Answer:
36 ft
Step-by-step explanation:
The ratio of the lengths of the sides is the same as the ratio of the perimeters.
Just like one side (15 ft) of triangle ABC is 3 times as long as the corresponding side (5 ft) of triangle DEF, the perimeter of triangle ABC is also 3 times the perimeter of triangle DEF.
15/5 = x/12
3 = x/12
x = 36
Answer: 36 ft
What is the equation of the line which passes through 4 2 and has a slope of -2?
Answer:
Point slope form is the best form to use for this particular question.
We reflect point slope form as: \(y-y_{1} =m(x-x_1)\)
M reflects the slope, and the X and Y values are the coordinates given.
M = -2, X = 4, Y = 2
This should result in an equation that looks like this:
\(y-2=-2(x-4)\)
Now, if we want to turn this equation into slope-intercept form, we have to do some calculations. First of all, we have to multiply -2 with (x-4) to get
\(y-2=-2x+8\)
Next, we add two on both sides to isolate the Y variable.
Therefore, the slope-intercept equation would be: \(y=-2x+10\)
the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring.T/F
The probability of the intersection of two events occurring can never be more than the probability of the union of two events occurring.
False.
It should be stated that the likelihood of the intersection of two events occurring is always less than the likelihood of the events occurring together.
It is always less likely than or equal to the likelihood of either event occurring alone for an intersection of two events, which is the chance that both occurrences take place.
In other words, the probability of the intersection and the probability of the union are subsets of one another.
The chance of the intersection of two events occurring can never be greater than the likelihood of the union of two events occurring, hence that is the right statement.

The required answer is the series ∑ln(6k)4k diverges.
determine whether the series ∑ln(6k)4k converges or diverges.
To analyze the convergence or divergence of the given series, we can use the Ratio Test:
1. Find the ratio of consecutive terms: a_(k+1)/ask
In this case, a_k = ln(6k)4k.
2. Compute the limit as k approaches infinity: lim(k->∞) (a_(k+1)/a_k)
a_(k+1) = ln(6(k+1))4(k+1) and a_k = ln(6k)4k
3. Compute the ratio: (ln(6(k+1))4(k+1))/(ln(6k)4k)
4. Find the limit as k approaches infinity: lim(k->∞) [(ln(6(k+1))4(k+1))/(ln(6k)4k)]
5. Apply L'Hopital's rule for indeterminate forms (0/0 or ∞/∞) if needed.
If limit exist and partial sum converges or individual term approaches zero then series is convergent otherwise divergent and further checked by methods explained below.
In this case, however, we notice that the terms in the series do not go to zero, since ln(6k)4k will always grow larger as k increases. This implies that the series does not converge.
Thus, the series ∑ln(6k)4k diverges.

if you want to round a number within an arithmetic expression, which function should you use?
If you want to round a number within an arithmetic expression, you should use the ROUND function.
The ROUND function allows you to specify the number of decimal places to which you want to round a given number. It is commonly used in programming languages and spreadsheet software.
The syntax for the ROUND function typically involves specifying the number or expression you want to round and the number of decimal places to round to. For example, if you want to round a number, let's say 3.14159, to two decimal places, you would use the ROUND function like this: ROUND(3.14159, 2), which would result in 3.14.
Using the ROUND function ensures that the rounded number is calculated within the arithmetic expression, providing the desired level of precision in the calculation.

Which equation below represents the inverse function b(a), which takes the
trapezoid's area as input and returns as output the length of the other base?
O A. b(a)=+7
B. b(a)--7
O C. b(a)- +5
OD. b(a)-2-5
Note that the function takes the trapezoid's area as input and returns as output the length of the other base is A(x)/7-5=x.
What is the area of a Trapezoid?Recall that the function for the trapezoid area is:

find the standard equation of the circle which satisfies the following criteria: endpoints of a diameter: (−6, 7) and (−4, 3)
The standard equation of the circle with endpoints of a diameter (−6, 7) and (−4, 3) can be expressed as (x+5)^2+(y-5)^2 = 13.
First, calculate the midpoint of the two points given, which can be calculated by taking the average of the x-coordinates and the average of the y-coordinates. The midpoint is then (-5,5).
Then, calculate the radius of the circle by taking the distance between the midpoint and one of the given points, which in this case is the distance between (-5,5) and (-6,7). Using the distance formula, the radius of the circle is √10.
Finally, use the general equation of a circle to find the standard equation of the circle that satisfies the criteria given. The general equation of a circle is (x−h)^2+(y−k)^2=r^2, where (h,k) is the center of the circle and r is the radius of the circle. Since the center of the circle is (-5,5) and the radius is √10, the equation can be rewritten as (x+5)^2+(y-5)^2 = 13.

