Answer:

-26042

Step-by-step explanation:

sum of a finite geometric series =

[tex]\frac{a_1(1-r^n)}{1-r}[/tex]

here, a1 is the first term, r is the common ratio, and n is the number of terms

a1 = -2

r = -5

n = 7

[tex]\frac{a_1(1-r^n)}{1-r} = \frac{-2(1-(-5)^7)}{1-(-5)} = -26042[/tex]

Answer:

The range of an exponential function, or any function is all the possible y values the function can spit out.

In MOST exponential functions they will be x>0

I am talking about the standard form: y = a * b^x

I cannot tell you the range for YOUR exponential function without seeing it first.

Answer: r = 5

Steps:

[tex]a_n=ar^{n-1}[/tex]

1. add Values to formula

2. get r alone

[tex]\frac{1250}{2}=\frac{2r^{4}}{2}[/tex]  ➜ [tex]625= r^4[/tex]
3. get rid of the exponents

Answer:

4x-5

Step-by-step explanation:

A set of n elements has 2ⁿ subsets. One of these subsets is the set itself, so this set would have 2ⁿ - 1 proper subsets.

The given set has 4 elements, so it has 2⁴ = 16 subsets and 2⁴ - 1 = 15 proper subsets.

Just to illustrate the claim, we have

• subsets of size 0 (1 of these):

{ } (empty set)

• subsets of size 1 (4 of these):

{1/6}, {1/7}, {1/8}, {1/9}

• subsets of size 2 (6 of these):

{1/6, 1/7}, {1/6, 1/8}, {1/6, 1/9}, {1/7, 1/8}, {1/7, 1/9}, {1/8, 1/9}

• subsets of size 3 (4 of these):

{1/6, 1/7, 1/8}, {1/6, 1/7, 1/9}, {1/6, 1/8, 1/9}, {1/7, 1/8, 1/9}

• subsets of size 4 (1 of these):

{1/6, 1/7, 1/8, 1/9}

and the last one is the only subset that is not a proper subset, because that subset = the set.

The number of subsets are 16 and number of  proper subsets for the set are 15. So, correct option is A.

The set {1/6, 1/7, 1/8, 1/9} has 4 elements.

To calculate the number of subsets, including both the proper and improper subsets, you can use the formula 2ⁿ, where n is the number of elements in the set.

So, for this set, there are 2⁴ = 16 subsets.

To calculate the number of proper subsets, you subtract 1 from the total number of subsets (to exclude the empty set).

So, the number of proper subsets is 16 - 1 = 15.

Hence, option A is correct, the number of subsets are 16 and number of  proper subsets for the set are 15.

To describe the transformation of the parent logarithmic function, you just need to follow these rules

1. A +  on the outside of the parentheses will mean a vertical shift upwards. As such, the transformation is moved 5 units up. If it was -, it would move 5 units down.

2. The inside of the parentheses will result in a horizontal shift right 4 units. The rule to remember is that these kinds of functions follow x(a - b) rules, meaning that when the 4 is subtracted, we are really talking about a positive four, unlike in standard arithmetic. Vice versa, a + 4 will mean a -4 four, since a - -4 is the same as a + 4. As such, we will move in the positive direction (right) on the y axis.

3. Since x is now -2x, we are reflecting about the y axis, meaning the function will switch from left to right or right to left.

4. The 2 in front of it represents a vertical dilation by a factor of 2. This is because our constant, 2, is greater than 1. If the number were in between 0 and 1, it would represent a vertical compression by the constant number.

The equation that can be used to find the time t, in hours,  it would take Johnson and Nathan to tile a 100 square foot area together is 3.9375 hours, which approximates to 4 hours.

More people to do a task means less time it will take.

Less people to do a task means more time it will take.

Thus, they are inversely related.

If x men take y time for a work,(assume all men have same strength)

We can define a constant as "Manpower" needed for doing that specific work.

Let we define:

Manpower needed for a work = y + y + y + .. + y = Time per man × count of men

Manpower needed for a work = xy

For this case, we're specified that:

So, we see that strength of Johnson and Nathan are different.

Let the general manpower (from some frame of a general public or any third frame) needed by this work be M.

Then, Johnson delivers M manpower in 7 hours or M/7 manpower in one hour.

In the similar way, Nathan delivers M/9 manpower per hour.

Thus, if Nathan and Johnson work together, they can deliver: [tex]\dfrac{M}{9} + \dfrac{M}{7} = M\dfrac{9+7}{63} = \dfrac{16M}{63}[/tex] manpower per hour.

Let it takes them together h hours to complete the work.
That means, in 'h' hours, their together work power will accumulate to M manpower.

Or, we can say:

[tex]h \times \dfrac{16M}{63} = M\\\\h = \dfrac{63M}{16M} = \dfrac{63}{16} = 3.9375[/tex]

Thus, the equation that can be used to find the time t, in hours,  it would take Johnson and Nathan to tile a 100 square foot area together is 3.9375 hours, which approximates to 4 hours.

Answer:

slope = 2, y-intercept = 3

Step-by-step explanation:

» Concepts

All straight lines can follow the slope-intercept form, y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. The slope is the constant rate of change, and the y-intercept is where the line intersects at the y-axis.

» Application

We are asked to find the slope and y-intercept of the equation, y = 2x +3, given the form y = mx + b. As you can see, in the place of m (the slope), there is the number 2, making the slope 2. Then, in the place of b (the y-intercept), there is the number 3, making the y-intercept 3.

Answer:

y = 2x

Step-by-step explanation:

Parallel line share the same slope, therefore we can put any parallel line of y = 2 (x + 1) in equation as: y = 2x + k

As the parallel has to intercept with point (2/3, 1/3), simply put the coordinate into the equation to get value of k

2/3 = 2(1/3) + k

k = 0

Therefore the equation of this parallel line is y = 2x
