3 x 5 (0 + 2)-4 simplify

Answer:

y + 2 = 23(x - 3)

Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 23 and (a, b) = (3, - 2), hence

y + 2 = 23(x - 3) ← equation in point-slope form

Answer:

-2b/(a-b)

Step-by-step explanation:

1− (a+b/a−b)

We need to get a common denominator of a-b

1 = (a-b)/(a-b)

Replace 1 with (a-b)/(a-b)

(a-b)/(a-b) - (a+b)/(a-b)

Put over the common denominator

(a-b) - (a+b)

Answer:

The annual percentage yield is 6.609%

Step-by-step explanation:

Let's assume

amount invested=$1

so, P=1

APR of 6.4% compounded daily

so, r=6.4%=0.064

n=365

t=1

now, we can use formula

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

now, we ca plug values

[tex]A=1(1+\frac{0.064}{365})^{365\times 1}[/tex]

we get

[tex]A=1.06609[/tex]

now, we can find APY

[tex]APY=\frac{A-P}{P}\times 100[/tex]

now, we can plug values

[tex]APY=\frac{1.06609-1}{1}\times 100[/tex]

we get

APY is 6.609%

Answer:

The annual percentage yield is 6.609%.

Step-by-step explanation:

The annual percentage yield is calculated by:

APY = [tex](1+\frac{r}{n} )^{n} -1[/tex]

where r is the percentage rate and n refers to the number of times compounded.

So, r = [tex]\frac{6.4}{100}[/tex] = 0.064

Since the APR is compounded daily,

n = 365

Now,

APY = [tex](1+\frac{0.064}{365} )^{365} -1[/tex]

= 6.609% approximately

Answer:

Step-by-step explanation:

There are several ways in which you could do this.  

One involves finding the x- and y-intercepts, plotting them and drawing a straight line through them.  Starting with 4x + 2y = 16, let x = 0 to find the y-intercept:  2y = 16, or y = 8.  The y-intercept is (0,8).  Next, let y = 0 in 4x + 2y = 16 and solve for x; this leads to the x-intercept.  4x = 16, so x = 4.  The x-intercept is then (4, 0).  Plot (4,0) and (0, 8) and draw a straight line through these two points.

Another involves solving 4x+2y=16 for y, obtaining the equivalent in slope-intercept form of this equation.  Subtracting 4x from both sides, we get 2y = 16 - 4x.  Dividing all terms by 2 results in y = -2x + 8.

As before, the y-intercept is (0,8).  Plot this point.  Now use the slope, m = -2, to find another point on this line:  Starting at (0,8), move 1 unit to the right (increasing x by 1) and then move 2 units down, arriving at (1, 6).  Plot this point.  Now draw a straight line through (1,6) and (0,8).  Your result should look the same as the previous graph you drew.

Answer:

9 bags of trail mix

Step-by-step explanation:

I would take the fraction 3/4 and make it have a common denominator with 1/12. In order to do that, multiply each number in 3/4 by 3. It results in 9/12.

You can put 9 of 1/12 in 9/12

To find out the number of bags Maya can fill with 3/4 pound of trail mix, divide 3/4 by 1/12. The division equates to multiplication by the reciprocal, so (3/4) x (12/1) = 9. Therefore, Maya can fill 9 bags of trail mix.

This problem can be solved by division. Maya has 3/4 pound of trail mix and each small bag holds 1/12 pound of trail mix. Therefore, divide 3/4 by 1/12 to find out exactly how many bags Maya can fill.

To perform this division, you could first convert the fractions to decimals or do it directly. But let's stick with fractions and apply the principle of multiplying by the reciprocal. Change the division to multiplication and multiply 3/4 by the reciprocal of 1/12.

(3/4) x (12/1) = 9

So, Maya can fill 9 bags of trail mix.

Step-by-step explanation:

I know thats the answer but I have no idea how you solve to get it. Im looking for help too.

Answer:

B. 2

Step-by-step explanation:

The multiplicity of a root is the number of times it occurs as a root.

We must solve the equation to find the number of times 3 occurs as a root.

Since we know that 3 is a root, we can use synthetic division to find the other roots.

f(x) = 2x³ -11x² + 12x + 9

3|2   -11     12     9

 |       6    -15    -9

  2   -5      -3      0

So, (2x³ - 11x² + 12x +9)/(x - 3) = 2x² - 5x – 3

=====

Let’s use synthetic division again to see if 3 is a root of this quadratic

3|2    -5    -3

 |       6      3

 2      1      0

So, 2x² - 5x – 3 = (x - 3)(2x + 1), and

2x³ - 11x² + 12x +9 = (x - 3)(x - 3)²(2x+1)

The factor x – 3 appears twice, so the root 3 has a multiplicity of two.

The sign is 4 ft on a side

The poster is 2 ft on a side

================================================

Explanation:

s = side length of the sign

p = side length of the poster

The poster "has sides measuring 2 ft less than the sides of the square sign", so p = s-2. Whatever the value of 's' is, we subtract off 2 to get the value of p. For example, if the sign has side lengths of s = 10 ft, then p = s-2 = 10-2 = 8 ft is the side length of the poster

We don't know s or p right now, so they are simply placeholders for some numbers.

If s is the side length of the sign, then s*s = s^2 is the area

If p is the side length of the poster, then p*p = p^2 is the area of the poster. We can replace p with s-2 since p = s-2. So we end up with p^2 = (s-2)^2 = s^2 - 4s + 4 after using the FOIL rule

Now subtract the two areas and set that difference equal to 12. Solve for s

(area of sign) - (area of poster) = 12

(s^2) - (s^2 - 4s + 4) = 12

s^2 - s^2 + 4s - 4 = 12

4s - 4 = 12

4s - 4+4 = 12+4

4s = 16

4s/4 = 16/4

s = 4

The sign's side length is 4, so its area is 4^2 = 16

If s = 4, then p is

p = s-2

p = 4-2

p = 2

The poster's side length is 2, so its area is 2^2 = 4

Subtract the areas: 16 - 4 = 12

The answer is confirmed

Answer:

D

Step-by-step explanation:

The quadratic formula is

[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex].