Step-by-step explanation:
F(X,Y)=3x2+5y2 Fx(−5,2)=
The value of Fx(-5,2) is -30. To find Fx(-5,2), we first need to take the partial derivative of F with respect to x.
F(x,y) = 3x^2 + 5y^2
Taking the partial derivative of F with respect to x, we get:
Fx(x,y) = 6x
Now, to find Fx(-5,2), we simply plug in -5 for x and 2 for y:
Fx(-5,2) = (6 * -5)
Fx(-5,2) = -30
Therefore, the value of Fx(-5,2) is -30.
In the given function F(x,y) = 3x^2 + 5y^2, the partial derivative Fx indicates how much the function changes with respect to changes in x while keeping y constant. In other words, it measures the instantaneous rate of change of the function in the x-direction at the given point (-5,2). A negative value for Fx(-5,2) indicates that the function is decreasing in the x-direction at that point.

The height at time t (in seconds) of a mass, oscillating at the end of a spring, is s(t) = 300 + 16 sin t cm. We have to find the velocity and acceleration at t = π/3 s.
Let's first find the velocity of the mass. The velocity of the mass is given by the derivative of the position of the mass with respect to time.t = π/3 s
s(t) = 300 + 16 sin t cm
Differentiating both sides of the above equation with respect to time
v(t) = s'(t) = 16 cos t cm/s
Now, let's substitute t = π/3 in the above equation,
v(π/3) = 16 cos (π/3) cm/s
v(π/3) = -8√3 cm/s
Now, let's find the acceleration of the mass. The acceleration of the mass is given by the derivative of the velocity of the mass with respect to time.t = π/3 s
v(t) = 16 cos t cm/s
Differentiating both sides of the above equation with respect to time
a(t) = v'(t) = -16 sin t cm/s²
Now, let's substitute t = π/3 in the above equation,
a(π/3) = -16 sin (π/3) cm/s²
a(π/3) = -8 cm/s²
Given, s(t) = 300 + 16 sin t cm, the height of the mass oscillating at the end of a spring. We need to find the velocity and acceleration of the mass at t = π/3 s.
Using the above concept, we can find the velocity and acceleration of the mass. Therefore, the velocity of the mass at t = π/3 s is v(π/3) = -8√3 cm/s, and the acceleration of the mass at t = π/3 s is a(π/3) = -8 cm/s².
At time t = π/3 s, the velocity of the mass is -8√3 cm/s, and the acceleration of the mass is -8 cm/s².

The sum of the series is 44.
Step-by-step explanation:
Sigma notation. I just had a test on this, so this is pretty good timing.
Below the sigma, we see that k = 1. This means that 1 is the number you would substitute for k into the expression on the right to get the first term. In this case, the first term is -2. (2(1)² - 4)
Now, we can also find out the number of terms in the series by subtracting 1 (taken from k = 1) from the number on top of the sigma, 4, and then adding 1 to it.
4 - 1 + 1 = 4. This means there are 4 terms in the series.

From which store should Dylan make his purchase if he wants to get the best price per unit?
Answer:
Store 1
Step-by-step explanation:
Given
See attachment
Required
Determine the store with the best price per unit
It should be noted that the store with the best has the least price per unit.
So, we have:
Store 1
\(Quantity = 10\ ft\)
\(Price = \$2.50\)
The unit rate is:
\(Rate = \frac{Price}{Quantity}\)
\(Rate = \frac{\$2.50}{10\ ft}\)
Rate = $0.250 per feet
Store 2
\(Quantity = 2\ yd\)
\(Price = \$1.85\)
Convert quantity to feet
\(Quantity = 2 * 3ft = 6ft\)
The unit rate is:
\(Rate = \frac{Price}{Quantity}\)
\(Rate = \frac{\$1.85}{6\ ft}\)
Rate = $0.308 per feet
Store 3
\(Quantity = 12\ ft\)
\(Price = \$3.40\)
The unit rate is:
\(Rate = \frac{Price}{Quantity}\)
\(Rate = \frac{\$3.40}{12\ ft}\)
Rate = $0.283 per feet
Store 4
\(Quantity = 5\ yd\)
\(Price = \$4.00\)
Convert quantity to feet
\(Quantity = 5 * 3ft = 15ft\)
The unit rate is:
\(Rate = \frac{Price}{Quantity}\)
\(Rate = \frac{\$4.00}{15\ ft}\)
Rate = $0.267 per feet
From the calculations above; store 1 has the least unit rate.
Hence, store 1 has the best price per unit
