Answer:
[tex]d=\sqrt{149}\approx12.21[/tex]
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
We have the two points (-1, 7) and (-8, -3).
Let (-1, 7) be (x₁, y₁) and let (-8, -3) be (x₂, y₂). Substitute:
[tex]d=\sqrt{(-8-(-1))^2+(-3-7)^2}[/tex]
Evaluate:
[tex]d=\sqrt{(-8+1)^2+(-10)^2}[/tex]
Evaluate:
[tex]d=\sqrt{(-7)^2+(-10)^2}[/tex]
Square:
[tex]d=\sqrt{49+100}[/tex]
Add:
[tex]d=\sqrt{149}\approx12.21[/tex]
This cannot be simplified. Hence, the distance between (-1, 7) and (-8, -3) is √(149) or approximately 12.21 units.

what is the equation in point slope form of a line that passes through the points (-4,-1)and5,7)
Answer:
[tex]\frac{8}{9}[/tex]
Step-by-step explanation:
using the image attached as reference
(-4,-1) - the -4 becomes x1, and the -1 becomes y1
(5,7) - the 5 becomes x 2 and the 7 becomes y2
plug this information into the equation
7-(-1)
m=----------
5-(-4)
solve
8
m=----------
9
so your slope would become 8/9
prove a stronger version of proposition 2.3.7 suppose xn ia a sequence such that every subsequence xni has a subsequence xnmi that converges to x
Answer and Step-by-step explanation:
Solution:
Given:
A, B and C are sets.
We have to prove that:
(A − B) ∩ (C − B) = (A ∩ C) − B.
Use an element x,
Let x Є (A – B), by the definition of difference:
X Є A and x ∉ B.
And
X Є A ∩ C and x ∉ B
X Є (A ∩ C) – B
Now let x Є C – B
By the definition of difference:
X Є C and x ∉ B
By definition of intersection: x Є C and x Є( A ∩ C)
By definition of difference, using that x Є(A ∩ C) And x ∉ B:
X Є ( A ∩ C) – B
We know that: x Є (A – B) ∩ ( C – B)
Is equivalent to x Є A – B and x Є C – B
So, ( x Є A and x ∉ B)
And (x Є C and x ∉ B)
From this we know that x Є (A ∩ C) – B.
The classic 60° triangle has a hypotenuse of length 2, an opposite side of length √3 and an adjacent side of length 1....find the value of Cos(60°)
Answer:
The trigonometric values for cos are C = A/H, which means that to find cos(60), you need to divide the adjacent side by the hypotenuse, which in this case gives you 1/2, so that is the value of cos(60).

71 2/3 as a fraction
Answer:
215/3
Step-by-step explanation:
71 multiplied by 3 (denominator) + 2 (remainder) divided by 3
The improper fraction for the given mixed fraction is 215/2.
The given fraction is [tex]71\frac{2}{3}[/tex].
These are just improper fractions written as a sum of whole number and a proper fraction. (improper fraction has the upper value(also called numerator) bigger or equal to denominator(the bottom value) and proper fraction has numerator value is less than that of the denominator)
They are written and can be converted to fraction as: [tex]a\frac{b}{c} = \frac{(a\times c)+b}{c}[/tex]
Now, [tex]71\frac{2}{3}=\frac{71\times3+2}{3}[/tex]
= (213+2)/3
= 215/3
Therefore, the improper fraction for the given mixed fraction is 215/2.

Nora is 4 years older than Hina . If the sum of their ages is at most 45 years ,find the maximum possible age of Hina. *
b) 25 years
a) 20 years
c) 15 years
choose the correct answer
Answer:
a) 20 years
Step-by-step explanation:
Hina: x
Nora: x + 4
x + x + 4 ≤ 45
2x + 4 ≤ 45
2x ≤ 41
x ≤ 20.5
20 years old and 15 years old would be ≤ 20.5 but the question asked for maximum possible age so 20 years old it is.

67.699 which rounded to the nearest tenth is:
67.7
Answer:
67.7Step-by-step explanation:
perimeter = semicircle (x2) + parallelogram side (x2)
= 1/2 π 12 (x2) + 15 (x2)
= 37.7 + 30
= 67.7

General Formulas and Concepts:
Algebra I
Standard Form: ax² + bx + c = 0Expanding by FOIL (First Inside Outside Last)Combining like termsStep-by-step explanation:
Step 1: Define equation
y = -(x - 3)² + 8
Step 2: Rewrite
Expand [FOIL]: y = -(x² - 6x + 9) + 8Distribute -1: y = -x² + 6x - 9 + 8Combine like terms: y = -x² + 6x - 1Which of the following is a factor of 7x2 - 12x - 4? (6 points)
O 7x - 2
O x + 2
Ox-4
O None of the above
Answer:
We conclude that 'None of the above' is the correct answer.
Step-by-step explanation:
Given the expression
[tex]7x^2\:-\:12x\:-\:4[/tex]
Breaking the expression into groups
[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]
Factor out [tex]x[/tex] from [tex]7x^2\:+\:2x[/tex]
[tex]=x\left(7x+2\right)[/tex]
Factor out -2 from [tex]\left(-14x-4\right)[/tex]
[tex]=-2\left(7x+2\right)[/tex]
so the expression becomes
[tex]7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)[/tex]
[tex]=x\left(7x+2\right)-2\left(7x+2\right)[/tex]
Factor out the common term [tex]7x+2[/tex]
[tex]=\left(7x+2\right)\left(x-2\right)[/tex]
Therefore, from the given options, we conclude that 'None of the above' is the correct answer.

What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
We have to given that;
Fraction = 4/5
So, Write an equivalent fraction as;
⇒ 4/5
Multiply by 2 in denominator and numerator;
⇒ 4×2 / 5×2
⇒ 8 / 10
⇒ 0.8
