Answer:

r = 4/5

Step-by-step explanation:

Formula

Sum of an infinite geometric series = a / (1 - r)

Givens

Sum = 5*a

a = a

r = ?

Solution

5a = a/(1 - r)                   Divide both sides by a

5a/a = a / (a * (1 - r)       The a's on the right cancel

5 = 1 / (1 - r)                    Multiply both sides by 1 - r

5*(1 - r) = 1*(1 - r)/(1 - r)   The 1 - r s on the right cancel

5*(1 - r) = 1                     Remove the brackets.

5 - 5r = 1                        Subtract 5 from both sides

5-5 - 5r = 1 - 5               Combine

-5r = - 4                          Divide by - 5

r = 4/5  

Answer:

1.667

Step-by-step explanation. Step by Step SolutionRearrange:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :                      5/w-(3)=0 Step by step solution :STEP 1: 5

Simplify —

w

Equation at the end of step 1: 5

— - 3 = 0

w

STEP 2:Rewriting the whole as an Equivalent Fraction  2.1   Subtracting a whole from a fraction Rewrite the whole as a fraction using  w  as the denominator : 3 3 • w

3 = — = —————

1 w

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominatorAdding fractions that have a common denominator : 2.2       Adding up the two equivalent fractions Add the two equivalent fractions which now have a common denominatorCombine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible: 5 - (3 • w) 5 - 3w

——————————— = ——————

w w

Equation at the end of step 2: 5 - 3w

—————— = 0

w

STEP 3:When a fraction equals zero : 3.1    When a fraction equals zero ...Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.Here's how: 5-3w

———— • w = 0 • w

w

Now, on the left hand side, the  w  cancels out the denominator, while, on the right hand side, zero times anything is still zero.The equation now takes the shape :   5-3w  = 0Solving a Single Variable Equation: 3.2      Solve  :    -3w+5 = 0  Subtract  5  from both sides of the equation :                       -3w = -5 Multiply both sides of the equation by (-1) :  3w = 5 Divide both sides of the equation by 3:                     w = 5/3 = 1.667 One solution was found : w = 5/3 = 1.667                  

Answer:

The formula for volume of a cone is area of a circle times height, divided by 3.

Therefore volume is pi times radius squared times height, divided by 3.

V = (3.14)(14)^2 (14)/3

V = (3.14) (196)(14)/3

V = (3.14) (2744)/3

V = 8616.16/3

V = 2872.05333

to the nearest hundredth is 2872.05 cubic yards.

Step-by-step explanation:

In the circle the measure of angle QPR in radians is π/4.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

The length of the arc QR is 4π, which is 1/2 of the circumference of the circle P.

Therefore, the circumference of the circle is -

2πr = 2π(8) = 16π

The angle subtended by the arc QR at the center of the circle is therefore -

θ = arc length / radius

θ = (4π) / 8

θ = π/2

Now, consider the triangle QPR.

The angle QPR at the center of the circle is equal to twice the angle subtended by the arc QR at any point on the circumference of the circle.

Therefore -

2∠QPR = θ = π/2

Solving for ∠QPR, we get -

∠QPR = (π/2) / 2

∠QPR = π/4

Therefore, the measure QPR is π/4.

Four times the quotient of 3 divide by 4

We know that we are going to be multiplying 4 by something because in the statement we have four times.  Reading further we also know that we are going to be dividing 4 from 3 which means that we will have 3/4.  Finally, we see that we multiply our 3/4 by 4 which gives us our final solution.

[tex]4 * (3 / 4)[/tex]

If we want to solve it the 4's would just cancel and we would be left with 3.

3

Explanation:

You would start by dividing 3 by 4. Then multiply [tex]\frac{3}{4}[/tex] and 4. The 4s would cancel out leaving you with 3.

[tex]\frac{3}{4}[/tex] × [tex]4=3[/tex]

[tex]f(x) = x^3 -6x^2 -11x +k \\\\\text{If (x +3) is a factor of f(x), then,}~ f(-3) = 0\\\\~~~~~~~f(-3) = 0\\\\\implies(-3)^3-6(-3)^2 -11(-3) +k = 0\\ \\\implies -27-54+33 +k=0\\\\\implies -48+k = 0\\\\\implies k = 48[/tex]
