Compute: 100 to the power of 999 times 5 to the power of negative 999 times 2 to the power of negative 999.
100 = 10² = 2² × 5², so
100⁹⁹⁹ = (2² × 5²)⁹⁹⁹
100⁹⁹⁹ = 2²ˣ⁹⁹⁹ × 5²ˣ⁹⁹⁹
100⁹⁹⁹ = 2¹⁹⁹⁸ × 5¹⁹⁹⁸
Then
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 2¹⁹⁹⁸ × 5¹⁹⁹⁸ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 2¹⁹⁹⁸⁻⁹⁹⁹ × 5¹⁹⁹⁸⁻⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 2⁹⁹⁹ × 5⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = (2 × 5)⁹⁹⁹
100⁹⁹⁹ × 5⁻⁹⁹⁹ × 2⁻⁹⁹⁹ = 10⁹⁹⁹
which is a number with 1000 digits,

Best answer gets brainliest and 5 stars
Answer:
No, because 6² + 8² ≠ 12²
Step-by-step explanation:
In a right angled triangle,
Perpendicular² + Base² = Hypotenuse² (pythagoras theorem)
But in the given triangle; 6² + 8² ≠ 12²
36 + 64 ≠ 144
100 ≠ 144
Perpendicular² + base² ≠ hypotenuse²
Thus the given triangle is not right angled.

Adrian, Ben and Charlie share some sweets in the ratio 6:3:8
Charlie got 22 more sweets than Adrian.Work out the total amount of sweets.
Answer:
187 sweets
Step-by-step explanation:
8 units - 6 units = 2 units
2 units = 22 sweets
1 unit = 22 sweets ÷ 2
= 11 sweets
Total amount of sweets = 11 sweets × (6 units + 3 units + 8 units) = 11 sweets × 17 = 187 sweets

The weight of an object on the moon is
1/6 of its weight on Earth. If a moon rock
weighs 20.5 lb on Earth, how much did
the moon rock weigh on the moon?
Answer:
1/6 = 0.16 = 16%
restate the question: 16% of 20.5 is what? multiply: 20.5*.16 = 3.28 now, to find the weight of the object on the moon, subtract 16% from 20.5. 16% of 20.5 is 3.28 20.5-3.28 = 17.22 = 17 22/100 = 17 11/50
the weight of the object is 17 11/50 pounds on the moon.
Find 'x' in the following
First we have to find angle D
As it is a quadrilateral
[tex]\\ \sf\longmapsto <A+<B+<C+<D=360[/tex]
[tex]\\ \sf\longmapsto 45+50+35+<D=360[/tex]
[tex]\\ \sf\longmapsto 130+<D=360[/tex]
[tex]\\ \sf\longmapsto <D=360-130[/tex]
[tex]\\ \sf\longmapsto <D=230°[/tex]
Now
[tex]\\ \sf\longmapsto <D+x=360[/tex]
[tex]\\ \sf\longmapsto x+230=360[/tex]
[tex]\\ \sf\longmapsto x=360-230[/tex]
[tex]\\ \sf\longmapsto x=130°[/tex]
Answer:
x = 130
Step-by-step explanation:
Sum of all the angle of quadrilateral = 360°
50 + 45 + 35 + ∠ADC = 360
130 + ∠ADC = 360
∠ADC = 360 - 130
∠ADC = 230
x = Reflex ∠ADC
= 360 - 230
= 130

write a recrusive rule for the exponential function
f(x)=0.25(2/3)^x
Answer:
f(0) = 0.25 = 1/4
f(x) = f(x-1) × 2/3
Step-by-step explanation:
a0 = 0.25×(2/3)⁰ = 0.25×1 = 0.25 = 1/4
a1 = 0.25×(2/3)¹ = 0.25×(2/3) = 1/4 × 2/3 = 2/12 = 1/6 =
= a0 × 2/3
a2 = 0.25×(2/3)² = 0.25×(4/9) = 1/4 × 4/9 = 4/36 = 1/9 =
= a1 × 2/3
=>
an = an-1 × 2/3, n >= 1
but what about negative x ?
is a0 = a-1 × 2/3 ?
[tex]a - 1 = 0.25 \times {(2 \div 3)}^{ - 1} [/tex]
so, yes, a0 = a-1 × (2/3)
and a-1 = a-2 × (2/3)

