A single Rhinovirus is 2 × 10-8 meters long, and a single E. coli bacterium is 2 × 10-6 meters long. How many times larger is an E. coli bacterium than a Rhinovirus?
Multiply it by using scientific notation then multiply 2X0.00000010 and compare it to the coil which is 2X0.000010
Answer:
E coli bacterium is 200times larger than Rhinovirus
Step-by-step explanation:
Length of a single Rhinovirus is 2×10^-8m
Length of E coli bacterium is 2×10^-6m
This shows that E coli is larger than Rhinovirus.
To determine the number of times the E. coli bacterium is larger than a Rhinovirus, we will divide the length of E coli bacterium by that of single Rhinovirus to have:
2×10^-6/2×10^-8
= 2×10^(-6-(-8))
= 2×10^-6+8
= 2×10²
= 200
This shows that E coli bacterium is 200times larger than Rhinovirus

F(x) = x^2. What is g(x)?
Answer:
The correct answer is C. g(x) = 1/4x^2
Step-by-step explanation:
In order to determine if the graph fits, take the point that is given on the parabola and see if it fits the equation. To do that we plug it in and see if it gives a true statement.
(2, 1)
g(x) = 1/4x^2
1 = 1/4(2)^2
1 = 1/4(4)
1 = 1 (TRUE)
Answer:
C, g(x) = 1/4x²
Step-by-step explanation:
the parent function of g(x) is the function f(x) = x² as shown on the graph
with the coefficient 1/4 in front of the parent function, we can determine its transformation.
it is a vertical shrink by 1/4 of the original graph. the reason why we know this is because a vertical shrink/stretch has a coefficient on the outside of the parent function (as shown in g(x)) and if we follow the rule:
b > 0 < this is a vertical stretch
b < 0 < this is a vertical shrink
b in this function is 1/4, which is less than 0

What is the messure of angle 4
Answer:
m∠4 = 40°
Step-by-step explanation:
Using the vertical angle theorem we can find that...
m∠6 ≅ m∠7
[tex]11x+8=12x-4 \\ \\ x=12[/tex]
[tex]11(12)+8 \\ 132+8 \\ 140[/tex]
Using this, we know that angle 6 and 8 are supplementary so...
m∠6 + m∠8 = 180°
140° + m∠8 = 180°
m∠8 = 40°
Then, we can use the corresponding angle theorem to find that...
m∠8 ≅ m∠4
m∠4 = 40°
the measure of angle 4 is 40
Brett painted three walls. Each wall was 9 ft tall and 12 ft long. How much wall area did he paint
Answer:
First we need to calculate the are of each wall, since we alredy knew the length (l) and the width (w) which is the height of the wall in this case:
A = wl = 9 . 12 = 108 (ft²)
We also know that he painted 3 walls, we need to multiply our first result by 3, in other words, the area of wall that Brett painted is the sum of the area of three walls: 108 . 3 = 324 (ft²)
Answer:
324 ft^2
Step-by-step explanation:
ok so to calculate the area its A = wl (width x length)
9 x 12 = 108 ft^2
buuuuuut since we have 3 walls were going to have to multiply it by three as cuz 108 ft^2 is the outcome of one wall
108 ft x 3 = 324 ft^2

Solve 3^x+1 = 15 for x using the change of base formula log base b of y equals log y over log b
Answer:
x= 1.46497
Step-by-step explanation:
[tex]3^{x+1} = 15[/tex]
To solve this , first we convert the exponential form in to log form
[tex]if \ a^x=b \ then \ log_a(b)=x[/tex]
[tex]3^{x+1} = 15[/tex] becomes [tex]log_3(15)= x+1[/tex]
now we apply change of base formula to remove base 3
[tex]log_b(y)= \frac{log y}{log b}[/tex]
like that log_3(15) becomes
[tex]log_3(15)= \frac{log 15}{log 3}[/tex]
[tex] \frac{log 15}{log 3}= x+1[/tex]
2.46497=x+1
subtract 1 from both sides
x= 1.46497
Answer:
The value of x is 1.46.
Step-by-step explanation:
Given : Equation [tex]3^{x+1}=15[/tex]
To find : Solve for x using the change of base formula log base b of y equals log y over log b ?
Solution :
Equation [tex]3^{x+1}=15[/tex]
Applying the logarithmic property,
[tex]a^x=b\Rightarrow \log_a(b)=x[/tex]
[tex]3^{x+1}=15\Rightarrow \log_3(15)=x+1[/tex]
Applying change base formula in LHS,
[tex]log_b(y)= \frac{log y}{log b}[/tex]
[tex]\frac{log 15}{log 3}=x+1[/tex]
[tex]2.46=x+1[/tex]
[tex]x=2.46-1[/tex]
[tex]x=1.46[/tex]
Therefore, the value of x is 1.46.

A cylindrical plastic pipe’s length is 12 cm and it’s radius is 2.5 cm. To the nearest tenth, what is the volume of the pipe?
Answer:
V = 235.6 cm³
Step-by-step explanation:
the formula for the volume of a cylinder of radius r and length h is
V = πr²h.
Here, r = 2.5 cm and h = 12 cm, so the volume is:
V = π(2.5 cm)²(12 cm) = 75π cm³
To the nearest tenth, this volume would be V = 235.6 cm³
Answer:
volume = 235.7 cm³
Step-by-step explanation:
To find the volume of the cylindrical plastic pipe, we simply use the formula:
volume of a cylinder = π r ² h
where r is the radius , and h is the height
From the question above, radius r = 2.5cm h =12 cm and π is a constant which is always equal to [tex]\frac{22}{7}[/tex] unless specified otherwise.
Now all we need to do is to insert our values into the formula;
volume of a cylinder = π r ² h
volume of a cylinder = [tex]\frac{22}{7}[/tex] × 2.5² × 12
= [tex]\frac{22}{7}[/tex] × 6.25 × 12
= [tex]\frac{1650}{7}[/tex]
= 235.714
≈235.7 cm³ to the nearest tenth
Therefore the volume of the cylindrical plastic pipe is 235.7 cm³
