Negative 10 over 7 minus one over seventy

Answer:

52.61

Step-by-step explanation:

First let turn 9.6% into a decimal

0.096

Then,

48 x 0.096 = 4.608 {Round} 4.61

48 + 4.61=52.61

Answer:

Answer:

  a. 16.9 m

  b. 4.082 seconds

  c. no

  d. 2.041 seconds

  e. 21.41 m

Step-by-step explanation:

A graphing calculator can help you answer these questions quickly and easily. The graph is attached.

__

Evaluate the function at t=3.

  h(t) = -4.9t^2 +20t +1

  h(3) = (-4.9×3 +20)×3 +1 = 5.3×3 +2 = 16.9

The baton will be at a height of 16.9 meters after 3 seconds.

__

The axis of symmetry of quadratic ax^2+bx+c is located at x=-b/(2a). The point of release and the later point at the same height will be symmetrically located about the axis of symmetry. The peak height will be on the axis of symmetry of the graph. That value of time is ...

  tpeak = -20/(2(-4.9)) = 20/9.8 ≈ 2.041 . . . seconds

The baton will be at the release height again after 2×2.041 = 4.082 seconds.

__

As we saw in part (b), the maximum height will be when t=2.041 seconds. That height is found by evaluating the function for that value of t.

 h(2.041) = (-4.9(2.041) +20)(2.041) +1 = 21.41 . . . meters

The baton will not reach a height of 25 meters.

__

We found this answer in part (b): 2.041 seconds to reach the maximum height.

__

We found this answer in part (c): 21.41 meters is the maximum height.

_____

Additional comment

The time at maximum height is 20/9.8 seconds = 100/49 = 2 2/49 seconds. In general, the answer values shown here are rounded to 4 significant figures. The graphing calculator rounds to 3 decimal places.

0/0 = undefined not 1

Step-by-step explanation: Undefined means there are no solutions possible for the operations in view. The example in question is itself wrong. n/0 is infinite but not undefined. 0/0 is undefined

Answer:

1. x = 6    2. x = 9   3. x = 3

Step-by-step explanation:

Use Intersecting Secants Theorem:

If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.

1.  AC and AD are secants that intersect at point A

So, AB x AC = AE x AD

         [tex]x[/tex] x 15 = 6 x (6 + 9)

             15[tex]x[/tex] = 90

                 [tex]x[/tex] = 6

2.  KM and KN are secants that intersect at point K

So,  KL x KM = KO x KN

 10 x (10 + 8) = [tex]x[/tex] x 20

              180 = 20[tex]x[/tex]

                  [tex]x[/tex] = 9

3.  IG and IF are secants that intersect at point I

So,  IH x IG = IJ x IF

       [tex]x[/tex] x 39 = 9 x (9 + 4)

           39[tex]x[/tex] = 117

               [tex]x[/tex] = 3

  (c)  10 phones

Step-by-step explanation:

The mean is the sum divided by the number of contributors:

  (12 +10 +9 +5 +14 +10 +10)/7 = 70/7 = 10

The mean number of phones sold for the week was 10 phones.

Answer:

Surface Area: 310 square inches.

Step-by-step explanation:

There are two ways to do this:

A) Formula for Surface Area of a Rectangular Prism = 2 * ( l*w + w*h + h*l). Where l is length, w is width & h is height. Based on the question:

l = 10 inch

w = 5 inch

h = 7 inch

Surface Area = 2 * ( 10*5 + 5*7 + 7*10) = 310 square inches.

B) Formula for Area of Rectangle = l*w, where l is length & w is width.

Look at the picture, I have marked the corners O,P,Q,R,S,T,U,V,W,X,Y,Z

If we calculate the Area of each rectangle and add them all we will get the surface area automatically.

Now add them all = 70+35+120+35+50 = 310 square inches.

Answer:

slope = - [tex]\frac{4}{3}[/tex] , point on line = (4, - 3 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

y + 3 = - [tex]\frac{4}{3}[/tex] (x - 4) ← is in point- slope form

with slope m = - [tex]\frac{4}{3}[/tex] and point on line (a, b ) = (4, - 3 )

Hi!

The answer to the question: x+3^(3)=(6)/(25)

is x=-669/25

Work:

1)x+3^(3)=(6)/(25)

2)x+27=(6)/(25)

3)x=-669/25

Step 1: Write down the equation

Step 2: Solve the cube root of 3

Step 3: Subtract 27 from both sides.

I hope this helps have an amazing day/night!

God bless!

Answer:

-18x²+3x+1

Step-by-step explanation:

To do this, we need to multiply 6x+1 by 1 and then 6x+1 by -3x:

(6x+1)(1)+(6x+1)(-3x)

Let's first do...

(6x+1)(1)

Distribute 1 to both of the terms inside of the parentheses:

6x(1)+1(1)

6x+1

Then...

(6x+1)(-3x)

Distribute the -3x to both of the terms inside of the parentheses:

6x(-3x)+1(-3x)

-18x²-3x

Then we add them together:

-18x²-3x+6x+1

-18x²+3x+1

Answer:

y = 1/4x - 1 1/2

Step-by-step explanation:

(-6, -3) (2,-1)

y = -3 - (-1) = -2 = 1

x = -6 - 2   = -8 = 4

y = mx + b

-1 = 1/4(2) + b

-1 = 1/2 + b

-1/2 -1/2

-1 1/2 = b

y = 1/4x - 1 1/2

The final equation is y equals one fourth x minus one and one half.

This has to be true because this triangle is classified as an equilateral triangle, which is a triangle.

Hence, Option A, C, and D are correct.

Answer:

A. 5 B. 3,5

Step-by-step explanation:

A. (h/g)(4) means h(x)/g(x) where x=4, so you would set up the equation as (x-9)/(x-3)*(x-5), then plug in 4 for all your x values.

Doing this you get (4-9)/(4-3)*(4-5), simplifying this you get -5/(1*(-1)=5

B. 3 and 5 are the values not in the domain because when you plug them in for you x values you would get a 0 in the denominator.

For example, when you plug in 3 for x, you get -6/(0*-2)=-6/0

This gives you a 0 in the denominator which you can not do
