800 × 740 = 592000

592000 in scientific notation looks like this 5.92 × 10^5

Hope this helps!!

Answer:

5.92 x 10^5

Step-by-step explanation:

The product of the two is 592000 and to do scientific notation you put the decimal after the first number and however many numbers are after that decimal is the number 10 is to the power of.  To know if the exponent after the ten is positive or negative if you move the decimal to the right in order to make it the original number it is positive, and if you have to move it to the left  then you have a negative exponent after the 10.

The question is incomplete. The full question is below.

The path of a particular punt follows the quadratic function

[tex]h(x)=\frac{-1}{8}(x-25)^{2}+50[/tex]

where h(x) is the height of the ball in yards and x corresponds to the horizontal distance in yards. Assume x=0 corresponds to midfield (the 50 yards line). For example, x=20 corresponds to the punter's own 30 yard line, whereas corresponds to the other team's 30 yard line.

a. Find the maximum height the ball achieves.

b. Find the horizontal distance the ball covers. Assume the height is zero when the ball is kicked and when the ball is caught.

Answer: a. Maximum height = 50

              b. Horizontal distance = 40

Step-by-step explanation: A quadratic function has its maximum or minimum point on its vertex.

When the function is negative, function has a maximum point.

The quadratic function h(x) is written in vertex form, meaning the coordinate of vertex is explicit in the function.

General vertex form: [tex]f(x)=A(x-h)^{2}+k[/tex]

A is vertical scaling parameter

(h,k) are the coordinates of vertex

So, the quadratic function for the height for the ball:

[tex]h(x)=\frac{-1}{8}(x-25)^{2}+50[/tex]

shows its vertex:

(h,k) = (25,50)

a. The maximum height the ball achieves the maximum value corresponds to the y-axis, which means, maximum height is 50 yards.

b. Horizontal distance is when h(x)=0, so:

[tex]\frac{-1}{8}(x-25)^{2}+50=0[/tex]

[tex]\frac{-1}{8}(x-25)^{2}=-50[/tex]

[tex](x-25)^{2}=400[/tex]

[tex]x^{2}-50x+625=400[/tex]

[tex]x^{2}-50x+225=0[/tex]

Solving quadratic equation:

[tex]x_{1}=\frac{50+\sqrt{1600} }{2}[/tex] = 45

[tex]x_{2}=\frac{50-\sqrt{1600} }{2}[/tex] = 5

When ball is kicked, it is in position 5. When is caught, is position 45. So, distance the balls covers is 40 yards.

Answer:

Step-by-step explanation:

If MP bisects ∠BMS, then the line MP divides <BMS equally;

The adition postulate if therefore true;

<BMP +< PMS = <BMS and <BMP = < PMS

The equation becomes;

<BMP +< BMP= <BMS

2 <BMP = <BMS

2(2x+9) = 7x - 3

4x+18 = 7x-3

collect like terms

4x-7x = -3-18

-3x = -21

x = 21/3

x = 7

Since <BMP = < PMS 2x+9

< PMS = 2(7)+9

< PMS = 14+9

< PMS = 23

Hence the value of < PMS is 23

The relative frequencies add to 100% for each row.

Step-by-step explanation:

y = mx + c

y intercept= (0,-4) , x intercept = (3,0)

m = (y2-y1)/(x2-x1)

m = (0-(-4))/(3-0)

m = 4/3

0 = (4/3)(3)+ c

c = -4

Answer:

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side. Note: This rule must be satisfied for all 3 conditions of the sides.

Answer:

This is easy just like the other one you posted before

b+53+245=360

b+298=360

b=360-298

b=62

Answer:

62

Step-by-step explanation:

360 degrees is the total … You get the point.

360 degrees - 245 degrees

= 115 degrees

Now, we go onto the angle

The total measure of the angle is 115 degrees

The angle has been split into two angles. On of the angles measure is 53 degrees. To find the measure of the other angle, you have to subtract the measure of the angle that was given 53 degrees) by the total measure (115 degrees):

115 degrees - 53 degrees

= 62 degrees

Hope this helped you!

  27.  1

Step-by-step explanation:

When you're asked to find f(n), locate n on the x-axis, then move up or down along the grid line until you meet the curve. Then move horizontally to the f(x) axis and read the value from that.

This process is illustrated in the attachment.

__

To find f(x) = n, reverse the process. Locate n on the f(x) axis, then move horizontally to the curve, then vertically to the x-axis. That is the value of x you're looking for.

For this graph, and many unmarked graphs, it is often reasonable to assume each grid square is 1 unit in either direction. (The graph title or axis labels may tell you differently.)

