Answer:

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Let's check if the triangle with sides of 30, 64, and 90 is a right triangle:

30^2 + 64^2 = 900 + 4096 = 4996

90^2 = 8100

Since 4996 is less than 8100, the triangle is not a right triangle.

In an acute triangle, all angles are less than 90 degrees. In an obtuse triangle, one angle is greater than 90 degrees.

To determine if the triangle is acute or obtuse, we need to find the largest side. The largest side is 90. Let's find the sum of the squares of the other two sides:

30^2 + 64^2 = 900 + 4096 = 4996

Since 4996 is less than 90^2, the triangle is acute.

Therefore, the triangle with sides of 30, 64, and 90 is an acute triangle.

the triangle is obtuse

Step-by-step explanation:

[tex] {90}^{2} = 8100[/tex]

[tex] {30}^{2} + {64}^{2} = 4996[/tex]

[tex] {30}^{2} + {60}^{2} < {90}^{2} [/tex]

triangle is obtuse because the square of the largest is greater than the sum of the square of the other 2 sides

Answer:

-91

Step-by-step explanation:

To find the partial sum for the sequence

[tex]\large \boxed{\mathrm{ \ 0, \ -1, \ -3, \ -6, \ -10,}}[/tex]

We first notice that the first term is

[tex]\large \boxed{\mathrm{0}}[/tex],

And each subsequent term is the sum of the previous term and the next integer in the sequence starting with [tex]-1.[/tex] Therefore, we can use the formula for the sum of an arithmetic series to find the partial sum S14:

S14 = 14/2 * (2(0) + (14-1)(-1+0)/2) = 14/2 * (13/2 * -1) = -91

Therefore, the partial sum for the sequence up to the [tex]14th[/tex] term is [tex]-91.[/tex]

Answer:

[tex]91[/tex]

Step-by-step explanation:

The partial sum of a sequence is the sum of a certain number of terms in the sequence. For the given sequence

{0, −1, −3, −6, −10, ...},

The nth term can be represented as Tn = n(n-1)/2. This means that the partial sum of the first 14 terms of the sequence, denoted by S14, can be calculated by adding up the first 14 terms using the formula: S14 = 0 + (-1) + (-3) + (-6) + (-10) + ... + T14.

Simplifying this expression using the formula for Tn, We get S14 = 91. Therefore, the partial sum for the given sequence up to the 14th term is equal to 91.

Answer:

The tip of the minute hand on a clock travels 15π inches in 45 minutes if the distance from the center to the tip is 10 inches.

Answer:

a. $1,240

b. $1,960

c. 9 years

d. 17 years

Step-by-step explanation:

For interest you multiply the percent with 1,000 and add the number you get for your answer. So 1,000 times 6% is 60. Each year the account earns $60 worth of interest. You multiply 60 by 4 and your result is 240. You add 240 to 1,000 and get your answer for a $1,240.

You repeat the same process for b. 16 times 60 is 960. You add 960 and 1,000 and your answer is $1,960.

So we know the account already has $1,000 so all that has to be done is to divide 500 by 60 and your result is 8.3. However you it is anual interest so you cannot but in a decimal so you round up to 9. Making it 9 years

Same process dividing 1,000 by 60 which gives you 16.6 rounding up to 17. Making it 17 years.

Let x be the length of the shortest side. Then, the length of the second side is 2x, and the length of the third side is x + y, where y is the additional length.

The perimeter of the triangle is the sum of the three sides, so we have:

x + 2x + (x + y) = 60

Simplifying this equation, we get:

4x + y = 60

We also know that the area of a triangle is given by:

A = (1/2)bh

where b is the length of the base, and h is the height. Since the base of the flower bed is the shortest side of length x, we can choose the height to be y. Therefore, we have:

A = (1/2)xy

Now we need to solve for x and y. We can use the equation for the perimeter to solve for y:

y = 60 - 4x

Substituting this into the equation for the area, we have:

A = (1/2)x(60 - 4x)

Simplifying and expanding, we get:

A = 30x - 2x^2

To maximize the area, we can take the derivative of A with respect to x and set it equal to 0:

dA/dx = 30 - 4x = 0

Solving for x, we get:

x = 7.5

Substituting this back into the equation for y, we get:

y = 60 - 4x = 45

Therefore, the dimensions of the flower bed are:

shortest side = x = 7.5 feet second side = 2x = 15 feet third side = x + y = 52.5 feet

The second job offer is better by $21,840.

