Answer:

M+N, M.N, M.S, N+T are irrational numbers.

Step-by-step explanation:

Given

M=\sqrt2,\\ N=\sqrt5, \\S=2, \\T=5

we have to select irrational number from

M+N, M.N, S+T, S.T, M.S, N+T, N^2

M+N=\sqrt2+\sqrt5 \thinspace(irrational)\\\\M.N=(\sqrt2)(\sqrt5)=\sqrt{10}\thinspace(irrational)\\\\S+T=2+5=7\thinspace (rational)\\\\S.T=2.(5)=10\thinspace(rational)\\\\M.S=(\sqrt2)2=2\sqrt2\thinspace(irrational)\\\\N+T=\sqrt5+5\thinspace (irrational)\\\\N^2=(\sqrt5)^2=5\thinspace(rational)

Hence, M+N, M.N, M.S, N+T are irrational numbers.

10. Write an inequality relating the measure of angle 1 to the measure of angle 2
patriot [66]
The two triangles are isosceles.

Both triangles have the equals sides equal to 6

Both ∠ 1 and the ∠2 are the opposite angles to the different side of their respective triangles.

The opposite side to ∠ 1 is shorter than the opposite side to ∠ 2, which implies that ∠1 is less than ∠2.

Then the inequality that relates those angles is

 ∠1 < ∠2

84. Use properties of exponents to rewrite each expression with only positive, rational exponents. Then find the numerical value
Yakvenalex [24]

Answer:

a) 1/27

b) 16

c) 1/8

Step-by-step explanation:

a) x^{-3/2}

One of the properties of the exponents tells us that when we have a negative exponent we can express it in terms of its positive exponent by turning it into the denominator (and changing its sign), so we would have:

x^{-3/2}=\frac{1}{x^{3/2} }

And now, solving for x = 9 we have:

\frac{1}{x^{3/2}}=\frac{1}{9^{3/2} }  =\frac{1}{27}

b) y^{4/3}

This is already a positive rational exponent so we are just going to substitute the value of y = 8 into the expression

y^{4/3}=8^{4/3}=16

c) z^{-3/4}

Using the same property we used in a) we have:

z^{-3/4}=\frac{1}{z^{3/4} }

And now, solving for z = 16 we have:

\frac{1}{z^3/4} } =\frac{1}{16^{3/4} } =\frac{1}{8}

The graph below shows the height of a kicked soccer ball f(x), in feet, depending on the distance from the kicker x, in feet: Gr
siniylev [52]
Because the vertex of the parabola is at (16,0), its equation is of the formy = a(x-10)² + 15
The graph goes through (0,0), thereforea(0 - 10)² + 15 = 0100a = -15a = -0.15
The equation is y = f(x) = -0.15(x - 10)² + 15
The graph is shown below.
Part A
Note that y = f(x).
The x-intercepts identify values where the function or  y=0. The x-intercepts occur at x=0 and x=20, or at (0,0) and (20,0).
The maximum value of y occurs at the vertex (10, 15) because the curve is down due to the negative leading coefficient of -0.15.
The curve increases in the interval x = (-∞, 10) and it decreases in the interval x = (10, ∞).
Part B
When x=12, y = -0.15(12 - 10)² + 15 = 14.4When x=15, y = -0.15(15 - 10)² + 15 = 11.25
The average rate of change between x =12 to x = 15 is(11.25 - 14.4)/(15 - 12) = -1.05
This rate of change represents the slope of the secant line from A to B. It approximates the rate at which f(x) decreases in the interval x =[12, 15].
