Answer:

8%

Step-by-step explanation:

4/50 = 0.08, which is 8%

If 500 is not a typo, then 4/500 = 0.008, which would be 0.8%

Answer: 8%

Step-by-step explanation: 4/50 = 0.08 Convert the decimal to a percentage. 0.08 = 8%

Answer:

t = 63.897 years

Step-by-step explanation:

Simple interest rate formula: A = P(1 + r)^t

Simply plug in what we know and solve:

12502 = 1020(1 + 0.04)^t

6251/510 = 1.04^t

log base 1.04 of (6251.510) = 63.897

Sample Response:

No, he is not correct. Jay drew a line through the origin, but the line did not connect all three points. Not all the points lie on the line, which is necessary for a proportional relationship.

alternative response:

No. He is not correct, this graph does not represent a proportional relationship. The graph of a proportional relationship must be a straight line connecting all points and passing through the origin.. as well as not even connecting all three points on the graph.

In a directly proportional relationship, increasing one variable will increase another. It is not a proportional relationship graph.

Let there are two variables p and q

Then, p and q are said to be directly proportional to each other if

 p = kq

where k is some constant number called the constant of proportionality.

This directly proportional relationship between p and q is written as

 p∝q  where that middle sign is the sign of proportionality.

In a directly proportional relationship, increasing one variable will increase another.

Now let m and n be two variables.

Then m and n are said to be inversely proportional to each other if

[tex]m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}[/tex]

(both are equal)

where c is a constant number called the constant of proportionality.

This inversely proportional relationship is denoted by

[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]

As visible, increasing one variable will decrease the other variable if both are inversely proportional.

A proportional relationship is a relationship in which the value of one variable changes with the change in another variable. This change is always in a fixed ratio. Thus, when the relationship is plotted on the graph it creates a straight line and all the data points lie on this line.

Since in the graph made by Jay the line is not able to connect all the data points, it is not a proportional relationship graph.

By the property of a parallelogram,

" Consecutive angles of a parallelogram are supplementary"

In the figure attached,

∠DCB and ∠CDA are the supplementary angles. Therefore ABCD will be a parallelogram.

Answer:

El libro que Renzo está leyendo tiene 300 páginas.

Step-by-step explanation:

Dado que Renzo ha leído el 20 por ciento del libro de cuentos, en principio le queda leer el 80 por ciento de éste. Ahora bien, de las páginas restantes (es decir, de ese 80 por ciento) ha leído 1/4 parte. Por ende, ha leído un 20 por ciento adicional de dicho libro (80 /4 x 1 = 20). En conclusión, Renzo lleva leído un 40 por ciento del libro, con lo cual le resta leer un 60 por ciento, que está formado por 180 páginas. Para determinar cuántas páginas tiene el libro, entonces, hay que realizar el siguiente cálculo:

180 / 60 = 3 (valor del 1 por ciento del libro)

3 x 100 = 300 (valor del 100 por ciento del libro)

Por lo tanto, el libro que Renzo está leyendo posee 300 páginas.

The equivalent factored form of this equation is (x² + 49)(x - 6)

Step-by-step explanation:

x³ - 6x² + 49x - 294

First, group the first and second terms together and group the last two terms together.

(x³ - 6x²) + (49x - 294)

Find the greatest common factor of both parentheses and factor them.  

x²(x - 6) + 49(x - 6)

Now, since the two terms in the parentheses are the same, then we have factored the equation correctly.

So, the factored form of the equation is (x² + 49)(x - 6)

Answer:(x-6)(x+7i)(x-7i)

Step-by-step explanation:

(x-6)(x^2+49)=(x-6)(x^2-(-49)

(x-6)(x^2-(7i)^2)

(x-6)(x+7i)(x-7i)

Answer:

The new line is steeper than the original, but still crossing the y=axis at 7 .

Step-by-step explanation:

Since what has changed from y = 2 x + 7 going into y = 5 x + 7 is the slope of the linear function, (from 2 to 5) what one would notice is that the new line is steeper - raising 5 units every one unit ste to the right- but would still be intersecting the y-axis at the point (0, 7), since the y-intercept has not changed.

Answer:

(2, f(2))

Step-by-step explanation:

f(x) = -3x^2

For point B, the y-coordinate is f(2).

