Explain.
The answer is yes, it is possible to have the sum of square roots equal the square root of the sum of the radicands.
What are square roots?A square root of a number is a value that, when multiplied by itself, gives the number.
Given that, is it possible √a+√b = √a+b
Yes, it is possible to have the sum of square roots equal the square root of the sum of the radicands.
If either a or b equals zero, then the sums would be the same.
Since the square root of 0 is ±0, adding it to a given radical would not change the radical. Also, adding zero to the radicand would not change its value.
Hence, it is possible to have the sum of square roots equal the square root of the sum of the radicands.

Write an equation of the line that passes through (4, 8) and is perpendicular to the line y = x-5.
An equation of the perpendicular line is
The slope of a line that is perpendicular to the line y = x - 5 is the negative reciprocal of the slope of y = x - 5. The slope of y = x - 5 is 1, so the slope of the line that passes through (4, 8) and is perpendicular to y = x - 5 is -1.
We can use the point-slope form of a line to write the equation of the line that passes through (4, 8) and has a slope of -1. The point-slope form of a line is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. In this case, (x1, y1) is (4, 8) and m is -1, so the equation of the line is y - 8 = -1(x - 4). Simplifying this equation, we get y - 8 = -x + 4. Adding 8 to both sides of the equation, we get y = -x + 12. This is the equation of the line that passes through (4, 8) and is perpendicular to y = x - 5.

If Hugo has 4 times as many quarters as nickels and they have a combined value of 840 cents, how many of each coin does he have?
Let Q be the number of quarters and N be the number of nickels that Hugo has. We are given that Hugo has 4 * N quarters and that the total number of quarters and nickels is worth 840 cents. Since each quarter is worth 25 cents and each nickel is worth 5 cents, the total number of quarters is worth 25 * Q cents and the total number of nickels is worth 5 * N cents. Therefore, the total number of quarters and nickels is worth 25 * Q + 5 * N cents. Since the total number of quarters and nickels is worth 840 cents, we can set up the following equation to represent this information:
25 * Q + 5 * N = 840
We are also given that Hugo has 4 * N quarters, so we can set up the following equation to represent this information:
Q = 4 * N
We can solve this system of equations to find the number of quarters and nickels that Hugo has. Substituting the value of Q in the second equation into the first equation, we get the following:
25 * (4 * N) + 5 * N = 840
Distributing the 25 on the left side of the equation, we get the following:
100 * N + 5 * N = 840
Combining like terms, we get the following:
105 * N = 840
Dividing both sides of the equation by 105, we get the following:
N = 8
Substituting the value of N into the second equation, we get the following:
Q = 4 * 8
Solving for Q, we get the following:
Q = 32
Therefore, Hugo has 8 nickels and 32 quarters.
Answer:
32 quarters
8 nickels
Step-by-step explanation:
Information:
1 quarter = 25 cents1 nickel = 5 centsDefine the variables:
Let x be the number of quarters.Let y be the number of nickels.If Hugo has 4 times as many quarters as nickels:
[tex]\implies x=4y[/tex]
If the combined value of quarters and nickels is 840 cents:
[tex]\implies 25x+5y=840[/tex]
Substitute the first equation into the second equation and solve for y:
[tex]\implies 25(4y)+5y=840[/tex]
[tex]\implies100y+5y=840[/tex]
[tex]\implies 105y=840[/tex]
[tex]\implies y=8[/tex]
Substitute the found value of y into the first equation and solve for x:
[tex]\implies x=4(8)[/tex]
[tex]\implies x=32[/tex]
Therefore, Hugo has:

