Answer:

Rs.16

Step-by-step explanation:

Divide the cost of Rs.96 by 12 then multiply by 2

cost of 1 pencil = Rs.96 ÷ 12 = Rs.8

cost of 2 pencils = 2 × Rs.8 = Rs.16

Can someone help answer and explain to me how to solve this? log (lowercase 6) 1/36
MissTica
Answer: The log simplifies to -2

-------------------------------------------
-------------------------------------------

Explanation:

We will use the log rule that log(x^y) = y*log(x). Call this log rule 1. This log rule basically allows us to pull the exponent down.

Another log rule that we will use is \log_x\left(x\right) = 1 where x is any positive real number but x = 1 is NOT allowed. Call this log rule 2.

Because 36 = 6^2, this means that 1/36 = 6^(-2)

-------------

So,

\log_6\left(\frac{1}{36}\right)=\log_6\left(\frac{1}{6^2}\right)

\log_6\left(\frac{1}{36}\right)=\log_6\left(6^{-2}\right)

\log_6\left(\frac{1}{36}\right)=-2*\log_6\left(6\right) Use log rule 1 (see above)

\log_6\left(\frac{1}{36}\right)=-2*1 Use log rule 2 (see above)

\log_6\left(\frac{1}{36}\right)=-2 

This means that the given expression simplifies to -2

You can use a calculator to type in "log(1/36)/log(6)" without quotes and you should get -2 as the answer

Convert the function from vertex form to standard form. <br> -1/2(x + 2)^2 - 3
Andrej [43]

Answer:

-\frac{1}{2}x^2-2x-5 [\tex]Step-by-step explanation:To convert it to standard form, all you need to do is expand the square and simplify. This would get us to: [tex]-\frac{1}{2}(x^2 + 4x + 4) - 3 which simplifies further to -\frac{1}{2}x^2-2x-2-3 and combine the -2 and -3 to get [tex] -\frac{1}{2}x^2-2x-5 [\tex]

Hope this helps :)

Allen rents a truck for 45 dollars plus .36 cents for every mile that he drives the truck. Write an equation that models this li
enot [183]

Answer:

This is a linear equation of the form y = mx + b, where m is the rate of change and b is the y-intercept, also known as the value of y when x = 0.  Our independent variable is the number of miles we travel, and we will call that x.  If we pay .20 per mile, and miles is "x", we represent that as .20x.  The 70 is the amount we will pay per day even if we drive 0 miles.  Therefore, the equation is:

y = .20x + 70.

I cannot graph this for you here.

We can choose a number of miles, say 100, and solve for our cost:

y = .20(100) + 70

y = 20 + 70

y = 90

We can expect to pay $90 if we drive 100 miles in a day.

A carpenter is building a rectangular bookcase with diagonal braces across the back as shown the Carpender knows that angle ADC
Rudik [331]
I think I have the diagram right.
Let ADB = x, and then BDC = x+32.
x+x+32 = 90
2x = 58
x = 29 = ADB
so BDC = 61

Can u help me plz thanks
Mrrafil [7]
1. x = -4 ; f(x) = -(-4) = 4
2. x = -3 ; f(x) = 2(-3) + 1 = -5
3. x = 0 ; f(x) = 2(0) + 1 = 1
4. x = 2 ; f(x) = 2 + 3 = 5
5. x = 5 ; f(x) = 5 + 3 = 8
