Answer:

y = -20x + 100

Step-by-step explanation:

As per your requirement For Part B, the solution is

The equation in slope-intercept form to model the relations is below:-

To reach 2 points on the graph the line passes through

lets use p1(0, 100), p2(1, 80)

now we will compute the slope:

[tex]m = \frac{(y2 - y1)}{(x2 - x1)}[/tex]

[tex]m = \frac{(80 - 100)}{(1 - 0)}[/tex]

= -20

and now use line equation in form point-slope:

y - y1 = m(x - x1)

y - 100 = -20(x - 0)

y = -20x + 100

Answer:

Part A: 

initial value = 100 (total amount of songs to download)

rate of change = -20 songs/week (100-80 and so on)

Part B: 

ANSWER: y = -20x + 100

y = mx + b, where m is the slope and b is the y-intercept (or initial value).

Answer:

3x - y = - 7

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b) = (- 2, 1) , thus

y - 1 = 3(x + 2) ← distribute

y - 1 = 3x + 6 ( subtract 6 from both sides )

y  - 7 = 3x ( subtract y from both sides )

- 7 = 3x - y, that is

3x - y = - 7 ← in standard form

Answer:

13

Step-by-step explanation:

We have:

8a^2 + 2b^2 = 10

Dividing both sides by 2,

=> 4a^2 + b^2 = 5

or (2a)^2 + b^2 = 5

We also have ab = 2

=> (2a + b)^2

= (2a)^2 + 2(2a)(b) + b^2

= (2a)^2 + b^2 + 4ab

= 5 + 4(2)

= 5 + 8

= 13

Answer:

[tex]Result = 96.24\ km[/tex]

Step-by-step explanation:

Given

92.6 % of 103.93 km

Required

Solve (to 2 decimal places)

To solve this, we simply multiply both 92.6% and 103.93 km together;

[tex]Result = 92.6\% * 103.93\ km[/tex]

Convert percentage to fraction

[tex]Result = \frac{92.6}{100} * 103.93\ km[/tex]

Combine to form a single fraction

[tex]Result = \frac{92.6 * 103.93\ km}{100}[/tex]

[tex]Result = \frac{9623.918\ km}{100}[/tex]

[tex]Result = 96.23918\ km[/tex]

[tex]Result = 96.24\ km[/tex] (Approximated to 2 decimal places)

Clear the brackets

[tex]16x^4 +24x^3+16x^2 -8x^3-12x^2-8x-16x^2-24x-16[/tex]

Now, collect like terms

Answer: Choice B) The conjecture is valid given the focus is on proportional equivalence of two sectors.

This is another way of saying "the two pie slices are the same percentage in area". By this, I mean the percentage of the entire cake. For instance, the shaded slice could be 20% of the entire circle area, for each circle.

It's probably easier to see this is the angle was 90 degrees (split the cake into 4 equal slices, only shade one slice). Or probably even easier if you cut the cake into two slices and only shade one slice (to form a central angle of 180 degrees). For the first example, the slice would be 25% of the whole area, while the second slice is 50%.

Choice C is close, but the two sectors are not the same area. This is because the bottom circle has a larger radius, and therefore its sector area is larger.

Answer:

The equation in slope-intercept form is y = x + 6

Step-by-step explanation:

For this question, we will use point slope form, where you can put in a point and a slope and get an equation of the line that passes through the point with that slope.

The point slope formula is y - y1 = m(x-x1) where y1 is the y coordinate of the point, m is the slope, and x1 is the x coordinate.

We are trying to find a line parallel to x - y = 6, so our line will have the same slope as it. To find the slope of x - y = 6, subtract x and divide by -1. This gives us y = x - 6, where the slope is 1.

Now we have all necessary information.

Plug in the values: y - 5 = 1(x + 1)

Simplify: y - 5 = x + 1

Add 5 to both sides: y = x + 6

The answer is y = x + 6

Step-by-step explanation:

I plugged each equation into a graphing calculator.

Answer:

Our expressions is f(x) = 3|x-7|-7

Let's calculate the limits in +∞ and -∞

So the right staement is B

As x approaches positive infinity, f(x) approaches negative infinity.

