The radius of X² y² 16 is 4.
X² y² 16 is a circle equation. To solve for the radius, we need to divide both sides by 4, then take the square root of both sides. So, 16/4 = 4 and √16 = 4. Therefore, the radius of X² y² 16 is 4. As a reminder, the equation for the radius of a circle is r = √(x² + y²). Therefore, when solving for the radius of a circle, the first step should be to divide both sides of the equation by 4 and then take the square root of both sides.

Answer:
The geometric sequence given is:
3, 9, and 27
When provided with a geometric sequence we must first calculate the common ratio
r is obtained by dividing a term by its preceding term.
1) 9
---- = 3
3
2) 27
---- = 3

Answer: 3.8
Step-by-step explanation:
First, solve 9.30 x 10^7 to find the length of an astronomical unit.
10^7 = 10000000
9.30x10000000=93000000 miles
next, solve for the distances the sun is from Jupiter and Mars,
10^8 = 100000000
1.42x100000000=142000000 miles
4.84x100000000=484000000 miles
next, subtract the distances
484000000-142000000=342000000 miles
then, divide the sum by 93000000 to find the amount in astronomical units.
342000000/93000000=3.677419
finally, round to the nearest hundred

Writing the Standard Form of a Line
Try it
Write the equation of the line that passes through the points (8, -1) and (2,-5) in standard form, given that the point
slope form is y + 1 = 2/3 (x – 8).
____x + ____y = ____
Answer:
[tex]2x-3y = 19[/tex]
Step-by-step explanation:
In standard form, represented by the formula [tex]Ax+By=C[/tex], all the constants and coefficients of the terms are integers, the terms have no common factors (besides 1), and the number in place of A is positive. Knowing this, convert the equation to standard form like so:
[tex]y+1=\frac{2}{3} (x-8)\\y+1 = \frac{2}{3} x-\frac{16}{3} \\-\frac{2}{3} x+y+1 = -\frac{16}{3} \\-\frac{2}{3}x+y = -\frac{16}{3} -1\\-\frac{2}{3} x+y = -\frac{16}{3} -\frac{3}{3} \\-\frac{2}{3} x+y = -\frac{19}{3} \\2x-3y = 19[/tex]
8. Coffee Country City Council has decided to build a new road to connect Main Street
and Lincoln Lane (see the drawing). If construction costs $25,000 per mile, how much
will it cost?
Main Stream
3 mil
Lincoln Ln
1.5 miles-
NEW ROAD
Answer:
easy just pull put calculator and add 25,000 with 3 mil
Step-by-step explanation:
Answer:
Cost 64951.91
Step-by-step explanation:
We are to assume that the new road and Lincoln Lane meat at right angles. If that is true we can use the Pythagorean Theorem.
Givens
a = 1.5 miles
b = ?
c = 3 miles
Cost per mile = 25000
Solution
a^2 + b^2 = c^2
1.5^2 + b^2 = 3^2
2.25 + b^2 = 9
b^2 = 9 - 2.25
b^2 = 6.75
sqrt(b^2) = sqrt(6.75)
b = 2.5981
Cost
1 mile costs 25000
2.5981 costs x
1/2.5981 = 25000 / x Cross Multiply
x = 2.5981 * 25000
x = 64951.91

Solve for x in the parallelogram below:
X=??
Answer:
x = 4
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, sum to 180°, so
14x + 6 + 118 = 180
14x + 124 = 180 ( subtract 124 from both sides )
14x = 56 ( divide both sides by 14 )
x = 4
Answer:
x = 4Step-by-step explanation:
Adjacent angles of a parallelogram are supplementary
14x + 6 + 118 = 18014x + 124 = 18014x = 180 - 12414x = 56x = 56/4x = 4
Find a30 of the arithmetic sequence:
−17,−7,3,13,...
Answer:
a₃₀ = 273
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 17 and d = a₂ - a₁ = - 7 - (- 17) = - 7 + 17 = 10 , then
a₃₀ = - 17 + (29 × 10) = - 17 + 290 = 273
What is the length of the unknown leg in the right triangle?
Answer:
15m
Step-by-step explanation:
a^2 + b^2 = c^2
a=?
b = 20m
c = 25m
a^2 + (20m)^2 = (25m)^2
a^2 + 400m^2 = 625m^2
a^2 = 625m^2 - 400m^2 = 225m^2
a = 15m

Natalie invests $5,632 in a retirement account with a fixed annual interest rate of 2% compounded 12 times per year. What will the account balance be after 16 years?
A) $8,398.46
C) $7,753.92
B) $8,610.85
D) $7,910.43
Answer:
C) $7,753.92
Step-by-step explanation:
Given data
Principal= $5,632
Rate=2%
n= 12
Time = 16 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 5632(1+0.02/12)^12*16
A=5632(1+0.02/12)^12*16
A= 5632(1+0.00166)^12*16
A= 5632(1.00166)^12*16
A= 5632(1.00166)^192
A=5632*1.375
A=$7744
Hence the approximate amount is C) $7,753.92

2x-3y=-1
y=x-1
Let's solve your system by substitution.
2x−3y=−1; y=x−1
Rewrite equations:
y=x−1;2x−3y=−1
Step: Solve
y= x−1
Step: Substitute x−1 for y in 2x−3y=−1:
2x−3y=−1
2x−3(x−1)=−1
−x+3=−1(Simplify both sides of the equation)
−x+3+−3=−1+−3(Add -3 to both sides)
−x=−4−x−1=−4−1
(Divide both sides by -1)
x=4
Step: Substitute4forxiny=x−1:
y=x−1
y=4−1
y=3(Simplify both sides of the equation)
Answer:
x=4 and y=3

Stay Cold,
Brook
Answer:
(4,3)
Step-by-step explanation:
Being that the y variable is isolated in the second equation, the other side of that equation can be substituted for y in the first equation.
[tex]2x - 3(x - 1) = - 1[/tex]
Now simplify for x.
[tex]2x - 3x + 3 = - 1 \\ - x = - 4 \\ x = 4[/tex]
Now with that, insert the x value in for x in the second equation.
[tex]y = (4) - 1 \\ y = 3[/tex]
Now the correct answer is (4,3)

A trapezoid has a height of 6 inches, an area of 120 inches, and one base measuring 14 inches. Find the length of the other base
Answer:
26 inches
Step-by-step explanation:
Area of a trapezoid = [tex]\frac{1}{2}[/tex](a + b) x h
a and b = 2 parallel sides
h = height
120 = 0.5(14 + b) x 6
120 = 3 x (14 +b)
Divide both sides of the equation by 3
120/3 = 14 + b
40 = 14 + b
Collect like terms
b = 40 - 14 = 26inches
