Bill bought a new cellular phone. His monthly bill will be $34.99 each month which includes 100 minutes of use. Additional minutes will cost $0.23 per minute. Write an equation that represents the cost of the bill C in terms of m, which is the number of minutes used ABOVE the 100 that are included in the base price. a. C = 34.99(m – 100) + 0.23 c. C = 0.23m b. C = 0.23m + 34.99 d. C = 0.23(m – 100) + 34.99

[ad_1]

Answer:

d. C = 0.23(m – 100) + 34.99

Step-by-step explanation:

Let C = X + Y, where

C = Cost of the bill in terms of m

X = First term of the equation

Y = Second term of the equation

X = add additional minutes to $ 0.23 minus the 100 minutes of use allocated.

X = 0.23 (m – 100)

Y = Base price monthly will be $ 34.99

Y = 34.99

C = X + Y

C = 0.23 (m – 100) + 34.99

Note: The only possible answer is 0.23 (m – 100) + 34.99, but we must assume that “m” is greater than or equal to 100, that is, Bill consumes at least his 100 minutes assigned by the base price.

Hope this helps!

Given the exponential equation 2x = 128, what is the logarithmic form of the equation in base 10?

[ad_1]

Answer:

log_{2}128= frac{log_{10} 128}{log_{10} 2}.  

Step-by-step explanation:

Given : 2^{x} = 128.

To find :  what is the logarithmic form of the equation in base 10

Solution : We have given that 2^{x} = 128.

By th change base rule ( inverse of exponential function )

a^{b} = c is equal to  log_{a}(c) = b

Then 2^{x} = 128 in to logarithm form  log_{2}(128) = x.

Then in to the base 10 logarithmic form.

By the change of base formula log_{b}a= frac{log_{10} a}{log_{10} b}.

Then , log_{2}128= frac{log_{10} 128}{log_{10} 2}.  

Therefore, log_{2}128= frac{log_{10} 128}{log_{10} 2}.

The length of the base of a rectangular pyramid is tripled, the width of the base remains the same, and the height of the pyramid is divided by 7. What volume formula reflects these changes?

[ad_1]

Answer with Step-by-step explanation:

The volume of a rectangular pyramid is given by:

V=lbh/3

Where l is the length

b is the breath  

and h is the height.

Now, l’,b’ and h’ be new length,breath and height

Then, l’=3l

b’=b

and h’=h/7

New volume=V’=l’b’h’/3

                         = dfrac{3ltimes btimes dfrac{h}{7}}{3}

                         = dfrac{lbh}{7}

Hence, Volume formula which reflects these changes is:

dfrac{lbh}{7}

Check the picture below

if the width or base of the rectangle is 3 units, that means the diameter of the semi-circle is 3, and thus the radius is half that, notice the red radius line

the area of the figure is the area of the rectangle 3×4, plus the area of the semi-circle

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage. Which type of mutation causes sickle cell anemia? A)silent B)missense C)insertion D)frameshift

[ad_1]

The right option is; B)missense

Missense mutation is the type of mutation that causes sickle cell anemia

A missense mutation is a type of nonsynonymous substitution in which the change of a single nucleotide (base pair) influences the genetic code and results in a codon that code for a different amino acid. This type of mutation can affect the function of the protein, and it is responsible for human diseases such as, sickle-cell anemia and Epidermolysis bullosa.

Which type of mutation is responsible for the change in the iRNA base? Options: A) silent B) missense C) nonsense D) insertion Need answer ASAP

[ad_1]

A) silent – means that the letter changes but the outcome is the same
B) missense – means that it changes just one base pair
C) nonsense – changes something to a stop code and messes up the whole chain
D) insertion – adds a letter

so its A because you said “

but during translation the iRNA strand still creates the same protein” so even though the mutation occurred the outcome was still the same.

If Denise wanted to create a function that modeled an exponential function with base of 12 and what exponents were needed to reach specific values, how would she set up her function? f(x) = x12 f(x) = log12x f(x) = 12x f(x) = logx12

[ad_1]

Denise creates the exponential function g(x)=12 ^{x}

assume she want to find for what value of x, her function reaches the value, 3, or 8.2, or any value a (larger than 0)

so she shants to solve 12 ^{x}=a   (“for what value of x, is 12 to the power of x equal to a?”)

this expression is equivalent to x=log_1_2(a)

(so 12 to the power of x is a, for x=log_1_2_(a))

we can generalize this result by creating a function f.

In this function we enter x, the specific value we want to reach. f will calculate the exponent needed, in the following way:

f(x)=log_1_2(x)  

(example: we want to calculate at which value is  12^{x} equal to 5?
answer: f(x)= log_1_2(5),

check: 12^{log_1_2(5)} =5, which is true, by properties of logarithms)

Answer: log_1_2(x)       (B)

What is the height of a square pyramid that has a volume of 32 cubic feet and a base length of 4 feet

[ad_1]

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

d=sqrt{(c-a)^2+(d-b)^2}.

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

d=sqrt{(x-8)^2+(y-9)^2}.

Since, distance between A and B is 10 units, so

d = 10.

Therefore,

10=sqrt{(x-8)^2+(y-9)^2}.

Thus, the correct statement is

10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared.

Option (C) is correct.

Find the height of a triangle whose base is 2 square root 2 inches and area is 8 square root 6 square inches.

Answer:  The correct option is (C). 10 = square root of the quantity of x minus 8 all squared plus y minus 9 all squared

Step-by-step explanation:  Given that the segment AB has point A located at (8, 9). The distance from A to B is 10 units.

We are to select the correct option that could be used to calculate the coordinates for point B.

Let, (x, y) be the co-ordinates of point B.

According to distance formula, the distance between two points (a, b) and (c, d) is given by

Therefore, the distance between the points A(8, 9) and B(x, y) is given by

Since, distance between A and B is 10 units, so
