Evaluate the expression when c = 4, d = 1 and e = 10. d+18

A computer is used to generate passwords. Passwords are made up of numbers from 1–8 and lowercase letters.

Fynjy0 [20]

Answer:

.76

Step-by-step explanation:

there are 26 letters. the 26 letters and 8 numbers make up the pool of 34 numbers to choose from, each with 1/34 chance of being picked. the 26 letters combined thus have a combined probobility of 26/34 or 13/17. in decimal,.764...

Pleasr help me ASAP! Thank you^-^ If w = 10 units, x = 5 units, and y = 6 units, what is the surface area of the figure? Round y

Sladkaya [172]

Answer:

D:456.2 units²

Step-by-step explanation:

Step 1: Area of all 4 sides of cuboid

Area of rectangle = 4 x length x breadth

Area of rectangle = 4 x 10 x 5

Area of rectangle = 200

Step 2: Calculate bottom of cuboid

Area = length x breadth

Area = 10 x 10

Area = 100

Step 3: Calculate slant height of pyramid

c² = a² + b²

c² is hypotenuse

a² is the base which is half of w (10/2 = 5)

b² is y which is 6

c² = a² + b²

c² = 5² + 6²

c = √61

Step 4: Calculate area of one face of the pyramid

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 10 x √61

Area of triangle = 5√61

Step 5: Calculate areas of all 4 faces of the pyramid

4 x 5√61 = 20√61

Step 6: Calculate the total surface area

Total surface area = 200 + 100 + 20√61

Total surface area = 456.2

The surface area of the figure is 456.2 units²

Option D is correct.

Describe how the graph of y = |x - 2| - 5 is a transformation of the graph of y = |x|. Use terms such as "shifted", "reflected",

valentinak56 [21]

Answer:

The original graph was shifted 2 units to the left and 5 units down.

Step-by-step explanation:

y = |x|

From this, we go to: y = |x - 2|.

When we want to shift a function f(x) a units to the left, we find f(x - a). So first, the graph was shifted 2 units to the left.

y = |x - 2|.

From this, we go to: y = |x - 2| - 5.

Shifting a function f(x) down b units is the same as finding f(x) - b, so the second transformation was shifting the graph 5 units down.

Marco wants to invest his savings in a bank for 3 years. He has borrowed £15,0000 to invest and receives offers from two banks.

azamat

Answer:

Marcos Should invest with the first bank

Step-by-step explanation:

Formula for finding compound interest is: A = p(1+\frac{r}{n})^{nt}

where

A = the future value of the investment

P = the principal investment amount (the initial deposit)

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested

If marcos choose to invest with the first bank

A = 15000(1+\frac{0.025}{12})^{12*3} = £16166.81

If he choose to invest with the second bank

His principal become 15570 in the first year because of the 3.8% offer from the bank and t becomes 2.

A = 15570(1+\frac{0.01}{12})^{12*2} = £15884.27

Comparing the future value of his investment from both bank, Marcos will get more interest from investing with the first bank.

Solve for x. x+139 132°

arsen [322]

Answer:

as we know that corresponding angles are same if two parallel line cut by Traversal opposite angle are also same

means x+139=132

so x=132-139

then x=-7