Write the standard form equation for a hyperbola with center at the origin, vertices at (1, 0) and (-1, 0), and
foci at (5, 0) and (-5, 0).
Answer:
The answer is the standard form equation for a hyperbola with center at the origin, vertices at (1, 0) and (-1, 0), and foci at (5, 0) and (-5, 0), which is:
x^2 - \frac{y^2}{5} = 1
This equation describes the shape of the hyperbola and allows you to determine the location and size of the hyperbola on a coordinate plane.
Step-by-step explanation:
The standard form equation for a hyperbola with center at the origin, vertices at (1, 0) and (-1, 0), and foci at (5, 0) and (-5, 0) is given by:
$$\frac{x^2}{a^2} - \frac{y^2}{b^2} = 1$$
where $a$ and $b$ are the lengths of the semi-major and semi-minor axes, respectively. In this case, the distance between the vertices is 2, so the semi-major axis is 1 and the semi-minor axis is $\sqrt{5}$. Therefore, the equation of the hyperbola is:
$$\frac{x^2}{1^2} - \frac{y^2}{\sqrt{5}^2} = 1$$
which simplifies to:
x^2 - \frac{y^2}{5} = 1
What are the types of triangles based on their sides and angles? How do you classify a triangle as equilateral, isosceles, scalene, acute, right, or obtuse? Give an example of each.
Based on their sides, the 3 triangles are classified as equilateral triangles, isosceles triangles, and scalene triangles.
A triangle is scalene if all of its three sides and angles are differentScalene-Triangle-1
In the figure, all three symbols that are given on each side are different, which denotes that all three sides are unequal.
If two of its sides are equal, a triangle is called an isosceles.One example of the angles of an isosceles acute triangle is 50°, 50°, and 80°.
A triangle with all three equal sides is called equilateral.The sum of all three angles of an equilateral triangle is equal to 180 degrees. 60° + 60° + 60° = 180°
Acute angles measure less than 90 degrees.the examples of acute angles are 25°, 36°, 47°, 64°, 55°, 72°, 80° and so on
Right angles measure 90 degrees.Examples of right angles are all around us. We can see right angles in the corners of a room, book, cube, windows, and at several other places.
Obtuse angles measure more than 90 degreesExamples of obtuse angles include 166°, 121°, 110°, 117°, and 91°.

if x,10,2x-4, and 12 are in proportion find the value of x
Answer:
x=5
Step-by-step explanation:
To find the value of x, we need to first set up the proportion using the given information. Since the given values are in proportion, we can set up the proportion as follows:
x / 10 = (2x - 4) / 12
Next, we can cross-multiply to solve for the value of x:
12x = 10(2x - 4)
12x = 20x - 40
-8x = -40
x = 5
Thus, the value of x is 5. This means that the other values in the proportion are also 5, 10, 10, and 12, respectively.
Points A, B, and C are collinear. What is the slope of AB in simplest form?
The slope of the line AB in simplest form is 3/2.
What is slope?The slope is the rate of change of the y-axis with respect to the x-axis.
The equation of a line in slope-intercept form is y = mx + b, where
slope = m and y-intercept = b.
We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.
We also know that the slope is rise over run, rise represents the y-axis and run represents the x-axis.
From B to C rise is 3 and from B to C run is 2.
Therefore, the slope of the line AB is 3/2.

for a normal distribution, assume the 'population' standard deviation is 7.7. what is the maximal margin of error associated with a 90% confidence interval for the true population mean if n
for a normal distribution, assume the 'population' standard deviation is 7.7. .645 * 7.7 / √(n) is the maximal margin of error associated with a 90% confidence interval for the true population mean if n
The margin of error is calculated as
Margin of Error = Critical Value * Standard Deviation / √(Sample Size)
= 1.645 * 7.7 / √(n)
= 1.645 * 7.7 / √(n)
The margin of error is a measure of the accuracy of an estimate based on a sample from a population. It is calculated by taking the critical value (1.645, for a 90% confidence interval) multiplied by the population standard deviation (7.7), divided by the square root of the sample size (n). The higher the sample size, the smaller the margin of error. This means that a larger sample size gives a more accurate estimate of the true population mean.

Which equation has infinitely many solutions? 5(2x 4) = 10x – 12 5(2x 4) = 10(x 2) 5(2x 4) = 12x 5(2x 10) = 20(x 1)
The equation that has infinitely many solutions is 5(2x + 4) = 10(x + 2).
An equation can have infinitely many solutions when both sides of the equation satisfy the same conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line. For the given equations it can determine if the equation has infinitely many solutions by simplifying the equation and see if both sides are equal. Hence,
5(2x + 4) = 10x – 12
10x + 20 ≠ 10x - 12
5(2x + 4) = 10(x + 2)
10x + 20 = 10x + 20
5(2x + 4) = 12x
10x + 20 ≠ 12x
5(2x + 10) = 20(x + 1)
10x + 50 ≠ 20x + 20
Hence, 5(2x + 4) = 10(x + 2) has infinitely many solutions.
