Answer:

Step-by-step explanation:

AC = length of flagpole = 12 ft

AB = length of shadow = 14 ft

BC = length from the top of the flagpole to the end of the shadow = x ft

Use Pythagorean theorem to find the length of x,

x² = AC² + BC²

   = 12² + 14²

  = 144 + 196

  = 340

x = √340

x = 18.4 ft

The time is required for a 5.75 mg sample of 51cr to decay to 0.700 mg is 99.4 days

What is decay constant?

Decay constant k = ln(2) / half life

= ln(2) / 27.8

= 0.024933 day⁻¹

For first order decay:

ln(M / M₀)  = -kt

where M is mass remaining at time t and  M₀ is initial mass.

ln(0.700/5/75) = -0.024933 * t

Time, t = 99.4 days

Hence, time is required for a 5.75 mg sample of 51cr to decay to 0.700 mg is 99.4 days.

Answer:

it goes down by 4 every time

Answer:

(a) 40% of the animals are cows.

(b) 60% of the animals are pigs.

Step-by-step explanation:

(a) You have to find the percent of the cows. 2:3 can be written as 2/5 for the cows and you have to figure out x/100.

2/5 = x/100

5*20 = 100

2*20 = x

40 = x

(b) The rest of the animals on the farm are pigs so you have to subtract 40 from 100 for the answer.

100-40 = y

60 = y

Answer:

The perfect factored square trinomial that is equivalent to the expression x^2 + 8x + 16 is:

(x + 4)^2

To see why this is the case, you can expand the expression (x + 4)^2 using the FOIL method:

(x + 4)^2 = (x + 4) * (x + 4)

= x^2 + 4x + 4x + 16

= x^2 + 8x + 16

So, x^2 + 8x + 16 can be factored as (x + 4)^2, which is a perfect square trinomial.

Answer:

sin(X)=cos(Z)

Step-by-step explanation:

trig ratio sin(x) = O/H

(where O = side opposite the angle and H = hypotenuse)

Therefore, if angle = X, O = 27 and H = 45

 \(\implies sin(X)=\dfrac{27}{45}\\\\\implies sin(X)=\dfrac35\)

trig ratio cos(x) = A/H

(where A = side adjacent to the angle and H = hypotenuse)

So if A = 27 and H = 45 then

\(cos(Z)=\dfrac{27}{45}\\\\\implies cos(Z)=\dfrac{3}{5}\)

Therefore, \(sin(X)=cos(Z)\)

The effect on f(x) is that it is shifted one unit to the left on the x-axis to obtain g(x).

Here,

In mathematics, a graph is a visual representation of a set of objects, called vertices or nodes, and the connections between them, called edges or links.

The function f(x) is translated to g(x) by subtracting 1 from the exponent of 3.

This means that g(x) is obtained by shifting f(x) one unit to the right on the x-axis.

The coefficient of 2 remains unchanged, which means that the overall scaling of the function remains the same.

Therefore, the effect on f(x) is that it is shifted one unit to the left on the x-axis to obtain g(x).

In other words, the graph of g(x) is obtained by taking the graph of f(x) and shifting it to the right by one unit.

There are 7 green marbles in a bag and 9 yellow marble. Randomly selecting three marbles, the probability that all three marbles are green is 0.082 or approximately 8.2%

Assuming that the marbles are drawn without replacement (meaning that after the marble is drawn, it is not placed again into the bag), the possibility of drawing three inexperienced marbles is:

a) First marble: 7/16 (on account that there are 7 green marbles out of 16 total)

Second marble: 6/15 (due to the fact there are actually 6 green marbles out of 15 closing)

Third marble: 5/14 (on account that there at the moment are 5 inexperienced marbles out of 14 final)

Multiplying these possibilities collectively offers:

(7/16) x (6/15) x (5/14) = 0.036

Therefore, the opportunity of drawing 3 green marbles is 0.036, or approximately three.6%.

Note that the probability would be distinct if the marbles were drawn with an alternative (that means that every marble is positioned back into the bag before the next marble is drawn). In that case, the opportunity of drawing an inexperienced marble on each draw would be 7/16, and the opportunity of drawing 3 green marbles in a row might be (7/16) x (7/16) x (7/16)   = 0.082 or approximately 8.2%

Therefore , the probability that she selects none of those containing errors is 0.6798.

Calculating how likely or "possible" it is for an event to occur is the subject of probability. Words like "definitely," "impossible," or "likely" may be used to communicate the likelihood that a particular event will occur. Mathematics always expresses probabilities as fractions, decimals, or percentages, with values ranging from 0 to 1.

Here,

Number of ways of selecting 3 returns out of 59 is C(59,3).

Out of 59 returns, 59-7 = 52 returns has no error so number of ways of selecting 3 returns out fo 52 is C(52,3).

The probability that she selects none of those containing errors is

P( No errors )=\(\frac{C(52,3)}{C(59,3)}\)=0.6798

Therefore , the probability that she selects none of those containing errors is 0.6798.

The dimensions of the container is r = 6.828 cm and h = 13.656 cm.

Volume of the Cone:

Volume of the cone is define the space or the capacity of the cone.

The formula for the volume of the cone is,

V = πr²h

Where

r represents the radius of the cone

h represents the height of the cone

Given,

Cylindrical container must hold 2l or 2,000 cm³ of liquid.

Here we need to find the dimensions of the container which will minimize the amount of material needed.

Let height = h and radius of the base = r.

We know that the volume of the container,

V = 2000

We know the formula of volume of the cone is,

V = πr²h

2000 = πr²h

Here we need the value of h,

So,

h = 2000/πr²

and surface area of the can

S = 2πr² + 2πrh

Apply the value of h,

S = 2πr² + 2πr (2000/πr²)

S = 2πr²+ (4000/r)

S = 2πr²+ 4000 x r⁻¹

S′=(−1)(4000r⁻²)+4πr

S′=4πr−(4000/r²)

Consider,

4πr−(4000/r²) = 0

4πr³−4000 = 0

πr³−1000 = 0

πr³ = 1000

r³ = 1000 / π

r = √1000 / π

r =  6.828 cm

Apply the value of r on the equation to find the value of h,

h = 2000/(π∗(6.828)²)

h = 2000/146.46

h = 13.656

The correct answer is "half the width of the confidence interval."

The margin of error of a confidence interval about the difference between the means of two populations is equal to half the width of the confidence interval.

In a confidence interval, the width represents the range between the upper and lower bounds of the interval. The margin of error indicates the maximum amount by which the sample estimate can deviate from the true population parameter.

To calculate the margin of error, you divide the width of the confidence interval by 2. This is because the margin of error represents the distance from the sample estimate to the upper or lower bound of the interval. By dividing the width by 2, we determine the maximum amount of deviation from the estimate allowed on either side.

Therefore, the correct answer is "half the width of the confidence interval."

The fraction that Brian can iron in a minute is 5/81.

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. It should be noted that in a simple fraction, the numerator as well as the denominator are both integers. On the other hand, a fraction appears in the numerator or the denominator of a complex fraction.

Here, set up a proportion (shirt ironed/minutes = shirt ironed/minutes). I'll convert 3 3/5 to an improper fraction as well to set it up.

(2/9) / (18/5) = x / 1

Cross multiply

2/9 = (18/5)x

Multiply both sides by 5/81 to solve for x.

x = 10/162

In this case, it should be noted that we can reduce 10/162 to the lowest term. This will be 5/81
