Answer:
1
Step-by-step explanation:
The square root of 1 is called 1.
In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4. The square root of 9 is 3, because 3 x 3 = 9.
The square root of 1 is 1, because 1 x 1 = 1. Therefore, the square root of 1 is simply called 1.

What's the inverse of f x )= 1 4x 7?
The inverse of f is a function which takes any value x and divides it by 4, then adds 7 to the result.
The inverse of a function is the opposite of the original function, meaning that it takes the output of the original function and turns it back into the input. In this case, the original function is f(x)=1/4x+7. To find the inverse, we need to solve for x in the equation, which can be done by subtracting 7 from both sides and then multiplying both sides by 4. This gives us x=(x+7)/4, which is the inverse of the original function. To put it simply, the inverse of f takes any output of the original function, adds 7 to it, and then divides it by 4 to get the original input.
example;
If f(x)=1/4x+7 and x=3, then
f(3) = (1/4)3 + 7
7.75
The inverse of f is f^-1(x) = (x + 7) / 4.
If f^-1(7.75) = (7.75 + 7) / 4, then
f^-1(7.75) = 14.75 / 4

What additional information do you need to know in order to prove the two triangles congruent using HL?
There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.
1. SSS (side, side, side)-If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
2. SAS (side, angle, side) -If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
3. ASA (angle, side, angle)-If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
4. AAS (angle, angle, side)-If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
5. HL (hypotenuse, leg)
This one applies only to right angle triangles
From the figure,
HL stands for "Hypotenuse, Leg" (the longest side of a right-angled triangle is called the "hypotenuse", the other two sides are called "legs")
It means we have two right-angled triangles with
The same length of hypotenuse andThe same length for one of the other two legs.It doesn't matter which leg since the triangles could be rotated.
For example: From fig(2)
is congruent to fig(3)
If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.

A farmer grows only sunflowers and flax on his 240-acre farm.
This year he wants to plant 80 more acres of sunflowers than of flax. How many
acres of each crop does the farmer need to plant?
Answer:
Flax: 80 acres
Sunflowers: 160 acres
Step-by-step explanation:
Let's
x = acres of flax
y = acres of sunflowers
We have the equations:
x + y = 240
y = x + 80
Let's do it in standard form
x + y = 240
x - y = -80
2x = 160
x = 80 acres
Now put 80 back in the equation to find sunflowers
80 + y = 240
y = 160 acres
So, 80 acres of flax and 160 acres of sunflowers!

Why does SSS similarity work?
The two triangles are similar if all three sides of one triangle are in proportion to the three sides of another triangle.
SSS, which stands for "side, side, side," denotes that we have two triangles with the same number of sides on each pair of corresponding sides. Two triangles are comparable if they have three pairs of sides that are in the same ratio. According to the SSS test for triangle similarity, two triangles are considered similar if their third sides are proportionate to one another.
In our daily lives, the idea of comparable triangles is really useful. By measuring the shadows' lengths and then utilizing triangles that are comparable to them, we can determine an object's height, such as the height of a building or a tower. Compare the shortest sides first, followed by the longest sides, when applying the SSS Similarity Theorem. Two triangles are similar if their corresponding side lengths are proportionate to one another.

The breadth of a box is two third of its length and height is one third of its length. if the volume of box is 48m³, find the area of the base of the box.
Answer:
Step-by-step explanation:
To find the area of the base of the box, we need to determine the length, breadth, and height of the box. We can set up a system of equations to represent the given information:
breadth = 2/3 * length
height = 1/3 * length
volume = length * breadth * height
Substituting the second equation into the third equation, we get:
volume = length * breadth * (1/3 * length)
= length^2 * (2/3) * (1/3)
= (2/9) * length^2
= 48
= 2^4 * 3
Solving for length, we find that length = 6. Plugging this value back into the first equation, we find that breadth = 4.
Therefore, the area of the base of the box is length * breadth = 6 * 4 = 24 square meters.
Discuss the difference between r and p. Does r represent population correlation coefficient
Or critical value for the correlation coefficientorsample correlation coefficient.
r stands for the Pearson correlation coefficient, which measures the strength and direction of the linear relationship between two variables. p stands for the critical value for the correlation coefficient, which is used to determine the significance of the correlation coefficient.
The Pearson correlation coefficient (r) is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship. The correlation coefficient is a good way to determine the strength of the relationship between two variables.The critical value for the correlation coefficient (p) is used to determine the significance of the correlation. It is determined by the sample size, the number of variables being correlated, and the level of significance. The lower the P value, the more significant the correlation is. If the P value is below the chosen level of significance, then the correlation is considered statistically significant.In conclusion, r is the Pearson correlation coefficient and p is the critical value for the correlation coefficient. R measures the strength and direction of the linear relationship between two variables, while P indicates the significance of the correlation. Both measures are important when assessing the relationship between two variables.

What is the vertex of 2x² 8x 3?
The vertex of the graph of f(x) = 2x² + 8x - 3 is (-2, -11). It lies in the third quadrant.
Therefore the answer is (-2, -11).
Simplifying the given graph to the form f(x) = a(x - h)² + k
f(x) = 2x² + 8x - 3
f(x) = 2×(x² + 4x) - 3
f(x) = 2×(x² + 4x + 4) - 3 - 2×4
f(x) = 2×(x + 2)² - 11
So f(x) = 2x² + 8x - 3 is symmetrical about the line x = -2. At x = -2, y = -11.
Therefore, the vertex of the graph is (-2, -11).

What is the sum of interior angles of a convex polygon?
If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = (n −2) × 180°
According to the given question:
Number of sides in the given polygon n = 5
Therefore, sum of interior angles of the polygon S = (n -2 ) x 180°
S = (5 -2) x 180°
S = 3 x 180°
S = 540°
Now to find the value of c we can simply add all the interior angles given in the figure and equate it to S
Hence,
136° + 119° + 147° + 48° + 45c = 540°
450° + 45c = 540°
45c = 90°

f(x) = −(x − 5)2 − 4
f(x) = (x + 5)2 − 4
f(x) = (x − 5)2 − 4
The vertex form of our quadratic equation is:
y = (x - 5)^2 - 4
What is the vertex form of the quadratic?A quadratic equation with a vertex (h, k) and a leading coefficient a is:
y = a*(x - h)^2 + k
We know that the quadratic function has roots of 3 and 7, then if the leading coefficient is a, we can write:
f(x) = a*(x - 3)*(x - 7)
We also know that it passes through the point (1, 12), then:
12 = a*(1 - 3)*(1 - 7)
12 = a*(-2)*(-6)
12 = a*12
12/12 = a
1 = a
Then the quadratic is:
y = (x - 3)*(x - 7)
Expanding that we get:
y = x^2 - 3x - 7x + 21
y = x^2 - 10x + 21
The x-value of the vertex is halfway between the two roots:
x' = (3 + 7)/2 = 5
So evaluating in x = 5 we get:
y = (5)2 - 10*5 + 21
y = 25 - 50 + 21 = -4
The vertex is (5, -4), then the vertex form is:
y = (x - 5)^2 - 4
