What is perimeter?The distance around the boundary of a two-dimensional shape. It is the sum of all the sides of the shape is termed as perimeter.
We know that ΔABC is similar to ΔDEF. Therefore, the corresponding sides of both triangles are proportional.
First, we can find the length of the base DF of ΔDEF using the fact that the triangles are similar:
AB/DE = AC/DF = BC/EF
8/6 = 15/DF = 17/EF
DF = (15/8)× 6 = 11.25m (rounded to two decimal places)
EF = (17/8) × 6 = 12.75m (rounded to two decimal places)
The scale factor of ΔABC to ΔDEF can be found by comparing the height AB to the height DE:
Scale factor = AB/DE = 8/6 = 4/3
Perimeter of ΔDEF = Scale factor * Perimeter of ΔABC = (4/3) × (8 + 15 + 17) = 40
Area of ΔDEF = (Scale factor)² × Area of ΔABC = (4/3)² × (1/2 × 8 × 15) = 80/3 = 26.67 square meters (rounded to two decimal places)

Consider the line 5x+2y=−4. What is the equation of the line parallel to the given line that passes through the point (−2, 6) in slope-intercept form? Enter your answer by filling in the boxes to complete the equation.
Answer:
y = -5/2x +1
Step-by-step explanation:
You want the slope-intercept form equation for the line through the point (-2, 6) that is parallel to 5x +2y = -4.
Parallel lineThe equation of a parallel line can be the same as the given equation, except for the constant. The new constant can be found by substituting the given point coordinates:
5(-2) +2(6) = c
-10 +12 = c
2 = c
Now we know the equation of the parallel line can be written as ...
5x +2y = 2
Slope-intercept formSolving for y puts this in slope-intercept form:
2y = -5x +2 . . . . . . . . subtract 5x
y = -5/2x +1 . . . . . . . . divide by 2
We don't know what your boxes look like, but we can separate the numbers to make it look like this:

1. Anya is at camp and walks 2km due north and then turns and walks another 3km at a bearing angle of 35° . Find her distance back to camp and the bearing angle from her starting point.
Anya her distance back to camp and the bearing angle from her starting point is 4.78 km North 26.3° West.
Define direction ?
Direction gives the information about the way towards which an object moves or tends.
The angle formed by the 2 km and 3 km is the supplement of the 35 ° angle west of north;
180°- 35° = 145°
We know that the length of two sides and one angle.
The opposite side know angle is the direct distance between the starting and ending points.
Using the law of cosines.
\(a^{2} = b^{2} + c^{2} - 2bc (cosA)\)
\(a^{2} = 2^{2} + 3^{2} - 2(2)(3)(cos 145)\)
\(a^{2} = 4 + 9 - 12 (-0.8192)\)
\(a^{2} = 22.83\)
a = 4.78 km
To determine the bearing from the starting point , we must determine the angle between the first leg and the direct path.
Using the law of sines
\(\frac{4.78}{sin(145)} = \frac{3}{sin C}\) sin(145°)
4.78 sin C = 3 sin 145°
sin C = \(\frac{3 sin (145^ 0)}{4.78}\)
sin C = 0.4438
C = 26.3°
Therefore, the distance and bearing of the end point from the starting point is 4.78 km North 26.3 ° West.

What requirements are necessary for a normal probability distribution to be a standard normal probability distribution?
Answer:
The requirements that are necessary for a normal probability distribution to be a standard normal probability distribution are µ = 0 and σ = 1.
Step-by-step explanation:
A normal-distribution is an accurate symmetric-distribution of experimental data-values.
If we create a histogram on data-values that are normally distributed, the figure of columns form a symmetrical bell shape.
If X \(\sim\) N (µ, σ²), then \(Z=\frac{X-\mu}{\sigma}\), is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z \(\sim\) N (0, 1).
The distribution of these z-variates is known as the standard normal distribution.
Thus, the requirements that are necessary for a normal probability distribution to be a standard normal probability distribution are µ = 0 and σ = 1.

