Step-by-step explanation:
since we are taking about true halves (I hope), both halves "weigh" the same, and a percentage in one has the same absolute value as in the other.
then the answer is just based on the mean value between both percentages :
x = percentage of the second half
70 = (78 + x)/2
140 = 78 + x
x = 140 - 78 = 62%
she needs at least 62% on the second half to pass the 70% minimum limit of the whole test.
Since the equations for both triangles have a2 + b2, you can think of the two equations for c2 and n2 as a system of equations. Substitute what a2 + b2 equals in the first equation for a2 + b2 in the second equation. After you substitute, what equation do you get?
The second equation results in n^2 = c^2.
Let's suppose we have two equations:
Equation 1: c^2 = a^2 + b^2
Equation 2: n^2 = a^2 + b^2
Both equations have the term a^2 + b^2. We can treat these equations as a system of equations and substitute the value of a^2 + b^2 from Equation 1 into Equation 2.
Substituting a^2 + b^2 from Equation 1 into Equation 2, we get:
n^2 = c^2
After substituting, we obtain the equation n^2 = c^2. This equation shows that the squares of the lengths of the sides n and c are equal.
It's important to note that this result holds true because both triangles have the same a and b values, leading to the same value of a^2 + b^2. Therefore, substituting that value into the second equation results in n^2 = c^2.

If Anita and Miguel do not take any money from their accounts, whose account will grow faster? Explain why.
Savings accounts and CDs are good options for people who want to save money without taking on a lot of risk.
If Anita and Miguel do not take any money from their accounts, Anita's account will grow faster than Miguel's.
This is because the interest rate for Anita's account is 6%, while Miguel's is 5%.

f(x) = x^2−4x+2, find the value(s) for x such that f(x)=23.
Step-by-step explanation:
To find the value(s) for x such that f(x) = 23, we can set up the equation:
x^2 - 4x + 2 = 23
To solve this quadratic equation, we need to rearrange it into the standard quadratic form:
x^2 - 4x - 21 = 0
Now, we can solve this equation by factoring, completing the square, or using the quadratic formula. In this case, let's use the quadratic formula:
x = (-b ± √(b^2 - 4ac)) / (2a)
For the equation x^2 - 4x - 21 = 0, the coefficients are: a = 1, b = -4, and c = -21.
Plugging these values into the quadratic formula, we get:
x = (-(-4) ± √((-4)^2 - 4(1)(-21))) / (2(1))
x = (4 ± √(16 + 84)) / 2
x = (4 ± √100) / 2
x = (4 ± 10) / 2
Now, we have two solutions:
x = (4 + 10) / 2 = 14 / 2 = 7
x = (4 - 10) / 2 = -6 / 2 = -3
Therefore, the values for x such that f(x) = 23 are x = 7 and x = -3.

En un terreno rectangular que mide 64 cm por 18 cm, van a construir en el 50 % una casa ¿Cuál es el área construida?
The built area of 50% of the house on the rectangular piece of land measures 576 cm^2.
To find the built area of 50% of a house on a rectangular piece of land, we need to calculate the area of the rectangular piece of land and then determine 50% of that area.
The rectangular piece of land has dimensions of 64 cm by 18 cm. To calculate the area, we multiply the length by the width:
Area = Length * Width
Area = 64 cm * 18 cm
Area = 1152 cm^2
The total area of the rectangular piece of land is 1152 cm^2.
To find the built area, which is 50% of the total area, we multiply the total area by 50% (or 0.5):
Built Area = Total Area * 50%
Built Area = 1152 cm^2 * 0.5
Built Area = 576 cm^2
Therefore, the built area of 50% of the house on the rectangular piece of land measures 576 cm^2.
It's important to note that this calculation assumes that the built area is uniformly distributed on the land and represents half of the house's total area. The actual shape and distribution of the house may vary, but this calculation provides an estimate of the built area based on the given information.