It is important because while some quadratics are factorable and can be solved not all are. The formula will solve all quadratic equations and can also give both real and imaginary solutions.  Using the formula will require less work than finding the factors if factorable. We will substitute a=5, b=4 and c=-1.

[tex]x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}\\x=\frac{-4+/-\sqrt{(4)^2-4(5)(-1)} }{2(5)}\\x=\frac{-4+/-\sqrt{16+20} }{10}[/tex]

We will now simplify and solve.

[tex]x=\frac{-4+/-\sqrt{36}}{10}\\x=\frac{-4+/-6}{10}[/tex]

x=-1 and x=0.2

35kg - a mass of sugar syrup

30% of 35kg it's a mass of sugar

30% = 30 : 100 = 0.3

30% of 35kg = 0.3 · 35kg = 10.5kg - a mass of sugar

Add xkg water. Then we have (35 + x)kg of sugar syrup and still 10.5kg of sugar.

10.5kg is 25% of (35 + x)kg .

(35 + x) -- 100%

10.5  -- 25%     multiply both sides by 4

42   -- 100%

Therefore we have the equation:

35 + x = 42      subtract 35 from both sides

x = 7

The given angle is measured clockwise with respect to {+x} axis. So, it has negative measure.

An angle is formed when two rays have the same end point. The common end point is called vertex.

Given is to identify the positive angle.

Any angle measured clockwise with respect to + x axis is negative. Similarly, any angle measured anti - clockwise with respect to + x axis is negative.

Since only one angle is shown in the image, we will describe about it. It can be seen that the angle is measured clockwise with respect to + x axis. Hence, it is negative.

Therefore, the given angle is measured clockwise with respect to {+x} axis. So, it has negative measure.

Estimate is 150 and actual product is 138.

Step-by-step explanation:

To estimate products, we round the numbers to nearest unit place, 10th, 100th, 1000th, and so on.

Given are the numbers 3 and 46.

We can round 46 ≈ 50.

So Estimation would be 3 x 46 ≈ 3 x 50

3 times 5 is 15 and we can add zeros after it.  

So estimation is 3 x 46 ≈ 150.

Now actual product would be...

3 times 6 is 18, so we note down 8 and 1 goes to carry over 4.

3 times 4 is 12 and carry 1 will be added in it, so 12 + 1 = 13.

It means the actual product is 3 x 48 = 138.

The question about the height of a tree on a scale drawing did not provide enough information for a certain answer. However, given a hypothetical height for the drawn tree, the actual height can be determined by multiplying this by the scale factor.

The subject of this question is mathematics, specifically dealing with ratios and proportions related to scale drawings. Given that the scale of the drawing is 1 in: 5 ft, this means that 1 inch on the drawing corresponds to 5 feet in real life. However, the specific height of the tree on the drawing in inches is not provided in the question, making it impossible to give a definite answer.

As an example to further explain, if the tree is drawn as 2 inches on the scale drawing, you would simply multiply by 5 (since the scale is 1 in: 5 ft) to find the actual height of the tree. So, for a 2 inch drawn tree, the actual tree would be 2 in * 5 ft/in = 10 ft tall.

But given the current information, a definite height cannot be provided. Please provide the height of the tree in inches on the scale drawing.

Formula for compounded monthly

[tex]Amount = P(1+\frac{r}{365})^{365n}[/tex]

Where P is the principle , r is the rate of interest in the decimal form and n is the number of years.

As given

Meg deposited a $3,000 bonus check in a new savings account. The account has an interest rate of 3% for 5 years.

Principle = $3000

3% is written in the decimal form

[tex]= \frac{3}{100}[/tex]

Time = 5 years

Put in the formula

[tex]Amount = 3000(1+\frac{0.03}{365})^{365\times 5}[/tex]

[tex]Amount = 3000(1+\frac{0.03}{365})^{1825}[/tex]

Answer:

The height of aquarium is [tex]\frac{3}{5}[/tex] of its length

Step-by-step explanation:

It is given that the length of rectangular aquarium is 5 decimeter

width of aquarium = [tex]\frac{4}{5}[/tex] of length

                              = [tex]\frac{4}{5} (5) = 4[/tex] decimeter

so we have

width of aquarium = 4 decimeter

Let us assume the height of aquarium be x decimeter

so the volume of the aquarium = length × width × height

Volume of aquarium = 5(4)(x)= 20x decimeter³

it is given that 40 liters of water is [tex]\frac{2}{3}[/tex] of volume of aquarium

also

1 liter = 1 decimeter³

Therefore, 40 liters = 40 decimeter³

now we have

[tex]\frac{2}{3}[/tex] of volume of aquarium = 40

[tex]\frac{2}{3}(20x)=40[/tex]

[tex]\frac{40x}{3} =40[/tex]

multiply both side by 3

[tex]40x= 3(40)[/tex]

[tex]40x=120[/tex]

divide both side by 40

[tex]x=\frac{120}{40}[/tex]

x = 3 decimeter

height of aquarium = 3 decimeter

comparing height and length

[tex]\frac{height }{length} =\frac{3}{5}[/tex]

[tex]height = \frac{3}{5} length[/tex]

hence the height of aquarium is [tex]\frac{3}{5}[/tex] of its length