Answer: Required 99% confidence interval  : (48.30%, 61.7%)

Step-by-step explanation:

Confidence interval for PROPORTION:  [tex]p\pm z^* \times S.E.[/tex], where p = sample proportion , z* = two-tailed critical z-value  and S.E. = standard error.

As per given: p=55%

Critical z-value for 99% confidence = 2.576

S.E. = 2.6%

Then, required confidence interval :

[tex]55\% \pm (2.576)\times 2.6\%\\\\\approx55\% \pm6.70\%\\\\=(55\%-6.70\%,\ 55\%+6.70\%)\\\\=(48.30\%,\ 61.7\%)[/tex]

Required 99% confidence interval  : (48.30%, 61.7%)

Answer:

9.9%

Step-by-step explanation:

Well, you would just divide the "other" category and the "total" category and then move the decimal over 2 spaces, because you need to multiply by 100 to turn your answer into a percent, so:

Then once you multiply by 100, or move the decimal to the left 2 spaces, it becomes:

9.9%, which could be rounded to 10% or 9%.

Answer:

Area= 54 cm^2

Step-by-step explanation:

Recall that a rhombus is given by the product of its two diagonals (d1 and d2) divided by 2.

Area = d1 * d2 / 2

So in our case, the longer diagonal is 12 cm long, and the shortest one should be in the ratio 3:4, therefore:

3 /4 = d2 / d1

3 / 4 = d2 / 12

d2 = 3 * 12 /4

d2 = 3 * 3

d2 = 9 cm

Then we can now calculate the Area of the rhombus as;

Area = d1 * d2 / 2 = 12 * 9 / 2 = 54 cm^2

Answer:

(a) The probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.

(b) Thus, the probability of municipal bonds issued by suburbs is 0.325.

Step-by-step explanation:

The data provided is as follows:

P (A) = 0.70

P (B) = 0.20

P (C) = 0.10

P (c | A) = 0.50

P (s | A) = 0.40

P (r | A) = 0.10

P (c | B) = 0.60

P (s | B) = 0.20

P (r | B) = 0.20

P (c | C) = 0.90

P (s | C) = 0.05

P (r | C) = 0.05

(a)

The Bayes' theorem states that the conditional probability of an event Y[tex]_{i}[/tex] given that another event X has already occurred is:

[tex]P(Y|X)=\frac{P(X|Y)P(Y)}{\sum\limits_{i} {P(X|Y_{i})P(Y_{i})}}[/tex]

Compute the probability that the new municipal bond issued will receive an A rating given that it was issued by a city as follows:

[tex]P(A|c)=\frac{P(c|A)P(A)}{P(c|A)P(A)+P(c|B)P(B)+P(c|C)P(C)}[/tex]

           [tex]=\frac{(0.50\times 0.70)}{(0.50\times 0.70)+(0.60\times 0.20)+(0.10\times 0.90)}\\\\=\frac{0.35}{0.56}\\\\=0.196[/tex]

Thus, the probability that the new municipal bond issued will receive an A rating given that it was issued by a city is 0.196.

(b)

The law of total probability states that:

[tex]P(X)=\sum\limits_{i} {P(X|Y_{i})}[/tex]

Compute the probability of municipal bonds issued by suburbs as follows:

[tex]P(s)=P(s|A)P(A)+P(s|B)P(B)+P(s|C)P(C)[/tex]

        [tex]=(0.40\times 0.70)+(0.20\times 0.20)+(0.10\times 0.05)\\\\=0.28+0.04+0.005\\\\=0.325[/tex]

Thus, the probability of municipal bonds issued by suburbs is 0.325.

Answer:

The concentration of pollutants in the water can be defined as the quotient between the mass of pollutants and the total mass of water.

Assuming that 1L of water weighs 1000 grams, we know that:

Mass of pollutants = 5mg = 0.005g.

Initial concentration = 0.005g/1000g = 0.000005

If we multiply this by 100%, we get the percentage:

0.000005*100% = 0.0005%

Now, the mass of pollutants decreases by 10% each hour.

So if initially, we have 5mg

After one hour, we will have: 5mg - 0.1*5mg = 5mg*(0.9).

After another hour, we will have: 5mg*(0.9) - 0.1*5mg*0.9 = 5mg*(0.9)^2.

And so on, then after n hours, the mass of pollutants will be:

M(n) = 5mg*(0.9)^n

Or we can write this in grams as:

M(n) = 0.005g*(0.9)^n

Then the concentration as a function of time in hours will be:

C(n) = M(n)/1000g = (0.005g/1000g)*(0.9)^n

Notice that the thing between the parentheses is the initial concentration, then if we write this in percentage form:

c(n) = 100%*(0.005g/1000g)*(0.9)^n = 0.0005%*(0.9)

The function that represents the concentration of polution in the water as a function of hours is:

c(n) = 0.0005%*(0.9)