I
The equation of the line parallel to a line joining points (1,-2) and (-4,3) and passing through (-4,-5) is
(Simplify your answer. Type your answer in slope-intercept form.)
The equation of the line parallel to the line passing through (1, -2) and (-4, 3) and passing through the point (-4, -5) is y = -x - 9 in slope-intercept form.
To find the equation of a line parallel to a given line, we need to determine the slope of the given line and then use it to construct the equation of the parallel line.
First, let's calculate the slope of the given line passing through points (1, -2) and (-4, 3). The slope, denoted as m, can be found using the slope formula:
m = (y2 - y1) / (x2 - x1)
Substituting the coordinates, we have:
m = (3 - (-2)) / (-4 - 1) = 5 / (-5) = -1
Now that we have the slope, we can use it to construct the equation of the parallel line.
We'll use the point-slope form of a linear equation, which is:
y - y1 = m(x - x1)
where (x1, y1) represents the coordinates of a point on the line.
We'll use the point (-4, -5) on the parallel line:
y - (-5) = -1(x - (-4))
y + 5 = -1(x + 4)
Simplifying further:
y + 5 = -x - 4
y = -x - 9

What are the endpoints of a line segment?The endpoints themselves are distinct points on a line, and they are included as part of the line segment. Unlike a line, which extends indefinitely in both directions, a line segment is confined to a specific length.
This length is often referred to as the 'measure' of the line segment. Additionally, line segments serve as building blocks for various geometrical shapes and figures by connecting multiple points in space.

Which of the following gives the correct range for the piecewise graph?
A coordinate plane with a segment going from the point negative 3 comma 2 to 0 comma 1 and another segment going from the point 0 comma 1 to 5 comma negative 4.
The correct range for the piecewise graph is [-4, 2].
To solve this problemWe need to find the minimum and maximum values of the y-coordinates.
The first segment goes from (-3, 2) to (0, 1), so the range for this segment is from 1 to 2.
The second segment goes from (0, 1) to (5, -4), so the range for this segment is from -4 to 1.
We must take into account the minimum and maximum values from each segments in order to determine the overall range. The minimum and highest values are -4 and 2, respectively.

Two cyclists, 54 miles apart, start riding toward each other at the same time. One cycles 2 times as fast as the other. If they meet 2 hours later, what is the speed (in mi/h) of the faster cyclist?
Answer:
In summary, the faster cyclist cycles at a speed of 18 mi/h since they travel 36 of the 54 miles in 2 hours while cycling twice as fast as the slower cyclist.
Explanationn:
The two cyclists are 54 miles apart and heading toward each other.
One cyclist cycles 2 times as fast as the other. We will call the faster cyclist A and the slower cyclist B.
They meet 2 hours after starting. This means they travel a total distance of 54 miles in 2 hours.
Since cyclist, A cycles 2 times as fast as cyclist B, cyclist A travels 2/3 of the total distance, and cyclist B travels 1/3 of the total distance.
In two hours, cyclist A travels (2/3) * 54 miles = 36 miles.
We need to find the speed of cyclist A in miles per hour.
Speed = Distance / Time
So the speed of cyclist A is:
36 miles / 2 hours = 18 miles per hour
Therefore, the speed of the faster cyclist is 18 mi/h.

If sinθ = 5/13 and θ is in Quadrant II, then sin (θ/2) will be equal to [tex]\frac{5}{\sqrt{26}}[/tex]
How to Solve Half-AnglesTo find sin(θ/2), we can use the half-angle identity for sine, which states that:
sin(θ/2) = ±[tex]\sqrt{\frac{(1 - cos\theta)}{2}}[/tex]
Given that sinθ = 5/13 and θ is in Quadrant II, we can determine the value of cosθ using the Pythagorean identity
sin²θ + cos²θ = 1
sinθ = 5/13
sin²θ = (5/13)² = 25/169
cos²θ = 1 - sin²θ = 1 - 25/169 = 144/169
cosθ = ±√(144/169) = ±12/13
Since θ is in Quadrant II, the cosine is negative. Therefore, cosθ = -12/13.
Now, we can calculate sin(θ/2):
sin(θ/2) = ±√((1 - cosθ) / 2) = ±√((1 - (-12/13)) / 2) = ±√((1 + 12/13) / 2) = ±√(25/26) = ±5/√26
Since θ is in Quadrant II, sin(θ/2) will be positive.
Therefore, sin(θ/2) = 5/√26.

The value v of a tractor purchased for $13,000 and depreciated linearly at the rate of $1,300 per year is given by v= -1,300t+13,000, where t represents the number of years since the
purchase. Find the value of the tractor after (a) two years and (b) six years. When will the tractor have no value?
a) the value of the tractor after two years is $10,400.
b) the value of the tractor after six years is $5,200.
To find the value of the tractor after a certain number of years, we can substitute the value of t into the equation v = -1,300t + 13,000.
a) After two years:
Substituting t = 2 into the equation, we get:
v = -1,300(2) + 13,000
v = -2,600 + 13,000
v = 10,400
Therefore, the value of the tractor after two years is $10,400.
b) After six years:
Substituting t = 6 into the equation, we get:
v = -1,300(6) + 13,000
v = -7,800 + 13,000
v = 5,200
Therefore, the value of the tractor after six years is $5,200.
To find when the tractor will have no value, we need to find the value of t when v = 0. We can set the equation v = -1,300t + 13,000 equal to 0 and solve for t:
-1,300t + 13,000 = 0
-1,300t = -13,000
t = -13,000 / -1,300
t = 10

