The diameter of a circle is 15 m. Find the circumference \textit{to the nearest tenth}to the nearest tenth.
Given that, the diameter of the circle 15 m. The circumference of a circle is 2πr. Then the circumference of the circle with the given diameter is 47.1 m.
What is circumference of a circle?Circumference of a circle is also called its perimeter and it describes the overall area of the surrounding circular path. The distance round a circle is its circumference, but this cannot be used as a definition if, as in many elementary treatments, distance is defined in terms of straight lines.
In these conditions, the limit of the perimeters of inscribed regular polygons may be described as the circumference of a circle as the number of sides increases without constraint. When describing abstract geometric forms as well as measuring real-world things, the term circumference is frequently used.
It is given that, the diameter of the circle = 15 m
radius r = diameter/ 2 = 15 m/ 2 = 7.5 m
circumference of circle = 2 π r
= 2 × 3.14 × 7.5 m
= 47.1 m

the sum of the square of two consecutive positive integers is 85. Write a quadratic equation
Answer:
2x^2 + 2x - 83 = 0
Step-by-step explanation:
Consecutive integers differ by 1
Let the first number be x
The next will be (x+1)
The sum of the squares of these two numbers is 85
so we have;
x^2 + (x + 1)^2 =85
= x^2 + x^2 + 2x + 2 = 85
2x^2 + 2x + 2-85 = 0
2x^2 + 2x - 83 = 0

Given the first term and the common ratio of a geometric
sequence find the first five terms and the explicit formula.
a1 = - 4, r = 6
Answer:
331776
Step-by-step explanation:
The formula for geometric
sequence is given below
ar^n-1
Where a= first term, r= common ratio
From the question, a1 = - 4, r = 6 , n= 5
Then if we substitute, we have
ar^n-1
5th term= ar^n-1
= (-4×6)^(5-1)
=-24 ^ 4
=331776
Hence, the first five terms is =331776
The formula is 5th term= ar^(5-1)

What is the equation of the graph below?
А
y = 2(x + 4)2 – 2
B
y = (x – 4)2 – 2
C y = 2(x - 4)2 – 2
D
y = 2(x – 4)2 + 4
Answer:
f(x) = 1(x - 4)^2 - 2
Step-by-step explanation:
Recall that the vertex form of the equation of a parabola is
f(x) = a(x - h)^2 + k, where (h, k) is the vertex and a is a scale factor which stretches or compresses the graph vertically.
Looking carefully at the graph, we see that h must be 4 and k must be -2.
Thus, the equation of this parabola is f(x) = 1(x - 4)^2 - 2 (which matches Answer B)
What is 2/5 y + 1/5 x -0.2y-6+(-2)
Answer:
[tex]\frac{y}{5} + \frac{x}{5}-8[/tex]
Step-by-step explanation:
1) Simplify 2 /5y to 2y/5.
[tex]\frac{2y}{5} + \frac{1}{5} x-0.2 y-6-2[/tex]
2) simplify 1/5x to x/5.
[tex]\frac{2y}{5} +\frac{x}{5} -0.2y-6-2[/tex]
3) Collect like terms.
[tex](\frac{2y}{5} -0.2y) + \frac{x}{5} +(-6-2)[/tex]
4) Simplify.
[tex]\frac{y}{5}+ \frac{x}{5} -8[/tex]
Therefor, the answer is y/5 + x/5 -8.

The red arcs mean those angles are the same.
When two angles are the same the corresponding sides are also the same.
5. X = 8
6. X = 11
7. 2x-16 = 8
Add 16 to both sides:
2x = 24
Divide both sides by 2:
X = 12
8. X + 19 = 8
Subtract 19 from both sides:
X = -11