Point B is (2, f(2))

Answer:

The equation of the function in vertex form is f(x) = -2·(x - 8)² + 6

Step-by-step explanation:

The given values are

x,            f(x)

6,             -2

7,              4

8,              6

9,              4

10,            -2

The equation of the function in vertex form is given as follows;

f(x) = a × (x - h)² + k

To find the values of a, h, and k, we proceed as follows;

When x = 6, f(x) = -2

We have;

-2 = a × (6 - h)² + k = (h²-12·h+36)·a + k.............(1)

When x = 7, f(x) = 4

We have;

4 = a × ( 7- h)² + k = (h²-14·h+49)·a + k...........(2)

When x = 8, f(x) = 6...........(3)

We have;

6 = a × ( 8- h)² + k

When x = 9, f(x) = 4.

We have;

4 = a × ( 9- h)² + k ..........(4)

When x = 10, f(x) = -2...........(5)

We have;

-2 = a × ( 10- h)² + k

Subtract equation (1) from (2)

4-2 =  a × ( 7- h)² + k - (a × (6 - h)² + k ) = 13·a - 2·a·h........(6)

Subtract equation (4) from (2)

a × ( 9- h)² + k - a × ( 7- h)² + k

32a -4ah = 0

4h = 32

h = 32/4 = 8

From equation (6) we have;

13·a - 2·a·8 = 6

-3a = 6

a = -2

From equation (1), we have;

-2 = -2 × ( 10- 8)² + k

-2 = -8 + k

k = 6

The equation of the function in vertex form is f(x) = -2·(x - 8)² + 6

Answer:

f(x) = -2(x - 8)² + 6

Explanation:

Triangles HIG and FED are similar triangles. We know this because we have two pairs of angles that are congruent (angle G = angle D; angle I = angle E). Use the AA (angle angle) similarity theorem.

Since angles G and D are congruent, computing sin(D) is equivalent to finding sin(G)

sin(angle) = opposite/hypotenuse

sin(G) = IH/HG

sin(G) = 77/85

sin(D) = 77/85

Answer:

Step-by-step explanation:

Let's call hens h and ducks d. The first algebraic equation says that 6 hens (6h) plus (+) 1 duck (1d) cost (=) 40.

The second algebraic equations says that 4 hens (4h) plus (+) 3 ducks (3d) cost (=) 36.

The system is

6h + 1d = 40

4h + 3d = 36

The best way to go about this is to solve it by substitution since we have a 1d in the first equation. We will solve that equation for d since that makes the most sense algebraically. Doing that,

1d = 40 - 6h.

Now that we know what d equals, we can sub it into the second equation where we see a d. In order,

4h + 3d = 36 becomes

4h + 3(40 - 6h) = 36 and then simplify. By substituting into the second equation we eliminated one of the variables. You can only have 1 unknown in a single equation, and now we do!

4h + 120 - 18h = 36 and

-14h = -84 so

h = 6.

That means that each hen costs $6. Since the cost of a duck is found in the bold print equation above, we will sub in a 6 for h to solve for d:

1d = 40 - 6(6) and

d = 40 - 36 so

d = 4.

That means that each duck costs $4.

Answer:

  B.  x = a(y - v)^2 + h

Step-by-step explanation:

The basic equation is ...

  x = f(y)

  x = y^2

To translate the vertex from (0, 0) to (h, v), we replace x with (x-h) and y with (y-v). Now, we have ...

  x -h = (y -v)^2

To scale the graph horizontally by a factor of "a", we multiply the right side by "a":

  x -h = a(y -v)^2

Adding h gives the form you want to compare to the answer list:

  x = a(y -v)^2 +h

Answer: £2.4

Step-by-step explanation:

From the question, Erin buys 3 packs of potatoes costing £2 each, 4 packs of carrots for £2 per pack, and 4 turnips costing 90p each.

Total cost of potatoes = 3 × £2 = £6

Total cost of carrots = 4 × £2 = £8

Total cost of turnips = 4 × 90p = £360p = £3.6

The total cost of things bought by Erin will now be:

= £6 + £8 + £3.6

= £17.6

If she pays with a £20 note, she will collect a change of:

= £20 - £17.6

= £2.4
