²=16

→x²-16=0

→(x-4)(x+4)=0

x=4, -4

p=4

q=-4

Option C

A number line is shown from negative 10 to 0 to positive 10. There are increments of 2 on the number line, and all these are increments are labeled. A dot is shown on positive 4, another dot is shown on negative 4, and are labeled as p and q, respectively.

To solve the expression 8.246 minus 5 hundredths, we subtract 0.05 from 8.246, aligning the decimal places, which gives us the final answer of 8.196, accurately rounded to the thousandths place.

To solve 8.246 - 5 hundredths, we need to understand what five hundredths mean. Five hundredths is the same as 0.05. So, the problem now looks like 8.246 - 0.05.

When we subtract these two values, we need to line up the decimal places properly:

Subtracting, we get:

It's important to note that when subtracting values, you must consider the position of the farthest right significant figure. In this case, the least precise number (original number) had its farthest right significant figure in the thousandths place, so our final answer is also rounded to the thousandths place.

ANSWER

The zeros are [tex]x=-5,x=0,x=5[/tex]

EXPLANATION

Given;

[tex]f(x)=x^4-25x^2[/tex].

We can rewrite the function as

[tex]f(x)=x^2(x^2-25)[/tex]

[tex]\Rightarrow f(x)=x^2(x^2-5^2)[/tex]

[tex]\Rightarrow f(x)=x^2(x-5)(x+5)[/tex]

The zeros are found by equating the function to zero.

[tex]\Rightarrow x^2(x-5)(x+5)=0[/tex]

[tex]\Rightarrow (x-5)=0[/tex]

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is [tex]x=5[/tex]

Or

[tex]\Rightarrow (x+5)=0[/tex]

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is [tex]x=-5[/tex]

Or

[tex]\Rightarrow x^2=0[/tex]

This last root has a multiplicity of 2.

That is

[tex]x=0[/tex] repeats two times.

Since the multiplicity is even, the graph touches the x-axis at the point [tex]x=0[/tex].

See graph.

The zeros of the function ƒ(x) = x4 -25x2 are -5, 0, and 5. Each of these zeros has a multiplicity of 1. The graph crosses the x-axis at each of these zeros, indicating odd multiplicities.

The polynomial function given is ƒ(x) = x4 -25x2. In order to find the zeros, you set the function equal to zero and solve for x: 0 = x4 -25x2. This can be rewritten as x2(x2 - 25) = 0. From this, it's clear that x = 0 is a zero of the function. The other zeros can be found by setting x2 - 25 = 0, resulting in x2 = 25, and therefore, x = ±5. So, the zeros are -5, 0, and 5. Each of these zeros has a multiplicity of 1, because the factorization of f(x) doesn't include any squared terms. The graph crosses the x-axis at each of these points, which is characteristic of odd multiplicities.

let L be the length

let W be the width

L = 9 + 2W

since the perimeter = 2L + 2W

Perimeter = 2 x (9 + 2W) + 2W

174 m = 18 + 4W + 2W

174 m = 18 + 6W

6W = 174 - 18

6W = 156

W = 156/6

W = 26

L = 9 + 2W

L = 9 + 2 x 26

L = 9 + 52

L = 61

Therefore, length = 61 m and width = 26 m.

The correct statements are '15 < 700' and '700 = 700'.

In mathematics, we use comparison operators to establish relationships between numbers.

By comparing the given numbers, we see that 15 is less than 700, which makes the correct statement: '15 < 700'. Additionally, the statement '700 = 700' is also correct, as these values are identical and other statements are incorrect.

Answer:

2 1/12

Step-by-step explanation:

Maddie wants her total hours to be 10 1/2. That is, she want the sum of the daily hours to be that value:

... 10 1/2 = 2 1/2 + 2 2/3 + 3 1/4 + (more hours)

Subtracting the contant terms on the right, we can find the value of (more hours).

... 10 1/2 - 2 1/2 - 2 2/3 - 3 1/4 = (more hours)

Doing the subtraction left to right, we have

... 8 - 2 2/3 - 3 1/4 = (more hours)

... 5 1/3 - 3 1/4 = (more hours)

... 2 1/12 = (more hours)

The only subtraction that may require any extra effort is subtracting 1/4 from 1/3.

... (1/3) - (1/4) = (4/12) - (3/12) = (4 -3)/12 = 1/12

If you play with fractions very much, this is a number fact you will have run across before.

Final answer:

To find the value of x, we can use the given equations and the Angle Sum Property of a Triangle. By substituting the known values into the equation (9x-10), we can solve for x.

Explanation:

To find the value of x, we can use the facts given in the question. We know that m<mkl = 83 and m<jkl = 127. We also know that m<jkm = (9x-10). From these facts, we can form two equations:

1. m<mkl = 83

2. m<jkl = 127

Using these equations, we can determine the value of x.

Let's solve the first equation:

1. m<mkl = 83

Since m<mkl = 83 and m<jkl = 127, we can substitute these values into equation (9x-10) according to the Angle Sum Property of a Triangle:

2. 83 + 127 + (9x-10) = 180

Simplifying the equation, we get:

3. 210 + 9x - 10 = 180

Combining like terms, we have:

4. 9x + 200 = 180

Subtracting 200 from both sides, we get:

5. 9x = -20

Dividing both sides by 9, we find:

6. x = -20/9

Therefore, the value of x is -20/9.

Problem

You deposit $2000 into a bank account paying 4.5% simple interest per year. You left the money in for 8 years. How much interest do you get at the end of those 8 years?

Then you add the money you invested to your interest so your answer would be  ' C ',

I think I'm not that great with math but I really hope I helped you .

Answer:

D. $2630

Step-by-step explanation:

Given,

The principal amount, P = $ 2000,

Annual rate of interest, r = 4.5 % ,

Thus, the interest for 7 years,

[tex]I=\frac{P\times r\times 7}{100}[/tex]

[tex]=\frac{2000\times 4.5\times 7}{100}[/tex]

[tex]=\frac{63000}{100}[/tex]

[tex]=630[/tex]

Hence, the amount after 7 years or at the beginning of the 8th year is,

[tex]A=P+I=2000+630=\$ 2630[/tex]

Option 'D' is correct.

[tex]f(x)=2x^2+5\sqrt{x-2}\\\\f(3)\to\text{put the value of x = 3 to the equation of the function}\\\\f(3)=2(3^2)+5\sqrt{3-2}=2(9)+5\sqrt1=18+5(1)=18+5=23[/tex]

Your answer would be 4379 members because at the very beginning you had started off with 4372 members, however as the months go by changes happen. On october, it changed by -10, meaning that 10 students left the school meaning 4372-10=4362 members remaining. Then there's november with -8, so you subtract 8 from your new total 4362-8=4354. Then december comes, and this time it's a positive number, so you have to add 23 to 4354, giving you a new total of 4377. Then there's january, and its back to a negative number so you subtract 12 from 4377, 4377-12=4365. Then february comes and it's a change of a positive number, so you add 3 to the 4365, giving you 4368. And then finally by march, it's another positive number so you add 11 to your total, giving you 4379 students which are now at school. So basically if it's a negative change, subtract from the total, and if it is a positive, add to it. And you have to continue with the total that you got from the previous change that you did. Hope this was helpful

basically you start with 4372 the table shows what happens during the school so after September you go to October which is -10 so you end up with 4362 then, November which is -8 so you get 4354 then in December you have +23 which makes 4377 then in January you have -12 which makes 4365 then in Feburary you have +3 which makes 4368 then in march you have +11 so 4379 so