the x-intercept of the function f(x)=x^2-81
Answer:
hendoebhdjdbdjjsjsnsnns
jskebeuejbeiwnwvgwvshcc
Answer:
x=9
x=-9
Step-by-step explanation:
The x intercept or roots are x values that makes the f(x) equal 0. So in order words, to find the x intercept. Set the equation equal 0.
[tex] {x}^{2} - 81 = 0[/tex]
We can approach this problem 2 ways
Way 1: Differnece of Squares
Recall that
[tex]a {}^{2} - {b}^{2} = (a + b)(a - b)[/tex]
Since x^2 and 81 are both perfect squares and 81 is negative, we can say that
[tex](x + 9)(x - 9) = 0[/tex]
Set each equation to zero
[tex]x = 9[/tex]
[tex]x = - 9[/tex]
Way 2: Take square root of both sides
[tex] {x}^{2} - 81 = 0[/tex]
[tex] {x}^{2} = 81[/tex]
Next step, take square root of both sides. Square root produce negative and positive solutions so
[tex]x = 9[/tex]
or
[tex]x = - 9[/tex]

A primary trigonometric ratio of an angle is given : tan = 2√5 / 5 . The terminal arm falls in quadrant 3. Find the other 2 primary trigonometric ratios in exact form (no decimals). Rationalize if necessary.
I WILL GIVE BRAINLIEST
Answer:
sin(theta)=-2/3 and cos(theta)=-sqrt(5)/3
Step-by-step explanation:
First of all, as the theta is in 3rd quadrant, all the other ratios will be negative. Second tan(theta)=P/B. So, 2=P and B=sqrt(5), H=sqrt(P^2+H^2)=sqrt(4+5)=3. sin(theta) will be P/H=-2/3 and cos(theta) will be B/H=-sqrt(5)/3
What is the value of x to the nearest tenth? 6.0? 13.4? 30.0? 26.8?
Answer:
26.8
Step-by-step explanation:
2×√(18²-12²)
= 26.8328157..
= 26.8 (rounded to the nearest tenth)
Answer:
26.8
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
12^2+ b^2 = 18^2
144+b^2 = 324
b^2 = 324-144
b^2 = 180
Taking the square root of each side
sqrt(b^2) = sqrt(180)
b = 13.41640
We know b = 1/2x
2b =x
2(13.41640) =x
26.83281573 =x
26.8

Answer:
[tex](x+1)^2+(y+4)^2=9\\[/tex]
Step-by-step explanation:
The general format for the equation of a circle is the following:
[tex](x-h)^2+(y-k)^2=a^2\\[/tex]
Where [tex](h,k)[/tex] is the center of the circle and ([tex]a[/tex]) is the circle's radius. Please note, that the circle ([tex](x-h)^2+(y-k)^2=a^2\\[/tex]) has a center that is (h) units to the right of the origin, and (k) units above the origin.
The given circle has a center at [tex](-1,-4)[/tex], moreover, its radius is (3) units. Therefore, one must substitute these points into the equation of a circle and simplify to find its equation:
[tex](x-h)^2+(y-k)^2=a^2\\[/tex]
[tex](x-(-1))^2+(y-(-4))^2=(3)^2\\[/tex]
[tex](x+1)^2+(y+4)^2=9\\[/tex]
Answer:
Step-by-step explanation: Let's first determine the center of the circle
which is represented by the red dot and it has the coordinates (-1, -4).
The radius of the circle is a segment that joins the center of the
circle to a point on the circle and all radii of a circle are congruent.
The radius of the circle shown here is 3.
Now, the equation of a circle is (x - h)² + (y - k)² = r² where
(h, k) is the center of the circle and r is the radius.
Now we plug all our given information into the formula.
So we have [x - (-1)]² + [y - (-4)]² = (3)².
Notice that I changed the parentheses in the formula to brackets
so that we wouldn't be dealing with too many sets of parentheses.
Changing the brackets back to parentheses,
our equation is (x + 1)² + (y + 4)² = 9.

The domain of a function can be represented by which one of the following
options?
A. a set of F(x) values
B. a set of both input and output values
C. a set of input values
D. a set of output values
Answer: C. a set of input values
The domain is the set of allowed x values, aka input values.
With fairly many domain problems, one thing to look out for are things like potential division by zero issues. For example, if you had the function f(x) = 2/(x-3), then we want to avoid the denominator x-3 from being zero. Because x = 3 makes x-3 equal to zero, this means we must kick x = 3 out of the domain; however, any other real number will work. This example function therefore has the domain of any real number but 3.
Square roots are another thing that often comes up with domain problems. One example could be g(x) = sqrt(x+5). We'd want the x+5 to never be negative. Solving [tex]x+5 \ge 0[/tex] leads to [tex]x \ge -5[/tex] to tell us what set of input x values we can plug in: namely anything -5 or larger.
Other types of domain problems can occur, but those two types are most common in my experience.
