Answer:

130.3 ft²

Step-by-step explanation:

Surface area is the sum of areas of outer faces

2 rectangles + 2 triangles + curved surface area of the cylinder

2(4×6) + 2(½×6×5) + 2×3.14×(2/2)×4

48 + 30 + 25.12

103.12 ft²

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

[tex]P=500,000[/tex]

It contains 6 zeroes. It means,

[tex]P=5\times 10^6[/tex]

So, the order of magnitude for the number of people in Portland is 6.

[tex] \frac{3 \sqrt{5} }{ \sqrt{15} } = 3 \times \sqrt{ \frac{5}{15} } = \frac{3}{ \sqrt{3} } \\ [/tex]

Answer:

20/81.

Step-by-step explanation:

There are 5 odd numbers in 1 to 9 and 4 even ones.

Prob(Odd number on first spin) = 5/9

Prob(Not flipping heads on second) = 1/2

Prob(Not spinning a 6 on third ) =  8/9

The compound probability is found by multiplying the above ( because each trial is independent of the others):

Answer = 5/9 * 1/2 * 8/9

= 40/162

= 20/81.

Answer:

P(sum is even) = 1/16 + 9/16 = 10/16

= 5/8

P(sum is odd) = 3/8

E(x) = (5/8)(6) + (3/8)(-2) = 3

The mathematical expectation for the number of spaces moved in one turn is 3 spaces forward.

The average rate of change for a square root function decreases as we look at intervals of fixed lengths over the domain and the endpoints of those intervals increase. This is due to the property of the square root function where it's an increasing function but at a decreasing rate.

The average rate of change of a function measures how the output (y-value) changes in comparison to the input (x-value). For a square root function like f(x) = √x, as we look at intervals of fixed lengths over the domain and as the endpoints of those intervals increase, the average rate of change decreases.

This happens because the slope of the tangent line to the function (which represents the rate of change) gets progressively less steep as x increases. Square root functions are increasing functions but at a decreasing rate. For example, the slope between the points (1,1) and (4,2) on the function f(x) = √x is 1/3, but between (4,2) and (9,3), it's 1/5, indicating a decrease in the rate of change.

Answer:

x = 39

Step-by-step explanation:

To solve for x, we have to get it by itself in the equation.

In this problem, we have to do the opposite of subtraction and add 36 to the left and right side of the equation.

3 + 36 = x - 36 + 36

36 + 3 is equal to 39 and -36 + 36 cancels out.

This leaves us with 39 = x.

Answer:  f(x) = (x + 3)(x – 7)

Step-by-step explanation:  Use "standard form" of the function and insert values given: vertex (2,-25) intercept point (7,0)

f(x) = a(x-h)² + k   from vertex, h is 2   y is -25   from intercept,  x is 7  f(x) is 0

to find a,  0 = a(7-2)² +(-25)   0 = a(7-2)² -25  add 25 to both sides

25 = a(5)²  25 = 25a  25/25 = a  1=a  (seems useless but verifies implied "a"coefficient is 1)

f(x) = a(x-h)² + k solve to get the quadratic form

f(x) = (x-2)² -25     (x - 2)² is x² -4x +4

f(x) = x² -4x +4 -25  simplify

f(x) = x² -4x - 21   then factor

f(x) = (x + 3)(x - 7)

Answer:

f(x) = (x + 3)(x - 7)

Answer:

Convert   4.5% to a decimal. 6000,0.045, 8 years

Step-by-step explanation:

I used math--way

The value of the account after 8 years with continuous compounding is approximately $8593.76.

To find the value of the account after 8 years with continuous compounding, we can use the formula for continuous compounding:

A=P⋅e rt

Where:

A is the amount of money accumulated after

t years, including interest.

P is the principal amount (the initial amount of money).

r is the annual interest rate (in decimal).

t is the time the money is invested for, in years.

e is the base of the natural logarithm, approximately equal to 2.71828.

Given:

P=$6000

r=4.5%=0.045 (in decimal)

t=8 years

Substituting the values into the formula:

A=6000⋅e 0.045⋅8

Now, let's calculate this:

A=6000⋅e 0.36

A≈6000⋅2.71828 0.36

A≈6000⋅1.432292989

A≈8593.757934

Rounding to two decimal places, the value of the account after 8 years with continuous compounding is approximately $8593.76, which is slightly different from the provided answer of $8532.60. This discrepancy might be due to rounding differences or calculation variations.

Answer:

3.6 cm

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2)*h

We know the area of 4.5  and the top is 1 and the bottom is 1.5

4.5 = 1/2 (1+1.5) h

4.5 = 1/2 (2.5) h

4.5 =1.25h

Divide each side by 1.25

4.5/1.25 = 1.25h/1.25

3.6 =h

Answer:

[tex]3.6 \: \: cm[/tex]

Step-by-step explanation:

[tex]area \\ 4.5 = \frac{1}{2}(a + b ) \times h \\ 4.5 = \frac{1}{2} (1 + 1.5) \times h \\ 4.5 = \frac{1}{2} \times 2.5 \times h \\ 4.5 = \frac{2.5h}{2} \\ 4.5 = 1.25h \\ \frac{4.5}{1.25} = \frac{1.25h}{1.25} \\ h = 3.6 \: cm[/tex]
