Answer:
Arithmetic.
Step-by-step explanation:
See if it's arithmetic:
2/3 - 1/3 = 1/3
1 - 2/3 = 1/3
4/3 - 1 = 1/3
- common difference of 1/3 so it's arithmetic.
A scientist looks at a bacterium and a virus in a lab. The bacterium has a diameter of 10 Superscript negative 6 meters. The virus has a diameter of 10 Superscript negative 7 meters. Which statement accurately compares the sizes of the specimens? The diameter of the bacterium is 10 times greater than that of the virus. The diameter of the bacterium is StartFraction 1 Over 100 EndFraction times as great as that of the virus. The diameter of the virus is 10 times greater than that of the bacterium. The diameter of the virus is StartFraction 1 Over 100 EndFraction times as great as that of the bacterium.
Answer: A
Step-by-step explanation:
The diameter of the bacterium is 10 times greater than that of the virus.
The statement that accurately and precisely compares the sizes of the specimens can be seen in the first option.
What is a Superscript?A Superscript is used for the representation of a power at which a number is being raised to. In essence, if we have [tex]a^n[/tex];
a is the base number n is the superscriptFrom the given information;
The diameter of the bacterium = [tex]\mathbf{10^{-6}}[/tex]The diameter of the virus = [tex]\mathbf{10^{-7}}[/tex]We should note that as the exponent increase by -1, it takes an addition [tex] \mathbf{\dfrac{1}{10}=10^{-1}} [/tex]
Therefore, we can say that the diameter of the bacterium is 10 times greater than that of the virus.

1. What are the coordinates of the vertex of the graph? Is it a maximum or minimum?
Answer:
Hi there!
The correct answer is: (0,1) maximum
Step-by-step explanation:
vertex: the point where the parabola crosses its axis of symmetry.
when the graph is concave down, maximum
when the graph is concave up, minimum
Answer:
Coordinates of the vertex: (0, 1), and it is a maximum.
this corresponds to the second of the listed answer options.
Step-by-step explanation:
Notice that the vertex of the parabola is at the very top of the curve, and corresponds to the maximum value that the coordinate "y" can reach for the parabola (y = 1)
The position of that vertex is exactly at the point where x = 0 and y = 1, so this can be written as:
(0, 1)
Given f(g(x)) = 15x+1 and f(x) = 5x+1. What is g(x)?
Please answer quickly!!
Suppose you are given the two functions f (x) = 2x + 3 and g(x) = –x2 + 5. Composition means that you can plug g(x) into f (x). This is written as "( f o g)(x)", which is pronounced as "f-compose-g of x". And "( f o g)(x)" means " f (g(x))".

Step-by-step explanation:
2x - 3/4 + x = 2x + 3/2 + 9
- 3/4 + x = 3/2 + 9
- 3/4 + x = 21/2
x = 21/2 + 3/4

What is the volume of a sphere with a radius of 21 units?
A. 9261 pie units 3
B. 12,348 pie units 3
C. 588 pie units 3
D. 37,044 pie units 3
Answer:
B
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius ), thus
V = [tex]\frac{4}{3}[/tex]π × 21³
= [tex]\frac{4}{3}[/tex]π ×9261 = [tex]\frac{4(9261)}{3}[/tex]π = 12348π units³ → B
Answer: B: 12,348π units³ which is 38,772.72 units³
Step-by-step explanation:
The formula of the volume of a sphere is V = [tex]\frac{4}{3}[/tex]πr³
Since we know that the radius is 21, we can fill in the given numbers:
V = [tex]\frac{4}{3}[/tex]π(21)³
Now, the new formula is V = [tex]\frac{4}{3}[/tex]π(9,261) = 38,772.72

In a right triangle, one leg is 20 cm and the hypotenuse is 30 cm. To the nearest hundredth of a cm, find the length of the missing leg. Formula and diagram required. Include units in your answer.
Answer:
Step-by-step explanation:
Use Pythagoras’ theorem
square of hypotenuse = sum of squares of two other sides
let the missing side be d
30^2 = 20^2 + d^2
600 = 400 + d^2
d^2 = 200
d = square root of 200
d = 14.142 cm
Answer:
22.36
Step-by-step explanation:
For this question we need to utilise Pythagoras theorem. Pythagoras theorem states that a² + b² = c² so the sum of the leg's squared will equal the hypotenuse squared. In this question we are given the hypotenuse so we will have to rearrange the equation to find the value of the leg,
→ a² + b² = c²
⇒ Substitute in the values
→ 20² + b² = 30²
⇒ Simplify
→ 400 + b² = 900
⇒ Minus 400 from both sides to isolate b²
→ b² = 500
⇒ Square root both sides to find the value of the leg
→ b = 22.360679775 cm
The length of the missing leg is 22.36 cm to nearest hundredth considering one leg is 20 cm and the hypotenuse is 30 cm.

Which is the equation in slope-intercept form for the line that passes through (3, 7)
and is perpendicular to 3x - 5y = 8?
Answer:
[tex]y = - \frac{5}{3} x + 12[/tex]
Step-by-step explanation:
First, rewrite the given equation in the form of y=mx+c.
m is the gradient while c is the y-intercept.
3x-5y=8
5y= 3x -8
[tex]y = \frac{3}{5} x - \frac{8}{5} [/tex]
Thus, the gradient of the given equation is ⅗.
The product of the gradients of perpendicular lines is -1.
(gradient of line)(⅗) = -1
gradient of line= -1 ÷⅗
gradient of line= [tex] - \frac{5}{3} [/tex]
[tex]y = - \frac{5}{3} x + c[/tex]
To find the value of c, substitute a coordinate.
When x=3, y=7,
[tex]7 = - \frac{5}{3} (3) + c[/tex]
7= -5 +c
c= 7+5
c= 12
Hence, the equation of the line is [tex]y = - \frac{5}{3} x + 12[/tex].

Consider the figure shown on the coordinate plane. What are the coordinates of the midpoint of line segment CB?
A) (0, 3/2)
B) (1, 0)
C) (3/2,0)
D) (2, 1)
Answer:
im pretty sure its C (2/3, 0) actually
Answer the questions attached:
1. I'm not completely sure, but these angles seem to be complementary, meaning they add up to 90°. Since 75° + x = 90°, x = 15°.
2. These lines seem to be parallel. ∠4 ≅ ∠1 because they are vertical angles, ∠5 ≅ ∠1 because they are corresponding angles, and because ∠8 ≅ ∠4 (corresponding angles), ∠8 ≅ ∠1 as well. The final answer is ∠4, ∠5, and ∠8. Hope this helps!