Julia can swim 8 km/hr in still water. She attempts to head straight east across a river flowing south at 3 km/hr. What is the magnitude and direction of Julia's velocity.
To solve this problem, we need to use vector addition to find the resultant velocity of Julia.
Let's assume that the east direction is the positive x-axis and the south direction is the negative y-axis.
The velocity of Julia in still water is 8 km/hr in the positive x-axis direction.
The velocity of the river is 3 km/hr in the negative y-axis direction.
To find the magnitude and direction of Julia's velocity, we need to find the resultant velocity vector, which is the vector sum of her velocity in still water and the velocity of the river.
Using the Pythagorean theorem, the magnitude of the resultant velocity can be calculated as:
|V| = √(Vx² + Vy²)
where Vx is the x-component of the resultant velocity and is equal to Julia's velocity in still water, and Vy is the y-component of the resultant velocity and is equal to the velocity of the river.
Vx = 8 km/hr
Vy = -3 km/hr
|V| = √(8² + (-3)²) = √(64 + 9) = √73 km/hr
The direction of the resultant velocity can be calculated as:
θ = tan⁻¹(Vy / Vx)
θ = tan⁻¹(-3 / 8) = -20.56°
The negative sign indicates that the resultant velocity vector makes an angle of 20.56° below the positive x-axis (east direction).
Therefore, the magnitude of Julia's velocity is approximately 8.54 km/hr, and the direction of her velocity is 20.56° below the positive x-axis (east direction).
Find the equation of the straight line passing through the point (-4,5) and perpendicular to the line y=2x+7.Suppose the equation is y=cx+d.Find c,d.
Answer:
The equation of the line is:
\(y = -\frac{1}{2}x + 3\)
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
\(y = mx + b\)
In which m is the slope and b is the y-intercept.
Perpendicular lines:
If two lines are perpendicular, this means that the multiplication of their slopes is -1.
Perpendicular to y=2x+7
This means that:
\(2m = -1\)
\(m = -\frac{1}{2}\)
So
\(y = -\frac{1}{2}x + b\)
Passing through the point (-4,5)
This means that when \(x = -4, y = 5\). We use this to find b.
\(y = -\frac{1}{2}x + b\)
\(5 = -\frac{1}{2}(-4) + b\)
\(2 + b = 5\)
\(b = 3\)
The equation of the line is:
\(y = -\frac{1}{2}x + 3\)

what is the minimum and maximum value in the range?
Answer:
domain (x), we include values [-4, 3]
range (y), we include values [-3, 4]
Step-by-step explanation:
The domain is the possible x-values of a function, the range is the possible y-values of a function.
On this graph, only x-values -4 to 3 have y-values / have a value on this graph.
And on this graph, only y-values -3 to 4 have values graphed/have an x-value.
When writing range and domain, we write (minimum, maximum)

**We use ( ) when not including a value
and [ ] when including a value.
(For example, if a line extends to infinity, that must be put in parentheses because you can never reach /include infinity)

enter your response here%. (Round to two decimal places.)

Given that money market account investment at 2.55 percent (APY), a 1.11 % inflation rate, a 28 percent marginal tax bracket, and a constant $60000 balance.
Cash management is the backbone of any business. Cash management ensures that the company operates according to established standards and optimizes the use of funds to avoid wasting resources. Liquidity management decisions are therefore key to preserving a company's capital and profitability.
Firstly, we will find the after-tax return rate, we get
After-tax return rate= Before tax rate of return \times ( 1 - tax rate)
After-tax rate of return = 0.0255× ( 1 - 0.28)
After-tax rate of return = 0.0255×0.72
After-tax rate of return=1.84%
Now, we will find the real return, we get
Real return=((1+After-tax Return)/(1+inflation rate))-1
Real return=((1+0.0184)/(1+0.0111))-1
Real return=(1.0184/1.0111)-1
Real return=1.00721-1
Real return=0.721%
Furthermore, we will find the total monetary return, we get
Total monetary rate=Balance×Before tax rate of return
Total monetary rate=60000×2.55%
Total monetary rate=$1530.
The implications of this result for cash management decisions is that it becomes very challenging to grow with such a return as the taxes and inflation is draining the returns and leaving only with negative returns.
Hence, the after-tax rate of return is 1.84%, the real return is 0.721%, the total monetary return is $1530 and the implications become very challenging to grow with such a return as the taxes and inflation is draining the returns and leaving only with negative returns.