The true airspeed T (in knots) of an airplane can be modeled by T=(1+A50,000) ⋅ S, where A is the altitude (in feet) and S is the indicated airspeed (in knots).
3. Write the equation for true airspeed T in terms of altitude and differential pressure p.
The equation for true airspeed T in terms of altitude and differential pressure p - T = k * (1 + A/50,000) * p
To write the equation for true airspeed T in terms of altitude A and differential pressure p, we need to consider the relationship between indicated airspeed S and differential pressure.The indicated airspeed S is typically measured using a pitot tube, which measures the dynamic pressure of the air flowing around the aircraft. The differential pressure p represents the difference between the dynamic pressure measured by the pitot tube and the static pressure of the surrounding air. In other words, p = dynamic pressure - static pressure.
The equation T = (1 + A/50,000) * S, we can express S in terms of the differential pressure p. Let's assume that S is directly proportional to p:
S = k * p
where k is a constant of proportionality. By substituting this expression for S into the equation for true airspeed, we have:
T = (1 + A/50,000) * (k * p)
Simplifying, we can write the equation for true airspeed T in terms of altitude A and differential pressure p as:
T = k * (1 + A/50,000) * p
where k is the constant of proportionality relating differential pressure to indicated airspeed.

How much money should be deposited today in an account that earns 4.5% compounded monthly so that it will accumulate to $15,000 in 4 years
Answer:
P ≈ $12,654.89
Step-by-step explanation:
To calculate the amount of money that should be deposited today, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = the future value of the investment ($15,000 in this case)
P = the principal amount (the amount to be deposited today)
r = the annual interest rate (4.5% or 0.045 as a decimal)
n = the number of times the interest is compounded per year (monthly compounding, so n = 12)
t = the number of years (4 years in this case)
Substituting the given values into the formula, we have:
$15,000 = P(1 + 0.045/12)^(12*4)
Simplifying the equation:
$15,000 = P(1.00375)^(48)
To solve for P, we divide both sides of the equation by (1.00375)^(48):
P = $15,000 / (1.00375)^(48)
Using a calculator, we find:
P ≈ $12,654.89
Therefore, approximately $12,654.89 should be deposited today in order to accumulate to $15,000 in 4 years with a 4.5% annual interest rate compounded monthly.

Find the equation of the tangent line to the following curve
at the indicated point.
The equation of the tangent line at the point (108, 6) on the curve y² = x²/(xy - 324) is: y = 6
How to find the equation of the tangent?
The equation is given as:
y² = x²/(xy - 324) at (108, 6)
Differentiating implicitly with respect to x gives:
2y(dy/dx) = (2x(xy - 324) - x²(y - 324)(dy/dx)) / (xy - 324)²
Simplifying further using power rule and chain rule gives us:
[tex]\frac{dy}{dx} = \frac{x^{2}y - 648x }{2y(-324 + xy) +x^{3} }[/tex]
We can find the slope by plugging in x = 108 and y = 6 to get
[tex]\frac{dy}{dx} = \frac{(108^{2}*6) - 648(108) }{2(6)(-324 + (108*6)) + 108^{3} }[/tex]
dy/dx = 0
To find the equation of the tangent line, we use the point-slope form:
y - y₁ = m(x - x₁),
where:
(x₁, y₁) is the given point (108, 6) and m is the slope.
Substituting the values, we have:
y - 6 = 0(x - 108)
y = 6
This is the equation of the tangent line at the point (108, 6) on the curve y² = x²/(xy - 324).

As x tends to negative one from the left, the value of f(x) tends to positive infinity. As x → -1⁻, f(x) → ∞.
What is a vertical asymptote?In Mathematics and Geometry, the vertical asymptote of a function simply refers to the value of x (x-value) which makes its denominator equal to zero (0).
By critically observing the graph of this rational function f(x) shown below, we can logically deduce that its vertical asymptote is at x = -1 and x = 2, and its horizontal asymptote is at y = 3.
In this context, we can logically deduce that the value of f(x) tends towards positive infinity, as x tends to negative one from the left;
