Answer: n=7

Step-by-step explanation:

We are given an equation : \dfrac{35}{49}=\dfrac{5}{n}

To find n , we multiply n on both the sides , we get

\dfrac{35}{49}\times n=\dfrac{5}{n}\times n

\Rightarrow\ \dfrac{35n}{49}=5

Now, we multiply 49  on both sides , we get

\dfrac{35n}{49}\times49=5\times49

35n=245

Divide both sides by 35, we get

\dfrac{35n}{35}=\dfrac{245}{35}\\\\\Rightarrow\ n=7

What is the vertex of the function f(x) = x2 + 3x + ?
guapka [62]

The vertex of the function is at x = -3/2. We cannot find the y value with an incomplete equation.


To find the x value of a vertex, we use the equation -b/2a, in which a is equal to the coefficient of x^2 (in this case 1) and b is equal to the coefficient of x (in this case 3).


-b/2a

-3/2(1)

-3/2


This gives us that value. To find the y value, you would plug this into the equation. Since this equation is not complete, you cannot do that yet.

The number of bags of mulch you need to cover a planting area varies jointly with the area to be mulched (a) in sq ft and the de
Lena [83]

Answer:

  22 2/9

Step-by-step explanation:

When z "varies jointly" with x and y, it can be described by the formula

   z = kxy

Here, we have bags of mulch (n) varying jointly with area (a) and depth (d), both in feet. The given information can let us find the value of k.

  n = kad

  10 = k·(120)(1/4)

  10/30 = k = 1/3 . . . . . divide by the coefficient of k

Now, we can fill in the other values of interest.

  n = (1/3)·(200)·(1/3) = 200/9

  n = 22 2/9

You need 22 2/9 bags of mulch to cover 200 ft² to a depth of 4 inches.

_____

<em>Comment on the problem</em>

This problem requires the formula be written with both area and depth expressed in feet, yet it gives depth in inches. The formula can also be written using depth in inches. In that case, k = 1/36.

Given g(x)=Squareroot x-4 and h(x)=2x-8, what is g(h(10))
yan [13]

Answer:

g(h(10)) = 2\sqrt 2

Step-by-step explanation:

Given

g(x) = \sqrt {x - 4

h(x) = 2x - 8

Required

g(h(10))

First, calculate g(h(x))

We have:

g(x) = \sqrt {x - 4

This gives:

g(h(x)) = \sqrt {h(x) - 4

Substitute h(x) = 2x - 8

g(h(x)) = \sqrt {2x - 8 - 4

g(h(x)) = \sqrt {2x - 12

Substitute x = 10

g(h(10)) = \sqrt {2*10 - 12

g(h(10)) = \sqrt {20 - 12

g(h(10)) = \sqrt {8\\

Split

g(h(10)) = \sqrt {4} * \sqrt 2

This gives

g(h(10)) = 2\sqrt 2

Rashid [163]

Answer:

19.55\pm2.145

Step-by-step explanation:

We use the equation \bar x\pm z^*\sigma/\sqrt n, where \bar x=19.55, \sigma=6.33, n=41, and z^*=2.17. We obtain z^* from the z-score of a 0.97 confidence level.