Answer:
there are 45 pages in the book
Step-by-step explanation:
If Joe has read 40% of the book, then he has 60% of the book left to read. Let's let "x" represent the total number of pages in the book.
If Joe has 18 pages left to read, that means he has already read:
0.6x = x - 18
Solving for x, we get:
0.4x = 18
x = 45
Therefore, there are 45 pages in the book.

The equation gives the position s = f(t) of a body moving
on a coordinate line (s in meters, t in seconds).
1) s = 1 + 9(cos t)
Find the body's speed at time t=pi/3 sec.
2) s = 12(sin t) - (cos t)
Find the body's velocity at time t=pi/4 sec.
Answer:
1) The velocity at this time is of \(-9\frac{\sqrt{3}}{2}\) meters per second.
2) The velocity at this time is of \(13\frac{\sqrt{2}}{2}\) meters per second.
Step-by-step explanation:
This question involves concepts of derivatives.
The velocity is the derivative of the position.
We use these following derivatives:
\((\sin{x})^{\prime} = \cos{x}\)
\((\cos{x})^{\prime} = -\sin{x}\)
1) s = 1 + 9(cos t)
Find the body's speed at time t=pi/3 sec.
We have to find the derivative at \(t = \frac{\pi}{3}\). So
\(v = (1 + 9\cos{t})^{\prime} = -9\sin{t}\)
\(v(\frac{\pi}{3}) = -9\sin{\frac{\pi}{3}}\)
\(\frac{\pi}{3}\) is a common angle, which has a sine of \(\frac{\sqrt{3}}{2}\). So
\(-9\sin{\frac{\pi}{3}} = -9\frac{\sqrt{3}}{2}\)
The velocity at this time is of \(-9\frac{\sqrt{3}}{2}\) meters per second.
2) s = 12(sin t) - (cos t)
Find the body's velocity at time t=pi/4 sec.
We have to find the derivative at \(t = \frac{\pi}{4}\). So
\(v = (12\sin{t} - \cos{t})^{\prime} = 12\cos{t} + \sin{t}\)
\(\frac{\pi}{4}\) is a common angle, which has both sine and cosine of \(\frac{\sqrt{2}}{2}\). So
\(12\cos{\frac{\pi}{4}} + \sin{\frac{\pi}{4}} = 12\frac{\sqrt{2}}{2} + \frac{\sqrt{2}}{2} = 13\frac{\sqrt{2}}{2}\)
The velocity at this time is of \(13\frac{\sqrt{2}}{2}\) meters per second.

The solutions to the system of equations are x = 2 and 4
How to determine the solution to the system of equationsFrom the question, we have the following parameters that can be used in our computation:
f(x) = x - 3
g(x) = 1/(x - 3)
The solution to the system of equations implies that
f(x) = g(x)
So, we have
x - 3 = 1/(x - 3)
Cross multiply the equation
This gives
(x - 3)² = 1
So, we have
x - 3 = ±1
Add 3 to both sides
x = 3 ± 1

4 cm
6 cm
8 cm
12 cm
The opposite sides PQ and RS of the parallelogram PQRS are congruent
The value of the length QS is 6 cm
How to determine the length QS?The given parameters are:
PQ = 4x - 1
RS = 3x + 7
Opposite sides are congruent.
So, we have:
4x - 1 = 3x + 7
Collect like terms
4x - 3x = 1 + 7
Evaluate the expressions
x = 8
The perimeter is calculated using:
Perimeter = 2(QS + RS)
This gives
2(QS + RS) = 74
Divide by 2
QS + RS = 37
Substiute RS = 3x + 7
QS + 3x + 7 = 37
Substitute 8 for x
QS + 3*8 + 7 = 37
This gives
QS + 31 = 37
Subtract 31 from both sides
QS = 6
