solong [7]3 years ago
8 0
So 36% of x is 18
percent is parts out of 100
36%=36/100=0.36
'of' can be translated as muitiply
0.36 times x=18
divide both sdies by .36
x=50
the number is 50

What is the initial value of the equation shown?<br><br> y = −7x − 6
Gwar [14]

Answer:

y = -6

Step-by-step explanation:

Given

y = -7x-6

Required

Determine the initial value

The initial value of any equation is the point where

x = 0

Substitute 0 for x in y = -7x-6

y = -7 * 0 - 6

y=0-6

y = -6

<em>Hence, the initia; value is -6</em>

How do I do this? It is a regular hexagon with a height of 30. We have to find the perimeter of it.
Sliva [168]

Answer:

The radius of a hexagon is called the apothem, which in this case is 15.

We need to know the side length which is found by the equation:

side length = apothem * 2 * (tan (180 / #sides))

side length = apothem * 2 * (tan (180 / 6))

side length = 15 * 2 * (tan (30 degrees))

side length = 30 * .57735

side length = 17.3205

We need the perimeter of the hexagon which equals the side length times six.

perimeter = 6 * 17.3205 = 103.923

(Multiplying and Dividing with Scientific Notation LC)
Assoli18 [71]

The product in scientific notation is 8*10^2

<h3>How to multiply and divide in scientific notation?</h3>

Here we want to find the product between 4*10^6 and 2*10^6, and write that in scientific notation.

First, we can solve the direct product:

(4*10^6)*(2*10^6) = (4*2)*(10^6*10^6)

Here we used the fact that we can multiply in any order we want.

Now we will use the property:

a^n*a^n = a^{n + m}

(4*2)*(10^6*10^6) = 8*10^{6 + 6} = 8*10^12

The correct option is the second one, counting from the top.

!! AP CALCULUS AB !!<br> find the limit of [(secx*sinx) + (cscx*cosx)]/(3secx) as x approaches 3pi/2
uysha [10]

f(x)= \frac{\frac{\sin{x}}{\cos{x}}+\frac{\cos{x}}{\sin{x}}}{3\sec{x}}

\frac{\frac{\sin{x}}{\cos{x}}+\frac{\cos{x}}{\sin{x}}}{3\sec{x}} \implies \\ \frac{\sin^2{x}+\cos^2{x}}{\sin{x}\cos{x}}\frac{\cos{x}}{3}\implies \\\frac{1}{\sin{x}\cos{x}}*\frac{\cos{x}}{3}\implies \\ \frac{1}{3\sin{x}}

So,

\lim_{x \rightarrow \frac{3\pi}{2}}{f(x)=f(\frac{3\pi}{2})=\frac{1}{3\sin{\frac{3\pi}{2}}}=-\frac{1}{3}
