what amount will be in the fund immediately after the last deposit?(full problem screen shot attached) .

The given expression is expressed in the form of 2(x + p)² + q as:

f(x) = (x + 5)² - 21.5

Given,

Express

2x² + 20x + 7

Step 1: Subtract both sides by 7

2x² + 20x = -7

Step: GCF and divide

2(x² + 10x) = -7

x² + 10x = -7/2

Step 3: Complete the Square

x² + 10x + 25 = -7/2 + 25

(x +5)² = 43/2

Step 4: Subtract 43/2 to both sides

(x + 5)² - 43/2

Hence we get the equation.

The function with same rate of change as the function y = (7/4)x + 3 will be option C.

The rate of change for a function is nothing but rate of change of one thing over the second thing.

it can be calculated by  [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

For a equation written in y = mx + c , m is nothing but the slope / rate of change of function.

So for function  y = (7/4)x + 3

m = 7/4 which is the rate of change for this function.

Now let us find rate of change for each function.

For A rate of change will be = (-4 - 0) / (5 - 1)

= -4/3

For B it will be = ( 4 - 1) / (0 - (-1) )

= 3

For C it will be = (15 - 8) / (8 - 4)

= 7/4

For D it will be = (-2 - 0) / ( 0 - (-1) )

= -2

Therefore the rate of change which is same as the given function is of option C.

The value of x after solution of the equation 8x = -16 is -2 and it is not possible to solve this equation using multiplication.

According to the question,

We have the following equation:

8x = -16

Now, this equation can not be solved using multiplication because 8 is already in multiplication with x on the left hand side. If 8 would have been in division then it could be solved using multiplication.

So, dividing by 8 on both the sides:

x = -16/8

x = -2

Hence, the value of x after solution of the equation 8x = -16 is -2 and it is not possible to solve this equation using multiplication.

As given in the question,

Randi must climb 51 steps from her office to get to the accounting department, and

The HR department is 34 steps below her office.

Since, the HR department is below her office and accountant department is above her office so, we need to add the steps taken from her office to reach both department.

So,

Steps between HR department and accountant department = Steps between her office and HR department + Steps between her office and accountant department

Answer:

8(4-a)=2a

32-8a=2a

32=10a....dividing through by 10a we get..

32/10=10a/10

3.2=a

answer is 3.2

We know that the problem we are going to be dealing with is an equation. The big question is, what should we do? What steps should be taken to get to the answer? There are several steps. One of them is expanding the equation. We can't solve until we expand the left side. So the way we're going to do it is: the distributive property. This one states that if you have an [tex]a[/tex] term multiplied by the sum of  [tex]b[/tex] and [tex]c[/tex] (the last two terms are in parentheses), then, in a sense, [tex]a[/tex] gets "distributed" and what results is this:

[tex]\darkblue{ab+ac}[/tex]. So now we apply that to our problem: [tex]8(4-a)=32-8a[/tex]. Now we make the replacement: [tex]32-8a=2a[/tex]. Then, notice that we have [tex]a[/tex] terms on both sides. What we do is we subtract [tex]2a[/tex] from the right and left and subtract [tex]32[/tex] from the left and add to the right: [tex]-8a-2a=-32[/tex]. Now let me share a little trick with you. First, we can add the [tex]a[/tex] terms together: [tex]-10a=-32[/tex]. Next, if you have minus signs on both sides, you clear them: [tex]10a=32[/tex]. Now divide both sides by 10. Here another trick comes into play: If you divide by 10 you move the decimal sign 1 place to the left.

[tex]a=3.2[/tex]

Now for the checking - put [tex]3.2[/tex] for [tex]a[/tex] and simplify. The answer should be a statement true for all values of [tex]a[/tex]. Let's go.

[tex]8(4-3.2)=2(3.2)[/tex]

[tex]8(0.8)=6.4[/tex]

[tex]6.4=6.4[/tex] is the result. Since the statement is true, we understand that the solution WAS correct and that [tex]3.2[/tex] IS the value of [tex]a[/tex] in the equation [tex]8(4-a)=2a[/tex].

Answer:

  10.4 years

Step-by-step explanation:

Given the population of a small town is initially 13000 and decreasing at the rate of 4% per year, you want to know the number of years it will take for the population to reach 8500.

The equation for exponential decay is ...

  population = (initial population) · (1 - decay rate)^t

Here, the initial population is 13000, the decay rate is 4%, and the population of interest is 8500. This gives an equation we can solve for t.

  8500 = 13000 · (1 -0.04)^t

  8500/13000 = 0.96^t . . . . . . . divide by 13000

  log(17/26) = t·log(0.96) . . . . . take logs

  t = log(17/26)/log(0.96) ≈ 10.408

It will take about 10.4 years for the population to reach 8500 people.

 4 years is the total years will take to reach 8500 people.

 Hence, The total is equal to 4 years.

If a quantity is subject to exponential decay, it is declining at a rate proportionate to its current value.

Given the population of a small town is initially 13000 and decreasing at the rate of 4% per year, you want to know the number of years it will take for the population to reach 8500.

Exponential decay

The equation for exponential decay is ...

 population = (initial population) · (1 - decay rate)^t

Application

Here, the initial population is equal to 13000, the decay rate is equal to 4%, and the population of interest is 8500. This gives an equation we can solve for t.

 8500 =  13000 · (1 -0.04)^t

 8500/13000 = 0.96^t . . . . . . .

divide it by 13000

 log(17/26) = t·log(0.96) . . . . .

 take log

 t = log(17/26)/log(0.96) ≈ 10.408

 It will take about 10.4 years for the population to reach 8500 people.

The maximum height of the object is 88 feet and the time is 2.25 second(s) after launch

The function is given as

h(t) = -16t² + 72t + 7

Differentiate the above function

So, we have the following representation

h'(t) = -32t + 72

Set to 0

-32t + 72 = 0

So, we have

32t = 72

Divide by 32

t = 2.25

Hence, the time is 2.25 seconds

In (a), we have

t = 2.25

Substitute t = 2.25 in h(t) = -16t² + 72t + 7

h(2.25) = -16(2.25)² + 72(2.25) + 7

Evaluate

h(2.25) = 88

for mechanic G since he charges 30 dollars per hour, for x hours his charge will be 30x

so that y = 30x

For K since he charges at rate of 20 dollars per hour, his charge after x hours will be 20x. if he takes 30 dollars reservation fee

The value of x is 10, in the diagram, Vertically opposed angles

What is Vertically opposed angles?

Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.

Here in the diagram 5x = 2y

y = 5X/2

We have 2y+2y+8x = 180 in a straight line.

So 4y+8x = 180

4(5x/2) +8x = 180

10x+8x = 180

x = 180/18

x = 10

Answer:

The 95% confidence interval for the mean tuition for all colleges and universities in the United States is between $15718 and $22882.

Step-by-step explanation:

Sample size greater than 30, which means that we use the normal distribution to find the interval.

We have that to find our  level, that is the subtraction of 1 by the confidence interval divided by 2. So:

α = (1 - 0.95) / 2

  = 0.025

Now, we have to find z in the table as such z has a pvalue of . So it is z with a pvalue of 1 - 0.025 = 0.975.

So, z = 1.96

Now, find M as such

M = z * (σ / √n )

In which σ is the standard deviation of the population and n is the size of the sample.

M = 1.96 * ( 10800 / √35 )

M = 3581.72

M ≈ 3582

The lower end of the interval is the sample mean subtracted by M. So it is 19300 - 3582  = $15718.

The upper end of the interval is the sample mean added to M. So it is  19300 + 3582  = $22882.
