with (x₁, y₁ ) = A (5, 1 ) and (x₂, y₂ ) = B (- 3, - 3 )
AB = [tex]\sqrt{(-3-5)^2+(-3-1)^2}[/tex]

12. In PQR if mP is 14 less than five times x, mQ is five less than x, and mR is nine less
than twice x, find x and the measure of each angle.
Answers
Answer:
Step-by-step explanation:
mP=5x-14
mQ=x-5
mR=2x-9
we know that all the angles in a triangle= 180
that means (5x-14)+(x-5)+(2x-9)=180
5x-14+x-5+2x-9=180 we add the variables and the numbers
8x=180+28
8x=108
x=26
mP=130-14=116
mQ=26-5=21
mR=43

Which quadratic function is represented by the table? f(x) = 3x2 2x – 5 f(x) = 3x2 – 2x 5 f(x) = 2x2 3x – 5 f(x) = 2x2 – 2x 5
Answers
For the values of x, the quadratic function f(x) = 3x² – 2x + 5 is satisfied. Then the correct option is B.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
At x = –2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–2)² – 2(–2) + 5
f(x) = 12 + 4 + 5
f(x) = 21
At x = –1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(–1)² – 2(–1) + 5
f(x) = 3 + 2 + 5
f(x) = 10
At x = 0, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(0)² – 2(0) + 5
f(x) = 0 + 0 + 5
f(x) = 5
At x = 1, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(1)² – 2(1) + 5
f(x) = 3 – 2 + 5
f(x) = 6
At x = 2, the f(x) will be
f(x) = 3x² – 2x + 5
f(x) = 3(2)² – 2(2) + 5
f(x) = 12 – 4 + 5
f(x) = 13

Find the length of the third side. If necessary, round to the nearest tenth 22 25
Answers
Solution :
We'll solve this using the Pythagorean Theorem.Let,
Let BC be perpendicular.22 be AB, where AB is the Base.25 be AC, where AC is the Hypotenuse.We know that,
[tex]{ \longrightarrow \bf \qquad \: (AB) {}^{2} +( BC) {}^{2} = (AC) {}^{2} }[/tex]
[tex]{ \longrightarrow \sf \qquad \: (22) {}^{2} +( BC) {}^{2} = (25) {}^{2} } [/tex]
[tex]{ \longrightarrow \sf \qquad \: (BC) {}^{2} = (25) {}^{2} - ( 22) {}^{2} }[/tex]

[tex]{ \longrightarrow \sf \qquad \: BC = \sqrt{141} }[/tex]
[tex]{ \longrightarrow \bf \qquad \: BC \approx11.87 }[/tex]
Therefore,
The length of the third side is 11.9 (Nearest tenth of 11.87) .Step-by-step explanation:
According to Pythagoras theorem ,
Hypotenuse² = Perpendicular ² + Base ²
Here , we have to find perpendicular
Hypotenuse = 25 unitBase = 22 unitSo,
Hypotenuse² - Base² = Perpendicular²
putting the known values
25² - 22² = perpendicular²
141 = perpendicular²
√141 = perpendicular
Perpendicular = 11.9 unit

Step-by-step explanation:
Step by step explanation is on the pic above
Answer:
y = 6x
Step-by-step explanation:
We can find the relationship by looking at each value for X and Y and finding which number makes the equation true
The first equations says Y = 3 when X = 0.5, Lets put this into an equation
[tex]3= ?*0.5[/tex]
The only number that would make this equation true is 6
[tex]3=0.5*6[/tex]
Lets try another, The Third equation says that Y = 9 when X = 1.5
[tex]9 = 1.5*?[/tex]
Again, the only number that works is 6
[tex]9=1.5*6[/tex]
Hence the equation for this table is [tex]Y=6x[/tex]

Step-by-step explanation:
A. True, because represents a quadratic function (the greatest power of x is 2)
B. False, because this function is quadratic, so cannot be linear
C. False. The vertex of the parabola is at point (-7,4) (see diagram)
D. True. The axes of symmetry is the line x=-7 that passes through the vertex.
E. False. The y-intercept is at point x=0 and
F. True. The graph has the maximum at the vertex, where
G. False. The graph of the parabola intersects the x-axis at two points (-9,0) and (-5,0), so x=-9 and x=-5 are two real solutions of the equation f(x)=0.
A right triangle has legs of length 136 cm and 119 cm. What is the length of the hypotenuse of the right triangle? Enter the answer, rounded to the nearest tenth, in the box.
Answers
Answer:
Hypotenuse= 180.7 cm
Step-by-step explanation:
Using Pythagoras' theorem:
a^2+b^2=c^2 (let c= Hypotenuse "H")
(136)^2 + (119)^2 = H^2
18496+14161 =H^2
H^2= 32657
Taking square root on both sides
[tex]\sqrt{H}[/tex]= [tex]\sqrt{32657}[/tex]

What is the approximate volume of the earth? How much larger is Earth than Mars?
Answers
Answer:
Step-by-step explanation:
The volume of a sphere is defined to be:
[tex]V=\frac{4}{3} \pi r^3[/tex]
Plug in the values for both planets. The radii of the planets was already given:
[tex]V_e=\frac{4}{3} \pi (6378.1)^3[/tex]
[tex]V_e=1.1*10^1^2kg^3[/tex]
[tex]V_m=\frac{4}{3} \pi (3390.0)^3[/tex]
[tex]V_m=1.6*10^1^1kg^3[/tex]
Earth is this many times larger than Mars:
[tex]\frac{V_e}{V_m} =\frac{1.1*10^1^2}{1.6*10^1^1} =6.9[/tex]