A relation is a function if it has only One y-value for each x-value.

The function f(x) = 3|x − 7| − 7 is a piecewise function, where the absolute value function has two cases depending on the sign of (x - 7).

When (x - 7) is positive, the function becomes 3(x - 7) - 7 = 3x - 28, and when (x - 7) is negative, the function becomes -3(x - 7) - 7 = -3x + 14.

As x approaches positive infinity, both cases approach negative infinity because the dominant term in each case is the linear term (3x or -3x) as x becomes large.

Therefore, the end behavior of the function is that as x approaches positive infinity, f(x) approaches negative infinity.

if it was b^4 x b^3 then false. but here, would would multiply b^4 by b^3 to make it 12 so true

sorry for bad explanation

Answer:

True

Step-by-step explanation:

If b=2, 2^4 is 16, and 16^3 is 4096.

Also 2^12 is 4096.

So they are equivalent.

Answer:

a = 1, b = 6

Step-by-step explanation:

The equation given is as follows;

P(x) = a·x³ + b·x² + 3·x - 10

The above equation has a factor of x + 5, therefore, we have;

P(-5) = 0 = a·(-5)³ + b·(-5)² + 3·(-5) - 10

-125·a + 25·b + (-15) - 10 = 0

-125·a + 25·b - 25 = 0

-125·a + 25·b  = 25...........(1)

Also, we are given that;

a·x³ + b·x² + 3·x - 10 divided by x + 1 as a remainder, R = -8, therefore;

P(-1) = -8 = a·(-1)³ + b·(-1)² + 3·(-1) - 10

-a + b - 13 = -8

-a + b = -8 + 13 = 5

-a + b = 5............................(2)

Multiply equation (2) by 25 and subtract from (1) gives

-125·a + 25·b - 25(-a + b) = 25 - 25×5

-100·a = 25 - 125 = -100

a = 1

Therefore, from equation (2) we have;

-1 + b = 5

b = 5 + 1 = 6.

Check out the diagram below. I've marked the angles and sides that are congruent. Notice how the marked sides are not between the marked angles for either triangle. So we're dealing with AAS instead of ASA. The order is important. If we wanted to use ASA, then we would have to know DE = TU, both of those sides are between the marked angles.

This question was on my online school assignment. I can go back on my assignments and review and I had got it right.

Answer:

We have 13 different beads to use in our necklace, and the thing that will make a necklace different to others, is the position of the beads.

And because we can not turn the necklaces over, the mirrored necklaces are different (the positions of the beads are mirrored)

For the first bead, we have 13 options, for the second, 12 options, and so on

the total number of combinations is equal to the product of the options for each selection, then we have:

C = 13*12*11*10*9*8*7*6*5*4*3*2*1 combinations:

C = 6,227,020,800.

Now, we are allowed to rotate the necklace, this means that a combination.

a b c d e f g h i j k l m (each letter is equivalent to one of the different beads)

is the same as other ordered as

m a b c d e f g h i j k l

And for each combination, we have 13 rotations, then the actual number of combinations is:

C/13 = 6,227,020,800/13 = 479,001,600

Using arrangements, it is found that 6,227,020,800 different necklaces can be made using 13 different beads.

The beads can be exchanged among the positions to form the necklace, hence, the arrangements formula is used.

This formula gives the number of possible arrangements of n elements, and is defined by:

[tex]A_n = n![/tex]

In this problem, the necklaces are formed by 13 beads, hence [tex]n = 13[/tex] and:

[tex]A_{13} = 13! = 6227020800[/tex]

6,227,020,800 different necklaces can be made using 13 different beads.

Step-by-step explanation:

Let us use the scale 1 : 75 to find the length of the gym on the scale drawing.

The scale means that 1 m on the drawing represents 75 m in real life.

Therefore, if the length of the gym is 12.3 cm, then the length of the gym in the scale drawing is:

12.3 / 75 = 0.164 m

Converting to cm:

1 m = 100 cm

0.164 m = 0.164 * 100 = 16.4 cm
