Ricks sporting good:

100% - 20% = 80% so the basketball is on sale for 80% of the original price so 24.95 x 0.80 = 19.96 ( sale price)

Sports Expert:
100% - 25% = 75%
so the basketball is on sale for 75% of the original price 25.80 x 0.75 = 19.35 (sale price)

19.35 is less than 19.96 so the better deal is from Sports Expert

A company is producing a new product. Due to the nature of the product, the time required to produce each unit decreases as wor

balu736 [363]

Answer:

The total time to produce units 1 through 10 = 21.762 hours

The total time to produce units 30 through 40 = 22.187 hours

Step-by-step explanation:

Function for the learning process is T(x) = 2 + 0.6(1/x)

Time required to produce 1st unit = 2.6

Time required to produce 2nd unit = 2.3

Time required to produce 3rd unit = 2.2

Time required to produce 4th unit = 2.15

Time required to produce 5th unit = 2.12

Time required to produce 6th unit = 2.1

Time required to produce 7th unit = 2.09

Time required to produce 8th unit = 2.075

Time required to produce 9th unit = 2. 067

Time required to produce 10th unit = 2. 06

The total time required for a new worker to produce units 1 through 10 is the sum of the above times. The total time to produce units 1 through 10 = 21.762

Function for the learning process is T(x) = 2 + 0.6(1/x)

Time required to produce 30th unit = 2.02

Time required to produce 31st unit = 2.019

Time required to produce 32nd unit = 2.0188

Time required to produce 33rd unit = 2.018

Time required to produce 34th unit = 2.0176

Time required to produce 35th unit = 2.017

Time required to produce 36th unit = 2.0167

Time required to produce 37th unit = 2.016

Time required to produce 38th unit = 2.0158

Time required to produce 39th unit = 2. 0154

Time required to produce 40th unit = 2. 015

The total time required for a new worker to produce units 30 through 40 is the sum of the above times. The total time to produce units 30 through 40 = 22.187

Use the method of disk or washer to set up, but do not evaluate, an integral for a volume of the solid obtained by rotating the

Sedbober [7]

Answer:

V = π /2 volume units

Step-by-step explanation:

Volume of y = √x bounded by y = x and y = 1

y = √x

limits of integration ( see Annex )

By simple inspection limits of integration are x = 0 to x = 1

or y = √x and y = x

solving these two equations

x = 0 y = 0 x = 1 y = ± 1

V = ∫ π*f(x)²*dx

V = π * ∫₀¹ x*dx = π * x²/2 |₀¹

V = π * (1/2) - 0

V = π /2 volume units

What is matrix X if 0.5X=A? Matrix A=[6 -12 4 6].

vladimir1956 [14]

Answer:

See attachment

Step-by-step explanation:

The given matrix equation is:

$0.5X = A.$

To find Matrix X, we need to multiply both sides of the equation by 2 to obtain:

$2 \times 0.5X =2 \times A$

This simplifies to;

$X = 2A$

By scalar multiplication, we multiply each entry in the matrix A by to 2 to obtain matrix X.