We have :

An employee is considering two job offers.

First offer: $57,000 yearly salary with an 8% matching 401k

Second offer: $63,000 yearly salary with a 4% matching 401k

Let's calculate the total value of the second offer after 4 years:

Yearly salary is : $63,000

Total gross income after 4 years: $63,000 x 4 = $252,000

The company matches 5% of the employee's salary.

So, the employee contributes 5% of $63,000 = $3,150 per year

After 4 years,

Company matches: $3,150 x 4 = $12,600

Employee contributions: $3,150 x 4 = $12,600

Total 401k contributions: $12,600 + $12,600 = $25,200

The total value of the second offer after 4 years is:

Total value: $252,000 + $25,200 = $277,200

Now, let's compare this to the total value of the first offer, which is : $255,360.

Therefore, the second job offer is better by:

$277,200 - $255,360 = $21,840

The functions g(x) = -√x - 3 and h(x) = x + 4 meet the requirements, and f(x) = g(h(x)) is true for f(x) = -√(x+4) - 3.

We are given f(x) and we need to find functions g(x) and h(x) such that f(x) = g(h(x)). The given function is f(x) = -√(x+4) - 3.

To find g(x) and h(x), we can split the given function into two simpler functions. Let's first look at the inner function, which deals with the input of the square root. We can define h(x) as the function inside the square root, which is:

h(x) = x + 4

Now we need to find g(x) such that when h(x) is plugged into it, we get the original function f(x). Since we have the square root and a subtraction, we can define g(x) as:

g(x) = -√x - 3

Now let's verify if f(x) = g(h(x)):

g(h(x)) = g(x + 4) = -√(x + 4) - 3

As you can see, g(h(x)) = f(x), which confirms that the functions g(x) and h(x) we found satisfy the condition.

Answer:

Each small box has 24/17 beads.

Step-by-step explanation:

Let's call the number of beads in each small box "s" and the number of beads in each large box "l".

We know that there are 14 small boxes, so the total number of beads in the small boxes is 14s. We also know that there are 3 large boxes, so the total number of beads in the large boxes is 3l.

From the problem, we know that there are 4 more beads in each large box than in each small box, so we can write:

l = s + 4

We also know that 7/9 of the total number of beads were packed in the small boxes, so we can write:

14s + 3l = 7/9(total number of beads)

We can simplify this expression by substituting l = s + 4:

14s + 3(s + 4) = 7/9(total number of beads)

Expanding and simplifying:

17s + 12 = 7/9(total number of beads)

Now, we need one more equation to solve for s. We know that the total number of beads is equal to the sum of the beads in the small and large boxes:

total number of beads = 14s + 3(s + 4)

Simplifying:

total number of beads = 17s + 12

Now we have two equations that we can use to solve for s:

17s + 12 = 7/9(total number of beads)

total number of beads = 17s + 12

We don't know the total number of beads, but we do know that it is a multiple of both 14 and 3 (since there are 14 small boxes and 3 large boxes). The smallest multiple of both 14 and 3 is 42, so let's assume that the total number of beads is 42x, where x is some number.

Substituting 42x for "total number of beads" in the two equations:

17s + 12 = 7/9(42x)

42x = 17s + 12

Simplifying:

153s + 108 = 98x

42x = 17s + 12

Now we have two equations and two unknowns (s and x). We can solve for s in terms of x by isolating s in the second equation:

17s = 42x - 12

s = (42x - 12)/17

We can substitute this expression for s into the first equation:

17((42x - 12)/17) + 12 = 7/9(42x)

Simplifying:

42x - 12 + 12 = 14x

28x = 24

x = 24/28 = 0.857

Now we know that the total number of beads is:

42x = 42(0.857) = 36

And we know that each small box has:

s = (42x - 12)/17 = (36 - 12)/17 = 24/17

So each small box has 24/17 beads.
